An international team of scientists, including UNLV astrophysicist Bing Zhang, reports in the July 26 issue of Nature a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen.
The Neolithic lifestyle, based on farming instead of hunting and gathering, emerged in the Near East around 12,000 years ago and contributed profoundly to the modern way of life.
Earth is truly unique among our Solar System’s planets. It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of life.
Researchers have found that dozens of viruses respond to quorum sensing or other chemical signals from bacteria.

Scientists at UT Southwestern Medical Center and Children’s Medical Center Dallas have discovered in mice how high cholesterol causes blood vessels to become inflamed, a necessary prerequisite for atherosclerosis – the “hardening of the arteries” responsible for most heart attacks and strokes. The findings, published in Nature Communications, could lead to new interventions to protect against cardiovascular diseases (CVD), the leading cause of death globally.
University of Miami Rosenstiel School researchers Daniel Suman and Claire B. Paris-Limouzy are co-authors of a recent journal article that outlines ways to achieve greater equity in ocean governance and science in the global tropics. And one of those ways is by allowing residents to have a say in policy making.
Reducing waste is one way to help combat hunger around the world, but stricter control over food loss and waste does not lead to better environmental outcomes, according to researchers at the University of California, Irvine and the University of Colorado Boulder. In a paper published recently in Nature Food, the scientists stress that curbing food spoilage increases the amount of produce in markets, which leads to lower costs.
In the face of existential dilemmas that are shared by all of humanity, including the consequences of inequality or climate change, it is crucial to understand the conditions leading to cooperation. A new game theory model developed at the Institute of Science and Technology Austria (ISTA) based on 192 stochastic games and on some elegant algebra finds that both cases – available information and the lack thereof – can lead to cooperative outcomes.
Water, water, everywhere – not in drops, but as steam. Scientists using NASA’s James Webb Space Telescope have discovered that thirsty planets in the PDS 70 system have access to a reservoir of water. Importantly, the water vapor was found within 100 million miles of the star – the region where terrestrial planets like Earth may be forming. (The Earth orbits 93 million miles from our Sun.)
In a study researchers at the Friedman School of Nutrition Science and Policy at Tufts University and the University of Nottingham Rights Lab calculated the risk of forced labor across all aspects of the U.S. food supply, excluding seafood.

Neuromorphic computers do not calculate using zeros and ones. They instead use physical phenomena to detect patterns in large data streams at blazing fast speed and in an extremely energy-efficient manner.
Uncontrollable movements, memory loss, mood changes, and forgetfulness. That are some of the symptoms of neurodegenerative diseases in which cells in the central nervous system stop working or die.
An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.
A Southwest Research Institute-led team has modeled the early impact history of Venus to explain how Earth’s sister planet has maintained a youthful surface despite lacking plate tectonics.
Researchers at the University of Illinois Chicago have identified a process by which enzymes can help prevent heart damage in chemotherapy patients
Over the last 30 years European breeding birds have shifted their range by, on average, 2.4km per year, according to new research.
Today's catalysts for removing unburnt methane from natural-gas engine emissions are either inefficient at low, start-up temperatures or break down at higher operating temperatures. A new single-atom catalyst solves both these problems and removes 90% of the methane.
Georgia Tech researchers are using aluminum foil to create batteries with higher energy density and greater stability. The team’s new battery system could enable electric vehicles to run longer on a single charge and would be cheaper to manufacture — all while having a positive impact on the environment.
Researchers find indicators while studying hundreds of donor samples
Researchers led by a team at the University of Wisconsin–Madison have created the first tool to map and visualize the areas where human settlements and nature meet on a global scale. The tool, which was part of a study recently published in Nature, could improve responses to environmental conflicts like wildfires, the spread of zoonotic diseases and loss of ecosystem biodiversity.
A set of nine scientific papers was released today in the Nature family of journals and the journal Cell Reports describing breakthroughs in creating an open framework for scientists to map the individual cells of the human body in two and three dimensions.

Scientists have demonstrated experimentally a long-theorized relationship between electron and nuclear motion in molecules, which could lead to the design of materials for solar cells, electronic displays and other applications that can make use of this powerful quantum phenomenon.
People who contract COVID-19 but never develop symptoms – the so-called super dodgers – may have a genetic ace up their sleeve. They’re more than twice as likely as those who become symptomatic to carry a specific gene variation that helps them obliterate the virus, according to a new study led by UC San Francisco researchers.
Researchers from Sandia National Laboratories and Texas A&M University announce the first observation of a self-healing metal. If harnessed, the newly discovered phenomenon could someday lead to engines, bridges and airplanes that reverse damage caused by wear and tear, making them safer and longer-lasting.

The research underscores the limitations of the health care system’s frequent reliance on broad self-reported race and ethnicity data to assess patients’ risk of developing disease, and the findings also support expanding genetic screening to more groups.
Halide perovskites have applications in solar energy, radiation detection, and potentially in thermal harvesting. Cesium lead bromide is among the simplest of lead halide perovskite materials (LHPs). New research examined structural instabilities and large atomic fluctuations that may affect LHPs’ optical and thermal properties. It found that the atomic vibrations (phonons) of bromine octahedrons have large amplitudes but cannot oscillate for long amounts of time. Instead, the vibrations are strongly damped.
Data scientists at the Icahn School of Medicine at Mount Sinai in New York and colleagues have created an artificial intelligence model that may more accurately predict which existing medicines, not currently classified as harmful, may in fact lead to congenital disabilities. The model, or “knowledge graph,” described in the July 17 issue of the Nature journal Communications Medicine, also has the potential to predict the involvement of pre-clinical compounds that may harm the developing fetus. The study is the first known of its kind to use knowledge graphs to integrate various data types to investigate the causes of congenital disabilities.
