James Webb telescope reveals that asteroids Bennu and Ryugu may be parts of the same gigantic space rock
Live Science - 21 Aug 2025 21:28
New data from the James Webb telescope suggests that Bennu and Ryugu - two asteroids recently visited by sample-return missions - are both fragments of a single massive "parent".
How Stress Types Differently Impact Brain and Behavior
Neuroscience News - 21 Aug 2025 20:59
Stress is a universal experience, but not all stress affects the brain in the same way. A new study in rats reveals that acute stress provokes anxiety-like behaviors, especially in males, while chronic stress is more str...
We could get most metals for clean energy without opening new mines
New Scientist - 21 Aug 2025 20:00
An analysis of active US mines finds they already collect virtually all of the minerals the country needs for batteries, solar panels and wind turbines - but these critical minerals mostly go to waste
The colour of your car has a big impact on urban heat
New Scientist - 21 Aug 2025 20:00
Dark-coloured cars can make a measurable difference on nearby air temperature, and in cities of millions the effect can add up and noticeably increase how hot it feels
The first Americans had Denisovan DNA. And it may have helped them survive.
Live Science - 21 Aug 2025 19:25
People with Indigenous American ancestry carry Denisovan genes that Neanderthals passed on when they mated with modern humans.
Nighttime Brain Activity Keeps Glucose Levels in Check
Neuroscience News - 21 Aug 2025 19:17
A new study reveals that the brain actively maintains blood sugar stability during everyday life, not just during crises. Researchers identified VMHCckbr neurons in the hypothalamus that regulate glucose by promoting fat...
How to tackle environmental issues when the world can't agree
New Scientist - 21 Aug 2025 18:26
The failure to agree a global treaty on plastic pollution highlights how the UNs requirement for unanimity holds back environmental policy, but there are better ways to make progress
Education Gap Is Speeding Up Aging in Millions of People
Neuroscience News - 21 Aug 2025 18:05
A new study reveals that Americans with less education are aging faster than those with more schooling, and the divide has widened over the past three decades. Biological age-measuring internal health rather than years l...
Brain Retains Lost Limbs Control Map, Defying Plasticity Theories
Neuroscience News - 21 Aug 2025 17:16
A groundbreaking study challenges decades of neuroscience by showing that the brain retains its map of a lost limb long after amputation. Using functional MRI scans taken before and after surgery, researchers found littl...
An 'equinox solar eclipse' is coming in September - but it'll be seen by more penguins than humans
Live Science - 21 Aug 2025 17:11
A partial solar eclipse is taking place just hours before the equinox flips Earth's seasons in September 2025. Here's where a few lucky humans will be able to see it.
Long-Term Nicotine Use Delays Aging-Linked Motor Decline
Neuroscience News - 21 Aug 2025 17:01
A new study demonstrates that long-term oral nicotine administration reprograms aging-related metabolism and slows motor decline in mice. By targeting the sphingolipid-energy axis, nicotine improved energy homeostasis, p...
Gene Blueprint of Neural Stem Cells in the Brain Identified
Neuroscience News - 21 Aug 2025 16:46
A new study has mapped the genetic blueprint of neural stem and progenitor cells (NPCs), the rare cells responsible for generating new neurons in the adult brain. Using a digital sorting algorithm and cross-species analy...
Hidden symmetries unlock new ways to control light in quantum materials
Phys.org - 21 Aug 2025 16:31
A team of researchers has discovered how a little-known type of symmetry in quantum materials, called nonsymmorphic symmetry, governs the way these materials interact with intense laser light.
Symmetry-based Floquet optical selection rules help explain light-induced sidebands
Phys.org - 21 Aug 2025 16:12
