The clock’s accuracy would be as high as one second for every 300 billion years.

A collaboration between researchers from various institutes in Germany has brought us a step closer to building the first-ever nuclear clock. In experiments carried out at the European Organization for Nuclear Research (CERN), the researchers measure the radiative decay of thorium-229 nuclear isomer, the first instance of having achieved this feat and a critical component for building nuclear clocks.

For years atomic clocks have been our standard of accuracy when it comes to clocks.

UC San Diego engineers developed the low-cost clip that enables easy and affordable monitoring in resource-poor communities.

University of California San Diego engineers have created a low-cost clip that makes use of the camera and flash on a smartphone to measure blood pressure at the user’s fingertip.

This innovative clip, which can be produced at scale for as little as 10 cents, has the potential to revolutionize routine blood pressure monitoring and make it available to people in resource-poor regions.

Computer vision specialist Landing AI has a unique calling card: Its co-founder and CEO is a tech rock star.

At Google Brain, Andrew Ng became famous for showing how deep learning could recognize cats in a sea of images with uncanny speed and accuracy. Later, he founded Coursera, where his machine learning courses have attracted nearly 5 million students.

Today, Ng is best known for his views on data-centric AI — that improving AI performance now requires more focus on datasets and less on refining neural network models. It’s a philosophy coded into Landing AI’s flagship product, LandingLens.

New York City is sinking under the weight of its massive buildings, leaving it more vulnerable to rising seas, a new study finds.

Most coastal cities are slowly sinking as the earth beneath them settles and groundwater is drained away. In some metropolises, the weight of large, concrete-and-steel skyscrapers may be hastening this slump, but experts rarely, if ever, account for the mass of large buildings in projections of future sinking.

For the new study, scientists tallied the weight of every building in New York, which they put at 842 million tons, and estimated the downward force of these structures across the city. They found that buildings are leaving a bigger imprint in areas rich in clay than in areas where sand or bedrock predominate.

Octopus mothers slam themselves against rocks and eat their own arms before their eggs hatch. Scientists have discovered what leads to the self-destruction.

Once a person is dead, their body usually starts to decay immediately, although a good embalming job can delay decay.

In a recent study published in the Open Forum Infectious Diseases, researchers assess the resistance of uropathogenic Escherichia coli (UPEC) over time in adults who received uncomplicated urinary tract infections (uUTIs) outpatient care.
