Conveyor Jam Detector For Industries

The conveyor jam detector circuit presented here is designed to activate an alarm device or programmable logic controller (PLC) when the speed of the conveyor system falls below the set minimum speed, alerting the workers the possibility of jamming of the conveyor system. Conveyor jam detector is an indispensable sensor device found in most conveyor…

Imaging tech captures molecule ‘wobble’ in 3D

Researchers have found a way to visualize individual molecules inside living cells in greater detail, showing their position and orientation in 3D, and even how they wobble and oscillate. The work could shed invaluable insights into the biological processes involved, for example, when a cell and the proteins that regulate its functions react to the…

Fake ‘grammar’ shows apes get language basics

Humans are not the only ones that can identify rules in complex language-like constructions—monkeys and great apes can, too, according to a new study. Researchers used a series of experiments based on an “artificial grammar” to conclude that this ability can be traced back to our ancient primate ancestors. “This suggests that this crucial element…

Little bat-winged dinos could glide, but not fly

Two small dinosaurs with bat-like wings struggled to fly but could glide clumsily between trees, researchers report. Unable to compete with other tree-dwelling dinosaurs and early birds, Yi and Ambopteryx went extinct after just a few million years. The findings, published in iScience, support that dinosaurs evolved flight in several different ways before modern birds…

Heat-reflecting paint keeps things cool without AC

A new white paint can keep surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings, researchers report. The paint would absorb nearly no solar energy and send heat away from the building, replacing the need for air conditioning, according to the researchers. Without the building heating up, air conditioning wouldn’t have to kick…

AI counts 1.8 billion trees in Sahara Desert

There are far more trees in the West African Sahara Desert than you might expect, according to a study that combined artificial intelligence and detailed satellite imagery. Researchers counted over 1.8 billion trees and shrubs in the 1.3 million square kilometer (501,933 square miles) area that covers the western-most portion of the Sahara Desert, the…
