Waiting in Line: Why Six Feet of Social Distancing May Not Be Enough
Study, led by undergraduate physics majors at UMass Amherst and researchers at University of Cadiz, sharpens our understanding of how airborne-communicable diseases travel
AMHERST, Mass. – We all remember the advice frequently repeated during the COVID pandemic: maintain six feet of distance from every other human when waiting in a line to avoid transmitting the virus. While reasonable, the advice did not take into account the complicated fluid dynamics governing how the airborne particles ...
Toxic well water will affect household pets first, new study finds
2025-08-06
Dogs drink water wherever they happen to find it — a puddle, a pond, a toilet. But the stuff in their actual water bowls almost always comes from the same tap their owners use. When that water is contaminated, both dogs and humans may suffer.
The risk is especially high for the 15 million American households that rely on private wells, according to a new Virginia Tech study in the journal PLOS Water. In dog drinking water sampled from wells across the country, 64 percent contained excessive levels of at least one potentially toxic heavy metal, such as lead, iron, sulfur, or arsenic.

Some young suns align with their planet-forming disks, others are born tilted
2025-08-06
(Santa Barbara, Calif) — Researchers at UC Santa Barbara, The University of Texas at Austin, Yale University and National Taiwan Normal University have found that a fair number of sun-like stars emerge with their rotational axis tilted with respect to their protoplanetary disks, the clouds of gas and dust from which solar systems are born.
“All young stars have these discs, but we’ve known little about their orientations with respect to the spin axis of the host stars,” said UCSB associate physics professor Brendan Bowler, who studies how planets form and evolve through their orbits and atmospheres, and is senior author of a study in ...
Neighbors matter: Community cohesion boosts disaster resilience, Texas A&M study finds
2025-08-06
A study from the Texas A&M University School of Public Health sheds new light on the relationship between community cohesion prior to a natural disaster and resilience after one, with possible policy applications for public health and emergency preparedness practitioners.
“Recent events have reminded us that resilience isn’t just about bricks and budgets,” said community health expert Garett T. Sansom, who led the study. “In part, it’s also about bonds between neighbors.”
Until now, he added, little has been known about the mechanisms ...

Scrambled RNA nudges millions of people towards type-2 diabetes
2025-08-06
Mutations in a single gene, HNF1A, are known to cause MODY3, a rare, early onset form of diabetes. Smaller scale mutations in the very same gene are also common and quietly nudge millions of people toward type-2 diabetes. A study published today in Cell Metabolism reveals why.
Researchers at the Centre for Genomic Regulation (CRG) in Barcelona show it’s fundamentally a problem of insulin-producing β‑cells. Using mouse models, they switched HNF1A off in different tissues and cell types including the liver, the gut and both α and β‑cells in the pancreas, ...

Replacing brain immune cells in mice slows neurodegeneration in Stanford Medicine study
2025-08-06
Tay-Sachs and Sandhoff diseases, genetic disorders affecting the brain, have no effective treatment and are typically fatal within the first years of life. Scientists have reasoned that replacing the affected cells with those that are genetically healthy could slow or halt the neural degeneration that causes the symptoms. But the approach has been plagued with problems, including poor engraftment in the brain and a graft-versus-host response in which transplanted cells attack healthy tissue.
Now researchers at Stanford Medicine have developed a way to replace more than half of the most severely affected cells, called microglia, with ...

Changes to El Niño occurrence causing widespread tropical insect and spider declines
2025-08-06
Arthropods, including insects and spiders, make up the vast majority of animal species on the planet.
Despite their small size they are irreplaceable contributors to the health of natural habitats, as well as vital food sources for birds and other larger animals.
But, arthropods may be declining globally. There is some evidence to support reduced numbers of species in temperate regions of the Northen Hemisphere. In the tropics, however, evidence for arthropod declines has so far been limited.
A recent international collaboration of scientists has attempted to find this missing evidence, with the findings published in Nature.
The ...
Nanophotonics: An ultrafast light switch
2025-08-06
In nanophotonics, tiny structures are used to control light at the nanoscale and render it useful for technological applications. A key element here is optical resonators, which trap and amplify light of a certain color (wavelength). Previous methods of controlling these resonances were more like a dimmer switch: You could weaken the resonance or slightly shift its color. However, genuine on-and-off switching was not possible, as the resonators always remain fundamentally coupled with the light.
A team led by Andreas Tittl, Professor of Experimental Physics at LMU, has now achieved precisely this breakthrough together with partners from Monash ...

2025-08-06
WASHINGTON (August 6, 2025) — Using portable high-efficiency particulate air (HEPA) purifiers at home can significantly lower systolic blood pressure (SBP) in adults with elevated baseline readings — even in areas with relatively low overall air pollution levels, according to a study published today in JACC, the flagship journal of the American College of Cardiology.
Particulate matter (PM) is a major contributor to air pollution and is strongly associated with cardiovascular disease (CVD). People ...
Effective therapy for MDS is vastly underused, especially in female and non-white patients
2025-08-06
(WASHINGTON – August 6, 2025) – Most patients with high-risk myelodysplastic syndromes (MDS) do not receive guideline-recommended treatment with hypomethylating agents (HMAs), according to results published in Blood Neoplasia. The findings suggest that underuse of these drugs may help explain why MDS outcomes have not improved over the past two decades since these life-extending medications became available.
The study is the largest analysis of MDS treatment patterns in the United States to date and the most comprehensive study of real-world use of HMAs, which are highly effective in improving outcomes. HMAs are the best available ...
Genetic rescue of endangered species may risk bad mutations slipping through
2025-08-06
COLUMBUS, Ohio – The established conservation practice of relocating animals from large, genetically diverse populations to small communities of inbred endangered species may risk introducing more damaging than beneficial gene variants into the threatened group, a new study suggests.
Analysis of genomes of Eastern massasauga rattlesnakes showed that, by the numbers, more deleterious than adaptation-enabling mutations were present in the more genetically diverse donor animals selected in a hypothetical scenario to join a small, isolated population.
Because donor relocation, known as ...
