This microscopic device is one of three that together separate out individual HIV-infected immune cells from blood samples and trap their genetic contents in droplets for analysis. Iain Clark and Adam Abate Curing HIV infections remains one of the most formidable challenges in biomedicine, in part because cells...
The Environmental Protection Agency says it will conduct helicopter overflights to look for methane "super emitters" in the nation's largest oil and gas producing region.
Chinese investments in research and development (R&D) have burgeoned since the turn of the century, increasing more than tenfold in absolute terms since 2000 and reaching a high of 2.4 percent of GDP in 2020. As the world's second biggest spender on R&D after the United States, China is certainly a force to be reckoned with on the global innovation landscape. Its fresh push toward innovation-led...
Researchers are studying the way warming water temperatures will impact the Great Lakes region. Their work shows that small differences in lake surface temperatures can have a big impact on summer climate and can fuel extreme weather—crucial information.
As satellites crawl across the sky, they reflect light from the sun back down to Earth, especially during the first few hours after sunset and the first few hours before sunrise. As more companies launch networks of satellites into low-Earth orbit, a clear view of the night sky is becoming rarer. Astronomers, in particular, are trying to find ways to adapt.
Less than two years after shocking the science world with the discovery of a material capable of room-temperature superconductivity, a team of UNLV physicists has upped the ante once again by reproducing the feat at the lowest pressure ever recorded.
The traditional idea of symbiosis—long-term interactions between two organisms—is that the participants mutually benefit each other. However, researchers have debated whether the interests of the symbionts always line up with the hosts they inhabit, or whether genes that benefit symbionts might come at the expense of their hosts. A new study investigates this question through genomic...
Bioscientists from Durham University, UK and Senckenberg Biodiversity and Climate Research Centre, Germany have predicted in their latest research that bird communities will change worldwide in 2080 due to climate change, largely as result of shifting their ranges.
The northern and central Great Barrier Reef have recorded their highest amount of coral cover since the Australian Institute of Marine Science (AIMS) began monitoring 36 years ago.
The northern and central Great Barrier Reef have recorded their highest amount of coral cover since the Australian Institute of Marine Science (AIMS) began monitoring 36 years ago. However, average coral cover in the southern region decreased due to ongoing crown-of-thorns starfish outbreaks. While the Reef experienced its fourth major bleaching event in the past seven years this year, it didn't...
A Purdue University chemical engineer has improved upon traditional methods to produce off-the-shelf human immune cells that show strong antitumor activity, according to a new article.
Students have completed a comprehensive brightness study to characterize mega-constellation satellites cluttering the skies.
Researchers report changes caused by reductive stress to describe changes in the proteome of heart cells in mice, disclosing a likely proteome signature for reductive stress cardiomyopathy. A proteome is the complement of proteins expressed in a cell or tissue. One in six heart failure patients shows reductive stress.
Researchers from Western University have verified the authenticity of a South American tsantsa (shrunken head) as human remains, an important step in the global effort toward decolonization and preserving and understanding Indigenous history.
Physicists are (temporarily) augmenting reality to crack the code of quantum systems.
University of California, Irvine researchers have developed a COVID-19 test that detects and identifies specific SARS-CoV-2 variants with 100% accuracy. In a study, the RNA-encoded viral nucleic acid analytic reporter correctly determined the Alpha, Gamma, Delta, Epsilon and Omicron genetic mutations in nasopharyngeal clinical samples. This ability could enable healthcare providers to make...
NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will share a ride to space with NASA's Jet Propulsion Laboratory's Spectro-Photometer for the History of the Universe, Epoch of Re-ionization, and Ices Explorer (SPHEREx) mission. The missions will launch no earlier than April 2025 on a SpaceX Falcon 9.
It's sunburn season. Many of us have experienced the pain and peeling that comes from unprotected time in the sun, but we may not focus on a remarkable and vital part of the process: the regeneration of skin as the damaged tissue is replaced with new.
Following the successful launch of NASA's Lucy spacecraft on Oct. 16, 2021, a group of engineers huddled around a long conference table in Titusville, Florida. Lucy was mere hours into its 12-year flight, but an unexpected challenge had surfaced for the first-ever Trojan asteroids mission.
The outer layer of skin, the epidermis, is constantly turning over to replace dead or damaged cells throughout our lifetime. Skin stem cells need to continuously make decisions: either make more copies of themselves (self-renewal) or switch their fate towards differentiation. The molecular mechanisms controlling this process remain poorly understood. Now a research team has identified a molecular...
Why do some people with amyloid plaques in their brains associated with Alzheimer's disease show no signs of the disease, while others with the same amount of plaque have clear memory and thinking problems? Researchers looked at genetic and life course factors that may help create a 'cognitive reserve' that provides a buffer against the disease.
