It's a dangerous combo.

White-throated sparrows normally end their song with repeated triplets, but a new song ending in repeated double notes has been sweeping a population in Canada

Windows filled with water rather than argon gas could save energy in most of the world, partly because they can provide a cheap source of hot water

The vitality of preterm infants should be assessed with an Apgar score, a tool used to measure the health of newborns immediately after birth. That is the conclusion by researchers who in a large observational study exam...

Infecting volunteers with COVID-19 may provide valuable insights for future rounds of vaccine testing, but would require very strict controls and is unlikely to advance the current slate of vaccines in advanced developme...

As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it to quell morning sickness. But new research suggests such use could have a lasting impact on the fetal brain, influe...

Getting married early in life may increase the risk of problematic drinking behavior among people who are genetically predisposed to drink more.

New technologies capable of sequencing single molecules in fine detail will help scientists better understand the mechanisms of rare nucleotides thought to play an important role in the progression of some diseases.

New research has found that women who have hot flushes and night sweats after menopause are 70 per cent more likely to have heart attacks, angina and strokes.

Researchers have developed a new method to convert gaseous, low-weight hydrocarbons into more complex molecules by illuminating the hydrocarbons with light in the presence of a suitable catalyst.

Repeated measurements of the biomarker FIB-4 in the blood every few years can predict the risk of developing severe liver disease, according to a new study. The risk of liver cirrhosis increases if the levels of this bio...

In a study done with mice, researchers found that a diet high in black raspberries reduced inflammation from contact hypersensitivity -- a condition that causes redness and inflammation in the skin.

A new study provides evidence supporting a link between 'COVID toes' -- red sores or lesions on the feet and hands in children and young adults -- and COVID-19.

Health care providers may unintentionally expose patients to endocrine- disrupting chemicals (EDCs) by prescribing certain medications and using medical supplies, according to a new perspective.

New research shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture.

Artificial enzymes made of treated charcoal could have the power to curtail damaging levels of superoxides, toxic radical oxygen ions that appear at high concentrations after an injury.

Scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means. These findings help explain how organisms' circadian clocks maintain flexibility and could offer ins...

In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of preda...

Researchers have developed a safer and more efficient way to deliver a promising new method for treating cancer and liver disorders and for vaccination.

Nitrous oxide may provide temporary relief to veterans suffering from PTSD, a new study reports.
