Brain tumours may occur in children with common genetic syndrome
The frequency of brain tumours has been underestimated in children with the common genetic syndrome - neurofibromatosis type 1 (NF1), a new study has found. Brain tumours are also known to occur in children and adults with NF1. They estimated that only 15-20 per cent of kids with NF1 develop brain tumours. The study, published in the journal Neurology: Clinical Practice, found that the frequency of brain tumours in this population was more than three times higher.
NASA's Parker Solar Probe operating as planned: Scientists
Parker Solar Probe is operating as designed, and we are progressing through our commissioning activities, said Project Manager Andy Driesman of APL. This solar probe is humanity's first-ever mission into the Sun's atmosphere, called the corona. The mission has already achieved several planned milestones toward full commissioning and operations, according to the mission controllers. On August 13, the high-gain antenna, which Parker Solar Probe uses to communicate high-rate science data to Earth, was released from locks which held it stable during launch.
Plastic waste tax 'backed' by public
There is high public support for using the tax system to reduce waste from single-use plastics, the Treasury says. Treasury Minister Robert Jenrick said the government was looking at smart, intelligent incentives to get plastic producers to take responsibility. Reports suggest a levy on manufacturers and some disposable plastic products may be introduced in the Budget. This month it was revealed that most plastic food containers in shops cannot be recycled.
Silicon Valley idealism at odds with China market
The tech industry had a utopian view of the world and of itself, said Irina Raicu, director of the internet ethics program at Santa Clara University in Silicon Valley. After portraying itself as a champion of making all the world's information freely available, Google would be hard-pressed to explain taking part in online censorship in China, according to Raicu. Two years ago, it reportedly worked on a censorship tool that would filter out posts on forbidden topics there.
Scientists downgrade alert level for Hawaii volcano
Slowing activity at Hawaii's Kilauea volcano is prompting scientists to downgrade their alert level for the mountain. Scientists say this doesn't mean the eruption that has destroyed more than 700 homes since May is over. There's a crusted-over lava pond inside a fissure cone and just a few spots where lava is entering the ocean. The agency has maintained a warning alert for Kilauea since May 3, when cracks began shooting lava out of the ground in the Big Island's Leilani Estates neighborhood.
Privacy group tells FTC Google tracking violated 2011 order
A privacy group said in a letter sent to the Federal Trade Commission on Friday that Google has violated the terms of a 2011 settlement because of practices exposed in an Associated Press report this week. The Electronic Privacy Information Center said in the letter to the FTC that Google's recording of time-stamped location data-even after users have turned off a setting called Location History-clearly violates the 2011 settlement. The center lobbied the FTC to take action on Google nearly a decade ago.
US regulators target Facebook on discriminatory housing ads
Federal regulators are alleging that Facebook's advertising tools allow landlords and real estate brokers to engage in housing discrimination. The US Department of Housing and Urban Development said in an administrative complaint this week that Facebook violated the Fair Housing Act because its targeting systems allow advertisers to exclude certain audiences, such as families with young children or disabled people, from seeing housing ads. Facebook said the company doesn't allow discrimination and has strengthened its systems over the past year to prevent misuse.
Tesla shares tumble after Musk interview sparks fresh fears
In closing trade, Tesla shares skidded 8.9 percent to $305.50 following the publication of the interview with The New York Times. There were times when I didn't leave the factory for three or four days-days when I didn't go outside, Musk said. Musk acknowledged that no one read his Twitter post before he sent it, but insisted he did not regret it. If we say we simply remove Elon Musk from the situation, I don't know if that does much good.
A valley so low: Electrons congregate in ways that could be useful to 'valleytronics'
The term refers to energy valleys that form in crystals and that can trap single electrons. In the new study, researchers observed that electrons in bismuth prefer to crowd into one valley rather than distributing equally into the six available valleys. The finding confirms a recent prediction that ferroelectricity arises naturally on the surface of bismuth when electrons collect in a single valley. These valleys are not literal pits in the crystal but rather are like pockets of low energy where electrons prefer to rest.
Intensifying Hurricane Lane examined by GPM satellite
Heavy rainfall and towering cloud heights were the findings when Hurricane Lane was scanned by the Global Precipitation Measurement mission or GPM core observatory satellite on Aug 17. Lane strengthened to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. GPM passed above Lane in the Eastern Pacific Ocean on Aug 17, 2018, at 1:26 a.m. At 11 a.m. EDT, the center of Hurricane Lane was located near 11.2 degrees north latitude and 132.9 degrees west longitude.
