Want to make a super strong material from nano-scale building blocks? Start with the highest quality building blocks, right?
Wrong -- at least when working with "flakes" of graphene oxide (GO).
Unlike animals, plants cannot move and tap into new resources when there is a scarcity or lack of nutrients. Instead, they have to adapt to the given situation. They do so by activating sets of stress-specific genes As a result, they basically reprogram their metabolism.
A group of researchers led by Skoltech Professor Pavel Troshin studied coordination polymers, a class of compounds with scarcely explored applications in metal-ion batteries, and demonstrated their possible future use in energy storage devices with a high charging/discharging rate and stability. The results of their study were published in the journal Chemistry of Materials.
Researchers have used artificial intelligence to make new discoveries, and confirm old ones, about one of nature's best-known mimics, opening up whole new directions of research in evolutionary biology.

The All of Us Research Program at the National Institutes of Health has made strong progress in its efforts to advance precision medicine, according to program leadership in a forthcoming paper in the New England Journal of Medicine.
CHICAGO --- Experts have turned the tables on hospital rating systems and graded the rating systems on their strengths and weaknesses. Most only got "C's" and "D's." The highest grade received was a "B" by U.S. News & World Report, according to a new study.
The study, "Rating the Raters," will be published Aug. 14 in the New England Journal of Medicine Catalyst. It grades the four major publicly reported hospital quality rating systems in the U.S.
A new study is the first to demonstrate that schooling in fishes can be facilitated by bioluminescent flashes in the absence of ambient light. Led by researchers at the American Museum of Natural History, the research raises the possibility that fish schooling may occur in the deep sea, where it was previously assumed to be too dark for fish to coordinate their movements with each other. The study is published today in the journal PLOS ONE.
(New York, NY - August 14, 2019) -- Early-life exposure to the mineral manganese disrupts the way different areas of the brain involved in cognitive ability and motor control connect in teenagers, Mount Sinai researchers report in a study published in PLOS ONE in August.
Researchers at the University of Waterloo have integrated the use of blockchain into energy systems, a development that could result in expanded charging infrastructure for electric vehicles.
In a study that outlines the new blockchain-oriented charging system, the researchers found that there is a lack of trust among charging service providers, property owners and owners of electric vehicles (EVs).
DURHAM, N.H.-- Researchers from the University of New Hampshire's Marine School are part of the crew, led by National Geographic Explorer-at-Large Robert Ballard, that is setting out to hopefully find answers to questions around the disappearance of famed pilot Amelia Earhart. UNH's Center for Coastal and Ocean Mapping has developed an autonomous surface vehicle (ASV), or robot, that can explore the seafloor in waters that may be too deep for divers.
Tiny nanoparticles play a gargantuan role in modern life, even if most consumers are unaware of their presence. They provide essential ingredients in sunscreen lotions, prevent athlete's foot fungus in socks, and fight microbes on bandages. They enhance the colors of popular candies and keep the powdered sugar on doughnuts powdery. They are even used in advanced drugs that target specific types of cells in cancer treatments.
Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
A study published this week in the journal Pigment Cell & Melanoma Research has found that genes have a greater influence than previously thought not only on the number of moles you have but also where they are on your body.
Survival of skin cancer is known to be influenced by gender, with female patients demonstrating higher rates of survival linked to the melanoma sites tending to occur in the lower body, rather than men, who tend to be affected in the upper body, neck and scalp.
This summer alone, intense heat waves have been to blame for at least 11 deaths in Japan, a record-breaking 45.9-degree Celsius temperature in France, and a heat advisory affecting 147 million people on the U.S. East Coast.
Everyone's talking about CRISPR-Cas. This biotechnological method offers a relatively quick and easy way to manipulate single genes in cells, meaning they can be precisely deleted, replaced or modified. Furthermore, in recent years, researchers have also been using technologies based on CRISPR-Cas to systematically increase or decrease the activity of individual genes. The corresponding methods have become the worldwide standard within a very short time, both in basic biological research and in applied fields such as plant breeding.
