Phys.org / Adrift like Shackleton: Robot float survives Antarctic ice
A robotic float has measured the temperature and salinity from parts of the ocean never sampled before—underneath massive floating ice shelves in East Antarctica.
Phys.org / Reconfigurable platform slows lights for on-chip photonic engineering
Integrated circuits are the brains behind modern electronic devices like computers or smart phones. Traditionally, these circuits—also known as chips—rely on electricity to process data. In recent years, scientists have ...
Phys.org / Webb reveals double helium tails escaping from a 'hot Jupiter'
For the first time, scientists have continuously monitored a planet's escaping atmosphere over a complete orbit, revealing that the gas giant WASP-121 b is surrounded by not one but two massive helium tails stretching more ...
Phys.org / Parasitic fungus may have emerged 18 million years before the ants with which it lives today
A genus of fungi previously considered a parasite of fungi associated with ants may actually have much more complex ecological functions. According to a study published in the journal Communications Biology, one piece of ...
Phys.org / Plant-virus proteins guide gold nanoparticles into eco-friendly sheets for solar tech
Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles' optical properties. ...
Phys.org / NASA-JAXA XRISM finds elemental bounty in supernova remnant
For the first time, scientists have made a clear X-ray detection of chlorine and potassium in the wreckage of a star using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft.
Phys.org / New model describes how reaction-diffusion networks develop 'foams'
For numerous fundamental processes of life, the formation of certain protein patterns is essential. Protein pattern formation controlled by molecular switches is—like many processes in nature—far removed from a state ...
Phys.org / Towards sustainable organic synthesis—mechanochemistry replaces lithium with sodium in organic reactions
Highly reactive organometallic reagents, like organolithiums (molecules with a carbon–lithium bond) are essential reagents in organic synthesis because of their applications from polymer synthesis to pharmaceuticals, and ...
Phys.org / Hydrogel switches from liquid to gel at body temperature, enabling easy removal
What if a doctor could inject an electricity-conducting liquid into the body, let it temporarily solidify to record nerve signals or jump-start healing, and then return it to liquid form for easy removal?
Phys.org / Global shift to sustainable pest management expected to yield long-term benefits
What would happen if farmers around the globe were to switch over to sustainable pest management? An international study headed by the University of Bonn and ETH Zurich focused on precisely this question. The study is based ...
Phys.org / Estimating the number of flying insects in the US using weather radar
Although millions upon millions of living creatures fly, feed and reproduce in the air, this habitat has hardly been researched. Insects are under increasing pressure worldwide due to global change and human activities. However, ...
Phys.org / Bacterium's molecular speargun defense may leave it exposed to antibiotics
Countless bacterial species share cramped environments where competition for space and resources is fierce. Some rely on a molecular speargun to outcompete their opponents. One of them is Pseudomonas aeruginosa. It is widespread ...
