The Macintosh - the first to bear the name - turns 25 on 24 January. The machine debuted in 1984 and kicked off a product line that were Apple's flagship computers for many years.

The Macintosh helped popularize the combination of graphical interface and mouse that is ubiquitous today. It had a revolutionary all-in-one design, and crucially, used a graphical user interface to navigate around, rather than text commands. This enabled the Apple Macintosh to cross the species barrier – everyday users could now use the computer, rather than just geeks au fait with scripting and coding. Indeed, the $2,495 price tag was perhaps the only barrier to entry.

The mouse input system and simple GUI enabled users to carry out a range of tasks that had been impossible on other computers. The Apple Macintosh came bundled with two software programs, MacWrite and MacPaint, signalling the birth of word processing and desktop publishing. With just 128KB of memory and a sloth-like 8MHz processor, the Apple Macintosh is woefully underpowered by today’s standards, but was cutting edge at the time.  read more »

WASHINGTON - President Barack Obama was inaugurated yesterday as the 44th president of the United States, seizing the historic moment to invoke the "price and the promise of citizenship" and demand the participation of all Americans in restoring the country to greatness. He took the oath of office on Abraham Lincoln's Bible before a sea of more than 1 million people that stretched from the Capitol building to the Lincoln Memorial. He struck a solemn tone in warning of the challenges and sacrifices that lie ahead. Comparing the economic crisis and fight against terrorism to the trials faced by the Founding Fathers, Obama implored his fellow citizens to join him "in the work of remaking America."

"On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord," Obama said, his voice reverberating throughout the National Mall. "Let it be said by our children's children that when we were tested, we refused to let this journey end - that we did not turn back, nor did we falter."  read more »

The fantasy of spy novels and science fiction films is at last becoming reality with a vehicle that can turn from car to aircraft in 15 seconds

It is the ultimate off-roader and it is coming to an airstrip near you. The Terrafugia Transition is a two-seater plane that at the touch of a button converts into a road-legal car. It takes its maiden flight next month and is scheduled to hit the showrooms by next year. “It’s like a little Transformer,” says Carl Dietrich, the Terrafugia boss, proudly. “This is the first really integrated design where the wings fold up automatically and all the parts are in one vehicle. All we have is one simple folding wing, and that means the Transition takes just 15 seconds to switch between flying and driving.”

The Terrafugia Transition is a light sport airplane with four wheels and foldable wings that span 27.5ft when extended. It can soar up through the skies just like a regular aircraft then land on the ground, fold up its two wings and drive down the road at highway speeds. Measuring 19 feet long, it has an airborne range of 460 miles and can cruise at 115mph. According to early reports, the plane uses unleaded gasoline - no rocket fuels necessary. It runs via the 100 horsepower four-stroke Rotax 912S engine.  read more »

For South African-born explorer Mike Horn, 42, navigating in sub-zero temperatures requires basic tools: chocolate for energy and mucus for wind-block. Horn has circumnavigated the Arctic Circle solo, circled the globe along the equator without motorized transport and completed the first-ever night expedition to the North Pole, without dogs and frequently swimming along the way.

Back in 2002, Horn's expedition around the Arctic Circle involved skiing, sailing, kayaking and trekking in temperatures as low as -76 F (-60 C). This year, Horn embarks on his most ambitious expedition to date - Pangaea.  read more »

It turns out that our solar system is moving nearly 100,000 m.p.h. faster than previously thought — revolving around the center of the Milky Way at 568,000 m.p.h., announced Mark Reid of the Harvard-Smithsonian Center for Astrophysics on Monday at the American Astronomical Society's conference in Long Beach, Calif. Since velocity is related to mass, the 15% increase in solar-system speed translates into a near doubling of mass of the Milky Way, according to Reid's group — and all of that newfound bulk is composed of dark matter.

Original estimates of the solar system's speed were based on what Reid calls "one- dimensional velocity" obtained solely from Doppler shifts. "Now," he says, "we have three-dimensional velocity and more exact measurements" — a huge advancement in the field. The findings debunk the notion that the Milky Way is a little-sister galaxy to her neighbor Andromeda. "They're more like fraternal twins," Reid says. And the fact that they are of equal size increases the likelihood that the two will someday collide.

But humans needn't flee the galaxy anytime soon. First, there's so much room between stars that Earth likely wouldn't feel any effects of a galactic collision, though our constellations would certainly change. And second, a crash is still about 3 billion to 5 billion years away, by which time our sun will have transformed into a red giant and turned the Earth into a smidgen of charred dust.  read more »

Samuel F.B. Morse
It was on this day, January 6, in the year 1838 that Samuel Morse first demonstrated the electric telegraph. The telegraph was perhaps the single largest step forward in telecommunication history, in that it allowed messages to be sent electronically for the first time. The telegraph was key in settling the west, and served as the basis for modern communication methods.

"Science and art are not opposed" - Samuel Morse.

Samuel F.B. Morse led a superbly rendered life as a painter, sculptor, professor and photographer. He became best known, however, for his invention of the telegraph. Morse used the invention of the electromagnet in 1825 to develop a way to communicate virtually instantly over long distances using his own code.

Early days

Samuel Finley Breese Morse was born on April 27, 1791, in Charlestown, just outside of Boston, Massachusetts. He was the son of Jedidiah Morse, a pastor well known for his knowledge of geography. Samuel showed an interest in electricity, but his love was art. His father opposed art as a career - not realizing how determined Samuel was to paint.

The US space agency's (NASA) Mars rovers are celebrating a remarkable five years on the Red Planet. The first robot, named Spirit, landed on 3 January, 2004, followed by its twin, Opportunity, 21 days later. Their longevity in the freezing Martian conditions has surprised everyone.

The unmanned rovers Spirit and Opportunity are showing serious signs of wear after an astounding five years roaming Mars, U.S. space agency officials say. Scientists initially thought the remote-controlled machines would last only three months in Mars' freezing climate, said John Callas, rover project manager at the National Aeronautics and Space Administration's Jet Propulsion laboratory in Pasadena, Calif.

"These rovers are incredibly resilient considering the extreme environment the hardware experiences every day," Callas said, noting information sent by the rovers have proved water existed on Mars billions of years ago.  read more »
