For many, fitness trackers have become indispensable tools for monitoring how many calories they’ve burned in a day. But for those living with obesity, who are known to exhibit differences in walking gait, speed, energy burned and more, these devices often inaccurately measure activity — until now. 

Scientists at Northwestern University have developed a new algorithm that enables smartwatches to more accurately monitor the calories burned by people with obesity during various physical activities.

Researchers at the University of Massachusetts Amherst have pushed forward the development of computer vision with new, silicon-based hardware that can both capture and process visual data in the analog domain. Their work, described in the journal Nature Communications, could ultimately add to large-scale, data-intensive and latency-sensitive computer vision tasks.

Researchers Mostafa Bedewy, at the University of Pittsburgh Swanson School of Engineering, and Ahmed Aziz Ezzat, at Rutgers University, have received a $549,947 collaborative National Science Foundation (NSF) grant to study new ways of controlling the formation of alumina-supported iron nanoparticles by using machine learning (ML) to efficiently model, characterize, simulate, and predict their growth. Their research seeks to advance understanding of these particles to improve nanomanufacturing.

A sweeping new analysis finds that rising global temperatures will dampen the world’s capacity to produce food from most staple crops, even after accounting for economic development and adaptation by farmers.

University at Buffalo researchers have shown that a considerable portion of a human’s roughly 20,000 genes express more like a standard light switch — fully on or fully off. 

A newly discovered, raccoon-sized armored monstersaurian from the Grand Staircase-Escalante National Monument in Southern Utah, United States, reveals a surprising diversity of large lizards at the pinnacle of the age of dinosaurs. Named for the goblin prince from J.R.R. Tolkien’s “The Hobbit,” the new species Bolg amondol also illuminates the sometimes-murky path that life traveled between ancient continents.
