Reducing population is no environmental 'quick fix', modelling research shows
New multi-scenario modelling of world human population has concluded that even stringent fertility restrictions or a catastrophic mass mortality would not bring about large enough change this century to solve ...
New planetary dashboard shows 'Great Acceleration' in human activity since 1950
Human activity, predominantly the global economic system, is now the prime driver of change in the Earth System (the sum of our planet's interacting physical, chemical, biological and human processes), according ...
Plant geneticists demonstrate new means of boosting maize yields
A team of plant geneticists at Cold Spring Harbor Laboratory (CSHL) has successfully demonstrated what it describes as a "simple hypothesis" for making significant increases in yields for the maize plant.
Scientists probe Canadian sulfide ore to confirm microbial activity in seawater 2.7 billion years ago
An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively ...
Six degrees of separation? More like 4.74
Six Degrees of Kevin Bacon may be the name of the game but it takes less than that to connect any two users on Facebook.
Study shows how sea otters can reduce CO2 in the atmosphere
(Phys.org)—Can an abundance of sea otters help reverse a principal cause of global warming?
Spread of crop pests threatens global food security as Earth warms
A new study has revealed that global warming is resulting in the spread of crop pests towards the North and South Poles at a rate of nearly 3 km a year. The study, published in the journal Nature Climate Change and carrie ...
Some plants in arid regions benefit from climate change, study finds
(Phys.org)—Dryland ecosystems cover 41% of the Earth's land surface. These ecosystems are highly vulnerable to global environmental change and desertification. But climate change seems to have a positive ...
Global warming may be causing surge in numbers of pink salmon
Historic trends predict future global reforestation unlikely
Feeding a growing global population while also slowing or reversing global deforestation may only be possible if agricultural yields rise and/or per capita food consumption declines over the next century, ...
Global warming brings crab threat to Antarctica
The sea floor around the West Antarctica peninsula could become invaded by a voracious king crab, which is on the march thanks to global warming, biologists reported on Wednesday.
Researchers report breakthrough on salt-tolerant durum wheat
A team of Australian scientists has bred salt tolerance into a variety of durum wheat that shows improved grain yield by 25% on salty soils.
Large-scale edible insect farming needed to ensure global food security
The large-scale production of edible insects is unavoidable in order to continue feeding the ever-increasing global population and providing them with enough animal protein. Insect farming can be compared ...
Algal genes may boost efficiency, yield in staple crops
(Phys.org) —As humanity faces more mouths to feed thanks to a swelling global population, new research has taken a step toward employing genes from blue-green algae to improve staple crop photosynthesis ...
