Eat, prey, rain

Researchers developed a model that mimics three predator-prey modes to understand cloud-rain interactions, finding that aerosols affect cloud formation and precipitation. The study provides new insights into the complex relationships between clouds, rain, and aerosols, shedding light on climate patterns and human-induced changes.

Soft spheres settle in somewhat surprising structure

Researchers at Penn State have discovered that particles in liquids don't always settle at the bottom based on size or speed. Instead, they arrange themselves in a way that achieves the lowest energy state, often resulting in a layered structure with larger particles at the bottom and smaller ones above.

Battle won against Asian tiger mosquito

A combination of strategies, including eliminating stagnant water and removing vegetation, significantly reduced the number of tiger mosquito eggs in treated areas. The study, published in Transactions of the Royal Society of Tropical Medicine and Hygiene, demonstrates a substantial reduction in eggs compared to control areas.

ONR technology to aid in war on drugs

The Joint Interagency Task Force South is installing a new software technology developed by the Office of Naval Research (ONR) to eliminate illegal drug trafficking. The Command and Control Rapid Prototype Continuum (C2RPC) system provides continuous rapid delivery of warfighter capability to support time-sensitive decision making.

A*Star scientists discover how to combat hospital-acquired infections and life-threatening toxins

A*STAR scientists have discovered a potential antidote for Ricin and Pseudomonas exotoxin, two deadly toxins responsible for hospital-acquired infections. The study identified ERGIC2 as a therapeutic target, paving the way for developing generic antidotes against these life-threatening toxins.

Earliest watery black hole discovered

Astronomers have found the largest and farthest reservoir of water ever detected in the universe, located in a distant quasar with a massive black hole. The discovery provides valuable information about the early universe's water vapor behavior and its influence on cosmic evolution.

Grazing management effects on stream pollutants

A study by Iowa State University found that grazing management practices can greatly reduce the amount of sediment, phosphorus, and pathogens deposited into pasture streams. Simple and practical techniques can be implemented to minimize pollution while allowing cattle to graze on pasture stream banks.

Forest fungus factory

A University of Vermont scientist has developed a bio-pesticide using an insect-killing fungus and sweet whey to reduce the growth rate of hemlock woolly adelgid. The treatment showed promising results in trials, with a 50% reduction in pest population in infested trees.

Dolphins' 'remarkable' recovery from injury offers important insights for human healing

Researchers explore dolphins' remarkable ability to heal from shark bites with minimal pain or infection, proposing that blubber contains antimicrobial compounds. The dolphin's healing process is similar to regeneration, where tissues are knitted together with existing fabric, offering new perspectives for human injury care.

Do we buy cosmetics because they are useful or because they make us feel good?

A study by UPV/EHU shows that people prioritize emotional reasons over usefulness when buying cosmetics. Women's negative emotions about their appearance drive their purchasing decisions. The study highlights the importance of addressing these negative feelings through persuasive marketing strategies focused on emotional aspects.

Hepatitis B vaccination for health care students lags behind recommendations

A study found that only 59.8% of health care students had documentation of complete hepatitis B vaccination, while 83.8% were protected against infection when tested for antibodies. The rates are lower than the US government's Healthy People 2010 goal of 90% hepatitis B vaccination coverage among health care workers.
