'Anxious Monday' effect: Chronic stress hormone surge linked to start of week in older adults

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.

An article published in the journal Nature Metabolism presents an experimental drug that stimulates adipose tissue cells to produce heat through a process known as thermogenesis, thereby promoting weight loss.

Pain is easy to understand until it isn't. A stubbed toe or sprained ankle hurts, but it makes sense because the cause is clear and the pain fades as you heal.

Lack of access to healthy food is a threat to the lives of cancer survivors—a significant and often overlooked factor affecting their long-term health outcomes. A new study shows that those experiencing food insecurity had a 28% relative increase in risk of death as compared to those who were food secure.

Two newly developed PET imaging agents have been proven effective in identifying the histamine H3 receptor (H3R) that is highly expressed in neurological and psychiatric conditions. The novel agents have a long half-life, addressing key limitations of existing tracers and offering the potential to enable broader clinical imaging of H3R. This research was presented at the 2025 Society of Nuclear Medicine and Molecular Imaging Annual Meeting. The abstract is published in the Journal of Nuclear Medicine.

Amyotrophic lateral sclerosis (ALS) is a fast-progressing neurodegenerative disease with an average survival time of three years and no effective treatments. In ALS, motor neurons in the spinal cord, which are required for muscle contractions, die off, leading to progressive muscle paralysis.

A new multi-cohort study at Columbia University Mailman School of Public Health has found that exposure to certain metals, detected in urine, is associated with a higher risk of heart failure (HF).

Hepatocellular carcinoma (HCC), the most common type of liver cancer and the third-leading cause of cancer-related deaths worldwide, is extremely challenging to treat. However, the future of HCC patient care looks brighter thanks to research led by Devanand Sarkar, M.B.B.S., Ph.D., who—with his research team—discovered that the gene TAF2 plays a pivotal role in the growth of this cancer.

Two major systematic reviews led by the University of Bath's Center for Motivation and Behavior Change and published in the International Journal of Behavioral Nutrition and Physical Activity suggest that the quality of neighborhoods and social connections plays a bigger role than access alone in explaining why older adults in wealthier communities are more physically active.

On June 24, 2022, the U.S. Supreme Court decision in Dobbs v. Jackson Women's Health Organization eliminated a nearly 50-year constitutional right to abortion and returned the authority to regulate abortion to the states.
