The bunnies, and the digital files that described them, remained identical over many months.“This is a very initial foray into one of the more promising applications of DNA data storage: ubiquitous storage,” says Sriram Kosuri, a biochemist at UCLA who was not involved in the work.

The Chernobyl Disaster Might Have Also Built a Paradise

“If you go to the most contaminated areas, like some sites in the Red Forest, on a spring day you can barely hear a single bird singing,” says Anders Møller, an ecologist at the University of Paris-Sud who has been studying Chernobyl since 1991.

Scientists reach new understanding of main threats to Hector’s and Māui dolphins

Scientists reach new understanding of main threats to Hector’s and Māui dolphins

The 18-month scientific study has discovered: The dolphins can breed earlier, live longer and are capable of faster population growth than previously thought, which makes them more resilient to human threats Scientists can accurately predict where they live using satellite data on seawater turbidity (cloudiness) and the distribution of their main prey The importance of non-fishery threats had been underestimated, including the parasite causing toxoplasmosis, which is spread by cats.

Humans Made This Planet Hell. Hopefully We Can Help Some Species Adapt

Theoretically, this genetic diversity would make the bats more resilient to climate change, because a population that’s more adapted to arid conditions can interbreed with a population that’s less so, in essence “gifting” the cold-adapted population the genes necessary to survive a warmer world.

Harnessing creativity for change: The art of resilience

In an era of increasing natural hazards and climate change, art can also communicate the future risks we face. Last year, on the sidelines of FOSS4G and Understanding Risk Tanzania, a mural challenge brought together young Tanzanian artists to communicate visually about risk and resilience.

But a massive effort to catalogue the sex ratios at birth, for the first time, for every country, shows that’s not such a smart strategy after all.“For so long people just took that number for granted,” says Fengqing Chao, a public health researcher at the Institute of Policy Studies in Singapore.

Clues to Our Unknown Ancestors Are Hiding in Our Genome

“We could use an infinite amount of data to train the deep learning engine, because we were using simulations.” The researchers generated tens of thousands of simulated evolutionary histories based on differing combinations of demographic details: the number of ancestral human populations, their sizes, when they diverged from one another, their rates of intermixing and so on.

Our children’s planet: What does their education have to do with climate change?

Helping with that transition is an especially important challenge for the World Bank because most of the population growth in the coming decades will be in developing countries. I like to think that Korea’s embrace of sustainability was in part facilitated by World Bank supported environmental education programs in the 1990s.

The Evolutionary Importance of Neutral vs. Adaptive Genes

The Evolutionary Importance of Neutral vs. Adaptive Genes

For most of the first half of the 20th century, population geneticists largely attributed genetic differences between populations and species to adaptation through positive selection.Motoo Kimura proposed in 1968 that most mutations might be neutral in effect rather than beneficial or harmful, and that shifts in the frequency of these neutral mutations dominated evolutionary change at the genomic level.Annual ReviewsBut in 1968, the famed population geneticist Motoo Kimura resisted the adaptationist perspective with his neutral theory of molecular evolution.

Five takeaways for better nutrition in South Asia—and beyond

Overall, the event underscored how governments and health authorities in many developing countries face the dilemma of how to feed their growing population while ensuring their food is nutritious and discussed relevant strategies to transform nutrition security challenges into opportunities. As rice prices increase, relative to nutrient-rich foods, people will diversify their diets away from rice.
