Goldilocks stars are best places to look for life

To date astronomers have discovered over 4,000 planets orbiting other stars. Statistically, there should be over 100 billion planets in our Milky Way galaxy. They come in a wide range of sizes and characteristics, largely unimagined before exoplanets were first discovered in the mid-1990s. The biggest motivation for perusing these worlds is to find "Genesis II," a planet where life has arisen and evolved beyond microbes. The ultimate payoff would be finding intelligent life off the Earth.

Hubble detects smallest known dark matter clumps

When searching for dark matter, astronomers must go on a sort of "ghost hunt." That's because dark matter is an invisible substance that cannot be seen directly. Yet it makes up the bulk of the universe's mass and forms the scaffolding upon which galaxies are built. Dark matter is the gravitational "glue" that holds galaxies as well as galaxy clusters together. Astronomers can detect its presence indirectly by measuring how its gravity affects stars and galaxies.

Cosmic magnifying glasses yield independent measure of universe's expansion

A team of astronomers using NASA's Hubble Space Telescope has measured the universe's expansion rate using a technique that is completely independent of any previous method.

Stellar heavy metals can trace history of galaxies

Astronomers have cataloged signs of nine heavy metals in the infrared light from supergiant and giant stars. New observations based on this catalog will help researchers to understand how events like binary neutron star mergers have affected the chemical composition and evolution of our own Milky Way Galaxy and other galaxies.

NEID exoplanet instrument sees first light

The new NEID instrument, now installed at the 3.5-meter WIYN telescope at Kitt Peak National Observatory in Southern Arizona, USA, has made its first observations. The NSF-NASA funded instrument is designed to measure the motion of nearby stars with extreme precision—roughly three times better than the previous generation of state-of-the-art instruments—allowing us to detect, determine the mass of, and characterize exoplanets as small as Earth.

Researchers take exploration of key 'building block' particles into space

As part of SpaceX's CRS-19 resupply mission to the International Space Station (ISS) launched Dec. 5, researchers from NASA, New Jersey Institute of Technology (NJIT) and New York University (NYU) are set to begin a new scientific investigation to explore how a group of microscopic particles considered key "building blocks" for materials and products here on Earth, known as colloidal particles, behave and form in zero-gravity.

Moon river: Rocket part ferried on the mighty Mississippi

With a brass band playing and a parade of workers sporting Mardi Gras beads, a huge component of a new rocket system was wheeled slowly from a New Orleans spacecraft factory on Wednesday to a barge that will float it up the Mississippi River for testing.

A new tool for 'weighing' unseen planets

A new instrument funded by NASA and the National Science Foundation called NEID (pronounced "NOO-id"; sounds like "fluid") will help scientists measure the masses of planets outside our solar system—exoplanets—by observing the gravitational pull they exert on their parent stars. That information can help reveal a planet's composition, one critical aspect in determining its potential habitability.

WHOI underwater robot takes first-known automated sample from ocean

WHOI's robot, Nereid Under Ice (NUI), samples a patch of sediment from the mineral-rich floor of Kolumbo volcano off Santorini Island, Greece. This is the first known automated sample taken by a robot in the ocean.

Water could disappear from Mars faster than expected

Mars is losing water more quickly than theory and observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars as sunlight and chemistry disassociate water molecules into hydrogen and oxygen atoms that the weak gravity cannot prevent from escaping into space.

Lucy mission now has a new destination

Less than two years before launch, scientists associated with NASA's Lucy mission, led by Southwest Research Institute, have discovered an additional small asteroid that will be visited by the Lucy spacecraft.

The famous, but bizarre, 'rubber hand illusion' could help people who suffer from obsessive compulsive disorder overcome their condition without the often unbearable stress of exposure therapy, suggests new research.

Abnormal neuron activity manifests as parental neglect

The brain undergoes dramatic change during the first years of life. Its circuits readily rewire as an infant and then child encounters new sights and sounds, taking in the world and learning to understand it. As the child matures and key developmental periods pass, the brain becomes less malleable—but certain experiences create opportunities for parts of the adult brain to rewire and learn again.

Study paves way for new vaccines to protect infants against infections

A new Penn Medicine study puts researchers within closer reach of vaccines that can protect infants against infections by overcoming a mother's antibodies, which are known to shut down immune defenses initiated by conventional vaccines. That hurdle largely explains why vaccinations for infectious diseases like influenza and measles not given until six to 12 months of age. Findings from the preclinical study were published online today in Science Translational Medicine.

