A study takes a closer look at the neurobiology of psychedelic experiences caused by nitrous oxide, ketamine and LSD.

A new trial has found a new genetic therapy for Alzheimer’s disease that is able to safely and successfully lower levels of the harmful tau protein known to cause the disease.

It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers have now succeeded in uniting all of these characteristics in zinc metal batteries.

Pet rabbits have higher levels of the stress hormone — corticosterone — and show activity rebound when kept in small hutches with restricted exercise, new research has found.

Viruses like influenza A and Ebola invade human cells in a number of steps. Research teams investigated the final stages of viral penetration using electron tomography and computer simulations. So-called fusion pores, through which the viral genome is …

Supply chain networks can be incredibly complex, with multiple manufacturing and distribution points — and the location of each node in those networks has a significant effect on everything from profitability to product cost to environmental impact. N…

We have known for a while that asteroid 3200 Phaethon acts like a comet. It brightens and forms a tail when it’s near the Sun, and it is the source of the annual Geminid meteor shower, even though comets are responsible for most meteor showers. Scienti…

Finger fracture, traumatic brain injury, and shoulder sprain or strain were the three most common injuries related to leash-dependent dog walking among adults treated in U.S. emergency rooms from 2001 to 2020. Researchers have found that traumatic brai…

Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radia…

Scientists carried out an analysis of hundreds of popular song recordings from 1946 to 2020 to determine the lead vocal to accompaniment ratio, or LAR. The study considered the four highest-ranked songs from the Billboard Hot 100 chart for each year an…

Researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibe…

Researchers model the behavior of blood drops during secondary atomization to examine how the phenomenon affects a crime scene. The team examined different starting droplet sizes, confirming their model with experiments. They found the effect of second…

Researchers develop a model to describe the interaction between a rocket plume and the surface of a planetary body in near-vacuum conditions. The computational framework takes in information about the rocket, its engines, and the surface composition an…

A new study has highlighted under-prepared regions across the world most at risk of the devastating effects of scorching temperatures.

Helping your mother make pancakes when you were three…riding your bike without training wheels…your first romantic kiss: How do we retain vivid memories of long-ago events?

New research shows that poor air quality could be causing cognitive problems in babies and toddlers. A new study reveals an association between poor air quality in India and impaired cognition in infants under two. Without action, the negative impact o…

Genetic analysis links 3,000-year-old bone found in cave to modern Alaska Natives.

Blinking is crucial for the eye. It’s how animals clean their eyes, protect them, and even communicate. But how and why did blinking originate? Researchers have studied the mudskipper, an amphibious fish that spends most of its day on land, to better u…
