Phys.org / Observations catch galaxy cluster in the process of merging
Astronomers have used the Keck Observatory's DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding ...
Phys.org / Humans made fire 350,000 years earlier than believed, archaeological study finds
A team of researchers led by the British Museum has unearthed the oldest known evidence of fire-making, dating back more than 400,000 years, in a field in Suffolk. The discovery shows humans were making fire about 350,000 ...
Phys.org / Converting CO₂ into valuable chemicals in acidic environments: Iodide ions unlock efficient ethylene production
The emission of carbon dioxide (CO₂) is one of the primary factors contributing to air pollution and climate change on Earth. In recent years, energy engineers have thus been trying to develop systems that could reduce ...
Medical Xpress / No, your brain doesn't suddenly 'fully develop' at 25. Here's what the neuroscience actually shows
If you scroll through TikTok or Instagram long enough, you'll inevitably stumble across the line: "Your frontal lobe isn't fully developed yet." It's become neuroscience's go-to explanation for bad decisions, like ordering ...
Phys.org / Study says African penguins starved en masse off South Africa
Endangered penguins living off South Africa's coast have likely starved en masse due to food shortages, a study said, with some populations dropping by 95% in just eight years.
Tech Xplore / All-optical chip achieves 100-fold speed boost over top-tier NVIDIA chips
Scientists in China have unveiled a new AI chip called LightGen that is 100 times faster and 100 times more energy efficient than NVIDIA chips, the leading supplier of AI chips worldwide. Instead of using electricity to move ...
Medical Xpress / Gut bacteria may play role in bipolar depression by directly influencing brain connectivity
Bipolar disorder (BD) is a psychiatric disorder characterized by extreme mood changes. Individuals diagnosed with BD typically alternate between periods of high energy, euphoria, irritability and/or impulsivity (i.e., manic ...
Medical Xpress / A urine-based biological aging clock: Machine learning and microRNA offer accurate prediction
Craif Inc. in Nagoya, Japan, working with Nagoya University's Institute of Innovation for Future Society, has developed a urine-based biological aging clock. In validation of the method, predicted ages came within 4.4 years ...
Phys.org / Kolmogorov-Arnold networks bridge AI and scientific discovery by increasing interpretability
AI has successfully been applied in many areas of science, advancing technologies like weather prediction and protein folding. However, there have been limitations for the world of scientific discovery involving more curiosity-driven ...
Phys.org / Ultracold atoms observed climbing a quantum staircase
For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms.
Phys.org / Cypriot fishermen battle invasive lionfish and turn them into a tavern delicacy
Photis Gaitanos' rough fingers adroitly untangle the venomous spikes of a lionfish from a net, throwing the exotic-looking creature into an ice-filled rubber bin along with other fish from the day's catch.
Medical Xpress / Antiviral trial ties valacyclovir to faster cognitive decline
New York State Psychiatric Institute and Columbia University Medical Center investigators, with co-authors across additional US centers, report greater cognitive worsening at 78 weeks with valacyclovir than with placebo among ...
