Air pollution cuts three years off lifespans in northern China

There are currently an estimated 4.5 billion people around the world exposed to levels of particulate air pollution that are at least twice what the World Health Organization considers safe. Yet the impact of sustained exposure to pollution on a person’s life expectancy has largely remained a vexingly unanswered question—until now.

WHY YOUR ANCESTORS WOULD HAVE ACED THE LONG JUMP

A 52-million-year-old ankle fossil suggests our prehuman ancestors were high-flying acrobats.

These first primates spent most of their time in the trees rather than on the ground, but just how nimble they were as they moved around in the treetops has been a topic of dispute.

For years, scientists thought the ancestors of today’s humans, monkeys, lemurs and apes were relatively slow and deliberate animals, using their grasping hands and feet to creep along small twigs and branches to stalk insects or find flowers and fruits.

Ancient wetlands offer window into climate change

The work – led by the University of Adelaide, and involving scientists from the Queensland Government, and members of the local community – has uncovered what the researchers describe as a "treasure trove" of ancient wetlands on Queensland's North Stradbroke Island (known to Indigenous communities as Minjerribah), some dating as old as 200,000 years ago.

NASA Flights Map Summer Melt of Greenland Land Ice

Operation IceBridge is flying in Greenland to measure how much ice has melted over the course of the summer from the ice sheet. The flights, which began on Aug. 25 and will go on until Sept. 21, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet.

MIT map offers real-time, crowd-sourced flood reporting during Hurricane Irma

As Hurricane Irma bears down on the U.S., the MIT Urban Risk Lab has launched a free, open-source platform that will help residents and government officials track flooding in Broward County, Florida. The platform, RiskMap.us, is being piloted to enable both residents and emergency managers to obtain better information on flooding conditions in near-real time.

Urban Climate Change

Southern cities such as Houston and Tampa — which faced the wrath of hurricanes Harvey and Irma, respectively — may not be the only urban environments vulnerable to extreme weather. Northern cities also face the potential for flooding as global temperatures continue to warm.

How Openings in Antarctic Sea Ice Affect Worldwide Climate

In a new analysis of climate models, researchers reveal the significant global effects that these seemingly anomalous polynyas can have.

Study: The USA threatened by more frequent flooding

Researchers at the University of Bonn with US colleagues show that the East Coast of the USA is slowly sinking into the sea.

How Liver Cancer Develops

Liver cancer is the second-leading cause of cancer-related death and represents the fastest rising cancer worldwide. In most cases, the tumor develops in patients with chronic liver disease. Such diseases include chronic infections with hepatitis viruses or a so-called fatty liver due to nutritional or genetically caused lipometabolic disorders or an excessive consumption of alcohol.

NASA Analyzes Hurricane Jose's Hidden Cloud-Filled Eye

NASA satellite imagery provided a couple of views of Hurricane Jose's cloud-filled eye allowing forecasters to see that it still existed. NASA-NOAA's Suomi NPP satellite provided a visible look at the storm, while the GPM satellite provided a deeper look under the high clouds that were covering the eye.
