Forest health on one coast can affect forests on the other coast

Forest health on one coast can affect forests on the other coast

Science
May 16 (UPI) -- Shrinking forests don't just have local or regional consequences. New research suggests the loss of forests on one coast can affect forest health on the opposite coast. In a new study, published this week in the journal Environmental Research Letters, scientists at the University of Washington detailed the linked fates of forests on the East and West coasts of the United States. Die-offs on one coast, whether caused by wildfire, drought or disease -- or some combination thereof -- can have a measurable impact on the health of sections of forest a few thousand miles away. "These smaller areas of forest can have continental-scale impacts, and we really need to be considering this when we're thinking about ecological changes," Abigail Swann, an assistant professor of atmosph...
These changes under the GOP tax plan affect homeowners

These changes under the GOP tax plan affect homeowners

Finance
After the many twists and turns that the Republican tax-overhaul legislation has taken thus far, it might be unclear to homeowners what's in store for them.In a nutshell, not much that will help them save more on taxes. The bill, expected to receive final approval by lawmakers on Wednesday, includes a variety of changes that could make homeownership a more costly proposition for some taxpayers.On top of making modifications to the mortgage interest deduction, the bill limits the deductibility of property taxes and state and local income taxes to a combined $ 10,000. In states such as New York and California where home prices and property taxes are high, this change means some homeowners could face bigger tax bills beginning next year.And if you were thinking about prepaying some of your 20...
More acidic oceans 'will affect all sea life'

More acidic oceans 'will affect all sea life'

Science
All sea life will be affected because carbon dioxide emissions from modern society are making the oceans more acidic, a major new report will say.The eight-year study from more than 250 scientists finds that infant sea creatures will be especially harmed.This means the number of baby cod growing to adulthood could fall to a quarter or even a 12th of today's numbers, the researchers suggest.The assessment comes from the BIOACID project, which is led from Germany.A brochure summarising the main outcomes will be presented to climate negotiators at their annual meeting, which this year is taking place in Bonn in November.The Biological Impacts of Ocean Acidification report authors say some creatures may benefit directly from the chemical changes - but even these could still be adversely affect...
More evidence contact sports can affect the brain

More evidence contact sports can affect the brain

Health
TUESDAY, Aug. 22, 2017 -- Playing contact sports like football or ice hockey can alter the structure and function of the brain, Canadian researchers report.Brain scans showed that these changes were particularly pronounced in sports that have the greatest risk of body contact."There is growing concern about the risk of collisions in sport. However, most of the research has focused on retired professional athletes with decades of exposure to head impacts," said lead researcher Nathan Churchill. He's a post-doctoral fellow in the neuroscience research program at St. Michael's Hospital in Toronto."Far less is known about the consequences of repeated body-to-body contact for young, active athletes," he said.In a group of college athletes, researchers found differences in the brains of both men...
How and why does light affect sleep?

How and why does light affect sleep?

Science
June 23 (UPI) -- Many studies have explored the effects of light on the circadian rhythms of plants and animals, including humans. But few have looked at the direct effects of light on sleep.Researchers at the California Institute of Technology set out to determine how and why light directly impacts sleep. Scientists wanted to know why darkness is soporific, and why brightness can disrupt deep sleep.Testing in Caltech labs revealed a light-sensitive neural protein key in maintaining the proper balance between wakefulness and sleep."Researchers had previously identified the photoreceptors in the eye that are required for the direct effect of light on wakefulness and sleep," researcher David Prober, a professor of biology at Caltech, said in a news release. "But we wanted to know how the bra...
