Paralysed people could get movement back through thought-control
Brain implant could allow people to 'feel' the presence of infrared light and one day be used to move artificial limbsScientists have moved closer to allowing paralysed people to control artificial limbs with their thoughts following a breakthrough in technology that gave rats an extra sense.A brain implant that allows the animals to "feel" the presence of invisible infrared light could one day be used to provide paralysed people with feedback as they move artificial limbs with their thoughts, or it could even extend a person's normal range of senses.Miguel Nicolelis, a neurobiologist at Duke University in North Carolina w...

Brain-to-brain interface transmits information from one rat to another | Mo Costandi
Electronically-linked brains could facilitate rehabilitation and revolutionize computingIn Star Trek, the Borg is a menacing race of cybernetically-enhanced beings who conquer other races and assimilate them. They do not act as individuals, but rather as an interconnected group that makes decisions collectively. Assimilation involves integrating other life forms into the Collective, using brain implants that connect them to the "hive mind," such that their biology and technology can help the Borg to become the perfect race. This is a popular concept that can be found elsewhere in science fiction, but scientists have now mo...

If only a Scotsman had boldly gone… | Kevin McKenna
The UK Space Conference opens in Glasgow this week – where better to hold it with all these UFOs around?Like many Scots, I am proud of my country's role in Earth's understanding of outer space. When it first dawned on me as a child that the most important member of Captain James T Kirk's Starship Enterprise was Scottish, I was bursting with pride. Neither do you get to have names such as Neil Armstrong or John Glenn unless there is a significant quotient of Scots blood in you. And when it was revealed many years later that Obi-Wan Kenobi too was Scottish, well… our place in cosmology was finally secured. There have eve...

Music gives people a voice when words fail them at the end of their lives | Bob Heath
A music therapist describes how improvising songs can open a vital channel of communication in palliative careAll that was dear to me, down below the seaI cannot hold this piece of driftwoodWhen life abandons meLiz, a patient at the Sobell House hospice, 2013In palliative care, when clients and their therapists get to know one another they do so with a shared knowledge, whether voiced or not, that while both of them are going to die eventually, at least one of them is going to be doing it very soon.The relationship between client and therapist is always unique.

Do No Harm: Stories of Life, Death and Brain Surgery review
Patients see neurosurgeons as gods, but what is the reality? Henry Marsh has written a memoir of startling candourWe go to doctors for help and healing; we don't expect them to make us worse. Most people know the aphorism taught to medical students, attributed to the ancient Greek Hippocrates but timeless in its quiet sanity: "First, do no harm." But many medical treatments do cause harm: learning how to navigate the risks of drug therapies, as well as the catastrophic consequences of botched or inadvised surgical operations, is a big part of why training doctors takes so long. Even the simplest of therapies carries the ri...

MRI reveals genetic activity: Deciphering genes' roles in learning and memory
Doctors commonly use magnetic resonance imaging (MRI) to diagnose tumors, damage from stroke, and many other medical conditions. Neuroscientists also rely on it as a research tool for identifying parts of the brain that carry out different cognitive functions. Now, biological engineers are trying to adapt MRI to a much smaller scale, allowing researchers to visualize gene activity inside the brains of living animals.

Poor cardiovascular health linked to memory, learning deficits
People with poor cardiovascular health have a substantially higher incidence of cognitive impairment. Better cardiovascular health was more common in men and among people with higher education and higher income. The incidence of mental impairment was found more commonly in those with a lower income, who lived in the 'stroke belt' or had cardiovascular disease.

With the right rehabilitation, paralyzed rats learn to grip again
After a large stroke, motor skills barely improve, even with rehabilitation. An experiment conducted on rats demonstrates that a course of therapy combining the stimulation of nerve fiber growth with drugs and motor training can be successful. The key, however, is the correct sequence: Paralyzed animals only make an almost complete recovery if the training is delayed until after the growth promoting drugs have been administered.

Work Wellness Programs May Soon Include Genetic Testing
Your employer may one day help determine if your genes are why your jeans have become too snug.
Big companies are considering blending genetic testing with coaching on nutrition and exercise to help workers lose weight and improve their health before serious conditions like diabetes or heart disease develop. It's a step beyond the typical corporate wellness programs that many companies are using to make workers more aware of their risk factors and improve their health. Genetic testing in corporate wellness programs also is relatively uncharted territory. Many employers and insurers cover these tests and counseling for med...

John Glenn Says Evolution Should Be Taught In Schools
COLUMBUS, Ohio (AP) — John Glenn, who declared as a 77-year-old in a news conference from space that "to look out at this kind of creation out here and not believe in God is to me impossible," says facts about scientific discovery should be taught in schools — and that includes evolution.
The astronaut, now 93 with fading eyesight and hearing, told The Associated Press in a recent interview that he sees no contradiction between believing in God and believing in evolution.
"I don't see that I'm any less religious by the fact that I can appreciate the fact that science just records that we change with evolution and tim...

The 8 Most Important Things We've Learned About Happiness In The Past 10 Years
We're living in a golden age of happiness -- the scientific study of happiness, at least.
The field of positive psychology has exploded in growth since its inception in 1998, dramatically increasing our understanding of human flourishing. We now know more than ever about what makes us happy, how we can spread happiness socially and geographically, and how happiness affects our physical and mental health.
But it's just the beginning. In the next decade, we're likely to see not only a greater understanding of positive emotions, but also the application of this research on a practical level to improve well-being on a globa...

A Hidden Danger In The New Versions Of Birth Control Pills
Women who take a newer version of birth control pills have a doubled risk of developing potentially fatal blood clots, according to a new study published in the British medical journal BMJ.
Venous thromboembolism is a serious condition that encompasses both deep vein thrombosis -- when a person develops a blood clot in the legs -- and pulmonary embolism, in which the clot travels to the lungs and obstructs breathing. VTE is potentially fatal, and the study indicates that women who take combined oral contraceptives with newer progesterone formulations are two times more likely to develop it as opposed to women who take a ...

Why You Should Never, Ever Pull An All-Nighter
It's pretty straight forward: Sleep deprivation is really bad for you.
But even if you don't pull all-nighters, chronically getting too little sleep can be dangerous. For example, drowsiness behind the wheel can be just as deadly as driving under the influence. Over time, in serious cases, sleep deprivation can result in heart disease, stroke and diabetes. And in the immediate aftermath, going without sleep can lead to lack of focus and brain fog, stress and irritability.
But what happens after just one night of no sleep? Watch the Ted-Ed video above to learn about an experiment a high schoo...

In The Marshall Islands, Traditional Agriculture And Healthy Eating Are A Climate Change Strategy
LAURA VILLAGE, Marshall Islands -- Holding in his hand a bunch of what he called mountain apples, Steve Lepton grinned like a kid with a new toy. “Oh, it’s good,” he said. “Yesterday I didn’t find any fruit on this one. Wow, this is great. They’re getting red.” The delicate little fruit is crunchy like an apple and sweet. It’s a popular snack in the Marshall Islands, Lepton told The WorldPost, but kids pickle it with salt and Kool-Aid, which defeats the purpose of eating fruit in the first place. As the Global Climate and Health Alliance made clear with an announcement ...
