Given the choice between ice cream and vegetables, for many people it'll be the ice cream. But sometimes it depends on the situation. If you'd eaten ice cream every day for a week, you might prefer the salad. Human preferences for different foods often depend on what's common fare and what's rare.

Over the recent decade, total human impacts to the world's oceans have, on average, nearly doubled and could double again in the next decade without adequate action. That's according to a new study by researchers from the National Center for Ecological Analysis and Synthesis (NCEAS) at UC Santa Barbara.

Deforestation in Colombia has been linked to armed conflict and forests' proximity to coca crops, the plant from which cocaine is derived.

A University of Queensland-led study found that conflict between illegal groups and the governmental military forces, proximity to coca plantations, mining concessions, oil wells and roads were all associated with increased deforestation.

UQ PhD student Pablo Negret said the study identified how local drivers of deforestation in tropical countries affect deforestation risk.

Under the leadership of the head of the laboratory for the synthesis of new crystalline materials of the Samara Center for Theoretical Materials Science (SCTMS) of the Samara Polytech candidate of chemical sciences Eugeny Alexandrov and the head of the department "Chemistry and Technology of Chemical Compounds of Nitrogen", doctor of technical sciences Andrei Pimenov, the synthesis of the first metal-organic polymeric materials, or metal-organic frameworks (MOFs).

New research led by Oxford University and Queen Mary University of London has resolved a pig paradox. Archaeological evidence has shown that pigs were domesticated in the Near East and as such, modern pigs should resemble Near Eastern wild boar. They do not. Instead, the genetic signatures of modern European domestic pigs resemble European wild boar.

LOUISVILLE, Ky. -- Everywhere you go there are stormwater detention basins built near large construction projects intended to control the flow of rainwater and runoff. Now, those basins might help in controlling nitrogen runoff into rivers and lakes, according to Lauren E. McPhillips, assistant professor of civil and environmental engineering at Penn State.

Given the recent remarkable advancements in genetics, it's easy to assume that 21st century scientists have at their disposal a clear, quick way to run a genomic sequence scan and find out which genes among thousands can be expressed and which cannot. Gene expression is the process by which information encoded within genes leads to key products, such as proteins.

Rainfall variations in the tropics not only potentially influence 40% of the world's population and the stability of the global ecosystem, but also the global hydrologic cycle and energy balance.

Beginning in the 20th century, a decline in northern tropical rainfall has been observed, with researchers unsure whether the decline stems from natural or anthropogenic causes.

New rainfall research has shed some light on this question, but left the final answer up in the air.

Tropical Storm Krosa is a large tropical cyclone. When NASA-NOAA's Suomi NPP satellite passed over the Northwestern Pacific Ocean, it captured a visible image of the massive storm.

The largest study ever conducted of its kind has identified where and how to save coral reef communities in the Indo-Pacific, according to an international group of scientists from WCS (Wildlife Conservation Society) and other conservation NGOs, government agencies, and universities. The study outlines three viable strategies that can be quickly enacted to help save coral reefs that are threatened by climate change and human impacts.

Irvine, Calif., Aug. 12, 2019 -- When Joleah Lamb strapped on a scuba tank and plunged into the ocean over a decade ago, it was the first of many expeditions to examine the effects of climate change and other human-produced factors on coral.

In discussions of anthropogenic climate change, carbon dioxide generally gets the spotlight, but it is not the only greenhouse gas spewed into the atmosphere by human activity, nor is it the most potent.

Methane is another greenhouse gas that is increasing in Earth's atmosphere because of humans. Methane is produced by human activity in much smaller amounts than carbon dioxide, but it is roughly 25 times more powerful as a greenhouse gas. Though it is often associated with cow flatulence, bovines are not the only human-associated source of methane.

Despite the buzz in recent years about other invasive insects that pose an even larger threat to agriculture and trees -- such as the spotted lanternfly, the stink bug and the emerald ash borer -- Penn State researchers have continued to study another damaging pest, the Asian longhorned beetle.

For centuries, the mental world of the mind and the physical world were treated as utterly distinct. While the movement of inanimate objects could be measured and ultimately predicted with the help of mathematics, the movement of organisms - their behavior - appeared to be shaped by different forces, under the control of the will.

ANN ARBOR--Asian carp are capable of surviving and growing in much larger portions of Lake Michigan than scientists previously believed and present a high risk of becoming established, according to a new modeling study from University of Michigan researchers and their colleagues.

Some previous studies suggested that low food levels in Lake Michigan could be a barrier to the establishment of bighead and silver carp, which typically feed on algae and other types of plankton. Bighead and silver carp are the two Asian carp species of greatest concern for the Great Lakes.
