Rasmus Kyng has written the near-perfect algorithm. It computes the maximum transport flow at minimum cost for any kind of network – be it rail, road or electricity – at a speed that is, mathematically speaking, impossible to beat.
In recent years there has been a noticeable uptick in publicized incidents of turbulence affecting commercial aircraft. These events, sometimes unexpected and severe, have led to passenger injuries, emergency landings, and a recent rare fatality. Turbulence can be caused by a variety of factors, from the mixing of air…
The Rhisotope Project at Wits is entering a new testing phase with the insertion of radioisotopes into 20 live rhinoceros.
EPFL researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications such as noninvasive targeted drug delivery.
Today across midday peaks on the summer solstice, the world will generate about a fifth of its electricity from solar. This milestone highlights the rapid growth and impact of solar power, which has seen unprecedented expansion in recent years.
Ende 2019 begann die zuvor unauffällige Galaxie SDSS1335+0728 plötzlich heller zu leuchten als je zuvor. Um den Ursachen auf den Grund zu gehen, haben Astronom*innen Daten von mehreren weltraumbasierten und bodengebundenen Observatorien, darunter das Very Large Telescope (VLT) der Europäischen Südsternwarte (ESO)…
Every 60 seconds the equivalent of a lorry-load of plastic enters the global ocean. Where it goes after that remains largely unknown. But a new ESA Discovery study reported in Nature Communications has proven the concept of monitoring floating plastic litter using satellites.
Each of us individually is the accumulated product of thousands of generations that have come before us in an unbroken line. Our culture and technology today are also the result of thousands of years of accumulated and remixed cultural knowledge.
A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers from, among others, NIOZ published their results in the scientific journal Science of the Total Environment. They expect that many more plastic degrading fungi are living in…
Mark Hamilton, an MIT PhD student in electrical engineering and computer science and affiliate of MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), wants to use machines to understand how animals communicate. To do that, he set out first to create a system that can learn human language “from…
MIT Media Lab Spin-off Augmental has developed the MouthPad, a device that allows users to interact with phones and computers using their tongue and other head gestures.

COLLEGE PARK, Md. – In a head-to-head comparison of masks worn by people with active COVID-19, the inexpensive “duckbill” N95 came out on top, stopping 98% of COVID-19 particles in the breath of infected people from escaping into the air. Led by researchers from the University of Maryland School of Public Health…
Caltech mourns the loss of Edward C. Stone, leader of humanity’s first foray into interstellar space.
During hundreds of sessions, a significant topic went missing: scholarly research on one of Corteva’s products – neonicotinoids.
A new trial conducted by the University of Oxford reveals that sildenafil, commonly known as Viagra, enhances blood flow to the brain and improves the function of brain blood vessels in patients at a heightened risk of vascular dementia.
Swinging for the fencesThe term “particle accelerator” might lead most people to envision long underground tunnels stretching tens of kilometers and rooms full…
Researchers Found Even Lower-Performing Masks Were Protective
Members of the public have little trouble in learning very quickly how to use a third thumb – a controllable, prosthetic extra thumb – to pick up and manipulate objects.
Our data-centric way of seeing the world isn't serving us well. Barath Raghavan and Bruce Schneier argue that we need new socio-technical systems that leave room for the inherent messiness of reality.
Researchers at the Del Monte Institute for Neuroscience at the University of Rochester have identified mechanisms in the brain’s hippocampal network that are rescued by ketones. These findings build on previous research showing that ketones can alleviate neurological and cognitive affects.

Lund University. Our knowledge regarding the long-term health effects of tattoos is currently poor, and there is not a lot of research within this area. Now a research group at Lund University has investigated the association between tattoos and lymphoma.
Researchers from the University of Cambridge have developed a method to produce very low emission concrete at scale – an innovation that could be transformative in the transition to net zero.
The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
We identified how millions of concepts are represented inside Claude Sonnet, the first detailed look inside a production-grade language model.
