Researchers at universities in New York and Ningbo, China, say they have created tiny robots built from DNA that can reproduce themselves.

Such nanorobots could one day launch search-and-destroy missions against cancer cells within a human’s bloodstream without the need for surgery or collect toxic waste from the ocean.

The tiny mechanism is so small that 1,000 of them could fit into the width of a sheet of paper.

A proposed model unites quantum theory with classical gravity by assuming that states evolve in a probabilistic way, like a game of chance.

Physicists’ best theory of matter is quantum mechanics, which describes the discrete (quantized) behavior of microscopic particles via wave equations. Their best theory of gravity is general relativity, which describes the continuous (classical) motion of massive bodies via space-time curvature. These two highly successful theories appear fundamentally at odds over the nature of space-time: quantum wave equations are defined on a fixed space-time, but general relativity says that space-time is dynamic—curving in response to the distribution of matter. Most attempts to solve this tension have focused on quantizing gravity, with the two leading proposals being string theory and loop quantum gravity. But new theoretical work by Jonathan Oppenheim at University College London proposes an alternative: leave gravity as a classical theory and couple it to quantum theory through a probabilistic mechanism [1].

As demand for electric vehicles soars, scientists are searching for materials to make sustainable batteries. Lignin, from waste paper pulp, is shaping up to be a strong contender.

The mainstay material of electronics is now yielding better energy storage.

A massive hole opened up in the Sun’s atmosphere over the weekend, measuring more than 60 times the diameter of the Earth across at its peak.

Coronal holes like this one, imaged by NASA’s Solar Dynamics Observatory, occur when the Sun’s magnetic field suddenly allows a huge stream of the star’s upper atmosphere to pour out in the form of solar wind.

Over a short period of time, these highly energized particles can eventually make their way to us and — if powerful enough — wreak havoc on satellites in the Earth’s orbit. In rare instances, they can even mess with the electrical grid back on the ground.

Computing giant IBM has launched three new innovations in quantum tech – the first utility-scale quantum computer, the first 1,000+ qubit chip and the most efficient quantum processor in terms of error correction.

IBM gave a sneak preview of its Quantum System Two during a conference last year. Following 12 months of additional research and development, it has now officially launched the system, which is described as “the first modular, utility-scale quantum computer.”

Pancreatic cancer is deadly, and its toll is growing. Scientists find that scar tissue around the tumor suggests how long a patient will live after diagnosis.
