A research team develops a radiative cooling material that is transparent under direct sunlight.

A genome of photosynthetic animals decoded

Posted: 15 Jul 2021 11:24 AM PDT

Some sea slugs take up chloroplasts from the algae that they consume into their cells. These chloroplasts retain their ability to perform photosynthetic activity within the animal cells for several months, and thus provide them with photosynthesis-derived nutrition. Researchers have published the genome of the sea slug, Plakobranchus ocellatus.

'Get out of the water!' Monster shark movies massacre shark conservation

Posted: 15 Jul 2021 11:23 AM PDT

Undeniably the shark movie to end all shark movies, the 1975 blockbuster, Jaws, not only smashed box office expectations, but forever changed the way we felt about going into the water - and how we think about sharks.

Fossil rodent teeth add North American twist to Caribbean mammals' origin story

Posted: 15 Jul 2021 09:45 AM PDT

Two fossil teeth from a distant relative of North American gophers have scientists rethinking how some mammals reached the Caribbean Islands.

Modified yeast inhibits fungal growth in plants

Posted: 15 Jul 2021 09:45 AM PDT

Engineers and plant pathologists have developed a way to engineer a protein that blocks fungi from breaking down cell walls, as well as a way to produce this protein in quantity for external application as a natural fungicide. The work could lead to a new way of controlling plant disease that reduces reliance on conventional fungicides.

Human waste contaminating urban water leads to 'superbug' spread

Posted: 15 Jul 2021 09:45 AM PDT

Contamination of urban lakes, rivers and surface water by human waste is creating pools of 'superbugs' in Low- and Middle-Income Countries (LMIC) - but improving access to clean water, sanitation and sewerage infrastructure could help to protect people's health, a new study reveals.

Spending time outdoors has positive effect on our brains

If you're regularly out in the fresh air, you're doing something good for both your brain and your well-being.

Bioengineering discovery paves way for improved production of bio-based goods

Posted: 15 Jul 2021 07:30 AM PDT

Scientists have uncovered a way to control many genes in engineered yeast cells, opening the door to more efficient and sustainable production of bio-based products.

Fluorescence lighting helps detect impurities in water

Posted: 15 Jul 2021 06:08 AM PDT

Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. Researchers are testing the use of fluorescence to monitor water quality. The results, they say, show great promise.

New method makes vital fertilizer element in a more sustainable way

Posted: 14 Jul 2021 12:11 PM PDT

Scientists and engineers have devised a new method for making urea that is more environmentally friendly than today's process and produces enough to be competitive with energy-intensive industrial methods.

Roadless forests see more blazes and greater severity, but fire resilience is the result

Posted: 14 Jul 2021 12:11 PM PDT

Roadless national forests in the American West burn more often and at a slightly higher severity than national forests with roads, but the end result for the roadless forests is greater fire resilience, researchers say.

The delicate balance of protecting river deltas and society

Posted: 14 Jul 2021 12:11 PM PDT

Researchers have created a novel analysis tool that seeks to protect the millions of people living on urban river deltas, while preserving the environmental and commercial viability of these landscapes.

Disparities of climate change mapped

Posted: 14 Jul 2021 12:11 PM PDT

New research illustrates the disparity between the narrow origins and far-reaching impacts of greenhouse emissions responsible for disrupting the global climate system.

How climate change and fires are shaping the forests of the future

Posted: 14 Jul 2021 10:19 AM PDT

As temperatures rise, the risk of devastating forest fires is increasing. Researchers are using artificial intelligence to estimate the long-term impact that an increased number of forest fires will have on forest ecosystems. Their simulations show how Yellowstone National Park in the USA could change by the end of the century.

No more cone? Psychology researchers offer better tool for visualizing hurricane danger

Posted: 14 Jul 2021 10:19 AM PDT

Researchers are working on an easily understood, science-backed way to visually represent hurricane danger to the general public. They contend that the cone of uncertainty creates a false sense of security for people who live outside the boundary of the cone and that there are better ways to signal likely impacts.
