Electric buses with wireless charging set for UK runs in Milton Keynes
(Phys.org) —The UK can celebrate the launch of its first electric bus routes, to swing into operation this month in Milton Keynes, where eight electric buses will be running, taking over a busy "Number 7" 15-mile route, and covering two suburbs of Wolverton and Bletchley. These buses are the first of their kind in the UK. The new timetable will be implemented later this month. The electric bus fleet is operating as a five-year, multi-partner trial program. Among the participants are the European division of Japanese company Mitsui and design engineering consultancy Arup According to Arup, the data collected in the Milton Keynes trial could be used to kick-start electric bus projects in other towns and cities worldwide
3-D printing set to break out of niche
Some of the oddest items on display this week at the International CES gadget show were edible, origami-like sculptures made of sugar, their shapes so convoluted as to baffle the eye.
Audi shows TLA solution to make those green lights (w/ Video)
(Phys.org) —The CES show in Las Vegas from January 7 to 10 provided a generous share of driver assistance technologies, where spectators were told how they can expect to interact with their cars as never before. One attention-grabber in the recent CES reports is something from German auto makers Audi called Traffic Light Assist (TLA). What if you were told your car had the ability to help you hit every green light on your journey? That could put a smile on any driver's face, and at CE testers from media sites earlier this week got to test Audi's TLA up and down the Las Vegas strip. Reports by the testers were favorable, inviting such words as "intriguing" and "slick." Simply put, Audi is shooting for a time when a driver gets in the car, starts driving, and, with the car's analysis of traffic light data, the driver will be able to know when the next light will change..

Complementary medicine in wide use to treat children with autism, developmental delay
In a study of the range of treatments being employed for young children with autism and other developmental delays, UC Davis MIND Institute researchers have found that families often use complementary and alternative medicine (CAM) treatments and that the most frequent users of both conventional and complementary approaches are those with higher levels of parental education and income.
Americans are living longer, but not as long as other countries
The good news is Americans are living longer. The bad is that we're not living as long as people in other countries.
Text messaging boosts flu vaccine rates in pregnant women
A study by researchers at the Mailman School of Public Health evaluated the impact of text messaging reminders for influenza vaccine in a low-income obstetric population. The findings showed that sending text messages to this population of women resulted in an uptick in influenza vaccination, especially for those who received the messages early in their third trimester. Results from the paper, "Influenza Vaccine Text Message Reminders for Urban, Low-Income Pregnant Women: A Randomized Controlled Trial," were published in the American Journal of Public Health, a special issue on the latest methods and practices in improving birth outcomes.

Non-coding DNA implicated in type 2 diabetes
Variations in non-coding sections of the genome might be important contributors to type 2 diabetes risk, according to a new study.
Tweaking MRI to track creatine may spot heart problems earlier, study suggests
A new MRI method to map creatine at higher resolutions in the heart may help clinicians and scientists find abnormalities and disorders earlier than traditional diagnostic methods, researchers at the Perelman School of Medicine at the University of Pennsylvania suggest in a new study published online today in Nature Medicine. The preclinical findings show an advantage over less sensitive tests and point to a safer and more cost-effective approach than those with radioactive or contrasting agents.
Study identifies population of stem-like cells where HIV persists in spite of treatment
Although antiviral therapy against HIV suppresses viral replication and allows infected individuals to live relatively healthy lives for many years, the virus persists in the body, and replication resumes if treatment is interrupted. Now investigators from Massachusetts General Hospital (MGH) and the Ragon Institute of MGH, MIT and Harvard may have found where the virus hides - in a small group of recently identified T cells with stem-cell-like properties.
Research uncovers key difference between our bodies' fight against viruses and bacteria
Scientists at The University of Nottingham have discovered a key difference in the biological mechanisms by which the immune system responds to viral and bacterial pathogens.
Study finds targetable mutation in rare brain tumor
A team led by investigators from Massachusetts General Hospital (MGH), Brigham and Women's Hospital (BWH) and the Broad Institute has found that a gene mutation associated with several types of cancer also may be responsible for a rare but debilitating brain tumor called papillary craniopharyngioma. Their discovery, reported online in Nature Genetics, could lead to new therapies for this currently hard-to-treat tumor.
Ultrasound directed to the human brain can boost sensory performance
Whales, bats, and even praying mantises use ultrasound as a sensory guidance system—and now a new study has found that ultrasound can modulate brain activity to heighten sensory perception in humans.
It's all coming back to me now: Researchers find caffeine enhances memory
For some, it's the tradition of steeping tealeaves to brew the perfect cup of tea. For others, it's the morning shuffle to a coffee maker for a hot jolt of java. Then there are those who like their wake up with the kind of snap and a fizz usually found in a carbonated beverage.
Scientists solve 40-year mystery of how sodium controls opioid brain signaling
Scientists have discovered how the element sodium influences the signaling of a major class of brain cell receptors, known as opioid receptors. The discovery, from The Scripps Research Institute (TSRI) and the University of North Carolina (UNC), suggests new therapeutic approaches to a host of brain-related medical conditions.

Designer 'swiss-army-knife' molecule captures RNA in single cells in their natural tissue environment
A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connections influence individual cell function and overall protein production.
