Medical Xpress / Excessive cholesterol in astrocytes linked to cognitive decline in Alzheimer's mice
Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of the protein amyloid-β ...
Tech Xplore / Water-based zinc batteries tackle a barrier that has long blocked cheap, stable renewable energy storage
Renewable energy technologies, such as solar cells and wind turbines, are becoming increasingly widespread in many countries worldwide. Reliably storing the electricity produced by these devices, so that it can be used later ...
Phys.org / Bacterial defense system builds DNA in unexpected new way to stop viruses
Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called reverse transcriptases, ...
Phys.org / How rocks trap CO₂ faster: Water-driven pathway could speed long-term carbon storage
Rocks can bind carbon dioxide—and much faster than previously thought. For a long time, it was assumed that the transformation of CO2 into carbonate rock depends on very slow, time-consuming processes. According to that view, ...
Phys.org / Two blazing quasars caught waltzing into a merger
Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar pair housed in a pair of merging galaxies seen when the universe was less than a billion years old, ...
Phys.org / How the Ampelomeryx grew: Discovering the life history of a giraffe relative that lived in Catalonia
A research team from the Institut Català de Paleontologia Miquel Crusafont (ICP-CERCA) has led the paleohistological study of Ampelomeryx ginsburgi, a giraffomorph ruminant from the Middle Miocene recovered at the Els Casots ...
Medical Xpress / New autism therapy may improve children's social communication in just five days
A new non-invasive brain stimulation technique known as accelerated continuous theta burst stimulation (a-cTBS) improves social communication at one month follow-up and has a favorable safety profile in children with autism, ...
Phys.org / Tiny flexible lasers enable force sensing inside living cells
Researchers have developed tiny flexible lasers that can be used to measure forces inside living cells. The new lasers could help illuminate various biological processes, including those involved in early development and ...
Phys.org / Near-relativistic swarm could image Proxima b at 20-meter resolution and scan for biosignatures, paper says
Laser sail propulsion is an idea that won't go away. By aiming powerful Earth-based lasers at tiny spacecraft with light sails, tiny spacecraft can be accelerated to near-relativistic speeds without carrying fuel or an energy ...
Phys.org / Beer waste may become sunscreen ingredient after spent hops show promising UV protection
Research conducted at the University of São Paulo (USP) in Brazil revealed that hops (Humulus lupulus L.) industrial waste from the brewing industry is a viable option for sunscreen formulation production. The multidisciplinary ...
Phys.org / AI classifier flags bird flu genomes more likely to spread in mammals
A research team from the LKS Faculty of Medicine at the University of Hong Kong (HKUMed) has developed a machine-learning classifier capable of analyzing the genomes of influenza A viruses (IAVs) to accurately predict their ...
Tech Xplore / Evolving AI may arrive before AGI and create hard-to-control risks
Evolutionary biology holds clues for the future of AI, argue researchers from the HUN-REN Centre for Ecological Research, Eötvös Loránd University, and the Royal Flemish Academy of Belgium for Science and the Arts. In a new ...
