Protein-like molecules called "polypeptoids" (or "peptoids," for short) have great promise as precision building blocks for creating a variety of designer nanomaterials, like flexible nanosheets - ultrathin, atomic-scale 2D materials. They could advance a number of applications - such as synthetic, disease-specific antibodies and self-repairing membranes or tissue - at a low cost.
With many of the products we use every day held together by adhesives, researchers from UBC's Okanagan campus and the University of Victoria hope to make everything from protective clothing to medical implants and residential plumbing stronger and more corrosion resistant thanks to a newly-developed 'hyper glue' formula.
A flotilla of Vietnamese fishing boats with crews suffering in harsh conditions is stripping Pacific coral reefs of seafood as the poaching escalates to become an international human rights and security issue.
Dr Andrew Song, joint ARC Centre of Excellence for Coral Reef Studies and WorldFish research fellow at James Cook University, has produced the first analysis of international attempts to manage Vietnam's 'blue boat' fleet - small fishing vessels, commonly painted blue, that travel thousands of kilometres to fish illegally in Pacific waters.
The percentage of the world's population that is above or below the 'replacement level of fertility' has long been used as a measure of demographic development. A new study revisited how this metric is calculated and how useful it really is in terms of informing policy decisions.
An international group of scientists, including Andrey Savelyev, associate professor of the Institute of Physical and Mathematical Sciences and Information Technologies of the IKBFU, has improved a computer program that helps simulate the behavior of photons when interacting with hydrogen spilled in intergalactic space. Work results published in the scientific journal Monthly Notices of the Royal Astronomical Society.

NASA's Aqua satellite found that wind shear was tearing at Tropical Storm 07A in the Arabian Sea.
University of Canberra researchers have shown that art gallery programs can improve the wellbeing of people living with dementia - and they've backed it up by testing study participants' saliva.
Published in the Journal of Alzheimer's Disease, the UC study monitored new participants of the National Gallery of Australia's (NGA) Art and Dementia program over six weeks. The NGA program has been running for more than 12 years and has demonstrated anecdotal and observational benefits, now backed up by UC research.
OAK BROOK, Ill. - A sophisticated type of artificial intelligence (AI) can detect clinically meaningful chest X-ray findings as effectively as experienced radiologists, according to a study published in the journal Radiology. Researchers said their findings, based on a type of AI called deep learning, could provide a valuable resource for the future development of AI chest radiography models.
A specialised system of ducts transports bile and enzymes from the liver and pancreas to the intestine. In a new study, researchers from the University of Copenhagen have shown how this ductal system is formed. The new knowledge can help understanding how congenital diseases in that part of the body arise.
Graphene Flagship partners the University of Bologna, Politecnico di Milano, CNR, NEST, Italcementi HeidelbergCement Group, the Israel Institute of Technology, Eindhoven University of Technology, and the University of Cambridge have developed a graphene-titania photocatalyst that degrades up to 70% more atmospheric nitrogen oxides (NOx) than standard titania nanoparticles in tests on real pollutants.
Chemolithotrophic microorganisms derive their energy from inorganic sources. Research into the physiological processes of these organisms - which are grown on meteorite - provides new insights into the potential of extraterrestrial materials as a source of accessible nutrients and energy for microorganisms of the early Earth. Meteorites may have delivered a variety of essential compounds facilitating the evolution of life, as we know it on Earth.
VTT researchers were able to transmit light in wood-based fibre. Optical fibre made of cellulose is best suited for sensors that benefit from the biodegradability of the material. In the future, optical cellulose fibre may allow detecting changes in the moisture level of buildings.
Researchers find new way to convert carbon dioxide into a usable fuel source.
The concentration of carbon dioxide in our atmosphere is steadily increasing, and many scientists believe that it is causing impacts in our environment. Recently, scientists have sought ways to recapture some of the carbon in the atmosphere and potentially turn it into usable fuel — which would be a holy grail for sustainable energy production.
Along with the promise that CRISPR-Cas9 gene editing technology can offer new human therapies is the need to ensure its safety. A recent study showed that CRISPR-Cas9 did not produce off-target gene mutations in zebrafish. These results, published in Frontiers in Genetics, confirm previous data in animal models that the risk to the rest of the genome from gene editing is minimal.
Imagery from NASA-NOAA's Suomi NPP satellite showed that a tropical depression in the Arabian Sea has consolidated and organized despite facing wind shear. Tropical Depression 06A is now Tropical Cyclone 06A.
