Phys.org / Stale bread and bacteria could power a new era in green chemicals
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products ...
Phys.org / Scientists synthesize stable N₄ radical anions under ambient conditions
A team of scientists from the University of Manchester and Oxford have synthesized stable nitrogen chain radical anions under ambient conditions. These molecules, which are normally too reactive to isolate and study under ...
Phys.org / Missing methane: Countries may be underestimating wastewater greenhouse gas emissions
The amount of greenhouse gases produced by the wastewater sector may be higher than reports suggest. According to a paper published in the journal Nature Climate Change, countries are missing out on reporting a significant ...
Phys.org / PFAS exposure greater in wet pet food, study suggests
Ehime University investigators measured 34 per- and polyfluoroalkyl substances in 100 commercial dog and cat foods sold in Japan and detected PFAS across many products, with higher concentrations in fish-based foods and dry ...
Phys.org / Bioengineered neuronal 'circuit board' mimics conditions of the human brain
A new bioengineered neuronal circuit board "BioConNet" allows scientists to artificially engineer human brain-like wiring at scale and can be used to engineer any possible circuit. The fully programmable, open-source system ...
Phys.org / Svalbard polar bears gained fat despite rapid Barents Sea ice loss
Their icy hunting grounds are rapidly shrinking, but polar bears in Norway's remote Svalbard archipelago have defied the odds by bulking up instead of wasting away, a study said Thursday.
Phys.org / Saturday Citations: T. Rex on tiptoe; subduing unruly proteins; opinionated birds
This week, astronomers reported that one of the biggest observed stars in the universe could soon explode. A study compared long-term COVID-19 brain effects to the flu. And a new eco-friendly battery could theoretically last ...
Phys.org / Metasurface-based SLM could enhance AR, VR and LiDAR performance
Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include ...
Phys.org / Greenland's largest glacier could soon reach a tipping point, scientists say
Greenland's largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published ...
Phys.org / Rising carbon dioxide levels now detected in human blood
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially ...
Phys.org / A new scientific discipline to ensure humanity's deep future
Will humanity extend into the far future? It's likely many of us think it should. The problem is that each of us, individually and collectively, act otherwise—we are destroying the environment and climate at every turn. ...
Phys.org / Could Mars soil block Earth microbes? 'Water bears' offer a clue
Tardigrades, commonly known as water bears, may be better suited by a new name: Tardiguardians of the Galaxy. Unlike the fictional ragtag team of unenthusiastic heroes, the microscopic animals are providing real insight into ...