Getting to the heart of heartbeats: Cardiac thin filament structure and function revealed

Researchers at Osaka University used electron cryomicroscopy (CryoEM) to image essential cardiac muscle components, known as thin filaments, with unprecedented resolution. They also discovered the mechanism by which these filaments regulate heart beat via cardiac muscle contractions in the presence or absence of calcium ions by changing their conformations. This work may have application in the development of new drugs for treating heart conditions caused by mutations that affect these structures and functions.

Researchers explain link between emotion and addictive substance use

What drives a person to smoke cigarettes—and keeps one out of six U.S. adults addicted to tobacco use, at a cost of 480,000 premature deaths each year despite decades of anti-smoking campaigns? What role do emotions play in this addictive behavior? Why do some smokers puff more often and more deeply or even relapse many years after they've quit? If policy makers had those answers, how could they strengthen the fight against the global smoking epidemic?

Baby and adult brains 'sync up' during play, study finds

Have you ever played with a baby and felt a sense of connection, even though they couldn't yet talk to you? New research suggests that you might quite literally be "on the same wavelength," experiencing similar brain activity in the same brain regions.

Poor sexual health more common in UK women than men

Poor sexual health in the UK is more common in women and affects them in more diverse ways than men, according to a UK study published in the open access journal BMC Public Health. Out of 12,132 men and women included in the study, 17% of men and 47.5% of women reported poor sexual health. Several important at-risk groups may be in danger of being overlooked by current sexual health intervention efforts, so more tailored approaches may be needed, the authors conclude.

AI can be used to detect and grade prostate cancer

Researchers at Karolinska Institutet in Sweden and Tampere University in Finland have developed a method based on artificial intelligence (AI) for histopathological diagnosis and grading of prostate cancer. The AI-system has the potential to solve one of the bottlenecks in today's prostate cancer histopathology by providing more accurate diagnosis and better treatment decisions. The study, presented in the scientific journal The Lancet Oncology, shows that the AI-system is as good at identifying and grading prostate cancer as world-leading uro-pathologists.

Study shows giving entire course of radiation treatment in less than a second is feasible

Cancer patients may one day be able to get their entire course of radiation therapy in less than a second rather than coming in for treatment over the course of several weeks, and researchers in the Abramson Cancer Center of the University of Pennsylvania have taken the first steps toward making it a reality. In a new report published today in the International Journal of Radiation Oncology, Biology, and Physics, researchers detail how they used proton radiation to generate the dosage needed to theoretically give a cancer patient their entire course of radiotherapy in one rapid treatment. It's known as FLASH radiotherapy, and it's an experimental paradigm that could represent a sea change for the world of oncology in the future. In this study, researchers also found FLASH demonstrated the same effect on tumors as traditional photon radiation while sparing healthy tissue due to the shorter exposure time.

In health care, does 'hotspotting' make patients better?

The new health care practice of "hotspotting"—in which providers identify very high-cost patients and attempt to reduce their medical spending while improving care—has virtually no impact on patient outcomes, according to a new study led by MIT economists.

Researchers surprised by high levels of alcohol consumption among cancer survivors

New research in the January 2020 issue of JNCCN—Journal of the National Comprehensive Cancer Network uses data from the National Health Interview Survey (NHIS) from 2000 to 2017 to examine self-reported drinking habits among people reporting a cancer diagnosis. The researchers found that of 34,080 survey participants, 56.5 percent were current drinkers, 34.9 percent exceeded moderate drinking levels, and 21 percent engaged in binge drinking. This is the first large study to be done on alcohol use in the oncology population. Given that alcohol has been identified as a risk factor for several cancers (and contributed to 5.8 percent of cancer deaths in 2012), the researchers were surprised by how high those numbers were.

Scientists unveil chemotherapy resistance mechanism related to p53 mutation

More than half of cancer cases worldwide are associated with genetic mutations in p53, the protein responsible for protecting DNA from changes that can lead to cancer. When this protein deforms, it not only loses its protective capacity, but can also gain new functions, acting as a "traitor" and contributing to the spread of the tumor by forming protein clusters that may be resistant to chemotherapy. The mechanisms by which this occurs and how it causes drug resistance are not yet fully understood.