NASA warns: Carbon monoxide clouds from California wildfires spreading throughout US
NASA has released a report pointing out how the carbon monoxide levels are slowly climbing all through the country - as far as the Eastern coast. NASA says that carbon monoxide can stay in the air for about a month and also be transported across massive distances in the meanwhile. Over the weeks covered, carbon monoxide clouds that are high in the atmosphere is seen gradually drifting east.
Hubble Space Telescope photographs the evolution of universe, captures 15,000 galaxies in single image
NASA's Hubble Space Telescope has captured a few images that show the ever-changing universe and its evolution. The field of view for these images covers about 15,000 galaxies, of which nearly 12,000 have new-born stars. This was a time when the universe was at its busiest star-creating period- 3 billion years after the Big Bang. The image closes the gap between distant galaxies, which NASA says can only be seen in infrared.
This planet's atmosphere is so hot that it has vaporised even titanium and iron in the air
Its atmosphere is filled with iron and titanium - in gaseous vapour form. The temperature on the planet is so high, that it has no clouds, just a metal-rich atmosphere. The extremely high temperatures at KELT-9b suggest that its atmosphere is a closed chemical system. The planet's extreme heat allowed the detection of iron and titanium in its individual atomic form, not bound as molecules with other metals. The intense heat spread throughout the planet's atmosphere means the iron and titanium never condense into clouds.
Water has new molecular properties: Scientists
New York, Aug 14 (IANS) US scientists have predicted a fundamental asymmetry in the mechanism of water, which had previously gone unnoticed. Prior research had indicated that two main geometrical arrangements of hydrogen bonds facilitate the hops. The study found that one of the arrangements led to significantly slower hops for OH than for H+ at four degrees Celsius.
Manned space mission doable by 2022, says ISRO
At a mission cost of Rs 10,000 crore, the agency's largest ever, India could become the fourth country to send a human to space. Since 2004, when the Indian Space Research Organisation (Isro) first prepared a plan for human spaceflight, the agency has been developing technologies that are building blocks for such a mission. What we need is to invest in building the systems and the infrastructure, Isro chairman K Sivan said, allaying concerns over the tight schedule to achieve the mission.
Scientists find 99-million-year-old beetle trapped in amber with pilfered pollen from cycad
While researchers already had an idea about the fact that modern cycads were pollinated by beetles, this is the first time that they have discovered a 99-million-year-old beetle trapped in amber from Myanmar. The little fellow was preserved with pilfered pollen from a cycad. Dr Cai examined the beetle thoroughly and minutely and spotted dozens of pollen's specks, some of which were even clustered in clumps, alongside the beetle.
H-1B use skyrocketed among Bay Area tech giants
The data show the importance of H-1B workers to the tech industry, which has long lobbied to increase the number of highly skilled foreign workers. The number of H-1B approvals at Intel in Santa Clara rose 19 percent and Cupertino-based Apple received 673, a 7 percent increase. Experts say the data also doesn't show how many additional H-1B contractors tech companies may get from staffing agencies or outsourcing companies.
Alexa, Cortana finally get the conversation going
Amazon's Alexa and Microsoft's Cortana are coming soon to a smart device near you together, with new integrated features that allow the digital assistants to talk to each other. Alternately, Cortana will be able to ask Alexa to set the temperature of the room through an internet-connected thermostat and access many of the third-party skills other companies have built into Alexa. The integration will bring more work-focused functions to Alexa through Cortana and general life capabilities to Cortana.
Water-worlds are common: Exoplanets may contain vast amounts of water
Scientists have shown that water is likely to be a major component of those exoplanets which are between two to four times the size of Earth. Moving deeper, one would expect to find this water transforms into high-pressure ices before we reaching the solid rocky core. The beauty of the model is that it explains just how composition relates to the known facts about these planets.
Chemists develop contaminant detection technique for heparin
For example, Dwyer said, the new detection technique could serve as a quality assurance tool across the pharmaceutical industry, especially with an increased push to develop more sugar-based drugs, such as heparin. To develop the new detection technique, Dwyer turned to a sensing method proven in the sequencing of DNA and proteins. With the 2008 crisis, researchers had managed to identify and detect the oversulfated chondroitin sulfate contaminant, which was nearly identical to the heparin.
