Scientists have developed a new science-based indicator to assess the state of health of the oceans -- and the possible risk of extinction of their species. Recent biodiversity studies show an unprecedented loss of species, ecosystems and genetic diversity on land, but the extent to which these patterns are widespread...
Desert dust collected from glacier ice helps document climate change
Researchers are using dust trapped in glacier ice in Tibet to document past changes in Earth's intricate climate system -- and maybe one day help predict future changes.
Largest known manta ray population is thriving off the coast of Ecuador, new research shows
Scientists have identified off the coast of Ecuador a distinct population of oceanic manta rays that is more than 10 times larger than any other known subpopulation of the species.
Johns Hopkins APL Uses AI, Satellite Images to Track Greenhouse Emissions
The Environmental Protection Agency estimates that the transportation sector accounts for approximately 27% of all greenhouse gas emissions annually in the United States, and emissions from road transportation — driven by carbon-creating internal combustion vehicles — account for a large majority of that.
Honey Bee Lifespans are 50% Shorter Today Than They Were 50 Years Ago
A drop in longevity for lab-kept honey bees could help explain colony losses and lower honey production in recent decades.
Climate Change Creates Complications for Concrete
Pennsylvania drivers know the effects that weather can have on paved roads—potholes, cracks and other pavement woes are a common occurrence.
Half of replanted tropical trees don’t survive
On average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years, but there is enormous variation in outcomes, new research has found.
Researchers produce first-ever ‘family tree’ for aquarium-bred corals
The first-ever family tree for aquarium-bred corals provides insights for maximizing genetic diversity and adaptability in corals bred for conservation.
Designing and programming living computers
Bringing together concepts from electrical engineering and bioengineering tools, scientists collaborated to produce cells engineered to compute sophisticated functions -- 'biocomputers' of sorts. Researchers worked to create genetic 'devices' designed to perform computations like artificial neural circuits.
Fluorescent mouse blood will help us gain knowledge about brain diseases
A fluorescent protein makes it possible to follow disease progression in brain diseases such as Alzheimer's, strokes, and depression. That may lead to better insight into diseases and possible new treatments.
