Microcapsules Act As 'Roach Motel' To Kill Harmful Bacteria
- ScienceDaily
- 08/11/25 05:25
Scientists have created tiny microscopic spheres that trap and kill harmful bacteria in a manner the scientists liken to "roach motels" snaring and killing cockroaches. The research could lead to new coatings that will disinfect common surfaces, combat bioterrorism or sterilize medical devices, reducing the devices' responsibility for an estimated 1.4 million infection-related deaths each...
Old Flies Can Become Young Moms

Treating infectious diseases while meeting escalating costs to do so continues to pose worldwide challenges, with one of the main issues being the ability to provide an adequate supply of drugs to treat infectious diseases.
New Clinical Study Will Help Doctors Assess Abnormal Bleeding
- ScienceDaily
- 08/11/25 04:20
How do you know if you bleed normally? Scientists aim to answer that question more definitively with the launch of an assessment tool designed to help physicians and researchers more accurately determine what is inside and outside the normal range of bleeding symptoms.
Drug Therapy For Premature Infants Destroys Brain Cells In Mice
- ScienceDaily
- 08/11/25 04:20
A class of drugs that are used in premature infants to treat chronic lung damage can cause damage in the brain. New research suggests the drugs may cause cognitive and motor-control problems even when they are given before birth.
Sea Level Rise Alters Chesapeake Bay's Salinity
- ScienceDaily
- 08/11/25 04:20
While global-warming-induced coastal flooding moves populations inland, the changes in sea level will affect the salinity of estuaries, which influences aquatic life, fishing and recreation.
Value Of Satellites Recognized For Conserving Wetlands
- ScienceDaily
- 08/11/25 04:20
Wetlands contribute to our lives in remarkable ways by providing food and water, controlling floods, protecting against storms and supporting biodiversity, yet they are experiencing loss and degradation on a massive scale.
Breast Cancer Incidence Among Premenopausal U.S. Women
- ScienceDaily
- 08/11/25 04:20
African-American women under the age of 40 have a higher risk of breast cancer than do white women of a similar age. White women aged 40 and older, however, have a higher incidence than black women aged 40 and older.
Predicting The Future For Patients With Severe Traumatic Brain Injury
- ScienceDaily
- 08/11/25 04:20
"How will our loved one come out of this?" After an accident that results in severe traumatic brain injury, the answer to this simple question can change everything. A new study describes the tools that are most effective at providing an objective answer to this question almost as soon as patients leave intensive...
Sicilian Plant Gene Enters British Genetic Language
- ScienceDaily
- 08/11/25 04:20
Scientists have identified a key gene that was transferred from a Sicilian plant into a close relative in Britain, showing how genetic cross-talk between species can be important for evolution.
Advanced Lung Cancer Patients See Improved, Progression-free Survival
- ScienceDaily
- 08/11/25 04:20
Patients with advanced non-small cell lung cancer whose disease has progressed following chemotherapy have a higher rate of tumor shrinkage and a longer interval before cancer progression when bevacizumab is added to standard second-line erlotinib therapy, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the...
Gulf War Research Panel Finds 1 In 4 Veterans Suffers From Illness Caused By Toxic Exposure
- ScienceDaily
- 08/11/25 04:20
At least one in four of the 697,000 US veterans of the 1991 Gulf War suffer from Gulf War illness, a condition caused by exposure to toxic chemicals, including pesticides and a drug administered to protect troops against nerve gas, and no effective treatments have yet been found, a federal panel of scientific experts and veterans concludes in a new...

FoxJ1 Helps Cilia Beat A Path To Asymmetry
- ScienceDaily
- 08/11/25 04:20
Scientists have discovered how a genetic switch, known as FoxJ1, helps developing embryos tell their left from their right. While at first glance the right and left sides of our bodies are identical to each other, this symmetry is only skin-deep. Below the surface, some of our internal organs are shifted sideways -- heart and stomach to the left, liver and appendix to the...
