Published Monkeys cause a stink in response to human noise



New research has found that monkeys increase their use of scent markings to compensate for human noise pollution. The study has investigated how primates change their communication strategies in response to noise pollution. The researchers studied endangered pied tamarins (Saguinus bicolor), which use both vocal calls and scent markings. The researchers found that the frequency of scent marking directly increased in line with noise decibel levels.
Published Sustainable energy for aviation: What are our options?


Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.
Published Efficient next-generation solar panels on horizon following breakthrough


A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer.
Published Plant and forest researchers do not 'anthropomorphize' plants



Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.
Published Chameleon-inspired coating could cool and warm buildings through the seasons


As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers -- or warm in the winters -- without additional energy.
Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery


A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published Tall buildings could be built quicker if damping models were correct, study finds


Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction



A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
Published Gene required for root hair growth, nitrate foraging found in grasses



Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed 'BUZZ,' causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.
Published Cheap and efficient catalyst could boost renewable energy storage


Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published How wind turbines react to turbulence


The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.
Published Predictive model could improve hydrogen station availability


Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers.
Published The pace of climate-driven extinction is accelerating



Studying a lizard species in Arizona mountains, researchers found 70 years' worth of climate-related extinction occurred in only seven years.
Published Tracking down the formation of cardenolides in plants



Scientists are investigating the previously largely unknown biosynthetic pathway that leads to the formation of cardenolides in plants. In a new study, they present two enzymes from the CYP87A family as key enzymes that catalyze the formation of pregnenolone, the precursor for the biosynthesis of plant steroids, in two different plant families. The discovery of such enzymes should help to develop platforms for the cheap and sustainable production of high quality steroid compounds for medical use.
Published Step change in upconversion the key to clean water, green energy and futuristic medicine


Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
Published Almost half of koala habitats will be under high bushfire threat by 2070


The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Mitochondrial genome editing technique yields useful traits



Tweaks to the mitochondrial genome hold the potential for better hybrid seed production or to introduce seedless fruits.
Published Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration


• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
Published Making hydrogen from waste plastic could pay for itself


Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
Published Protected nature reserves alone are insufficient for reversing biodiversity loss



Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.
