Raves for Science

The most incomprehensible thing about the universe is that it is comprehensible.

The roots of education are bitter, but the fruit is sweet.

Who Needs Sex?

Is there another way to mix genes besides sex?

An intriguing idea percolating through the scientific community has the power to upend a lot of biology, genetics and evolution. For that reason, scientists are treating it delicately. They are poking at the theory (because they must), but from a respectable distance. The idea, called "horizontal gene transfer," makes a terrific sci-fi premise – but it may also be true....

The Mathematics of the Internet

The Internet can be viewed as a graph, and that means you can do math with it.

The Internet is connected by links that point to other web pages that have links, etc. If you look at the links as "edges" and the pages as "nodes," you can view the Internet as a giant graph. A graph can be manipulated by the rules of mathematics and that means you can do some very clever things. This article describes one of those clever things...

A Baby’s Hair

The first animal cloning was performed with a baby's hair and tweezers.

Hans Spemann was in a foul mood as he rearranged his blankets. The beginning of the twentieth century should be vastly more exciting than this, he thought. Being swaddled in a lounge chair on the sanatorium porch was not his idea of a glorious way to ring in the new century. Getting tuberculosis was damned inconvenient, and the recovery was almost as bad as the disease. He hoped the book he had just bought would keep him from going comatose....

Observing the Deep Sky

The deeper you look into space, the more amazing the view.

People often ask, “What do you look at with that telescope?” Well, of course there are the moon and planets, not to mention all those stars. But it turns out that the sky is packed with interesting objects of many types – nebulae, clusters, galaxies, and more. We call them “Deep Sky Objects” because they physically reside far outside of our solar system, and even outside of our own Milky Way galaxy. There are thousands of such objects within reach of modest amateur telescopes, and many would argue they are the most interesting and beautiful objects to observe...

Understanding Telescopes

Buying a telescope can be overwhelming. This article will help ease the pain.

The primary goals of this article are to explain how telescopes work, what the major types and categories are, and how you can best choose a telescope for yourself or a budding young astronomer in your midst. We’ll look at some baseline principles, the major types of optical systems, mountings, manufacturers, and of course, what you can actually see and do with any given telescope...

The Mad Cow Jumps Over the Moon

Mad cow disease has led to an extraordinary new view of learning and memory.

The genesis of our national mad cow obsession is a fascinating story of adventure, discovery, ghoulishness and even happy endings. The story starts in 1955 with young Carleton Gajdusek, ten years out of Harvard, who was constantly on the lookout for new and unusual diseases. He found a remarkable one in New Guinea...

Natural Complexity

Simple chemistry can provide some surprisingly complex shapes.

Living things are so extraordinarily complex, it's hard to imagine how the happenstance mechanics of Darwinian theory could have brought them into being. We know that the natural order of things -- loosely speaking -- is to get old, break down and turn to crap. So how is it that mere protoplasm has been able to organize itself so successfully that there has been an unbroken chain of life on this planet for over 500 million years?

Electrifying News

A long-held theory comes to a shocking end.

Many young people who study science come away with the impression that all the important questions have been answered, and that it would be difficult or impossible to contribute to such a well-researched body of knowledge. But it ain't necessarily so...

We Know What You're Thinking

Scientists can see your thoughts. You won't believe what's on your mind.

You no longer have to go to Madame LeFoni's to have a mind-reading session. Scientists can read your mind too, at least a little. And what they see when they look into your mind is, well, thought-provoking...

Ears Looking at You, Kid

Some people see with their ears and hear with their eyes. These “crossed wires” may expose the workings of the brain.

Have you ever had the feeling that the person you’re talking to has a loose wire or two in their brain? Turns out, you might be right. An amazing cross-wired brain syndrome called synesthesia (for joined sensations) may explain a lot of weirdness and poetry in the world – at the same time that it sheds light on so-called normal brains...

Small Talk

Turns out, bacteria can communicate. Are they talking behind our backs?

A few years ago, Bonnie Bassler discovered something fishy about the bacteria she was studying. Actually, they were already pretty fishy, since these diminutive critters lived in the bodies of deep-sea fish and squid. Weirder still, these bacteria could glow a most beguiling moonlight blue...

Aristotle's Chickens

Aristotle came close to discovering stem cells more than two thousand years ago. Will we have to wait another two millennia for a therapy?

Aristotle strode slowly in the shade of the covered walkway, gesturing as he spoke. In his wake was an excited group of young students, straining to hear his every word. "Welcome to the Lyceum!" he shouted, spreading his arms expansively at the surrounding campus...

Time for a Colonoscopy?

If you're over 50, it's time to get this important test.

Dave Weis works as a branch manager for an industrial wholesaler in Minnesota, but on his days off, you can find him on the golf course. When he turned 50, he joined the professional senior golf tour. Together with the James E. Olson Foundation (JEO), the tour has been promoting colon cancer awareness for the last three years. Dave learned that Olson, the former chairman of AT&T, died from colorectal cancer a scant four weeks after his diagnosis. That tragic story, along with his doctor’s recommendation, was all the provocation he needed: he signed up for a colonoscopy...

A Light Touch

Because astronauts like to eat salad in space, life is getting easier for bone marrow transplant patients. An enlightening story of serendipity.

NASA is justifiably proud of its Technology Transfer Program, which spins off its space-age inventions -- from Tang and Teflon to rechargeable batteries – for use in the private sector. But they recently outdid themselves with a remarkable “healing light” that is starting to make life much easier for patients with hard-to-heal wounds, including those who have had bone marrow transplants (BMTs)...

The New Bone Marrow Transplants

Today’s Bone Marrow Transplants are saving the lives of cancer patients in unexpected ways.

By the time he was diagnosed with chronic lymphocytic leukemia, (CLL) Michael Billig’s cancer had already taken over 90 percent of his blood. His doctors lost no time in getting the 43-year-old into chemotherapy...
