Published 'Game-changing' findings for sustainable hydrogen production


Hydrogen fuel could be a more viable alternative to traditional fossil fuels, according to University of Surrey researchers who have found that a type of metal-free catalysts could contribute to the development of cost-effective and sustainable hydrogen production technologies.
Published Reducing pesticide pollution and the intensity of harvesting can increase crop yield and contribute to climate change mitigation


Researchers have found that carbon sequestration and plant resilience as well as forage pasture yield can be increased through key adjustments in agricultural management. The results provide a roadmap for reducing pesticide loads in soils and the first steps towards increasing climate change mitigation while improving crop yield in grasslands.
Published This loofah-inspired, sun-driven gel could purify all the water you'll need in a day


Access to clean water is being strained as the human population increases and contamination impacts freshwater sources. Devices currently in development that clean up dirty water using sunlight can only produce up to a few gallons of water each day. But now, researchers in ACS Central Science report how loofah sponges inspired a sunlight-powered porous hydrogel that could potentially purify enough water to satisfy someone's daily needs -- even when it's cloudy.
Published What makes people care about the environment?


A new study analyzes the factors that drive environmental concern among Europeans in an effort to understand how we can bolster popular support for combating climate change.
Published Licorice leaf extract is a promising plant protectant for conventional and organic agriculture



A study reveals that licorice leaf extract is a potent bactericide and fungicide that can be used in conventional and organic agriculture.
Published New research suggests drought accelerated empire collapse



The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, scientists have used tree ring and isotope records to pinpoint a more likely culprit: three straight years of severe drought.
Published Unearthing the impact of moisture on soil carbon processes


Researchers are offering a new perspective on those processes, revealing that moisture is a critical driver in the regulation and sequestration of soil carbon stocks.
Published Surprises in sea turtle genes could help them adapt to a rapidly changing world


Around 100 million years ago, a group of land-dwelling turtles took to the oceans, eventually evolving into the sea turtles that we know today. However, the genetic foundations that have enabled them to thrive in oceans throughout the world have remained largely unknown.
Published Devastating cost of future coastal flooding for many developing nations predicted in new study


New global modelling predicts the devastating socioeconomic impacts of future extreme coastal flooding for developing nations caused by climate change, with Asia, West Africa and Egypt facing severe costs in the coming decades.
Published Why icicles are rippled


Winter is coming to an end; the last nights of below zero temperatures are here. In the morning, one still spots the occasional icicle on a gutter or car bumper. When you look at these icicles carefully, you may notice that they show a characteristic pattern of ripples -- always around one centimetre wide. What causes these ripples? Using an icicle machine of their own design, physicists and chemists investigated this question, and discovered that salt plays an important part in the formation process of the ripples.
Published Optimal layout for a hospital isolation room to contain COVID-19 includes ceiling vent


Researchers recently modeled the transmission of COVID-19 within an isolation room at the Royal Brompton Hospital in London, U.K. Their goal was to explore the optimal room layout to reduce the risk of infection for health care staff.
Published Glacial flooding threatens millions globally



Fifteen million people around the world are at risk from flooding caused by glacial lakes, with just four countries -- India, Pakistan, China and Peru -- accounting for more than half of those exposed.
Published Antarctica's ocean brightens clouds


The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high density of water droplets, due in turn to a chain of atmospheric processes that eventually connects back to the Southern Ocean's extraordinary phytoplankton productivity.
Published Plastic debris in the Arctic comes from all around the world


In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analyzed. According to the findings, one third of the plastic debris which still bore imprints or labels allowing an analysis of their origin came from Europe, and much of that number from Germany.
Published Changing climate conditions likely facilitated early human migration to the Americas at key intervals, research suggests



Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper shows.
Published More frequent atmospheric rivers hinder seasonal recovery of Arctic sea ice


The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.
Published A chat may help convert a peer to a pro-sustainability stance



Changing the mind of someone who is dismissive of efforts to protect the planet could be accomplished by sharing a pro-sustainability point of view during a conversation, new research suggests.
Published Pacific Northwest heat dome tree damage more about temperature than drought, scientists say



Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.
Published Dirty laundry: How much microfiber do we emit with our washing?


The UK's laundry releases microfibers weighing the equivalent of up to 1,500 double-decker buses in microfibers every year, according to new research.
Published Prehistoric human migration in Southeast Asia driven by sea-level rise


An interdisciplinary team of scientistshas found that rapid sea-level rise drove early settlers in Southeast Asia to migrate during the prehistoric period, increasing the genetic diversity of the region today.
