Painless Laser Device Could Spot Early Signs Of Disease

Photo: Fibre-optic probes could use lasers to distinguish between cancerous, pre-cancerous and healthy cells

From The BBC:

Portable devices with painless laser beams could soon replace X-rays as a non-invasive way to diagnose disease.

Researchers say that the technique could become widely available in about five years.

The method, called Raman spectroscopy, could help spot the early signs of breast cancer, tooth decay and osteoporosis.

Scientists believe that the technology would make the diagnosis of illnesses faster, cheaper and more accurate.

BIRMINGHAM: Lack of exercise is not the cause of the obesity epidemic, said biologist John Speakman, who has found that we do not exercise less nowadays.

Speakman, from the University of Aberdeen, has collected data showing that too much food, not too little exercise has caused us to pile on the pounds.

Mars Orbiter Back Up And Running Again Following Computer Glitch

This artist's concept of the Mars Reconnaissance Orbiter from 2006 features the spacecraft's main bus facing down, toward the red planet. The large silver circular feature above the spacecraft bus is the high-gain antenna, the spacecraft's main means of communicating with both Earth and other spacecraft. NASA/JPL

From Christian Science Monitor:

Mars orbiter spontaneously rebooted itself and stopped gathering information last week. However, last Saturday, the Mars orbiter began collecting data again and appears to be back on track, high above the Red Planet.

A powerful NASA spacecraft around Mars has bounced back yet again Saturday, resuming its study of the Red Planet three days after a recurring computer glitch temporarily waylaid its mission.

The Mars Reconnaissance Orbiter started gathering science data again on Sept. 18, NASA officials announced. On Sept. 15, the orbiter put itself into precautionary "safe mode" — a sort of spacecraft hibernation — after spontaneously rebooting for unknown reasons.

Mankind's First Genocide?

New Discoveries Hint At 5,500 Year Old Fratricide At Hamoukar, Syria -- The Independent

Five years ago, archaeologists found the “earliest evidence for large scale organized warfare in the Mesopotamian world.” Using slings and clay bullets a – likely Uruk – army took over the city of Hamoukar, burning it down in the process. Now, new discoveries at a nearby settlement shed more light on the 3500 BC battle – and raise more questions. If the invading army was from Uruk, did they kill their own people? If so, why?

Hamoukar is a city that flourished in northern Syria since at least 4000 BC. They traded in obsidian and in later times copper working became increasingly important to the city’s economy. Thousands of clay sealings – once used to lock doors or containers and impressed with stamp seals – were found at the ancient site. They tell of a bureaucratic system that was almost as complex as our own.

NASA Budget Likely to Remain In Limbo Until After Election Day, Lawmakers Say

From Popular Science:

Apparently, space doesn’t sell in an election year. Lawmakers are saying Congress is unlikely to make any spending decisions about NASA until after November 2, according to several reports.

Congress has been debating the space agency’s future in fits and starts since the beginning of the year, when President Obama first proposed shifting its priorities. Lawmakers balked at his plans and offered their own budget suggestions, which have been bandied about through the summer. Still, competing House and Senate bills remain in play, and they’re unlikely to get resolved in the next two weeks, when Congress goes on fall break to concentrate on the midterm elections.

Scientists have developed a computer chip that could pave the way for a new generation of powerful 'quantum' computers.

The photonic chip, built by scientists from Bristol’s Centre for Quantum Photonics, uses light rather than electricity to pass information.

The breakthrough could lead to 'quantum' computers capable of performing complex calculations and simulations that are impossible for today's computers.

Aurora Saturnalis: Halos At The Poles Of The Ringed Planet

From New Scientist:

Saturn was already the solar system's undisputed lord of the rings. Now newly processed images from the Cassini spacecraft are revealing previously unseen halos of infrared auroral light above the planet's poles.

Auroras on Saturn form like those on Earth, when charged particles in the solar wind stream down the planet's magnetic field towards its poles, where they excite gas in the upper atmosphere to glow. Some auroras on the ringed planet are also triggered when some of its moons, which are electrically conducting, move through the charged gas surrounding Saturn.

How To Do (Almost) Everything With A Kindle 3

From Gadget Lab:

Amazon’s Kindle can do a lot more than just buy and read Amazon-sold e-books. This is often a surprise. I usually wind up in conversations where someone says “I’d like to try a Kindle, but it can’t _______.” Usually, it can.

I was actually surprised when I bought my Kindle not just by how much it could do, but by how well it did it. The Kindle suffers from two things: 1) it’s never going to do everything that a full-fledged computer or even a color touchscreen tablet can do; and 2) the Kindle 3 has improved on a whole slew of features that were either poorly implemented in or entirely absent from earlier iterations of the Kindle.

Neandertals Blasted Out Of Existence, Archaeologists Propose

TRINKETS OF SURVIVAL Human-made items, such as these pendants fashioned from animals' teeth, appeared in a Russian cave shortly after volcanic eruptions around 40,000 years ago wiped out Neandertal populations in the area, researchers say.Golovanova et al.

From Science News:

Modern humans may have thrived thanks to geographic luck, not wits.

Neandertals didn’t get dumped on prehistory’s ash heap — it got dumped on them. At least three volcanic eruptions about 40,000 years ago devastated Neandertals’ western Asian and European homelands, spurring a rapid demise of these humanlike hominids, says a team led by archaeologist Liubov Golovanova of the ANO Laboratory of Prehistory in St. Petersburg, Russia.

Robots On TV: Rescue Bot Knows, Um, What You Mean

From New Scientist:

A robot that can understand plain English and manage a complicated to-do list could soon be the hero of search and rescue missions.

Most robots that can recognise speech only respond to pre-determined instructions. For example, some powered wheelchairs respond to spoken directions, but only when certain words are spoken clearly. In the real world, that's not how humans communicate. Our speech is peppered with "disfluencies" – the "umms", "ahs" and stutters of everyday language. If we want to successfully speak to robots in real-life situations – such as search and rescue missions, where noise and stress might get in the way of clarity – robots need to understand these complications.

How Change of Seasons Affects Animals and Humans

Tomorrow (Sept. 22) at 11:09 p.m., Eastern Daylight Time, the center of the sun will cross Earth's equator, marking the autumnal equinox, and the start of fall in the Northern Hemisphere.

For a brief period, days and nights around the world each last close to 12 hours (day and night are not exactly equal, as the term “equinox” is meant to imply). Then, as the Earth continues its path around the sun, days become shorter and nights lengthen, with the change becoming more pronounced in the higher latitudes, but remaining nonexistent at the equator.
