Phys.org / Antarctic ice melt may fuel eruptions of hidden volcanoes
A slow climate feedback loop may be bubbling beneath Antarctica's vast ice sheet. The continent, divided east to west by the Transantarctic Mountains, includes volcanic giants such as Mount Erebus and its iconic lava lake. ...
Phys.org / Past climate shifts altered Southern Ocean currents and carbon exchange: Study warns it may be happening again
Human-induced climate change is causing shifts in the world's largest ocean current and westerly wind systems also seen during periods of ice age and warmer intervals in Earth's history, researchers claim.
Phys.org / Scientists create vast library of compounds to target disease proteins
Over the past two decades, large genetic studies have linked tens of thousands of DNA variants to thousands of human traits and diseases. Yet, correcting the effects of those variants to treat disease has been hampered in ...
Phys.org / Hidden 'shapes' within plasma beams may boost next-generation space rockets
Go faster, farther, more efficiently. That's the goal driving spacecraft propulsion engineers like Chen Cui, a new assistant professor at the University of Virginia School of Engineering and Applied Science. Cui is exploring ...
Phys.org / Newly discovered mechanism triggers immune response in cells with damaged DNA
A research team from the University of California, Irvine has revealed a previously unknown mechanism that triggers an inflammatory immune response in cells when their DNA is damaged. This discovery deepens the understanding ...
Phys.org / Virtual chemistry synthesizes 25 variations of a plant compound that could treat brain diseases
Among the hundreds of thousands of chemical compounds produced by plants, some may hold the key to treating human ailments and diseases. But recreating these complex, naturally occurring molecules in the lab often requires ...
Phys.org / Scientists reveal CO₂'s fundamental role in ancient climate shifts
Researchers from the University of St Andrews have shed new light on the fundamental role played by carbon dioxide (CO2) in Earth's geological warming and cooling.
Phys.org / Zinc deprivation reveals vulnerability in resistant bacteria, reviving old antibiotics
Researchers at McMaster University have discovered a critical vulnerability in drug-resistant bacteria: zinc—or a lack thereof.
Phys.org / Newly discovered 'kiss and capture' mechanism explains the formation of Pluto and its largest moon
Billions of years ago, in the frigid outer reaches of our solar system, two icy worlds collided. Rather than destroying each other in a cosmic catastrophe, they spun together like a celestial snowman, finally separating while ...
Phys.org / Hornwort genomes provide clues on how plants conquered the land
Over 450 million years ago, plants began the epic transition from water to dry land. Among the first pioneers were the ancestors of humble hornworts, a group of small, unassuming plants that have persisted to this day. New ...
Phys.org / Laser technique uncovers how titanium's electron behavior influences its physical properties
A research team at Yokohama National University has developed a way to study how the orientation and behavior of electrons in titanium influence its physical characteristics. Their findings, published in Communications Physics ...
Phys.org / Electron microscopy captures enzyme step in antibiotic production
Nonribosomal peptide synthetase (NRPS) enzymes are essential in creating important medications, such as penicillin and cyclosporine. This is done through a multi-step process where the enzymes activate amino acid building ...
