A poison helps us understand molecular hydrogen-producing biocatalysts
In nature, enzymes termed hydrogenases are capable of producing molecular hydrogen (H2). Special types of these biocatalysts, so-called [FeFe]-hydrogenases, are extremely efficient and therefore of interest for biobased hydrogen production. Although.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Bulrush once kept NZ"s wetlands and lakes thriving—now it could help restore them
With about 90% of New Zealand's natural wetlands drained or severely damaged during the past decades, we need to understand the role of native plants in the restoration of these important habitats......»»
Scientists uncover a critical component that helps killifish regenerate their fins
Spontaneous injuries like the loss of a limb or damage to the spinal cord are impossible for humans to repair. Yet, some animals have an extraordinary capacity to regenerate after injury, a response that requires a precise sequence of cellular events.....»»
How social structure influences the way people share money
People around the globe often depend on informal financial arrangements, borrowing and lending money through social networks. Understanding this sheds light on local economies and helps fight poverty......»»
‘That’s weird’: This galaxy could help astronomers understand the earliest stars

Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
Reproductive coercion is a form of gender-based violence—it"s likely more common than most understand
From contraception access to safe abortion, there is growing awareness about reproductive health and rights......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
GM, Piston plot hydrogen fuel cell factory in Detroit
GM and Piston Automotive are plotting a hydrogen fuel cell factory in Detroit, GM's first standalone plant for fuel cell production......»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
Researchers refute the validity of "assembly theory of everything" hypothesis
Three new papers refute claims for the assembly theory of molecular complexity being claimed as a new "theory of everything.".....»»
Low-temperature ammonia-to-hydrogen conversion achieved by applying an electric field
Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound sta.....»»
The "publish or perish" mentality is fueling research paper retractions—and undermining science
When scientists make important discoveries, both big and small, they typically publish their findings in scientific journals for others to read. This sharing of knowledge helps to advance science: it can, in turn, lead to more important discoveries......»»

Cloudflare announced a new service to verify the integrity of public keys in the end-to-end encryption of popular messaging applications. When using end-to-end encryption messaging applications, a public-private key exchange encrypts messages to prot.....»»
How cyber compliance helps minimize the risk of ransomware infections
Over the past decade, ransomware has been cemented as one of the top cybersecurity threats. In 2023 alone, the FBI received 2,385 ransomware complaints, resulting in over $34 million in losses. To help businesses combat ransomware and other threats,.....»»
Potential indicators of life on other planets can be created in a lab
One way to understand the potential for life on far-off planets—those in other solar systems that orbit different stars—is to study a planet's atmosphere. Telescopic images often capture traces of gases that may indicate life and habitable planet.....»»
