Testosterone therapy does not raise risk of aggressive prostate cancer Posted: 07 May 2016 11:33 AM PDT Men with low levels of the male sex hormone testosterone need not fear that testosterone replacement therapy will increase their risk of prostate cancer, suggests a new study.

Time to up the game: Video game designers need to do more for young disabled players Posted: 07 May 2016 06:12 AM PDT Computer games controlled through wheelchair movements have the potential to improve quality of life for young people with severe mobility impairments but more needs to be done to consider the needs and preferences of players in game design, new research shows.

Blood thinners on 'as needed' basis is safe and effective for lowering stroke risk as compared to long-term use Posted: 07 May 2016 06:12 AM PDT A new study shows the use of novel anticoagulants for AF prescribed on an 'as-needed basis' guided by diligent pulse monitoring, can be a safe and effective alternative to lowering overall risk of stroke.

PAD patients on statins may have lower amputation, early death risk Posted: 07 May 2016 06:12 AM PDT People with peripheral artery disease (PAD) who take cholesterol-lowering statins may have a lower risk of amputation and early death than PAD patients who don't take statins. The risk of amputation and early death among PAD patients on higher dose statins is lower for patients on low or moderate dose statins.

Scientists cite evidence that mosasaurs were warm-blooded Posted: 06 May 2016 01:04 PM PDT Mosasaurs – an extinct group of aquatic reptiles that thrived during the Late Cretaceous period – possibly were "endotherms," or warm-blooded creatures. Mosasurs were large aquatic reptiles that went extinct at the end of the Cretaceous period, about 66 million years ago.

Study of elite paralympic athletes supports benefits of exercise for children with cerebral palsy Posted: 06 May 2016 01:01 PM PDT For highly trained Paralympic athletes with cerebral palsy, bone mineral density and other measures of body composition are similar to those of able-bodied adults of similar age, reports a new study.

Scientists track Greenland's ice melt with seismic waves Posted: 06 May 2016 01:01 PM PDT Researchers have developed a new technique to monitor the seasonal changes in Greenland's ice sheet, using seismic vibrations generated by crashing ocean waves. The results may help scientists pinpoint regions of the ice sheet that are most vulnerable to melting. The technique may also set better constraints on how the world's ice sheets contribute to global sea-level changes.

'Hammerhead' creature was world's first plant-eating marine reptile Posted: 06 May 2016 01:01 PM PDT Newly-discovered fossils of the Triassic marine reptile Atopodentatus unicus have revealed that the animal had a bizarre hammerhead-shaped jaw apparatus. It used its strange jaw to feed on plants, making it the first herbivorous marine reptile.

Smartphones uncover how the world sleeps Posted: 06 May 2016 01:01 PM PDT A pioneering study of worldwide sleep patterns combines math modeling, mobile apps and big data to parse the roles society and biology each play in setting sleep schedules.

Scientist will use satellite data to study lightning that sizzles Posted: 06 May 2016 10:25 AM PDT Researchers want to learn more about long-stroke lightning that makes things sizzle.

Small and powerful: Pushing the boundaries of nano-magnets Posted: 06 May 2016 10:25 AM PDT Researchers built extremely small, thermally stable magnetic particles with magnetic properties comparable to some rare earth magnets, the strongest permanent magnets ever created. These tiny magnets are as small as 5 nanometers, a million times smaller than an ant.

Why 'sharks get cancer, mole rats don't' Posted: 06 May 2016 10:25 AM PDT A new book by a radiation oncologist explores how animals can help us understand how the immune system can be used to fight cancer.

Anticoagulation medications show no gender-based variations in outcomes for TAVR patients Posted: 06 May 2016 07:56 AM PDT A study on the impact of using different anticoagulation medications on men and women who have undergone a transcatheter aortic valve replacement (TAVR) found no difference in early vascular complications or mortality.

Catalytic nanocages: Hollow and filled with potential Posted: 06 May 2016 07:04 AM PDT Catalytic nanocages, which are tiny, open structures with reactive surfaces that could boost key chemical processes, are notoriously difficult to synthesize. Scientists recently succeeded in a new approach.

Breastfeeding is good for yet another reason, researchers discover Posted: 06 May 2016 06:58 AM PDT A mother's breast milk supports immune responses in her newborn that help the infant's gut become a healthy home to a mix of bacterial species, thanks in part to newly identified antibodies from the mother, according to a study.

Young women at greater risk for adverse outcomes following PCI Posted: 06 May 2016 06:57 AM PDT Women younger than 55 years of age who undergo percutaneous coronary intervention for acute coronary syndrome are more likely to experience one-year adverse cardiovascular events due to risk factors such as diabetes and chronic kidney disease, yet they are less likely to receive potent antiplatelet therapy than men.

Manipulation of specific neurons helps to erase bad memories, enhance good ones Posted: 05 May 2016 07:31 PM PDT A step has been taken toward the possibility of tuning the strength of memory by manipulating one of the brain's signaling memory mechanisms, a neurotransmitter called acetylcholine.

Online tool maps Louisiana's water flow interactions to preserve state's fresh water Posted: 05 May 2016 07:29 PM PDT As part of an effort to preserve Louisiana's fresh water resources, researchers have developed two online tools that offer a first-of-their-kind look at how Louisiana's waters interact with each other. These tools will help fishermen, oystermen, planners, decision makers, and all Louisianans understand the state's unique water flow patterns.
