During late September and mid-October, the much-anticipated comet C/2023 A3 (Tsuchinshan-ATLAS) could become visible to the naked-eye for skywatchers around the world.

A new study suggests that neurostimulation targeting specific brain circuits may help treat PTSD in veterans. Researchers found that veterans with damage to brain areas connected to the amygdala, the brain's fear center,...

Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley-Queisser efficiency limit, which is a ...

People could previously get the nasal spray flu vaccine, called FluMist, from a health care provider, but now they can administer it themselves.

The psychedelic DOI, a compound similar to LSD, reduced anxiety in mice by activating specific brain cells called fast-spiking interneurons. These neurons silence nearby cells in the ventral hippocampus, a region linked ...

The centuries-old remains at Notre Dame have been identified as Joachim du Bellay, a French Renaissance poet who died at age 37.

Spintronics--devices that use microscopic magnetism in conjunction with electric current--could lead to computing technology as fast as conventional electronics but much more energy efficient. As such devices are develop...

Scientists are conducting experiments in search of evidence of a possible critical point in the Quantum Chromodynamics phase diagram. Quantum chromodynamics describes how the strong force binds quarks and antiquarks toge...

Dopamine was long thought to play a part in the placebo effect for pain relief, but a new study is questioning its true role

When a person (or monkey) is facing stakes that are too high, the stress can interfere with neurons, affecting how they direct the body to execute movements, a study suggests.

Scientists have discovered that neurons in the human brain recognize the number zero as a numerical value, not just "nothing." Using microelectrodes, researchers monitored brain activity in neurosurgical patients and fou...

Philip Seargeant tells us how AI will shape the future of our language use.

Pramipexole, a Parkinson's disease (PD) drug, impairs decision-making by hyperactivating the brain's external globus pallidus (GPe) region. This research uncovers how the medication, while effective for PD symptoms, can ...

In most vertebrates, a pattern of chemical marks on the genome is a reliable indicator of age, but in axolotls this clock seems to stop after the first four years of life

New research is revealing that common sense is a lot more idiosyncratic than we thought, with important implications for tackling political polarisation and the future of AI

The Antarctic ozone hole usually starts forming in early August, but rare warming events and a strangely elongated polar vortex this year may have delayed its arrival.

A new study reveals that infliximab, an anti-inflammatory drug, can improve motivation in patients with depression and high inflammation. Researchers found that patients receiving infliximab showed greater effort in rewa...

The discovery of two entangled quarks at the large Hadron Collider is the highest-energy observation of entanglement ever made.

New research reveals that mixed emotions, like feeling both happy and sad, are processed in distinct areas of the brain. While brain regions tied to rapid emotional responses treat positive and negative feelings as separ...

Certain initial symptoms of multiple sclerosis (MS), like blurry vision and sphincter dysfunction, may predict long-term disability outcomes. Researchers found that patients experiencing these symptoms at disease onset h...

New research reveals that dopamine is not directly responsible for the formation of placebo analgesia, contrary to previous beliefs. In a study with 168 participants, altering dopamine levels did not affect positive trea...

A new study reveals that psilocybin, the active compound in magic mushrooms, may help treat body dysmorphic disorder (BDD) by altering brain connectivity. In a pilot trial, patients with BDD showed significant improvemen...
