Washington, Jun 23 - A team of engineers has developed micro-tentacles for tiny robots, so that they can handle delicate objects.
Lead author Jaeyoun (Jay) Kim from Iowa State University said that most robots use two fingers and to pick things up, they have to squeeze, but these tentacles wrap around very gently.
The paper describes how the engineers fabricated microtubes just 8 millimeters long and less than a hundredth of an inch wide. They're made from PDMS, a transparent elastomer that can be a liquid or a soft, rubbery solid.
Washington, Jun 23 - As per a new study, early Europeans had recent Neanderthal ancestors.
Howard Hughes Medical Institute geneticists analyzed ancient DNA from the jawbone of a human who lived in Europe about 40,000 years ago, providing the first genetic evidence that humans interbred with Neanderthals in Europe.
Researcher David Reich said that they know that 45,000 years ago, the only humans in Europe were Neanderthals. But 35,000 years ago, the only humans in Europe were modern humans. This is a dramatic transition.
Washington, Jun 23 - Researchers have discovered intense radio emission from a tiny binary star, which calls for a review of stellar models.
As per the University of Valencia study, this small binary star is known as AB Doradus B and is located in the AB Doradus star system, consisting of two pairs of stars. Stars normally emit light that can be seen with the naked eye or through telescopes, but some also emit radio waves, similar to those from televisions, mobile phones or microwave ovens.
Co-author Jose Carlos Guirado said that these emissions have made it possible to calculate the mass of the star, which is usually complex, but when the star is accompanied by another, its orbital motion gives us an accurate way to determine it, as Kepler's laws establish.
Washington, June 22 - Microsoft has given a makeover to its Bing video search feature.
According to the Verge, new features include larger, easier-to-identify video thumbnails and the users can even preview videos straight from the results to get an idea of what they are looking at. For that, the users just have to move their cursor over a result to watch a small bit of the video.
In addition, Bing shows additional information on each result. Users can now see the view count, upload date and up-loader before clicking to the result.
Music searches will now show a module up at the top for the artist with a photo and a list of other top songs. The suggested videos will be shown half-way down the page in another module, with more recommendations.
Washington, June 22 - Scientists have taken inspiration from the flight of owls to develop "quieter" wind turbines and planes.
Early tests of a prototype coating for fan blades, which mimics the intricate structure of an owl's wing, have demonstrated that it could significantly reduce the amount of noise produced by wind turbines and other types of fan blades, such as those in computers or planes.
The addition of this new surface would mean that wind turbines could be run at much higher speeds - producing more energy while making less noise. For an average-sized wind farm, this could mean several additional megawatts worth of electricity.
Washington, June 22 - The Iranian parliament has voted to oppose the government military sites' inspections as part of a multi-nation agreement to limit the country's nuclear program which may complicate the final deal ahead of a June 30 deadline.

The official also said that US will allow Iran to manage the process by themselves and that the final deal must include adequate access and transparency.

Washington, Jun 21 - Researchers have discovered how an immune system protein, called AIM2 (Absent in Melanoma 2), plays a role in determining the aggressiveness of colon cancer.
Scientists at St. Jude Children's Research Hospital found that AIM2 deficiency causes uncontrolled proliferation of intestinal cells and also discovered that AIM2 influences the microbiota, the population of gut bacteria, apparently fostering the proliferation of "good" bacteria that can protect against colon cancer.
Team leader Thirumala-Devi Kanneganti said that the findings could have important applications for prevention, prognosis and treatment.
Washington, June 21 - Days after a white gunman shot nine people dead in an African-American church in South Carolina's Charleston area, U.S. President Barack Obama has claimed that gun violence in America is much worse in comparison to other developed nations like France, Israel and Japan.

The statement came just days after Obama condemned Thursday' attack, saying that this type of mass violence did not happen in other advanced countries.

Washington, June 20 : Giant car companies are working on technology that will allow cars in future to read driver's mind, health and predict their actions.
They're all elements of different projects that Jaguar Land Rover has been trying to accelerate in order to make its cars much smarter and safer, the Verge has reported.
Jaguar wants its cars to be able to tell if a person was paying attention to the road or off daydreaming, so that it could try to make the driver alert again should they lose focus, and that's possible by monitoring for brainwaves that indicate a person is tired or distracted.
