Scientists report new approach to reduce or prevent renal fibrosis

Researchers have discovered a potential new treatment for renal fibrosis by selectively activating AT1 receptors on T cells, which may help limit scar formation in the kidney. The study found that activating these receptors mitigates renal fibrogenesis by inhibiting Th1 differentiation and renal accumulation of pro-fibrotic macrophages.

Microscopy in the body

Biotechnologists and medical researchers at FAU have developed a miniaturized multi-photon microscope that can be used in endoscopes, illuminating the body's own molecules to enhance imaging. This technology offers high-resolution three-dimensional images of living tissue, supplementing or even making biopsies superfluous.

'Lovely' and 'scientific' -- Medical student evaluations differ by gender and minority status

Researchers analyzed over 90,000 narrative medical school evaluations, finding significant differences in how female and underrepresented minority students are described. Evaluators often used personal descriptors to describe performance, with strikingly different words for men and women. The study also identified biases in descriptive...

NASA study verifies global warming trends

A NASA study has verified recent global warming figures, showing high consistency between satellite-based AIRS data and station-based GISTEMP analysis over the past 15 years. The findings also suggest that surface-based data may be underestimating temperature changes in the Arctic, indicating faster warming at the poles.

Student teams use O.R. and analytics to help GM introduce new autonomous vehicles to fleet

In the INFORMS O.R. & Analytics Student Team Competition, student teams from around the world used operations research (OR) and analytics to optimize autonomous vehicle delivery processes for General Motors. The winning team from Korea Advanced Institute of Science and Technology minimized total costs while satisfying all constraints.

Study finds natural variation in sex ratios at birth and sex ratio inflation in 12 countries

A new estimation method for assessing natural variations in the sex ratio at birth was developed by an international team of researchers. The study found regional baseline SRB imbalances and identified 12 countries with strong evidence of sex ratio inflation, leading to fewer female births than expected.

PCORI Board approves $45 million to support research on opioid use disorders, cancer pain

The Patient-Centered Outcomes Research Institute (PCORI) has approved $44.6 million to fund studies comparing the best ways to treat health conditions that impose high burdens on patients, caregivers, and the healthcare system. The newly approved awards focus on improving treatment for opioid use disorder (OUD), with a total of four aw...

At last, acknowledging royal women's political power

A recent study analyzing eight premodern states reveals that queen rulers and main wives exercised significant political power, including determining succession, governing policies, and influencing alliances. These women often wielded comparable power to their male counterparts, with agency extending beyond warfare.
