New Findings Debunk Popular Belief About Dementia

People with dementia retain the ability to learn new skills, such as using a tablet, according to a doctoral study at Linköping University in Sweden. The study also indicates the importance of providing dementia patients with meaningful activities based on their own interests.According to a recent doctoral thesis recently presented at Linköping University, Sweden, people with dementia still have the ability to learn new things despite their illness. According to Elias Ingebrand, who conducted the study, the findings…

Colorado River Basin megadrought caused by massive 86% decline in snowpack runoff

Credit: Sean Benesh via Unsplash The Colorado River Basin provides freshwater to more than 40 million people within the semi-arid southwestern United States, including major cities such as Las Vegas and Los Angeles. However, between 2000 and 2021 the basin experienced a megadrought (a severe drought lasting multiple decades), which researchers have suggested likely would not have…

When You Drop a Rock Overboard, What Happens to the Water Level?

Physics questions are the most fun when people don't immediately agree on the answer. What feels intuitive or obvious—sometimes isn’t. We can argue over the solution for hours of entertainment, and we might even learn something in the end.Here's one of these seemingly obvious questions that's been around a long time: Suppose a large rock is on a boat that is floating in a very small pond. If the rock is dumped overboard, will the water level of the pond rise, fall, or remain unchanged?Go ahead and debate it with your…

“Paradoxical” – Metastatic Breast Cancer’s Trojan Horse

A molecule called MHC-II (seen here in green) disguises metastatic breast cancer cells (red), allowing them to invade the lymph nodes and take root without provoking an immune response. Credit: Beyaz lab/Cold Spring Harbor LaboratoryLymph nodes act as one of the body’s first lines of defense against disease. From these organic control centers, immune cells are sent into battle against foreign invaders. But somehow, lymph nodes are also the first stop for most metastatic cancers.“It’s paradoxical,” Cold Spring Harbor…

New Imaging Technology Provides a Quick Look Inside a Human Being

Researchers from the Julius-Maximilians-Universität Würzburg (JMU) have developed a portable, radiation-free scanner using Magnetic Particle Imaging (MPI). This technique, capable of visualizing dynamic processes like blood flow in the human body, is based on the detection of magnetic nanoparticles administered as markers.Technologies like computed tomography, magnetic resonance imaging, positron emission tomography, and ultrasound are now integral parts of the medical domain, offering exclusive insights into human…

Efficient Energy Harvesting With “Law-Breaking” Device

Researchers have developed a device that can disrupt the relationship between the absorption and emission efficiencies of an object, essentially violating Kirchhoff’s law of thermal radiation. This law, in place for over 150 years, states that an object’s ability to absorb and emit energy is equal at each wavelength and angle of incidence. This breakthrough could significantly impact sustainable energy harvesting systems and certain types of camouflage technology. (Artist’s concept.)Scientists have developed a device that…

Unveiling the Risks of Selective Adaptation

Researchers investigated ‘super corals’ to understand their potential in countering the effects of climate change on coral reefs. The study reveals that while ‘super corals’ show significant resilience, this adaptation comes at a cost, including reduced genetic diversity and skeletal compromises. These discoveries challenge existing notions about coral resilience and underline the importance of considering genetic diversity and adaptability in restoration efforts.Scientists are studying ‘super corals’ as a potential…

A Powerful Electrocatalysis Research Platform

A schematic Illustration of Structural-controlled Pt-high-entropy-alloy (Pt-HEA) Model Catalyst Synthesis. Credit: Yoshihiro Chida et al.A research team has developed a new platform to study and control the atomic-level structure of high-entropy alloys’ surfaces. They found that platinum high-entropy alloys outperformed platinum-cobalt alloys in oxygen reduction reaction. These findings have broad applicability, and the team plans to use this platform for practical electrocatalysis in the future.High-entropy alloys…
