Using nanostructures on a flat piece of glass can make lenses smaller, lighter and much cheaper – while providing better image quality.
If we keep burning fossil fuels indefinitely, global warming will eventually melt all the ice at the poles and on mountaintops, raising sea level by 216 feet. Explore what the world’s new coastlines would look like.
A 13-year-old boy and an amateur archaeologist have helped to uncover a unique stash of lost treasure thought to be associated with the legendary Danish King "Harry Bluetooth," who brought Christianity to Denmark in the 10th century.
Researchers from NVIDIA, led by Guilin Liu, introduced a state-of-the-art deep learning method that can edit images or reconstruct a corrupted image, one that has holes or is missing pixels. The method can also be used to edit images by removing content and filling in the resulting holes.
The parasite that causes malaria can change the way you smell, making you more attractive to mosquitoes, according to a new study. The work may help explain why the disease is able to spread so effectively. The new study adds important details about how human odor is influenced by malaria, says Audrey Odom John, a parasitologist at Washington University School of Medicine in St. Louis, Missouri who was not involved in the study. “This is very cool, and it’s been needed for some time.”
The theory of multiple intelligences differentiates intelligence into specific 'modalities', rather than seeing intelligence as dominated by a single general ability. Howard Gardner proposed this model in his 1983 book Frames of Mind: The Theory of Multiple Intelligences. According to the theory, an intelligence must fulfill eight criteria:
If you’re like me, you were taught as a child to never swear, or else you’d get soap in your mouth. Which I did, several times in fact throughout childhood (true story). However, despite these very unpleasant events which left a very strong taste in my mouth, the act of getting my tongue scrubbed vigorously with soap by my mother has never stopped me from engaging in healthy amount of swearing as an adult.
Tiny plastic bits contaminate bottled water sold around the world, a new study finds. For now, scientists can only guess at the source of the plastic. Whether ingesting it might pose any risk also remains unknown. Researchers tested more than 250 bottles of water. They came from nine countries and were sold under 11 different brands. These included Nestle Pure Life, Aquafina, Dasani, Evian, San Pellegrino and Gerolsteiner. Plastic turned up in 93 out of every 100 of the bottles.
Diamonds are famous for being the hardest natural material found on Earth, but that hasn’t stopped scientists from figuring out how to bend and stretch them like a piece of a rubber.
The nebula is a "raucous star nursery full of birth and destruction," NASA says.
Bizarre circular shapes spotted by a research plane in the Arctic's Beaufort Sea are puzzling NASA scientists.
Ten years ago, Amazon introduced the Kindle and established the appeal of reading on a digital device. Four years ago, Jeff Bezos and company rolled out the Echo, prompting millions of people to start talking to a computer.
For earth day, Tesla released some interesting data about its fleet of electric vehicles and its energy products with a fun Lord of the Rings theme.
The team that’s closer to winning tends to get more favorable ball and strike calls when the game goes into extras.
Machine learning algorithms pinpoint new materials 200 times faster than previously possible
Los Angeles Mayor Eric Garcetti said on Monday that he officially approved SpaceX's plan to build a Mars spaceship factory at the city's port.
Results from a long-running field experiment suggest that a major group of plants could thrive as the level of carbon dioxide in the atmosphere increases.
The English word "Earth", German "Erde", Swedish "jorden", and similar expressions in other Germanic languages come from Proto-Germanic *erþō, which meant, well, "earth". They are shown in brown
At the Space Symposium conference in Colorado Springs, Colorado, NASA outlined their plans for the Lunar Orbital Platform Gateway, a stepping stone for future missions to Mars. Test flights of the first components are planned for next year.
If you hold your breath and plunge your face into a tub of water, your body automatically triggers what's called the diving response. Your heart rate slows, your blood vessels constrict, and your spleen contracts, all reactions that help you save energy when you're low on oxygen. Most people can hold their breath underwater for a few seconds, some for a few minutes. But a group of people called the Bajau takes free diving to the extreme, staying underwater for as long as 13 minutes at depths of around 200 feet.
"There's a challenge for you — what is THAT?" Unusual deep-sea creatures seen for the first time can sometimes stump even a seasoned expert in marine biology. And in a recent video of an ocean dive in the Gulf of Mexico, an expert's off-camera exclamation revealed his surprised response to the appearance of a squid that had contorted itself into such a peculiar shape that it barely resembled a squid at all.
Advances in artificial intelligence and automation could replace as many as half the nation’s financial services workers over the next decade, industry experts say, but it’s going to take a big investment to make that happen. James D’Arezzo, CEO of Glendale-based Condusiv Technologies, says that’s where things are headed. And the process will be complicated. “Unless banks deal with the performance issues that AI will cause for ultra-large databases, they will not be able to take the money gained by eliminating positions and spend it on the new services and products they will need in order to stay competitive,” he said.
Ants have an incredible instinct to help their comrades.
On a Wednesday afternoon in a sprawling lot on a former naval air station in Alameda, California, across the bay from San Francisco, workers are welding a massive black tube together. The tube–roughly the length of a football field–is one piece of a larger system that will set sail for the Great Pacific Garbage Patch this summer, where it will begin collecting some of the 1.8 trillion pieces of plastic trash brought there by ocean currents.
A new study has shed more light on the revelations that Hans Asperger, the Austrian pediatrician for whom a form of autism is named, had collaborated with the Nazis and actively assisted in the killing of disabled children. Published on Wednesday in the journal Molecular Autism by the medical historian Herwig Czech, the report relies on eight years of research that included the examination of previously unseen Nazi-era documents.
