Smokers at twice risk of prostate cancer recurring after surgery Posted: 20 Mar 2015 07:10 PM PDT Current smokers, and those who have quit smoking less than 10 years previously, have twice the risk of a recurrence of prostate cancer after surgery, according to new research.

Changes in surgery methods significantly reduces antibiotic resistance Posted: 20 Mar 2015 07:10 PM PDT A new study shows how changing working methods in surgery can significantly reduce bacterial resistance to antibiotics, while maintaining protection against infection and reducing costs by up to 60%.

Bright new hope for beating deadly hereditary stomach, breast cancers Posted: 20 Mar 2015 06:15 AM PDT Deadly familial stomach and lobular breast cancers could be successfully treated at their earliest stages, or even prevented, by existing drugs that have been newly identified by cancer genetics researchers.

'Attract and kill:' Trapping malaria mosquito moms before they lay eggs Posted: 20 Mar 2015 06:15 AM PDT In a world first, researchers have found that a naturally occurring chemical attracts pregnant malaria-transmitting mosquitoes -- a discovery which could boost malaria control efforts. The chemical, cedrol, found in mosquito breeding sites near Africa's Lake Victoria, could be used in traps that would 'attract and kill' the female mosquito, preventing reproduction before she lays hundreds of eggs.

Government anti-drinking messages irrelevant to young binge drinkers, study finds Posted: 20 Mar 2015 06:14 AM PDT Government advertising campaigns to tackle excessive drinking are dismissed as irrelevant by young binge drinkers, because consuming extreme quantities of alcohol is part of their sub-cultural social identity, according to new research.

Life-saving treatments learned from war being missed Posted: 19 Mar 2015 06:30 PM PDT Trauma is responsible for more global deaths annually than HIV, malaria and tuberculosis combined. Yet healthcare systems in many countries are missing out on life-saving treatments learned on the battlefield, according to a new review.

Mechanobiology provides insight into disease and healing processes Posted: 19 Mar 2015 04:31 PM PDT Researchers are gaining further insight into how the mechanical environment of cells drives fundamental cellular processes such as motility, growth and survival. These processes are integral to many clinical challenges, from cancer prognosis to wound healing and skin repair.

South-East Asian haze increases risk of respiratory mortality Posted: 19 Mar 2015 04:31 PM PDT Research has shown a significant association between haze events in South-East Asia and mortality rates caused by respiratory illness on the west coast of peninsular Malaysia.

Excellent Outcomes Among HIV+ Kidney Transplant Recipients Posted: 19 Mar 2015 04:30 PM PDT Compared with uninfected (HIV-/HCV-) kidney transplant recipients, mono-infected HIV+ (HIV+/HCV-) recipients had similar 5-year and 10-year kidney survival rates, while HIV+ recipients co-infected with HCV (HIV+/HCV+) had worse kidney survival rates. Patient survival among mono-infected HIV+ recipients was similar to uninfected recipients but was significantly lower for co-infected recipients.

Fewer multiple births could reduce autism risk in ART children Posted: 19 Mar 2015 01:55 PM PDT The incidence of diagnosed autism was twice as high for assisted reproductive technology (ART) as non-ART births among the nearly 6 million children in a recent study, born in California from 1997 through 2007. However, much of the association between ART and autism was explained by age and education of the mother as well as adverse perinatal outcomes, especially multiple births.

Scientists trace genomic evolution of high-risk leukemia Posted: 19 Mar 2015 01:53 PM PDT By genomic sequencing of leukemia cells from relapsed patients at different stages, scientists have discovered key details of how acute lymphoblastic leukemia (ALL) cells mutate to survive chemotherapy.

Two Distinct Populations of CD4 T Cells Play Different Roles in Immune System Posted: 19 Mar 2015 01:53 PM PDT Utilizing a novel transgenic mouse model, scientists have found that CD4 T cells divide into two different populations that each has a different job.

Being near greened vacant lots lowers heart rates Posted: 19 Mar 2015 01:53 PM PDT Greening vacant lots may be associated with biologic reductions in stress, according to a new study. Residents who walked near newly greened vacant lots had significantly lower heart rates compared to walking near a blighted, or neglected, vacant lot.

Acne spot treatment: Latest in nanotechnology, transdermal drug delivery to take on an old problem Posted: 19 Mar 2015 11:34 AM PDT Acne, a scourge of adolescence, may be about to meet its ultra high-tech match. By using a combination of ultrasound, gold-covered particles and lasers, researchers have developed a targeted therapy that could potentially lessen the frequency and intensity of breakouts, relieving acne sufferers the discomfort and stress of dealing with severe and recurring pimples.

Even at a molecular level, taking it slow helps us cope with stress Posted: 19 Mar 2015 11:33 AM PDT A new molecular pathway critical to aging has been discovered by scientists. They found that by slowing down the activity of mitochondria in the blood stem cells of mice, they could enhance the cells' capacity to handle stress and rejuvenate old blood.

New genetic method promises to advance gene research, control insect pests Posted: 19 Mar 2015 11:33 AM PDT A new method for generating mutations in both copies of a gene in a single generation has been developed by biologists. This method could rapidly accelerate genetic research on diverse species and provide scientists with a powerful new tool to control insect borne diseases such as malaria as well as animal and plant pests.

Vitamin D helps immune cells prevent atherosclerosis, diabetes Posted: 19 Mar 2015 09:40 AM PDT Altered signaling through the vitamin D receptor on certain immune cells may play a role in causing the chronic inflammation that leads to cardiometabolic disease, the combination of type 2 diabetes and heart disease that is the most common cause of illness and death in Western populations.

Kidney cancer detected early with urine test Posted: 19 Mar 2015 08:27 AM PDT If kidney cancer is diagnosed early -- before it spreads beyond the kidney -- 80 percent of patients survive. However, finding it early has been among the disease's greatest challenges. Now, researchers have developed a noninvasive method to screen for kidney cancer that involves measuring the presence of proteins in the urine.
