Good intentions ease pain, add to pleasure Posted: 18 Jan 2012 01:51 PM PST A nurse's tender loving care really does ease the pain of a medical procedure, and grandma's cookies really do taste better, if we perceive them to be made with love -- suggests newly published research. The findings have many real-world applications, including in medicine, relationships, parenting and business.

Saving dogs with spinal cord injuries Posted: 18 Jan 2012 12:53 PM PST Dogs with spinal cord injuries may soon benefit from an experimental drug currently being tested by researchers — work that they hope will one day help people with similar injuries.

Study maps destructive path from cigarette to emphysema Posted: 18 Jan 2012 11:36 AM PST Scientists described the track the toxic smoke takes through the tissues and how they accomplish their destructive work.

Solving the mystery of an old diabetes drug that may reduce cancer risk Posted: 18 Jan 2012 10:23 AM PST Researchers now report on how the diabetes drug metformin potentially reduces cancer risk.

Important gene-regulation proteins pinpointed by new method Posted: 18 Jan 2012 10:23 AM PST A novel technique precisely pinpoints the location of proteins that read and regulate chromosomes. The order of these proteins determines whether a brain cell, a liver cell, or a cancer cell is formed. Until now, it has been exceedingly difficult to determine exactly where such proteins bind to the chromosome, and therefore how they work. The new technique has the potential to take high-resolution snapshots of proteins as they regulate or miss-regulate an entire genome.

Breast cancer cells targeted, then burned, by gold-filled silicon wafers Posted: 18 Jan 2012 09:28 AM PST By shining infrared light on specially designed, gold-filled silicon wafers, scientists have successfully targeted and burned breast cancer cells. If the technology is shown to work in human clinical trials, it could provide patients a non-invasive alternative to surgical ablation, and could be used in conjunction with traditional cancer treatments, such as chemotherapy, to make those treatments more effective.

First link between potentially toxic PFCs in office air and in office workers' blood Posted: 18 Jan 2012 08:20 AM PST In a first-of-its-kind study, scientists are reporting that the indoor air in offices is an important source of worker exposure to potentially toxic substances released by carpeting, furniture, paint and other items. Their report documents a link between levels of these so-called polyfluorinated compounds in office air and in the blood of workers.

Contact lenses provide extended pain relief to laser eye surgery patients Posted: 18 Jan 2012 08:20 AM PST Scientists are reporting development of contact lenses that could provide a continuous supply of anesthetic medication to the eyes of patients who undergo laser eye surgery -- an advance that could relieve patients of the burden of repeatedly placing drops of medicine into their eyes every few hours for several days.

Lack of sleep makes your brain hungry Posted: 18 Jan 2012 08:17 AM PST New research shows that a specific brain region that contributes to a person's appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep. Poor sleep habits can therefore affect people's risk of becoming overweight in the long run.

Ulcer-causing bacteria baffled by mucus: Researchers discover impact of viscoelasticity on collective behavior of swimming microorganisms Posted: 18 Jan 2012 08:17 AM PST A new study demonstrates how introducing certain polymers—like those found in human mucus and saliva—into an aquatic environment makes it significantly more difficult for ulcer-causing bacteria and other microorganisms to coordinate.

Enhancing cognition in older adults also changes personality Posted: 18 Jan 2012 07:15 AM PST A program designed to boost cognition in older adults also increased their openness to new experiences, researchers report, demonstrating for the first time that a non-drug intervention in older adults can change a personality trait once thought to be fixed throughout the lifespan.

Does marriage really make people happier? Study finds few well-being advantages to marriage over cohabitation Posted: 18 Jan 2012 07:13 AM PST Married couples experience few advantages for psychological well-being, health, or social ties compared to unmarried couples who live together, according to a new study. While both marriage and cohabitation provide benefits over being single, these reduce over time following a honeymoon period.

Scientists create novel RNA repair technology Posted: 17 Jan 2012 04:15 PM PST Scientists have identified a compound that can help repair a specific type of defect in RNA, a type of genetic material. The methods in the new study could accelerate the development of therapeutics to treat a variety of incurable diseases such as Huntington's disease, Spinocerebellar ataxia, and Kennedy disease.

Polar growth at the bacterial scale reveals potential new targets for antibiotic therapy Posted: 17 Jan 2012 04:14 PM PST Microbiologists have identified a new bacterial growth process -- one that occurs at a single end or pole of the cell instead of uniform, dispersed growth along the long axis of the cell -- that could have implications in the development of new antibacterial strategies.

Mechanism by which newly approved melanoma drug accelerates secondary skin cancers uncovered Posted: 17 Jan 2012 04:14 PM PST Patients with metastatic melanoma taking the recently approved drug vemurafenib (Zelboraf®) responded well to the twice daily pill, but some of them developed a different, secondary skin cancer. Now, researchers have elucidated the mechanism by which vemurafenib excels at fighting melanoma but also allows for the development of skin squamous cell carcinomas.

New gene discovery unlocks mystery to epilepsy in infants Posted: 17 Jan 2012 11:54 AM PST Researchers have come a step closer to unlocking a mystery that causes epileptic seizures in babies. Benign familial infantile epilepsy has been recognized for some time as infantile seizures, without fever, that run in families but the cause has so far eluded researchers. However, clinical researchers have now discovered a gene.

Anti-malaria drug synthesized with the help of oxygen and light Posted: 17 Jan 2012 11:37 AM PST In the future it should be possible to produce the best anti-malaria drug, artemisinin, more economically and in sufficient volumes for all patients.

Novel way to prevent drug-induced liver injury Posted: 15 Jan 2012 11:00 AM PST Investigators have developed a novel strategy to protect the liver from drug-induced injury and improve associated drug safety. The team reports that inhibiting a type of cell-to-cell communication can protect against damage caused by liver-toxic drugs such as acetaminophen.

Chemists devise chemical reaction that holds promise for new drug development Posted: 12 Jan 2012 06:58 AM PST Scientists have devised a new method for making complex molecules. The reaction they have come up with should enable chemists to synthesize new varieties of a whole subclass of organic compounds called nitrogen-containing heterocycles, thus opening up new avenues for the development of novel pharmaceuticals and natural products ranging from chemotherapeutic compounds to bioactive plant materials such as morphine.
