AI system learns to model how fabrics interact by watching videos

In a paper published on the preprint server Arxiv.org, researchers at MIT CSAIL, Nvidia, the University of Washington, and the University of Toronto describe an AI system that learns the physical interactions affecting materials like fabric by watching videos. They claim it can extrapolate to interactions it hasn’t seen before, like those involving multiple shirts […]

COVID-KG uses AI to scan thousands of studies to answer doctors’ coronavirus questions

The number of studies about COVID-19 has risen steeply from the start of the pandemic, from around 20,000 in early March to over 30,000 as of late June. In an effort to help clinicians digest the vast amount of biomedical knowledge in the literature, researchers affiliated with Columbia, Brandeis, DARPA, UCLA, and UIUC developed a […]

Researchers Debate Infecting People With Coronavirus to Test Vaccines

One way to quickly see if a coronavirus vaccine works would be to immunize healthy people and then deliberately expose them to the virus, some researchers are suggesting. Proponents say this strategy, called a human challenge trial, could save time because rather than conducting tests the usual way — by waiting for vaccinated people to […]

Salesforce researchers claim new method mitigates AI models’ gender bias

Researchers at Salesforce and the University of Virginia have proposed a new way to mitigate gender bias in word embeddings, the word representations used to train AI models to summarize, translate languages, and perform other prediction tasks. The team claims that correcting for certain regularities — like word frequency in large data sets — allows […]

How We Get Stronger

When we start to lift weights, our muscles do not strengthen and change at first, but our nervous systems do, according to a fascinating new study in animals of the cellular effects of resistance training. The study, which involved monkeys performing the equivalent of multiple one-armed pull-ups, suggests that strength training is more physiologically intricate […]

In Early February, the Coronavirus Was Moving Through New York

A new study offers the first physical evidence that the coronavirus was circulating at low levels in New York City as early as the first week of February. The city confirmed its first infection on March 1. Mathematical models have predicted that the virus was making its way through the city weeks before then, but […]

Models of Social Interaction Do Not Reflect Current Social Life 

The reason is that the physical world is the most desirable of worlds because theories about normal human behavior were developed back when the internet was still a pipe dream and over a decade before social media tore apart our social fabric.  An analogy from the car industry would be measuring how much we drive […]

Most People With Coronavirus Won’t Spread It. Why Do a Few Infect Many?

At a May 30 birthday party in Texas, one man reportedly infected 18 friends and family with the coronavirus. Reading reports like these, you might think of the virus as a wildfire, instantly setting off epidemics wherever it goes. But other reports tell another story altogether. In Italy, for example, scientists looked at stored samples […]

How Do Flying Snakes Glide Through the Air? ‘It’s Hard to Believe’

Jake Socha is an expert on flying snakes who uses detailed scientific terminology such as “this big, wiggly, ribbon thing” to describe his soaring quarry. It is an apt description, but don’t be fooled. When a snake launches off a tree in its Southeast Asian habitat and lands on another tree dozens of feet away, […]

Microsoft open-sources Lumos, a Python library for automatically monitoring web app metrics

Microsoft recently open-sourced Lumos, a Python library for automatically detecting and diagnosing metric regressions in “web-scale” applications. In a technical paper, company researchers claim Lumos has been deployed in millions of sessions across the developer teams at Skype and Microsoft Teams, enabling engineers to detect hundreds of changes in metrics and reject thousands of false […]

Even the South Pole Is Warming, and Quickly, Scientists Say

The South Pole, the most isolated part of the planet, is also one of the most rapidly warming ones, scientists said Monday, with surface air temperatures rising since the 1990s at a rate that is three times faster than the global average. While the warming could be the result of natural climate change alone, the […]

Actual Coronavirus Infections Vastly Undercounted, C.D.C. Data Shows

The number of coronavirus infections in many parts of the United States is more than 10 times higher than the reported rate, according to data released on Friday by the Centers for Disease Control and Prevention. The analysis is part of a wide-ranging set of surveys started by the C.D.C. to estimate how widely the […]

How the World Missed Covid-19’s Silent Spreaders

Symptomless transmission makes the coronavirus far harder to fight. But health officials dismissed the risk for months, pushing misleading and contradictory claims in the face of mounting evidence. By Matt Apuzzo, Selam Gebrekidan and David D. Kirkpatrick June 27, 2020 MUNICH — Dr. Camilla Rothe was about to leave for dinner when the government laboratory […]

Study Suggests Coronavirus Emerged In Spain Much Earlier Than Thought

In a study not yet published in a journal, scientists have reported that the new coronavirus was present in wastewater in Barcelona, Spain in March 2019, a finding that, if confirmed, would show that the pathogen had emerged much earlier than previously thought. But independent experts who reviewed the findings said they doubted the claim. […]

How Bees Avoid Bumping Into Nature’s Obstacle Course

For a human, a breeze-ruffled garden is a peaceful scene: Dandelion seeds float, leaves rustle and flowers bob their heads. But if you’re a bee, it’s a minefield. For a small creature with delicate wings, airborne seeds, shifting leaves and lurching flowers are basically projectiles, trap doors and Godzilla-tipped skyscrapers. It’s a situation honeybees and […]

See How Dolphins Learn This Eating Trick

When hunger strikes, dolphins don’t mess around. In Shark Bay, Western Australia, these swimming mammals have devised devious tactics to snare slippery prey. In one trick, dolphins chase fish into empty seashells, then chauffeur the shells to the ocean surface, where they use their beaks to jostle the prey into their mouths. This behavior, called […]

Two Black Holes Colliding Not Enough? Make It Three

In an announcement on Thursday, astronomers described the detection of an epistemological marvel: an invisible collision of invisible objects — black holes — had become briefly visible. The story goes like this: Long, long ago, about 4 billion years before now and in a faraway galaxy, a pair of black holes collided. Typically such an […]

Google’s MixIT AI isolates speakers in audio recordings

In a paper published on the preprint server Arxiv.org, researchers at Google and the University of Illinois propose mixture invariant training (MixIT), an unsupervised approach to separating, isolating, and enhancing the voices of multiple speakers in an audio recording. This approach requires only single-channel (e.g., monaural) acoustic features, and researchers claim it “significantly” improves speech […]

Intel’s Sample Factory speeds up reinforcement learning training on a single PC

In a preprint paper this week published on Arxiv.org, researchers at Intel describe Sample Factory, a system that achieves high throughput — higher than 105 environment frames per second — in reinforcement learning experiments. In contrast to the distributed servers and hardware setups those experiments typically require, Sample Factory is optimized for single-machine settings, enabling […]
