Revealing the black hole at the heart of the galaxy

Including the powerful ALMA into an array of telescopes for the first time, astronomers have found that the emission from the supermassive black hole Sagittarius A* at the center of the galaxy comes from a smaller region than previously thought. This may indicate that a radio jet from Sagittarius A* is pointed almost directly toward us. The paper, led by the Nijmegen Ph.D. student Sara Issaoun, is published in The Astrophysical Journal.

Astronomers use split images of quasars to produce a new estimate of the Hubble constant

The question of how quickly the universe is expanding has been bugging astronomers for almost a century. Different studies keep coming up with different answers—which has some researchers wondering if they've overlooked a key mechanism in the machinery that drives the cosmos.

A fleeting moment in time

The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time—around 10,000 years, a blink of an eye in astronomical terms. ESO's Very Large Telescope captured this shell of glowing ionized gas—the last breath of the dying star whose simmering remains are visible at the heart of this image. As the gaseous shell of this planetary nebula expands and grows dimmer, it will slowly disappear from sight.

Milky Way's neighbors pick up the pace

After slowly forming stars for the first few billion years of their lives, the Magellanic Clouds, near neighbors of our own Milky Way galaxy, have upped their game and are now forming new stars at a fast clip.

Diet low in added sugars significantly improves fatty liver disease in children

A randomized clinical study of adolescent boys with nonalcoholic fatty liver disease (NAFLD) found that a diet low in free sugars (those sugars added to foods and beverages and occurring naturally in fruit juices) resulted in significant improvement in NAFLD compared to a usual diet.

Heart disease risk begins in the womb

Heart disease is the greatest killer in the world today, and it is widely accepted that our genes interact with traditional lifestyle risk factors, such as smoking, obesity and/or a sedentary life to promote an increased risk of cardiovascular disease. However, a new study in sheep, publishing January 22 in the open-access journal PLOS Biology, by a team from Cambridge University, finds that offspring whose mothers had a complicated pregnancy may be at greater risk of heart disease in later life, suggesting that our cards may be marked even before we are born.

Researchers identify neurons in the human visual cortex that respond to faces

A world where everyone has the same face would be very different than the one we know, in which faces are different, conveying essential information. For example, most people can instantly recognize a celebrity's face or the face of an old college friend, even after decades apart. Most people can sense the mood of a significant other just based on facial expression. Often, people can establish whether someone is trustworthy by looking at his or her face. Despite intensive research, how the brain conducts all these tasks is still a great mystery.

New study raises hopes of eradication of malaria

After major global successes in the battle against malaria, the positive trend stalled around 2015—apart from in Zanzibar in East Africa, where the disease is increasingly rare. In a new study published in BMC Medicine, researchers at Karolinska Institutet in Sweden explain why this was and show that new strategies are needed to eradicate the disease. One of the problems is a change in mosquito behaviour and selection in the parasites.

From microfluidics to metastasis

Circulating tumor cells (CTCs)—an intermediate form of cancer cell between a primary and metastatic tumor cell—carry a treasure trove of information that is critical to treating cancer. Numerous engineering advancements over the years have made it possible to extract cells via liquid biopsy and analyze them to monitor an individual patient's response to treatment and predict relapse.

Human respiratory viruses continue to spread in wild chimpanzees

Less than two years after the first report of wild chimpanzees in Uganda dying as a result of a human "common cold" virus, a new study has identified two other respiratory viruses of human origin in chimpanzee groups in the same forest.

New skin test detects prion infection before symptoms appear

Prions can infect both humans and animals, causing Creutzfeldt-Jakob disease (CJD) in humans, mad cow disease in cattle, and chronic wasting disease in elk and deer. The infectious, misfolded protein particles often go undetected as they destroy brain tissue, causing memory loss, mobility issues, and ultimately death. Preclinical detection of prions has proven difficult, but new research suggests skin samples hold early signs of prion disease that precede neurologic symptoms.

Leaving two-hour gap between dinner and bedtime may not affect blood glucose

Leaving a two-hour gap between the last meal of the day and bedtime doesn't seem to be associated with any discernible difference in blood glucose levels among healthy adults over the long term, suggests Japanese research published in the online journal BMJ Nutrition, Prevention & Health.

Widely available food in US workplaces: Perk or hazard?

Nearly a quarter of employed adults obtain foods and beverages at work at least once a week, according to a new study from the US Centers for Disease Control and Prevention (CDC) and published in the Journal of the Academy of Nutrition and Dietetics. Foods obtained at work are often high in calories, refined grains, added sugars, and sodium.

Payments to physicians may increase opioid prescribing

US doctors who receive direct payments from opioid manufacturers tend to prescribe more opioids than doctors who receive no such payments, according to new research published by Addiction. The report found that the association between payments and prescribing is strongest for hydrocodone and oxycodone, the most frequently prescribed opioids among Medicare patients (Americans of 65+ years and some younger people with disabilities). The Medicare population is estimated to have the highest and fastest growing prevalence of opioid use disorder in the US.

