Rocket Lab launches Boston University’s magnetosphere experiment

Rocket Lab launches Boston University’s magnetosphere experiment

Science
June 13 (UPI) -- A rocket launched five small satellites into orbit from New Zealand early Saturday morning, including a Boston University experiment to measure solar winds and the Earth's magnetosphere. California-based Rocket Labs, which owns the New Zealand launch site on the Mahia Peninsula, lofted the satellites aboard a company Electron rocket at 1:12 a.m. EDT. The launch was delayed slightly by a cumulus cloud above the pad. Advertisement The launch had been postponed twice -- once in May because of travel restrictions amid the coronavirus pandemic and again Thursday due to high winds. Boston University's experiment, the ANDESITE CubeSat, consists of one satellite the size of a toaster oven that is carrying eight tiny satellites inside. They will be released to form a network that ...
Barcelona’s car-free smart city experiment

Barcelona’s car-free smart city experiment

Technology
In the centre of bustling and busy Barcelona there is unusual quiet: just the babble of children playing in a small playground and the sound of the birds.There is virtually no traffic and the space where cars would have parked is given over to play areas, trees and even a running track.Superblocks is a radical plan to reclaim the streets from the noise and pollution of traffic, one that could save hundreds of lives that might otherwise be lost because of heavily polluted air. It also hopes to act as a blueprint for other cities.There are just six superblocks so far, but Barcelona plans hundreds of others. They are made up of nine existing blocks joined together into an area which bans all but essential vehicles - which are limite...

Once-a-month birth control pill? Experiment works in animals

Health
Scientists are developing a once-a-month birth control pill that would gradually release the drug over the course of weeksBy LAURAN NEERGAARD AP Medical WriterDecember 4, 2019, 10:06 PM4 min read Birth control pills work great if women remember to take them every day but missing doses can mean a surprise pregnancy. Now scientists have figured out how to pack a month’s supply into one capsule. The trick: A tiny star-shaped gadget that unfolds in the stomach and gradually releases the drug. The experimental capsule is still years away from drugstores, but researchers reported Wednesday that it worked as designed in a key test in animals. The Bill and Melinda Gates Foundation is investing $ 13 million for further development of the once-a-month pill, in hopes of eventually improving family p...
Chernobyl: The end of a three-decade experiment

Chernobyl: The end of a three-decade experiment

Science
Since the explosion at the Chernobyl nuclear power plant in 1986, an area of more than 4,000 square kilometres has been abandoned. That could be about to change, as Victoria Gill discovered during a week-long trip to the exclusion zone. "This place is more than half of my life," says Gennady Laptev. The broad-shouldered Ukrainian scientist is smiling wistfully as we stand on the now dry ground of what was Chernobyl nuclear power plant's cooling pond. "I was only 25 when I started my work here as a liquidator. Now, I'm almost 60." There were thousands of liquidators - workers who came here as part of the mammoth, dangerous clean-up operation following the 1986 explosion. The worst nuclear accident in history. Gennady shows me a coffee table-sized platform...
Experiment considers chemical composition of prehistoric ocean

Experiment considers chemical composition of prehistoric ocean

Science
March 9 (UPI) -- How can you study conditions inside Earth's ancient ocean? You recreate it, but on a much smaller scale.Scientists at Iowa State University did just that, mixing up a biochemical concoction designed to replicate the ocean waters of the Archean Era, 2.5 billion years ago, inside a graduated cylinder.The experiment is helping scientists better understand the conditions under which iron-rich sedimentary rocks form.Until now, scientists believed iron-rich sedimentary rocks form under anoxic conditions, in ocean waters with limited amounts of oxygen. Chemical signatures inside rocks can help researchers better understand the changing chemical conditions in ancient oceans.Iron-rich sedimentary rocks have traditionally served as a proxy for the ocean as it was before cyanobacteri...
