Myxococcus xanthus bacteria evolved the ability to swarm socially on soft agar without filamentous appendages (pili), relying on an enhanced adhesive matrix composed of fibrils. This cooperative behavior depends on individual cells contributing to a public commons, enabling efficient swarming and cooperation.
A team of scientists will search for marine organisms with potential to cure human maladies such as cancer and AIDS-related infections in the Gulf of Mexico. They will also explore abandoned oil rigs and an ancient shoreline, cataloging diversity of organisms and collecting new species.
The Virginia Bioinformatics Institute is at the forefront of a new regional center of excellence for biodefense and infectious disease research. This initiative aims to combat infectious diseases, including potential bioterrorism threats, by leveraging genomics, bioinformatics, and supercomputing capabilities.
A recent UC Riverside study found that mosquito coils in Indonesia and Asian markets contain the banned substance S-2, which can cause exposure to bischloromethyl ether, a potent lung carcinogen. The researchers plan to measure levels of BCME in indoor environments where the coils are used.
A study conducted at the University of Melbourne found that smoking is significantly linked to osteoporosis in women, particularly after menopause. Continuing high exposure to tobacco and greater sensitivity to smoking-induced bone loss are possible explanations for this link.
Researchers evaluated rice varieties for their allelopathic potential, finding that certain parts of the plant can inhibit barnyardgrass growth. This study suggests the possibility of developing rice-based natural herbicides to improve weed control.
Researchers found that a significant portion of folic acid is poorly absorbed by the body due to its conversion into the monoglutamate form, affecting overall absorption rates. The study suggests increasing dietary advice or product formulations with more easily absorbable forms of folic acid could help address this issue.
UCSD graduate student Vincent Leung designed a revolutionary Ultra-Low-Power SiGe BiCMOS Transmitter IC for 3G W-CDMA mobile phones. The innovative chip reduces power consumption by utilizing a smart, adaptive bias scheme and high-speed digital logic.
The University of Georgia has received a $6.7M grant to develop technologies for mapping the glycome of stem cell lines established by Bresagen. This research will lead to the isolation of specific nerve cells for Parkinson's treatment and new ways to diagnose and treat cancer.
Jane Lubchenco, a leading marine ecologist, has received the Scripps Nierenberg Prize for Science in the Public Interest. The prize honors her work promoting ocean sciences and preserving all living things in our oceans.
Scientists have discovered that cells can adapt to survive without oxygen, a key finding that could lead to new treatments for cancer, heart attack, and stroke. Researchers are tracing the signaling pathways for cell injury and death, with hopes of identifying therapeutic tools to switch cellular behavior.
The Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE) trial will study the effect of statins on preventing buildup of fat in arteries. The trial aims to find a new method of preventing cardiac disease in lupus patients.
Researchers developed a model to calculate movements of both sand and mud in tidal areas, revealing locations with little sedimentation due to quick water flow. The model can predict the effect of human intervention in tidal waters, addressing questions about released polluted mud layers and ecosystem changes.
A comparative cross-sectional survey found an unsavoury link between DTCA and the number of prescriptions. The authors warn that unregulated advertising could lead to increased drug sales and costs for the medicare program. Canadian Medical Association Journal editors highlight the need for strengthened regulation.
Families moving from high-poverty neighborhoods to lower-income areas saw significant improvements in mental health, with reduced symptoms of distress and depression. The study found no such benefits for those staying in public housing in very poor neighborhoods.
A study by the University of Iowa and Michigan found that defibrillators in high-risk locations, such as hospitals and airports, are cost-effective. However, low-risk sites like schools and hotels are not economically viable options due to low usage rates.
Researchers have successfully created carbon nanotubes with ideal photon emission, a narrow and steady emission that can be used for quantum cryptography and single-molecule sensors. This breakthrough enables the development of practical applications in fields such as quantum optics and biology.
