Mini-flares potentially jeopardize habitability of planets circling red dwarf stars

Cool dwarf stars are hot targets for exoplanet hunting right now. The discoveries of planets in the habitable zones of the TRAPPIST-1 and LHS 1140 systems, for example, suggest that Earth-sized worlds might circle billions of red dwarf stars, the most common type of star in our galaxy. But, like our own sun, many of these stars erupt with intense flares. Are red dwarfs really as friendly to life as they appear, or do these flares make the surfaces of any orbiting planets inhospitable?

R Aquarii: Watching a volatile stellar relationship

In biology, "symbiosis" refers to two organisms that live close to and interact with one another. Astronomers have long studied a class of stars—called symbiotic stars—that co-exist in a similar way.

Medicine & Health news

Building a better blood-brain barrier model

Delivering drugs to the brain is no easy task. The blood-brain barrier -a protective sheath of tissue that shields the brain from harmful chemicals and invaders - cannot be penetrated by most therapeutics that are injected into a person's blood stream. But for treating diseases of the central nervous system and cancers such as glioblastoma, it's essential to get drugs across this barrier and deliver them to where they are needed most. Current research models that are used to study or imitate the blood-brain barrier have a number of limitations. Investigators at Brigham and Women's Hospital have developed an innovative but easily implemented approach that uses "spheroids" to mimic the blood-brain barrier more accurately, and appears to overcome several challenges for discovering and advancing new drugs for treating brain conditions. They report their results June 6 in Nature Communications.

Energetic expenditure not the only factor when judging physical effort of movements

Scientists from the German Primate Center, led by Dr. Pierre Morel, have determined which characteristics of an arm movement influence the subjective effort associated with this movement. In a study publishing on June 6 in the open access journal PLOS Biology they found that duration, biomechanics and force had an influence on the effort, while movement amplitudes had no effect. Moreover, their results shed light on a postulated link between two important functions of the brain: optimizing action selection in decision-making and in movement execution.

Is white or whole wheat bread 'healthier?' Depends on the person

Despite many studies looking at which bread is the healthiest, it is still not clear what effect bread and differences among bread types have on clinically relevant parameters and on the microbiome. In the journal Cell Metabolism on June 6, Weizmann Institute researchers report the results of a comprehensive, randomized trial in 20 healthy subjects comparing differences in how processed white bread and artisanal whole wheat sourdough affect the body.

Study could help explain link between seizures and psychiatric disorders

In a new study published in Cell Reports, scientists at the Gladstone Institutes identified different types of neurons in a brain region called the reticular thalamus. A better understanding of these cells could eventually help explain how both seizures and certain psychiatric disorders can occur at the same time.

3-D skin made of stem cells treats backbone birth defect in rodents

Myelomeningocele is a severe congenital defect in which the backbone and spinal canal do not close before birth, putting those affected at risk of lifelong neurological problems. In a preclinical study published June 6th in Stem Cell Reports, researchers developed a stem cell-based therapy for generating skin grafts to cover myelomeningocele defects before birth. They first generated artificial skin from human induced pluripotent stem cells (iPSCs), and then successfully transplanted the skin grafts into rat fetuses with myelomeningocele.

Finnish study shows increase in economically valuable personality traits

(Medical Xpress)—A team of researchers affiliated with several institutions in Finland has found that personality traits that convey economic advantages rose over a 15-year study period. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of data on a large portion of males born in Finland over the years 1962 to 1978 and what they found.

Restoring cardiac function with a matrix molecule

Heart disease remains the leading cause of death worldwide, yet the few available treatments are still mostly unsuccessful once the heart tissue has suffered damage. Mammalian hearts are actually able to regenerate and repair damage - but only up to around the time of birth. Afterward, that ability disappears, seemingly forever. Research at the Weizmann Institute of Science has uncovered a molecule in newborn hearts that appears to control the renewal process. When injected into adult mouse hearts injured by heart attacks, this molecule, called Agrin, seems to "unlock" that renewal process and enable heart muscle repair. These findings, published today in Nature, are already pointing to new directions for research on restoring the function of damaged hearts.

A star is born: Lesser-known brain cell takes center stage

Neurons have long enjoyed the spotlight in neuroscience—and for good reason: they are incredibly important cellular actors. But, increasingly, star-shaped support cells called astrocytes are being seen as more than bit players in the brain's rich pageant.

Research study gives new insight into how cancer spreads

A research study led by University of Minnesota engineers gives new insight into how cancer cells move based on their ability to sense their environment. The discovery could have a major impact on therapies to prevent the spread of cancer.

