DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are faster and smaller than today's silicon-based versions. As a step toward that goal, researchers report a fast, sequential DNA computing method that is also rewritable -- just like current computers.

Street art takes many forms, and the vibrant murals on the Berlin Wall both before and after its fall are expressions of people's opinions. But there was often secrecy around the processes for creating the paintings, which makes them hard to preserve. Now, researchers have uncovered information about this historic site from paint chips by combining a handheld detector and artificial intelligence (AI) data analysis.

With dual lasers, researchers have accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a 'frame-by-frame' look at how a petawatt laser interacts with a long plasma channel, knowledge that's crucial for building future compact particle accelerators.

Researchers have pioneered a new technique called X-ray linear dichroic orientation tomography, which probes the orientation of a material's building blocks at the nanoscale in three-dimensions. First applied to study a polycrystalline catalyst, the technique allows the visualization of crystal grains, grain boundaries and defects -- key factors determining catalyst performance. Beyond catalysis, the technique allows previously inaccessible insights into the structure of diverse functional materials, including those used in information technology, energy storage and biomedical applications.

A new class of magnetism called altermagnetism has been imaged for the first time in a new study. The findings could lead to the development of new magnetic memory devices with the potential to increase operation speeds of up to a thousand times.

They were loved by Charles Darwin, they build brilliantly bad nests and they even produce a kind of “milk”. Surely, these facts are more than enough to foster a love for the urban pigeon

Rather than getting its water from impacts, our planet may have drawn in water vapour after the sun boiled it off early icy asteroids

The unusual properties of gallium have helped scientists to create delicate moulds that can be used to grow cultures of human cells resembling tiny blood vessels

Hope for a much-needed treatment for the common pregnancy complication pre-eclampsia has been raised by a successful test of an mRNA therapy in mice

From the first private moon landing to the first civilian spacewalk, Elon Musk’s SpaceX helped drive a big year for private space flight
