Scientists have conducted a thorough examination of international trade in agricultural goods, finding that consumers in wealthy countries enjoy the produce while people in less-developed nations endure heightened greenhouse gas emissions and environmental degradation.
Historic graffiti made by soldiers sheds light on Africa maritime heritage, study shows
Historic graffiti of ships carved in an African fort were drawn by soldiers on guard duty watching the sea, experts believe.
Minerals can be key to healing damaged tissue
Every species, from bacteria to humans, is capable of regeneration. Regeneration is mediated by the molecular processes that regulate gene expression to control tissue renewal, restoration and growth.
Saving the Mekong delta from ‘drowning’
Southeast Asia's most productive agricultural region and home to 17 million people could be mostly underwater within a lifetime. Saving the Mekong River Delta requires urgent, concerted action among countries in the region to lessen the impact of upstream dams and better manage water and sediments within the delta, according...
‘Stressed’ cells offer clues to eliminating build-up of toxic proteins in dementia
It's often said that a little stress can be good for you. Now scientists have shown that the same may be true for cells, uncovering a newly-discovered mechanism that might help prevent the build-up of tangles of proteins commonly seen in dementia. Scientists have identified a new mechanism that appears...
Land-building marsh plants are champions of carbon capture
Human activities such as marsh draining for agriculture are increasingly eating away at saltwater and freshwater wetlands that cover only 1% of Earth's surface but store more than 20% of all carbon dioxide absorbed by ecosystems worldwide. A new study shows that it's not too late to reverse the losses...
Recurrent UTIs linked to gut microbiome, chronic inflammation
A study suggests that women who get recurrent urinary tract infections (UTIs) may be caught in a vicious cycle in which antibiotics given to eradicate one infection predispose them to develop another.
Invasive species and climate change impact coastal estuaries
Native species in California's estuaries are expected to experience greater declines as invasive species interact with climate change, according to a new study.
Why hungry worms take risks
Whether it's making rash decisions or feeling grumpy, hunger can make us think and act differently -- 'hangry,' even. But little is known about how hunger signals in the gut communicate with the brain to change behavior. Now, scientists are using worms as a model to examine the molecular underpinnings...
Cutting calories and eating at the right time of day leads to longer life in mice
In a study that followed hundreds of mice over their lifespans, calorie restriction combined with time-restricted eating boosted longevity.
