‘Feel good’ brain messenger can be willfully controlled, new study reveals: Neuroscientists show that mice can learn to manipulate random dopamine impulses for reward

|

From the thrill of hearing an ice cream truck approaching to the spikes of pleasure while sipping a fine wine, the neurological messenger known as dopamine has been popularly described as the brain’s “feel good” chemical related to reward and … Read More

Potential role of ‘junk DNA’ sequence in aging, cancer

|

The human body is essentially made up of trillions of living cells. It ages as its cells age, which happens when those cells eventually stop replicating and dividing. Scientists have long known that genes influence how cells age and how … Read More

Anatomy of the red planet: Mars-quakes reveal interior

|

Researchers have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. Source link

Eyes wide shut: How newborn mammals dream the world they’re entering

|

As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight? A new Yale study suggests that, in a … Read More

Clever cockatoos learn through social interaction, study finds: Research confirms that ‘cockies’ learn unique bin-opening behavior by copying others

|

For the first time, a team of international scientists have proven that cockatoos, an iconic Australian bird species, learn from each other a unique skill — lifting garbage bin lids to gather food. The world-first research published today in Science, … Read More

Scientists reverse age-related memory loss in mice

|

Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age. In a study published today in Molecular … Read More

15,000-year-old viruses discovered in Tibetan glacier ice: Most of the viruses were previously unknown to humans, study finds

|

Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have … Read More

Making clean hydrogen is hard, but researchers just solved a major hurdle

|

For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source — splitting water molecules to form hydrogen and oxygen. However, such efforts have … Read More

Millimeter-tall ‘mountains’ on neutron stars

|

New models of neutron stars show that their tallest mountains may be only fractions of millimetres high, due to the huge gravity on the ultra-dense objects. The research is presented today at the National Astronomy Meeting 2021. Neutron stars are … Read More

Climate change to bring more intense storms across Europe

|

Climate change is driving a large increase in intense, slow-moving storms, a new study by Newcastle University and the Met Office has found. Investigating how climate affects intense rainstorms across Europe, climate experts have shown there will be a significant … Read More

‘Neuroprosthesis’ restores words to man with paralysis: Technology could lead to more natural communication for people who have suffered speech loss

|

Researchers at UC San Francisco have successfully developed a “speech neuroprosthesis” that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on … Read More

Rats prefer to help their own kind; Humans may be similarly wired

|

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new research from the University of California, Berkeley, pinpoints the brain regions that drive rats to prioritize … Read More

Physicists take big step in race to quantum computing: Team develops simulator with 256 qubits, largest of its kind ever created

|

A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or “qubits.” The system marks … Read More

Our genes shape our gut bacteria, new research shows

|

Our gut microbiome — the ever-changing “rainforest” of bacteria living in our intestines — is primarily affected by our lifestyle, including what we eat or the medications we take, most studies show. But a University of Notre Dame study has … Read More

A peek inside a flying bat’s brain uncovers clues to mammalian navigation

|

When driving up to a busy intersection, you probably pay more attention to where you will be in the near future than where you are at that moment. After all, knowing when you will arrive at the intersection — and … Read More

Team find brain mechanism that automatically links objects in our minds

|

When people see a toothbrush, a car, a tree — any individual object — their brain automatically associates it with other things it naturally occurs with, allowing humans to build context for their surroundings and set expectations for the world. … Read More
