Scientists widely accept the existence of quarks, the fundamental particles that make up protons and neutrons. But information about them is still elusive, since their interaction is so strong that their direct detection...

Researchers have developed a compact laser that emits light with extreme spectral purity that doesn't change in response to environmental conditions. The new potentially portable laser could benefit a host of scientific ...

Signaling through interleukin-10 (IL-10) receptors on gut immune cells plays a critical role in protecting the gut lining and microbiota from disruption caused by whipworms, according to a new study.

Known for its role in relieving depression, the neurochemical serotonin may also help the brain execute instantaneous, appropriate behaviors in emergency situations, according to a new study.

Different chemotherapy drugs were associated with varying degrees of long-term risk of cardiomyopathy in survivors of childhood cancers, according to a new study.

A new study has found that a persistent low body mass index (BMI) in children, starting as young as age 2 for boys and 4 for girls, may be a risk factor for the development of anorexia nervosa in adolescence.

A post-exercise snack can threaten to undo the gains (or losses) of a workout. But the decision itself may depend on when you make it, according to a new study. Participants asked to choose between an apple and brownie w...

A strategy inspired by the process responsible for muscle growth could lead to the development of stronger, longer-lasting materials.

Humans spend nearly one-third of their lives in slumber, yet sleep is still one of biology's most enduring mysteries. Little is known about what genetic or molecular forces drive the need to sleep -- until now. In a stud...

A team of researchers has developed a new method to calculate and predict how drug molecules in molecular crystals arrange themselves under changing energetic conditions. For pharmaceutical companies, this approach could...

Obesity -- as research in the past decade has shown -- is first and foremost a brain disease. Researchers have discovered a molecular switch that controls the function of satiety neurons and therefore body weight.

Researchers have discovered a protective mechanism which is used by the body to protect intestinal stem cells from turning cancerous. The body's innate immune system was found to play a pivotal role in this regard. The r...

Research uncovers previously unknown effects of fasting, including notably increased metabolic activity and possible anti-aging effects.

A new study reveals the molecular switch that helps control the function of satiety neurons and body weight.

A new mouse study reveals a small cluster of interneurons in the hippocampus help the brain remember the places that matter the most. The findings could have implications for future studies of psychiatric disorders.

Exercise is associated with improved brain function and a decrease in cerebral blood flow in older people with mild cognitive impairment, a new study reports.

Hacking the Curiosity rover let researchers measure the density of the rocks it was driving over, revealing that Martian mountains may not form how we thought

A self-growing hydrogel becomes stronger and larger with use and could one day help make robots with artificial muscles

More than 80% of parents reported significant or moderate improvements in their child's ASD symptoms following medical cannabis treatment, a new study reports.

Researchers report people with sleep apnea have trouble recalling details of autobiographical memories, putting them at greater risk of developing depression.

A new study reveals taking a short daytime nap can help to consolidate learning and memory of new foreign words.

As mining firms begin tests to pick up metal ores from the Pacific seabed, we need rules to protect this unusual ecosystem, says Olive Heffernan
