Meet the world’s first cultured meatball.
NASA is developing a first-if-its-kind modem that incorporates light-based technology to help enable dramatically faster communications between spacecraft and ground stations.
The device, which is scheduled to be tested on board the International Space Station in 2020, is part of a broader NASA project called the Laser Communications Relay Demonstration (LCRD). This laser system, which the space agency says could dramatically overhaul today’s radio frequency (RF) communications, will enable data transmissions at rates 10 to 100 times faster than what’s currently possible.
It’s not the first time NASA has experimented with laser communications in place of radio signals. In 2013, the agency achieved record-breaking download and upload speeds to and from lunar orbit – at 622 megabits per second (Mbps) and 20 Mbps respectively – with its Lunar Atmosphere and Dust Environment Explorer (LADEE).
The year is 2021. You’re driving down the highway on your daily commute. You approach a car that’s stubbornly driving at the max speed limit. You decide to pass this overly law-abiding driver, except when you do, you discover there’s no one in the front seat.
As we learned in the first part of our Future of Transportation series, self-driving cars will become publicly available in only a few short years. But due to their component parts, they will likely be far too expensive for the average consumer. Does this mark self-driving cars as an innovation that’s dead in the water? Who’s going to buy these things?
Most articles about autonomous vehicles (AVs) fail to mention that the initial target market for these vehicles won’t be the average consumer—it will be big business. Specifically, taxi and car sharing services. Why? Let’s look at the opportunity self-driving cars represent to one of the biggest taxi/rideshare services on the planet: Uber.
UT RESEARCHERS DEVELOP ®EVOLUTIONARY CIRCUITS
Researchers of the MESA+ Institute for Nanotechnology and the CTIT Institute for ICT Research at the University of Twente in The Netherlands have demonstrated working electronic circuits that have been produced in a radically new way, using methods that resemble Darwinian evolution. The size of these circuits is comparable to the size of their conventional counterparts, but they are much closer to natural networks like the human brain. The findings promise a new generation of powerful, energy-efficient electronics, and have been published in the leading British journal Nature Nanotechnology.
One of the greatest successes of the 20th century has been the development of digital computers. During the last decades these computers have become more and more powerful by integrating ever smaller components on silicon chips. However, it is becoming increasingly hard and extremely expensive to continue this miniaturisation. Current transistors consist of only a handful of atoms. It is a major challenge to produce chips in which the millions of transistors have the same characteristics, and thus to make the chips operate properly. Another drawback is that their energy consumption is reaching unacceptable levels. It is obvious that one has to look for alternative directions, and it is interesting to see what we can learn from nature. Natural evolution has led to powerful ‘computers’ like the human brain, which can solve complex problems in an energy-efficient way. Nature exploits complex networks that can execute many tasks in parallel.

NGS — news flash; gene editing corrects genetically linked liver disease.
For the first time, researchers have treated an animal model of a genetic disorder using a viral vector to deliver genome-editing components in which the disease- causing mutation has been corrected. Delivery of the vector to newborn mice improved their survival while treatment of adult animals, unexpectedly, made them worse, according to a new study by investigators from the Perelman School of Medicine at the University of Pennsylvania The team published their findings in Nature Biotechnology.
“Correcting a disease-causing mutation following birth in this animal model brings us one step closer to realizing the potential of personalized medicine,” said senior author James Wilson, MD, PhD, a professor of Medicine and director of the Orphan Disease Center at Penn. “Nevertheless, my 35-year career in gene therapy has taught me how difficult translating mouse studies to successful human treatments can be. From this study, we are now adjusting the gene-editing system in the next phases of our investigation to address the unforeseen complications seen in adult animals.” Wilson is also director of the Penn Gene Therapy Program.
Genome pioneers “Where Are They Now?”
Fifteen years after publication of the human genome’s first draft sequence, what has become of the hundreds of researchers who worked on the project?
Aging, inflammation, cancer, and cellular senescence are all intimately interconnected. Deciphering the nature of each thread is a tremendous task, but must be done if preventative and geriatric medicine ever hope to advance. A one dimensional analysis simply will not suffice. Without a strong understanding of the genetic, epigenetic, intercellular, and intracellular factors at work only an incomplete picture can be formed. However, even with an incomplete picture useful therapeutics can and are being developed. One face is cancer, a number of diseases characterized by uncontrolled cell division. The other is slue of degenerative disorders stemming from deterioration in regenerative capacity.
Geroprotectors are a diverse and growing family of compounds that assist in preventing and reversing the unwanted side-effects of aging. Senolytics, a subset of this broad group, accomplish this feat by encouraging the removal of decrepit cells. A few examples include dasatinib, quercetin, and ABT263. Although more research must be done, there are a precious handful of studies accessible to anyone with the inclination to scroll to the works cited section of this article. Those within the life extension community and a few enlightened souls outside of it already know this, but it bears repeating: in the developed world all major diseases are the direct result of the aging process. Accepting this rather simple premise, and you really ought to, should stoke your enthusiasm for the first generation of anti-aging elixirs. Before diving into the details of this promising new pharmaceuticals we must ask what is cellular senescence? What causes it? What purpose does it serve?
Depending on the context in which they are operating a single gene can have positive or negative effects on an organism’s phenotype. Often the gene is exerting both desirable and undesirable influences at the same time. This is called antagonistic pleiotropy. For example, high levels of testosterone can confer several reproductive advantages in youth, but in elderly men can increase their likelihood of developing prostate cancer. Cellular senescence is a protective measure; it is a response to damage that could potentially turn a healthy cell into a malignant one. Understandably, this becomes considerably more complex when one is examining multiple genes and multiple pathways. Identifying all of the players involved is difficult enough. Conboy’s famous parabiosis experiment shows that alterations in the microenviornment, in this case identified and unidentified factors in the blood of young mice, can have be very beneficial to their elders. Conversely, there is a solid body of evidence that shows senescent cells can have a bad influence their neighbors. How can something similar be achieved in humans without having to surgically attach a senior citizen to a college freshman?
