Adenomyosis — an abnormal tissue growth into the muscular wall of the uterus that causes painful cramps and heavy or prolonged menstrual bleeding — is more common than generally appreciated, a review of the literature by gynecologists revealed.

Researchers have devised an ingenious method of using acoustics to conceal and simulate objects.

Previous fires may hold the key to predicting and reducing the severity of future wildfires in the western United States as fire activity continues to increase, according to researchers.

Scientists reveal new approaches to manipulating light absorption in optical resonators by different types of optical losses.

The effects of monsoon rainfall on food insecurity in Nepal vary by earthquake exposure, with regions that experienced both heavy earthquake shaking and abundant rainfall more likely to have an inadequate supply of nutritious food, according to new res…

A team of researchers is using a novel technique to comb through the data and to reconstruct major branches in the linguistic tree.

A decades-long study of introduced voles on the Norwegian islands of Svalbard is helping to answer a longstanding puzzle of Arctic ecology — what drives the well-established population cycles of small Arctic mammals, such as voles and lemmings. These …

A new study into cognitive control promises to be the first of many aimed at understanding its origins in the brain and its variations between people and among groups.

CD8+ T cells — known as “killer” T cells — are the assassins of the immune system. Once they are primed, they seek out and destroy other cells that are infected with virus or cells that are cancerous. Priming involves dendritic cells — sentinels of …

A new silicon chip can decode any error-correcting code through the use of a novel algorithm known as Guessing Random Additive Noise Decoding (GRAND).

Researchers claim that previous calculations of ICT’s share of global greenhouse emissions, estimated at 1.8-2.8%, likely fall short of the sector’s real climate impact as they only show a partial picture. The researchers point out that some of these p…

Researchers find that machine-learning algorithms can identify effective behavioral, educational, and psychological interventions more accurately than professionals can.

Humans acknowledge that personality goes a long way, at least for our species. But scientists have been more hesitant to ascribe personality to other animals. A study has now documented personality in golden-mantled ground squirrels, which are common a…

A new conducted in both mice and a small group of patients with advanced cancers has shown that so-called ‘cold’ tumors that are nearly devoid of immune cells — and therefore unresponsive to immunotherapy — can be turned ‘hot’ with extremely low dose…

School-aged children who spend more time in front of screens are only slightly more likely to have attention disorders, disturbed sleep or lower grades and are no more likely to suffer from depression and anxiety. Meanwhile, they tend to have more clos…

Large carnivore populations are expanding across Europe and experts are calling for increased support for communities to encourage harmonious relationships with their new neighbors.

The increasing use of photoinitiators, especially in medical settings, has raised concerns about their adverse effects on human health. Now, scientists have shown that three photoinitiators — 1-HCHPK, MBB, and MTMP — show estrogen-like activity in mi…

An international team of researchers developed the largest and most detailed simulation of the Universe to date and has made it freely available on the cloud to everyone. This simulation, named Uchuu, will help astronomers to interpret results from Big…

Scientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harm…
