Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report. Dubbed the NanoGripper, the nanorobotic hand also could be programmed to interact with other viruses or to recognize cell surface markers for targeted drug delivery, such as for cancer treatment.

Home testing kits and coordinated outreach substantially improve colorectal cancer screening rates

Colorectal cancer screening is an effective tool for catching the disease early when it's most treatable, yet it is underutilized at federally qualified health centers (FQHC). A new study demonstrated that a targeted intervention that paired mailing at-home colorectal cancer screening kits with coordinated follow-up tripled screening completion rates compared to usual care at FQHCs.

AI protein engineer capable of making proteins 'better, faster, stronger'

Engineered proteins are critical industrial and medical applications, ranging from vaccine development to making crops or food proteins more resilient. Scientists can engineer proteins to improve upon nature, but such experiments are time- and labor-intensive. Researchers have developed an AI-based protein design tool known as EVOLVEPro, which is already showing promise for several applications and could be used to help solve other medical challenges.

Researchers use artificial intelligence to diagnose depression

Depression is one of the most common mental illnesses. As many as 280 million people worldwide are affected by this disease, which is why researchers have developed an artificial intelligence (AI) model that helps to identify depression based on both speech and brain neural activity. This multimodal approach, combining two different data sources, allows a more accurate and objective analysis of a person's emotional state, opening the door to a new phase of depression diagnosis.

How children learned for 99% of human history

Unlike kids in the United States, hunter-gatherer children in the Congo Basin have often learned how to hunt, identify edible plants and care for babies by the tender age of six or seven. This rapid learning is facilitated by a unique social environment where cultural knowledge is passed down not just from parents but from the broader community. The research helps explain how many cultural traits have been preserved for thousands of years among hunter-gatherer groups across a wide range of natural environments in Africa.

Spinning fusion fuel for efficiency

A new method to increase fusion-fuel efficiency would involve aligning the quantum spin of deuterium and tritium and changing the mix of the two fuels. The approach could boost tritium-burn efficiency by up to 10 times, reducing tritium needs and lowering fusion system costs. The technique could lead to safer, more compact fusion systems, making fusion energy more practical and affordable.

How jetlag can disrupt our metabolism

Have you ever felt sluggish and out of sorts after a long-haul flight or a late-night shift? A new study has found that disruptions to our body clock, such as those experienced during jetlag, impact our metabolism -- but to a lesser extent than sleepiness and the primary clock in the brain.

Confinement may affect how we smell and feel about food

New research found confined and isolating environments changed the way people smelled and responded emotionally to certain food aromas. The team in this study compared 44 people's emotional responses and perception of eight food aromas in two environmental scenarios: sitting in reclined chairs that mimic astronauts' posture in microgravity; and then in the confined setting of the International Space Station (ISS), which was simulated for participants with virtual reality goggles. The research builds on previous work by the team and aims to help explain why astronauts report meals taste different in space and struggle to eat their normal nutritional intake over long missions, which has been reported in the news recently.

Machine learning and supercomputer simulations help researchers to predict interactions between gold nanoparticles and blood proteins

Researchers have used machine learning and supercomputer simulations to investigate how tiny gold nanoparticles bind to blood proteins. The studies discovered that favorable nanoparticle-protein interactions can be predicted from machine learning models that are trained from atom-scale molecular dynamics simulations. The new methodology opens ways to simulate efficacy of gold nanoparticles as targeted drug delivery systems in precision nanomedicine.
