DARPA Bounces Smart Radar Off Buildings To Track Individual Urban Vehicles From The Sky

Tracking from Above It's difficult to use radar in urban environments because of all the structures that get in the way. But by bouncing highly sensitive radar off of buildings' facades, DARPA hopes to lock onto individual vehicles from UAVs and track them through urban streets even when buildings block line of sight. Zemlinki

From Popular Science:

Radar is great for tracking objects in the wide-open sky or even at sea, but when you try to take it to street level you run into some obstacles -- literally. Radar requires a good line of sight, and obstructions like buildings or terrain features can render radar useless. But now, using a handful of unmanned aircraft and technology that allows them to intelligently reflect radar off buildings, DARPA is developing a system that should be able to track individual vehicles even as they dart between skyscrapers and other structures.

Mind Over Matter? How Your Body Does Your Thinking

Let your body do the thinking (Image: Stephen Simpson/Image Bank)

From New Scientist:

"I THINK therefore I am," said Descartes. Perhaps he should have added: "I act, therefore I think."

Our ability to think has long been considered central to what makes us human. Now research suggests that our bodies and their relationship with the environment govern even our most abstract thoughts. This includes thinking up random numbers or deciding whether to recount positive or negative experiences.

UV Radiation, Not Vitamin D, Might Limit Multiple Sclerosis Symptoms

From Science News:

Sunshine effects on MS might be more complicated than previously thought, mouse study suggests.

Ultraviolet radiation from sunshine seems to thwart multiple sclerosis, but perhaps not the way most researchers had assumed, a new study in mice suggests.

If validated in further research, the finding could add a twist to a hypothesis that has gained credence in recent decades. The report appears online March 22 in the Proceedings of the National Academy of Sciences.

From Live Science:

After months of grueling tests, a species of horned dung beetle takes the title for world's strongest insect.

The beetle, called Onthophagus taurus, was found to be able to pull a whopping 1,141 times its own body weight, which is the equivalent of a 150-pound (70 kilogram) person lifting six full double-decker buses. While the study researcher knows of a mite that can take on a hair more, that organism is an arachnid, not an insect.

From Reuters:

(Reuters) - Hundreds of computer geeks, most of them students putting themselves through college, crammed into three floors of an office building in an industrial section of Ukraine's capital Kiev, churning out code at a frenzied pace. They were creating some of the world's most pernicious, and profitable, computer viruses.

According to court documents, former employees and investigators, a receptionist greeted visitors at the door of the company, known as Innovative Marketing Ukraine. Communications cables lay jumbled on the floor and a small coffee maker sat on the desk of one worker.

My Comment: A good chunk of my family (on my father's side) lives in the Ukraine. One of my cousin .... a software programmer, worked for a few months in such a company. Apparently the pay was great, and the people who he worked with were fun. I only learned about this later, because if I had learned about when he was working there, I would probably have gone down to his house and beat him over the head for being stupid enough to be affiliated with such criminals.

Because of my work in managing computer networks, I have had more than my share in tackling these vicious viruses. I have lost tons of information, and worse .... megaloads of my life in cleaning up the mess that such attacks always produced.

This Reuters article is a good one in outlining the problems and obstacles that need to be overcome to stop this type of cyber crime. This is a must read for all geeks, and for the individual user who has been a victim of this type of attack.

Climate Change Disaster Killed Off The 'Terrible Lizards' And Helped Dinosaurs To Rule The Earth

Changes: Dinosaurs came to rule the world as a direct result of a
mass extinction similar to the one that killed them off

From The Daily Mail:

Dinosaurs came to rule the world as a direct result of a mass extinction similar to the one that killed them off and allowed mammals to take over the planet, research has revealed.

History was repeating itself when a climate change disaster ended the 200million year reign of the 'terrible lizards', evidence suggests.

A massive asteroid impact is believed to have altered the world's climate and wiped out the dinosaurs, giving mammals the opportunity they had been waiting for to flourish.

10 Wonders Of The Solar System

(Image: NASA / JHU-APL / Southwest Research Institute)

From New Scientist:

Moons may bow to planets in terms of size, but in character they often outshine their stolid parents. The named moons of the solar system outnumber planets by more than 20 to 1, and they display a remarkable diversity. There are fully fledged worlds such as Titan, as complex as any planet. There are possible havens for life, such as the ice-crusted water world Europa. New mysteries surround even the smallest satellites, most recently the apparent flying saucers orbiting Saturn.

This year it will be four centuries since Galileo discovered Jupiter's four large satellites, at a stroke quintupling the number of moons then known to humanity.

Join Stephen Battersby for a tour of some of te most frigid, violent and downright strange worlds we have discovered since then.

Weird 'Dark Flow' Seen Deeper Into The Universe Than Ever

From Space.com:

The puzzling migration of matter in deep space – dubbed "dark flow" – has been observed at farther distances than ever before, scientists have announced.

Distant galaxy clusters appear to be zooming through space at phenomenal speeds that surpass 1 million mph. The clusters were tracked to 2.5 billion light-years away – twice as far as earlier measurements.

This motion can't be explained by any known cosmic force, the researchers say. They suspect that whatever's tugging the matter may lie beyond our observable universe.

How Do You Force Criminals To Change Their Behavior?

From Boston.com:

How do you force criminals to change their behavior?

Over the last 35 years, the US criminal justice system has been spectacularly bad at answering this question. America is the most punitive nation in the world, with 2.4 million of its citizens behind bars and another 5.1 million on probation or parole. Yet according to the latest national statistics, two-thirds of released prisoners commit another serious offense within three years. After a generation of draconian crime policy, America’s crime rates are still among the highest in the Western world. Instead of one costly problem, we now have two: crime and mass incarceration.

UN Body To Look At Meat And Climate Link

Livestock's Long Shadow calculated meat-related emissions from field to abattoir

From The BBC:

UN specialists are to look again at the contribution of meat production to climate change, after claims that an earlier report exaggerated the link.

A 2006 report concluded meat production was responsible for 18% of greenhouse gas emissions - more than transport.

The report has been cited by people campaigning for a more vegetable-based diet, including Sir Paul McCartney.

But a new analysis, presented at a major US science meeting, says the transport comparison was flawed.

Does Geothermal Power Cause Earthquakes?

Geothermal Hot Spots: Many hot spots sit in seismically active areas. Paul Wootton

From Popular Science:

A new energy method could trigger a risky side effect.

On December 8, 2006, Markus Häring caused some 30 earthquakes -- the largest registering 3.4 on the Richter scale -- in Basel, Switzerland. Häring is not a supervillain. He's a geologist, and he had nothing but good intentions when he injected high-pressure water into rocks three miles below the surface, attempting to generate electricity through a process called enhanced geothermal. But he produced earthquakes instead, and when seismic analysis confirmed that the quakes were centered near the drilling site, city officials charged him with $9 million worth of damage to buildings.