Nasa is to make a major announcement about its project to put nuclear power in space. The agency has been working on "Kilopower" – a project to use a nuclear reactor to generate clean energy on the Moon, Mars and beyond – for some time. And now it will hold a press conference to reveal the latest results from its plans to unveil a new space exploration power system, it has said.
The Cosmosphere has started to restore the Apollo 11 mission control consoles to their original state.
A study published Wednesday in the journal Environmental Research found symptoms of Alzheimer’s disease in babies less than a year old in Mexico City—suggesting not only that the disease takes shape earlier on than previously suspected but that environmental factors may be to blame. The researchers, led by Lilian Calderón-Garcidueñas at the University of Montana, investigated the autopsies of 203 Mexico City residents between the ages of 11 months and 40 years old.
Howdy, pardner, please buckle your seatbelt and put your phone on airplane mode.
The secret behind the ability of a group of “sea nomads” in Southeast Asia to hold their breath for extraordinary periods of time while freediving to hunt fish has finally been revealed – and it’s down to evolution. The Bajau people are able to dive tens of metres underwater with no conventional diving aids. Instead they rely on weights, handmade wooden goggles – and a single breath of air.
As Techdirt has pointed out a number of times, attacking the huge free online repository of academic papers, Sci-Hub, is wrong from a number of viewpoints. It's wrong because Sci-Hub is not a site aiming to profit from the labor of others, but is...
Age discrimination can be very hard to prove.In a ProPublica feature that collected the stories of over 1,400 former IBM employees, it was estimated that a staggering 20,000 American employees ages 40 and over have been eliminated by the company. How does one of the country’s largest tech giants quietly push out this many older workers? Don’t we have laws to protect people at the end of their careers?
As the fight against "fake meat" rages on in the U.S., Silicon Valley-based Impossible Foods is expanding beyond the country. The food start-up, which manufactures a plant-based burger it calls the "Impossible Burger," is now taking its flagship product to Hong Kong. Speaking with CNBC's "Squawk Box" on Thursday, Impossible Foods CFO and COO David Lee said the company's mission is to be "everywhere," and Hong Kong was chosen as the first city for the international expansion due to its reputation as a culinary "epicenter."
Is it possible that modern humans aren't the first civilization on Earth? This is the insanely interesting question probed by "The Silurian Hypothesis", a new paper authored by Gavin A. Schmidt and Adam Frank, two NASA scientists. As they point out, if an industrialized civilization existed in the deep past, it's not clear there'd be easily recognizable traces of it. Our geologic record doesn't go back any further than the Quaternary period of about 2.6 million years ago.
MIT engineers have developed a continuous manufacturing process that produces long strips of high-quality graphene. The team’s results are the first demonstration of an industrial, scalable method for manufacturing high-quality graphene that is tailored for use in membranes that filter a variety of molecules, including salts, larger ions, proteins, or nanoparticles. Such membranes should be useful for desalination, biological separation, and other applications.
The hypothetical cosmic portals linking two points of space-time that we call wormholes are the stuff of science fiction and space theory right now – but if they really do exist, one scientist has come up with a way we might spot them: by the shado
In 1976, my final year of medical school, I travelled abroad and spent several months working in the hematology clinic at Hadassah Hospital, in Jerusalem. Every day, I attended to children and teen-agers suffering from a blood disorder called beta thalassemia. They were easy to identify in the clinic waiting room. Their skin was a pale yellow, their skull and facial bones were distorted, and their abdomens bulged from an enlarged liver and spleen. Many were short of breath, with swollen legs and other signs of heart failure.
Famous astrophysicist Neil deGrasse Tyson and Goldman Sachs share a common belief: The next trillion-dollar industry will be in the mining sector—in outer space. As Neil deGrasse Tyson puts it: "The first trillionaire there will ever be is the person who exploits the natural resources on asteroids. There's this vast universe of limitless energy and limitless resources. I look at wars fought over access to resources. That could be a thing of the past, once space becomes our backyard."
The US Senate on Wednesday cleared the way for Jim Bridenstine, a Republican Congress member from Oklahoma, to become the next administrator of NASA. The post has remained vacant since January 2017, when Charles Bolden, the space agency’s leader under President Obama, stepped down. If Bridenstine is approved in the final Senate vote expected this week, he’ll bring some odd qualifications to the job, and likely some controversy.

Cotton buds, plastic drinking straws and other single-use plastics could be banned from sale in England next year in the next phase of the campaign to try to halt the pollution of the world’s rivers and oceans. Theresa May hopes to use the announcement to encourage the Commonwealth heads of government to join the fight as the meeting opens formally on Thursday. “The Commonwealth is a unique organisation with a huge diversity of wildlife, and environments – so it is vital we act now,” the prime minister will say, urging all Commonwealth countries to participate.
That's according to a new survey of young people who said they use the devices.
It’s excusable if you didn’t notice it when a scientist named Daniel J. Buehrer, a retired professor from the National Chung Cheng University in Taiwan, published a white paper earlier this month proposing a new class of math that could lead to the birth of machine consciousness. Keeping up with all the breakthroughs in the field of AI can be exhausting, we know. Robot consciousness is a touchy subject in artificial intelligence circles. In order to have a discussion around the idea of a computer that can ‘feel’ and ‘think,’ and has it’s own motivations, you first have to find two people who actually agree on the semantics of sentience.
By making the first progress on the “chromatic number of the plane” problem in over 60 years, an anti-aging pundit has achieved mathematical immortality. By Evelyn Lamb.