A 12-hour biological clock coordinates essential bodily functions

Some bodily activities, sleeping, for instance, mostly occur once every 24 hours; they follow a circadian rhythm. Other bodily functions, such as body temperature, cognitive performance and blood pressure, present an additional 12-hour cycle, but little is known about the biological basis of their rhythm. A team of scientists from various institutions, including Baylor College of Medicine, has revealed that, in addition to 24-hour clocks, mammals and other organisms have 12-hour clocks that are autonomous, work independently from 24-hour clocks and can be modified by external factors. Studying 12-hour clocks is important because altered 12-hour cycles have been linked to human disease. The study appears in Cell Metabolism.

Cancer cells send signals boosting survival and drug resistance in other cancer cells

Researchers at University of California San Diego School of Medicine report that cancer cells appear to communicate to other cancer cells, activating an internal mechanism that boosts resistance to common chemotherapies and promotes tumor survival.

New possible target for cancer treatment

Scientists at Karolinska Institutet in Sweden report that cancer cells and normal cells use different 'gene switches' in order to regulate the expression of genes that control growth. In mice, the removal of a large regulatory region linked to different types of cancer caused a dramatic resistance to tumour formation, but did not affect normal cell growth. The findings, published in the scientific journal eLife, highlight the possibility of developing highly specific cancer drugs with fewer side effects.

Gut bacteria could protect cancer patients and pregnant women from Listeria, study suggests

Researchers at Memorial Sloan Kettering Cancer Center in New York have discovered that bacteria living in the gut provide a first line of defense against severe Listeria infections.

Heart healing therapy shows promise

A potential therapy to help patients recover from a heart attack has been identified by researchers.

How hard is it to recognise that you are experiencing a delusion?

When people experience delusions or hallucinations there is usually some loss of contact with reality whereby normal processes of thought and perception are disturbed. As humans, we are all susceptible to experiencing anomalous mental states such as this. In everyday life, for example, mentally healthy people distort reality to enhance their self-esteem and maintain beliefs about their self-agency.

Anxious people worry about risk, not loss

Life is a series of choices. Every time you make a decision, there is a possibility that things won't go as expected (risk) or that something bad will happen (loss). Aversion to risk and loss have powerful influences on how we make decisions. In a new paper in Biological Psychiatry, co-senior authors Dr. Jonathan Roiser and Dr. Oliver Robinson, both of the Institute of Cognitive Neuroscience, University College London, and colleagues studied the influence of risk and loss aversion in people with anxiety, a disorder characterized by debilitating avoidance behavior and difficulties making daily-life decisions.

Dogs help in breast carcinoma research

Cancer of the mammary glands in dogs is very similar to human breast carcinoma. For this reason, treatment methods from human medicine are often used for dogs. Conversely, scientific knowledge gained from canine mammary tumors may also be important to human medicine. Researchers from the University of Zurich were able to show how similar these tumors are in both dogs and humans.

A new approach to combatting anxiety states, pain and inflammation

Endogenous cannabinoids (endocannabinoids) play an important role in the brain and immune system. Bern researchers from the National Centre of Competence in Research (NCCR) "TransCure" have now found a new way to influence the endocannabinoid system. Anti-inflammatory, analgesic as well as anxiolytic effects could be achieved in an animal model.

Stem cells may be the key to staying strong in old age

University of Rochester Medical Center researchers have discovered that loss of muscle stem cells is the main driving force behind muscle decline in old age in mice. Their finding challenges the current prevailing theory that age-related muscle decline is primarily caused by loss of motor neurons. Study authors hope to develop a drug or therapy that can slow muscle stem cell loss and muscle decline in the future.

A novel approach to seeing dengue infection in the body

Commonly used to detect solid tumours, positron emission tomography (PET) paired with the glucose metabolism probe, fluorodeoxyglucose (FDG), is considered 'old' technology in the field of cancer. A team from Duke-NUS Medical School (Duke-NUS) and Singapore General Hospital (SGH) has now found a new use for this 'old' technology in another field: infectious diseases research. Using FDG-PET as an imaging tool for dengue infection in mouse models, the team has potentially uncovered a novel and non-invasive way to track the infection in real-time and more accurately assess the effectiveness of new treatments for dengue.

New surgical techniques help save patients from life-threatening heart condition

Cardiac surgeons are successfully performing more extensive surgical repairs of type A aortic dissection—one of the highest risk operations in cardiothoracic surgery. These new surgical techniques, along with improved postoperative care, are resulting in better long-term outcomes and lower rates of complications, according to an article published online today in The Annals of Thoracic Surgery.

Promising new treatment option for chronic plaque psoriasis

Affecting more than 6 million Americans, chronic plaque psoriasis manifests as patches of red, scaly skin most frequently on the scalp, elbows and knees. Chronic plaque psoriasis most often appears in adolescence or mid-life and can require lifelong medication. Until the 1990s, physicians had few options to offer their patients with moderate-to-severe psoriasis. Up to a quarter of patients with psoriasis suffer from these more aggressive cases that can affect anywhere from 10 to a 100 percent of the surface of the skin.

