Permian marine mass extinction linked to volcanism-induced anoxia
Mass extinctions are rapid global decreases in Earth's biodiversity, with five key events identified over the planet's history, arguably the most famous of which occurred ~66 million years ago during the Cretaceous, which brought the rein of dinosaur.....»»

Wolves" return has had only small impact on deer populations in Washington state, study shows
Humans drove wolves to extinction in Washington state around the 1930s. Thanks to conservation efforts, by about 80 years later, wolves had returned—crossing first from the Canadian border into Washington around 2008 and later entering the state fr.....»»
Brazil needs a new approach to measure climate migration
Devastating floods led to more than 175 deaths and 423,000 people displaced in the southern Brazilian state of Rio Grande do Sul in May. It was the state's worst natural catastrophe in almost a century, but Brazil is no stranger to mass population mo.....»»

"Sacrifice" of virus data clears the path to open a disease discovery pipeline
Tens of millions of still-unknown or misunderstood viruses can cause diseases—including new pandemics—and affect the health of valuable terrestrial and marine environments......»»
Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
As ocean surfaces acidify, a deep-sea acidic zone is expanding, and marine habitats are being squeezed
In the deepest parts of the ocean, below 4,000 meters, the combination of high pressure and low temperature creates conditions that dissolve calcium carbonate, the material marine animals use to make their shells......»»
TSMC gearing up for iPhone 17 A19 chip production with 2-nanometer test
Apple's chip partner is about to start trial production of chips using a 2-nanometer fabrication process, ahead of making the A19 chip destined for the iPhone 17.TSMC continues to be Apple's chip partner. Since 2022, TSMC has been planning to mass pr.....»»
First local extinction due to sea level rise identified in the US
The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country......»»
Restored oyster sanctuaries host more marine life despite parasites, biologists discover
In the campaign to restore Chesapeake Bay, oyster sanctuaries rank among the most hotly contested strategies. But new research suggests these no-harvest areas are working, and not only for the oysters......»»
Super-resolution machining of single crystalline sapphire by femtosecond laser-induced, plasma-assisted ablation

Features of H5N1 influenza viruses in dairy cows may facilitate infection, transmission in mammals
A series of experiments with highly pathogenic H5N1 avian influenza (HPAI H5N1) viruses circulating in infected U.S. dairy cattle found that viruses derived from lactating dairy cattle induced severe disease in mice and ferrets when administered via.....»»
Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change

Researchers predict new phase in neutron stars that favors "nuclear pasta"
Neutron stars are extreme and mysterious objects that astrophysicists cannot see inside. With a radius of around 12 kilometers, they can have more than twice the mass of the sun. The matter in them is packed up to five times as densely as in an atomi.....»»
We mapped the entire bilby genome—and now we can use poo to save Australia"s "Easter bunny" from extinction
Commonly known as Australia's "Easter bunny" due to its large ears and hopping movement, the greater bilby (Macrotis lagotis) is the last of its kind. Today we published its reference genome—all 3.66 billion pieces of it......»»
Researchers reveal how plants protect themselves from viral infection by regulating deacetylation
In a paper published in Science Bulletin, a team of Chinese scientists demonstrated that TaSRT2 recognized viral protein P153 and induced wheat resistance to CWMV through inhibition of the TaSRT2-mediated deacetylation of H3K9ac and H3K79ac, which ev.....»»

Research finds humpbacks were happier during pandemic pause
University of Queensland-led research has found migrating humpback whales off Australia's east coast became less stressed over the first year of the COVID-19 pandemic. The research paper is published in Marine Environmental Research......»»
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly,.....»»
