Phys.org / How evolution can make cells smaller without slowing down their growth
A new study led by Marco Fumasoni, principal investigator at Fundação GIMM, shows that evolution can substantially reduce cell size without significantly compromising cells' ability to grow. The work, carried out in yeast ...
Phys.org / From 718 options to one standout, catalyst screening method reveals durable RuO₂ candidate
Why settle for a trial-and-error approach, reviewing an almost endless number of combinations, when you can systematically narrow the list to something more manageable using established data and knowledge?
Phys.org / Oddball exoplanet challenges what it means to be a hot Jupiter
New research led by a scientist at IPAC—a science and data center for astrophysics and planetary science at Caltech—studying the hot Jupiter CoRoT-2 b has settled on one of the three leading hypotheses explaining why its ...
Phys.org / Frozen Greenland middens preserve 4,500 years of farms, seal hunts and toilets
Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the 10th and 15th centuries, and early modern Danes since 1721. All ...
Phys.org / Fungi help lock carbon into Arctic fjord sediments
Arctic fjords are among the most efficient natural systems for absorbing and storing carbon long term. However, as the Arctic is warming about four times faster than the global average, fjord ecosystems are changing rapidly. ...
Phys.org / New heat-regulating fabric feels fluffy like cotton—but doesn't get wet
Once cotton gets wet, it pulls heat from your body. This is helpful when you're exercising or outside on a hot day, but dangerous in the bitter cold. Now, researchers reporting in ACS Energy Letters have created an ultralight ...
Phys.org / Bringing ancient light-sensing proteins back to life
Resurrecting dinosaurs using DNA retrieved from a mosquito trapped in amber is a great movie plot, though it's less likely to happen in the real world. However, researchers have been trying to unlock the secrets behind the ...
Phys.org / Reversible chirality switching in MoS₂ generates spin currents without magnets
A newly developed method allows researchers to dynamically switch chirality—a particular lack of mirror symmetry—to generate spin currents in semiconductors, researchers from Science Tokyo report. Their approach relies on ...
Phys.org / Volcanic shifts suggest Andes mountain growth comes in powerful bursts rather than a slow and steady rise
Scientists have discovered that the southern Andes Mountains don't rise slowly and steadily as previously thought. Instead, the range builds itself in short, powerful "pulses" every few million years.
Phys.org / Swiss lake symbiosis reveals unexpected role in nitrogen cycling
A publication led by researchers from the Max Planck Institute for Marine Microbiology in Bremen, Germany, shows that microscopic partnerships between ciliates and bacteria play a role in the nitrogen cycle of lakes. The ...
Phys.org / New swine influenza vaccination technique can greatly strengthen disease protection
Husker scientists have developed a new swine influenza vaccination technique whose low cost and adaptability can greatly strengthen disease protection.
Phys.org / Tracing a neutrino ghost to a distant 'shadow blaster' galaxy
Neutrinos are one of the fundamental particles of the universe. They live a ghostly existence with no electric charge, very little mass and extremely few interactions with matter. They are also the most abundant particles ...
