Largest study of CTE finds it in 6% of subjects

Thursday June 20th, 2019 07:35:48 PM
Nearly 6% of athletes and non-athletes were found to have the neurodegenerative disorder chronic traumatic encephalopathy (CTE) in the largest, and broadest, study conducted of the disease to date. Kevin F. Bieniek, Ph.D., of UT Health San Antonio is the lead author.

Not always reaching your potential is okay, but overthinking it is a problem

Thursday June 20th, 2019 07:35:24 PM
Having aspirations helps us navigate life in a meaningful and fulfilling way, but it can also cause psychological distress when hopes are left unfulfilled. New research has found that it's not failing to make progress toward our 'ideal-self' that is problematic but rather the tendency to focus on that lack of progress in a negative way that leads to psychological distress.

Treatment for common cause of diarrhea more promising

Thursday June 20th, 2019 07:35:13 PM
Researchers have figured out how to grow the intestinal parasite Cryptosporidium in the lab, an achievement that will speed efforts to treat or prevent diarrhea caused by the parasite.

Scientists discover new method for developing tracers used for medical imaging

Thursday June 20th, 2019 07:35:05 PM
Researchers discovered a method for creating radioactive tracers to better track pharmaceuticals in the body as well as image diseases, such as cancer, and other medical conditions.

Engineers 3D print flexible mesh for ankle and knee braces

Thursday June 20th, 2019 07:35:00 PM
Engineers have designed pliable, 3D-printed mesh materials whose flexibility and toughness they can tune to emulate and support softer tissues such as muscles and tendons. They can tailor the intricate structures in each mesh, and they envision the tough yet stretchy fabric-like material being used as personalized, wearable supports, including ankle or knee braces, and even implantable devices, such as hernia meshes, that better match to a person's body.

Animals may have more than one means of surviving hypoxia

Thursday June 20th, 2019 07:34:56 PM
A tidepool crustacean's ability to survive oxygen deprivation though it lacks a key set of genes raises the possibility that animals might have more ways of dealing with hypoxic environments than had been thought.

Looking for freshwater in all the snowy places

Thursday June 20th, 2019 07:34:50 PM
Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world.

Medical proof a vacation is good for your heart

Thursday June 20th, 2019 07:34:43 PM
New research shows that using, instead of losing, your vacation time can be beneficial to your heart health.

Spotting objects amid clutter

Thursday June 20th, 2019 04:14:44 PM
A new technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned 'Magic Eye' image if they observe it in just the right way.

Spiders risk everything for love

Thursday June 20th, 2019 04:14:31 PM
A biology study finds that blue jays can easily spot wolf spiders engaged in their courtship rituals. The results demonstrate the powerful influence of sexual selection.

Biomedical bleeding may impact horseshoe crabs' spawning behavior and movement

Thursday June 20th, 2019 04:14:21 PM
Horseshoe crabs that have undergone biomedical bleeding tend to reside in deeper water and approach mating beaches less often, according to a new study.

Artificial intelligence identifies 'kissing bugs' that spread Chagas disease

Thursday June 20th, 2019 04:14:18 PM
A researcher published proof-of-concept research showing artificial intelligence can recognize 12 Mexican and 39 Brazilian species of kissing bugs with high accuracy by analyzing ordinary photos -- an advantage for officials looking to cut the spread of Chagas disease.

Vanilla makes milk beverages seem sweeter

Thursday June 20th, 2019 04:14:10 PM
Adding vanilla to sweetened milk makes consumers think the beverage is sweeter, allowing the amount of added sugar to be reduced, according to new researchers, who will use the concept to develop a reduced-sugar chocolate milk for the National School Lunch Program.

Perovskite solar cells tested for real-world performance -- in the lab

Thursday June 20th, 2019 04:14:08 PM
Researchers bring diurnal and seasonal variations into the lab to test the performance of perovskite solar cells under realistic conditions.

Pigs help scientists understand human brain

Thursday June 20th, 2019 04:14:06 PM
For the first time, researchers have used an imaging method normally reserved for humans to analyze brain activity in live agricultural swine models, and they have discovered that pig brains are even better platforms than previously thought for the study of human neurological conditions such as Alzheimer's and Parkinson's.

Timed release of turmeric stops cancer cell growth

Thursday June 20th, 2019 04:14:04 PM
A new research team has developed a drug delivery system using curcumin, the main ingredient in the spice turmeric, that successfully inhibits bone cancer cells while promoting growth of healthy bone cells.

Dynamic collaboration behind new research into best way of using biologging tags

Thursday June 20th, 2019 04:14:01 PM
Methods used to design F1 cars and spacecraft have played a crucial role in new research into the tags used to track animal movements. Ecologists teamed up with aerospace colleagues to find the best way to reduce the drag of biologging tags -- the recording devices used to track animal movements and behavior.

Heat kills invasive jumping worm cocoons, could help limit spread

Thursday June 20th, 2019 04:13:57 PM
New research shows that temperatures of about 100 degrees Fahrenheit kill the cocoons of invasive jumping worms. That's good news for ecologists and horticulturalists who are working to slow or stop the spread of the worms, which can damage the soils they invade.

Landmark study signals shift in thinking about stem cell differentiation

Thursday June 20th, 2019 04:13:54 PM
Researchers found that embryonic stem cells commit to a cell fate far more rapidly than anticipated.

Laser method promising for detecting trace chemicals in air

Thursday June 20th, 2019 02:49:11 PM
Researchers have developed a new laser-based method that can detect electric charges and chemicals of interest with unprecedented sensitivity. The new approach could one day offer a way to scan large areas for radioactive material or hazardous chemicals for safety and security applications.
