How to use statistics to prepare for the next pandemic

Many governments, including the US, already collect and make public population statistics that could help them prepare for the next pandemic.

DNA ‘Lite-Brite’ is a promising way to archive data for decades or longer

DNA has been storing vast amounts of biological information for billions of years. Researchers are working to harness DNA for archiving data. A new method uses light to simplify the process.
Does being told that a veggie burger, like the one on the right, is better for the environment make you more likely to choose it over beef? AP Photo/Nati Harnik

Taste alone won’t persuade Americans to swap out beef for plant-based burgers

New research shows that consumers are more likely to choose a plant-based meat option if they’re informed of their social benefits – or the environmental costs of beef consumption.

How many Tyrannosaurus rex walked the Earth?

Using the incredible wealth of fossil data and a modern ecological theory, researchers estimated population density for the extinct apex predator.

Astrocyte cells in the fruit fly brain are an on-off switch that controls when neurons can change and grow

Adaptable neurons are tied to learning and memory but also to neurological disorders. By studying fruit flies, researchers found a mechanism that controls neuroplasticity.

Move over, corn and soybeans: The next biofuel source could be giant sea kelp

Making biofuels from crops grown on land poses trade-offs between food and fuel. A new study looks offshore.

Project-based learning deepens science knowledge for 3rd graders in Michigan

Students who took part in the program scored 8% higher on the state science test than students who received traditional instruction, and demonstrated greater social and emotional learning.

Culture matters a lot in successfully managing a pandemic - and many countries that did well had one thing in common

A new study finds egalitarian nations have had fewer COVID-19 deaths than individualistic ones like the US, a new study finds. But women’s leadership may have something to do with their success, too.
