Origin of cultural learning: Babies imitate because they are imitated
A new study shows that babies learn to imitate others because they themselves are imitated by caregivers.
Atlantic walrus more vulnerable than ever to Arctic warming
Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.
Tiny CRISPR tool could help shred viruses
Scientists mapped out the three-dimensional structure of one of the smallest known CRISPR-Cas13 systems then used that knowledge to modify its structure and improve its accuracy.
Saturated fat may interfere with creating memories in aged brain
New research hints at a few ways fatty foods affect cells in the brain, a finding that could help explain the link between a high-fat diet and impaired memory — especially as we age. A new study in cell cultures found the omega-3 fatty acid DHA may he…
Strength is in this glass’s DNA
Scientists were able to fabricate a pure form of glass and coat specialized pieces of DNA with it to create a material that was not only stronger than steel, but incredibly lightweight.
How the heart starts beating
Researchers discover that heart cells in developing zebrafish start beating suddenly and all at once
Important additional driver of insect decline identified: Weather explains the decline and rise of insect biomass over 34 years
Combinations of unfavorable weather conditions over several years can cause a decline in insect biomass.
Down goes antimatter! Gravity’s effect on matter’s elusive twin is revealed
For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules ou…
How to save plants from climate change? Just ask them
Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for …
A close-up of biological nanomachines: Researchers take a deep look at peroxisomal processes
The cell organelles known as ‘peroxisomes’ dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. The ‘Pex’ group of proteins (peroxisomes biogenesis factors) keep these ‘detox units’ …
