Phys.org / Carbon-free ferrocene alternative opens up new possibilities for future materials
About 75 years ago, scientists accidentally synthesized a compound called ferrocene in which the iron (Fe) atom is sandwiched between two C5H5 rings—(C5H5)Fe(C5H5). This compound opened up a new era in transition metal chemistry, ...
Phys.org / 'Indian Niño' drove record heat in 2023 and 2024, new study finds
In 2023 and 2024, Earth's average global surface temperature spiked nearly 0.3 degrees Celsius above what was already expected from climate change. Each year was declared the hottest on record and coincided with deadly wildfires, ...
Phys.org / Bacterial protein map could open new path against drug-resistant infections
La Trobe scientists have made a pivotal discovery in the fight against dangerous drug-resistant bacteria, as the University launches a major research initiative focused on new ways to target antimicrobial resistance (AMR). ...
Phys.org / 'Not just hot water': Marine heat waves can create toxic relationship between seagrasses and microbes
Heat stress from marine heat waves can create a toxic relationship between seagrasses and a hidden ecosystem of bacteria, transforming a previously beneficial co-existence between marine plants and microbes into a harmful ...
Phys.org / Deforestation may push Amazon degradation threshold below 2°C warming
Around two-thirds of the Amazon rainforest could shift into degraded forest or savanna-like ecosystems at 1.5–1.9°C of global warming if deforestation increases to roughly 22–28% of the Amazon, according to a new study from ...
Phys.org / The lost koala: New fossil species was hiding in plain sight for 100 years
In 2024, the Western Australian Museum received a donation. It was a koala skull collected from Moondyne Cave in Margaret River by Lindsay Hatcher, an avid caver. There was something a bit odd about this skull, and we were ...
Phys.org / Freshwater mussel protein offers new source of inspiration for medical-grade glues
Researchers at the University of Toronto have identified a protein from the quagga mussel that can stick to surfaces underwater, even though it lacks a chemical feature long thought to be essential for this kind of adhesion. ...
Phys.org / 'Atomic snapshots' of proofreading enzyme could lead to better COVID-19 drugs
The closest-ever detailed look at a key enzyme inside the virus that causes COVID-19 could lead to more effective treatment of the disease. Nucleotide analogs are a common type of antiviral medication that mimic the genetic ...
Phys.org / On the ground or in the atmosphere? Swarm satellites help characterize and pinpoint destructive events
When solar storms strike Earth, they can disrupt power grids, rail systems, satellites, and even marine life. These effects arise because solar wind and geomagnetic activity disturb the magnetosphere–ionosphere system, generating ...
Phys.org / Federal grant terminations disproportionately impact minority scientists, study finds
Researchers from University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science have found that recent federal grant terminations targeting research on health equity and gender identity ...
Phys.org / Indigenous Andeans have a digestive superpower—and it may be linked to potatoes
Indigenous people of the Andes were the first to domesticate the potato, making the starch-rich crop a dietary staple for this high-altitude population long before it spread to the rest of the world. Today, their descendants ...
Phys.org / Medieval jaw reveals Scotland's first known dental bridge made from 20-carat gold
Without good dental care, teeth tend to suffer. An abundance of archaeological evidence has shown that poor oral health was common throughout history. And unsurprisingly, there have been many attempts at dental restoration ...
