The news that U.S. scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the announcement of the creation of Dolly the sheep in 1997.

Scientists have discovered water that has been trapped in rock for more than a billion years. The water might contain microbes that evolved independently from the surface world, and it's a finding that gives new hope to the search for life on other planets.

The water samples came from holes drilled by gold miners near the small town of Timmins, Ontario, about 350 miles north of Toronto. Deep in the Canadian bedrock, miners drill holes and collect samples. Sometimes they hit pay dirt; sometimes they hit water, which seeps out from tiny crevices in the rock.

It turns out that the desire to speak with Apple CEO Tim Cook, along with $610,000, will buy you a cup of coffee. That's the winning bid offered in a charity auction for up to an hour of Cook's time.

As we reported last month, the chance to grab coffee with Cook at Apple's headquarters zoomed past the suggested value of $50,000 set at the Charitybuzz auction site, rising to more than $600,000 in just three days.

By the end of the century, the birthplace of America may be underwater.

The first successful English colony in America was at Jamestown, Va., a swampy island in the Chesapeake Bay. The colony endured for almost a century, and remnants of the place still exist. You can go there and see the ruins. You can walk where Capt. John Smith and Pocahontas walked. But Jamestown is now threatened by rising sea levels that scientists say could submerge the island by century's end.

Solved! A bee-buzzing, honey-licking 2,000-year-old mystery that begins here, with this beehive. Look at the honeycomb in the photo and ask yourself: (I know you've been wondering this all your life, but have been too shy to ask out loud ... ) Why is every cell in this honeycomb a hexagon?

Bees, after all, could build honeycombs from rectangles or squares or triangles ...

But for some reason, bees choose hexagons. Always hexagons.

Heather Dewey-Hagborg was sitting in a therapy session a while ago and noticed a painting on the wall. The glass on the frame was cracked, and lodged in the crack was a single hair. She couldn't take her eyes off it.

"I just became obsessed with thinking about whose hair that was, and what they might look like, and what they might be like," she says.

There will be a special attraction for deaf people in theaters nationwide soon. By the end of this month, Regal Cinemas plans to have distributed closed-captioning glasses to 6,000 screens across the country.

Beekeepers In Massachusetts are taking the mission to save the bees into their own hands.

There has been a dramatic disappearance of honeybees across the U.S. since 2006. A recent U.S. Department of Agriculture report blamed a combination of problems, including mites, disease, poor nutrition and pesticides.

Climate scientists have a good reason to want to get away from it all. To get an accurate picture of the amount of carbon dioxide in the Earth's atmosphere, you have to find places where the numbers won't be distorted by cities or factories or even lots of vegetation that can have a major local impact on CO2 concentrations.

At about 300 colleges across the country, young activists worried about climate change are borrowing a strategy that students successfully used in decades past. In the 1980s, students enraged about South Africa's racist Apartheid regime got their schools to drop stocks in companies that did business with that government. In the 1990s, students pressured their schools to divest Big Tobacco.

This time, the student activists are targeting a mainstay of the economy: large oil and coal companies.

In 1961, Mel Brooks and Carl Reiner came up with some basic theories of caveman linguistics in their 2,000-Year-Old Man skit. Most of them had to do with rocks, as in, "What are you doing with that rock there?"

Now, a professor in England has questioned the validity of the famous caveman's rock-centric theories. And Mark Pagel of the University of Reading is reaching even further back, to the time of the 15,000-year-old man.

What you are about to see — and I'm not making this up — is a moth driving a car.

YouTube is expected to announce in the coming days that it will launch paid subscription channels, a first for the online video platform that's been around since 2005. But, with the growing number of subscription services available for entertainment, shopping and news, some consumers say they're reaching digital subscription overload.

When Microsoft introduced Windows 8 last year, the software giant billed the new operating system as one of the most critical releases in its history. The system would bridge the gap between personal computers and the fast-growing mobile world of tablets and smartphones.

But this week, the company sent signals that it might soon alter Windows 8 to address some early criticism of the operating system.

The origin of some of the words we use today goes back much further than scientists once thought, suggesting an Ice Age-era proto-language that spawned many of the world's contemporary linguistic groups, according to a new study by a group of U.K.-based scientists.