Artificial intelligence can dramatically cut time needed to process abnormal chest X-rays

New research has found that a novel Artificial Intelligence (AI) system can dramatically reduce the time needed to ensure that abnormal chest X-rays with critical findings will receive an expert radiologist opinion sooner, cutting the average delay from 11 days to less than 3 days. Chest X-rays are routinely performed to diagnose and monitor a wide range of conditions affecting the lungs, heart, bones, and soft tissues.

Blood test shows promise for early detection of severe lung-transplant rejection

Researchers have developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident. The test could make it possible for doctors to intervene faster to prevent or slow down so-called chronic rejection—which is severe, irreversible, and often deadly—in those first critical months after lung transplantation. Researchers believe this same test might also be useful for monitoring rejection in other types of organ transplants. The work was funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.

Liver transplants double for alcohol-related liver disease

The proportion of U.S. liver transplants for alcohol-associated liver disease (ALD) has doubled in the last 15 years, in part due to broader acceptance of waiving the mandated period of sobriety before transplants for this population, according to a study by researchers at UC San Francisco.

Branched-chain amino acids regulate the development and progression of cancer

Researchers at A*STAR's Singapore Bioimaging Consortium (SBIC) have discovered that branched-chain amino acids (BCAAs) in tumours can be targeted to prevent and treat cancer. Together with collaborators from the United States and National Cancer Centre Singapore (NCCS), they found that some cancers potently suppress the catabolism (breakdown) of BCAAs. This leads to BCAAs accumulating in tumours and activating a known pro-oncogenic pathway called mTOR. Researchers also found that dietary BCAA intake was directly linked to tumour development, suggesting that diets low in BCAAs could limit tumour progression and enhance overall survival.

Millennial burnout: Building resilience is no answer – we need to overhaul how we work

In a popular BuzzFeed article, Anne Helen Petersen describes how millennials (people born between 1981 and 1996) became "the burnout generation".

Are microbes causing your milk allergy?

In the past 30 years, food allergies have become increasingly common in the United States. Changes to human genetics can't explain the sudden rise. That is because it takes many generations for changes to spread that widely within a population. Perhaps the explanation lies in changes to our environment, particularly our internal environment. Shifting lifestyle practices over the last half-century – increasing antibiotic and antimicrobial use, surface sterilization, air filtration and changes to diet – have changed our internal environment and wiped out important bacteria with beneficial health effects.

Inability to integrate reward information contributes to undervalued rewards in schizophrenia

People with schizophrenia have a hard time integrating information about a reward—the size of the reward and the probability of receiving it—when assessing its value, according to a study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The inability to integrate the two factors correlated with more severe motivational deficits, suggesting that the impairment may contribute to decreased value placed on a reward, and thus reduced motivation to complete the task required to receive it.

Faulty molecular master switch may contribute to AMD

A signaling pathway controlled by transforming growth factor beta (TGF-beta) could be involved in the progression of age-related macular degeneration (AMD). Researchers at the National Eye Institute (NEI), part of the National Institutes of Health, have found that interrupting TGF-beta signals to immune cells called microglia causes the cells to enter an activated, inflammatory state. These activated microglia damage the retina, the light-sensitive tissue at the back of the eye. This damage is similar to cellular effects observed in AMD, a common cause of vision loss among older Americans. The study was published today in the journal eLife.

Researchers show synthetic flaxseed derivative helps heart function in septic mice

Sepsis is a life-threatening systemic inflammatory condition that develops in response to infection. One of its major complications is cardiovascular dysfunction, in which deterioration of the heart muscle, driven by decreased energy production resulting from reduced oxygen and nutrient supplies, frequently ends in organ failure. Now, in a new study published online in the Journal of Molecular and Cellular Cardiology, scientists at the Lewis Katz School of Medicine at Temple University (LKSOM) are the first to show that a novel synthetic compound derived from flaxseed, a whole grain celebrated for its potent antioxidant properties, can reverse this deterioration and improve heart function in mice with sepsis.

Frequent use of aspirin can lead to increased bleeding

A new study published today in the Journal of the American Medical Association (JAMA) has found that taking aspirin on a regular basis to prevent heart attacks and strokes, can lead to an increase risk of almost 50% in major bleeding episodes.

Blocking toxic-protein production in ALS

Patients with ALS frequently have a string of repeated DNA code in the cells of their brain, carrying hundreds to thousands of copies within the gene C9orf72. New research looks at what triggers these repeated sequences to eventually produce the toxic proteins that are associated with ALS, frontotemporal dementia, and other neurodegenerative diseases in patients carrying the C9orf72 mutation, the most common cause of inherited ALS. The work finds that neuronal excitation and stress trigger the protein production in cells, and reveals that targeting this stress response with a known drug could reduce toxic protein production.

