Attention Depends On Brain Regions Syncing Up; Unnecessary 'Cross-Talk' Could Explain Attention Deficits
In order to study attention deficits, researchers used electrodes implanted in the brains of epileptic patients to gauge in greater detail the synchrony of activity among different brain regions involved with attention.
Sitting Too Long Can Cause Early Death In Women: Not Even A Gym Membership Can Make Up For Ills Of Sedentary Lifestyle
Two studies link a sedentary lifestyle to chronic illnesses and higher mortality but also emphasize the health benefits of staying on your feet as much as possible.
Brain Activity Linked To Metabolism: Ancient Greeks Knew Fasting Reduces Epileptic Seizures, Now Doctors Know Why
A study looking at inhibitory neurons found a chemical connection between brain cells' metabolism and signaling, which explains how fasting can reduce epilepsy. Researchers found that breast cancer is particularly good at spreading to the brain because it is able to survive on the organ's most abundant neurotransmitter and seem like any other nerve cell. Social networks make it all too easy for people to poignantly compare themselves with others, which can result in one having the twisted belief that everyone else is doing better in life — something known as the "friendship paradox." Despite the childhood obesity "epidemic" slowing down, obesity still increasingly afflicts poorer kids who face more challenges in obtaining healthier diets and opportunities to exercise.
Men's Y Sex Chromosome Is Here To Stay Despite Being 'Puny'; Evolution Will Prevent Male Fertility Genes From Demise, Study Says
By comparing African and European males' Y sex chromosomes, researchers were able to deduce the continued importance of keeping this DNA around the grand scheme of evolution and natural selection.
Daily Use Of 'Skunk Type' Pot Hastens First Psychotic Episode; Study Links Pattern Of Cannabis Use To Mental Illness
Researchers found that patterns of cannabis use — frequency, strength, and age — affect when someone experiences their first psychotic episode. The nation's largest nurse organization found that despite the recent health care overhaul, for-profit hospitals rip you off by unceasingly increasing their costs to levels that are several times the actual cost of care.
Intestine From 1800s Cholera Victim Provides Clues About Deadly Pathogen; Preserved DNA Is A Window Into Historic Pandemics
Researchers analyzed old tissue preserved at a medical museum that contains DNA fragment of deadly cholera strains of long ago. The genetic traces are allowing them to forensically piece together the deadly nature of a pandemic that happened in the early 1800s.
Some Areas Of The Adult Brain Retain 'Childlike' Qualities; Youthful Gene Activity Keeps Our Minds Well Connected
Researchers found that parts of the adult brain displays genetic and metabolic activity that is akin to a young child's brain, indicating that new brain connections can rapidly be made during late adulthood to sustain the ability to learn and retain new information.
'Supersizing' Healthy Food May Entice Us To Eat Better: How The Allure Of Saving Money Makes Us Buy More Veggies
Our propensity to not be able to pass up a deal can be used to motivate better eating habits, researchers find.
