Some people with psychiatric conditions, including addiction and attention deficit hyperactivity disorder, struggle to control their urges or make decisions under uncertainty. In a collaboration between the University of Cambridge and the University of British Columbia, Tristan Hynes and colleagues used rats to explore the role of a specific reward-related neuron population in shaping impulsivity and risky decision-making during a gambling task.  As reported in their JNeurosci paper, the researchers manipulated the neuron population’s activity as rats chose between ...

Whether natural or synthetic, polymers — large molecules made up of repeating units called monomers — exhibit complex structures and properties that make them useful in a wide range of applications. In their soft, nearly liquid biogel form, polymers viewed through an optical microscope resemble a bowl of tangled soft noodles. In that state, they tend to coacervate, or combine, with other polymers — when those polymers carry opposite electrostatic charges.    UC Santa Barbara ...

Vibrant orange-coloured lichens are helping scientists discover dinosaur fossils in Canada, according to a new study published today [3 November] in Current Biology. An international team of palaeontologists and remote sensing scientists have made an exciting discovery at UNESCO World Heritage Site Dinosaur Provincial Park, in Alberta. They have found that certain lichen species preferentially colonise exposed dinosaur bones, creating distinctive spectral signatures that can be detected from 30 metres above ground using drones. Dr Brian ...

Increasing your steps by even a little bit may help slow down the progression of Alzheimer’s disease among people at heightened risk, according to a new study. In a paper published in Nature Medicine, Mass General Brigham researchers found that physical activity was associated with slower rates of cognitive decline in older adults with elevated levels of amyloid-beta, a protein associated with Alzheimer’s. Cognitive decline was delayed by three years on average for people who walked just 3,000-5,000 steps per day, and by seven years in people who walked 5,000-7,500 steps per day. Sedentary individuals had a significantly faster buildup of ...

Scientists are exploring leading-edge technologies that could transform how cancer is studied, detected and treated by catching it earlier, when it’s more treatable and survival rates are highest. A new review by researchers at Oregon Health & Science University’s Knight Cancer Institute and other universities highlights how advances in New Approach Methodologies and tissue engineering are offering powerful new tools to study the earliest stages of cancer development. New Approach Methodologies use human-relevant technologies such as in vitro tests, organoids, organs-on-a-chip and computational modeling to replace, reduce or refine ...

Since 2019, overall rates of nicotine vaping have declined among U.S. youth, but those who continue to vape are showing signs of worsening addiction, according to new USC research. Between 2020 and 2024, the share of current users who vaped every day increased from 15.4% to 28.8%. Over the same period, the share of daily users who tried to quit but were unable to rose from 28.2% to 53%. The study, funded in part by the National Institutes of Health, was just published in JAMA Network Open. Public health advocates raised the alarm when youth vaping rates surged between 2014 and 2019. Data collected during the COVID-19 ...

A glacier on Antarctica’s Eastern Peninsula experienced the fastest retreat recorded in modern history—in just two months, nearly 50 percent of the glacier disintegrated.  A new CU Boulder-led study, published today in Nature Geoscience, details how and why Antarctica’s Hektoria Glacier retreated at an unprecedented rate in 2023, losing a total of eight kilometers of ice in two months. The main driver was the glacier's underlying flat bedrock that enabled the glacier to go afloat after it substantially thinned, causing a rare calving process.  The new findings may help researchers identify other glaciers to monitor for rapid ...

The same cellular renewal that keeps our bodies healthy might also fuel the growth of cancer. A UC Merced biologist has found that the brain could hold the key to stopping it. Professor Néstor Oviedo, a molecular and cell biologist and affiliate of the Health Sciences Research Institute, received more than $2 million from the National Institutes of Health to investigate signals mediating the earliest stages of cancer development. His findings could one day change how doctors think about treating cancer and age-related diseases. “Our initial data suggest that key cancer symptoms can be selectively removed by activating signals from the nervous system,” ...

Computer-generated holography (CGH), as one of the most attractive next-generation three-dimensional (3D) display technology, possesses the capacity to provide authentic depth cues of 3D scenes via faithfully recording the optical field with computational simulations and loading the calculated holograms to reconstruct the target scenes. However, the process of hologram generation is predominately an ill-posed inverse problem, since only the intensity or amplitude information of the target scene is known while the original wavefront phase remains inaccessible ...

The last experimentally fundamental passive circuit element is the memristor that was originated in 2008 by Dmitri Strukov and presents a thin-film dielectric material with oxygen vacancies placed between two electrodes. This element changes its resistance based on the amount and direction of current that has flowed through it and its resistance has non-linear behavior from the current flow. Memristors are used in neuromorphic computing, data storage systems, and various devices for information processing and consume less power than basic silicon transistors. These elements are an attractive subject for modern scientific community due to their advantages ...

Missing Context in Single-Cell Data Single-cell RNA sequencing has transformed biology by showing which genes are active in individual cells. However, this approach requires cells to be removed from their natural environment, erasing information about their position and neighbors. Spatial transcriptomics preserves this context but is technically more limited and harder to scale. Researchers have long lacked a way to study cell identity and tissue organization together. AI Model Reveals Hidden Tissue Structures Nicheformer overcomes this barrier by learning from both dissociated and spatial data. It can “transfer” spatial context back onto cells that were previously ...

From medical microrobots to flexible sensors, the next generation of technology depends on devices that are smaller, smarter, and more capable than ever before. But building these intricate structure, often just micrometers across, requires extraordinary precision, not only in shaping materials but in programming their properties. In the International Journal of Extreme Manufacturing, a team of Chinese researchers reviews the fast-growing field of Field-assisted Additive Manufacturing (FAM)—a method that combines 3D printing with external fields such as magnetic, acoustic, or electric stimuli to precisely guide materials as they form. "Traditional ...

Chemists at the National University of Singapore (NUS) have found a new use for deoxyribonucleic acid (DNA), not just as genetic material, but as a tool for more efficient production of medicinal compounds. Certain parts of DNA, called phosphates, can act like tiny “hands” that guide chemical reactions to selectively produce the desired mirror-image version of a compound. Many medicinal compounds are chiral, meaning they come in two mirror-image forms, like right and left hands, that can behave very differently in the body. This is an important aspect because many drugs only work in ...

Renewable energy of the future is concentrated solar power because it can be easily used to store thermal energy. Despite the fact that, historically, it is more expensive and complex than photovoltaic power, in recent years huge advances have taken place in this technology, and concentrated solar power plants are spreading across more and more countries as a source for a sustainable future. As Iñigo González de Arrieta, a researcher in the Thermophysical Properties of Materials group of the University of the Basque ...
