1+ day, 3+ hour ago   (1157+ words) Quantum computers face a race against time every time they perform a calculation. Their quantum states are so fragile that even tiny disturbances from electrical noise, heating, radiation or imperfect hardware can push a computation away from its intended result....

1+ day, 5+ hour ago   (1012+ words) Around the SKA telescope, old star stories survive through practical knowledge, new meanings and changing community traditions. (CREDIT: Shutterstock) Long before enormous radio dishes began rising from South Africa’s Karoo, people there were already watching the sky. They used celestial…...

2+ day, 23+ hour ago   (1364+ words) WashU Medicine researchers found that laser brain tumor therapy outcomes improve when tumors are smaller and more fully treated. (CREDIT: Shutterstock) For many people facing glioblastoma, every treatment choice carries fear and urgency. This aggressive brain cancer often brings open-skull…...

3+ day, 3+ hour ago   (828+ words) Electronic voting promises convenience, speed and easier participation, but it carries a fundamental problem: someone or something normally has to be trusted with the ballots. Two independent physics experiments have now demonstrated another possibility. Instead of trusting a central server…...

Floating is not usually on that list. Australian engineers have now created a 3D-printed titanium structure…...

(CREDIT: Shutterstock) Humanity's first spacecraft deliberately aimed at another star may not need exotic engines, giant lasers or anything approaching the speed of…...

1+ week, 23+ hour ago   (1056+ words) A biodegradable nanomaterial helped rats regrow substantially more bone by activating repair signals already present in the body. (CREDIT: Shutterstock) A tiny engineered material may eventually offer children born with cleft lip and palate a way to rebuild missing jawbone…...

1+ week, 1+ day ago   (915+ words) Researchers observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole. (CREDIT: Dan Wilkins) A black hole nearly 800 million light-years away briefly revealed something that should ordinarily have been hidden from view. The discovery, published…...

1+ week, 3+ day ago   (741+ words) A quantum computer can do more than calculate an answer. It can also become a laboratory for reading the behavior of quantum systems that are difficult to probe with conventional methods. The work was led on the theoretical side by…...

1+ week, 6+ day ago   (1355+ words) Drops can become electrically charged as they slide across surfaces. If they then fall onto a coating—such as on a car—the coating can be corroded by the drop’s electrical discharge and permanently damaged. (CREDIT: Katharina Maisenbacher / MPI-P) A…...
