A shapeshifting protein explains rabies’ deadly power
Researchers discovered how rabies virus exerts massive control over host cells with very few genes. A key viral protein changes shape and binds RNA, allowing it to infiltrate different cellular systems. This adaptability could explain the power of other deadly viruses,
130 species in Southern Ontario at risk of local extinction by 2050 if no new actions taken, study indicates
Southern Ontario is home to 133 at-risk species, 98% of which could be locally extinct in the next 25 years if the provincial government takes no action to protect them. But a new study from the University of British Columbia and World Wildlife Fund Canada has found that an
Ancient trees' inefficient photorespiration may have helped stabilize Earth's atmosphere during last ice age
Ancient trees may have played a key role in regulating Earth's climate during the last ice age—by 'breathing' less efficiently.
Are there different types of black holes? New method puts Einstein to the test
Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes at the center of the galaxy M87 and our Milky Way, published a few years ago by the Event Horizon Telescope (EHT) collaboration, broke new ground.
Microcompartment approach expands possibilities for studying viruses in the environment
A new method vastly improves on the existing approach for single-cell genetic sequencing, enabling scientists to read the genomes of individual cells and viral particles in the environment more quickly, efficiently, and cost-effectively.
Cleaner air may be accelerating warming by making clouds less reflective
Earth is reflecting less sunlight, and absorbing more heat, than it did several decades ago. Global warming is advancing faster than climate models predicted, with observed temperatures exceeding projections in 2023 and 2024. These trends have scientists scrambling to

How hops produce chiral α-bitter acids that give beer its signature taste
Hops are an essential ingredient in beer brewing and an important economic crop. The female flowers of hops are covered in tiny glandular trichomes that synthesize and store a variety of specialized metabolites, collectively defining the flavor and quality of beer. Terpenes
'Resilience Science Must-Knows': Report shows how decision-makers can manage global crises
As the world approaches critical tipping points, a comprehensive global scientific report shows that resilience—the ability to live and develop with change and crises—must now be placed at the heart of global decision-making.
Cockroaches are secretly poisoning indoor air
Cockroach infestations don’t just bring creepy crawlers, they fill homes with allergens and bacterial toxins that can trigger asthma and allergies. NC State researchers found that larger infestations meant higher toxin levels, especially from female roaches. When extermination
Scientists shocked to find E. coli spreads as fast as the swine flu
Researchers have, for the first time, estimated how quickly E. coli bacteria can spread between people — and one strain moves as fast as swine flu. Using genomic data from the UK and Norway, scientists modeled bacterial transmission rates and discovered key differences between
Tiny molecules could stop glaucoma before it blinds
Scientists at Mizzou have identified two small molecules, agmatine and thiamine, that could both reveal and fight glaucoma. Their research shows these compounds are lower in glaucoma patients, suggesting they may serve as early warning markers. Even better, they might help
Reframing aging as evolutionary success
In our modern society, aging tends to be something we ignore, and then try to avoid. Mainstream culture is geared toward the young, using the young to gauge trends and styles, and targeting their spending power. Meanwhile, the anti-aging industry is booming, with billions of

Biodiversity startups attract diverse investors but raise less capital than peers
Biodiversity startups, which are tackling challenges ranging from disappearing pollinators to vanishing coral reefs, raise less capital than other startups but attract a broader coalition of investors, according to a new analysis that used machine learning to sift through
Scientists uncover the secret triggers of ‘impossible’ earthquakes
Once considered geologically impossible, earthquakes in stable regions like Utah and Groningen can actually occur due to long-inactive faults that slowly “heal” and strengthen over millions of years. When reactivated—often by human activities—these faults release all that
