As per the algorithm, tweet words "lying," "liberal," and "illegal" indicates a vote for Republican candidate Trump, while words "single," "humanity," and "rights", predicts a vote for Democratic rival Clinton.Online tool, Tweetcast, can predict vote in upcoming US Presidential elections
Nanoparous magnesium ferrite was used to split water into hydronium (H3O) and hydroxide (OH) ions. Silver and Zinc were used as electrodes to make a cell that produces electricity.
Tasmanian devils are currently under serious threat from Devil Facial Tumour Disease (DFTD), a highly infectious parasitic facial cancer that has wiped out more than 70 percent of the species.
The study was conducted by the researchers at Hasselt University in Belgium. The study was published in the journal BMC Medicine.
This is the first time where a bio-waste-derived electrode has been used as cathode in a quantum dot sensitised solar cell device.
The bandage could be used by military personnel wounded in the field, patients who have undergone surgery or who have suffered a serious wound and astronauts in space.
If scientists can discover where these balls come from, it could also explain other weird shapes seen in the cloud of gas around dying stars, some of which have been difficult for scientists to explain.
The findings, in chimpanzees, bonobos and orangutans, are the first to clearly demonstrate that apes can predict another’s beliefs, even when they know that presumption is false.
GSAT-18 is designed to provide continuity of services on operational satellites in C-band, Extended C-band and Ku-bands. It will also help in replacing the currently ageing satellites.
The baby was born using the new and controversial technology, called mitochondrial donation, which incorporates DNA from three persons. The five-month-old boy has the usual DNA from his parents, and a small amount of genetic code from a donor.
Using ultraviolet images taken by Hubble, a space telescope that was launched in 1990, the potential plumes were seen around the southern edge of Europa and appear as dark fingers or patches of possible absorption.
The FAST is a radio telescope located in the Dawodang depression, a natural basin in Pingtang County, Guizhou Province, southwest China.
The satellites that were carried into space included the primary payload SCATSAT-1 of India, and seven other customer payloads (five foreign and two domestic).
A novel interpretation of Raman spectra will help the 2020 Mars rover select rocks to study for signs of life.
The researchers used stem cells taken from actual adult human lungs to coat tiny sticky hydrogel beads. The beads eventually grew and self-assembled to envelope the hydrogel beads, which were all placed inside linked wells. The resulting structure produced evenly distributed three-dimensional patterns consistent with actual air sacs like those in human lungs.
The supercomputer has a power of 250 teraflops and a 300 terabyte capacity and can be used in areas like computational chemistry, computational fluid dynamics, civil engineering structures, etc.
By extending the contract, India's exclusive rights for exploration of Polymetallic Nodules in the allotted Area in the Central Indian Ocean Basin will continue.
In the latest issue of Nature Communications, a group of researchers described a prototype of the system, which they tested on a stack of papers, each with one letter printed on it.
OSIRIS-REx is United States’ first mission to collect samples from an asteroid and return to Earth. It hopes that the collected samples would help them in learning more about the origins of life.
Satellite INSAT-3DR will have about ten years of operational life and will provide a variety of meteorological services to the country.
For the first time, the researchers found that gram-positive Group B Streptococcus (GBS) bacteria produce small balloons called membrane vesicles. These vesicles contain toxins that destroy foetal and maternal cells. They also kill the collagen that keeps the cells together.
It was the second time in just over a year that SpaceX has lost a Falcon 9 rocket, which is slated to launch NASA astronauts for the first time in 2017.
With this, India has joined the select league of four space faring nations that have demonstrated flight testing of Scramjet engines.
Alloy is a headset that uses the RealSense technology enabling people to use their hands to interact with elements of the virtual world. There is no need for cables to connect to the computer.
This flight of the 92-metre ship, nicknamed the Flying Bum for its shape, lasted for about half an hour. The aircraft completed a series of flight manoeuvres and landed safely.
NASA and industry partners will expand commercial development of space in low-Earth orbit. In addition, they will also work towards improving deep space exploration capabilities to support more extensive human spaceflight missions.
The study was conducted by team of researchers including Fumito Kawakami, Masaki Tomonaga and Juri Suzuki of Kyoto University in Japan and was published on 3 August 2016.
A team of researchers led by Professor Sathees Raghavan from the Department of Biochemistry, IISc, Bengaluru revealed that endosulfan breaks in DNA strands and disturbs the damage response mechanism found in cells, which leads to compromised DNA strand repair.
Tiantong-01 is the first satellite of China's home-made satellite mobile telecom system, and a key part of the country's space information infrastructure.
The researchers used a metal compound called tungsten diselenide, which was fashioned into nanosized flakes to maximize the surface area and to expose its reactive edges.
