A new blood test provides a fast and accurate tool to diagnose tuberculosis in children, a new proof-of-concept study shows. The newly developed test (TAM-TB assay) is the first reliable immunodiagnostic assay to detect active tuberculosis in children. The test features excellent specificity, a similar sensitivity as culture tests in combination with speed of a blood test. The promising findings are a major advance for the diagnosis of tuberculosis in children, particularly in tuberculosis-endemic regions.

A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by 2cm more than the global average of 6cm.
Researchers at the University of Southampton detected the rapid rise in sea-level by studying satellite scans of a region that spans more than a million square kilometres.
Long term results for the investigational monoclonal antibody alirocumab, show that in addition to significantly reducing cholesterol on top of regular statin therapy, it also reduced the incidence of cardiovascular events, researchers reported in a Hot Line session today at ESC Congress 2014.
The ODYSSEY LONG TERM trial of alirocumab is the largest Phase 3 study, with the longest follow-up data for a new class of drugs called proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors.
Barcelona, Spain – Sunday 31 August 2014: A new batteryless cardiac pacemaker based on an automatic wristwatch and powered by heart motion was presented at ESC Congress 2014 today by Adrian Zurbuchen from Switzerland. The prototype device does not require battery replacement.
Raloxifene is a U.S. Food and Drug Administration (FDA)-approved treatment for decreasing fracture risk in osteoporosis. While raloxifene is as effective at reducing fracture risk as other current treatments, this works only partially by suppressing bone loss. With the use of wide- and small-angle x-ray scattering (WAXS and SAXS, respectively), researchers carried out experiments at the U.S.
Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries in 2016.
To the careful observer, a person's face has long provided insight into what is going on beneath the surface. Now, with the assistance of a web camera and software algorithms, the face can also reveal whether or not an individual is experiencing atrial fibrillation, a treatable but potentially dangerous heart condition.
LOS ANGELES - August 28, 2014: This week, a team of researchers from the USC Viterbi School of Engineering will share results from a pilot study on the effects of using humanoid robots to help children with autism practice imitation behavior in order to encourage their autonomy. Findings from the study, entitled "Graded Cueing Feedback in Robot-Mediated Imitation Practice for Children with Autism Spectrum Disorders," will be presented at the 23rd IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN) conference in Edinburgh, Scotland, on Aug. 27.
A person's home is their castle, and they populate it with their own subjects: millions and millions of bacteria.
A study published today in Science provides a detailed analysis of the microbes that live in houses and apartments. The study was conducted by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago.
WEST LAFAYETTE, Ind. – A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries.
If you want to make a mark in the world of computer games you had better have a good English vocabulary. It has now also been scientifically proven that someone who is good at computer games has a larger English vocabulary. This is revealed by a study at the University of Gothenburg and Karlstad University, Sweden.
The study confirms what many parents and teachers already suspected: young people who play a lot of interactive English computer games gain an advantage in terms of their English vocabulary compared with those who do not play or only play a little.
Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), the Vienna Center for Quantum Science and Technology (VCQ), and the University of Vienna have developed a fundamentally new quantum imaging technique with strikingly counterintuitive features. For the first time, an image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never touches the imaged object.
WASHINGTON, August 28, 2014 — Works of art can take years to create and just seconds to deface. It happened to Mark Rothko's "Black on Maroon" while on display at the Tate Modern gallery in London in 2012. A vandal tagged the painting, landing him two years in jail. Restoration experts teamed up with Dow Chemical to create a cleanser that would get rid of the graffiti and leave the art intact. Learn all about it in this episode of Speaking of Chemistry.
OAK RIDGE, Tenn., Aug. 27, 2014 – Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at the Department of Energy's Oak Ridge National Laboratory.
By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led by Parans Paranthaman and Amit Naskar is developing a better anode for lithium-ion batteries. An anode is a negatively charged electrode used as a host for storing lithium during charging.
Being involved in a gang poses considerable health-related risks for adolescent African American girls, including more casual sex partners and substance abuse combined with less testing for HIV and less knowledge about preventing sexually transmitted diseases, according to a new study.
