Science Glance
For five years now, fans of female scientists have set aside the date of Oct. 15th to recognize their accomplishments, naming the effort after the remarkable Ada Lovelace, a 19th century woman who began her life as the only child of the poet Lord Byron with his wife. Lovelace then went on to write the first algorithm intended to be used by a machine, rendering her, in effect, the world's first computer programmer.
The early years of celebrating Lovelace and other women saw requests for people around the world to blog about women in science. But many of the celebrations held across 10 countries for Tuesday's Ada Lovelace Day will be like the one planned at Brown University, where organizers are holding an "edit-a-thon.'' Participants will be asked to make new Wikipedia entries on women in the fields of science, technology, engineering and mathematics, also known as the STEM fields.

What archaeology tells us about the Bible
For the past 20 years, a battle has been waged with spades and scientific tracts over just how mighty David and the Israelites were. A string of archaeologists and Bible scholars, building on critical scholarship from the 1970s and '80s, has argued that David and his son Solomon were the product of a literary tradition that at best exaggerated their rule and perhaps fabricated their existence altogether.
For some, the finds at Qeiyafa have tilted the evidence against such skeptical views of the Bible. Garfinkel says his work here bolsters the argument for a regional government at the time of David – with fortified cities, central taxation, international trade, and distinct religious traditions in the Judean hills. He says it refutes the portrayal by other scholars of an agrarian society in which David was nothing more than a "Bedouin sheikh in a tent."
Lonely planet without a star discovered wandering our galaxy
An exotic young planet free-floating through the Milky Way galaxy rather than orbiting any star is practically a newborn in cosmic terms, astronomers say.
Dubbed PSO J318.5-22, the planet without a host star is 80 light-years away from Earth and has a mass only six times that of Jupiter. It formed a mere 12 million years ago, researchers said -- a newborn in planet lifetimes.
Scientists who took chemistry into cyberspace win Nobel Prize
Three U.S. scientists won the Nobel chemistry prize on Wednesday for pioneering work on computer programs that simulate complex chemical processes and have revolutionized research in areas from drugs to solar energy.
The Royal Swedish Academy of Sciences, awarding the prize of 8 million crowns ($1.25 million) to Martin Karplus, Michael Levitt and Arieh Warshel, said their work had effectively taken chemistry into cyberspace. Long gone were the days of modeling reactions using plastic balls and sticks.
Work on 'cell traffic' and disease triggers wins Nobel prize
Three U.S.-based scientists won the Nobel medicine prize on Monday for plotting how vital materials such as hormones and brain chemicals are transported within cells and secreted to act on the body, giving insight into diseases such as diabetes and Alzheimer's.
Americans James Rothman, 62, Randy Schekman, 64, and German-born Thomas Suedhof, 57, separately mapped out one of the body's critical networks that uses tiny bubbles known as vesicles to ferry chemicals such as insulin within cells.
New shape-shifting metals discovered
A new shape-changing metal crystal is reported in the journal Nature, by scientists at University of Minnesota. It is the prototype of a new family of smart materials that could be used in applications ranging from space vehicles to electronics to jet engines.
Called a "martensite", the crystal has two different arrangements of atoms, switching seamlessly between them. It can change shape tens of thousands of times when heated and cooled without degrading, unlike existing technology.
US scientists boycott Nasa conference over China ban
Nasa is facing an extraordinary backlash from US researchers after it emerged that the space agency has banned Chinese scientists, including those working at US institutions, from a conference on grounds of national security.
Nasa officials rejected applications from Chinese nationals who hoped to attend the meeting at the agency's Ames research centre in California next month citing a law, passed in March, which prohibits anyone from China setting foot in a Nasa building.
