Newly developed photoacoustic microscopy uses vibrations generated when light is absorbed and captures images of cells or blood vessels. This development has increased the possibility of peering inside the body without contrast agents. However, obtaining super-resolution images has been limited due to the difficulty of focusing light into a small, single point with a lens. Recently, a POSTECH research team […]

Black, Indigenous and other women of color who were pregnant or gave birth during the pandemic said these experiences were overshadowed by isolation, confusion and fear, much of it caused by unclear or frequently changing institutional policies, according to a new study. Women from across the U.S. who participated in online focus groups said medical providers' COVID-19 safety protocols and […]

Financial stress due to the COVID-19 pandemic took a distinct toll on adolescent mental health and contributed to depressive symptoms, according to a new study by researchers at Children's Hospital of Philadelphia (CHOP). The study, published today in The Lancet Regional Health – Americas, found the effect was most pronounced in low-income adolescents but also affected all income groups who […]

Reproductive health experts consider hormonal contraceptives good choices for adolescents because they’re safe and highly effective at preventing pregnancy, but one aspect of their effect on the teenage body remains a mystery — whether and how they modify the developing brain. New research in young rats links the synthetic hormones found in birth control pills, patches and injections with disordered […]

LOUISVILLE, Kentucky — Patients with chronic spontaneous urticaria (CSU) who experienced a suboptimal response with 12-week omalizumab treatment showed benefit with longer treatment duration or up-dosing of the monoclonal antibody, a study found. Benefit associated with longer treatment duration or up-dosing was observed in patients with low immunoglobulin E (IgE) and high body mass index (BMI) at time of treatment […]

A program aimed at improving the city’s response to mental health emergencies has slid backward since its initial launch, with response times getting slower, more people sent to hospitals and stepped-up police involvement in cases. The program, the Behavioral Health Emergency Assistance Response Division, or B-HEARD, was aimed at reducing friction in crisis situations by sending trained professionals instead of […]

Everyone ages at a different pace. That’s why two 50-year-olds, despite living the same number of years, may have different biological ages — meaning that a host of intrinsic and extrinsic factors have caused them to age at varying paces with different levels of risk for disease and early death. Lifestyle choices, such as diet and smoking, and illness all […]

A major study has shown that health care and social assistance workers are twice as likely to file a workplace compensation claim for psychological injuries, compared to a similar data-set of workers in all non-health care industries, including construction, retail and law-enforcement services. The in-depth study of deidentified data from more than 200,000 workers is supported by three leading Australian […]

The method by which a baby was delivered is associated with how its immune system will respond to two key childhood vaccines, research suggests. Babies born naturally were found to have higher antibody levels, compared with those born via Caesarian section after receiving their jabs that protect against bacteria that cause lung infections and meningitis. Experts say the findings could […]

Tucked underneath the brain’s outer, wrinkly cortex is a deeply mysterious area, known as the claustrum. This region has long been known to exchange signals with much of the cortex, which is responsible for higher reasoning and complex thought. Because of the claustrum’s extensive connections, the legendary scientist Francis Crick, PhD, of DNA-discovery fame, first postulated in 2005 that the […]
