Researchers have discovered that certain bacteria can prevent sperm from swimming well enough to reach an egg, affecting fertility. Infertile men with asymptomatic infections may benefit from broad-spectrum antibiotics to eliminate the bacteria before attempting IVF.
A study by UNC researchers confirms the presence of mutated, drug-resistant human immunodeficiency virus in the semen of men taking antiviral medications. The study found that if men do not have adequate suppression of their virus, they are likely to shed drug-resistant strains of HIV in their genital secretions.
Scientists have captured the most insightful images to date of Neptune's wildest weather, including monster storms and equatorial winds of 900 miles per hour. The new observations revealed a
Elevated levels of corticipotropin-releasing hormone (CRH) may predict preterm delivery and shorter gestation lengths in pregnant women. The study found that higher CRH levels at 28-30 weeks gestation were associated with earlier deliveries and increased risk of preterm birth.
Researchers have developed a mobile robot tracking system that can predict escape routes and optimize view angles to catch moving objects. The system uses laser rangefinders and 3D mapping to track targets, making it difficult for humans and robots to evade detection.
The National Library of Medicine (NLM) announces 24 contract awards totaling $2.3 million to develop innovative medical projects leveraging the capabilities of the Next Generation Internet (NGI). These projects aim to improve data transfer, security, and usability in healthcare settings.
Researchers found that women with recovered bulimia nervosa had increased serotonin levels and negative moods, obsessions with perfectionism, and anxiety. The study suggests that altered brain chemistry contributes to the development of bulimia nervosa and persists even after recovery.
Researchers have developed brain implants that allow people with severe disabilities to control a computer cursor using their thoughts. The technology has shown promise in enabling individuals with paralysis or other conditions to interact with the world, with further research ongoing to improve its capabilities.
The Whitaker Foundation has awarded more than $30 million to The Johns Hopkins University and the University of California, San Diego for biomedical engineering programs. This marks the largest individual grants in its 23-year history.
A team of scientists from Idaho National Laboratory developed a system to evaluate what's inside projectiles without opening them. The PINS technology uses neutron spectroscopy to determine the type and amount of chemical agents, enabling safe disposal and preventing accidental destruction of incinerators.
Two scientists suggest that satellites' waste heat could be causing distant spacecraft to slow down faster than expected. The heat is emitted in a direction opposite to the Sun, giving the spacecraft a small push towards the Sun and slowing them down.
