If zebra finches are prevented from singing for two weeks, they sing at a lower pitch - but they soon recover once they resume daily practice

Improved cognition was seen in older adults who learned multiple new tasks, and the improvements got better as time passed, a new study reports.

Stars emit light that travels through empty space without significant attenuation. The visual signal is essentially lossless until detected. After many years and billions of kilometers, starlight-photons may eventually e...

The element samarium has been spotted in the atmosphere of a planet called MASCARA-4b, breaking the record for heaviest element ever detected in a world beyond our solar system

A new imaging probe revealed an increase in iron redox in brain areas where amyloid plaques occur in the brain in Alzheimer's disease.

A stronger sense of purpose enhances cognitive resilience in middle-aged adults, a new study reports. Those who report greater purpose in life have greater functional connectivity between the default mode network and oth...

In the future, communications networks and computers will use information stored in objects governed by the microscopic laws of quantum mechanics. This capability can potentially underpin communication with greatly enhan...

Using data from the game "Ebb and Flow", researchers are training machine learning algorithms to mimic the human ability to switch attention between tasks. The findings shed new light on cognitive control and may expand ...

Researchers created a high-definition scan of a mouse's brain that is 64 million times sharper than a normal MRI.

Researchers identified a subset of neurons in the mammillary body of the hypothalamus which are susceptible to hyperactivity and neurodegeneration. This damage often leads to memory impairment associated with Alzheimer's...

In the formation of the cerebellum, the outer layer cells in a baby's brain communicate with each other in a unique way using nanotubes. This happens before the synapses are formed.

Some carnivorous plants seem to tailor the cocktail of scents they emit to the prey they want to attract, which shows that their smell plays a key role in luring insects and other creatures

A parasitic microorganism with tiny hair-like structures over its body called a ciliate appears to be behind the mass die-off of long-spined sea urchins across the Caribbean

The 2022 Nobel Prize in Physics was awarded to Alain Aspect, John Clauser, and Anton Zeilinger for their works on "quantum nonlocality" in quantum mechanics. Quantum nonlocality is a phenomenon where connected particles ...

The orbital angular momentum (OAM) of electromagnetic waves--a kind of "structured light"--is associated with a helical or twisted wavefront.

Global temperatures did not plummet in the aftermath of the asteroid impact that caused the demise of the dinosaurs, a new study suggests.

While more altruistic people can be distinguished from typical adults by their unselfish traits and actions, they are generally not different in other ways. Altruistic people are no more agreeable or conscientious than o...

Topological acoustics provides a new approach for manipulating acoustic waves using the novel wave transport phenomenon. In less than a decade, it has provided a series of promising new ideas for the directional control ...

Stimulating glutamatergic neurons in the cuneiform nucleus may improve walking recovery in those with spinal cord injury.

Brain areas that control movement are plugged into networks that orchestrate thinking and planning, and control involuntary bodily functions. The findings provide a link between the body and the "mind" in the brain's str...

Marine algae could replace plastic, massively cut our carbon emissions and help feed billions of people healthily, according to an excellent new book by Vincent Doumeizel

Existential risk from AI is admittedly more speculative than pressing concerns such as its bias, but the basic solution is the same. A robust public discussion is long overdue, says David Krueger
