Comments Off on Hyundai’s first fully-electric SUV boasts 292-mile range

Hyundai just unveiled their electric SUV , the Kona Electric , and it can travel around 292 miles on a single charge. The company says this vehicle will be the “first fully-electric subcompact SUV on the European market,” and features progressive design , including a closed grille on the front of the car that enhances aerodynamics. Hyundai will be releasing short- and long-range models of the Kona Electric, boasting ranges of 186 and 292 miles respectively, according to The Verge . The short-range model includes a 99 kilowatt (kW) electric motor and 39.2 kilowatt-hour (kWh) battery, and reaches 60 miles per hour (mph) from zero in around nine seconds. There’s a 150 kW motor and 64 kWh battery in the long-range model, which can accelerate from zero to 60 mph in 7.6 seconds.

Via a standard AC outlet, the short-range model will charge up fully in around six hours and 10 minutes, and the long-range model will charge up in around nine hours and 40 minutes due to the larger battery. Smart technology can be found throughout the vehicle. Both models will be equipped with semi-autonomous driving and safety technology like adaptive cruise control, blind spot warning, and lane keeping assist. A heads-up display provides speed and navigation information. There’s a wireless charging pad for Qi-enabled smartphones in the center console. The car also includes a button type shift-by-wire system so drivers can shift to park, neutral, forward or reverse with the press of a button. The car even boasts 21 exterior color combinations — with a two-tone roof and seven distinctive exterior colors, there’s plenty of room for customization. The Kona Electric is set to hit Europe and South Korea later in 2018. Hyundai has not yet said how much the car will cost. + Hyundai Kona Electric + Hyundai Kona Electric Highlights Via The Verge Images via Hyundai

Breast cancer spread connected to amino acid in asparagus

Comments Off on Breast cancer spread connected to amino acid in asparagus

Scientists have linked the spread of the disease breast cancer in mice to a compound that’s in asparagus and several other foods, The Guardian reported . Studies with mice revealed asparagine drives the advance of the cancer , and when researchers reduced asparagine, the amount of “secondary tumors in other tissues” dropped. Cancer Research UK Cambridge Institute director Greg Hannon told The Guardian, “This is a very promising lead and one of the very few instances where there is a scientific rationale for a dietary modification influencing cancer.” Research with mice showed the amino acid asparagine is important for breast cancer to spread, and scientists think the process could be similar in humans. Researchers found that blocking the amino acid hampered the spread of the cancer. Hannon said in a statement , “It could be that manipulating levels of asparagine in the body might be used as a way to boost a patients’ cancer treatment.” Related: Many anti-aging products contain ingredients that can cause breast cancer The researchers blocked asparagine in mice tested, which had an aggressive type of breast cancer, to reduce the cancer’s ability to spread with the drug L-asparaginase. Giving the mice a low-asparagine diet worked to a lesser extent, according to The Guardian. There’s still a lot work to be done. The Cancer Research UK Cambridge Institute cautioned research is in the early stages and “doesn’t form the basis for DIY diets at home.” This work also doesn’t seem to offer a cure for cancer; per the press release, “So far the story suggests that lowering asparagine levels blunts the ability of cancer cells to spread in mice, but doesn’t affect the original tumor.” Lowering asparagine didn’t prevent breast tumors from forming, the researchers found. Hannon said, “The difficulty is finding ways to study this in the lab that are relevant to patients. It’s a challenge, but I think it’s worth pursuing.” The journal Nature published the research online this week . 21 scientists at institutions in the United Kingdom, Canada, and the United States contributed. + Cancer Research UK Cambridge Institute + Nature Via The Guardian Images via Stephanie Studer on Unsplash and Tambako The Jaguar on Flickr

