The disposable test will revolutionise the way in which HIV tests are conducted around the world specifically in remote areas where availability of equipment for lab based tests is sparse. Scientists behind the study published in journal Scientific Reports are optimistic that their technology could allow patients to regularly monitor their virus levels in much the same way that people with diabetes check their blood sugar levels.

But in 2016, a very different Monsegur instead passed it on to team members, who’d write up a report about the company’s insecurities—to be followed by a substantial invoice—and called it a day.

NASA says that its new material that can be given the shape of a bandage has ample of applications including on battlefields for the wounded military personnel, patients who have undergone surgery, patients who may have suffered from serious wounds and injured astronauts in space. The bandage made out of the electroactive material [PDF] has to be applied on an exterior wound. Using low level electrical stimulation generated within the material itself, the bandage promotes as well as speeds up the wound healing process and protects it from infection.

While the decline isn't substantial at somewhere around 0.7 per cent relative to current atmospheric-oxygen concentrations in the stipulated time, the decline has accelerated over the last century with increased use of fossil fuels around the world. Researchers compiled 30 years of data to construct the first ice core-based record of atmospheric oxygen concentrations for nearly a million years. To come up with historic levels of oxygen, researchers used measured ratios of oxygen-to-nitrogen found in air trapped in Antarctic ice.

The RFSU considers condom as one of the greatest inventions of the human race. Considering how a condom not only keeps both men and women safe from sexually transmitted diseases, but also unwanted pregnancies, it deserves a place in space alongside all the other inventions that have been sent to space by NASA and other space agencies.

hypnosec writes: The US Department of Energy has given a green light to the world’s most sensitive dark matter detector ever built — LUX-ZEPLIN (LZ). The dark matter detector, has received an approval for the scope, cost and schedule. LZ is named for the merger of two dark matter detection experiments: the Large Underground Xenon experiment (LUX) and the UK-based ZonEd Proportional scintillation in Liquid Noble gases experiment (ZEPLIN). LUX, a smaller liquid xenon-based underground experiment at SURF will be dismantled to make way for the new project.

Scientists at Technion-Israel Institute of Technology used simple membrane extract from spinach leaves to develop a bio-photo-electro-chemical (BPEC) cell. This BPEC cell takes in sunlight and water and sunlight as its inputs and produces electric current, hydrogen and oxygen. Researchers are hopeful that further research in this direction will one day help develop new technologies for the creation of clean fuels from renewable sources such as water and solar energy.

Researchers will bevaporizing the two meteorites using a high-powered laser and in the process collect vital data that will enable scientists to advance asteroid deflection and destruction technology thatcould one day save ourplanet.

University of Washington researchers and colleagues proved that the air during the early years of Earth exerted almost half the pressure of today's atmosphere by studying bubbles trapped in 2.7 billion-year-old rocks. For the purpose of the study, researchers needed a site that had lava that was undisputedly formed at sea level. Scientists found such a site in Australia where Beasley River had exposed a 2.7 billion-year-old basalt lava. The team drilled into the overlying lava flows to examine the size of the bubbles. Initial measurements by scientists showed that the air pressure at the time was significantly lower than current times meaning that the air was light. For more accurate results, researchers carried out x-ray scans from several lava flows and confirmed their initial findings that the atmospheric pressure at that time was less than half of today's.

The smartphone renders 3D images with motion parallax and stereoscopy to multiple users without the users requiring to wear any glasses or head tracking. Applications of HoloFlex technology include use of bend gestures for Z-Input to facilitate the editing of 3D models, playing games, among other things.
hypnosec writes: Researchers have developed a new inexpensive paper-based test to detect and diagnose Zika in just a few hours. The work was carried out by researchers at MIT and other institutions by building upon a previous technology that was developed to detect the Ebola virus. The team of scientists involved with the latest development adapted their Ebola virus detecting kit to diagnose Zika. The overall idea of the paper-based test is to develop genetic sensors and embed them in paper discs. The genetic sensors are capable of detecting 24 different RNA sequences found in the Zika viral genome. As per the design of the testing kit, if the sensor detects a target RNA sequence, it initiates a series of interactions that turns the paper from yellow to purple.
hypnosec writes: Red dwarfs have been one of the most sidelined celestial objects as far as search of intelligent extraterrestrials is concerned because astronomers have long believed that conditions around these old stars is not conducive for life. However, the SETI Institute now believes that there is a possibility that intelligent aliens may have evolved on planets orbiting red dwarfs and if they are present, they are an ideal choice to look for radio signals transmitted by these aliens. The Institute has announced its intentions of expanding the search for intelligent extraterrestrials by incorporating area in the vicinity of 20,000 red dwarf stars.

Utilizing the capabilities of four Xbox Kinects, researchers were able to quickly create a 3D image of a patient's torso providing greater information about the chest that currently used spirometer can't reveal while also helping to identify numerous other respiratory problems including collapsed lung segments or respiratory muscle weakness.

A team of scientists from University of Houston, Texas, showed in their paper published in Optical Materials Express that it is possible to use tiny gold nanodisks and light to kill bacteria in seconds paving way for potential treatment options for some common infections without use of antibiotics.

The claims have been put forward by Traffic, a UK wildlife protection monitoring group, through a report wherein they have said that just half an hour’s daily monitoring over five months by their researchers of 14 Facebook Groups in Peninsular Malaysia found more than 300 apparently wild, live animals for sale as pets, ranging from Sun Bears Helarctos malayanus and gibbons, to otters and even Binturong Arctictis binturong.