Health literacy linked to blood pressure medication adherence among Hispanics

Good health literacy is associated with better adherence to blood pressure medications among Hispanic individuals with high blood pressure, finds a study by NYU Rory Meyers College of Nursing and Columbia University School of Nursing. However, the majority of this population lacks health literary and has poor adherence to their medications.

To halt malaria transmission, more research focused on human behavior needed

Wherever possible, researchers should not just focus on mosquito behavior when working to eliminate malaria, but must also consider how humans behave at night when the risk of being bitten by an infected mosquito is highest, new findings from the Johns Hopkins Center for Communication Programs (CCP) suggest. CCP is based at the Johns Hopkins Bloomberg School of Public Health.

Study offers promise for preventing necrotizing enterocolitis in preemies

Researchers at Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago, and colleagues, discovered a promising direction toward understanding the development of necrotizing enterocolitis (NEC), a devastating intestinal disease commonly affecting premature infants, in order to treat it. Studying the early cellular events leading to NEC in a mouse model, they found that activation of a key protein (transcription factor NF-κB), which responds to stimuli like bacterial products, triggers inflammation in the intestine prior to the presence of intestinal injury. Blocking NF-κB activity prevented recruitment of bone marrow-derived monocytes (a type of white blood cells) into the intestine and their subsequent differentiation into macrophages (immune cells involved in the inflammatory response but also tissue damage when unregulated). This process decreased the development of NEC. Their findings were published in the American Journal of Pathology.

Breastmilk sugars differ in pregnant women on probiotics

The complex sugars found in human breastmilk, long believed to be fixed in their composition, may change in women who are taking probiotics, according to new research from the University of Rochester Medical Center (URMC).

It was the seventh leading cause of death in 2016, according to the World Health Organization. The Diabetes Atlas of the International Diabetes Federation (IDF) predicts that by 2045, some 629 million people (aged 20-79) will have diabetes if no action is taken. The IDF also notes that in high-income countries, about 87 percent to 91 percent of all people with diabetes are estimated to have type 2 diabetes, compared with 7 percent to 12 percent who are estimated to have type 1 diabetes. Considering the fact that type 2 diabetes is rising across all regions in the world and that the effectiveness of existing therapies varies significantly between individuals, scientists are increasingly focusing on targeted treatments.

Investigators close in on best treatment guidelines for critical limb ischemia

Critical limb ischemia (CLI), a manifestation of peripheral arterial disease, is a debilitating and increasingly common disease that puts patients at a high risk for leg amputation, cardiovascular complications, and death. A new report in the Journal of Vascular Surgery chronicles a multi-site randomized controlled trial that seeks to compare treatment efficacy, functional outcomes, cost effectiveness, and quality of life for 2,100 patients suffering from the condition.

Significant disparities between educational groups in smoking during pregnancy

With the help of a multidisciplinary register and questionnaire study, Finnish researchers at the University of Turku showed that both the educational level and its occupational orientation predict the mother's smoking during early pregnancy.

Resisting the exploitation of black women's reproductive labor in the United States

In "Milk Money: Race, Gender, and Breast Milk 'Donation,'" published in Signs: Journal of Women in Culture and Society, Laura Harrison demonstrates the exploitative, racially charged nature of Milk Money, a failed pilot program by the Mothers Milk Cooperative and their business partner, Medolac Laboratories. The program, which was a Clinton Global Initiative Foundation "Commitment to Action," targeted African American mothers in Detroit to sell their breast milk at one dollar per ounce to Medolac, who would then process it and sell it at a 600 percent markup.

Fewer than half of adults and youth with type 1 diabetes in the US achieve treatment goals

A new study has shown that only a minority of patients in the U.S. with type 1 diabetes (T1D) achieve target levels of hemoglobin A1c, a measure of blood glucose management over time. In fact HbA1c levels have increased in young adults and teens in 2016-2018 compared to 2010-2012 according to the study published in Diabetes Technology & Therapeutics (DTT).

Older caregivers report worse well-being when providing minimal assistance

Providing less than an hour of help to an elderly person can take a surprising emotional toll on older caregivers, says a University of Michigan researcher.

The diversity of rural African populations extends to their microbiomes

Our microbiome, the complex community of bacteria, fungi, parasites, and other microorganisms in and on our bodies, reflects the way we live. If we own a pet, we likely share microbes with them. If we eat meat, the microbiome in our intestines may look different from that of a vegan.

Antarctic krill population contracts southward as polar oceans warm

The population of Antarctic krill, the favourite food of many whales, penguins, fish and seals, shifted southward during a recent period of warming in their key habitat, new research shows.

