A UBC research team led by Prof. Chris Overall discovered a protein that reduces inflammation and halts the flow of white blood cells. The discovery, published in Science, may lead to new treatments for chronic inflammatory diseases such as arthritis and lung disease.
Researchers found high levels of ammonia in vehicle exhaust due to catalytic converter usage. Ammonia contributes to the formation of small airborne particles, a concern for human health.
Research by Dr. C. A. Tuggle found that many TV news directors and reporters believe high-tech 'toys' are being used to extend coverage beyond a story's real value. The study also shows that live reporting is becoming more common, but often ratings poorly with viewers.
Researchers at NYU Langone Health and the University of Pennsylvania School of Medicine have discovered that hair follicles are the source of new cells for the skin's outermost layer, the epidermis. These stem cells reside in a protected area called the bulge, which migrates to the epidermis, replenishing the skin throughout life.
A study by researchers found that Ben & Jerry's World's Best Vanilla Ice Cream contains almost 200 times the 'safe' daily dose of dioxin. The level of dioxin could cause up to 2,000 extra cancers among lifetime consumers.
Researchers discovered an enzyme called isocitrate lyase (ICL) that allows TB bacteria to persist in macrophages and evade immune attack. A drug targeting ICL may reduce treatment time for chronic infection. The enzyme's crystal structure has been determined, providing clues for designing drugs to attack persistent TB bacteria.
Researchers have developed an artificial nose that senses smell by visualizing color changes in metalloporphyrin dyes, offering improved sensitivity and humidity resistance compared to human noses. The technology has various applications in industries such as food and beverage, perfume, customs checkpoints, and chemical workplaces.
A new technique developed by UF researchers reduces toxic pollution from incinerating CCA-treated wood, making it less likely to leach into groundwater. The method introduces limestone to react with arsenic, forming larger particles that stay in the ash instead of escaping through smokestacks.
The median annual salary for chemists increased by 3% to $70,000, with industry paying the most. However, women chemists earn significantly lower salaries and have limited job opportunities.
A consortium of researchers found that isocitrate lyase (ICL) enables the tuberculosis bacterium to use fatty acids as energy. Disabling ICL crippled the bacterium in its persistent phase, suggesting a potential target for TB therapies. Current treatments are often ineffective due to the bug's ability to persist in the body.
Researchers found that the northern Hayward fault slips at a rate of 5-7 millimeters per year, similar to the surface, indicating it is not locked and releasing built-up strain. This reduces the threat of a major quake on this segment, but other hazards remain high.
Scientists at Georgia Institute of Technology have successfully created nanojets, tiny devices that could revolutionize electronics and gene delivery. The jets achieved a high velocity of up to 400 meters per second and formed droplets with remarkably uniform size.
A new study found that parents who value autonomy are less likely to respond harshly to sibling conflicts, leading to reduced fighting between teens. The amount of time spent together with teen children is also crucial in maintaining a warm sibling relationship.
Canadian researchers developed a method to steer proteins to bone, where they can accumulate and help build bone mass. Additional research is needed to determine the effectiveness of these proteins in growing bone tissue.
Scientists have successfully cloned a piglet using microinjection, marking a significant step towards xenotransplantation and genetically modified organs. The breakthrough could lead to human-friendly pig organs, reducing rejection rates and increasing the success of organ transplants.
The Consortium of New York Geriatric Education Centers has received a $1.3 million grant to provide interdisciplinary training on geriatric care. The grant will support 40-50 hour certificate programs, continuing education conferences, and outreach to underserved areas.
A study by University of Pennsylvania researchers found that the hair follicle and epidermis may originate from the same cache of cells. The finding suggests that daughter cells in the upper follicle migrate upward to form and maintain the new epidermis, and down to form the hair shaft.
Researchers have discovered a potent antioxidant in beer, specifically the compound xanthohumol found in hops, which has been shown to be six times more effective than antioxidants in citrus fruits and four times more effective than those in soy products. The study suggests that drinking beer may help prevent certain diseases such as h...
Hospital survival rates for Pneumocystis carinii pneumonia (PCP) patients have increased by 40% over the years 1992 to 1995, with a two-fold improvement in mechanical ventilation outcomes. New lung function data shows that Chinese children's lung capacity is lower than white youngsters', but also improved in certain tests.
