Neutron-star merger yields new puzzle for astrophysicists

Astronomers studying the aftermath of a distant neutron-star merger are puzzled by the continued brightening of its afterglow, which defies initial expectations. New X-ray observations suggest a more complex emission process, potentially involving a hot 'cocoon' around a jet that shock-heated surrounding debris.

Research reveals atomic-level changes in ALS-linked protein

A team of researchers has described atom-by-atom changes in a family of proteins linked to amyotrophic lateral sclerosis (ALS), a group of brain disorders. The study suggests that small chemical changes can lead to big changes in assembly and disease-associated aggregation, offering new insights into disease mechanisms.

Babies' babbling betters brains, language

New research shows that babies' babbling has a significant impact on their language development, with mothers responding more often to speech-like sounds. The study found that infants who babble more effectively learn words and vocabulary earlier in life, highlighting the importance of social feedback in language acquisition.

Default setting in electronic medical records 'nudged' emergency department physicians to limit opioid prescriptions to 10 tablets

A new study published in the Journal of General Internal Medicine found that implementing a default option for lower opioid tablet quantities in electronic medical records increased compliance with prescribing guidelines, resulting in fewer prescriptions written for larger quantities.

Scientists shed light on a key molecular mechanism of autoimmune and inflammatory diseases

A study published in Immunity reveals that the immunomodulatory cytokine IL-23's pro-inflammatory activity critically depends on structural activation of the cytokine by its receptor, IL-23R. The findings provide new insights into autoimmune and inflammatory diseases such as psoriasis, rheumatoid arthritis, and Crohn's disease.

Study: Patients benefit from one-on-one PT education before joint replacement

A study at Hospital for Special Surgery found that patients who received one-on-one physical therapy education and access to a web-based microsite prior to joint replacement surgery achieved physical therapy goals more quickly. This personalized approach improved their outcomes, including reduced hospital stay and increased confidence.

Small but fast: A miniaturized origami-inspired robot combines micrometer precision with high speed

The milliDelta robot overcomes the miniaturization challenge of Delta robots, operating at millimeter scale with high speed and precision, making it suitable for micromanipulation tasks in manufacturing and medicine. Researchers demonstrated its potential as a hand tremor-cancelling device and explored its use in retinal microsurgeries.

Majority of US physicians say they're burned out or depressed

A recent Medscape report found that nearly two-thirds of US physicians experience burnout or depression, with higher rates reported by women and mid-career physicians. The majority of physicians cited their work as the cause of their feelings of depression, which can impact patient care and relationships.

Microwaves could be as bad for the environment as cars suggests new research

A new study by the University of Manchester reveals that microwaves emit significant amounts of carbon dioxide equivalent to 6.8 million cars annually in the EU. The research also found that microwaves consume substantial electricity, equivalent to three large gas power plants, and contributes to resource depletion and climate change.

Uncovering decades of questionable investments

Researchers at University of Texas at Austin analyzed 40 years of stock prices, finding that high-beta stocks do not outperform those with low betas. Controlling for lottery-like characteristics, the seminal theory is empirically supported, revealing price pressure from investors as the main cause of the anomaly.

First surface-based estimation of the aerosol indirect effect over China

Ground-based measurements over southeastern China reveal significant aerosol indirect effects, but satellite studies have large uncertainties due to inherent limitations. The study provides a comprehensive investigation into the AIE and highlights the importance of using ground-based measurements for accurate quantification.

Will there be enough public health workers when baby boomers retire?

Researchers estimate that nearly one quarter of the governmental public health workforce plans to leave or retire in coming years. While there are enough highly-educated students to meet this challenge, concerns remain about the sector's ability to compete with private sector for qualified candidates.

How living systems compute solutions to problems

Research at the Santa Fe Institute shows that living systems use collective computation to make decisions, with individuals contributing their own opinions and preferences. The system can produce accurate distributions of power, even in complex environments like primate social groups.
