The Green New Deal, introduced last month by Democrats, marked the first formal attempt by lawmakers to define legislation to create big government-led investments in clean energy like wind and solar power, infrastructure and social programs. Republicans have used the plan to try to sow discord within the Democratic Party, painting their rivals as shifting far to the left and embracing extreme policies. Democratic Senator Edward Markey, who unveiled the plan with Representative Alexandria Ocasio-Cortez, has called the vote a "sham." He said the Green New Deal was meant to spur debate during the 2020 presidential election campaign on the intricate problem of how to tackle climate change while boosting the economy, not to force the party to take sides in a quick vote.
Apple derived 15 percent of its revenue from services in 2018, while more than 60 percent came from its iPhone, according to data compiled by Bloomberg. Shares of Apple rose 1.2 percent before the bell on Tuesday, on pace to snap a two-day skid. “Big picture, this strategy aligns with our thesis that Services, not devices, hold the key to Apple revenue and profitability growth over the next 5 years.” However, while the breadth of the services that were launched was “impressive,” the lack of pricing detail makes it difficult to evaluate the financial impact.
Archaeologists have uncovered more than 100 ancient inscriptions carved into rock at Wadi el-Hudi, where the ancient Egyptians mined amethyst.In addition to the carved-rock inscription, the researchers also found 14 stele (inscriptions carved on a stone slab or pillar) and 45 ostraca (inscriptions written on pieces of pottery).Analysis of the newfound inscriptions is underway. So far, archaeologists can tell that many of the inscriptions date back around 3,900 years, to a time that modern day archaeologists call the "Middle Kingdom." Many of the ostraca date back around 2,000 years, to around the time that Rome took over Egypt. [See Photos of the Ancient Egyptian Mining Site & Inscriptions]Amethyst became widely popular in Egypt during the Middle Kingdom, a time when the pharaohs of Egypt learned that Wadi el-Hudi is a good source for the material. "Once the [pharaohs] found it, they kind of went bonkers to go get it," Kate Liszka, the director of the Wadi el-Hudi expedition, told Live Science. During the Middle Kingdom, "they were bringing it back and making it into jewelry and doling it out to their elite and their princesses."Though Wadi el-Hudi was surveyed in the past by other scholars, little excavation has been done and the surveys missed many inscriptions. "The site is just so full of inscriptions behind every boulder and around every wall that they missed a lot of them" Liszka said.The team is using 3D modeling, reflectance transformation imaging (RTI) and photogrammetry, among other techniques, to help find new inscriptions, map archaeological remains and reanalyze inscriptions discovered by scholars who surveyed Wadi el-Hudi in the past. This work has taken on a greater urgency as modern-day gold mines have opened in the area, causing damage to archaeological remains. Many mysteriesThe team is hoping that the inscriptions, along with other discoveries made during the excavations, will shed light on the many mysteries surrounding Wadi el-Hudi.One of more than 100 inscriptions that were recently discovered by researchers at Wadi el-Hudi. Photo courtesy Wadi el-Hudi ExpeditionFor instance, it's not clear if the miners were working at the site of their own free will. "I don't know if I'm excavating a legitimate settlement where people were treated well or if I'm excavating a prison camp," Liszka said. Some of the inscriptions say that the miners were proud of their work, suggesting that they may have been there of their own free will. Also, so far, no bodies have been found, suggesting that anyone who died was brought back to the Nile Valley for burial rather than left out in the desert, researchers said.The inscriptions also show that there are places where groups of soldiers were looking down at the mines, leading researchers to wonder if these soldiers were protecting the miners or making sure the miners kept working. One inscription shows two soldiers wrestling each other while passing time.Another mystery: How did the ancient Egyptian government get water to the miners? The nearest possible well is 1.9 miles (3 kilometers) away from Wadi el-Hudi, and it's possible that it wasn't in use long ago. "Best-case scenario, they were carrying water for 1,000 to 1,500 people a minimum of 3 km, but possibly in from the Nile [River]," which is about 18.6 miles (30 km) away, Liszka said.During the excavation, the team found a mysterious, 3,400-year-old stela written in the name of a senior official named Usersatet, who was viceroy of Kush, a region to the south of Egypt. It dates to a time when there was no mining activity at Wadi el-Hudi and the site had been abandoned. This leaves archaeologists with the question of why someone bothered to drag the stela 18. 6 miles into the eastern desert and leave it at Wadi el-Hudi. * The 25 Most Mysterious Archaeological Finds on Earth * 25 Cultures That Practiced Human Sacrifice * Photos: Mummies Discovered in Tombs in Ancient Egyptian CityOriginally published on Live Science.
