A new study provides the best evidence to date that the connection patterns between various parts of the human brain can tell scientists the specialized functions of each region.... Read more

Organ donation following medical assistance in dying (MAiD), also known as euthanasia, is a relatively new practice both in North America and worldwide. A first comparison of liver transplantation using organs donated after MAiD in Canada has shown good patient survival with outcomes similar to standard donation after circulatory death.... Read more

Many clinical trials exclude women who are pregnant, breastfeeding, or able to become pregnant. This is often done to protect the health of unborn babies and infants, but it means there is little reliable information about how medicines and treatments affect these women and their babies, according to a Viewpoint...

Tooth development is a dynamic process that involves the stages of the bud, the cap, and the bell, followed by root development and subsequent tooth formation. Processes such as the bud-to-cap transition are mediated by epithelial-mesenchymal interactions. In addition, the position of a cell in a developing embryo determines its... Read more

Grape seed extract—a dietary supplement made from the seeds of wine grapes—has been investigated to see if it can help reduce blood cholesterol levels and high blood pressure. But can it also help slow down the growth of prostate cancer in men who have already undergone treatment?... Read more

A prospective study conducted at Avicenna University Hospital (Cadi Ayyad University) suggests that the plethysmographic perfusion index (PPI), a noninvasive parameter derived from pulse oximetry, can help identify fluid responsiveness in critically ill patients with acute circulatory failure. The research is published in the Journal of Intensive Medicine.... Read more

Researchers at the Francis Crick Institute have found that hunger can make virgin female mice aggressive towards pups, but only in certain hormonal states. These mice would usually ignore other females' pups or show parent-like caring behavior.... Read more

A study published in the journal CABI One Health has revealed major inequalities in One Health research.... Read more

Lab-based studies have provided lots of information on the biology of aging, but it's unclear how lab discoveries apply to aging in the real world. Research in Aging Cell provides insights into aging based on studies in dogs.... Read more

The technique sounds so outlandish that it won an IgNobel prize in 2024. But the science behind rescuing people with blocked airways and clogged lungs by rectally delivering oxygen to the body is no joke.... Read more

Amid the escalating threat of climate change, environmental degradation and pandemics, global health depends more than ever on coordinated, cross-sectoral action. It's why a growing number of researchers, practitioners and institutions are embracing One Health, a cooperative model that recognizes the interconnections between human, animal, and environmental health....

Nurse Rod Salaysay works with all kinds of instruments in the hospital: a thermometer, a stethoscope and sometimes his guitar and ukulele.... Read more

A new 3D human brain tissue platform developed by MIT researchers is the first to integrate all major brain cell types, including neurons, glial cells and the vasculature into a single culture. Grown from individual donors' induced pluripotent stem cells, these models—dubbed Multicellular Integrated Brains (miBrains)—replicate key features and functions... Read more

Pulmonary fibrosis is a deadly disease in which the lungs become thickened and scarred, gradually losing their ability to deliver oxygen to the body. Now, scientists at UC San Francisco have identified a key cellular switch that drives this process—and found a way to block it in mice.... Read more

The idea that building better health care systems can improve and save people's lives may seem obvious, but until now there has been little published with the data and statistical muscle to prove it.... Read more
