Researchers at Michigan Tech have developed a new sun-driven process to create liquid methanol from methane, a plentiful but often wasted gas. The process uses near-UV light and a titanium-based catalyst, promising to make natural gas more commercially viable and reduce emissions.
Researchers found that HIV can infect cells lacking the CD4 receptor by forming a receptor complex with co-receptors like CCR5 or CXCR4. This expands the range of potential targets for drug therapies aimed at preventing HIV spread.
Research reveals that the AIDS virus in cerebrospinal fluid evolves independently of the virus in the blood, leading to two genetically distinct forms. This finding suggests that drugs effective against HIV-1 in blood may not be effective in the central nervous system, and vice versa.
The future health requirements of tomorrow's older population will significantly impact their quality of life, with millions expected to be poor and frail. Investing in aging research is crucial to prevent debilitating conditions and reduce healthcare costs.
Moderate wine consumption is linked to a healthier diet and reduced incidence of ischemic heart disease. A study of 48,763 Danish men and women found that moderate wine drinkers (1-3 glasses/day) consumed the most heart-healthy diet.
A study at Brown University found that 'bad' brain experiences can lead to stronger connections and improved brain function during infancy. Researchers tested the effect of eyelid closure versus blocking electrical activity in one eye on neural connections, finding that eyelid closure caused more severe weakening.
A study found that US natural disaster planning is poorly implemented, with only 20% of available funds spent on mitigation projects. Researchers recommend improving hazard reduction planning through infrastructure development, land use planning, and environmental protection.
Indigenous leaders, scientists, and policy makers from 10 countries will gather in Finland to discuss the impact of human activity on Arctic caribou and reindeer communities. The goal is to develop a comprehensive plan for scientific research that promotes the well-being of Arctic residents and reduces conflicts over resource use.
Researchers discovered that human stem cells use a specific receptor, CXCR4, to migrate to bone marrow. Treating stem cells with growth factors increased their ability to express this receptor and migrate successfully, improving transplant success rates from 25% to over 90%.
A new study finds that certain brain cells can be stimulated to regenerate following a stroke, potentially treating memory disorders in stroke patients. Researchers discovered a 12-fold increase in the birth of new cells in rodents after stroke, which may lead to rewireing the brain and helping survivors recover lost memory function.
A study reveals a dramatic rise in oral warts among HIV patients treated with protease inhibitors, which are effective against HIV. The researchers found that these warts were difficult to control and highly prone to recurrence, causing discomfort and affecting eating habits.
A team of researchers at Duke University Medical Center has mapped a region of human chromosome 11 and identified a new gene, RRM1, that is believed to be responsible for the aggressive nature of lung cancer. The gene's role in DNA production and repair makes it a potential therapeutic target for improving treatment outcomes.
Researchers identified HIV's key molecular site in the brain and colon as CCR5 co-receptor. This finding suggests a potential target for preventing virus entry into these tissues and possibly others.
A crucial molecular dance has been identified as the primary driver of pulmonary fibrosis, an incurable lung inflammation. Researchers discovered that a protein called integrin activates TGF Beta, leading to excessive fibrous scarring in lungs.
Researchers found two embryonic genes essential for fetal bone formation also play a crucial role in adult fracture repair. The study's findings shed light on the molecular mechanisms of bone healing and have the potential to develop targeted, injection-based therapies.
Researchers have successfully transplanted laboratory-grown neuronal cells into the brains of seven stroke patients, with some showing small improvements in motor skills and speech. The therapy, developed by scientists at the University of Pittsburgh Medical Center, aims to restore lost motor skills and has been deemed safe so far.
Researchers found that snakes use vision to locate places and rely on visual cues to escape a maze-like arena. Younger snakes are more adaptable, while older ones focus on visual cues.
