I never expected we could find a dinosaur in amber. The delicately feathered 1.4-inch tail with bone and tissue intact was frozen in time in a piece of amber originally discovered in a mine in northern Myanmar. It was eventually found last year at a street market by paleontologist Lida Xing of Beijing's University of Geosciences. In a groundbreaking find, scientists have discovered the preserved tail of a tiny, 99-million-year-old feathered dinosaur.
Donald Trump's presidential transition team pushed back Saturday against reports that Russia was caught trying to tip the November election to the Republican and challenged the veracity of US intelligence agencies investigating the campaign-season cyberattacks. Spicer also denied a report in The New York Times that Republican National Committee systems had been breached during the election. He said the RNC has worked with intelligence agencies that have told it with certainty that we haven't been hacked.
The French government has announced an anti-pollution plan, including a financial boost to buy electric vehicles, as Paris and other cities in the country are emerging from a particularly severe episode of air pollution. Environment Minister Segolene Royal said Saturday professionals will get a bonus of up to 10,000 euros ($10,600) if they scrap their old diesel light commercial vehicles or taxis for electric ones, starting next month. Royal also said she will ask to exempt electric vehicles from highway tolls.
A new replica of the stunning Lascaux cave paintings was unveiled Saturday in the Dordogne region of southwest France, more than seven decades after the prehistoric art was first discovered. The spectacular prehistoric art is thought to be 18,000 years old and has been on UNESCO's list of world heritage sites since 1979. The new version marks the first time that we've reconstructed the entire Lascaux cave, said Jean-Pierre Chadelle, an archaeologist working with the Dordogne regional authority.
A new campaign led by medical professionals is calling for all diesel cars to be banned from London. Doctors Against Diesel claim 9,400 Londoners a year die prematurely from breathing in toxic fumes from diesel engines. Paris, Madrid, Mexico City and Athens have committed to a ban on diesel vehicles by 2025. Doctors Against Diesel - comprising doctors, nurses and health professionals - are calling for Sadiq Khan, Mayor of London, to commit to phasing out diesel vehicles from London.
UNIST has taken a major step toward laying the technical groundwork for developing next-generation high-intensity accelerators by providing a new advanced theoretical tool for the design and analysis of complex beam lines with strong coupling. Accelerators are devices that accelerate the movement of atomic-sized particles, such as electrons, protons, and ions to very high energies. The next-generation high power accelerators, on the other hand, refer to accelators for high intensities and high energies.
Japan has launched a cargo ship which will use a 700m -long tether to remove some of the vast amount of debris from Earth's orbit. The tether, made of aluminium strands and steel wire, is designed to slow the debris, pulling it out of orbit. The cargo ship will also deliver supplies to the International Space Station.
With 105,000 suspected Zika cases, Colombia has had the second-largest Zika epidemic after Brazil. As of Thursday, Brazil had reported 2,211 cases of microcephaly in which Zika infection had been confirmed to the World Health Organization, while Colombia had reported only 60. The study released by the CDC found 476 cases of microcephaly in Colombia between January and mid-November. One theory - still unproven - is that Colombia had fewer microcephaly cases than expected because many fearful women aborted their pregnancies, legally or illegally.
Prime Minister Justin Trudeau announced on Friday that Canada would introduce nationwide carbon pricing in 2018. Mr Trudeau worked out a deal for the plan, which aims to reduce carbon emissions by putting a price on them, after meeting with the premiers of Canada's 10 provinces and three territories. Over the next five years, the price would rise to 50 Canadian dollars per metric ton, or about $38.
Google and the Cuban government have struck a deal giving Cubans faster access to the internet giant's content, two people familiar with the deal say. Eric Schmidt, chairman of Google's parent company, will formally sign the deal Monday morning in Havana, the two people said. The deal allows Cubans access to a network of servers called Google Global Cache that stores content from Google-run sites like Gmail and YouTube in locations around the world.
The cryogenic energy facility stores power from renewables or off-peak generation by chilling air into liquid form. The company behind the scheme, Highview Power Storage, believes that the technology has great potential to be scaled up for long-term use with green energy sources. The intermittent nature of green sources has seen researchers focus on trying to improve energy storage. Cryogenic storage works by using renewable or off-peak electricity to cool air down to -190 degrees C, which turns it into a liquid.
The enzyme known as ALOX15 plays a crucial role in the production of anti-inflammatory and pro-resolving lipid mediators. As mammals have evolved, this enzyme has undergone changes to both its structure and function. This discovery might suggest that the enzyme's structure has evolved to enable it to better control inflammation and to speed up the healing process. Results from this study have been published in the current issue of the journal Proceedings of the National Academy of Sciences.
