Predatory bacterial crowdsourcing

Scientists at Rice University and UTHealth discovered a simple formula that enables Myxococcus xanthus bacteria to create waves to spread and devour other bacteria. The formula involves side-to-side contact between cells, a reversal time interval, and physical interactions, allowing the waves to move outward in unison.

Scaling up polymer blobs

Researchers used simulations to study the scaling behavior of polymers at extreme limits, where it depends on their density and length. They found that polymer blends in ultrathin films displayed enhanced compatibility due to the simulations' ability to efficiently compute dense large-chain systems.

Breakthrough for new diabetes treatment

Researchers at Karolinska Institutet have made a major breakthrough in type II diabetes treatment by inhibiting VEGF-B. The study shows that VEGF-B inhibition can prevent and treat insulin resistance, which is related to the storage of fat in muscles, blood vessels, and heart.

Researchers examine bias among sports journalists on Twitter

A Clemson University and University of Louisville study found that sports journalists used Twitter to post biased commentary during the Penn State sex abuse scandal, blurring personal and professional boundaries. The research highlights the challenges of maintaining objectivity in social media news reporting.

Treating hepatitis C infection in prison is good public policy

A recent study found that treating hepatitis C in prison can be just as effective as treatment for non-incarcerated patients, with 43% of prisoners achieving a sustained viral response. The research highlights the importance of providing antiviral therapy to incarcerated individuals to curb the spread of hepatitis C.

Honey bees fight back against Varroa

Researchers discovered specific proteins in honey bees that help them resist Varroa mite infestations. These proteins enable the removal of infected larvae and reduce mite populations, promoting the survival of the species. This natural approach could provide a solution to Colony Collapse Disorder.

Hummingbirds make flying backward look easy

Researchers discovered hummingbirds' reverse flight is cheaper than hovering and equally costly to forward flight, employing unique kinematic adjustments. The study found that the birds reduce wing beat frequency and inclination during backwards flight, making it 20% more efficient.

Rutgers College of Nursing professor's research links increased hospital infections to nurse burnout

A recent Rutgers study found that increased nurse burnout is associated with higher rates of hospital-acquired infections, such as urinary tract and surgical site infections. By reducing burnout levels from 30% to 10%, researchers estimate a potential prevention of 4,160 infections and an estimated savings of $41 million.

Singing in the brain

A Concordia researcher is developing a system that converts physiological displays of emotion into music. The music is used to teach individuals with autism disorders how to identify feelings by externalizing them through sound. By tapping into the brain's electrical signals, researchers can create an emotional symphony.

Retweeted health messages may not be what the patient ordered

A study by Penn State researchers found that people perceive tweets and retweets differently depending on the source, with original tweets from popular doctors being most credible. Non-medical professionals with a large following were also seen as more trustworthy than doctors who retweet health messages.

Moffitt Cancer Center researchers say smoking relapse prevention a healthy step for mothers, babies

A study by Moffitt Cancer Center researchers found that a series of ten self-help booklets helped nearly 70% of pregnant women remain smoke-free after giving birth. The booklets provided detailed information on quitting cigarettes during and after pregnancy, with varying effects based on household income and age.

Viewing gender-specific objects influences perception of gender identity

Researchers found that viewing objects associated with one gender can make viewers perceive an androgynous face as being of the opposite gender. The study suggests two possible explanations for this effect, including common brain regions involved in identifying both types of stimuli and a higher cognitive function of adapting to gender.
