More than 420,000 children in the Amazon basin are being badly affected by a drought parching much of South America that is impacting water supplies and river transport, UNICEF said Wednesday......»»
The natural environment is declining—are companies doing their part to save it?
The natural environment across the globe is deteriorating, leading to crises like climate change, biodiversity loss, and water scarcity. Companies and industries play a major role in this decline, and they are expected to take responsibility for thei.....»»
Ethiopia"s famed honeybees make slow recovery from war
In his stone house perched on a hill in northern Ethiopia, Amanuel Hiluf puts on his protective suit, carefully adjusting the hood and gloves......»»
Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat crude but helpful fir.....»»
Pathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a study led by Ingun Lund Witsø of the Norwegian University of Life Sciences, published November 6, 2024 in the open-access journal.....»»
New PFAS testing method could make water testing more affordable, portable and accessible
University of Massachusetts Amherst researchers have discovered a new way to detect per- and polyfluoroalkyl substances (PFAS) in water. This marks an important step forward in creating testing devices that are simpler, more cost-effective, faster an.....»»
Food security in Africa: Managing water will be vital in a rapidly growing region
Sub-Saharan Africa's population is growing at 2.7% per year and is expected to reach two billion by the year 2050. The region's urban population is growing even faster: it was at 533 million in 2023, a 3.85% increase from 2022......»»
The frozen carbon of the northern permafrost is on the move—we estimated by how much
Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the Arctic. This region is warming two to four times faster than the global average......»»
New bird flu outbreak confirmed in UK
The UK government warned bird keepers to remain vigilant after bird flu was detected at a commercial poultry farm in northern England, the second outbreak this year and first of the season......»»
New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
Soil sampling in Houston"s greater Fifth Ward reveals toxic levels of lead in yards, play areas
Houston, like many American cities, has areas with soil contaminated by non-biodegradable and persistent pollutants such as arsenic, lead, nickel and cadmium, known as heavy metals and metalloids. These are both naturally occurring in the atmosphere.....»»
Braving sharks and hordes of urchins, scientists are growing kelp one forest at a time
The weathered UC Davis Marine Laboratory looms in thick fog on the edge of the ocean near Bodega Bay. Inside, an experiment is playing out that gives a badly-needed boost to Northern California's kelp forests—underwater cathedrals of green and gold.....»»
Water overuse in Brazil"s MATOPIBA region could mean failure to meet up to 40% of local demand for crop irrigation
Considered one of the fastest-growing agricultural frontiers in Brazil, and the area with the highest greenhouse gas emissions in the Cerrado, Brazil's savanna-type biome, the region known as MATOPIBA, risks facing water shortages in the years ahead......»»
Scientists find key to engineering water-responsive biopolymers
Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have developed a novel approach to better understand and predict the behaviors of water-responsive materials—solid matter that can change shape by absorbing.....»»
Sustainable hydrophobic cellulose shows potential for replacing petroleum-related products
A recent study has aimed to create hydrophobic paper by exploiting the mechanical properties and water resistance of cellulose nanofibers, and so produce a sustainable, high-performance material suitable for packaging and biomedical devices. This inv.....»»
Smog sickness: India"s capital struggles as pollution surges
The toxic smog season in India's capital has just begun, but those unable to escape cancer-causing poisonous fumes say the hazardous impact on health is already taking its toll......»»
Exploring how microbes in permafrost contribute to nitrous oxide emissions
Ecologist Christina Biasi is exploring the conditions under which tiny organisms contribute to permafrost soils emitting nitrous oxide. Her research could be essential for the development of future climate scenarios......»»
Organosilicon chemistry offers options for replacing PFAS in food and medical industries
Due to the unique properties of PFAS, almost no other chemical substances can compete with them. That explains why it is so hard to find a replacement for these toxic "forever chemicals," which accumulate in the environment and do not break down over.....»»
Ethiopian farmers improve soil and feed with forage mixtures
Yordanos Anju is a dedicated farmer from the Bilate Zuria district in the Northern Sidama region. For generations, his family has relied on farming and livestock production......»»
Dams have taken half the water from Australia"s second biggest river—and climate change will make it even worse
The largest wetland on Australia's second longest river, the Murrumbidgee in the southern Murray-Darling Basin, is drying up. This is bad news for the plants, animals and people who rely on the vast Lowbidgee Floodplain. So it's important to understa.....»»
