A feasibility study proposes that the laser and telescope technology on earth could be used as a beacon to attract the attention of aliens. One needs to direct 1- to 2-megawatt laser through a 30- to 45-meter telescope into space. The same laser...
DARPA wants to uncover complex events found in the digital world. Their plan is to create a semi-automated system that can detect and draw correlations between billions of events currently happening all over the world. Artificial intelligence (AI)...
A poet tries to represent the laws of a topological quantum computer through poetry. The poem translates the quantum physics in both its visual structure and word choices. Poetry is a nuanced form in which language is used for its aesthetic...
A new system based on transient grating spectroscopy detects radiation-induced changes to materials in real-time. Compared to existing techniques that take half a year to completely characterize a given material, it only takes a day. High radiation...
Researchers build a new system that can solve a quintessential discrete optimization problem, called MaxSAT. This analog solver performs better than digital computers, and can be extended to other optimization problems as well. Today’s...
Quantum computers are not supposed to check your emails, update status, or do normal software/hardware tasks. Instead, they are based on something more complex – Quantum Mechanics. Quantum computer deals with particle much smaller than the...
Researchers develop a new optical cable that can transmit data at the rate of one petabit (1000 terabits) per second. The fiber is as fine as a human hair and less prone to damage. Fiber optic cables have revolutionized the network communication...
To make things secure, it necessary to adapt truly random encryption keys that can’t be reverse-engineered. Researchers use human T cells to create encryption keys. These keys posses maximum entropy and make it impossible to breach the...
A startup named ClimaCell uses wireless networks to track and predict the weather. It can track weather in every 500-meter patch of the Earth’s surface, and update data every minute. It’s far accurate than radar and satellite weather...
New passive cooling system provides effective cooling in hot environments without using any fuel-produced power. In dry environments, it can provide cooling of up to 40°C below the ambient temperature. It could supplement existing cooling systems...
Imagine charging your laptop and phone only twice a month. Batteries based on negatively charge ion of fluorine can make this possible. For the first time, researchers have made a rechargeable fluoride-based battery that properly works at room...
MIT researchers use deep neural networks to reveal invisible objects in complete darkness. It can image biological cells and tissue without exposing them to harmful rays and intense light. Most imaging systems only yield distorted or partial data...
