New immuno-pet tracer superior to FDG PET in predicting PD-L1 expression in head and neck cancer

Exposure to high levels of the body's primary stress hormone—cortisol—in preterm fetuses can disrupt normal heart development, potentially increasing the risk of cardiovascular disease in later life.

A single pellet of recycled plastic can contain over 80 different chemicals. A new study by researchers from the University of Gothenburg and Leipzig shows that recycled polyethylene plastic can leach chemicals into water, causing impacts on the hormone systems and lipid metabolism of zebrafish larvae.

A team of researchers from Toho University has uncovered a potential new use for a naturally occurring compound, schisandrin A, found in the traditional Chinese medicinal plant Schisandra chinensis.

Scientists have found a way to use the bacteria E. coli to convert plastic waste into a popular painkiller, a study said Monday, though outside experts doubted the technique would make a dent in the fight against plastic pollution.

Although we know sleep is essential to our physical and mental well-being, it remains an incredibly enigmatic behavior, scientifically speaking. Researchers at the University of Michigan, however, may have developed a new hypothesis to account for one of sleep's looming mysteries.

The International Osteoporosis Foundation (IOF) Bone and Cancer Working Group has released a comprehensive review detailing the often under-recognized impact of modern anti-cancer treatments on bone health.

The nation's major health insurers are promising to scale back and improve a widely despised practice that leads to care delays and complications.

Most of us know what it feels like to be in awe—whether it's watching a sunset, holding your baby for the first time, or experiencing a powerful spiritual moment. Awe is that feeling of wonder or amazement when something seems bigger than us. But it is not always easy to describe.

New guidelines, developed and led by experts at the University of Nottingham, will help clinicians to better treat the symptoms of inflammatory bowel disease (IBD) more accurately and more quickly.

In a significant leap forward for successful cancer surgery, researchers at the University of Missouri and collaborators have developed a new imaging probe to help surgeons more accurately identify and remove aggressive tumors during operations.

Mabel Ramos's favorite song is "Ghostbusters" by Ray Parker Junior. From morning until night, if Mabel is awake, she is listening and dancing to—or asking to listen to—the number one Billboard hit from 1984. Though some parents might be annoyed by listening to a single song repeatedly, her father, Mark Ramos, said he is delighted by his daughter's ability to dance, communicate and express her enthusiasm.

For the first time, a new PET imaging technique has successfully visualized three radiotracers in a single scan, according to findings presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting. This innovation in multiplexed PET offers the potential to deliver a more comprehensive molecular profile of disease, enabling greater precision in both diagnosis and therapeutic assessment.

A new drug called amycretin has shown it can help reduce body weight in two early-phase clinical trials. The drug, which targets both GLP-1 and amylin receptors to help control blood sugar and appetite, was reported to reduce body weight by up to 24.3% when injected over 36 weeks, and 13.1% when taken orally over 12 weeks.

A major new report into the lifecycle of medicines in the U.K. is published today (23 June 2025), which offers fresh insight into how medicines can better meet the needs of the people who develop, prescribe, and take them.

With the emerging trend of using anesthesia or sedation for lengthy tattoo sessions, the American Society of Anesthesiologists (ASA) has issued new guidance urging caution to emphasize that these procedures should meet the same safety standards as any elective surgery or procedure.

A cutting-edge brain imaging platform that integrates upright PET scanning, an augmented reality (AR) headset, and motion tracking enables researchers to study brain function in a more natural and dynamic way. Presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting, the new system—called Motion-tracked Immersive functional PET (MIf-PET)—allows participants to sit upright and interact with immersive tasks during scans. This approach offers a more realistic view of brain activity and holds promise for earlier and more accurate detection of cognitive disorders such as Alzheimer's and Parkinson's disease.

How Australian pregnant women are tested for gestational diabetes is set to change, with new national guidelines released today.

As of 17 June 2025, there have been over 4,000 confirmed cases of mpox and 25 deaths in Sierra Leone, raising the possibility that the virus will spread to neighboring countries and spark a larger outbreak throughout the densely populated region of west Africa. Cases in Sierra Leone appear to be spreading from person to person, mainly among young men and women.
