Deadly bug strikes in a day

A deadly bacteria that can be picked up by a simple sniff can travel to the brain and spinal cord in just 24 hours, a new Griffith University and Bond University study has found.

The pathogenic bacteria Burkholderia pseudomallei, which causes the potentially fatal disease melioidosis, kills 89,000 people around the world each year and is prevalent in northern Australia and southeast Asia.

Previously, researchers did not understand how the bacteria travelled to the brain and spinal cord, or just how quickly.

We have all bumped our heads at some point, and such incidents are usually harmless. This is thanks to fluid-filled chambers in our brain that offset minor knocks and jolts and provide padding for sensitive components of our nervous system. Cerebral fluid, however, has more than just a protective function: It removes cellular waste, supplies our nervous tissue with nutrients, and transports important messenger substances. How these messenger substances are actually being delivered to their destination in the brain, however, was unclear until now.

Why Clinton and Trump backers don't mix

Why Clinton and Trump backers don't mix

EAST LANSING, Mich. -- Living around people with opposing political viewpoints affects your ability to form close relationships and accept other perspectives - and may even change your personality, finds a national study led by a Michigan State University scholar.

The findings also could help explain why so many Americans are moving to areas that suit them politically, further segregating the nation into "red" and "blue" states, said William Chopik, MSU assistant professor of psychology.

Scripps Florida scientists link bipolar disorder to unexpected brain region

JUPITER, FL - July 8, 2016 - While bipolar disorder is one of the most-studied neurological disorders--the Greeks noticed symptoms of the disease as early as the first century--it's possible that scientists have overlooked an important part of the brain for its source.

Like humans, lowly cockroach uses a GPS to get around, scientists find

Like humans, lowly cockroach uses a GPS to get around, scientists find

Rats, men and cockroaches appear to have a similar GPS in their heads that allows them to navigate new surroundings, researchers at Case Western Reserve University report.

The finding, published in journal Current Biology, is likely an example of convergent evolution--that is, distinct animals developed similar systems to manage the same problems.

A recipe for friendship: Similar food

How do you build rapport with a new employer or someone on a first date? It turns out that there may be a simple strategy that's often overlooked: eat the same food as your companion.

Researchers from the University of Chicago launched a series of experiments to determine whether similar food consumption facilitates a sense of closeness and trust between adults, and their results were recently published online in the Journal of Consumer Psychology.

When red evokes mischief

The color red is usually associated with inducing compliant behavior with stop signs, warning lights and corrections on a graded assignment.

What if this color did just the opposite in certain situations? Results from a new study published online in the Journal of Consumer Psychology suggest that certain personality types are more likely to rebel against the norm--rather than comply--when seeing the color red.

Faking to finish -- women feign sexual pleasure to end 'bad' sex

When talking about troubling sexual encounters some women mention faking sexual pleasure to speed up their male partner's orgasm and ultimately end sex.

This is one of the findings of a qualitative study by Emily Thomas (Ryerson University, Canada) Monika Stelzl, Michelle Lafrance (St. Thomas University, Canada) that will be presented today, Friday 8 July 2016, at the British Psychological Society's Psychology of Women annual conference in Windsor.

Neuroscientists warn against self-administered brain stimulation

Noninvasive electrical brain stimulation offers hope as a potential new tool to ease the symptoms of certain diseases and mental illnesses, but neuroscientists in the July 7 issue of Annals of Neurology are warning against self-administered brain stimulation by so-called "do-it-yourself" (DIY) users.

New study finds no evidence of weekend increase in mental health patient suicide

A new study from The University of Manchester, prompted by current government policy for a 'seven-day NHS', has found that suicide deaths by mental health patients are actually lower at the weekends.

A current government policy priority is to extend health services to a full 'seven-day NHS', partly due to claims that patients admitted at the weekend are more likely to die because of lack of specialist staffing and services.
