When I was a young kid, our neighborhood didn't have any grocery stores. The only place to buy fruits and vegetables was at our local farmer's market. My mom would pick out the freshest tomatoes and sauté them with eggs...

Metamaterials are artificial materials that do not occur in nature. Their components function like atoms in conventional materials but have special optical, electrical and magnetic properties. Interaction between the com...

Research suggests that certain antiseizure medications taken during pregnancy may increase the risk of neurodevelopmental conditions in children. Drugs like valproate, topiramate, and carbamazepine were associated with s...

New research has revealed the diverse assembly and regulation of Type-A GABA receptors (GABAARs), which are crucial for balancing brain activity. Using cryogenic electron microscopy, researchers identified over 324,000 p...

Attempts to prevent Australian children from accessing social media are likely to fail, and could do more harm than good

New research uncovers how mitophagy, the cellular recycling of damaged mitochondria, changes dynamically in the aging mammalian brain. In memory-related cells, mitophagy rises in midlife but declines sharply in old age, ...

The Lafayette meteorite was discovered in a drawer at Purdue University in 1931, with no clear indication of how it got there. A new analysis of the rock reveals evidence of liquid water on Mars 742 million years ago.

Researchers have developed the Mouse Aging Proteomic Atlas, a comprehensive database detailing protein changes in major tissues as mice age. By analyzing proteomes and transcriptomes across tissues like the brain, heart,...

In a recent study, researchers have developed a compound metalens that enables distortion-free imaging. The study, published in Engineering, presents a novel approach to on-demand distortion engineering using compound me...

Modern imaging systems, such as those used in smartphones, virtual reality (VR), and augmented reality (AR) devices, are constantly evolving to become more compact, efficient, and high-performing. Traditional optical sys...

Researchers have discovered how stress disrupts memory specificity, leading to generalized aversive memories--a hallmark of PTSD. Stress increases endocannabinoid release, enlarging memory engrams in the brain, which tri...

Immune cells produced during severe COVID-19 infection may shrink tumors. The unexpected mechanism offers a new therapeutic possibility for advanced and treatment-resistant cancers.

Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists at the Max Planck Institute for the Science of Light (MPL) have de...

Researchers at Universit Cattolica, Brescia campus, have discovered that the transition from insulating to conductive behavior in certain materials is driven by topological defects in the structure.

The budget-friendly ProForm 750R rowing machine is even better value than ever with this price cut.

Researchers have analyzed mummified remains pulled from Siberia's permafrost in 2020 and determined they belong to a 3-week-old saber-toothed kitten that died at least 35,000 years ago.

Until now, Antarctica was the only continent on Earth without any known amber fossils. But sediment cores taken from below the seafloor have revealed a tiny piece of fossilized resin holding fragments of an ancient rainf...

Explore the skies for less with the Celestron SkyMaster Pro 20x80 at their lowest price since February -- now $210 ahead of Black Friday

The sacrifice of at least 42 children in Tenochtitlán, now Mexico City, was an effort to calm the anger of the Aztec rain god during a devastating drought, researchers have revealed.

The world's biggest coral -- an organism made up of about a billion polyps -- is about three times bigger than the previous record-holder and was discovered by chance during an expedition off the Solomon Islands.

Letting AI models communicate with each other in their internal mathematical language, rather than translating back and forth to English, could accelerate their task-solving abilities

After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, scientists decided to experiment in real life -- and found that laser beams can indeed cast a s...
