Are seagulls killing whales in Patagonia?

It sounds ludicrous, but it could just be true: scientists say seagulls may be responsible for hundreds of southern right whale moralities off the Argentine coastline. Since 2003, scientists have documented the deaths of 605 southern right whales (Eubalaena australis) near Península Valdés which the whales use as a nursery. Notably, 88 percent of these were newborn calves. The death rate is so high that researchers now fear for the whales’ long-term survival.   Original post on mongabay.com    Comments on reddit.com

Einstein’s gravity theory passes toughest test yet: Bizarre binary star system pushes study of relativity to new limits

(Phys.org) —A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive neutron star in orbit with a companion white dwarf star puts competing theories of gravity to…   Original post on phys.org    Comments on reddit.com   

Last 30 years were the warmest in the last 1,400 years

From 1971 to 2000, the world’s land areas were the warmest they have been in at least 1,400 years, according to a new study in Nature Geoscience. The massive new study, involving 80 researchers from around the world with the Past Global Changes (PAGES) group, is the first to look at continental temperature changes over two thousand years, providing insights into regional climatic changes from the Roman Empire to the modern day. According to the data, Earth’s land masses were generally cooling until anthropogenic climate change reversed the long-term pattern in the late-19th Century.   Original post on mongabay.com    Comments on reddit.com