Comments Off on Paris banned all cars for a day to highlight pollution issues

Pedestrians and cyclists cheered yesterday as Paris closed all of its streets to cars. The government held a Car Free Day and the streets filled with bikers, walkers, and roller-bladers instead of smog. Paris held a Car Free Day in 2015 and 2016 as well. But this was the first time they extended the boundaries to include the entire city . From 11 AM to 6 PM local time, cars were asked to stay off the streets – with exceptions made for emergency vehicles, taxis, and buses. The Paris City Council hosted Car Free Day, together with collective Paris Sans Voiture , or Paris Without Car, which is behind the city-wide car-free idea. Related: Activists Show What it Would Look Like if Bikes Took Up as Much Room as Cars Pollution from cars is often an issue in France’s capital – the Associated Press said mayor Anne Hidalgo was elected after promising to slash air pollution and cut traffic . The government’s statement on the day said one of the Car Free Day’s objectives was “to show that cities can and must invent concrete solutions to fight against pollution” coming from road traffic. They encouraged people to travel by scooters , skates, bikes , or walking . The symbolic event also brought results. The government said Airparif Association conducted independent measurements during the Car Free Day using sensors and a bicycle outfitted with measuring instruments. They saw “an increased decrease in nitrogen dioxide levels along major roads” and “access roads to the capital.” Meanwhile, the Bruitparif Observatory looked at noise with the help of 11 measurement stations. They saw sound energy decreased 20 percent on average, as compared against a regular Sunday. Via Paris and Associated Press/NBC News Images © Henri Garat – Mairie de Paris

Former NASA chief scientist says Americans ‘under siege’ from fake climate news

Comments Off on Former NASA chief scientist says Americans ‘under siege’ from fake climate news

The science is in on climate change – it’s real and hurting Earth right now. But not all Americans are aware of the threat, according to former NASA Chief Scientist Ellen Stofan. She said the country’s citizens are “under siege by fake information that’s being put forward by people who have a profit motive.” Stofan said the science on climate change is unequivocal. Nevertheless there are still deniers of the phenomenon in the United States – some holding top government positions. Stofan said disinformation and half-truths designed to confuse people have been spread about climate change, and now many people in the country are unaware of the pressing consequences of carbon emissions continuing as is. Related: Americans don’t trust climate change science because of fossil fuel industry’s disinformation She said oil and coal companies have been behind the disinformation, telling The Guardian, “Fake news is so harmful because once people take on a concept it’s very hard to dislodge it.” Stofan said she saw “an erosion of people’s ability to scrutinize information” across the political spectrum, not just on the left or the right. “All of us have a responsibility. There’s this attitude of ‘I read it on the Internet therefore it must be true,” she said. Stofan said the American science community has been realizing the threat of climate change fake news during the past six months, and are working to communicate more with the public and share information with the press. During her career Stofan pointed to planetary science as important for understanding the environment here on Earth. She said planetary science has offered proof that atmospheric carbon dioxide results in a warmer climate . She finds similarities between Earth’s carbon emissions and the runaway greenhouse effect on the planet Venus . Venus once had oceans but now the volcano and lava plain-strewn planet has temperatures nearing 500 degrees Celsius – Space.com described the planet as “our solar system’s analog to hell.” Stofan told The Guardian, “We won’t go all the way to Venus, but the consequences of putting more and more CO2 into the atmosphere are really dire. There are models that suggest if we burn off all our fossil fuels , the Earth would become uninhabitable for humans.” She said our first job should be to keep Earth habitable.

Comments Off on Scientists unveil first printable, stable perovskite solar cell good for 10K hours

