Replacing sugar with artificial and natural sweeteners in foods does not make people hungrier — and also helps to reduce blood sugar levels, a significant new study has found. The double blind randomized controlled trial found that consuming food cont…

School quality ratings significantly reflect the preparation of a school’s students, not just the school’s contribution to learning gains, according to new research.

Everyone indulges in wishful thinking now and again. But when is that most likely to happen and when could it actually be harmful? A new study demonstrates unequivocally that the greater the insecurity and anxiety of a situation, the more likely people…

A research consortium provides evidence that social behavior and social status are reflected at the molecular level of gene activation (epigenome) in juvenile and adult free-ranging spotted hyenas. They analyzed non-invasively collected gut epithelium …

Researchers have identified how the tick-borne Crimean-Congo haemorrhagic fever virus enters our cells. The results are an important step in the development of drugs against the deadly disease.

Through DNA sequencing of Tasmanian devils and their tumors, researchers have tracked the genomic interactions between the animals and the cancer.

Scientists have shown that Barkhausen noise can be produced not only through traditional, or classical means, but through quantum mechanical effects. The research represents an advance in fundamental physics and could one day have applications in creat…

A recent study reveals an unexpected link between manganese — a naturally occurring mineral — and increased carbon emissions from high-latitude boreal forests. The study uncovers how manganese increases carbon emissions from boreal forest soil, over …

A single genetic test could potentially replace the current two-step approach to diagnosing rare developmental disorders in children. This shift could enable earlier diagnoses for families and save vital resources.

Neuroscientists have established in recent decades the idea that some of each day’s experiences are converted by the brain into permanent memories during sleep the same night. Now, a new study proposes a mechanism that determines which memories are tag…

A group of international experts has presented a blueprint for national indoor quality standards for public buildings. The experts addressed setting standards for three key indoor pollutants — carbon dioxide, carbon monoxide, and PM2.5 (particles so s…

Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds.

SARS-CoV-2 will eventually become resistant to the only effective oral treatment. The world needs another, say researchers.

A new bioluminescence imaging technique has created highly detailed, and visually striking, images of the movement of oxygen in the brains of mice. The method, which can be easily replicated by other labs, will enable researchers to more precisely stud…

Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to new research. The relationship works both ways: those with perinatal depression are also more likely to develop premenstrua…

Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists.

Biologists have uncovered a quality control timing mechanism tied to cell division. The ‘stopwatch’ function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.

Hyenas are generalist predators (and scavengers) with a broad range of prey species. They are known for hunting (or scavenging) larger mammals such as antelopes and occasionally feed on smaller mammals and reptiles. Being flexible in the choice of prey…

To woo a mate, the Albert’s Lyrebird of Australia becomes a real song-and-dance bird. Each male first chooses a stage of entangled vines, then in performance he shakes the vines as part of his courtship footwork, synchronizing each shake with the beat …

A stroke often impacts a person’s ability to move their lower body from the hips down to the feet. This leads to diminished quality of life and mental health in addition to increased susceptibility to falls. But now, researchers are exploring new treat…
