Limb regeneration activation genes found in mammals and regenration of heart tissue and paws activitated in mice

Posted by in category: biotech/medical

If you trace our evolutionary tree way back to its roots — long before the shedding of gills or the development of opposable thumbs — you will likely find a common ancestor with the amazing ability to regenerate lost body parts.

Researchers have built a running list of the genes that enable regenerating animals to grow back a severed tail or repair damaged tissues. Surprisingly, they have found that genes important for regeneration in these creatures also have counterparts in humans. The key difference might not lie in the genes themselves but in the sequences that regulate how those genes are activated during injury.

A Duke study appearing April 6 in the journal Nature has discovered the presence of these regulatory sequences in zebrafish, a favored model of regeneration research. Called “tissue regeneration enhancer elements” or TREEs, these sequences can turn on genes in injury sites and even be engineered to change the ability of animals to regenerate.

Researchers find that ribose, the ‘R’ in RNA, could form naturally in space

Posted by in category: alien life

Though the quest to find water on distant planets is the most talked-about way that researchers are looking for extraterrestrial life, one of our best bets at understanding life’s complexities lies with comets, not planets.

In fact, the icy space balls are already known to form amino acids and nucleobases, two key substances needed for life to take root. And now, researchers may have found another necessary ingredient: ribose, the ‘R’ in RNA.

Before we dive into the new discovery, it’s important to understand what life, as we know it, needs to get started, and how we think it may have happened here on Earth. Life on Earth requires three macromolecules: RNA, DNA and proteins. The current understanding is that RNA, or ribonucleic acid, came before DNA on Earth.

128 Things that will disappear in the driverless car era

Posted by in categories: finance, robotics/AI, transportation

I started writing this column while I was in Manila, Philippines for a talk with UnionBank, one of the most innovative banks I’ve ever come across.

Driving across Manila is often a painful experience with far too many cars locking up all possible arterials, and nowhere near enough money to redesign and build the needed infrastructure. But this is not unique to Manila.

As I’ve traveled around the world, I’ve run into equally bad traffic in Istanbul, Rotterdam, Los Angeles, Seoul, Mexico City, San Francisco, Rome, London, Beijing, and Mumbai. In fact there are literally thousands of cities where bad traffic is a way of life.

Venture Capitalist 3D Prints a Rocket Faster Than the Speed of Sound for Under $2

Posted by in categories: 3D printing, computing, space travel

Steve Jurvetson is a man of many facets – and he can 3D print a rocket that achieves Mach 1.8 (that’s 1,363 mph) in 2.6 seconds and reach an altitude of nearly 9,500 feet.

The Mach number is named after the Austrian physicist and philosopher, Ernst Mach. The terms “subsonic” and “supersonic” basically refer to speeds below and above the local speed of sound, so you should have some idea how fast these tiny rockets are traveling.

Smartphones should fully embrace the dual-camera bandwagon

Posted by in categories: electronics, mobile phones

One of the biggest rumors surrounding the iPhone 7 is that Apple is adding a second camera module (at least on the Plus model), and it makes a lot more sense than you might realize.

After all, other manufacturers have already caught on. LG’s G5 comes with a ultra-wide angle lens, Huawei’s new P9 sports a dedicated black-and-white camera, and HTC beat everyone to the punch with the One M8’s depth-sensing camera a couple of years ago.

Our biggest ever edition of TNW Conference is fast approaching! Join 10,000 tech leaders this May in Amsterdam.

Houston Methodist and NASA launching unique nanomedicine experiment

Posted by in categories: biotech/medical, particle physics

Along with equipment and supplies for the astronauts, the rocket was supposed to deliver several scientific experiments, including one Grattoni and his team spent five years perfecting: a study of how drug-like particles disperse through 100 tiny channels etched in a dime-sized microchip. […] it hit him: the rocket — and his work — was gone. Led by Grattoni, the center has secured coveted approval to conduct several experiments in coming years aboard the $100 billion space station, where scientists can exploit the lack of gravity about 200 miles above the Earth’s surface to perform studies they wouldn’t otherwise be allowed to do on Earth.

Vaccine Delivery Systems that May Protect Against Bioterror Threats & Outbreaks

Posted by in categories: biotech/medical, nanotechnology, terrorism

Most traditional vaccines have safety and efficacy issues, whereas particulate vaccine delivery systems—which utilize nano- or micro-particulate carriers to protect and deliver antigens—are efficient, stable, include molecules to bolster immune responses, and minimize adverse reactions due to the use of biocompatible biomaterials.

A new review, titled “Particulate delivery systems for vaccination against bioterrorism agents and emerging infectious pathogens,” summarizes the current status of research efforts to develop particulate vaccine delivery systems against bioterrorism agents and emerging infectious pathogens.
