A new urine test detects prostate cancer more accurately than current methods, including PSA and PCA3 tests. The test identified 80% of patients with prostate cancer and was 61% effective in ruling out disease.
A study by Paul Williams found that quitting exercise can lead to significant weight gain, especially at lower intensity levels. Resuming exercise after an hiatus is often not enough to reverse the weight gain, highlighting the importance of consistent and year-round physical activity to maintain a healthy weight.
Researchers have developed a successful test vaccine that prevents the development of prostate cancer in 90% of young mice. The vaccine targets prostate stem cell antigen (PSCA), which is over-expressed in early-stage prostate cancers, and has been shown to mount an immune response against the protein.
Researchers have created a novel process for catching gas from the environment and holding it indefinitely in molecular-sized containers, promising improvements to greenhouse gas management and fuel cell development. The 'molecular nanovalves' system is highly controllable and recyclable, allowing for safe and efficient storage of gases.
Researchers found that the M2 protein's motion and structure change when treated with amantadine, blocking the flu virus from infecting healthy cells. The study provides insight into developing alternative antiviral drugs for resistant flu strains.
The Simons Foundation's $10 million grant will support preclinical studies of new therapies for gliomas, a type of brain cancer. The goal is to develop treatments that target cancer cells and abnormal signaling pathways while sparing nearby sensitive tissues.
Researchers developed a new approach to image enhancement using PSO algorithm, which intelligently boosts contrast and detail in an image. The method outperforms existing approaches in terms of computational time and objective evaluation, making it suitable for various applications such as CCTV images and lower quality camera photos.
A new study published in Arthritis Care & Research found that taking two NSAIDs was associated with lower scores on a health-related quality of life assessment. Dual use was also linked to worse physical functioning and symptoms, highlighting the need for better pain management and patient communication.
Dennis J. McGillicuddy, Jr., a pioneer in physical-biological interactions, is recognized for his groundbreaking studies of plankton and ocean currents. His research has significantly impacted the global carbon cycle and marine ecosystem productivity.
Scientists at UAB and Saint Louis University use X-ray crystallography to understand poxvirus infectious potency and how one protein evades the immune system, paving the way for new drug discoveries to combat inflammatory diseases like atherosclerosis and rheumatoid arthritis.
The American Institute of Physics (AIP) has awarded the 2008 Dannie Heineman Prizes to Mitchell Feigenbaum for his work on deterministic chaos and Andrew Fabian for his pioneering research in X-ray astronomy. These awards recognize their significant contributions to their respective fields.
Novel molecular techniques have shed light on the nature of freshwater environments as a bacterial habitat. Researchers can now analyze specific functional capabilities of bacteria, such as their ability to metabolize particular molecules, and understand how microbial populations shift in response to environmental change.
A study published in SLEEP found that higher periodic leg movement index (PLMI) predicted less sleep at night in older people with cognitive impairment. The study, conducted by Kathy C. Richards of the University of Pennsylvania, assessed 102 participants and found that PLMI explained 43.6% of the variance in total sleep time.
The newly discovered grey-faced sengi (Rhynchocyon udzungwensis) is a large, rare species found only in two high-altitude forest blocks in Tanzania's Udzungwa Mountains. Its unique features include a distinctive grey face and jet-black lower rump, highlighting the region's exceptional biodiversity.
Researchers found that dreams after 9/11 showed more intense imagery but not longer or more bizarre content, contradicting expectations. The study suggests a link between the traumatic event and increased emotional intensity in dreams.
A study published in PLoS Computational Biology suggests that serotonin may contribute to depression and anxiety by disrupting reflexive avoidance behaviors. When serotonin levels drop, individuals lose their instinctual ability to avoid aversive events, leading to increased exploration of potentially harmful states.
A UCLA study found PET scanning more sensitive and accurate than conventional imaging methods in detecting treatment response in sarcoma patients. Standard size-based evaluation methods only identified 20% of responders, while PET accurately picked up all responders.
Researchers at the University of Wisconsin-Madison found that administering interleukin-7 during a specific stage of infection can increase the number of killer cells capable of destroying virus-infected cells, enhancing immune memory. This discovery may lead to improved vaccine efficacy against HIV and cancer.
Researchers at Columbia University Medical Center have discovered a brain region that can be stimulated to reduce cognitive deficits associated with sleep deprivation. The study used repetitive transcranial magnetic stimulation (rTMS) to improve working memory performance in young adults after extended sleep deprivation.
Scientists have determined the three-dimensional structure of human kynurenine aminotransferase II, an enzyme regulating glutamate activity. The discovery provides insight into biochemical regulation and may lead to treatments for neurodegenerative diseases like Parkinson's and Alzheimer's.
Researchers have discovered a crucial role for heparan sulfate in regulating embryonic stem cell potency, while also uncovering the mechanism behind SARS lung damage. The structures of key enzymes involved in these processes are now understood, opening up new avenues for treatment and drug development.
