The Bush administration is considering implementing a pro-life policy that would restrict foreign non-governmental organizations from receiving US funds if they provide abortions or lobby for abortion liberalization. This policy threatens the $15 billion HIV/AIDS fund, which relies on local clinics providing family-planning and materna...
Researchers have discovered a new tool that shows how dividing cells complete the final stage of cell division with precision. Blebbistatin inhibits a type of myosin necessary for cytokinesis, revealing its essential role in human biology and cell division.
A postnatal home-visiting service for teenage mothers aged under 18 years was shown to reduce adverse health outcomes of their children, including infant deaths and foster care placements. Home visits also increased mothers' contraceptive use, but not breastfeeding or vaccination knowledge.
A new field-tested algorithm for dementia diagnosis can predict 94% of cases in less-developed countries. The algorithm is culturally and educationally sensitive, using measures translated into most languages used in the developing world.
Despite preferring virtual colonoscopy due to its less invasive nature, patients generally dislike the bowel preparation required for both tests. The study found that most patients reported little pain or difficulty with either procedure, but many expressed discomfort with the advance bowel preparation.
Researchers at WashU Medicine discovered a novel molecule that plays a critical role in gut immunology and interacts with mucosal-associated invariant T cells. The findings suggest that this molecule may be involved in various diseases of the gut, particularly those related to intestinal microorganisms.
Researchers found that Arctic clouds and climate conditions produce a cooling effect, possibly offsetting global warming's effects. Cloud forcing, which depends on interactions among climate factors, played a crucial role in this process.
The new center at Dana-Farber will conduct therapeutic antibody research, providing high affinity human single-chain antibodies to support cancer research globally. Marasco's laboratory has constructed a large phage display library to quickly isolate antibodies against various cancer targets.
A new study found that global warming could lead to abrupt changes in climate and sea level, with potential societal disruptions. The researchers discovered an Antarctic melting event that raised sea levels by 70 feet in under 500 years, causing widespread warming in the Northern Hemisphere.
The SIRTF is designed to peer into deep regions of the universe not visible optically, providing clues to star and galaxy formation. With its infrared spectrograph, it will observe ultrafrigid stars and penetrate obscuring dust in the cosmos.
Charles J. Sherr and Dennis J. Slamon are being honored with the Landon-AACR Prizes for Cancer Research, recognizing their significant contributions to understanding mechanisms of cell growth control and developing targeted cancer therapies.
A new study identifies a genetic marker in blood samples that may indicate an increased risk of colon cancer. The researchers found that individuals with a family history of colon cancer, polyps, or personal history of the disease were more likely to have this marker in their blood.
A study found that less than 20% of patients read the information sheet before giving consent, highlighting the need for verbal communication supported by written information. Patients with limited educational background had difficulty understanding the information sheet.
Researchers have discovered a way to control 'badly' behaving neurons in Parkinson's disease, potentially easing symptoms and progression. By blocking potassium channels or eliminating the subunit using gene therapy, high-frequency spiking can be stopped, preserving normal neuronal activity.
The SNAP process creates high-density nanowire lattices with reported junction densities exceeding 1011 per square centimeter. Researchers can deposit wires out of almost any material and transfer them onto substrates for various applications, including molecular switches, sensors, and magnetic storage devices.
A team of researchers found a unique population of chimpanzees in the Goualougo Triangle that have had minimal or no contact with humans. The primates displayed curious behavior when encountered, but showed no signs of fear or aggression, suggesting they had not formed negative associations with human presence.
Research at University of Pennsylvania School of Medicine found that sleeping six hours or fewer per night leads to significant cognitive performance deficits. Even if individuals don't feel overtly sleepy, chronic sleep restriction can impair neurobiological functioning and increase the risk of accidents.
This year's AACR honorees have made significant advances in understanding and treating cancer. The winners include Mario R. Capecchi, Ronald A. DePinho, Carlos L. Arteaga, Malcom F. Stevens, Martin J. Blaser, David S. Alberts, Graham A. Colditz, Janet D. Rowley, who will receive awards for their outstanding research in various areas of...
Researchers have discovered that spherical crystals develop unique 'scar' defects to compensate for the curved surface, allowing them to pack in place. The findings, supported by experiments with water droplets and tiny beads, provide insights into how such structures form and persist in nature.