According to a new survey of America's beekeepers, almost a third of the country's honeybee colonies did not make it through the winter.

That's been the case, in fact, almost every year since the U.S. Department of Agriculture began this annual survey, six years ago.

Over the past six years, on average, 30 percent of all the honeybee colonies in the U.S. died off over the winter. The worst year was five years ago. Last year was the best: Just 22 percent of the colonies died.

Some things you just count on. Like if we ever meet a space alien, it should have eyes (and maybe a head). Like somewhere out there, there are planets like ours. Like we have an ordinary solar system — "ordinary" because you know what it looks like ...

It's got a sun in the middle, little planets on the inside, bigger ones farther out. That's what most of them should look like, no?

American companies that do business with China make good money. They also lose a lot of money there to cyberthieves, who routinely hack into the computers of the U.S. firms and steal their trade and technology secrets.

Computers were created to be useful tools, but all too often it's still a chore to get technology to do our bidding.

The economy may be on the rebound, but many cultural institutions are still struggling to regain their financial footing. That's especially true for one of the country's most recognized museums — the Field Museum of Natural History in Chicago. Known internationally for its research as well as its exhibits, the Field Museum must pay off millions in bond debt — and toe an ethical line as it does.

The Earth's wettest regions are likely to get wetter while the most arid will get drier due to warming of the atmosphere caused by increased levels of carbon dioxide, according to a new NASA analysis of more than a dozen climate models.

A smartphone can tell you where to get a cup of coffee, but it can't go get the coffee for you. Engineers would like to build little machines that can do stuff. They would be useful for a lot more than coffee, if we could figure out how to make them work.

But the rules of mechanics change at small scales. Friction becomes dominant; turbulence can upend a small airplane.

Galactic poet?

Here's how to become famous.

Send your work to Mars!

NASA is raising awareness for its upcoming launch of the Mars Atmosphere and Volatile Evolution spacecraft with its Going to Mars project. The MAVEN spacecraft is scheduled for launch this November, to study the Red Planet's upper atmosphere; the craft will examine why Mars lost its atmosphere, and how that catastrophe affected the history of water there.

Ask most folks who came up with the theory of evolution, and they'll tell you it was Charles Darwin.

In fact, Alfred Russel Wallace, another British naturalist, was a co-discoverer of the theory — though Darwin has gotten most of the credit. Wallace died 100 years ago this year.

NASA is calling it "The Rose." By any other name, it's a mammoth storm on Saturn's north pole. Its eye spans an estimated 1,250 miles — 20 times the size of an average hurricane's eye on Earth. Winds in the Saturn storm's eye wall are believed to be four times as fast.

The stunning image of the spinning vortex was given "false colors" to emphasize low clouds (in red) versus high clouds (in green). NASA estimates that the clouds at the outer edge are moving at up to 330 miles per hour.

As the inventor of the telephone, Alexander Graham Bell is credited with bringing countless voices to our ears. And now, for the first time, here he is imploring us to hear his own voice:

The sound is scratchy. You have to strain to decipher it, but the words are clear. They're from Bell's lips, recorded in 1885 but unveiled just last week by the Smithsonian.

"It lets us know what the past was really like. It fills in a gap for people," says Shari Stout, collections manager at the Smithsonian's National Museum of American History.

We all deserve a break from the past week's news. This NASA video could be just the right thing.

Last year's drought wreaked havoc on farmers' fields in much of the Midwest, cutting crop yields and forcing livestock producers to cull their herds. This spring, the rain that farmers needed so badly in 2012 has finally returned. But maybe too much, and at the wrong time.

It's almost the end of April, which is prime time to plant corn. But farmers need a break in the rain so they can get this year's crops in the ground and try to lock in good yields at harvest.

Scientists can't just agree to disagree. It's not because we are stubborn or ornery (OK, maybe we are). It's because the whole point of science is to establish "public knowledge" — an understanding of the cosmos on which we can all agree. That is why there is trouble brewing at the beginning of the Universe.

There is a number, the Hubble Constant, that's fundamental to the study of the cosmos. The problem is, different folks are finding different values for that number and no one yet knows what that means.
