Computer Scientists Establish the Best Way to Traverse a Graph

Posted by in categories: computing, information science

A new proof shows that an upgraded version of the 70-year-old Dijkstra’s algorithm reigns supreme: It finds the most efficient pathways through any graph.

It doesn’t just tell you the fastest route to one destination.


In an interview toward the end of his life, Dijkstra credited his algorithm’s enduring appeal in part to its unusual origin story. “Without pencil and paper you are almost forced to avoid all avoidable complexities,” he said.

Scientists discover a promising way to create new superheavy elements

Posted by in category: particle physics

What is the heaviest element in the universe? Are there infinitely many elements? Where and how could superheavy elements be created naturally?

The heaviest abundant element known to exist is uranium, with 92 protons (the atomic number “Z”). But scientists have succeeded in synthesizing up to oganesson, with a Z of 118. Immediately before it are livermorium, with 116 protons and tennessine, which has 117.

All have short half-lives—the amount of time for half of an assembly of the element’s atoms to decay—usually less than a second and some as short as a microsecond. Creating and detecting such elements is not easy and requires powerful particle accelerators and elaborate measurements.

Cannabidiol for musculoskeletal regenerative medicine

Posted by in categories: biotech/medical, chemistry, life extension

It is well-established that chronic MSK pain is the key factor for physical disability in the adult population. 19 The World Health Organization (WHO) estimates that 20–33% (over 1.71 billion individuals) of the global population suffers from chronic MSK pain. 20 This type of disorder is characterized by acute or chronic pain in MSK structures, which involve muscles, tendons, ligaments, bones, and nerves. 21 The most common conditions responsible for visits to a physician’s office are OA, rheumatoid arthritis, myofascial pain syndrome (MPS), and low back and neck pain. 22 Less common incidents are generally accompanying with injuries like of tendon sprains, ligament tears, muscle tears, fractures, and similar damage during sports. 20

If left untreated, these conditions progressively increase suffering, disability, and drug consumption, which subsequently diminish an individual’s quality of life. 23 This also translates to a main community health problem due to significant high expenses for health-care systems and insurance for disability. Advanced age may remain the top variable associated with the increased risk of musculoskeletal disorders (MSDs) and MSK pain; however, these conditions may still unfold at any given age for various reasons. Therefore, every individual is at risk of experiencing MSK pain throughout an entire lifetime. 24 Acute pain can become chronic due to numerous factors. The level of intensity, site, and time of noxious stimuli are dictated by the interplay between mechanical, chemical, and thermal receptors and immune cells. 25 Under standard conditions, noxious stimuli and painful sensations gradually decrease with the progression of healing.

Goldman Sachs-backed developer Gridstor builds 440MWh Texas BESS project

Posted by in category: energy

Gridstor, a US-based developer and operator of grid-scale battery storage systems, has kicked off construction of its first project in the Texas ERCOT market.

The developer said last week (17 October) that construction is underway on the Hidden Lakes Reliability Project 220MW/440MWh standalone battery energy storage system (BESS) in Texas’ Galveston County.

FAA creates America’s first new aircraft category since the 1940s

Posted by in categories: drones, energy

In a major jump into the era of eVTOL air taxis and multicopter cargo drones, the US FAA has issued new regulations that introduce the first new aircraft category, called “power-lift” aircraft, since modern helicopters were introduced in the 1940s.

According to the FAA and the International Civil Aviation Organization (ICAO), a power-lift aircraft is “a heavier-than-air aircraft capable of vertical take-off, vertical landing, and low-speed flight, which depends principally on engine-driven lift devices or engine thrust for the lift during these flight regimes and on non-rotating aerofoils for lift during horizontal flight.”

Essentially, this means aircraft that combine the characteristics of both fixed-wing planes and helicopters. In other words, they can take off, hover, and land like helicopters, yet act like fixed-winged craft in horizontal flight. As of now, these include convertiplanes, tilt-rotors, tilt-wings, rotor-wings, tail-sitters, and VSTOL aircraft like the Harrier and the F-35B Lighting II that use vector thrust, lift jets, or lift fans for vertical flight.

Thunderstorms Get Wilder: New Gamma-Ray Phenomena Discovered Above the Clouds

Posted by in category: climatology

Recent findings indicate that gamma-ray emissions from thunderstorms are far more complex and dynamic than previously understood, thanks to observations of new phenomena like Flickering Gamma-Ray Flashes (FGFs).

These flashes, alongside in-depth studies on tropical thundercloud emissions, suggest that our understanding of atmospheric electricity is evolving. This is supported by extensive fieldwork during the ALOFT campaign, which gathered unprecedented data over the Gulf of Mexico and surrounding areas.

Unlocking the 3D Spin Secrets of Magnetic Skyrmions To Power Future Electronics

Posted by in categories: computing, nanotechnology

Researchers at Berkeley Lab have advanced the understanding of magnetic skyrmions by developing techniques to image their 3D structures.

These nanoscale objects show promise for revolutionizing microelectronics through enhanced data storage capabilities and reduced energy consumption.

A difficult-to-describe nanoscale structure called the magnetic skyrmion holds potential for creating advanced microelectronic devices, including those with vast data storage capacities and significantly lower power requirements.