New findings: Body clock affects how the immune system works

All life on Earth has evolved to cope with a rotating planet which results in the predictable transition between day and night.

The findings, which appear in an upcoming issue of JASN, highlight the importance of protecting the kidney health of individuals diagnosed with cardiovascular disease.

The meaning of life: A psychologist's view

The search for meaning in life is a familiar challenge to many of us. Some materialist scientists and philosophers consider it a futile search. Prominent atheist Richard Dawkins, for example, claims that human beings are just "throwaway survival machines" whose only purpose is to survive and replicate genes.

Neuropeptide reduces epileptic seizures in human brain tissue

One challenge facing researchers who study brain diseases is that for understandable reasons it is difficult to obtain human brain tissue for experiments. For that reason, experimental models are used, such as rodent studies, but one problem is that these often cannot be directly translated to human conditions.

Peering into the genome of brain tumor

In defense of 'imprecise' medicine: The benefits of routine treatments for common diseases

The NHS states that it "will be the world-leading healthcare system in its use of cutting-edge genomic technologies to predict and diagnose inherited and acquired disease, and to personalize treatments and interventions". As all diseases are either inherited or acquired, this is no modest claim.

Fitness gurus and 'muscular Christianity': How Victorian Britain anticipated today's fitness craze

The Victorian era is often remembered as an age of industrial innovation, staunch morals and hard work. When we imagine the stereotypical Victorian, we often picture stiff collars and heavy, head-to-toe dresses—not celebrity weightlifters or homemakers practicing calisthenics. But it turns out our obsession with physical fitness isn't just because of 20th century stars like Jane Fonda, Arnold Schwarzenegger, and Dwayne "The Rock" Johnson. In fact, the Victorian age saw the beginnings of modern celebrity fitness culture and new forms of exercise—which we might credit for our current obsession today.

Dazed and confused about the benefits of CBD? You're not alone.

VR: Not suited to visual memory?!

Kyoko Hine, Assistant Professor at the Department of Computer Science and Engineering, Toyohashi University of Technology and a research team at Tokyo Denki University have found that virtual reality (VR) may interfere with visual memory. In recent years, there has been high expectations that VR will be used effectively not only in multimedia and entertainment, but also in educational settings. However, in order to benefit society, IT needs to take human characteristics into consideration. The nature of VR can become known through scientific verification based on experiments like the work undertaken in this research.

Nuclear radiologists 'outsmart' prostate cancer with an apparently ineffective drug

When a non-scientist tries to imagine a scientist, the image that often arises is one of a somewhat remote, rather idealistic genius sitting alone in their room or laboratory and somehow discovering the most amazing things without every having contact with the 'normal' world. But science is just as much a part of life as any other activity. So it's perhaps not all that surprising to learn that—just like in normal life—intuition can occasionally play a major role in scientific progress.

Prostate cancer can now be diagnosed better using artificial intelligence

Researchers at Radboud university medical center have developed a 'deep learning' system that is better than most pathologists at determining the aggressiveness of prostate cancer. The AI system, which uses tissue samples to arrive at its diagnosis, taught itself to identify prostate cancer based on data from over 1200 patients. The Radboud team is now working with researchers from the Karolinska Institute in Sweden and Kaggle, a Google subsidiary, with the intention to continue developing these methods as part of a major international competition.

Psoriasis: Towards a novel therapeutic approach

Psoriasis is a frequent skin inflammatory disorder affecting 3% of the population. Psoriasis is characterized by hyperproliferation and defect of epidermal differentiation, leading to the scaly appearance of the skin. Psoriatic skin also presents an increase in blood vessels, leading to the redness of the skin lesions and is associated with immune infiltration.

Addressing the emotional toll of pediatric chronic conditions

Be it autism, sickle cell or other life-disrupting health conditions, being the parent of a child with a chronic condition takes a psychological toll. For too many families, however, emotional and behavioral health support has been far too difficult to obtain.

Study reveals insights on hidden sexual-arousal disorder

Persistent genital arousal disorder (PGAD)—which is almost exclusively experienced by females and characterized by spontaneous and unwanted sexual arousal unrelated to desire—can compromise individuals' mental health and well-being and severely damage relationships with partners.

