(Reuters) - A Swiss man attempting to circumnavigate the globe with an aircraft powered only by the sun's energy landed in Hawaii on Friday, after a record-breaking five-day nonstop solo flight across the Pacific Ocean from Japan. The Solar Impulse 2 is the first aircraft to fly day and night without any fuel. Pilot Andre Borschberg's 120-hour voyage shattered the 76-hour record for nonstop flight by late American adventurer Steve Fossett in 2006 on the Virgin Atlantic Global Flyer.
By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A Russian Soyuz rocket blasted off on Friday to deliver a cargo ship loaded with food, water and equipment to the International Space Station, breaking a string of launch failures, a NASA TV broadcast showed. The Progress capsule, carrying more than three tons (2,700 kg) of supplies, was expected to reach the orbiting outpost on Sunday following launch at 12:55 a.m. EDT from the Baikonur Cosmodrome in Kazakhstan. ?All of the systems on the Progress (are) in excellent shape,? said NASA launch commentator Rob Navias.
By Will Dunham WASHINGTON (Reuters) - Woolly mammoths spent their lives enduring extreme Arctic conditions including frigid temperatures, an arid environment and the relentless cycle of dark winters and bright summers. An exhaustive genetic analysis of these bygone Ice Age giants and their living cousins, Asian and African elephants, has revealed a slew of genetic adaptations that enabled woolly mammoths to thrive for eons in such adverse circumstances. The study, published on Thursday in the journal Cell Reports, compared the genomes of two mammoths whose remains were found in permafrost in northeastern Siberia, one 18,500 years old and the other 60,000 years old, with genomes of three Asian elephants and one African elephant.
By Irene Klotz and Andrea Shalal CAPE CANAVERAL, Fla./WASHINGTON (Reuters) - SpaceX can compete to launch a U.S. Global Positioning System satellite despite a Falcon 9 rocket accident this weekend, the Air Force said on Wednesday. ?SpaceX remains certified and can compete for the upcoming GPS III launch service,? Lt. General Samuel Greaves, who heads the Air Force?s Space and Missile Systems Center, wrote in an email to Reuters. The Air Force plans to release a solicitation for launch service proposals this month, the first time SpaceX, which is owned and operated by technology entrepreneur Elon Musk, will be eligible to compete against United Launch Alliance (ULA).
By Will Dunham WASHINGTON (Reuters) - With a little help from Clint Eastwood, Jennifer Aniston and Josh Brolin - or at least photos of them - scientists have gained a new understanding of how memories of everyday events are formed in the brain. Researchers said on Wednesday a study involving people with electrodes implanted in their brains has shown that individual neurons in a region called the medial temporal lobe play a central role in swiftly forming these memories. The devices also enabled the researchers to pinpoint individual neurons that encoded memories.
New photographs of fluorescent sea creatures ? including bright orange animals that resemble feather dusters with long, skinny handles, and spongy, neon-pink anemones ? on the Arctic seafloor could help researchers determine how much methane, a potent greenhouse gas, will make its way to the atmosphere and contribute to climate change. It's amazing," said Guiliana Panieri, a scientist on the photo-taking expedition and a professor in environment and climate at The Arctic University of Norway. The colorful sea creatures live near methane seeps, or cracks in the ocean floor that naturally release methane.
