Russian Scientists Squeezed by Sanctions, Kremlin Policies

Artur Bilsky's Institute of Thermophysics recently sought to buy equipment from a Japanese company that was a routine purchase a few years ago. The request was turned down "categorically," said Bilsky, a researcher at the institute.

Hundreds of other Russian scientists are reporting similar experiences of being refused sale of scientific equipment from abroad, or seeing research papers curtly turned down by Western publications. The reason, they believe, is a combination of sanctions against Russia over its actions in Ukraine and rising hostility to Russia in the West seeping into the scientific community.

High-Tech Aerospace Exhibit Starts World Tour at Smithsonian Museum

With space shuttles now housed in history museums, innovators in aerospace are thinking of newer, better ways humans could reach space. One idea: What about a space elevator?

This real idea is one simulation that's part of a new high-tech interactive exhibition about the future of flight opening Aug. 1 at the Smithsonian's National Air and Space Museum. The exhibit also will serve as an important test case for new technologies to overhaul the popular museum with more interactives.

Japan Pledges 26% Emissions Cut by 2030

Japan, the world's sixth biggest greenhouse gas polluter, has pledged to cut emissions 26 percent from 2013 levels by 2030, a target observers judged inadequate to avert calamitous global warming.

In order to achieve this goal, nuclear energy, deeply unpopular and offline since the 2011 tsunami-induced Fukushima disaster, must provide about 20-22 percent of electricity production by then, said the country's official UN filing late Friday.

The plains are located north of Pluto's icy mountains, in the center-left of the heart shape that NASA has named "Tombaugh Regio," or the Tombaugh Region after Clyde Tombaugh, who discovered Pluto in 1930.

Solar Plane Pilots: Rapid Climb, Descent Stressed Batteries

The pilots of a grounded solar-powered airplane say they put too much stress on the batteries of their aircraft as they were leaving Japan for a five-day record-breaking flight to Hawaii.

The pilots then discovered they had too much insulation around the batteries for them to adequately cool down during the flight through tropical skies.

Report: Hong Kong Ivory Trade 'Major Threat' to Elephant Survival

Rampant illegal trading in ivory in Hong Kong is pushing elephants towards extinction, conservationists said Thursday, reporting more ivory items on sale there than in any other city.

The sale of ivory items from government-registered stockpiles predating the 1990 ban is allowed for domestic use in Hong Kong, but the report finds tusks from recently slaughtered elephants are being passed off as old ivory on a huge scale.
