Kyoto, Japan -- Cells possess an innate immune system that defends against invasive pathogens such as bacteria and viruses. Previous studies have mapped out the cytoplasmic cGAS-STING pathway in the cytoplasm, known for responding to foreign nucleic acids, such as double-stranded DNA. Micronuclei -- or MN, abnormal intracellular structures containing the cell's DNA -- have also been suspected of triggering the pathway. However, no conclusive evidence exists of pathway activation by MN-induced cyclic GMP-AMP synthase, or cGAS. Now, Kyoto University and the AIRC Institute of Molecular Oncology, or IFOM, have ...

Winter storms that provide crucial snow and rainfall to northern India are arriving significantly later in the year compared to 70 years ago, a new study has found, exacerbating the risk of catastrophic flooding while also reducing vital water supplies for millions of Indians. The cyclonic storms, known as western disturbances, typically bring heavy snow to the Himalayas from December to March. This snowpack slowly melts in spring, providing a steady supply of irrigation water for wheat and other crops downstream. The study, published today (Tuesday, 12 March 2024), in the journal Weather and ...

UNIVERSITY PARK, Pa. — A newly developed “GPS nanoparticle” injected intravenously can home in on cancer cells to deliver a genetic punch to the protein implicated in tumor growth and spread, according to researchers from Penn State. They tested their approach in human cell lines and in mice to effectively knock down a cancer-causing gene, reporting that the technique may potentially offer a more precise and effective treatment for notoriously hard-to-treat basal-like breast cancers. They published their work today (March 11) in ACS Nano. They also filed a provisional application to patent the technology ...

Researchers have developed a new method for triggering and imaging seizures in epilepsy patients, offering physicians the ability to collect real-time data to tailor epilepsy surgery. In contrast to previous practice, where physicians from neurology and nuclear medicine had to wait for hours to days in hopes of capturing the onset of a seizure, the new method is convenient, spares resources, and is clinically feasible. This research was published in the March issue of The Journal of Nuclear Medicine. People with epilepsy and seizures who do not respond to medication are often helped by brain surgery. The goal ...

Device could help facilitate the operation of new particle colliders, such as the Electron-Ion Collider. In particle colliders that reveal the hidden secrets of the tiniest constituents of our universe, minute particles leave behind extremely faint electrical traces when they are generated in enormous collisions. Some detectors in these facilities use superconductivity — a phenomenon in which electricity is carried with zero resistance at low temperatures — to function. For scientists to more accurately observe the behavior of these particles, these weak electrical signals, or currents, need ...

In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information. In new research published in the Journal of the American Chemical Society, University of Illinois Urbana Champaign materials science & engineering professor Daniel Shoemaker and graduate student Zachary Riedel ...

BOSTON – In the largest randomized clinical trial and first of its kind to date in the United States, a team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) assessed the efficacy and safety of using a drug-coated balloon in patients undergoing coronary angioplasty. In an original investigation presented at the Cardiology Research Technology conference in Washington, D.C. and published simultaneously in JAMA, the team reports that patients treated with a balloon coated with paclitaxel, a drug to prevent restenosis, experienced lower rates of failure compared with patients treated with an uncoated balloon. The findings of the trial—which ...

Some cancerous tumors hijack proteins that act as “brakes” on our immune system and use them to form a sort of shield against immune recognition. Immunotherapy treatments have been created that turn off these “brakes” and allow our body to attack foreign-looking cancer cells. To further advance such treatments, researchers at Stanford University and New York University have published a new structure of one of these brake proteins, LAG-3. Their work contains key details of the molecule’s structure, as well as information about how the LAG-3 protein functions. Although over a dozen immunotherapies targeting LAG-3 are in development, and one is already FDA approved, ...

Scientists at The Universities of Manchester and Oxford have developed an AI framework that can identify and track new and concerning COVID-19 variants and could help with other infections in the future. The framework combines dimension reduction techniques and a new explainable clustering algorithm called CLASSIX, developed by mathematicians at The University of Manchester. This enables the quick identification of groups of viral genomes that might present a risk in the future from huge volumes of data. The study, presented this week ...

Cicadas are the soundtrack of summer, but their pee is more special than their music. Rather than sprinkling droplets, they emit jets of urine from their small frames. For years, Georgia Tech researchers have wanted to understand the cicada’s unique urination. Saad Bhamla, an assistant professor in the School of Chemical and Biochemical Engineering, and his research group hoped for an opportunity to study a cicada’s fluid excretion. However, while cicadas are easily heard, they hide in trees, making them hard to observe. As such, seeing a cicada pee is an event. Bhamla’s team had only watched the process on YouTube. Then, ...

Scientists have discovered the specific enzyme that a species of sandfly uses to produce a pheromone attractant, which could lead to the creation of targeted traps to control them and reduce the spread of the potentially fatal disease, Leishmaniasis. The team from the University of Nottingham’s School of Chemistry analysed the genome of the Lutzomyia longipalpis, a species of sandfly native to Brazil and South America that can spread a disease called Leishmaniasis.  The study identified the enzyme, called a Terpene Synthase that is responsible ...

CAMBRIDGE, MA -- MIT chemists have designed a sensor that detects tiny quantities of perfluoroalkyl and polyfluoroalkyl substances (PFAS) — chemicals found in food packaging, nonstick cookware, and many other consumer products. These compounds, also known as “forever chemicals” because they do not break down naturally, have been linked to a variety of harmful health effects, including cancer, reproductive problems, and disruption of the immune and endocrine systems. Using the new sensor technology, the researchers showed that they could detect PFAS levels as low as 200 parts per trillion in a water sample. The device they designed could offer a way ...

The perception of softness can be taken for granted, but it plays a crucial role in many actions and interactions – from judging the ripeness of an avocado to conducting a medical exam, or holding the hand of a loved one. But understanding and reproducing softness perception is challenging, because it involves so many sensory and cognitive processes. Robotics researchers have tried to address this challenge with haptic devices, but previous attempts have not distinguished between two primary elements of softness perception: cutaneous cues (sensory feedback ...
