Quantum bits, or -qubits, can hold quantum information much longer now thanks to efforts by an international research team. The researchers have increased the retention time, or coherence time, to 10 milliseconds – 10,000 times longer than the previous record – by combining the orbital motion and spinning inside an atom...

Researchers suggest a novel process to explain the collision of a large black hole and a much smaller one. A lopsided merger of two black holes may have an oddball origin story, according to a new study by researchers at MIT and elsewhere.

The merger was first detected on April 12, 2019 as a gravitational wave that arrived at the detectors of both LIGO (the Laser Interferometer Gravitational-wave Observatory), and its Italian counterpart, Virgo. Scientists labeled the signal as GW190412 and determined that it emanated from a clash between two David-and-Goliath black holes, one three times more massive than the other. The signal marked the first detection of a merger between two black holes of very different sizes.

Now the new study, published today in the journal Physical Review...

Babies born with higher levels of cadmium in their umbilical cord blood may be more likely to develop childhood asthma and allergies, according to research presented at the European Respiratory Society International Congress.

Cadmium is known to be hazardous to human health and its use is restricted in the European Union, but it has been widely used, for example in batteries, pigments and as a coating for other metals. It is also present in tobacco and can enter the body via smoking or passive smoking.

Researchers say their findings lend support for tight controls over the use and disposal of cadmium.

The research was presented to the virtual conference by Professor Isabella Annesi-Maesano, research director at France’s Institut national de la santé et de la recherche médical...

Button pressing and solar energy power the retro gaming device. Researchers develop first-ever battery-free, energy-harvesting, interactive device. And it looks and feels like a retro 8-bit Nintendo Game Boy. It’s a powerful proof-of-concept, developed by researchers at Northwestern University and the Delft University of Technology (TU Delft) in the Netherlands, that pushes the boundaries of battery-free intermittent computing into the realm of fun and interaction.

Instead of batteries, which are costly, environmentally hazardous and ultimately end up in landfills, this device harvests energy from...
