Vaccines against smallpox given until the mid-1970s offer continuing cross-reactive immunity to mpox (previously known as monkeypox), researchers report.
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.
A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
We are quite good at spotting unexpected objects while focused on another activity if they are moving fast, reveals a new study. The findings cast doubt on a long-standing view that our ability to see the unexpected is necessarily impaired when our attention is already directed elsewhere.
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...
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.
A new review of research suggests that the nature-based technology biochar -- a carbon-rich material -- could be an important tool to use in agriculture to help mitigate climate change.
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...
Research has shown that social media users are likely to share posts that contain information that they feel is relevant to themselves or to the people they know.
Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
Scientists working in the lab have produced a signature nuclear reaction that occurs on the surface of a neutron star gobbling mass from a companion star. Their achievement improves understanding of stellar processes generating diverse nuclear isotopes.
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...
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...

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.
A team of researchers, including Prof Jörg Kudla from the Institute of the Biology and Biotechnology of Plants at Münster University, has found a mechanism in thale cress (Arabidopsis thaliana) that enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
The soft, solid-like properties of colloidal gels are essential in fields such as food and medical applications, but how these properties manifest themselves is a long-standing mystery. Until now, it was believed that the solid nature of gels emerges through glass formation.
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...
