Giant tortoise found in Galapagos is from species previously considered extinct, Ecuador confirms
Ecuador confirmed on Tuesday that a giant tortoise found in 2019 in the Galapagos Islands is a member of the species Chelonoidis phantasticus that was considered extinct a century ago. Galapagos National Park is preparing an expedition to search for more of the tortoises in an attempt to save the...

Prof Stephen Hawking's scientific papers and personal possessions to be saved for the nation.
Stephen Hawking’s office and archive gifted to UK to settle tax bill
Scientist’s treasure trove and personal objects to go to Science Museum and Cambridge University LibraryA vast treasure trove of papers and personal objects belonging to Stephen Hawking, from dizzying black hole theories to scripts for the Simpsons, have been acquired for the nation.It was announced on Thursday that Hawking’s archive and the contents of his university office have been acquired...
People prefer 'natural' strategies to reduce atmospheric carbon
Soil carbon storage, carbon capture and storage, biochar—mention these terms to most people, and a blank stare might be the response.
Widespread coral-algae symbioses endured historical climate changes
One of the most important and widespread reef-building corals, known as cauliflower coral, exhibits strong partnerships with certain species of symbiotic algae, and these relationships have persisted through periods of intense climate fluctuations over the last 1.5 million years, according to a new study led by researchers at Penn State. The findings suggest that these corals and their symbiotic...
Grocery taxes put low-income families at risk for food insecurity
Approximately one-third of all U.S. counties do not exempt grocery foods from the general sales tax, which means the lowest-income families living in those areas are most susceptible to food insecurity. New research from Cornell University finds that even a slight grocery tax-rate increase could be problematic for many.
GM's newest vehicle: Off-road, self-driving rover for moon
General Motors is teaming up with Lockheed Martin to produce the ultimate off-road, self-driving, electric vehicles—for the moon.
Few public-sector employees can contribute significantly to reaching sustainability goals
The province of Quebec is one of only a few jurisdictions to enshrine sustainable development into law. In 2006 the then-Liberal government of Jean Charest adopted the Sustainable Development Act, creating a framework for Quebec's public bodies to follow in order to achieve a better integration of sustainable development in its operations. This involved the creation of sustainability plans with...
Scientists find solution to measure harmful plastic particles in human sewage
Scientists have gotten up close and personal with human sewage to determine how best to measure hidden and potentially dangerous plastics.
No good decisions without good data: Climate, policymaking, the critical role of science
"If you can't measure it, you can't improve it." This concept is also true within the context of climate policy, where the achievement of the objectives of the United Nations Framework Convention on Climate Change (UNFCCC) is dependent on the ability of the international community to accurately measure greenhouse gas (GHG) emission trends, and consequently, to alter these trends.
A new 'gold standard' compound for generating electricity from heat
Thermoelectric power generators that make electrical power from waste heat would be a useful tool to reduce greenhouse gas emissions if it weren't for a most vexing problem: The need to make electrical contacts to their hot side, which is often just too hot for materials that can generate a current.
Adult roles build skills for children of Latinx immigrants
Children of Latinx immigrants who take on adult responsibilities exhibit higher levels of political activity compared with those who do not, according to University of Georgia researcher Roberto Carlos.
How antibiotic-filled poop helps 'bessbug' beetles stay healthy
The lifestyle of the horned passalus beetle, commonly known as the bessbug or betsy beetle, might seem downright disgusting to the average human: Not only does this shiny black beetle eat its own poop, known as frass, but it uses its feces to line the walls of its living space and to help build protective chambers around its developing young.
Research identifies climate-change refugia in dry-forest region
Several indicators point to the adverse impacts of climate change on the planet's vegetation, but a little-known positive fact is the existence of climate-change refugia in which trees are far less affected by the gradual rise in temperatures and changing rainfall regimes. Climate-change refugia are areas that are relatively buffered from climate change, such as wetlands, land bordering water...
Study finds ongoing evolution in Tasmanian Devils' response to transmissible cancer
University of Idaho researchers partnered with other scientists from the United States and Australia to study the evolution of Tasmanian devils in response to a unique transmissible cancer.
As cicadas emerge, wildlife prepare for a feast—rats included
It was June 2004, and the elephants at the Maryland Zoo in Baltimore were getting awfully sick of Brood X cicadas, which had emerged en masse after 17 years underground.
Study of promising photovoltaic material leads to discovery of a new state of matter
Researchers at McGill University have gained new insight into the workings of perovskites, a semiconductor material that shows great promise for making high-efficiency, low-cost solar cells and a range of other optical and electronic devices.
