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%. 

First proof of isolated attosecond pulse generation at the carbon K-edge

Posted: 20 Mar 2015 07:17 AM PDT

Researchers have been able to demonstrate, for the first time, the generation of isolated attosecond pulses at the water window. This achievement permits tracking and visualizing electronic motion with element specificity, i.e. bond formation and breaking during a chemical reaction, exciton dynamics in organic solar cells or the occurrence of ultrafast magnetism.

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.

Adapting to climate change will bring new environmental problems

Posted: 20 Mar 2015 06:13 AM PDT

Adapting to climate change could have profound environmental repercussions, according to a new study. Research reveals that adaptation measures have the potential to generate further pressures and threats for both local and global ecosystems. "Climate change is a just a little bit more complicated than we previously thought. We need to take into account not only the direct impact of climate change, but also how people will respond to such change - the impact of adaptation," notes the lead researcher.

Welding system of the future is self-learning

Posted: 20 Mar 2015 06:13 AM PDT

Scientists are developing an entirely new kind of welding system, one which solves quality and productivity problems related to automated and mechanized welding. The system is self-adjusting, flexible and adaptable, such that it can be integrated as part of different robotic systems and different manufacturers' power supplies.

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.
