Hydrogen-producing enzyme protects itself against oxygen
An international research team from the Photobiotechnology Research Group at Ruhr-Universität Bochum (RUB) led by Professor Thomas Happe and the Laboratoire de Bioénergétique et Ingénierie des Protéines (CNRS) in Marseille has been able to get t.....»»
Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
To "breathe" in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons (produced during the "burning" of nutrients) to electric hairs called nanowires projecting fro.....»»
Hypoxia is widespread and increasing in the ocean off the Pacific Northwest coast, study shows
Low oxygen conditions that pose a significant threat to marine life are widespread and increasing in coastal Pacific Northwest ocean waters as the climate warms, a new study shows......»»
Scientists find one of the most ancient stars that formed in another galaxy
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your ve.....»»
Regulating atomic Fe-Rh site distance for efficient oxygen reduction reaction
In a study published in the journal Science China Chemistry, the authors systematically design and investigate the site-distance effect of Fe-Rh atom catalysts (Fe-Rhx@NC) supported by N-doped graphene for ORR by an integrated theoretical and experim.....»»
The Honda CR-V e:FCEV is a plug-in fuel-cell hybrid nobody asked for
Hydrogen has problems, and this isn't a solution, but it's a decent CR-V. Enlarge / We still think hydrogen fuel cells make more sense for static generators like the ones in the background, but Honda decided to make a fuel cell-p.....»»
Report: Sony stops producing PSVR2 amid “surplus” of unsold units
Pricy tethered headset falters after the modest success of original PSVR. Enlarge / PSVR2 (left) next to the original PSVR. (credit: Kyle Orland / Ars Technica) It looks like Sony's PlayStation VR2 is not living up to th.....»»
BMW apologizes after criticism from annual Chinese consumer show
BMW 530Li transmission shaft was singled out on the country's annual consumer day gala television show for producing "disturbing" noises......»»
Energy Department spending $750 million to boost hydrogen, and GM will share
The 52 hydrogen projects are designed to accelerate adoption of clean hydrogen as a viable energy source. General Motors and Bosch are among the companies receiving funding......»»
New catalyst accelerates release of hydrogen from ammonia
Germany can probably only meet its demand for climate-friendly hydrogen by imports, for example, from South America or Australia. For such long-distance transport, hydrogen can be converted into ammonia......»»
Researchers use genetic engineering to create flood-tolerant plants
Adding too much water to your plants can damage them as much as not having enough water. In the environment, plants submerged under excessive rain have limited access to light and oxygen, which reduces or eliminates their ability to thrive. This pose.....»»
A new approach to producing high-performance plastics from agricultural waste
In our rapidly industrialized world, the quest for sustainable materials has never been more urgent. Plastics, ubiquitous in daily life, pose significant environmental challenges, primarily due to their fossil fuel origins and problematic disposal......»»
Jailbreaking an iPhone re-enables blood oxygen measurement on Apple Watch; August 2028 expiry
An interesting look behind the scenes of the court battle between Apple and health tech company Masimo reveals that jailbreaking an iPhone re-enables blood oxygen measurement on an Apple Watch. The same report notes that even if Apple doesn’t su.....»»
Jupiter"s moon Europa produces less oxygen than we thought—it may affect our chances of finding life there
Jupiter's icy moon Europa has long been thought of as one of the most habitable worlds in the Solar System. Now the Juno mission to Jupiter has directly sampled its atmosphere in detail for the first time. The results, published in Nature Astronomy,.....»»
Quantum imaging could create bright future for advanced microscopes
The unique properties of quantum physics could help solve a longstanding problem that prevents microscopes from producing sharper images at the smallest scales, researchers say......»»
Producing more but understanding less: The risks of AI for scientific research
A psychologist and an anthropologist ponder the epistemic risks AI could pose for science. Enlarge / Current concerns about AI tend to focus on its obvious errors. But psychologist Molly Crockett and anthropologist Lisa Messeri a.....»»
A consortium of algae and bacteria boosts the production of green hydrogen and biomass while cleaning water
The mutual relationship between algae and three bacteria studied by a team at the University of Cordoba presents the highest hydrogen production obtained so far by this type of consortium.....»»
How does a river breathe? The answer could lead to a better understanding of the global carbon cycle
Take a deep breath. Pay attention to how air moves from your nose to your throat before filling your lungs with oxygen. As you exhale your breath, a mix of oxygen and carbon dioxide leaves your nose and mouth......»»
How did evolution produce a firefly?
A new study looks at the development of a firefly's light-emitting organs. Enlarge (credit: Xinhua Fu) On one level, we have fireflies figured out. We know the enzyme they use to make light (called luciferase), as well a.....»»
The role of PbrChiA chitinase in ROS regulation and antifungal activity
Pear ring rot, a significant threat to pear production, is caused by Botryosphaeria dothidea, leveraging the complex dynamics of reactive oxygen species (ROS) during infection. Initially, plants employ their innate immune system, detecting pathogens.....»»
Jupiter’s icy moon Europa may be light on oxygen, lowering habitability hopes
New research pours cold water on the likelihood of Europa being habitable, as it seems that the moon produces less oxygen than previously thought......»»