Waking up dormant dopaminergic neurons to reverse Parkinson's disease

As many as seven to 10 million people in the world are thought to live with Parkinson's disease (PD). Being the second most common neurodegenerative disease, PD severely affects patients' quality of life, not just brining movement abnormalities. Despite its prevalence and negative impact, current medical treatments for PD rely on alleviating PD symptoms with little efforts to explore ways to reverse the symptoms.

Study: Judo may help health, social interactions of children with autism

Judo may be just the right sport to increase the physical activity level among children with autism spectrum disorder (ASD) and holds promise for reducing sedentary behavior, which is linked to obesity and diabetes, according to a new study from the University of Central Florida.

Kangaroo mother care reduces infant mortality

Common genetic defect in prostate cancer inspires path to new anti-cancer drugs

Like security screening to make sure nothing harmful makes its way into a crowded area, cells in the human body use checkpoints to control their growth and prevent harmful mutations from making their way into new cell populations and causing trouble. Every cell that divides and replicates its DNA must clear at least three checkpoints—all of which call on specialized genes known as tumor suppressors.

Pornography is not a 'public health crisis': researchers

Existing evidence suggests pornography may negatively affect some individuals, but it does not qualify as a public health crisis, and calling it one could cause harm.

BPA's counterpart replacement BPS can hinder heart function within minutes of a single exposure, according to a new University of Guelph study.

Parents aren't powerless when it comes to sleep-deprived teenagers

Teenagers in the US simply don't get enough shut eye. The consequences of this epidemic of sleep deprivation are extensive and include increasing rates of anxiety and depression among adolescents, as well as suicidal thoughts and actions. Sleep-deprived teens are more likely to be involved in car crashes, and run a higher risk of injury during sports-related activities.

Less severe cases of diarrheal illness can still lead to child mortality, research shows

Diarrheal diseases are a leading cause of death for young children, accounting for nine percent of all deaths worldwide in children under five years of age, with most occurring in children under two years of age. Now, researchers at the University of Maryland School of Medicine (UMSOM) found that even milder cases of diarrheal diseases can lead to death in young children.

Food textures affect perceptions of healthiness

New research has demonstrated how food producers could change the surface texture of products to change people's perceptions and promote healthy eating.

Metabolic syndrome associated with increased risk of blood clot recurrence

People with metabolic syndrome—a set of conditions including obesity, impaired glucose metabolism, elevated levels of fats and cholesterol in the blood, and high blood pressure—are more likely to experience recurrent blood clots, according to a new study published today in Blood Advances. Among patients diagnosed with a type of blood clot known as deep vein thrombosis (DVT), those who also had markers of metabolic syndrome were more likely to experience another venous thromboembolism (VTE) event. Furthermore, as the number of metabolic syndrome conditions that the patients exhibited increased, so too did their likelihood of experiencing VTE recurrence.

Rejuvenating the brain: More stem cells improve learning and memory of old mice

The older we get the more our brains will find it difficult to learn and remember new things. The research group led by Professor Federico Calegari used a method to stimulate the small pool of neural stem cells that reside in the brain in order to increase their number and the number of neurons generated by those stem cells. Additional neurons could survive and form new contacts with neighboring cells in the brain of old mice.

Lack of insurance is cause of survivorship gap in minorities with cancer, study shows

Lack of insurance coverage is a major cause of delayed breast cancer screening and treatment among minority women, which could lead to a decrease in a patient's chance of survival. Nearly half of the disparity in later-stage diagnosis between non-Hispanic white women and black, Hispanic and Asian/Pacific Islander women was mediated by being uninsured or underinsured, according to a new study conducted at the University of Illinois at Chicago and Boston Medical Center/Boston University School of Medicine.

First genomic study of puberty yields insights into development and cancer

In the first-ever genome-scale analysis of the puberty process in humans, researchers at Huntsman Cancer Institute (HCI) at the University of Utah (U of U) outline distinct and critical changes to stem cells in males during adolescence. They further outline how testosterone, and the cells that produce testosterone, impact stem cells in male reproductive organs. The researchers believe this study adds dramatically to a foundation of knowledge that may yield insights into critical areas of human health, including infertility and cellular changes that lead to cancer and other diseases.

Biology news

Of ants and men: Ant behavior might mirror political polarization

Could the division of labor in an anthill be driven by the same social dynamics governing the gap between liberals and conservatives? That was the surprising question tackled by Princeton biologists Chris Tokita and Corina Tarnita.

