Can fish skin help treat burns? Malaria: Kenya, Ghana and Malawi get first vaccine. Image copyright D Poland/PATH The world's first vaccine against malaria will be introduced in three countries - Ghana, Kenya and Malawi - starting in 2018.
The RTS,S vaccine trains the immune system to attack the malaria parasite, which is spread by mosquito bites. The World Health Organization (WHO) said the jab had the potential to save tens of thousands of lives. In young bilingual children 2 languages develop simultaneously but independently. A new study of Spanish-English bilingual children by researchers at Florida Atlantic University published in the journal Developmental Science finds that when children learn two languages from birth each language proceeds on its own independent course, at a rate that reflects the quality of the children's exposure to each language.
In addition, the study finds that Spanish skills become vulnerable as children's English skills develop, but English is not vulnerable to being taken over by Spanish. In their longitudinal data, the researchers found evidence that as the children developed stronger skills in English, their rates of Spanish growth declined. Spanish skills did not cause English growth to slow, so it's not a matter of necessary trade-offs between two languages. Self-taught artificial intelligence beats doctors at predicting heart attacks. Doctors have lots of tools for predicting a patient’s health.
But—as even they will tell you—they’re no match for the complexity of the human body. Heart attacks in particular are hard to anticipate. Now, scientists have shown that computers capable of teaching themselves can perform even better than standard medical guidelines, significantly increasing prediction rates. How to super-size your memory, according to science.

Scans reveal that while memory champions' brains are nothing special in terms of anatomy, they do show changes in brain connectivity. What's more, neuroscientists were able to train people with ordinary memory skills to emulate the masters. The learners could remember lists of names at a time and showed similar brain connectivity patterns. Surprising Reason More Sex May Be Key To Happiness: Cuddling And Affection Increase Couples' Wellbeing. Researchers have long known that people who have more sex are generally happier than the those who get lucky less often, but the chicken and egg question remained: Does sex actually make you happier, or do happier people just have more sex?
According to a new study, sex really does make you happier, but it was the time spent cuddling after sex, and not the joy of orgasm, that made people happy. The study, now published online in Personality and Social Psychology Bulletin, revealed that it's general exchanges of words and signs of affection following sex that directly cause increased long-term happiness and more life satisfaction in couples who have sex at least once a week. Read: Make It Count: Sex Once A Week Makes For A Happy Life (Unless You're Single) “When engaging in sex, people not only seek an intimate connection, but indeed experience more affection, both when having sex and in the next several hours,”explained the researchers, The British Psychological Society reported.

In what is believed to be the first procedure of its kind in the world, doctors in Canada have saved a young mother’s life by resorting to a radical solution – they removed her lungs for six days while she waited for a transplant.
In April, Melissa Benoit arrived at a Toronto hospital with a severe lung infection. Doctors soon realised that Benoit, who had been born with cystic fibrosis, had just hours to live, leading them to consider the unprecedented approach. “It was a difficult discussion because when we’re talking about something that had never to our knowledge been done before, there were a lot of unknowns,” Dr Niall Ferguson of the University Health Network, the health authority responsible for the Toronto general hospital, told a news conference on Wednesday. Autism Researchers Discover Genetic ‘Rosetta Stone’ Distinct sets of genetic defects in a single neuronal protein can lead either to infantile epilepsy or to autism spectrum disorders (ASDs), depending on whether the respective mutations boost the protein’s function or sabotage it, according to a new study by UC San Francisco researchers.
Tracing how these particular genetic defects lead to more general changes in brain function could unlock fundamental mysteries about how events early in brain development lead to autism, the authors say. Blood-repellent materials: A new approach to medical implants. Medical implants like stents, catheters and tubing introduce risk for blood clotting and infection – a perpetual problem for many patients.
Colorado State University engineers offer a potential solution: A specially grown, “superhemophobic” titanium surface that’s extremely repellent to blood. The material could form the basis for surgical implants with lower risk of rejection by the body. Biomedical, materials approaches. End of fillings in sight as scientists find Alzheimer's drug makes teeth grow back Study finds association between eating hot peppers and decreased mortality. Like spicy food?
If so, you might live longer, say researchers at the Larner College of Medicine at the University of Vermont, who found that consumption of hot red chili peppers is associated with a 13 percent reduction in total mortality - primarily in deaths due to heart disease or stroke—in a large prospective study. The study was published recently in PLoS ONE. Going back for centuries, peppers and spices have been thought to be beneficial in the treatment of diseases, but only one other study—conducted in China and published in 2015 - has previously examined chili pepper consumption and its association with mortality.
This new study corroborates the earlier study's findings. There are some possible explanations for red chili peppers' health benefits, state Chopan and Littenberg in the study.

Despite years of evolution honing its capability to carry out the complicated mechanisms needed to ensure our survival, the body has not refined the process of healing skin. Sure, wounds inflicted on the body’s largest organ can heal, but we are left with scar tissue.
Scientists discover concussion biomarker - Northwestern Now. EVANSTON - The secret to reliably diagnosing concussions lies in the brain’s ability to process sound, according to a new study by researchers from Northwestern University’s Auditory Neuroscience Laboratory. Widely considered a crisis in professional sports and youth athletic programs, sports-related concussions have had devastating neurological, physical, social and emotional consequences for millions of athletes. Still, no single test has been developed to reliably and objectively diagnose concussions. The groundbreaking research, to be published Dec. 22 in the journal Nature, Scientific Reports, has found a biological marker in the auditory system that could take the ambiguity and controversy out of diagnosing concussions and tracking recovery.
“This biomarker could take the guesswork out of concussion diagnosis and management,” said lead author Nina Kraus, the Hugh Knowles Professor in the School of Communication and director of the Auditory Neuroscience Laboratory. Dr. Study: Toddlers of Obese Parents More Susceptible to Developmental Delays. Children born to obese parents are at increased risk of failing motor development and cognitive tests, according to an NIH-led study. Overweight parents could be at risk of having children with impaired development, according to a study published January 3 in Pediatrics. Researchers found that children whose parents were substantially overweight were more likely to fail developmental tests for fine motor skills, social competence, or cognitive problem-solving. The study is also one of the first to examine the effects of not just maternal weight, but paternal weight, on child development. Gene Therapy To Prevent Inherited Diseases May Cause Other Ills.

Why the #$%! Do We Swear? For Pain Relief. Bad language could be good for you, a new study shows. For the first time, psychologists have found that swearing may serve an important function in relieving pain. The study, published today in the journal NeuroReport, measured how long college students could keep their hands immersed in cold water. During the chilly exercise, they could repeat an expletive of their choice or chant a neutral word.
When swearing, the 67 student volunteers reported less pain and on average endured about 40 seconds longer. Although cursing is notoriously decried in the public debate, researchers are now beginning to question the idea that the phenomenon is all bad. How swearing achieves its physical effects is unclear, but the researchers speculate that brain circuitry linked to emotion is involved. Junk food cravings are triggered by the mere thought of being low class. It’s well established that people with low economic status are the hardest hit by the current obesity pandemic, as well as related health problems such as diabetes. A possible explanation for why people find it hard to maintain eye contact when talking. Prostate cancer laser treatment 'truly transformative' Surgeons have described a new treatment for early stage prostate cancer as "truly transformative". The approach, tested across Europe, uses lasers and a drug made from deep sea bacteria to eliminate tumours, but without causing severe side effects.
