Modern robots know how to sense their environment and respond to language, but what they don't know is often more important than what they do know. Teaching robots to ask for help is key to making them safer and more efficient.

Blood tests are a common, yet often painful, step in health care. But what if we could skip the needles altogether? Saliva and blood contain many of the same biomarkers, and collecting spit is as simple as drooling into a container. Researchers reporting

Noise on the radio when reception is poor is a typical example of how fluctuations mask a physical signal. In fact, such interference or noise occurs in every physical measurement in addition to the actual signal. "Even in the loneliest place in the univ

Formaldehyde can inhibit enzymes that produce hydrogen particularly efficiently. Researchers from Bochum have discovered how this can be prevented.

Researchers have developed an AI model that can predict where a drug molecule can be chemically altered.

A new study estimates that the mortality burden attributable to air pollution from fossil fuel use is considerably higher than most previous estimates -- a phaseout of fossil fuels would have tremendous, positive health outcomes.

Many people are familiar with the haunting images of wildlife -- including sea turtles, dolphins and seals -- tangled in abandoned fishing nets.

To ensure that vaccines provide strong and lasting immunization, it is often necessary to supplement the actual vaccine (antigen) with additives that stimulate the immune system: adjuvants. Today, only a few substances have been approved for use as adjuva

Autonomous vehicles hold the promise of tackling traffic congestion, enhancing traffic flow through vehicle-to-vehicle communication, and revolutionizing the travel experience by offering comfortable and safe journeys. Additionally, integrating autonomous

Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat

University of Massachusetts Amherst civil and environmental engineers have determined the factors that may help identify the schools and daycare centers at greatest risk for elevated levels of lead in drinking water. The most telling characteristic for sc

It's a story that's become all too familiar -- high winds knock out a power line, and a community can go without power for hours to days, an inconvenience at best and a dangerous situation at worst. UC Santa Cruz Assistant Professor of Electrical and Co
