New drugs for bad bugs

University of Florida researchers have developed a patent-pending method to improve antibiotic development, combining testing of various drug concentrations at the site of infection with laboratory analyses and mathematical models. This approach aims to reduce the lengthy and expensive trial-and-error process that can take years.

Galaxies in motion

An international team of astronomers has measured the motion of an entire galaxy in the sky using radio telescopes. The measurements show that the galaxy moves at a speed of 190 km/s relative to our Milky Way towards the Andromeda galaxy, and provide insights into the history and future evolution of the Milky Way.

Surf's up in the solar nebula

Scientists have long puzzled over the origin of chondrules, glassy particles found in meteorites that formed in the solar nebula. New calculations suggest that spiral arms in the disk surrounding Jupiter may have generated shock waves that melted dust clumps to form these particles.

Orthodontists must brace against back pain

A new study published in Clinical Biomechanics reveals that orthodontists are at risk of musculoskeletal disorders due to prolonged sitting and repetitive tasks, with males bearing heavier loads than females. The research highlights the need for better work layout and equipment design to mitigate this risk.

New ways to ease liver disease

Research reveals that IL-6 activates a pathway in liver cells that triggers protection against hepatitis and immune-mediated liver damage. Two proteins, KC and SAA2, play a crucial role in this protective effect.

A shallow hip socket predicts osteoarthritis of the hip

A long-term study of 835 participants found moderate acetabular dysplasia to be a strong independent risk factor for hip OA. Women with acetabular dysplasia had a higher incidence and severity of hip OA, especially those with high-stress workloads and low BMI.

Important discovery about second most fatal cancer

A new syndrome of colorectal cancer has been identified, characterized by frequent mutations in the BRAF oncogene and DNA methylation. This inherited form of cancer often develops in previously harmless polyps and can occur in young individuals, emphasizing the importance of early detection and prevention.

Men more likely to get screened for prostate cancer than colon cancer, U-M study finds

A new study found that nearly two-thirds of men are up-to-date with prostate cancer screening, but only 47.6% have had a recent colon cancer screening. The researchers suggest using prostate cancer screenings as an opportunity to encourage men to get screened for colon cancer, which is projected to affect over 70,000 men this year.

Ten-minute emergency room intervention for problem drinkers

A two-hour brief negotiation intervention was developed and taught to 58 emergency room physicians, with over 90% passing the proficiency exam. The intervention helps hazardous and harmful drinkers by raising awareness of their drinking levels, enhancing motivation to reduce drinking, and negotiating a plan of action.

What the eye doesn't see

Research from University of Bristol provides strongest evidence that disruptive patterns protect insects from birds, a predator that shaped evolution of protective coloration. By varying colors, size, and location of patterns on artificial moths, the team identified effective combinations that mimicked tree characteristics.