Flu shot less effective for obese adults

Although influenza vaccines are currently the best forms of protection to safeguard people against getting the flu, they are not effective in all cases. A study from Melinda Beck's research team at the University of North Carolina at Chapel Hill in the US found that obese people - despite getting their shots - were still twice as likely to develop influenza or flu-like illnesses than others of healthy weight. The findings are published in Springer Nature's International Journal of Obesity.

Newly discovered disease mechanism for type 2 diabetes

A newly discovered mechanism behind reduced insulin production in type 2 diabetes is now being presented.

Take a coffee or tea break to protect your liver

Chronic liver diseases rank as the 12th cause of death worldwide and many of these disorders are associated with unhealthy lifestyles. Conversely, a healthier lifestyle can help prevent or reverse liver disease. Liver-related mortality is closely related to the development of cirrhosis, the final consequence of progressive fibrosis, i.e. scarring of the liver resulting from chronic inflammation. According to a new study published in the Journal of Hepatology, researchers found that drinking coffee and herbal tea may protect against liver fibrosis, estimated as the degree of liver stiffness, which is high in extensive scarring of the liver. Because these beverages are popular, widely available, and inexpensive, they could have the potential to become important in the prevention of advanced liver disease.

Computer-aided imaging technique could reduce risk of second breast cancer surgery

According to a recent study, one in four women with breast cancer who opt for a breast-saving lumpectomy will need a second surgery - increasing both costs and the risk of complications.

Trauma centers with American College of Surgeons verification have fewer complications

Major complications from injury—and consequently a longer hospital stay—are more likely for pediatric and elderly patients nationwide when treatment occurs at a trauma center not verified by the American College of Surgeons Committee on Trauma (ACS-COT), compared with an ACS-COT-verified center, according to new study findings. The study, which is published online as an "article in press" on the Journal of the American College of Surgeons website in advance of print publication, also finds an association between the lack of ACS-COT verification and an increased complication rate for patients of any age who sustain major injuries.

New research provides practical cooking tips for your red wine sauce

Can you get intoxicated by pouring beer or wine into your sauce or stew? This question is important if you are pregnant, have to drive a car or want to track calories. New research from the University of Copenhagen and the Carlsberg Research Center creates a model for how alcohol disappears from a sauce or another liquid dish cooked in a saucepan. This model can thus be used to control the alcohol content.

Anti-heroin vaccine found effective in non-human primates

A vaccine developed at The Scripps Research Institute (TSRI) to block the "high" of heroin has proven effective in non-human primates. This is the first vaccine against an opioid to pass this stage of preclinical testing.

Copaiba: Silver bullet or snake oil?

Sales of the essential oil copaiba [koh-pey-buh] are increasing, at least in part, because more than 54 million Americans suffer from some form of arthritis and 23.7 million are limited in their usual activity primarily due to pain. The conventional way to treat arthritis is using nonsteroidal, anti-inflammatory drugs (NSAIDs) as well as cyclo-oxygenase-2 inhibitors (COXIBs), which are not without adverse events like gastrointestinal bleeding, heart attacks and stroke. For arthritis sufferers, copaiba may turn out to be a silver bullet or, perhaps, snake oil.

Standard dosage for one lung cancer treatment may be too high

A new study published in the Journal of the National Cancer Institute indicates that the customary pembrolizumab dose for treatment of metastatic non-small cell lung cancer may be higher than is needed for effective treatment.

Drinking diet beverages during pregnancy linked to child obesity, study suggests

Children born to women who had gestational diabetes and drank at least one artificially sweetened beverage per day during pregnancy were more likely to be overweight or obese at age 7, compared to children born to women who had gestational diabetes and drank water instead of artificially sweetened beverages, according to a study led by researchers at the National Institutes of Health. Childhood obesity is known to increase the risk for certain health problems later in life, such as diabetes, heart disease, stroke and some cancers. The study appears online in the International Journal of Epidemiology.

Study identifies an enzyme inhibitor to treat Gulf War illness symptoms

At least 100,000 military veterans who served in the 1990-1991 Gulf War were exposed to chemical weapons, released into the air after the United States bombed an ammunition depot in Khamisiyah, Iraq. Today, many are still suffering from Gulf War Illness, a mysterious, multi-symptom disease that experts believe is linked to organophosphate nerve agents sarin and cyclosarin.

Study examines caregiving by family members, other unpaid individuals

It's estimated that nearly 30 percent of the 38.2 million people aged 65 or older in this country receive some form of caregiving, either for health reasons or to help manage daily activities. More than 65 percent of these older individuals rely on family members, friends, and even neighbors for assistance with things like preparing meals, bathing, taking medications, and getting transportation.

