Scientists outline long-term sea-level rise in response to warming of planet

Posted: 15 Jul 2013 01:48 PM PDT

A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms. This is one of the first analyses to combine four major contributors to potential sea level rise into a collective estimate, and compare it with evidence of past sea-level responses to global temperature changes.

Nesting Gulf of Mexico loggerhead turtles face offshore risks

Posted: 15 Jul 2013 11:18 AM PDT

Threatened loggerhead sea turtles in the northern Gulf of Mexico can travel distances up to several hundred miles and visit offshore habitats between nesting events in a single season, taking them through waters impacted by oil and fishing industries.

Distorted GPS signals reveal hurricane wind speeds

Researchers have found a way to do something completely different with GPS: Measure and map the wind speeds of hurricanes. The new technique could help meteorologists better predict storm severity, how storms form, and where they might be headed.

Black-legged ticks linked to encephalitis in New York state

Posted: 15 Jul 2013 06:12 AM PDT

The number of tick-borne illnesses reported to the U.S. Centers for Disease Control and Prevention is on the rise. Lyme disease leads the pack, with some 35,000 cases reported annually. In the Northeast, the black-legged ticks that spread Lyme disease also infect people with other maladies, among them anaplasmosis, babesiosis, and — now — Powassan encephalitis.

Phytoplankton social mixers: Tiny ocean plants use turbulence for travel to social gatherings

Scientists have shown that the motility of phytoplankton also helps them determine their fate in ocean turbulence.

New retroviruses found in polar bear ‘Knut’ and panda ‘Bao Bao’

Posted: 15 Jul 2013 04:03 AM PDT

Endogenous retroviruses (ERVs) are viruses that at some point in the past inserted themselves into the nuclear genome of a host’s germ cell. Once integrated in a germ cell the virus would be passed on from one generation to the next and the endogenous retroviral genome would therefore be inherited to new species that evolve from the original host.
