Phys.org / Farm mice study shows antibiotic resistance is an environmental problem, not just a medical one
Scientists analyzed the genomes of gut microorganisms from an extensive population of 875 wild house mice (Mus musculus) collected from farms in Germany. They searched for genes responsible for resistance to common antibiotics ...
Phys.org / Rescue mission is called off for NASA's aging Swift space telescope
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
Phys.org / Extreme rain shifts toward larger, less frequent storms across eastern US
Extreme precipitation events are among the most damaging natural disasters and a major concern in our changing climate. In the U.S., since 1980, the most destructive events alone have caused more than 2,800 deaths and $700 ...
Phys.org / Designing supramolecular therapies to cross the blood-brain barrier
A new Northwestern Medicine study has uncovered key molecular design principles that could help supramolecular therapeutics cross the blood-brain barrier, a major challenge for this novel approach to treating neurological ...
Phys.org / Snake bones with flint cuts show Mount Carmel settlers ate reptiles 15,000 years ago
Around 15,000 years ago, the way of life of human communities in the southern Levant underwent a fundamental change. Groups of hunter-gatherers, who until then had been nomadic, reduced their mobility and established small, ...
Phys.org / 100-million-year-old molecular 'bypasses' may have helped grasses dominate landscapes and agriculture
100 million years ago, long before human intervention, ancestors of grasses, including wheat, rice and maize, developed "bypasses" in chemical pathways used to create two critical compounds: lignin and starch. These more ...
Phys.org / Why social media algorithms send you posts you don't like
Do your social media accounts feed you content that reflects your core beliefs and guiding principles? Our new research published in the Proceedings of the National Academy of Sciences shows that the algorithms supplying ...

When the U.S. Food and Drug Administration (FDA) proposed banning menthol cigarettes and flavored cigars in 2022, nearly 250,000 public comments flooded in—a record response that led the Biden administration to delay a final ...
Phys.org / Clubbing may boost well-being for women in midlife
An online survey published in the journal Psychology of Music asked 136 women ages 40 and older about their experiences at electronic dance music (EDM) events. Nine in 10 respondents (91%) said clubbing contributes positively ...
Phys.org / From the lab to headlines: Why do some studies make the news while others don't?
When we read a news story about a new cancer treatment, an Alzheimer's breakthrough or an innovative technology, we rarely think about everything that happens behind the scenes before that information reaches newspapers, ...
Phys.org / Illuminating the limits of the international unit of light, the candela
The candela, the international unit of light in use for almost a century, forms the basis of photometry. According to a new study, measurements derived from it systematically misjudge the brightness of colored light sources ...
Phys.org / How sex sheds evolutionary baggage
Why is there sex—or, more precisely, sexual reproduction? If you're an evolutionary biologist, the answer isn't obvious. Sexual reproduction is biologically costly, requiring not only competition for mates but also the creation ...
