When you think about the future and the technologies that are right around the corner, what comes to mind? Are you excited by the prospect of one day owning a refrigerator that senses when you are out of milk and eggs and contacts the store for you? Perhaps you long for the day when your home is fully automated with security, lighting, temperature and entertainment controlled by a single central computer? Recent news out of Germany highlights a technology that will prove the sky is no longer the limit.

Researchers at the Technische Universität München (TUM), under the guidance of Professor Florian Holzapfel, are developing methods for even untrained laypersons to strap into the cockpit, soar into the clouds and return safely again to the surface of the Earth. The method, involving a white skull cap and several wires, relies upon electroencephalography (EEG) readings from specific brain regions used by traditional pilots in captaining an aircraft. The EU funded project, "Brainflight," is a long-term study intended to make flying even more accessible to the average person.

"With brain control, flying, in itself, could become easier," explained Tim Fricke, one of the project leads at TUM, in a recent statement. "This would reduce the work load of pilots and thereby increase safety. In addition, pilots would have more freedom of movement to manage other manual tasks in the cockpit." This last point is true because, with mind controlled thought, the pilot would not be restricted by having to maintain contact with flight control devices or pedals.

Doctors will try to save the lives of 10 patients with knife or gunshot wounds by placing them in suspended animation, buying time to fix their injuries

Neither dead or alive, knife-wound or gunshot victims will be cooled down and placed in suspended animation later this month, as a groundbreaking emergency technique is tested out for the first time.

Surgeons are now on call at the UPMC Presbyterian Hospital in Pittsburgh, Pennsylvania, to perform the operation, which will buy doctors time to fix injuries that would otherwise be lethal.

"We are suspending life, but we don't like to call it suspended animation because it sounds like science fiction," says Samuel Tisherman, a surgeon at the hospital, who is leading the trial. "So we call it emergency preservation and resuscitation."

The technique involves replacing all of a patient's blood with a cold saline solution, which rapidly cools the body and stops almost all cellular activity. "If a patient comes to us two hours after dying you can't bring them back to life. But if they're dying and you suspend them, you have a chance to bring them back after their structural problems have been fixed," says surgeon Peter Rhee at the University of Arizona in Tucson, who helped develop the technique.

The benefits of cooling, or induced hypothermia, have been known for decades. At normal body temperature - around 37 °C - cells need a regular oxygen supply to produce energy. When the heart stops beating, blood no longer carries oxygen to cells. Without oxygen the brain can only survive for about 5 minutes before the damage is irreversible.

Like a scene right out of The Jetsons, a fleet of robotic blocks could assemble themselves into pieces of furniture that can move around the house.

A group of scientists in Switzerland is developing small robotic modules, called "roombots," which fit together like LEGO bricks to form structures that can self-assemble and morph into different shapes.


The idea of roving furniture may be somewhat disconcerting, but the researchers envision them being used to provide assistance to elderly or disabled people.

"The idea of different units that self-assemble and change morphology has been around for quite a while, but nobody came up with a good idea for how to use them," said Massimo Vespignani, an engineer at the École Polytechnique Fédérale de Lausanne, in Switzerland, andco-author of a study to be published in the July issue of the journal Robotics and Autonomous Systems.

The MPEC 2014-K35 issued on May 23, 2014 announced the discovery of a new PHA asteroid officially designated 2014 KP4. This asteroid (~ magnitude 16) was discovered by C. Jacques, E. Pimentel & J. Barros through a 0.20-m f/2.2 Schmidt-Cassegrain + CCD telescope of SONEAR Observatory (MPC code Y00), on images obtained on May 20.2, 2014.

According to the preliminay orbit, 2014 KP4 is an Apollo type asteroid. This class of asteroids are defined by having semi-major axes greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). It is also flagged as a "Potentially Hazardous Asteroid". PHA are asteroids larger than approximately 100m that might have threatening close approaches to the Earth (they can come closer to Earth than 0.05 AU).

2014 KP4 had a close approach with Earth on May 11, 2014 at rougly 26.2 LD (Lunar Distances = ~384,000 kilometers) or 0.0673 AU (1 AU = ~150 million kilometers).

We performed some follow-up measurements of this object on 2014, May 20.6, remotely from the Q62 iTelescope network (Siding Spring) through a 0.50-m f/6.8 astrograph + CCD + focal reducer. Below you can see an animation showing the fast movement (the object was moving at 6.5 "/min) of 2014 KP4 on the the sky on May 20, 2014. Each frame is a single 15-second exposure.

Russia launches 'safe search' Sputnik to rival Yandex, Google

Russian state-owned telecoms company Rostelecom has launched a trial version of its Sputnik search engine offering approved links and information helpful to everyday life, such as buying the cheapest medicine or applying for a passport.

The debut of the new search engine was announced Thursday at the 18th International Economic Forum in St. Petersburg dubbed the "Russian Davos".

The engine is referred to as "safe search", because no unchecked links should appear in its results.

"We've indexed over 10 billion documents on the Russian internet, picking the most reliable, and full and official sources of information," the company said in a statement.

"We consider the absence of unreliable information crucial for users rather than the recall ratio. Such an approach is at the core of the Sputnik concept", said Aleksey Basov, Vice President of Rostelecom and Chairman of Sputnik.

The new web-search engine aims to develop and incorporate services that might be helpful to people in their everyday life and social activities. It will be handy in daily local tasks, saving time and money, finding a petrol station with the cheapest gasoline, a nearest vet clinic, the fastest services to renovate an apartment, or links to process an official document. Sputnik will also broadcast news from several TV stations on its page.

Comment: With filters in place for extremism, child pornography and other unsavory topics, does what a company chooses not to index, or deem "unreliable," amount to protection or censorship?

