Functional thymus organ grown in mice from lab-created cells

August 26, 2014

Fibroblasts transformed into induced thymic epithelial cells (iTEC) in vitro (left, iTEC in green). iTEC transplanted onto the mouse kidney form an organised and functional mini-thymus (right, kidney cells in pink, thymus cells in dark blue) (credit: MRC)

Scientists have for the first time grown a complex, fully functional organ from scratch in a living animal by transplanting cells that were originally created in a laboratory to form a replacement thymus*, a vital organ of the immune system.

The advance could in the future aid the development of “lab-grown” replacement organs.

Michigan State University researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to see through the window.

It is called a transparent luminescent solar concentrator (TLSC) and can be used on buildings, cell phones, and any other device that has a clear surface.

Robo Brain is currently downloading and processing about 1 billion images, 120,000 YouTube videos, and 100 million how-to documents and appliance manuals, all being translated and stored in a robot-friendly format.

The reason: to serve as helpers in our homes, offices and factories, robots will need to understand how the world works and how the humans around them behave.

Robotics researchers like Ashutosh Saxena,… read more

George Mason University neuroscience researcher Todd Gillette got a preview of the forthcoming movie Autómata. It “caught me completely by surprise,” he said on his OnMason blog. “Starring Antonio Banderas, here we have a believable future (2044, 30 years from now) in which desertification is threatening society, and a single company is leading the way in intelligent robotics.”

You’ve been prevented from accessing your smart phone, computer, tablet, and TV for five days. Do you (A) totally freak out and go into withdrawal or (B) deal with it and regain some of your lost social skills, like reading emotions?

UCLA scientists found that sixth-graders who went five days without even glancing at a smartphone, television, or other digital screen chose option B. They did substantially… read more

The National Science Foundation (NSF) has announced two $10 million projects, called “Chameleon” and “CloudLab,” to create cloud-computing testbeds to help the academic research community develop and experiment with novel cloud architectures and applications.

The NSF is especially interested in real-time, safety-critical applications like those used in medical devices, power grids, and transportation systems.

Ask HitchBOT, a charismatic robot who just hitchhiked its way across Canada from Halifax, N.S. to Victoria, B.C. — a three-week journey of more than 6,000 km (3728 miles) — accepting 18 rides from total strangers and tweeting its progress to its 35,100 followers.

@HitchBOT used GPS and a 3G cellphone wireless connection feeding to a map with its position. It has… read more

How lizards regenerate their tails: researchers discover genetic ‘recipe’

Finding may impact future therapies for spinal cord injuries, birth defects, arthritis, other conditions

Arizona State University scientists have discovered the genetic “recipe” for lizard tail regeneration, which may help develop future therapies for spinal cord injuries.

The team studied the regenerating tail of the green anole lizard (Anolis carolinensis), which when caught by a predator, can lose its tail and then grow it back.

The findings were published Aug. 20 in the journal PLOS ONEread more

A low-cost water splitter that runs on an ordinary AAA battery

Could allow for true zero-emissions fuel-cell vehicles and save hydrogen producers billions of dollars in electricity costs
August 22, 2014

Stanford scientists have developed a low-cost device that uses an ordinary AAA battery to split water into oxygen and hydrogen gas. Gas bubbles are produced by electrodes made of inexpensive nickel and iron.

A cheap, emissions-free device that uses a 1.5-volt AAA battery to split water into hydrogen and oxygen by electrolysis has been developed by scientists at Stanford University.

Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive, abundant nickel and iron.

“This is the first time anyone has used non-precious metal catalysts to split water at a voltage… read more

Delivery by drone: will it work?

MIT has two computational tricks to help

MIT researchers have devised computational solutions to reduce the chances that Amazon’s planned delivery drones will crash and burn — along with your stuff.

It’s complicated. Drones have to deal with iffy factors like high winds, low fuel/power level, component failures, and even possible shooters in some locations.

So with Boeing support, the researchers developed two fixes.

  • An algorithm enables a drone to monitor aspects of

Q: What do you get when you add graphene to a rubber band?

A: A flexible sensor sensitive enough for medical use that can be made cheaply.

So say researchers from the University of Surrey and Trinity College Dublin, who have done just that.

Once treated, the rubber bands remain highly pliable, the researchers report, and graphene can be used as a sensor to measure a patient’s… read more

Remote-controlled cyborg moth ‘biobots’ to monitor emergency-response operations

North Carolina State University researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals that moths use to control those muscles. The goal: remotely-controlled moths, or “biobots,” for use in emergency response, such as search and rescue operations.

“The idea would be to attach sensors to moths … to create a flexible, aerial sensor network that can identify survivors… read more

MIT chemical engineers have devised a new treatment for bone injuries or defects: an implantable tissue scaffold (structure) coated with bone-growth factors that can be released slowly over a few weeks to induce the body to rapidly form new bone that looks and behaves just like the original tissue.

On Monday this week, KurzweilAI described a shape-memory polymer that expands with warm salt water to… read more

University at Buffalo researchers are developing a new imaging technique using nanoparticles suspended in liquid to form “nanojuice” that patients would drink to help diagnose irritable bowel syndrome, celiac disease, Crohn’s disease and other gastrointestinal illnesses.

Doctors would strike the nanoparticles, once they reach the small intestine, with a harmless laser light, providing an unparalleled, non-invasive, real-time view of the organ.

Bacteria that aid in digestion keep the intestinal lining intact, scientists at Albert Einstein College of Medicine of Yeshiva University and associates have found.

The findings, reported online in the journal Immunity, could yield new therapies for inflammatory bowel disease (IBD) and a wide range of other disorders.

The research involved the intestinal microbiome, which contains some 100 trillion bacteria. The role of these microorganisms in… read more
