Novel DNA repair mechanism brings new horizons

The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. A group of researchers has discovered a new mechanism of DNA repair, which opens up new perspectives for the treatment and prevention of neurodegenerative diseases. —> Read More

Waiting to harvest after a rain enhances food safety

To protect consumers from foodborne illness, produce farmers should wait 24 hours after a rain or irrigating their fields to harvest crops, experts say. Rain or irrigation creates soil conditions that are more hospitable to Listeria monocytogenes, which when ingested may cause the human illness Listeriosis. Waiting to harvest crops reduces the risk of exposure to the pathogen, which could land on fresh produce. —> Read More

A sigh of relief was heard worldwide with today’s (July 3) successful launch to orbit of the unmanned Progress 60 cargo freighter atop a Soyuz-U booster from the Baikonur Cosmodrome, signifying the restoration of Russia’s critical cargo lifeline to the International Space Station (ISS), some two months after the devastating launch failure of the prior Progress 59 spaceship on April 28.(…)

Solar-Powered Plane Soars Over The Pacific Without A Drop Of Fuel

A solar-powered, single-pilot airplane just made aviation (and renewable energy) history, completing the 4,000-mile journey from Japan to Hawaii without stops or fossil fuel. The plane landed Friday morning at Kalaeloa Airport on the island of Oahu.

HE MADE IT! @andreborschberg just touched down in #Hawaii after a record-breaking flight! #futureisclean @bhttps://t.co/WQWsRKiCEi

The trip from Japan to Hawaii was the longest leg in the Solar Impulse 2’s ongoing trip around the world. The plane took off from Japan on Sunday afternoon, after its team determined that the weather would permit a safe passage. The crew had made a previous attempt to fly to Hawaii in late May, but that effort was aborted mid-flight due to precarious weather.

The aircraft has a maximum speed of 90 mph and only averaged around 40 mph during the flight, which means the journey took a daunting 117 hours and 52 seconds — or nearly five days. The pilot for this leg of the flight, André Borschberg, got his sleep in 20-minute naps.

By comparison, a Boeing 777, with a top speed of around 600 mph, can make the same trip in about 8.5 hours.

The Solar Impulse 2 broke a number of records with its latest flight, including longest distance for solar-powered flight, longest duration for solar-powered flight, and longest non-stop solo-pilot flight of any kind (made possible because the plane doesn’t need to stop for refueling).

“This oceanic flight to Hawaii demonstrates that if technological solutions exist to fly a plane day and night without fuel, then there is potential for these same efficient technologies to be used in our daily lives, and to achieve energy savings to —> Read More
