Basement membrane underpins tissue interactions in the skin
In a discovery that could pave the way for therapies that promote wound healing and alleviate skin diseases, RIKEN researchers have found that the network of molecules under the outermost layer of mouse skin, the skin epithelium, is a highly speciali.....»»
Damage to cell membranes causes cell aging, finds new study
Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue injury. To cope with such damage, cells are equipped w.....»»
Paleontological analysis shows renowned fossil thought to show soft tissue preservation is in fact just paint
A 280-million-year-old fossil that has baffled researchers for decades has been shown to be—in part—a forgery, following new examination of the remnants......»»
Important molecular pathway for control of aging discovered
One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) in Brazil found that when t.....»»
"The Sims 4" adds vitiligo in free update
"The Sims 4" has released a new update adding vitiligo to its character creator, partnering with Winnie Harlow for the launch. The Sims 4 is adding vitiligo in a free update, allowing players to create Sims with the skin condition. The new patc.....»»
AutoNation cut back regional executives, reports $7 million in severance expenses

Researchers directly detect interactions between viruses and their bacterial hosts in soil
Bacteriophages—viruses that infect bacteria—are common in soil ecosystems. However, many of these phages have not been identified, and the bacteria they target are also a mystery......»»
We"re social beings: So are the microbes in our microbiomes
The COVID-19 pandemic reminded us that social interactions transmit pathogens. But do humans spread "good" bugs, too? Very much so, say a team of biologists who are probing the links between the microbiome and health......»»

A new approach to producing artificial cartilage with the help of 3D printing
Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken toward creating replacement tissue in the lab—using a technique that differs significantly from oth.....»»
New 3D printing method uses ice to build a template for artificial blood vessels in engineered tissue
Over 100,000 individuals in the United States are currently in need of organ transplants. The demand for organs, such as hearts, kidneys, and livers, far exceeds the available supply and people sometimes wait years to receive a donated organ. Approxi.....»»
New AI tool discovers realistic "metamaterials" with unusual properties
A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue—these extraordinary objects are already made from "metamaterials." Researchers from TU Delft have now developed an AI tool that not only can discove.....»»
Physicist advancing skin cancer screening and diagnosis using terahertz waves
Ahead of International Day of Women and Girls in Science this Sunday, 11 February, The University of Warwick is shining the spotlight on a physicist who is developing new technology to advance the diagnosis and screening of skin cancers......»»
Novel hydroxyapatite-targeting nanodrug may be a paradigm shift for cancer treatment
A multidisciplinary research team at Vanderbilt University and Vanderbilt University Medical Center has discovered a new way to kill a tumor by disrupting its acidic "microenvironment" without harming normal tissue......»»
Trained AI system learns to design cellular materials for tissue engineering, energy storage
Artificial structures called cellular materials have a network of internal spaces within a solid cell-like matrix. Their porous foam-like architecture combines advantages of low density with strength. Researchers at the National Institute for Materia.....»»
Probing proton pumping: New findings on protein folding in bacteriorhodopsin
When it comes to drug development, membrane proteins play a crucial role, with about 50% of drugs targeting these molecules. Understanding the function of these membrane proteins, which connect to the membranes of cells, is important for designing th.....»»
Revolutionizing next-generation VR and MR displays with a novel pancake optics system
Augmented reality (AR), virtual reality (VR) and mixed reality (MR) have expanded perceptual horizons and ushered in deeper human-digital interactions that transcend the confines of traditional flat panel displays......»»
Exploring new physics arising from electron interactions in semiconductor moiré superlattices
Semiconductor moiré superlattices are fascinating material structures that have been found to be promising for studying correlated electron states and quantum physics phenomena. These structures, made up of artificial atom arrays arranged in a so-ca.....»»
Team discovers mechanism that protects tissue after faulty gene expression
A study at the University of Cologne's CECAD Cluster of Excellence in Aging Research has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead.....»»
Study traces the roots of longstanding cultural interactions across the Tibetan Plateau to prehistoric times
The 1 million-square-mile Tibetan Plateau—often called the "roof of the world"—is the highest landmass in the world, averaging 14,000 feet in altitude. Despite the extreme environment, humans have been permanent inhabitants there since prehistori.....»»
