Highly sensitive sensors show promise in enhancing human touch

People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Surgeons, for example, find that gloves decrease their ability to manipulate soft tissues. Astronauts are also hampered by heavy spacesuits and find it difficult to work with equipment while wearing heavy gloves.

Study of stone-age engravings suggests they were created with aesthetic intention

A team of researchers from Denmark, Australia and South Africa has found evidence that suggests stone-age etchings found at two sites in South Africa were created with aesthetic intention and that they evolved over time. In their paper published in Proceedings of the National Academy of Sciences, the group describes experiments they carried out with volunteers looking at reproductions of stone-age engravings and what they learned from them.

Chinese Woman Visiting Hospital Puts on Giant Giraffe Costume as Protection from Coronavirus

The coronavirus has the whole world on edge, but in China, where the epidemic originated, people are taking every precaution to avoid catching the virus, even at the risk of looking ridiculous. A Chinese woman identified only as Ms. He went viral recently after being video-recorded while visiting a hospital in Luzhou, China’s south-western Sichuan […]

Researchers discover how cells clear misfolded proteins from tissues

Researchers in Japan have identified a new quality control system that allows cells to remove damaged and potentially toxic proteins from their surroundings. The study, which will be published February 18 in the Journal of Cell Biology, finds that the Clusterin protein and heparan sulfate proteoglycans combine to bring misfolded proteins into cells for degradation. The findings may lead to new therapeutic targets for neurodegenerative disorders, including Alzheimer's disease.

Generating realistic stock market data for deeper financial research

Financial markets are among the most well-studied and closely watched complex systems in existence. This rich literature on market modeling and analysis has led to many important innovations, such as automated tools for detecting market manipulation. But a large gap still exists between the current state-of-the-art and the powerful insights needed to fully understand the complex dimensions of market behavior.

The origins of surface roughness: Atomic deformation within and on the surface of a solid

Most natural and artificial surfaces are rough: Metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite its presence on all scales, from the atomic to the tectonic. Scientists suspect that rough fabricated surfaces are formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components, such as milling. Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such mechanical loads in computer simulations. The researchers found out that surfaces made of different materials, which show distinct mechanisms of plastic deformation, always develop surface roughness with identical statistical properties. They have published their results in Science Advances.

Japan’s “Poop Soil Master” Shunned Indoor Pooping 45 Years Ago

A 70-year-old Japanese man who describes himself as a professional “fundoshi”, or “poop soil master” has been moving bowels outdoors for almost half a centuries, and encouraging others to follow his example. Masana Izawa, a published mushroom and moss photographer, is famous for avoiding indoor toilets as much as he can. In fact, he prides […]
