Dr Haroldo Silva from SENS talks about ALT cancer in this short film.

As normal cells divide, the ends of their chromosomes (telomeres) progressively shorten until eventually the cells reach senescence or undergo apoptosis. Cancers, which disproportionally kill more individuals in the 65 years or above age group, often overcome this built-in replication limit by expressing the enzyme telomerase.

Time people rethought outdated ideas about biology and accepted that development and aging are not one way processess and they are amenable to intervention.

Scientists have announced they can now reverse the menopause in what is thought to be a major scientific breakthrough.

Trials claim to have ‘rejuvenated’ women’s ovaries using a blood treatment normally used to help wounds heal faster and have reversed menstrual cessation in multiple women, including 40-year-old woman who underwent the menopause five years ago.

The first prototype of DeLorean appeared in October 1976, and production officially began in 1981 in Dunmurry, a suburb of south west Belfast, Northern Ireland (with the first DMC-12 rolling off the production line on January 21). The car features gull-wing doors and an innovative fiberglass chassis and underbody structure, along with a brushed stainless steel body.

DMC became famous for its appearance and was modified as a time machine in the Back to the Future film trilogy. A little more than 8,500 DMC-12s left DeLorean’s factory in Northern Ireland between 1981 and 1983, until its founder John DeLorean’s was arrested by the FBI on charges of drug trafficking.

Actually, it is quite impressing that Texas-based DeLorean Motor Company could soon initiate again its production thanks to a new law which exempts small volume car manufacturers from the safety requirements applied to the newly cars. On January 27, 2016, in Humble, Texas location, the car maker announced that production will resume and “new” DMC-12’s will be rolling off the assembly line in early 2017.

Technology can be confusing when it begins moving at such an accelerated rate, perfectly exemplified by the 3D industry, and encompassing all that goes with it, from 3D scanning to 3D printing and then peripheral industries that are often connected too such as augmented and virtual realities. We’ve barely digested all the stunning innovations making impacts in so many different sectors, from 3D printed medical models that allow for more complex surgeries, to 3D printed parts for a suspension system that make racing bikes go faster, all the way to incredible toys for your kids using augmented reality systems.

Yet, while work is definitely just beginning in the 3D realm, scientists have already begun exploring a range of uses for 4D technology that should prove offer impacts in just as many applications, from the medical field to electronics and far beyond. It might seem like a lot all at once, but the two technologies definitely work together, with the 4D emphasis adding a more intuitive, smart angle to fabrication.

As we’ve seen in other studies using the application of heat, it would appear that 3D printed objects can be treated or manipulated to cause shapes to morph according to their environment, as well as remembering their previous state and going back to it in the appropriate conditions. Now, teams from both MIT and the Singapore University of Technology and Design (SUTD) are employing light in their endeavors to create smart structures. They’ve had good success too, if the amount of torturing they’ve put these materials through is any indication. According to the engineers, they’ve twisted, bent, and stretched everything from small coils to flowers fabricated out of numerous materials, and even a replica they made of the Eiffel tower. As is the case with structures being pushed into the 4D realm, all of the above materials reverted.

Brain maps seem to come out in rapid succession these days. They take various forms: a map for word concepts, a map of individual cells’ activity, a map based on the organ’s physical contours.

What they share in common is the aspiration to take the lumpy mass of the brain and categorize it, somehow, into useable areas — not unlike the textbook brain images with their colored denotations of “occipital lobe” and “frontal cortex.”

But these maps often come along with a problem: They may not sync up with the other maps. Now a group of scientists have managed to sync up two of the most commonly used types of brain maps — for gene expression and brain structure — and they’re releasing their methods to any and all in the scientific community.

If you want them to, that is.

Researchers at Bar Ilan University and the Interdisciplinary Center in Herzliya, both in Israel, have developed new technology that allows tiny bots to release drugs into the body controlled by human thought alone. The test involved a man using his thoughts to activate nano robots inside a cockroach.

The bots have been built using a DNA origami structure with hollow shell-like components, and they come with a “gate” that can be opened and shut with the help of iron oxide nanoparticles that act as a “lock” – which can be prized open using electromagnetic energy.

The Israeli team believe the bots could help in controlled release of drugs over time. Led by Dr Ido Bachelet of Bar Ilan University, scientists demonstrated how to control this process with human brainwaves. Using a computer algorithm, they trained the system to detect when a person’s brain was under strain from doing mental arithmetic. The team then placed a fluorescent drug in the bots and injected them into various cockroaches that were placed inside an electromagnetic coil.

Many lower organisms retain the miraculous ability to regenerate form and function of almost any tissue after injury. Humans share many of our genes with these organisms, but our capacity for regeneration is limited. Scientists at the MDI Biological Laboratory in Bar Harbor, Maine, are studying the genetics of these organisms to find out how regenerative mechanisms might be activated in humans.

The ability of animals to regenerate body parts has fascinated scientists since the time of Aristotle. But until the advent of sophisticated tools for genetic and computational analysis, scientists had no way of studying the genetic machinery that enables regeneration. Using such tools, scientists at the MDI Biological Laboratory have identified genetic regulators governing regeneration that are common across species.

In a paper published in the journal PLOS ONE, MDI Biological Laboratory scientistsBenjamin L. King, Ph.D., and Voot P. Yin, Ph.D., identified these common genetic regulators in three regenerative species: the zebrafish, a common aquarium fish originally from India; the axolotl, a salamander native to the lakes of Mexico; and the bichir, a ray-finned fish from Africa.

#CRISPR can be used to alter the genes of not only one organism, but an entire species, through a method of inheritance known as a gene drive. But what happens if something goes awry?
