Glitch in neutron star reveals its hidden secrets

Neutron stars are not only the most dense objects in the Universe, but they rotate very fast and regularly. Until they don't.

Dense gas detected in intercore bridges in the S235 star-forming region

Using the Nobeyama Radio Observatory (NRO), astronomers have investigated a massive star-forming region known as S235. The study resulted in detecting high-density gas in this region, which could be helpful in advancing the knowledge of star-formation mechanisms. The finding is detailed in a paper published August 2 on arXiv.org.

Virtual 'universe machine' sheds light on galaxy evolution

A new timeline of Earth's cataclysmic past

Welcome to the early solar system. Just after the planets formed more than 4.5 billion years ago, our cosmic neighborhood was a chaotic place. Waves of comets, asteroids and even proto-planets streamed toward the inner solar system, with some crashing into Earth on their way.

Amid protest, Hawaii astronomers lose observation time

Asteroids, including those that might slam into Earth. Clouds of gas and dust on the verge of forming stars. Planets orbiting stars other than our own.

Modeling a core collapse supernova

Stars greater than eight solar-masses end their lives spectacularly—as supernovae. These single-star supernovae are called core collapse supernovae because when their dense cores (at this stage composed primarily of iron) are no longer able to withstand the inward pressure of gravity they collapse inward before exploding. Core collapse supernovae with strong hydrogen emission lines are thought to result from the explosions of red supergiant stars, massive stars that have evolved beyond their principle hydrogen burning stage and grown in radius. Until recently, astronomers thought these stars were relatively quiescent until their final demise, but evidence has been accumulating that they actually experience strong mass loss before exploding. In some models, emission resulting when ejecta from the supernovae encounter these envelopes produces the observed variations in core collapse supernova.

New findings suggest that women with specific DNA characteristics in certain areas of the genome may live longer if they take aspirin before they are diagnosed with breast cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings point to the need for studies on the potential of aspirin to prevent or treat breast cancer in some individuals.

Alzheimer's disease destroys neurons that keep us awake

Researchers and caregivers have noted that excessive daytime napping can develop long before the memory problems associated with Alzheimer's disease begin to unfold. Prior studies have considered this excessive daytime napping to be compensation for poor nighttime sleep caused by Alzheimer's-related disruptions in sleep-promoting brain regions, while others have argued that the sleep problems themselves contribute to the progression of the disease. But now UC San Francisco scientists have provided a striking new biological explanation for this phenomenon, showing instead that Alzheimer's disease directly attacks brain regions responsible for wakefulness during the day.

Diarrhea-causing bacteria adapted to spread in hospitals

Scientists have discovered that the gut-infecting bacterium Clostridium difficile is evolving into two separate species, with one group highly adapted to spread in hospitals. Researchers at the Wellcome Sanger Institute, London School of Hygiene & Tropical Medicine and collaborators identified genetic changes in the newly-emerging species that allow it to thrive on the Western sugar-rich diet, evade common hospital disinfectants and spread easily. Able to cause debilitating diarrhoea, they estimated this emerging species started to appear thousands of years ago, and accounts for over two thirds of healthcare C. difficile infections.

Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures. But a University of California, Riverside, research team has identified alternate chemistry that could account for the various pathologies associated with the disease.

In first-of-its-kind study, researchers highlight hookah health hazards

Hookah waterpipe use has grown in popularity in recent years—1 in 5 college students in the U.S. and Europe have tried it—but the practice could be more dangerous than other forms of smoking, according to a first-of-its-kind study by researchers at the University of California, Irvine, published recently in Aerosol Science and Technology.

Poor fit between job demands, reasoning abilities associated with health conditions

Older workers whose reasoning abilities no longer allow them to meet the demands of their jobs may be more likely to develop chronic health conditions and retire early, which may not be ideal for the employee or employer, according to research published by the American Psychological Association.

Osteoporosis drugs linked to reduced risk of premature death

Two studies led by the Garvan Institute of Medical Research have revealed that nitrogen-bisphosphonates, drugs commonly prescribed for osteoporosis, reduced the risk of premature mortality by 34% in a cohort of over 6,000 individuals. This reduction in early mortality risk was significantly associated with a reduction in bone loss compared with no treatment.

Gut-brain connection helps explain how overeating leads to obesity

Eating extra servings typically shows up on the scale later, but how this happens has not been clear. A new study published today in the Journal of Clinical Investigation by a multi-institutional team led by researchers at Baylor College of Medicine reveals a previously unknown gut-brain connection that helps explain how those extra servings lead to weight gain.