How do fruit flies see in color? Study uncovers human-like brain circuit at work

Columbia scientists have identified a brain circuit that drives fruit flies' ability to see in color—and found that it bears a striking resemblance to the circuitry behind our own capacity for color vision. These findings shed light on the fundamental, yet mysterious, process by which information about light waves is transmitted from the eye to the brain. This research will not only fuel new investigations into how color vision works in flies and humans, but could also spur efforts to develop algorithms that help computers see in color.

'Resurrection ecology' of 600-year-old water fleas used to understand pollution adaptation

One of the leading threats to lakes since the rise of agriculture are runoffs from fertilizer, in the form of high phosphorus levels. These can trigger devastating events like eutrophication, where deadly algal blooms thrive on phosphorus, and in the process, outcompete and choke off vital nutrients from the rest of the lake.

Shark and ray vision comes into focus

Vision is a crucial sense for most animals, and vertebrates have evolved a highly adaptable set of opsin genes that generate light-sensitive pigments to decode the retinal image. These opsins include a rod opsin to help see in low light, and four classes of cone opsins to see in bright light and detect colors across the visible light spectrum.

Biologists identify pathways that extend lifespan by 500%

Scientists at the MDI Biological Laboratory, in collaboration with scientists from the Buck Institute for Research on Aging in Novato, Calif., and Nanjing University in China, have identified synergistic cellular pathways for longevity that amplify lifespan fivefold in C. elegans, a nematode worm used as a model in aging research.

New technology employing single cell genome sequencing of the parasite that causes malaria has yielded some surprising results and helps pave the way for possible new intervention strategies for this deadly infectious disease, according to Texas Biomedical Research Institute Assistant Professor Ian Cheeseman, Ph.D. Dr. Cheeseman was Principal Investigator of a three-year study published in the January 2020 edition of Cell Host & Microbe, a high-impact peer-reviewed publication.

How bacterial evolution of antibiotic arsenals is providing new drug blueprints

Scientists from Trinity College Dublin have discovered that two very different species of bacteria have evolved distinct, powerful antibiotic arsenals for use in the war against their bacterial neighbours [Thursday 9th January, 2020]. By blueprinting precisely how the antibiotics function against methicillin-resistant Staphylococcus aureus (MRSA), the scientists have provided new options for drug designers seeking to hold back the global threat that antimicrobial resistance poses humanity.

Ancient iron-sulfur-based mechanism monitors electron flow in photosynthesis

A delicate balance of electrons flowing through the photosynthetic machinery is essential to a plant's ability to turn sunlight into energy and its survival. Understanding the factors that regulate this balance is key for plant breeders who may want to improve light energy conversion in crop plants for increased yield.

Selfless African grey parrots get by with a little help from friends (Update)

Acting selflessly to help others in need was long thought to be a trait confined to mammals, in particular humans and some great ape species like bonobos and orangutans.

Scientists transform a BBQ lighter into a high-tech lab device

Researchers have devised a straightforward technique for building a laboratory device known as an electroporator—which applies a jolt of electricity to temporarily open cell walls—from inexpensive components, including a piezoelectric crystal taken from a butane lighter.

Acidic environment could boost power of harmful pathogens

When food we've swallowed reaches our stomachs, it finds an acidic environment. The low pH in the stomach helps to begin digestion—and has been thought to kill the bacteria that hides in food that otherwise could harm our bodies.

Prosocial and tolerant parrots help others to obtain food

Parrots are considered extraordinarily clever animals. Alex, the famous Harvard-based African grey parrot, communicated with a vocabulary of more than 500 human words, could answer questions and classify objects spontaneously. Scientists from the Max-Planck-Institute for Ornithology based at the research station outpost for parrot comparative cognition in the Loro Parque in Tenerife, Spain, have shown that parrots exhibit a high level of social intelligence and cooperativeness. They readily help others, even when there is no immediate opportunity for reciprocation. Moreover, they reciprocate received favours and do not appear jealous, if conspecifics obtain a better reward than themselves. This further supports that they have evolved a level of intelligence comparable to that of great apes, crows and dolphins.

