New findings report that a class of small RNAs (microRNAs), microRNA-29, can restore normal skin structure rather than producing a wound closure by a connective tissue (scar). Any improvement of normal skin repair would benefit many patients affected by large-area or deep wounds prone to dysfunctional scarring.
Research throws light on the mystery of why women are much more prone to autoimmune disorders: A molecule made by one X chromosome in every female cell can generate antibodies to a woman's own tissues.
While newly approved drugs for Alzheimer's show some promise for slowing the memory-robbing disease, the current treatments fall far short of being effective at regaining memory.
Adults treated with 14 days of intravenous injections of ginkgo diterpene lactone meglumine (GDLM) -- a combination of biologically active components of ginkgo biloba -- after an ischemic (clot-caused) stroke had better cognitive recovery at 14 days and 90 days.
Unexplained rapid weight loss in older people could be a sign of underlying disease and can be linked with increased risk of falls and fractures, as well as a poorer long-term prognosis.
Researchers demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.
New research focused on a population of cirl bunting reintroduced into Cornwall from 2006 as part of a major conservation program. It suggests that if the translocation of nestlings is deemed necessary for conservation purposes, it may not lead to long-term problems for communication and population persistence.
A collaborative group of researchers has potentially developed a means of controlling spin waves by creating a hexagonal pattern of copper disks on a magnetic insulator. The breakthrough is expected to lead to greater efficiency and miniaturization of communication devices in fields such as artificial intelligence and automation technology.
Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.
Fighting disease-causing bacteria becomes more difficult when antibiotics stop working. People with pre-existing conditions in particular can carry resistant germs and suffer from repeated infections for years, according to a new study.
Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old.
Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.
Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Researchers have traced the origin and evolutionary trajectory of plant immune receptors. Their discovery will make it easier to identify immune receptor genes from genomic information and could help in the development of pathogen-resistant crops.
Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.
A research team develops 3D-printed pneumatic logic modules that control the movements of soft robots using only air pressure. These modules enable logical switching of the air flow and can thus imitate an electrical control system. The modules make it possible for the first time to produce flexible and electronics-free soft robots entirely in a 3D printer using conventional printing material.
Short-chain fatty acids (SCFAs), which are produced by gut bacteria from dietary fiber, regulate our immune system, but the mechanism of their action remains unknown. In a recent study, researchers investigated how SCFAs interact with mast cells, a type of white blood cell that plays a central role in allergic reactions. Their findings and insights could lead to innovative and effective anti-allergy medications, supplements, and diets, paving the way for healthier lives.
Climate change poses a threat to yields and food security worldwide, with plant diseases as one of the main risks. An international team of researchers has now shown that further spread of the fungal disease wheat blast could reduce global wheat production by 13% until 2050. The result is dramatic for global food security.
Researchers have discovered a change in what scientists already knew about global warming dynamics. It had been widely accepted since the 1950s that global temperature rises were not consistent throughout the day and night, with greater nighttime warming being observed. However, the recent study reveals a shift in dynamics: with greater daytime warming taking place since the 1990s. This shift means that the temperature difference between day and night is widening, potentially affecting all life on Earth.
A team of researchers mapped out how flecks of 2D materials move in liquid -- knowledge that could help scientists assemble macroscopic-scale materials with the same useful properties as their 2D counterparts.