Cultural factors affect Chinese Americans' health

Ancient pigs endured a complete genomic turnover after they arrived in Europe

New research led by Oxford University and Queen Mary University of London has resolved a pig paradox. Archaeological evidence has shown that pigs were domesticated in the Near East and as such, modern pigs should resemble Near Eastern wild boar. They do not. Instead, the genetic signatures of modern European domestic pigs resemble European wild boar.

Researchers grow Lokiarchaea in special tank over 12-year study

A team of researchers affiliated with several institutions in Japan has succeeded in cultivating samples of Lokiarchaea in a special tank in their lab. They have published a paper describing their work on the bioRxiv preprint server as they await publication.

Bacteria made to mimic cells, form communities

Rice University scientists have found a way to engineer a new kind of cell differentiation in bacteria, inspired by a naturally occurring process in stem cells.

An emerging view of RNA transcription and splicing

Cells often create compartments to control important biological functions. The nucleus is a prime example; surrounded by a membrane, it houses the genome. Yet cells also harbor enclosures that are not membrane-bound and more transient, like oil droplets in water. Over the past two years, these droplets (called "condensates") have become increasingly recognized as major players in controlling genes. Now, a team led by Whitehead Institute scientists helps expand this emerging picture with the discovery that condensates play a role in splicing, an essential activity that ensures the genetic code is prepared to be translated into protein. The researchers also reveal how a critical piece of cellular machinery moves between different condensates. The team's findings appear in the Aug. 7 online issue of Nature.

A novel method to characterize genes with high-precision in single cells

The analysis of gene products in cells is an important tool for diagnosing disease and the design of new active substances in biological and medical research. At Helmholtz Zentrum München, a method of targeted RNA sequencing (transcriptome analysis) has now been developed, which precisely detects the smallest amounts of gene transcripts in single cells. The method enables the identification and enrichment of individual selected molecules in a sample in order to investigate their cellular function. This makes it possible to selectively characterize genes in each cell with high precision. Their work has been published in Genome Biology.

Scientists warn of too many pink salmon in North Pacific

Biological oceanographer Sonia Batten experienced her lightbulb moment on the perils of too many salmon three years ago as she prepared a talk on the most important North Pacific seafood you'll never see on a plate—zooplankton.

A probiotic treatment for obesity?

Alterations in the gut microbiota—the microorganisms residing in the gastrointestinal tract—have been implicated in the development of obesity and other chronic diseases.

Maggots as recyclers and protein sources

Black soldier fly maggots provide a zero waste option for organic recycling, according to Jeff Tomberlin, Ph.D., professor in the department of entomology at Texas A&M University and director of EVO Conversion Systems, LLC.

Know garden pests before deciding on a path to control

You look around the garden and see aphids suck the life out of your rose buds, flea beetles chomp on the cauliflower and cabbage butterflies lay eggs that will turn into voracious caterpillars. What to do?

When naproxen breaks down, toads croak

A new study in Environmental Toxicology and Chemistry takes a harder look at the effects a common anti-inflammatory medication and its degradation products have on amphibians. There have been many studies that review the toxicity of naproxen, a common over-the-counter pain reliever, but none until now that have reviewed the effects it or its degradation products might have on amphibians.

Genomic research unravels mystery of invasive apple snails

Biologists from Hong Kong Baptist University (HKBU) have led a study to sequence and analyse the genomes of four apple snail species in the family Ampullariidae. The researchers discovered that the apple snails have evolved to become highly sensitive to environmental stimuli, digest cellulose (a major component of the plant cell wall), form hard calcareous eggshells and pack neurotoxins in eggs. The findings could facilitate the development of effective genetic control measures for these destructive crop-eating snails.

Scent brings all the songbirds to the yard

Chickadees can smell! That is the news from a study out of Lehigh University, the first to document naturally hybridizing songbirds' preference for the scent of their own species.

Artificial intelligence helps banana growers protect the world's favorite fruit

Artificial intelligence-powered tools are rapidly becoming more accessible, including for people in the more remote corners of the globe. This is good news for smallholder farmers, who can use handheld technologies to run their farms more efficiently, linking them to markets, extension workers, satellite images, and climate information. The technology is also becoming a first line of defense against crop diseases and pests that can potentially destroy their harvests.
