FuseBot is a new robotic system that fuses visual information and radio-frequency signals to efficiently find hidden items buried under a pile of objects, whether or not the targeted item has an RFID tag.

For humans, finding a lost wallet buried under a pile of items is pretty straightforward — we simply remove things from the pile until we find the wallet...

To solve a long-standing puzzle about how long a neutron can “live” outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment at the Department of Energy’s Oak Ridge National Laboratory to try to detect a particle that has been speculated but not spotted...

Many who experience what is now called “long COVID” report feeling brain fog, breathless, fatigued and limited in doing everyday things, often lasting weeks and months post-infection. Using functional MRI with inhaled xenon gas, researchers have now identified for the first time that these debilitating symptoms are related to microscopic abnormalities that affect how oxygen is exchanged from the lungs to the red blood cells.

The LIVECOVIDFREE study, based at five centers across Ontario, and led by Western Universi...

The invention of the transistor by Bell Laboratory in 1947 ushered in an era of electronic devices that were smaller and ran cooler using far less power than their bulky and fragile vacuum tube counterparts. Transistors function as a binary switch to facilitate electrical current from off to on states. Radios, calculators and telephones were among the first wave of instruments to replace vacuum tubes with the new semiconductor technology...
