How Old are Whale Sharks? Nuclear Bomb Legacy Reveals Their Age
Rutgers University-New Brunswick

Nuclear bomb tests during the Cold War in the 1950s and 1960s have helped scientists accurately estimate the age of whale sharks, the biggest fish in the seas, according to a Rutgers-led study. It’s the first time the age of this majestic species has been verified. One whale shark was an estimated 50 years old when it died, making it the oldest known of its kind. Another shark was an estimated 35 years old.

Assessing Forests From Afar
University of Delaware

A new study led by the University of Delaware’s Pinki Mondal recommends that in addition to using large swaths of coarse satellite data to evaluate forests on a national scale, it is important for countries to prioritize areas such as national parks and wildlife refuges and use finer scale data in those protected areas to make sure that they are maintaining their health and are being reported on accurately.

How Stable is Deep Ocean Circulation in Warmer Climate?
Rutgers University-New Brunswick

If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a Rutgers coauthored study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.

It’s a family thing: FSU research shows guppies help their brothers when it comes to the opposite sex
Florida State University

In a new study published by a Florida State University team, researchers found that male Trinidadian guppies observe a form of nepotism when it comes to pursuing the opposite sex. These tiny tropical fish often help their brothers in the mating process by darting in front of other males to block access to a female.

East Antarctica’s Denman Glacier has retreated almost 3 miles over last 22 years
University of California, Irvine

Irvine, Calif., March 23, 2020 – East Antarctica’s Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.
