Electronic noses sniff out volatile organic compounds

Tracing volatile organic compounds is important for public safety and all 'smell' related issues. To this end, researchers introduce a fluid mechanics-based chamber design for an electronic nose that consistently detects VOCs at low concentrations. The strategy, which includes using a shunt-like device to control the behavior of fluid flow, is a step forward in e-nose technology development.

Researchers build bee robot that can twist

A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect...

Lessons from blockbusters to help teams adapt

Researchers argue that negative emotions -- if leveraged in the right way -- can help teams adapt. They make their case by dissecting scenes from three blockbuster movies, each of which represent a different type of team and threat.

Boost for the quantum internet

A quarter of a century ago, theoretical physicists proposed a way to transmit quantum information via quantum repeaters over long distances which would open the door to the construction of a worldwide quantum information network. Now, a new generation of researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted quantum information over...

CT scan best at predicting heart disease risk in middle age

CT scans are better at predicting a middle-aged person's risk for a heart disease, such as a heart attack, than genetics, reports a new study. Conventional measures of risk factor levels include blood pressure and cholesterol. Scientists had hoped genetics could better predict risk than conventional measure, but only when considering CT scan, half the study participants moved into the high-risk...

Artificial pancreas reduces disease management burden for people with diabetes

Researchers design a novel algorithm for controlling implanted insulin pumps that accounts for the unique characteristics of individual patients. Their model, tested using an FDA-approved diabetes computer simulation, proves intraperitoneal (within the abdominal cavity) insulin delivery is fast and closely mimics natural physiological insulin delivery. They developed a model that can account for...

Embracing AI in the world of finance

Large Language Models (LLMs) like ChatGPT are shaking up the world of finance. Morgan Stanley is testing an OpenAI-powered chatbot to assist their financial advisors. The bot, trained on the bank's own research reports, offers rapid access to their extensive proprietary knowledge base.

Researchers reveal how a nanomachine cleans up inside the cell

Have you ever put off cleaning the house or decluttering the overflowing basement? Living cells cannot afford this procrastination when it comes to clearing the decks. Tiny garbage chutes are constantly active there to capture worn-out proteins, faulty cell components, or defective organelles. These garbage chutes, called autophagosomes, pick out the discarded components before they accumulate in...