Large 'herbivores of the sea' help keep coral reefs healthy

Selective fishing can disrupt the delicate balance maintained between corals and algae in embattled Caribbean coral reefs. Removing large parrotfish, which graze on algae like large land mammals graze on grasses, can allow the algae to overtake the corals, with potentially dire consequences for reef health. New experimental research suggests that maintaining a healthy size distribution of parrotfishes in a sea floor ecosystem through smart fishing practices could help maintain reefs that are already facing decline due to climate change.

Study finds deforestation is changing animal communication

Deforestation is changing the way monkeys communicate in their natural habitat, according to a new study.

Scientists learn how to increase corn crop yields

NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its resources away from maintaining an overprepared immune system and into enhanced seed production. Now, a team led by CSHL scientist David Jackson has found a gene that could help tweak that balance.

New ways to generate totipotent-like cells

Totipotency is set to become a key tool for research and future medical applications. Finding efficient ways to generate totipotent-like cells is therefore crucial. In a new study, a group of researchers at Helmholtz Zentrum München found that totipotent-like cells can be induced by manipulating the availability of metabolites in pluripotent cells. These findings open up new possibilities for cell reprogramming.

Doctors come together to save eyesight of 3-year-old gorilla

Animal care specialists at the San Diego Zoo Safari Park were concerned when they noticed cloudiness in the left eye of Leslie, a three-year-old female western lowland gorilla. Closer inspection confirmed the lens had changed and the left eye was shifting haphazardly, prompting Leslie to favor use of her right eye.

New research reveals connection between drug treatments and antimicrobial resistance in cattle disease

A new study from Kansas State University on the treatment of non-responding cases of bovine respiratory disease, known as BRD, conducted by Hans Coetzee and his collaborators from Iowa State University, sheds light on the relationship between drug treatments and the emergence of antimicrobial resistance.

Coordination by remote control

Protein filament systems within cells are subject to constant reorganization, which is in part mediated by the actions of motor proteins. LMU researchers have now shown that motor-driven movements can propagate through such networks.

Improved functioning of diverse landscape mosaics

It is well-established that biodiverse ecosystems generally function better than monocultures. Ecologists at the University of Zurich have now shown that the same is true on a larger scale: Having a mix of different land-covers including grassland, forest, urban areas and water bodies improves the functioning and stability of a landscape—irrespective of the plant species diversity, region and climate.

Monkeys smashing nuts with stones hint at how human tool use evolved

Human beings used to be defined as "the tool-maker" species. But the uniqueness of this description was challenged in the 1960s when Dr. Jane Goodall discovered that chimpanzees will pick and modify grass stems to use to collect termites. Her observations called into question homo sapiens' very place in the world.

Moths' flight data helps drones navigate complex environments

The flight navigation strategy of moths can be used to develop programs that help drones to navigate unfamiliar environments, report Ioannis Paschalidis at Boston University, Thomas Daniel at University of Washington, and colleagues, in the open-access journal PLOS Computational Biology.

The claw disease tyloma is primarily genetic in cows

Scientists at Martin Luther University Halle-Wittenberg (MLU) and Georg August University Göttingen have succeeded in proving that a claw disease in cows is primarily genetic. Until now, the occurrence of interdigital hyperplasia has mostly been attributed to poor hygiene conditions in the barn. However, a team led by Professor Hermann Swalve discovered a farm in which the disease occurred frequently and was able to identify the gene responsible. As a result, the disease may now be contained through selective breeding.

Vector-borne causes of fever in cats demand year-round preventive therapy

Increased body temperature is the single-most commonly noted abnormal finding for the medical practitioner. While it may be a sign of something relatively innocuous, it can also be an indication of underlying critical illness. In cats, an elevated body temperature equates to a reading in excess of 39.2°C or 102.5°F and, as in humans, it can arise as a result of two major mechanisms: hyperthermia and fever. Hyperthermia refers to a sudden and uncontrolled increase in temperature owing to failure of the body's thermoregulatory mechanism. By contrast, in fever (or pyrexia, from the Greek for 'fire' or 'burning heat'), the body's hypothalamic set-point is increased, secondary to the release of pyrogens, as the body's adaptive response to a pathological state.

If the pines disappear, can it still be called Big Pine Key?

More than 30 percent of the trees on Big Pine Key died in the months following Hurricane Irma.

AAFP releases updated feline retrovirus guidelines to the veterinary community
