Young infants with fever may be more likely to develop infections

Researchers found that young infants with fevers are more likely to develop serious bacterial infections. Infants under eight weeks old have a doubled risk of developing such infections. Parents are encouraged to seek immediate medical attention if their child develops a fever over 100.4 degrees Fahrenheit.

Costs of natural disasters are increasing at the high end

The economic cost of natural disasters has increased disproportionately for major events like hurricanes and tornadoes, while lesser events have seen less growth. Climate change is driving these increases, with the top 1% of damages estimated to rise by $26 million annually.

Daddy daycare: Why some songbirds care for the wrong kids

Scientists have observed a rare instance of interspecific feeding among songbirds, where an adult male Eastern bluebird is caring for the young of another species, the tree swallow. The unusual behavior is thought to be caused by the bluebird's confusion and 'place-based decision' to care for the wrong chicks.

Hovering closer to the secrets of hummingbird flight

A team of researchers is working on understanding the agility of hummingbirds to develop robotic systems that can mimic their complex escape maneuvers. By studying the aerodynamics, perception, motion planning, and control of hummingbird flight, the team hopes to create robots that can achieve high agility in fluid environments.

Jumping the gap may make electronics faster

Researchers have developed a method to transfer information using surface plasmon polaritons (SPPs), enabling faster signal propagation in microelectronic chips. The technique, which uses multiple snapshots of electromagnetic fields, can potentially solve the problem of shrinking electronic components and improve the speed of chips.

Eating cheese may offset blood vessel damage from salt

A recent study published in the Journal of Nutrition found that consuming four servings of cheese per day alongside a high sodium diet may protect blood vessels from damage. The researchers discovered that antioxidants in cheese may play a role in preserving vascular health, providing an alternative strategy to reduce cardiovascular risk.

Papillomaviruses may be able to be spread by blood

A recent study found that rabbit and mouse papillomaviruses can be transferred by blood to their respective hosts, raising the possibility of human papillomavirus (HPV) transmission through blood in humans. The researchers also detected HPV sequences in mucous membranes like the tongue and genitals, as well as in the stomach.

Gene therapy helps functional recovery after stroke

Researchers have developed a new gene therapy that converts glial cells into neurons, improving motor function in mice and potentially treating stroke. The treatment uses the NeuroD1 gene and has been shown to increase neuronal density and reduce brain tissue loss in mouse models of stroke.

Livestock disease risk tied to herd management style

A new study reveals that livestock managed in a system where they are the sole source of an owner's livelihood are more likely to become infected with PPRV. Herds from pastoral villages had 3.8 times the risk of becoming infected compared to agropastoral villages.

Moving faster in a crowd

New research shows that particle transport in crowded cells can be faster than in non-crowded environments, especially when moving from densely crowded areas to less crowded ones. The study used microfluidics and tracer colloids to investigate the effects of non-uniformly distributed crowding molecules on particle movement.

Data assimilation method offers improved hurricane forecasting

A new approach developed at Penn State's Center for Advanced Data Assimilation and Predictability Techniques can accurately forecast the intensity and trajectory of Hurricane Harvey. The method uses data from the GOES-16 satellite and Penn State's all-sky radiance technique, which more accurately models hurricanes.

How many Earth-like planets are around sun-like stars?

A new study provides the most accurate estimate of the frequency that planets similar to Earth occur around sun-like stars, which will be important for designing future astronomical missions. The researchers' novel approach allows them to account for several effects not included in previous studies.

Marijuana may boost risky effects of drinking alcohol

A new study from Penn State found that simultaneous alcohol and marijuana use is associated with heavier drinking, more frequent consumption, and higher levels of sensation-seeking characteristics. Individuals who used both substances simultaneously were also more likely to experience alcohol-related problems.

How we care for the environment may have social consequences

Researchers found that men and women were more likely to question each other's sexual orientation if they engaged in non-conforming environmental behaviors. Women were also more likely to avoid men who preferred masculine behaviors. The study highlights the social consequences of gendered pro-environmental behaviors.
