Aggressive wall lizard provides clues to understanding evolution
Body shape, color and behavior often evolve together as species adapt to their environment. Researchers from Lund University in Sweden have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near.....»»
Bacteria "nanowires" could help develop green electronics
Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity. In a study published recently in the journal Small, researchers revealed that protein nanowires—which were modified by adding a si.....»»
The Mysterious ‘Dark’ Energy That Permeates the Universe Is Slowly Eroding
Physicists call the dark energy that drives the universe “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years......»»

NIMS has succeeded in simulating the magnetization reversal of Nd-Fe-B magnets using large-scale finite element models constructed based on tomographic data obtained by electron microscopy......»»
Recovering phosphorus from sewage sludge ash to address problem of diminishing supplies of phosphorus ores
Valuable supplies of phosphorus could be recovered from sewage sludge ash, which remains after the sludge has been burned for electric power generation. The method has been developed by chemical engineers Yuuki Mochizuki and Naoto Tsubouchi at Hokkai.....»»
Scientists regenerate neural pathways in mice with cells from rats
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present n.....»»
Synthesis of two new carbides provides perspective on how complex carbon structures could exist on other planets
Researchers at the University of Bayreuth have gained new insights in the field of high-pressure carbon chemistry: They synthesized two new carbides—compounds of carbon and another chemical element—with unique structures. The results may provide.....»»
Scholars explain the ideology that says technology is the answer to every problem
Silicon Valley venture capitalist Marc Andreessen penned a 5,000-word manifesto in 2023 that gave a full-throated call for unrestricted technological progress to boost markets, broaden energy production, improve education and strengthen liberal democ.....»»
Warming Arctic reduces dust levels in parts of the planet, study finds
Climate change is a global phenomenon, but its impacts are felt at a very local level. Take, for example, dust. Dust can have a huge impact on local air quality, food security, energy supply and public health. Yet, little is known about how global cl.....»»
We may have spotted the first magnetar flare outside our galaxy
Not all gamma-ray bursts come from supernovae. Enlarge / M82, the site of what's likely to be a giant flare from a magnetar. (credit: NASA, ESA and the Hubble Heritage Team) Gamma rays are a broad category of high-energy.....»»
U.S. EV battery upstart, Hyundai-Kia close in on lithium metal battery commercialization
SES AI, a U.S. maker of electric vehicle batteries, aims to bring its next-gen lithium metal batteries to market as early as 2026 and is turbocharging the drive through a new agreement to jointly build and test the technology with South Korea's Hyund.....»»
Africa"s megacities threatened by heat, floods, disease—action needed to start greening, adapt to climate change
Cities cover just 3% of the planet. But they emit 78% of all global greenhouse gas emissions, absorb 80% of final global energy (what consumers use) and consume 60% of clean drinking water......»»
International team detects eruption of mega-magnetic star in nearby galaxy
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explos.....»»
