Researchers discovered that lisofylline treatment reduced the incidence of Type 1 diabetes in mice by 67%, indicating its potential to protect insulin-producing cells. The study published in Pancreas journal suggests that lisofylline may slow down or prevent the disease in people at high-risk.
A study found that most physical activity web sites provide general knowledge but lack personalized assistance to users. Tailored messages can increase the chance of material usage and personal change. One site, JustMove.org, outperformed others in providing interaction and tailored assistance.
Researchers found that males of iridescent butterfly species approach females producing polarized signals more often when not depolarized. Non-iridescent species show no preference regardless of filter presence. Light bending by genetic scales may influence sexual selection and speciation in tropical forests.
A study found that white college students with high racial bias experienced a decrease in executive function after interacting with black people. Conversely, those who interacted with white people showed no subsequent loss of cognitive function.
Researchers have deciphered the genome of Bacillus anthracis, a deadly soil bacterium that has been weaponized as a biowarfare agent. The analysis reveals that the bacterium's virulence is linked to specific genes and plasmids that enable it to thrive in environments rich in protein.
Daniel Crawford's work aims to prevent undesirable side effects in synthetic drugs by accurately determining molecule handedness. He is developing computer models to compute optical rotation, allowing natural-products chemists to identify the correct hand of molecules.
Scientists in Japan and UCSD have discovered a novel regulatory role for pseudogenes, which stabilizes a protein-coding gene on another chromosome. The study found that disabling the pseudogene led to abnormal kidneys and bones in laboratory mice, while re-introducing it resulted in normal development.
A study of over 300 HIV patients found that 32% reported better life after diagnosis, with fewer worries about finances or disclosure. Patients who said life was better expressed more optimism and participated in non-organized religious activities.
The Prevnar vaccine, developed at the University of Rochester, has shown remarkable real-world effectiveness in reducing invasive pneumococcal infections by 69% among children under two years old. This translates to approximately 20,000 fewer cases of infection each year in the United States.
Researchers found that ants use distinct body odors to signal tasks, such as foraging and patrolling, allowing them to coordinate complex behaviors without a hierarchical control structure. The discovery sheds light on the importance of scent in insect communication and has implications for fields like computer science and robotics.
Researchers at UCSF suggest a new cutoff point for assessing risk based on weight for gestational age, increasing the prediction of adverse neonatal outcomes. The study found that fetuses in the lowest 5th percentile are at dramatically increased risk for low birth weight and preterm birth.
The editorial emphasizes that providing affordable drugs is insufficient to combat HIV in the developing world. Comprehensive medical care, including training for healthcare workers and laboratory tests, must also be included to make Highly Active Antiretroviral Therapy (HAART) effective.
Researchers from The Institute of Genomic Research sequenced B. anthracis genome to improve vaccine design and drug development. Despite similarities with closely related bacteria, the study found unique genes giving B. anthracis its ability to thrive on protein-rich matter.
A University of Toronto geologist claims that diamonds originated on the ocean floor, supported by a new study published in Nature. The research reveals that diamond formation begins when lava is pushed onto the ocean floor, interacting with sea water to alter its oxygen composition.
Researchers found that senators' efforts to boost approval ratings have limited impact compared to contextual factors like state population, economic performance, and president's popularity. Seniority and media coverage also play significant roles in shaping senatorial approval ratings.
The decoded Neurospora genome shows that humans share genetic similarities with the common bread mold, with around 10,000 genes. This discovery could lead to advances in genetic-based medical treatments and the development of new materials.
Scientists create hybrid virus that can attach to lung cells' top surface, allowing healthy genes to enter and correct genetic defects associated with cystic fibrosis. The new approach increases production of viral particles, a crucial step towards preclinical studies.
The UC Riverside-led study unveils the genome sequence of Neurospora, a model organism for understanding fungi's role in agriculture, medicine and the environment. The research reveals 10,000 predicted genes, with significant implications for developing new antibiotics and disease control strategies.
The Cornell laboratory will be a national center for calculating earthquake effects on structures, including soil deformation and seismic damage. The facility will use customized testing structures and actuators to apply displacements and loads, enabling researchers to study the behavior of structures during earthquakes.
Researchers have discovered the structure of voltage-dependent ion channels, crucial for nerve function and muscle contraction. The study reveals a novel mechanism that enables ions to flow through these channels, allowing for precise regulation of electrical impulses in the brain and heart.
Drs. Brown and Goldstein's research on low-density lipoprotein receptors and Sterol Regulatory Element Binding Proteins (SREBPs) led to effective new drugs for high cholesterol treatment and discovery of a potential insulin-sensitive regulator for diabetes therapy.
Researchers at Whitehead Institute for Biomedical Research have discovered a protein called GβL that helps regulate the mTOR pathway. The study reveals that when GβL is absent or disabled, cells become insensitive to nutrient levels and grow abnormally, which may be a cause of disease.
A UC Davis study found that a soy extract supplement reduced PSA levels in men with untreated prostate cancer. The study involved 62 men who received genistein concentrated polysaccharide for six months, resulting in an average decrease of 17% in PSA levels.
Research found that male butterflies of iridescent genus Heliconius are attracted to female wings displaying polarized light, suggesting a new role for polarization in mate attraction. The study also highlights the importance of polarization in maintaining species diversity among tropical butterflies.
Researchers at Rockefeller University have discovered the molecular mechanism by which potassium ions flow through living cells during a nerve or muscle impulse. The structure reveals four red-tipped paddles that open and close in response to positive and negative charges.
Researchers have identified a promising drug development strategy for lupus by targeting the Tall-1 molecule. Binding studies revealed that a short section of one binding domain on Baff-R holds promise, potentially preventing lupus-like symptoms in mice and people with autoimmune diseases.
