Robots are narrowing the gap with humans

Robots are gaining on us humans. Thanks to exponential increases in computer power — which is roughly doubling every two years — robots are getting smarter, more capable, more like flesh-and-blood people. Matching human skills and intelligence, however, is an enormously difficult — perhaps impossible — challenge. | 04/20/09 15:26:00 By - Robert S. Boyd

Modern life's pressures may be hastening human evolution

We're not finished yet. Even today, scientists say that human beings are continuing to evolve as our genes respond to rapid changes in the world around us. | 04/08/09 13:49:00 By - Robert S. Boyd

Fruit flies earn no respect, except among scientists

That annoying kitchen pest, the fruit fly, occupies an honored place in science and medicine, despite slurs from politicians such as Sen. John McCain and his 2008 sidekick, Sarah Palin. | 04/01/09 15:28:00 By - Robert S. Boyd

Pentagon exploring robot killers that can fire on their own

The unmanned bombers that frequently cause unintended civilian casualties in Pakistan are a step toward an even more lethal generation of robotic hunters-killers that operate with limited, if any, human control. | 03/25/09 00:06:00 By - Robert S. Boyd

Scientists harness anti-matter, ordinary matter's 'evil twin'

Tom Hanks' new movie, ``Angels and Demons,'' tells of a secret plot to blow up the Vatican and everyone inside it by using ``the most terrible weapon ever made'': anti-matter. | 03/11/09 14:59:00 By - Robert S. Boyd

Some of your body's cells have a 'license to kill'

Millions of "natural killer cells" — nature's first line of defense against cancer, viruses and other infectious microbes — are on constant patrol inside your body. | 02/17/09 13:56:00 By - Robert S. Boyd

How broken arm led scientists to genome of Neanderthals

About 38,000 years ago, a Neanderthal man living in what's now Croatia broke his left arm, forcing him to use his other arm for most tasks. That increased the mass and density of the bone in the upper right arm, and preserved his DNA for researchers — using a dentist's drill — to recover many millennia later. | 02/12/09 16:14:00 By - Robert S.

Internal clocks keep you, all living things ticking

Like kids taking apart a fine Swiss watch, scientists are laboring to understand what makes the biological clock that's inside every living creature tick. Many questions remain to be answered, however, such as how the clocks work at the level of individual molecules. | 02/05/09 14:55:00 By - Robert S. Boyd

Scientists hope satellites will solve riddle of missing CO2

Only half of the carbon emissions that world dumps into the atmosphere evey day actually stays there. Scientists, however, have never understood where the rest of it goes. Now they're hoping a pair of satellites, one from NASA, the other from Japan, will help identify the forests, pastures, crops and soil — even golf courses — that soak up carbon dioxide. | 01/29/09 17:09:00 By - Robert S.

Evolution war still rages 200 years after Darwin's birth

Two centuries after Charles Darwin's birth on Feb. 12, 1809, people still argue passionately about his theory of evolution. | 01/26/09 11:55:00 By - Robert S. Boyd

Advanced car battery makers seek juice from stimulus plan

The U.S. is struggling to catch up with China, Japan and Korea in a race to build the advanced batteries needed to power the electric cars of the future. | 01/15/09 14:29:00 By - Robert S. Boyd

Astronomers honor Galileo with a telescopic jackpot

Four hundred years after Galileo spied craters on the moon with the world's first telescope, astronomers this year will get a windfall of new and improved telescopes of unprecedented power with which to explore the universe. To honor Galielo, astronomers have declared 2009 the International Year of Astronomy to honor Galileo. | 01/08/09 15:26:00 By - Robert S. Boyd

Past inaugurations have produced many memorable moments

The inauguration of the first African-American president will long be remembered as a momentous day in history, but many past inaugurals also have had memorable moments. | 01/06/09 00:52:00 By - Robert S. Boyd

Researchers' vision: restoring sight through artificial retinas

Scientists are testing artificial retinas that they hope can restore partial sight to people who've lost their vision to the most common causes of blindness. Retinitis pigmentosa, which ruins peripheral vision, and macular degeneration, which causes a blurred or blind spot in central vision, affect millions of people, especially the elderly. | 12/29/08 14:54:00 By - Robert S.
