Japan Officials Edited Wikipedia at Work

(AP) -- Japan's Agriculture Ministry reprimanded six bureaucrats after an internal probe found they spent work hours contributing to Wikipedia on topics unrelated to farm issues - including 260 entries about cartoon robots.

Scientists can't explain algae outbreak (AP)

AP - When runaway algae killed fish and fouled beaches in the Great Lakes region decades ago, governments ordered cutbacks of phosphorus — a key algae nutrient — from laundry detergents and sewage treatment plants.

Supernovae not what they used to be

Exploding stars that light the way for research on dark energy aren`t as powerful or bright, on average, as they once were, says a new study by University of Toronto astronomers.

'Crowcam' spies on clever birds

A new technique developed by Oxford University zoologists enables researchers to ‘hitch a ride` with wild birds and witness their natural and undisturbed behaviour.

Fifty Times sharper than Hubble

M87, the central galaxy of the Virgo cluster in a distance of only 50 million light years, was observed by Yuri Kovalev from the Max Planck Institute for Radio Astronony (MPIfR) in Bonn and his colleagues with the VLBA (Very Long Baseline Array) at 2 cm wavelength. The resulting image provides details down to a resolution of one milli-arcsecond, corresponding to a linear resolution of only three...

Trick of Nature Allows Hubble and Keck to Find Tiny Galaxy

A team of astronomers at the University of California at Santa Barbara report that they have resolved a dwarf galaxy 6 billion light-years away. Weighing only 1/100 as much as our Milky Way Galaxy, the dwarf is much smaller than anything studied before in any detail at this distance.

From stick figures to artificial intelligence

Like a lot of guys his age, Brian Tanner used to be glued to a computer while he was junior-high student in Winnipeg. He especially liked to tinker around with some software that allowed him to manipulate little stick figures and create crude animations.

Google Slams FCC-Lobbyist Contacts

Just days after the investigative arm of Congress accused FCC staff members of favoring key lobbyists by disclosing nonpublic information, Google has launched its own charges of impropriety concerning talks between FCC Chair Kevin Martin and lobbyists representing Verizon Wireless. The contents of these conversations were neither disclosed in a timely fashion, as required by the FCC's own rules...

Census Of Protein Architectures Offers New View Of History Of Life

Protein architectures -- the three-dimensional structures of specific regions within proteins -- provide an extraordinary window on the history of life. Scientists compiled a global census of protein architectures, and used these relics to plot the emergence, diversification and refinement of each of the three super-kingdoms of life: archaea, bacteria and eukarya.

Left Main Coronary Artery Disease Can Double Or Triple Heart Risk In Siblings

Researchers have found that heart disease of the left main coronary artery is often an inherited condition that clusters in families. Moreover, they discovered that initially healthy siblings of a person with the condition were 2.5 times more likely to go on to develop some form of heart disease than were siblings of a patient with heart disease that did not relate to the left main coronary...

Shining A Light On Mysterious 'Dark Matter'

We've all been taught that our bodies, the Earth and in fact all matter in the universe is composed of tiny building blocks called atoms. Now imagine if this weren't the case. This mind-bending concept is at the core of the scientific research that astronomers and physicists are now pursuing.

War More Traumatic Than Tsunami

The long-running civil war in Sri Lanka is causing more mental health problems and social breakdown than the catastrophic 2004 tsunami, according to new research. The terrorisation of many Tamil communities and the destruction caused by the tsunami meant many villages were abandoned and the villagers separated.

Why Do Certain Cancers Become Resistant To Drugs?

Scientists are studying a model organism called "Dictyostelium discoideum" to better understand mechanisms of cisplatin drug sensitivity. They hope to learn why some tumors eventually build a tolerance to the common chemotherapy drug cisplatin and to identify the particular genes that can be manipulated to make treatment as effective as possible.

Can E-Mail Authentication Stop Phishing?

What do you get when Yahoo, eBay, and PayPal join forces against malware? A collaborative effort to help protect consumers against fraudulent e-mails and dangerous scams commonly called phishing attacks. A movement got underway on Thursday that gives eBay and PayPal customers who use Yahoo Mail an upper hand against fraudsters by blocking fake e-mails that claim to be coming from these popular...
