Diamond-based imaging system uses magnetic resonance of electrons to detect charged atoms.
Scientists are beginning to realize that many cellular behaviors, such as metastasizing cancer cells moving through the body or wound healing, aren’t random events, but the result of coordinated actions by cells.
Such collective cell movement requires communication, and a new study shows that cells are most effective at communication when they aren’t tightly packed together. This was a surprise, says Andrew Mugler, a Purdue University assistant professor of physics and astronomy who studies cell behavior.
“Our hypothesis was proven wrong,” Mugler says. “Our hypothesis was that cells that are closer to each other should experience a sensory improvement. Instead, we found that long-range communication was better, even though it meant that cells had to be receiving weaker communication signals.”
Speaking at the Aspen Abu Dhabi Ideas Forum, Dr Brad Perkins, chief medical officer, Human Longevity, said: “Right now the most daunting and expensive human health problem that the world is facing is age related chronic disease. Our hypothesis at Human Longevity is that genomics and the technologies that support its application in medicine and drug discovery are going to be the next accelerant in extending a high performance human lifespan.
Dr. Brad Perkins and other anti-aging researchers at commercial companies made the more conservative for anti-aging researchers that within about 40 years human longevity (maximum lifespan) will reach 140 years. Current life expectancy is about 80 years but with some countries and states at about 90 years for women. The confirmed longest lived person reached 122 years of age.
A newly published patent from Made in Space describes several systems that could be used for 3D printing in space. These include, “a system and method for assembling a spacecraft such as a satellite in space.”
Michael Snyder, Chief Engineer and co-founder at Made in Space, is named as inventor on the patent.
Every day in a San Diego lab, raw material derived from donated tissue unsuitable for organ transplantation goes into a machine, and three-dimensional human liver tissue is printed out.
Pioneered by a company called Organovo, this 3D bioprinting technology may one day achieve the Holy Grail of its industry: the manufacturing of whole human organs to replace damaged ones. But for now, it’s already making an impact on human health, as pharmaceutical and biotech companies are using its manufactured human liver tissue to test the toxicity of new drugs and therapies.
Organovo is developing multiple tissue types for therapeutic use, with strong early results in animal models. In three to five years, there’s a good chance that it will have an Investigational New Drug Application in at least one tissue. The company’s strategic plan is coming to fruition just as its chief scientific officer, Sharon Presnell, envisioned when she joined the startup in 2011.
SpaceX hopes to take paying passengers into deep space next year. Is this a real business or an ego trip?
An awfully big adventure
Elon Musk announced on Monday (27 February) that his space company SpaceX has been contracted by two private citizens to circumnavigate the moon and return to Earth late in 2018. The mission will not land on the Moon but the two privileged individuals will get close. And they have already paid a substantial deposit.
How rejuvenation can make motherhood (and more generally, parenthood) better.
I’m not really a children person. I know some people really are into having children and think that it’s the most wonderful thing in life, but I’m just not one of them. This is perfectly fine. Whether having children is a wonderful thing or not is a matter of opinion, and it is not true or false in an absolute sense. What’s more, it’s not necessarily set in stone forever: I don’t like the idea now, but I can’t be 100% sure I never will; conversely, people who love the idea now might not like it any more in the future.
However, having children is a bit more serious than a simple matter of personal taste. A child is not a toy or a dress that you buy and just put away if it turns out you don’t like it as much as you thought you would: It’s a living human being whom was brought into the world because of someone else’s intentions and/or actions, and it’ll need love and care for quite a while. For this very reason, I think you should have children only if you’re pretty damn sure you really want to and are prepared to do all it takes to raise them. It’s not an easy job, and if it turns out you hate it, you’ll probably end up doing it wrong, messing up the child’s life and your own in the process. This is true of women and men, though women definitely picked the shortest straw. I’ll tell you why I think so in a moment.
Even if you think you are ‘pretty damn sure’ that you want children, you could still be wrong for a number of reasons that aren’t necessarily your fault. If you do decide to have children and then realise you don’t like it, you have good 18+ years ahead of you of bearing with the consequences of your wrong decision. The decision to not have children is, in a sense, safer, because it can easily be undone: Later on, you can change your mind and have children. If you already did make a child, changing your mind about it will not undo the child. However, not having children is only marginally safer, because as things stand you can postpone parenthood only so long before it becomes impossible or impractical (again, especially if you are a woman). The bottom line is that the current state of affairs imposes you a risky choice—having or not having children—that cannot easily (or at all) be undone.
Airbus has proposed a new modular transportation idea mixing air and ground travel that will make you feel that the future cannot get here fast enough.
Unveiled today at the Geneva International Motor show, the system, dubbed “Pop. Up,” would start with a capsule that sits in the frame of an autonomous car. When traffic gets heavy, you just call a drone using your smartphone and lift the capsule up into the air and over the heads of those poor suckers stuck in traffic sucking on exhaust fumes.
The company says a new artificial intelligence platform will help manage the Pop. Up system, letting passengers optimize the mix of modalities for their trip.
