[ad_1] While the platform could be better than nothing, a 90 percent accuracy rate still leaves room for asymptomatic individuals to slip through the cracks. If 1,000 people use the system, 100 people may still get inaccurate results. So while this shows promise and it could indicate the kinds of solutions we’ll have in the […]

Fitbit’s in-app study will determine if wearables can detect COVID-19
[ad_1] Fitbit is venturing beyond its research partnerships to launch an infectious disease study of its own that’s very easy to join. The device maker has introduced a study inside its app that will help determine if smartwatches and fitness trackers can spot early signs of COVID-19, the flu and similar diseases without waiting for […]
Lettuce grown on the ISS is as nutritious as Earth harvests, scientists find
[ad_1] The main difference between the two is that the ISS vegetables have more microorganisms, but that’s probably just because of the microflora that live on the space station. None of them, however, are harmful to humans, such as E. coli and Salmonella. The scientists’ findings are significant, because they tell us that we can […]
YouTube’s tweaks to recommend fewer conspiracy videos seem to be working
[ad_1] The team trained its computers by having them analyze hundreds of conspiracy and non-conspiracy videos, helping them “learn” how to differentiate between the two. Once they were trained, the computers analyzed eight million recommended videos over the course of one year. Unfortunately, they were unable to classify the videos by actually watching them — […]
CDC: Vitamin E acetate is ‘closely associated’ with vaping lung injuries
[ad_1] A new clinical study analyzed samples from 51 EVALI patients and a comparison group of 99 healthy individuals. The study identified vitamin E acetate in bronchoalveolar lavage (BAL) fluid from 48 of the 51 EVALI patients. It did not detect the chemical in BAL fluid from healthy individuals. This isn’t entirely surprising. Last month, […]
Researchers create bone-inspired 3D-printed building materials
[ad_1] “Bone is a building,” says Purdue University professor Pablo Zavattieri. “It has these columns that carry most of the load and beams connecting the columns. We can learn from these materials to create more robust 3D-printed materials for buildings and other structures.” The researchers discovered that the “beams” in bones provide more stiffness and […]
Americans believe social networks make the news worse
[ad_1] About 88 percent of those in the study said that social networks favored news outlets with “attention-grabbing articles” — that is, sensationalist fare. Roughly 84 percent said companies liked sites that had many social followers, while 79 percent thought the companies favored news with a specific political stance. There were also gripes about bias, […]
Researchers are using drones to study the Amazon rainforest’s health
[ad_1] Every plant emits a different volatile organic compound (VOC) signature, or fingerprint, which can change based on factors like drought or flood. By monitoring these signals, scientists can study how forest ecosystems adapt to stressors. Despite that valuable info, the Amazon’s VOCs were previously monitored by just a handful of towers built in one […]
Scientists used phone accelerometer data to predict personality traits
[ad_1] In a paper published by the IEEE Computer Society, the researchers say how quickly, how far and when we walk — and if we pick up our phones during the night — reveals telling patterns. By correlating physical activity to personality traits, the team determined that “agreeable” people have random activity patterns and are […]
Drivers may overestimate Tesla Autopilot because of its name, study suggests
[ad_1] IIHS asked 2,000 drivers to answer questions about Autopilot (Tesla), Traffic Jam Assist (Audi and Acura), Super Cruise (Cadillac), Driving Assistant Plus (BMW) and ProPilot Assist (Nissan). They found that 48 percent of the participants thought it would be fine to take their hands off the wheel in a Tesla, whereas only 33 percent […]
