Hyperloop Transportation Technologies wants to make it possible to travel from Cleveland to Chicago in less than 30 minutes. Now, it has permission from state officials to move forward with a feasibility study.
Everyone’s favorite wonder-material has moved beyond the boundaries of gravity in its latest round of testing. The material was brought aboard a parabolic flight, where a plane alternated climbing and diving in a regular rhythm to simulate micro-gravity for brief intervals of about 23 seconds at a time. These flights are often affectionately referred to as the “vomit comet,” as they tend to inspire some queasiness in humans. The graphene aboard, however, endured the environment and performed well.
Physicists from Brigham Young Univeristy may have just created the best technology for projecting 3D images, but they're not calling these images a hologram. It's still in its earliest stages, but once perfected, its applications could be varied.
Infrastructure supports and facilitates our daily lives – think of the roads we drive on, the bridges and tunnels that help transport people and freight, the office buildings where we work and the dams that provide the water we drink. But it’s no secret that American infrastructure is aging and in desperate need of rehabilitation.
What if you could run your air conditioner not on conventional electricity, but on the sun’s heat during a warm summer’s day? With advancements in thermoelectric technology, this sustainable solution might one day become a reality.
Physicists have demonstrated accelerating light beams on flat surfaces, where acceleration has caused the beams to follow curved trajectories. However, a new experiment has pushed the boundaries of what’s possible to demonstrate in a lab. For the first time in an expeirment, physicists have demonstrated an accelerating light beam in curved space. Instead of traveling along a geodesic trajectory (the shortest path on a curved surface) it bends away from this trajectory due to the acceleration.
The science and tech world has been abuzz about quantum computers for years, but the devices are not yet affecting our daily lives. Quantum systems could seamlessly encrypt data, help us make sense of the huge amount of data we’ve already collected, and solve complex problems that even the most powerful supercomputers cannot – such as medical diagnostics and weather prediction.
Between 2005 and 2017, the number of people who are digitally connected increased by a factor of three and a half. In other words, the number of people with internet access went from just over 1 billion to about 3.5, from about 15% to roughly half the world’s population. And in the coming decade, it is estimated that roughly 5 billion people – that’s 70% of the world’s population – will have internet access.
Governments are extremely worried about cryptocurrencies such as bitcoin. These virtual currencies mean you can make payments without involving the banks that most economies and government financial models are built on. People can transfer large amounts of money without the authorities knowing, potentially making it easier to evade tax or launder money.
Everything dies. To many, this seems to be the one absolute truth to the universe: Plants and animals rot and decay, stars explode and grow dark, planets crumble or are burned, and even black holes may radiate away. Indeed, our very atoms, which are the same atoms that make up everything else in the universe, decay into lighter elements as time marches on.
Overcoming a series of setbacks, an international project to build what could be a revolutionary nuclear fusion reactor, which will produce renewable energy, has reached a major milestone. Half of the infrastructure required for the International Thermonuclear Experimental Reactor (ITER) project has now been completed — seven years after construction officially began in 2010.
Researchers have discovered how to identify smartphones by examining just one photo taken by the device.The advancement opens the possibility of using smartphones—instead of FaceID or other biometrics—as a form of identification to deter cybercrime.
One of the underlying principles of quantum theory is that quantum objects can exist as waves or particles. But, they do not exist as either until they are measured, making it seemingly unachievable to identify or track quantum objects when they’re not being observed. But recently, physicists faced this issue and proved that it is not an impossibility to track unobserved quantum particles.
The soaring value of bitcoin is encouraging more and more companies and individuals to engage in “mining”. Mining is actually a process which secures the distributed bitcoin network, and processes all of its transactions.
Nothing comes for free, especially online. Websites and apps that don’t charge you for their services are often collecting your data or bombarding you with advertising. Now some sites have found a new way to make money from you: using your computer to generate virtual currencies.
The media tends to depict bullet-proof armor as something that’s thick and heavier than regular clothes. Despite being for bodily protection, the added bulk of that armor might restrict a person’s movements. But scientists at the City University of New York’s Advanced Science Research Center (ASRC) have found that diamond-hard armor doesn’t need to be thick. The key to less-bulky protection is graphene, a tightly-packed layer of bonded carbon atoms one million times thinner than a piece of paper.
Despite many varied and valiant attempts, fusion energy has remained out of reach. One new technique uses hydrogen-boron reactions to theoretically achieve fusion in a way that produces no radioactive waste.
Forget about today’s modest incremental advances in artificial intelligence, such as the increasing abilities of cars to drive themselves. Waiting in the wings might be a groundbreaking development: a machine that is aware of itself and its surroundings, and that could take in and process massive amounts of data in real time. It could be sent on dangerous missions, into space or combat. In addition to driving people around, it might be able to cook, clean, do laundry – and even keep humans company when other people aren’t nearby
A major difficulty in electric vehicle adoption is their battery capacity and range. One new study could help us potentially triple electric car range, hopefully supporting the global break from fossil fuels
The first ever all-electric cargo ship is in operation in China's Pearl River. While it's a step in the right direction to eliminate fossil fuels, the ship is being used to carry coal — the very material that encouraged the shift to clean energy.
