Sheba Study: AI Can Spot Patients At Risk Of Pulmonary Embolism

Posted by in categories: biotech/medical, information science, robotics/AI

A newly published study by Sheba Medical Center, Israel’s largest and internationally ranked hospital, shows that AI analysis of medical records as patients are admitted to the ER can accurately identify those at high risk of pulmonary embolism (PE).

A pulmonary embolism is a sudden blockage in an artery in the lung caused by a blood clot, most commonly due to a dislodged clot in the leg. They are normally diagnosed during a CT scan.

Using machine learning, the researchers trained an algorithm to detect a pulmonary embolism before a patient was hospitalized, based on existing medical records.

Scientists observe first neutrinos with prototype detector

Posted by in category: particle physics

In a major step for the international Deep Underground Neutrino Experiment (DUNE), scientists have detected the first neutrinos using a DUNE prototype particle detector at the U.S. Department of Energy’s Fermi National Accelerator Laboratory (Fermilab).

Neutrons reveal the existence of local symmetry breaking in a Weyl semimetal

Posted by in category: materials

The first materials scientists might have been early humans who—through trial-and-error experiments—discovered the first “cutting-edge” technologies. They found that the best arrowheads and other tools could be made from certain types of natural, structural materials, which at the time included stones and animal bones.

ALICE measures interference pattern akin to the double-slit experiment

Posted by in categories: particle physics, quantum physics

In the famous double-slit experiment, an interference pattern consisting of dark and bright bands emerges when a beam of light hits two narrow slits. The same effect has also been seen with particles such as electrons and protons, demonstrating the wave nature of propagating particles in quantum mechanics.

Chaos theory approach reveals long-distance relationship in seemingly random behavior of bowhead whales

Posted by in category: futurism

Applying chaos theory to the movement of iconic arctic whales uncovered a 24-hour diving cycle and a long-range (~100 km) synchronization.

High-speed cameras reveal behavior of microplastics in turbulent water

Posted by in categories: biological, particle physics

Microplastics are a global problem: they end up in rivers and oceans, they accumulate in living organisms and disrupt entire ecosystems. How tiny particles behave in a current is difficult to describe scientifically, especially in the case of thin fibers, which make up more than half of microplastic contamination in marine life-forms. In turbulent currents, it is almost impossible to predict their movement.

An automated scheme for optical lens design looks set to enhance mobile phone cameras

Posted by in categories: computing, mobile phones, robotics/AI

An automated computational approach to the optical lens design of imaging systems promises to provide optimal solutions without human intervention, slashing the time and cost usually required. The result could be improved cameras for mobile phones with superior quality or new functionality.

Align or die: Revealing unknown mechanism essential for bacterial cell division

Posted by in category: materials

A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto “dying to align”: Misaligned filaments “die” spontaneously to form a ring structure at the center of the dividing cell. The study, led by the Šarić group at the Institute of Science and Technology Austria (ISTA), was published in Nature Physics. The work could find applications in developing synthetic self-healing materials.

Research team uses tunable laser to develop straightforward broadband spectroscopy method with Hz-level precision

Posted by in category: particle physics

Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser technology have further enhanced its capabilities. There are two main types of laser spectroscopy: frequency comb-based laser spectroscopy and tunable continuous-wave (CW) laser spectroscopy.

Newly discovered X-ray binary system contains a white dwarf, observations find

Posted by in category: space

Astronomers from the Pennsylvania State University (PSU) and elsewhere have observed an X-ray binary system known as CXOU J005245.0–722844. They detected an X-ray outburst from this binary and found that it harbors a white dwarf star. The findings were presented in a research paper published August 2 on the pre-print server arXiv.
