Soft actuators today often rely on a single driving method, making it tough to handle complex, multi-directional movements. Scientists have crafted a new type of actuator using MXene, a special material, combined with a unique wrinkling structure. By adding n-hexane and letting it evaporate quickly,
Astronauts on the International Space Station, 260 miles (420 kilometers) above Earth, sent holiday cheer to those below with a festive video message. Commander Sunita "Suni" Williams, sporting reindeer antlers, joined NASA astronaut colleagues Barry "Butch" Wilmore, Don Pettit, and Nick Hague, plus
In the world of kidney dialysis, vascular access is crucial. One common type is the arteriovenous fistula (AVF). But how well does AVF work, and what affects its survival? That's what researchers set out to find in a one-year study. The study looked at how well AVFs functioned and survived in patie
Have you ever thought about how molecules hang out together? In the world of computational chemistry, figuring out these molecular friendships, especially with big, circular molecules called macrocycles, is a real puzzle. One of these macrocycles is called pillararene. Understanding how pillararene
Get ready for a wet start to the Boxing Day Test between Zimbabwe and Afghanistan! This is the first Test match at Queens Sports Club, Bulawayo, in nearly three decades for Zimbabwe. After facing tough times in shorter formats, they hope to put up a strong show. Afghanistan, fresh from dominating wi
As technology moves forward, traditional electronics face limits. For instance, Boltzmann's law and short-channel effects pose issues for metal-oxide-semiconductor field-effect transistors (MOSFETs). But there's a new kid on the block: nanoscale air channel transistors (NACTs), which use a vacuum-li
Irritable Bowel Syndrome (IBS) is a tough nut to crack, and finding new treatments is a top priority. Scientists have been experimenting with a special type of mouse that mimics human IBS symptoms. This mouse model is called the Chronic Vicarious Social Defeat Stress (cVSDS) model. Coincidentally, t
This Christmas morning, Ukraine woke up to a harsh reality. Russia unleashed a wave of missiles and drones targeting the country's energy infrastructure. The attack was so massive that it included 78 missiles and 106 drones, according to Ukraine's air force. The strikes hit several regions, includin
Pope Francis, standing before the world, celebrates Christmas by sharing a heartfelt message of hope, peace, and unity. He reminds us that 2, 000 years ago, Jesus was born, and God's heart remains open to all. It's a time for everyone to find reconciliation, with God and with each other. The Holy Do
Imagine a low-profile, yet crucial, crop called Dioscorea alata. This plant is under attack by a nasty disease called anthracnose, caused by a tiny critter named Colletotrichum gloeosporioides. The problem? D. alata is having trouble fighting back, and identifying the right genes to help it do so is