Pigs can choose sex of their offspring before fertilisation, amazing new study reveals

Scientists have been left baffled after discovering female pigs may be able to tell whether a sperm will produce a boy or girl before it reaches the egg.

The study, published in the journal BMC Genomics, shows different genes are active in female pigs' reproductive system cells depending on whether female (X) or male (Y) sperm are present.

It is thought the sow's fallopian tubes, known as the oviduct, change in response, allowing her to influence the sex of her offspring.

The research suggests the sow may favour one sex over the other and give it a better chance of reaching the egg first.

Researchers are still not sure why this ability has evolved but believe if females can recognise the sex of sperm and change in response, they might be able to create an environment that favours boys or girls.

Lead author Prof Alireza Fazeli, from the department of human metabolism at the University of Sheffield said: "What this shows is that mothers are able to differentiate between the sperm that makes boys and girls.

"That on its own is amazing. It's also of great scientific and evolutionary importance.

"If we understand how they can do that, this can revolutionise the field.

"We don't know what the human application could be or how it works but we believe female pigs can choose one gender over another.

Universe is not expanding after all, scientists say


Sci-News.com
Fri, 23 May 2014 14:58 UTC
New evidence, based on detailed measurements of the size and brightness of hundreds of galaxies, indicates that the Universe is not expanding after all, says a team of astrophysicists led by Eric Lerner from Lawrenceville Plasma Physics.
Universe Not Expanding

In their study, the scientists tested one of the striking predictions of the Big Bang theory - that ordinary geometry does not work at great distances.

In the space around us, on Earth, in the Solar System and our Milky Way Galaxy, as similar objects get farther away, they look fainter and smaller. Their surface brightness, that is the brightness per unit area, remains constant.

In contrast, the Big Bang theory tells us that in an expanding Universe objects actually should appear fainter but bigger. Thus in this theory, the surface brightness decreases with the distance. In addition, the light is stretched as the Universe expanded, further dimming the light.

So in an expanding Universe the most distant galaxies should have hundreds of times dimmer surface brightness than similar nearby galaxies, making them actually undetectable with present-day telescopes.

But that is not what observations show, as demonstrated by this new study published in the International Journal of Modern Physics D.

Russian scientists and their Japanese colleagues have determined that the Chelyabinsk meteor that entered Earth's atmosphere almost 60 times the speed of sound and exploded above the Russian city back in February 2013 was formed by a space collision.

A joint study of Russian researchers from the Novosibirsk University and members of Japanese academia, in their newly published study in the Scientific Reports periodical, conclude that Chelyabinsk meteor constitutes "the second largest asteroid airburst in our recorded history."

Their study is based on the analysis of the composition of fragments of the celestial body, raised last summer from the bottom of lake Chebarkul, where parts of the meteorite fell.

"Chelyabinsk meteorite is a unique sample: it is fragments of a Near-Earth Object that actually hit the Earth and its trajectory was well-recorded," the study says.

In particular, the researchers found that the meteorite contained a jade - green mineral that is rarely found in such samples.

"We found a clear evidence for an intense impact event: the existence of a high-pressure mineral jadeite in Chelyabinsk meteorite."

Comment: Those in the know understand that the Chelyabinsk meteorite is only the opening show:

Below is a screencap of the "walkback" story headline in the LA Times posted late today.

This morning, about 5:30AM, I sent a short but succinct letter to the Editor of the Los Angeles Times (reproduced below) regarding the statements made yesterday by California Governor Jerry Brown saying that the LAX and SFO airports would "have to be moved" due to effects from posited sea level rise caused by melting of portions of the Western Antarctic Ice Sheet, some 200-800 years in the future. The claim by Governor Brown, was patently ridiculous and I wrote about it here: Governor 'Moonbeam' beclowns himself over sea level rise at LAX airport.

Pentagon plans project to combat 'space junk chain reaction,' but is it really incoming space rocks they're worried about?

Later this month the US Pentagon plans to award a massive contract to one of the two most influential American contractors for a project that, if all goes according to plan, will be able to identify space debris before it becomes a threat to the Earth.

Lockheed Martin Corp. and Raytheon Co. are competing for the $6 billion contract to design and construct Space Fence, a radar system that will eventually be able to track large bodies of space matter. The plan is being put into place so that the government can not only better predict the bodies that may come into contact with Earth (such as the asteroid that exploded over Chelyabinsk, Russia, for instance) but also to better protect satellites that could be destroyed while in orbit.

"There's a lot of stuff up there, and the impact of the new space fence will be able to track more objects and smaller objects," Joan Johnson-Freese, a professor of national security affairs at the US Naval College, told the Sydney Morning Herald, adding that the technology "is a necessity, but not sufficient...We need to move on to an active plan for removal."

The National Aeronautics and Space Administration has estimated that 500,000 chunks of man-made material floats around the Earth. Any one of those could damage or completely knock out the 1,200 operational satellites owned by various nations that are responsible for providing Internet access, banking functions, cell phone connections, Global Position System mapping, and other necessities.

Comment: Space Fence is a successor project to design and deliver globally positioned S-band radars capable of interoperation with the Space Surveillance Network. Not conveyed is what can possibly be done, once alerted, to stop a 22,000 mile-per-hour space junk collision. Since debris begets debris, the field is predicted to reach critical density beginning 2015 and initiate a chain reaction (Kessler Syndrome), enough to render low earth orbits unusable and too hostile for future space use. Is the Pentagon justified to spend multi-billions on a space junk tracker? Or, could it be the uptick of incoming comets and asteroids is the real tracking priority lurking in the background not being talked about?
