In your quest for true love and that elusive happily ever after, are you waiting for the "right" person to come along, or do you find yourself going for the cutest guy or girl in the room, hoping things will work out? Do you leave your options open, hoping to "trade-up" at the next opportunity, or do you invest in your relationship with an eye on the cost-benefits analysis?
New research by Christopher A. Williams, an environmental scientist and professor in Clark University's Graduate School of Geography, reveals that deforestation in the U.S. does not always cause planetary warming, as is commonly assumed; instead, in some places, it actually cools the planet. A peer-reviewed study by Williams and his team, "Climate Impacts of U.S. Forest Loss Span Net Warming to...
Using observations from NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a trio of hot worlds larger than Earth orbiting a much younger version of our Sun called TOI 451. The system resides in the recently discovered Pisces-Eridanus stream, a collection of stars less than 3% the age of our solar system that stretches across one-third of the...

Astrocytes -- star-shaped cells in the brain that are actively involved in brain function -- may play an important role in stuttering, a study led by an expert on stuttering has found. The study also suggests that treatment with the medication risperidone leads to increased activity of the striatum in persons who stutter.
Australian Antarctic Division will drill 3,000 metres deep in bid to improve ancient climate records and future modelsAntarctic scientists are close to finalising a drilling location deep in the frozen continent’s interior that could reveal a continuous record of the Earth’s climate going back 1.5 million years.After almost a decade of work, scientists at the Australian Antarctic Division are...
In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers.
A new study published in the journal Science Advances shows that Bantu-speaking communities in the Congo rainforest underwent a major population collapse from 1600 to 1400 years ago, probably due to a prolonged disease epidemic, and that significant resettlement did not restart until around 1000 years ago. These findings revise the population history of no less than seven present-day African...
A little more than one per cent of the Gulf of St. Lawrence is covered in ice this week, when in a normal year almost a third would be iced in, according to a release from Environment...

Humpback and bowhead whales are the only mammals other than humans thought to progressively change the songs they sing through a process of cultural learning.
The 10-member team made discoveries about a specific area of the brain tied to recollection and the desire to seek and consume food. It could lead to a way to inhibit the desire to overeat.
