For the first time, scientists have figured out how to determine the age of a lobster — by counting its rings, like a tree. Nobody knows how old lobsters can live to be; some people estimate they live to more than 100. But knowing — rather than simply guessing — their age and that of…
A consortium of scientists announced they had made major progress in deciphering the genome of bread wheat, a vital crop whose DNA is notoriously complex. Publishing in the journal Nature, they said they had analysed between 94,000 and 96,000 genes in bread wheat (Triticum aestivum). The plant’s genome is nearly five times as big as…
The race is on to blame everything related to ecological change on human footprints – even the past can be re-framed as anthropocenic climate change and University of Massachusetts Amherst geoscientists have shown how to do just that, by using a biomarker from human feces in a completely new way to establish the first human…
A U.S. start-up has turned to nature to help bring water to arid areas by drawing moisture from the air. NBD Nano aims to mimic the way a beetle survives in an African desert to create a self-filling water bottle capable of storing up to three litres every hour. The insect harvests moisture from the…
The first farmers who swept into Europe 6000 to 7000 years ago may have grown too big for their britches—or animal skins—too fast. A new study of archaeological sites across Western Europe highlights a strikingly consistent pattern in Neolithic farmers’ communities: Their populations grew too big, too quickly, and crashed right after they peaked. “We…
The World Bank is urging stepped-up efforts to meet world carbon reduction goals after looking at what it says would be the catastrophic consequences if average world temperatures rise more than 4 degrees Celsius (7.2 degrees Fahrenheit) by the end of the century. In what World Bank President Jim Yong Kim acknowledged was a “doomsday…
The UN Secretary-General’s high-level panel on life after the Millennium Development Goals (MDGs) — the Post-2015 Development Agenda — held its second meeting in London at the beginning of November. It’s a reminder that the time has come for all of us to plan our futures in line with the proposed Sustainable Development Goals (SDGs),…
Early human ancestors in central Africa 3.5 million years ago ate a diet of mostly tropical grasses and sedges, finds new research. The study suggests our relatives were mostly plant-eaters before they evolved a taste for meaty flesh. The study focused on Australopithecus bahrelghazali, which had quite a set of teeth. “No African great apes,…
Climate change, population growth and competing demands for land and resources are putting great pressure on the world’s food systems. Smallholder farmers in the developing world, who produce much of the food for the poorest people, are threatened by devastating droughts and floods, food price spikes, and persistent poverty. Scientific advances have greatly alleviated hunger…
Fragments of a 1.5-million-year-old skull from a child recently found in Tanzania suggest early hominids weren’t just occasional carnivores but regular meat eaters, researchers say. The finding helps build the case that meat-eating helped the human lineage evolve large brains, scientists added. “I know this will sound awful to vegetarians, but meat made us human,”…
