Why the Higher Education System Is Unsustainable (i.e. Doomed)

Posted on by

“That which is unaffordable is unsustainable and will go away. The current system of higher education is profoundly unaffordable: it exists on an immoral foundation of student debt–$560 billion of which is Federal. Enormous expansions of student debt are required to keep the current system of higher education afloat. This chart shows the insane trajectory of Federal student debt.  But unaffordability is only one reason why the present system of higher education is unsustainable.  Despite the good intentions and hard work of individuals, these systems are broken.  Due to their size and structure, large systems such as national defense, healthcare and education limit the impact of individual initiative.”

Dozens of British universities join the online education revolution

Posted on by

“Dozens of British universities began offering free online courses on Wednesday through a collective portal, joining a global trend started in the United States that opens higher education to the masses.  Pre-registration opened on Tuesday and in one day 20,000 people from 158 different countries signed up — even though the portal site will not be completed for several months.  Until then it will run in beta phase, without all the finishing touches, so organisers can see how it works.  The scheme brings British universities in line with many of their rivals in the United States, where so-called massive open online courses (MOOCs) are hugely popular.”

Yahoo Japan develops 3D search engine-printer

Posted on by

“Yahoo Japan Corp. has developed a voice-activated Internet search that links to a 3D printer, letting users look online for blueprints to deliver solid objects in a few minutes, the company said.  The search engine scours the Internet for information that it can use to print palm-sized renderings of items as diverse as hippopotamuses or fighter jets. Heralded as a technology that is potentially as game-changing as the steam engine was in its day, 3D printers have become a more commonplace reality over the last few years.
The devices use slices of information about a three-dimensional object and gradually deposits fine layers of material — such as plastic, carbon or metal — to build a copy.”

Researchers create battery that recycles sewage into energy

Posted on by

“They hope their technique could be used in wastewater treatment facilities and to break down organic pollutants in the ‘dead zones’ of oceans and lakes where fertilizer runoff has depleted oxygen, suffocating marine life.  However, for now the team from Stanford University have started small, with a prototype about the size of a D-cell battery, consisting of two electrodes — one positive and one negative — plunged into a bottle of wastewater, filled with bacteria.  As the bacteria consume the organic material, the microbes cluster around the negative electrode, throwing off electrons, which are captured in turn by the positive electrode.”

The Next Step in Killing Cancer

Posted on by

“The protein that Olson is describing is called chlorotoxin. It’s a major component of the venom injected from the sting of a scorpion’s tail.  Once it’s infused into the bloodstream, the venom naturally travels to the brain and attaches itself to chloride channels that lay on the surface of cells.  And as it turns out, chlorotoxin actually prefers the chloride channels on tumor cells above all other tissues.  Upon realizing this fascinating discovery, the Blaze Bioscience team re-engineered chlorotoxin. They tagged it with molecules that literally act like a flashlight for doctors.  It’s a fluorescent dye that illuminates the outline of the tumor in its entirety, making it easier for brain surgeons to operate without error.”

Intel turns wine into electricity to power mobile devices

Posted on by

“Demonstrating what is probably the perfect solution for energy conscious winos out there, an Intel Labs researcher talked through the project on stage alongside Bell, showing off a low-power processor and an accelerometer that were powered by a glass of wine. The researcher – we didn’t catch his full name – boasted that the computing solutions being worked on in Intel Labs are so low in power that in the future we’ll be able to ‘power them by the heat of our skin, or the ambilight in the room’, or ‘something a little more entertaining’, he added, pointing at the wine glass hooked up to the accelerometer.”

Posted on by

“In this modern world, airway is the most convent medium of travel in terms of time and safety and its global presence. The number of people travelling by air is constantly rising every day and so is the number of aircraft and airports. There are more than 40,000 thousands airports around the globe used for civilian and cargo transport. This list is gives the top 10 busiest airports in the world in terms of the total annual passenger transition registered. Naturally this kind of list always changes, what we listed below is as per the data of the year 2012.”

NASA: Voyager 1 becomes first spacecraft to leave our solar system

Posted on by

“NASA’s Voyager 1 probe has now left the solar system and is wandering the galaxy, US scientists said Thursday. The spacecraft was launched in 1977 on a mission to explore the outer planets of our solar system and to possibly journey into the unknown depths of outer space.  US space agency scientists now agree that Voyager is officially outside the protective bubble known as the heliosphere that extends at least eight billion miles  beyond all the planets in our solar system, and has entered a cold, dark region known as interstellar space.  Voyager’s instruments will have to shut down permanently in 2025, Science reported. NASA spends $5 million per year to operate the twin spacecraft.”

Cygnus cargo spacecraft is on its way to the International Space Station

Posted on by

“Orbital’s Cygnus cargo spacecraft is now on its way to becoming the second commercial cargo vehicle to service the International Space Station. The Antares rocket carrying the Cygnus cargo spacecraft lifted off on schedule at 10:58 am EDT (1458 GMT) Wednesday and placed the Cygnus spacecraft into earth orbit.  The spacecraft is carrying 700 kilograms of supplies, more than any previous commercial cargo mission to the station, Orbital’s Frank Culbertson said at a post-launch press conference (a subtle dig at SpaceX’s three Dragon flights to the station.)”
