Life’s chemistry may begin in the cold darkness of space

Scientists at Aarhus University have overturned a long-standing assumption about how life’s essential ingredients emerge. New experiments show that the basic components needed to build proteins can form naturally in space, a finding that increases the likelihood that life could exist elsewhere in the universe. The research was carried out…

Walking sharks break the rules of reproduction

Scientists at James Cook University have uncovered a striking biological surprise. Epaulette sharks can reproduce and lay eggs without showing any measurable increase in energy use. The finding challenges long-standing assumptions about how costly reproduction is for animals. The discovery comes from new research by JCU’s shark physiology team, led…

Ritrovato a Milano il 14enne scomparso da 9 giorni – Notizie – Ansa.it

È stato trovato a Milano, in buone condizioni, il 14enne di San Giovanni Lupatoto di cui si erano perse le tracce il 12 gennaio. Lo ha riferito il sindaco della città veronese, Attilio Gastaldello.    Il quattordicenne rintracciato stamani dopo nove giorni di assenza, è stato scoperto dagli agenti della…

Spacecraft captures the “magnetic avalanche” that triggers giant solar explosions

Much like a snow avalanche that starts with a small shift before cascading downhill, new observations show that solar flares begin with subtle magnetic disturbances that rapidly intensify. Scientists using the European Space Agency (ESA) led Solar Orbiter spacecraft discovered that these early changes can quickly grow into violent eruptions,…

This new building material pulls carbon out of the air

Researchers at Worcester Polytechnic Institute (WPI) have developed a new building material that removes more carbon from the atmosphere than it produces. The advance, reported in the high-impact journal Matter, describes a material called enzymatic structural material (ESM). It is designed to be strong, long-lasting, and recyclable, while requiring far…

The human brain may work more like AI than anyone expected

A new study suggests that the human brain understands spoken language through a stepwise process that closely resembles how advanced AI language models operate. By recording brain activity from people listening to a spoken story, researchers found that later stages of brain responses match deeper layers of AI systems, especially…

Tiny doses of THC show big benefits for HIV treatment

New research from Texas Biomedical Research Institute suggests that long-term use of very small amounts of THC may reduce inflammation and ease several harmful effects linked to HIV and antiretroviral therapy (ART). THC, short for tetrahydrocannabinol, is the primary active compound found in cannabis. In this preclinical research, scientists used…

The world’s mountains are warming faster than anyone expected

Mountains around the world are warming more quickly than nearby lowland areas, according to a major global review, and the impacts could be severe for billions of people who live in or rely on these regions. Researchers warn that climate shifts at higher elevations are unfolding faster and with greater…

Stanford scientists found a way to regrow cartilage and stop arthritis

A study led by Stanford Medicine researchers has found that an injection blocking a protein linked to aging can reverse the natural loss of knee cartilage in older mice. The same treatment also stopped arthritis from developing after knee injuries that resemble ACL tears, which are common among athletes and…

Patients tried everything for depression then this implant changed their lives

About one in five adults in the United States will experience major depression at some point in their lives. Many people improve after trying a few treatments, but for as many as one-third of patients, standard antidepressants or psychotherapy do not provide enough relief. This condition, known as treatment-resistant depression,…
