After the genome, AstraZeneca taps 'secretome' for novel drugs

By Ben Hirschler LONDON (Reuters) - AstraZeneca is diving into the world of proteins secreted by cells - collectively known as the secretome - in the hunt for new drugs and better "cell factories" for making biotech medicines. The so-called secretome accounts for around one third of human proteins and the idea of mapping them all follows the decoding of the human genome in 2000, since when there has been a surge in scientific buzzwords ending in "ome". AstraZeneca hopes to get in on the ground floor of this opportunity through a three-year collaboration with the newly established Wallenberg Center for Protein Research in Sweden.

A new space race: satellites could test the world's climate vows

By Barbara Lewis, Richard Valdmanis and David Stanway PARIS (Reuters) - Scientists from the United States, Japan, and China are racing to perfect satellite technology that could one day measure greenhouse gas emissions from space, potentially transforming the winner into the world's first climate cop. Monitoring a single country's net emissions from above could not only become an important tool to establish whether it had met its promises to slow global warming, a point of contention at climate talks in Paris, but also help emitters to pinpoint the sources of greenhouse gases more quickly and cheaply. "We know satellite technology is evolving so that there is an increasing ability to actually tell whether countries are telling the truth." Most estimates of greenhouse gas emissions are now based on calculations of energy use and other proxy data, rather than on-the-ground measurements, leaving a huge margin of error when nations submit their figures to the United Nati…

Lost Tomb of 'Suleiman the Magnificent' Possibly Unearthed

The lost tomb of Suleiman the Magnificent, one of the greatest rulers of the Ottoman Empire, may have been unearthed in southern Hungary. In addition to his military prowess, Suleiman "the lawgiver" simplified Ottoman legal code and funded the construction of some of Istanbul's most gorgeous architecture.

SpaceX rocket aiming to fly again next week after accident

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Privately-owned Space Exploration Technologies is aiming to return its repaired Falcon 9 rocket to flight next week, following a launch accident six months ago, the company said on Thursday. For its mission on Dec. 19, the California-based SpaceX plans to launch 11 small commercial communications satellites for ORBCOMM Inc, which provides machine-to-machine messaging services, such as between retailers and shipping containers. SpaceX, which has a backlog of 60 missions worth about $8 billion, has been grounded since June 28 when its 19th Falcon 9 rocket exploded minutes after launch.

Angkor Wat Yields Astounding Buried Towers & Spiral Structure

Eight buried towers and the remains of a massive spiral structure created from sand have been discovered at Angkor Wat in Cambodia. The massive structure — almost a mile long — contains a spiral design, with several rectangular spirals that form a giant structure, archaeologists say. "This structure, which has dimensions of more than 1,500 m × 600 m (about 1 mile by 1,970 feet) is the most striking discovery associated with Angkor Wat to date.

Da Vinci Droid & Dancing Machines: Japan Convention's Coolest Bots

Leonardo da Vinci (or rather, a robot that looks a heck of a lot like the Renaissance painter and inventor) made an appearance at a robotics show in Japan last week. The humanoid da Vinci bot was on display at the Robot Exhibition 2015 (iREX), a biannual convention that opened in Tokyo on Dec. 2. With its long white beard, bright blue eyes and pensive facial expressions, the da Vinci robot really does bear a striking resemblance to the man best known as the inventor of flying machines and painter of the Mona Lisa.

Bigger Smiles, Less Hair: How Yearbook Photos Have Changed

People now may have more to smile about — at least when it comes to their yearbook photos. High school seniors today are much more likely to smile for the camera in their senior- year snaps, compared with the turn of the 20th century, new research finds. Few young women now would contemplate shellacking their hair into a beehive, instead opting for longer, more natural locks, said study lead author Shiry Ginosar, a doctoral candidate in computer science at the University of California at Berkeley.

50 Shades of Green? Environmental Attitudes Vary Widely in US

You don't have to be a nature lover to be "green." A new survey suggests that Americans' attitudes about protecting the environment aren't just linked to their love of the great outdoors. Turns out, religion and politics might be strongly tied to how people perceive environmental issues, according to the survey of 1,500 Americans who answered questions about their interactions with the natural world, their religious and political beliefs and their stance on environmental issues, such as global warming. Based on the answers, the researchers created nine distinct profiles, or "shades" of green: Only 10 percent of Americans fall into the group that the researchers labeled "outdoor greens." This group consists of staunch environmentalists who also spend a lot of time enjoying nature.

Dinosaur Blood Vessels Survived 80 Million Years Without Fossilizing

Tiny, delicate vessels that carried blood through a duck-billed dinosaur 80 million years ago never fossilized and still contain the beast's tissue, a new study finds. Researchers discovered the prize specimens on the femur (leg bone) of Brachylophosaurus canadensis, a 30-foot-long (9 meters) duck-billed dinosaur that was excavated in Montana in 2007. Now, several tests show that the specimens are the original blood vessels, making them the oldest blood vessels on record to survive with their original components, the researchers said.

IVF Puppies: First Litter Born by In Vitro Fertilization

The first-ever litter of puppies conceived through in vitro fertilization was born recently, unlocking a reproductive secret in domestic dogs that has helped researchers solve a decades-old canine biology puzzle. The findings, published online today (Dec. 9) in the journal PLOS ONE, outline the eggs-ceptional process that produced seven healthy puppies — five with two beagle parents and two with a cocker spaniel father and a beagle mother — born by scheduled caesarian section to a host female dog. In vitro ("outside the body") fertilization, also known as IVF, combines the egg and sperm in an artificial environment, creating an embryo that is then implanted in a host that carries it to full term.