Should your primary care physician be a generalist or specialist? New study explores

Your primary care provider (PCP) is usually your first medical contact when you're ill. Beyond taking care of you when you're sick, PCPs help coordinate your health care and make sure you're up-to-date with your check-ups, tests, and immunizations.

Sequential options prompt future thinking, boost patience

When faced with a tempting choice, it can be hard to stop and think through the potential consequences, but new research suggests that framing the choice as a sequence of events can help us exercise patience by prompting us to imagine the future.

Difficulties diagnosing delirium in older adults after surgery

Delirium is a medical term for "sudden confusion." It is an abrupt, rapid change in mental function and can cause a wide variety of shifts in behavior ranging from aggression or agitation to feeling sleepy and inactive (or even a combination of several behaviors). When delirium occurs after an older person has had surgery, it's called "post-operative delirium."

New target found to attack an incurable brain tumor in children

A study published in Molecular Cancer Research reveals that a tumor suppressor gene p16 is turned off by a histone mutation (H3.3K27M), which is found in up to 70 percent of childhood brain tumors called diffuse intrinsic pontine glioma (DIPG). This insight suggests that restoring p16 is a promising therapeutic strategy. The authors have demonstrated that this can be accomplished in vitro using a drug that is approved for treatment of adult leukemia and other cancers.

With this the results support a more sustainable production of apple fruit, both from an environmental and a financial perspective.

How viruses hijack a host's energy supply

Viruses occupy a strange no-man's-land between the living and the nonliving. In order to reproduce, they must infect a living host and hijack its resources. But while it is understood that this parasitic relationship can lead to disease and death, few quantitative studies have examined the energetic cost of viral infections relative to the host's energy economy.

Genetic study shakes up the elephant family tree

New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago - ranging across Eurasia before it went extinct - is more closely related to today's African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant.

Astonishingly speedy brain mechanism helps bats get louder when necessary

When trying to be heard over noise, humans and animals raise their voices. It's a split-second feat, from ear to brain to vocalization, and Johns Hopkins University researchers are the first to measure just how fast it happens in bats: 30 milliseconds. That's just a tenth of the time it takes to blink an eye, and a record for audio-vocal response.

Invasive alien plant control assessed for the Kruger National Park in South Africa

Along with urban and agricultural encroachment and pollution mitigation, managing invasive alien species is a key intervention needed to protect biodiversity. Unfortunately, on a global scale there are not enough funds to meet the requirements for effective conservation everywhere, which means that scarce funds need to be allocated where they can be used most efficiently.

Why do Antarctic krill stocks fluctuate?

It is only six centimetres long, but it plays a major role in the Antarctic ecosystem: the small crustacean Euphausia superba (Antarctic krill). It's one of the world's most abundant species and the central diet of a number of animals in the Southern Ocean. For a long time, scientists have been puzzled why the size of krill stocks fluctuates so widely.

New way to detect Palmer amaranth in contaminated seedlots

Last summer, farmers in the Midwest got an unwelcome surprise after planting native seed on Conservation Reserve Program acres. Palmer amaranth, the aggressive and hard-to-kill weed, had established in droves. As a possible solution, some states declared Palmer a noxious weed, which prohibits its sale and transport.

Meals on the go: The physics of whales' eating habits

In a recent paper published in PLOS One, Saint Louis University professor of physics Jean Potvin, Ph.D., and biologist Alexander Werth, Ph.D. at Hampden-Sydney College, detail for the first time how baleen whales use crossflow filtration to separate prey from water without ever coming into contact with the baleen. Baleen are comb-like keratin plates that have replaced the teeth of the whale's ancestors about 30 million years ago and play the role of a filtration surface in their mouths. The researchers looked at how this type of feeding affects a whale's drag as it moves through the water and how this form of filtration is enhanced by a large body size.

Does the sex of a cell matter in research?

Over the last decade, many drugs that have been pulled from the market due to toxicity were withdrawn because they affected women more than men. It turns out, the studies that brought the drugs to market were designed using only male cells and animal models, a common flaw a Tulane endocrinologist is working to help correct.

Seed conservation in the remote South Atlantic

Islands have long held a fascination for scientists studying evolution and patterns of biodiversity, from Charles Darwin and Alfred Russell Wallace in the 19th century, to Robert MacArthur and E.O. Wilson in the 20th century, and continuing in the 21st century. Islands are often home to, for their size, a disproportionately large number of species with very narrow distributions, including single island endemics. They are also particularly vulnerable to the changes affecting the environment globally: habitat loss, climate change, and invasive species. Several island species are known to have been driven to extinction by human activity, with more perilously close to following them. At Kew, a key area of our work concerns the plant diversity of islands (UK, Madagascar, and the UK Overseas Territories in particular), the threats they face, and how best to conserve this unique life.
