Richard Spencer, other white supremacists lose Twitter verification
A week after the ruckus over blue checks on Twitter, the company has updated its policy on verifications and revoked the verifications of some white supremacists. Richard Spencer, Jason Kessler and others have lost the blue check marks next to their names on Twitter. Such activity is also against the company's broader rules, and could result in the suspension of a Twitter account. Jason Kessler has written for the Daily Caller and organized the Charlottesville white supremacist rally that turned deadly over the summer.
Strain-free epitaxy of germanium film on mica
Germanium (Ge) is generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers at Rensselaer Polytechnic Institute in the United States demonstrate an epitaxy method that incorporates van der Waals' forces to grow Ge on mica. The researchers chose mica as the substrate on which to grow the Ge film because of its atomically smooth surface, which is free of dangling bonds.
Species in the north are more vulnerable to climate change
The research findings could change our perception of which species are likely to be most affected by climate change. High-latitude species could have a less flexible physiology than previously thought and thus be more vulnerable to climate change, he says. Individuals from both species lived in laboratory environments corresponding to the seasonal climate in northern Sweden and central Europe respectively. The findings show that the central European species is always best at acclimating regardless of the type of climate.
'First industry built PSLV by 2020'
The Indian Space Research Organisation (ISRO) is preparing to hand over the entire gamut of launch vehicle manufacture to domestic industry by 2020. Until now, public and private industries have only supplied devices, components and sub-systems for ISRO's launch vehicles, including the PSLV and the GSLV. By 2020, we hope to have the first completely industry-built PSLV, Vikram Sarabhai Space Centre (VSSC) Director K Sivan said here on Friday.
Inventor Brian Krohn combats snoring, creates wizard tools
Brian Krohn has developed brain surgery tools, pioneered biodiesel innovations and briefed members of Congress on how to turn waste oils into energy. He's CWO for a startup that will make a wizard staff that actually does wizard stuff. You can do it for snoring and magic wizard staffs and brain surgery, he said. He's just one of those people who are naturally innovative, said Davis Fay, an engineer working with Krohn on the Magic Wizard Staff project.
India, Japan mulling possible joint lunar mission: ISRO chief
Discussions are underway between India and Japan on making use of space segment for providing inputs on weather-monitoring parameters and also on joint lunar mission, ISRO Chairman A S Kiran Kumar said today. Kumar said there is a visible change in the relationship between space agencies of India and Japan, which are both working together for looking at possible future cooperative mission. Unless you are able to reach there at lower costs, many of the activities including power generation, will not be feasible, he said.
Greenpeace launch anti-Coca-Cola ad to highlight plastic pollution
As Coca Cola launch their new Holidays are coming Christmas TV advertisement, some of the brands fans have been viewing a version thats a little more realistic. In an attempt to take advantage of Cokes huge PR push at this time of year, Greenpeace produced their own Coke Christmas ad highlighting an unfortunate side effect of bottled fizzy drinks.
Fishing is 'best argument for seagrass'
The importance of seagrasses is further emphasised in a new report that looks at how they underpin fishing worldwide. Our study is really the first to show just how important seagrass meadows are to fishing, explained the researcher from Swansea University in the UK. Now there is growing evidence globally that many fisheries associated to seagrass are unrecorded, unreported and unmanaged, leading to a tragedy of the seagrass commons.
New iPhone X teardown study estimates cost to build Apple's deluxe phone
The United Kingdom-based analytics company IHS Markit tore apart the iPhone X to examine how much each part costs. It concluded the overall cost to construct an iPhone X at 64 gigabytes was $370.25, the most expensive in iPhone history and $75 more than its most expensive predecessor, the iPhone 8 Plus with 256 gigabytes. When compared to its direct competitor, the Samsung Galaxy S8 with 64 gigabytes of memory, the iPhone X costs $68 more to construct.
Can precum lead to pregnancy?
One such aspect is pre-ejaculatory fluid or precum, and whether it has the potential to impregnate women. According to various studies, precum usually comprises of sperm that are likely to be dead and immobile, but some researches have seen living sperms present in this fluid as well. As per findings, some men often leak their sperm in the precum. Yes, precum has a high potential to infect you with STDs if your partner has it.
No more deer in the headlight: Study finds large mammals do use road crossing structures
Large mammals crossing US Highway 93 are more likely to use wildlife crossing structures than move past a random location in the surrounding habitat, new research shows. The findings, published in open-access journal Frontiers in Ecology and Evolution, are a first step towards a better understanding what makes road crossing structures effective. This indicates that the structures were successful at improving or maintaining the habitat connectivity for wildlife across the barrier created by the highway.
NIR-driven H2 evolution from water: Expanding wavelength range for solar energy conversion
Hydrogen can be produced by splitting water (H2O) into hydrogen (H2) and oxygen (O2). There are many ways to do this, but among the cleanest - hence most attractive - is using solar cells. Solar cells must absorb light of particular wavelengths, depending on how much energy the cell needs to drive the reaction. Now, researchers at Kyushu University in Japan and its Institute for Carbon-Neutral Energy Research (I2CNER) have potentially solved this problem.
Performance appraisal success depends on frequent feedback and good standard setting
It shows that acceptability of appraisals is enhanced when feedback is frequent and standards are set and clear to employees but also that these two things have a synergistic relationship, so feedback has a greater effect when standard setting is good. Professor Shaun Pichler commenting on the results said: People like receiving feedback, yet all too often employees do not get it.
What is the Paris Agreement?
The Palestinian Authority has since joined the UN's climate convention and the Paris Agreement, bringing the total to 196. The United States is now the only country to opt out, though it cannot formally withdraw until November 2020. In 2018, and every five years thereafter, countries will take stock of the overall impact of their efforts to rein in global warming. It urges and requests all countries to update emissions-cutting pledges by 2020 and every five years after that.
What grosses out a chimpanzee?
In their natural habitats, chimpanzees are known to pick up seeds from feces and re-ingest them. These behaviors usually involve their own fecal matter, or that of their closest family members. If presented with feces and other bodily fluids from others, however, that's an entirely different story. These experiments hint at the origins of disgust in humans, and help us better understand the protective function of this emotion concludes Cecile Sarabian.
Warmer water signals change for Scotland's shags
An increasingly catholic diet among European Shags at one of Scotland's best-studied breeding colonies has been linked to long-term climate change and may have important implications for Scotland's seabirds, according to research led by the Centre for Ecology & Hydrology on November 16 2017. Three decades of data from the Isle of May, off Scotland's east coast, found that the proportion of sandeels - the bird's usual fayre - declined by 48% between 1985 and 2014.
Want safe travels? Find freeways with these features
New BYU research commissioned by the Federal Highway Administration (FHWA) shows a number of highway features that make accidents less likely. Among them are some that are intuitive: minimal hills and curves, paved right shoulders and concrete-barrier medians. I think the speed limit was the shocker, said statistics professor Matt Heaton, who coauthored the study, recently published in Statistical Modelling. One method examined roadway features correlated with incidences of crashes, and another looked specifically at high-crash areas, controlled for the factors in the other analysis.