Small trees are among the oldest in Congolese rainforest

Forest giants have long been considered the oldest trees in tropical forests, but new research shows small trees can also be very old, and can even grow older than the big ones.

How sex pheromones diversify: Lessons from yeast

Many organisms including insects, amphibians and yeasts use sex pheromones for attracting individuals of the opposite sex, but what happens to sex pheromones as new species emerge? New research publishing January 22 in the open-access journal PLOS Biology from Taisuke Seike and Hironori Niki at the National Institute of Genetics, Japan and Chikashi Shimoda at Osaka City University, Japan studies sex pheromones in the fission yeast Schizosaccharomyces pombe, revealing an "asymmetric" pheromone recognition system in which one pheromone operates extremely stringently whereas the other pheromone is free to undergo a certain degree of diversification, perhaps leading to a first step towards speciation.

Scientists demonstrate effective strategies for safeguarding CRISPR gene-drive experiments

Researchers have demonstrated for the first time how two molecular strategies can safeguard CRISPR gene-drive experiments in the lab, according to a study published today in eLife.

Long-read DNA analysis can give rise to errors, experts warn

Advanced technologies that read long strings of DNA can produce flawed data that could affect genetic studies, research suggests.

Researchers uncover migratory schedule of swallows, new study

Each year, migratory birds journey from their breeding grounds to their wintering grounds, making pit stops along the way.

Bird beaks did not adapt to food types as previously thought, study suggests

A study, led by the University of Bristol, has shed some new light on how the beaks of birds have adapted over time.

Trout, salamander populations quickly bounce back from severe drought conditions

Populations of coastal cutthroat trout and coastal giant salamanders in the Pacific Northwest show the ability to rebound quickly from drought conditions, new research by Oregon State University suggests.

Possible Oahu populations offer new hope for Hawaiian seabirds

The two seabird species unique to Hawaii, Newell's Shearwaters and Hawaiian Petrels, are the focus of major conservation efforts—at risk from habitat degradation, invasive predators, and other threats, their populations plummeted 94% and 78% respectively between 1993 and 2013. However, a new study in The Condor: Ornithological Applications offers hope of previously undetected colonies of these birds on the island of Oahu, from which they were believed to have vanished by the late 1700s.

Armed with affection, octogenarian is an 'octopus whisperer'

Wilson Menashi palmed a squid in his left hand and extended his arm into an aquarium tank, watching as a giant Pacific octopus stretched out arms to greet him like a friend.

Why we don't know if Irukandji jellyfish are moving south

Reports that Irukandji jellyfish might be moving south may be panicking people unnecessarily. It's almost impossible to tell where the tiny jellyfish are along our coast, but that could change with new technology that can "sweep" the ocean for traces of DNA.

Otago researcher contributes piece to the puzzle of baleen whales' evolution

An Otago researcher has added another piece to the puzzle of the evolution of modern baleen whales with a world-first study examining the teeth and enamel of baleen whales' ancestors.

Plants blink: Proceeding with caution in sunlight

Plants have control mechanisms that resemble those in human senses. According to a new Weizmann Institute of Science study, plants adjust photosynthesis to rapid light changes using a sophisticated sensing system, much in the way that the human eye responds to variations in light intensity. This sensory-like regulation operates at low light intensities, when the photosynthesis machinery is most efficient but also most vulnerable to sudden light increases.

Study looks at ranger motivation in dangerous African park

A new study by WCS looks at the job satisfaction of front line conservation rangers working in challenging conditions at a national park in the eastern Democratic Republic of the Congo (DRC) and identifies ways to improve motivation to make them more effective at enforcing the law.

Without habitat management, small land parcels do not protect birds

Designating relatively small parcels of land as protected areas for wildlife with no habitat management—which has frequently been done in urban-suburban locales around the world—likely does not benefit declining songbird species, according to a team of researchers who studied a long-protected northeastern virgin forest plot.

Researchers identify gene essential for plants to survive

Phenylalanine amino acid must be included in the human diet, but it is also essential for plants, determining many of their characteristics, such as the colour and scent of flowers, healing powers and antioxidant properties, and the strength of wood. A team of researchers from the UMA has now demonstrated that ADT2 gene is essential for plants to produce phenylalanine, conditioning their survival.

Emerging significance of gammaherpesvirus and morbillivirus infections in cats

Emerging infectious diseases comprise a substantial fraction of important human infections, with potentially devastating global health and economic impacts. A 2008 paper in Nature described the emergence of no fewer than 335 infectious diseases in the global human population between 1940 and 2004. In the veterinary field, just as in the medical field, advanced molecular techniques and sophisticated computer-based algorithms for genetic sequence assembly and analysis have revolutionised infectious disease research. They have also raised important questions, as the potential pathogenic role of novel viruses can be difficult to determine.