The mineral perovskite has been touted as the next big thing for renewable energy , potentially giving solar cells a 31 percent maximum efficiency – but water-soluble and perovskite solar cells typically don’t last long in the real world. 11 scientists at institutions in Switzerland and Italy may have finally achieved what researchers have been working towards since around 2009: a stable perovskite solar cell. Their solar cells stayed stable in real world conditions for longer than a year. Perovskite solar cells have already been built with an efficiency of more than 22 percent, but that’s in a laboratory. Oxygen and moisture go to work on the cells once they’re outside. But this team led by scientists at Ecole Polytechnique Fédérale de Lausanne drew on a new type of structure in the solar cell to create one the university says is ultra-stable. Related: Austrian scientists create a cheap, flexible solar cell just 3 micrometers thick They designed a hybrid 2D/3D perovskite solar cell. According to ScienceAlert, the 2D perovskite serves as a protective window to guard against moisture, so the 3D perovskite can generate electricity . The solar cells were built up layer by layer – like a sandwich, according to ScienceAlert – by putting different ingredients atop one another. The team built 10 by 10 centimeters squared solar panels , with what the university described as a fully printable industrial-scale process. The hybrid 2D/3D perovskite solar cells are resistant to oxygen and water, while still able to transport electrical charges. They absorb light from the whole visible spectrum, according to the university. The efficiency isn’t great yet – just 11.2 percent. But the university noted that efficiency was constant for over 10,000 hours, with zero loss in performance. Project leader Mohammad Khaja Nazeeruddin told ScienceAlert, “The important finding in this manuscript is identifying the presence of multi-dimensional 2D/3D interface. We believe [this] will trigger many further studies…widening the prospects for perovskite photovoltaics .” The journal Nature Communications published the advance online the beginning of this month.

Comments Off on Gargantuan lace sea urchins light up the night along Singapore’s marina

A swarm of gigantic, glowing sea urchins recently appeared on Singapore’s waterfront for the iLight Marina Bay Festival. Choi+Shine Architects constructed the larger-than-life creatures as “lacy rooms” that invite visitors to walk inside and enjoy their intricate structure and visual effects. The structures are inspired by sea urchin shells, which are elnclosed yet lightweight and porous. The architects recreated the intricate patterns of urchins using white double-braided polyester chord woven in 20 segments and attached to a metal frame. It took 50 people to assemble the structures by hand over a period of two months. Related: Robots helped build and sew together this amazing sea urchin-inspired pavilion Each sea urchin measures 56 feet in size and weighs around 220 pounds. The lacy pavilions are illuminated by white spot lights, creating the illusion that they glow in the dark. The calming effect and simplicity of the installation visually contrasts Singapore’s skyscrapers and celebrates the city’s cultural diversity. + Choi+Shine Architects Photos © 2016, 2017 Choi+Shine Architects

Comments Off on At least 60 dead in Ethiopian garbage "landslide"

At least 60 people are dead after a mountain of trash collapsed at a dump in Ethiopia on Saturday night. The “landslide” at Koshe Garbage Landfill, which lies just outside the country’s capital of Addis Ababa, claimed mostly women and children, according to officials . With dozens still reportedly still missing, the final death toll could be even higher, they added. Around 150 people were present when the landslide occurred, a resident told the Associated Press . Several makeshift houses, inhabited by some of the landfill’s permanent residents, are now submerged under tons of refuse. Many of those who live at the 50-year-old landfill are scavengers who sort through the dross for items to sell. Others are there because it’s all they can afford. “My mother and three of my sisters were there when the landslide happened. Now I don’t know the fate of all of them.” Tebeju Asres, who lived at the site, told AP. Koshe, which means “dirty” in the local Amharic language, has experienced smaller collapses that killed two or three people, but nothing on this scale. Related: Ethiopia announces plans to build massive 1000MW geothermal power plant About 300,000 tons of waste from the capital’s 4 million people are deposited every year at Koshe, officials say. The city has been working to turn the garbage into a source of clean energy since 2013, when it began construction on what will be Africa’s first waste-to-energy plant when completed. The Koshe waste-to-energy center, which has $120 million invested in it, is expected to generate 50 megawatts of electricity. “In the long run, we will conduct a resettling program to relocate people who live in and around the landfill,” Diriba Kuma, mayor of Addis Ababa, told AP.

Comments Off on Rogue NASA Twitter account strikes back at Donald Trump

Yet another “rogue” Twitter account has cropped up in response to Donald Trump’s efforts to muzzle government agencies: this time, Rogue NASA is taking to social media to spread climate science. The new, unofficial account is one of a number of accounts purporting to be run by national park employees in their off hours. While the account makes clear in its bio that it’s not run by government employees, its mission is clear: to spread information about climate change in the event that Trump orders the agency to go silent.
