X-rays advance understanding of Earth’s core-mantle boundary and super-Earth magma oceans

Posted by in category: space

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have revealed new details about Earth’s core-mantle boundary and similar regions found in exoplanets.

Traces of antimatter in cosmic rays reopen the search for ‘WIMPs’ as dark matter

Posted by in category: cosmology

One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is.

Mercury’s magnetic landscape mapped in 30 minutes

Posted by in category: space

As BepiColombo sped past Mercury during its June 2023 flyby, it encountered a variety of features in the tiny planet’s magnetic field. These measurements provide a tantalizing taste of the mysteries that the mission is set to investigate when it arrives in orbit around the solar system’s innermost planet.

3D anatomy of the Cretaceous–Paleogene age Nadir Crater

Posted by in category: futurism

A 9.2 km diameter rim, concentric normal faults and an extended damage zone are observed in 3-dimensional seismic reflection data from the Nadir crater offshore Western Africa and provide strong evidence for an impact origin.

People infer the past better than the future, study finds

Posted by in category: futurism

If you started watching a movie from the middle without knowing its plot, you’d likely be better at inferring what had happened earlier than predicting what will happen next, according to a new Dartmouth-led study published in Nature Communications.

New microchip captures exosomes for faster, more sensitive lung cancer detection from a blood draw

Posted by in categories: biotech/medical, computing

A new way of diagnosing lung cancer with a blood draw is 10 times faster and 14 times more sensitive than earlier methods, according to University of Michigan researchers.

Hexagonal magnetic defects could lead to energy-efficient neuromorphic computing

Posted by in categories: futurism, robotics/AI

Artificial intelligence applications are experiencing a boom and expected to be mainstream technologies in the near future. However, these applications run on classic computing hardware and are extremely power-hungry.

Study suggests statistical ‘noise’ affects perceived evolutionary rates

Posted by in categories: evolution, existential risks

For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that “younger” groups of organisms, in evolutionary terms, have higher rates of speciation, extinction and body size evolution, among other differences from older ones.

Physicists achieve strong coupling of Andreev qubits via microwave resonator

Posted by in categories: computing, quantum physics

Physicists from the University of Basel have succeeded in coupling two Andreev qubits coherently over a macroscopic distance for the first time. They achieved this with the help of microwave photons generated in a narrow superconducting resonator. The results of the experiments and accompanying calculations were recently published in Nature Physics, laying the foundation for the use of coupled Andreev qubits in quantum communication and quantum computing.

Engineers create a chip-based tractor beam for biological particles

Posted by in categories: biological, computing, particle physics, tractor beam

Traditional , which trap and manipulate particles using light, usually require bulky microscope setups, but chip-based optical tweezers could offer a more compact, mass manufacturable, broadly accessible, and high-throughput solution for in biological experiments.

However, other similar integrated optical tweezers can only capture and manipulate cells that are very close to or directly on the chip surface. This contaminates the chip and can stress the cells, limiting compatibility with standard biological experiments.

Using a system called an integrated optical phased array, the MIT researchers have developed a new modality for integrated optical tweezers that enables trapping and tweezing of cells more than a hundred times further away from the chip surface.
