Rare sperm whale fossils discovered in Panama

The discovery of rare pygmy sperm whale fossils in Panama has provided new insights into the evolution of these whales. The fossils indicate that the spermaceti organ, which plays a key role in sound generation and echolocation, was reduced in size throughout their evolution.

UNH researchers discover new method to detect most common bacteria contaminating oysters

Researchers at the University of New Hampshire have discovered a new method to detect Vibrio parahaemolyticus, a bacterium that has contaminated oyster beds and sickened consumers in the Northeast. The detection platform uses genome sequencing and analysis to identify specific genes found only in the invasive strain.

Wind bursts strongly affect El Niño severity

A new study finds that wind bursts in the western Pacific can significantly impact El Niño events and their severity. The research identifies three distinct varieties of El Niño and explains how westerly wind bursts determine which flavor will occur. This finding could help improve future predictions of these global-scale climate events.

Frog uses different strategies to escape ground, air predators

Túngara frogs exhibit different escape responses when attacked by ground versus aerial predators. They flee from snakes on the ground but move towards bats in the air, effectively undercutting their flight path. This study highlights the flexibility of prey strategies to evade predators with diverse attack modes.

The 2015 HFSP Research Grants

The Human Frontier Science Program awarded $35 million in research grants to 31 teams, with a focus on intercontinental collaborations and cutting-edge life sciences projects. Younger scientists are encouraged to participate, with an average age of 36 for Young Investigator Grant awardees.

Educated women choosing to be mothers without marrying their spouses

A study led by Benoît Laplante finds that consensual unions have become increasingly popular among higher-income groups in Latin America. University-educated women are no longer limited to having children out of wedlock, as fertility rates correlate with living in a conjugal relationship rather than its legal nature.

An improved method for coating gold nanorods

Gold nanorods are being investigated for use in biomedical applications due to their surface plasmon resonance, allowing them to absorb and scatter light. The improved method enables large-scale production and controlled shell thicknesses, paving the way for stable gold nanorods with chemically functionalized surfaces.

Insulin pumps need greater safety review

The American Diabetes Association and European Association for the Study of Diabetes call for a comprehensive safety overhaul of insulin pumps, including greater access to data from manufacturers and funding for independent clinical trials. This is crucial for healthcare teams to educate patients on preventing errors with these devices.