Nasa has cancelled the first ever all-female space walk outside the International Space Station after it emerged it did not have enough suits to fit women. In a blow to what would have been one great leap for womankind, the plan for Christina Koch and Anne McClain to change a battery on the station's exterior had to be called off. It would have been the first time two women carried out the space walk, rather than a team comprising a man and a woman. In a press release, Nasa said only one of the astronauts would take part in the space walk on Friday March 29 as a result of the equipment shortage. Earth will learn a lot during his busy week on @Space_Station - today he kept me company while we checked our suit sizing to account for space growth (I am 2 inches taller than when I launched!), then we did some translation adaptation. pic.twitter.com/A89tJauyQu— Anne McClain (@AstroAnnimal) March 4, 2019 "Koch had been scheduled to conduct this spacewalk with astronaut McClain, in what would have been the first all-female spacewalk," it said. "However, after consulting with McClain and Hague following the first spacewalk, mission managers decided to adjust the assignments, due in part to spacesuit availability on the station. McClain learned during her first spacewalk that a medium-size hard upper torso – essentially the shirt of the spacesuit – fits her best. "Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it." Ms McClain is expected to do her space walk on a different date, April 8, which means the plan for an all-female space walk has fallen through. The first woman to perform a spacewalk was Svetlana Savitskaya, a Russian Soviet astronaut who made the bold journey 35 years ago. More than 500 people have been into space, but only 11 per cent have been women, according to Reuters news agency. �� �������������� ������������ ���� ������ ����’�� ���������� ��������… pic.twitter.com/2fDXJX94wa— Anne McClain (@AstroAnnimal) March 25, 2019
The Chinese Internet giant wants to cut the interest margin of the facility that it signed in May 2016 by 25 basis points to 85 basis points over Libor, said people familiar with the matter. Alibaba declined to comment in an emailed statement. Tencent also pushed down its syndicated loan margins by 25 basis points in the past.
The social media company’s move is part of a follow-on investigation into Iran-linked coordinated inauthentic behavior on its platform after announcing similar measures earlier this year. On Tuesday, Facebook said it had removed 513 pages, groups and accounts on Facebook and Instagram appearing to target users in Egypt, India, Indonesia, Israel, Italy, Kashmir, Kazakhstan and more broadly across the Middle East and North Africa. Facebook says it has shared information about the investigation with U.S. law enforcement.
Former President and CEO of Danish toymaker Lego, Kjeld Kirk Kristiansen, will step down from the the board of the toymaker at the general meeting in April, the company's owner said on Tuesday. "This is a completely natural next step in the generation shift," said Chief Executive Soren Thorup Sorensen of Kirkbi, the family holding company behind Lego. Kjeld Kirk Kristiansen will remain chairman of the board at Kirkbi and vice chairman of the Lego Foundation, the company said.
Kaspersky Lab said in a report attackers used stolen digital certificates in 2018 to insert malicious code into the Taiwanese PC giant’s live software-update system, which may then have installed back-doors on computers. The company had since helped customers fix the problem, patched the vulnerability and updated their servers, Asus said in a separate statement. Cyber-attacks are on the rise globally as online information becomes increasingly valuable and connected devices proliferate.
Uber will pay Dubai-based Careem $1.4 billion in cash and another $1.7 billion in convertible notes when the deal closes, the two companies said in a statement. Bloomberg had previously reported some details of the deal, which is expected to close in the first quarter of 2020. The deal comes as San Francisco-based Uber is preparing to file in April for an initial public offering, people familiar with the matter have said.
A 2.3 percent jump in global energy demand last year outstripped the expansion of renewables and helped drive record-high greenhouse gas emissions, the International Energy Agency (IEA) said Tuesday. Fossil fuels satisfied nearly 70 percent of that growth for the second year running, with natural gas accounting for 45 percent of the rise in energy consumption, according to the Agency's Global Energy & CO2 Status Report. Double-digit growth in solar and wind power generation -- 31 percent for solar -- was still not fast enough to meet soaring electricity demand that also pushed up the use of coal, the most carbon-intensive of fuels.
