Brain cell powerhouses appear good treatment target for stroke, TBI recovery

Posted by in categories: biotech/medical, neuroscience

Cell powerhouses are typically long and lean, but with brain injury such as stroke or trauma, they can quickly become bloated and dysfunctional, say scientists who documented the phenomena in real time for the first time in a living brain.

The scientists also found that without giving these mitochondria anything but time, they often resume their usual healthy shape once blood and oxygen were restored to mild or moderately damaged tissue, said Dr. Sergei Kirov, neuroscientist in the Department of Neurosurgery at the Medical College of Georgia at Augusta University.

“We believe this is good evidence that mitochondria can recover their normal form following brief periods of ischemia from stroke or trauma and that drugs that enhance their recovery may improve overall recovery from these sorts of injuries,” Kirov said.

Self-Driving Cars Will Fail

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

The article does bring up many of the same points that many have raised with self driving cars; and folks still don’t seem to understand that we have thousands if not millions of laws in the US alone that must be reviewed and possibly changed to address this technology on the roads. When you look at every state, each county, and each town or city’s laws around driving on their roads; it could be a long and painful period for companies and consumers before the legal side of things catch up.

Self-driving car technology is not yet ready for prime time. Driver assist is.

The Legal challenges and potential liability are immense.

Researchers reveal how cancer cells cope with genetic chaos

Posted by in categories: biotech/medical, genetics

Another difference between normal and abnormal cells — cancer cells can continue to grow despite damage to cell structures and changes in the number of chromosomes.

Scientists have uncovered how tumours are able to grow despite significant damage to the structure and number of their chromosomes — the storage units of DNA — according to two new studies published in Cancer Cell and Cancer Discovery today.

“We hope that understanding these mechanisms will allow us to limit drug resistance and improve the efficacy of cancer therapies.” - Professor Charles Swanton

Neural connection keeps instincts in check

Posted by in categories: biological, neuroscience

Scientists identify the physical connection through which the prefrontal cortex inhibits instinctive behavior

From fighting the urge to hit someone to resisting the temptation to run off stage instead of giving that public speech, we are often confronted with situations where we have to curb our instincts. Scientists at the European Molecular Biology Laboratory (EMBL) have traced exactly which neuronal projections prevent social animals like us from acting out such impulses. The study, published in Nature Neuroscience, could have implications for schizophrenia and mood disorders like depression.

Brian Greene: Time Travel is Possible

Posted by in categories: particle physics, time travel

Is the time we experience in our day-to-day lives real? Here, theoretical physicist Brian Green explores the potential particles of time and why we could, in theory, travel forward in time but not back.

Sayōnara, Humans: Japanese Company Replaces Its Workers with AI

Posted by in category: robotics/AI

A Japanese company is laying off 34 workers and replacing them with artificial intelligence based on IBM’s Watson Explorer. While advancing automation may be helpful in alleviating Japan’s aging and declining population, what does this mean for other workers across the globe?

Scientists Have Found a Drug That Regenerates Teeth, and It Could Reduce the Need for Fillings

Posted by in categories: biotech/medical, materials

Researchers have identified a drug that can regenerate teeth from the inside out, possibly reducing the need for artificial fillings.

The drug was previously used in Alzheimer’s clinical trials, and it now appears to improve the tooth’s natural ability to heal itself. It works by activating stem cells inside the tooth’s pulp centre, prompting the damaged area to regenerate the hard dentin material that makes up the majority of a tooth.

“The simplicity of our approach makes it ideal as a clinical dental product for the natural treatment of large cavities, by providing both pulp protection and restoring dentine,” said lead author Paul Sharpe from King’s College London.

Neodriven is a rearview mirror replacement that can make your car semi-autonomous

Posted by in categories: Elon Musk, robotics/AI, transportation

In late 2015, iPhone and PlayStation 3 hacker George Hotz teased a project that sounded like a dream: his new company would produce a $1,000 consumer product that could grant your car semi-autonomous capabilities. Eleven months and one terse letter from the National Highway Traffic Safety Administration later, Hotz killed the project.

About a month after that, Hotz resurrected it as a two open-source efforts, splitting the hardware and software of the self-driving tech he had created with the rest of his company, Hotz always talked like he wanted to start a DIY car revolution to take on the car industry (and Elon Musk especially). Open sourcing the plans only increased the chances of it happening.

Calorie Restriction as a Means to Improve Surgical Outcomes

Posted by in categories: biotech/medical, food, health, life extension

More data for caloric restriction and health benefits.

The long-term response to calorie restriction has long been of interest to the aging research community, and particularly in the past few decades as the tools of biotechnology allowed for a more detailed analysis of the metabolic changes that accompany a reduced calorie intake. A restricted diet extends healthy life spans in near all species tested to date, though to a much greater extent in short-lived species than in long-lived species such as our own. Considerable effort is presently devoted to the development of drugs that can replicate some fraction of calorie restriction — more effort than is merited in my opinion, given that the optimal result for extension of human life span achieved via calorie restriction mimetics will be both hard to achieve safely and very limited in comparison to the gains possible through rejuvenation therapies after the SENS model. Repairing damage within the existing system should be expected to outdo attempts to change the system in order to slow the accumulation of damage, in both efficiency and size of result.

Not everyone is interested in the long term, however. The short term health benefits of calorie restriction appear quickly and are surprisingly similar in mice and humans, given that calorie restriction in mice results in significantly extended life and calorie restriction in humans does not. The beneficial adjustments to metabolism and organ function are for the most part larger and more reliable than similar gains presently achievable through forms of medicine. That is more a case of medical science having a long way to go yet than calorie restriction being wondrous, however. Still, the short term benefits are coming to the attention to wider audience within the research and medical community.

Don’t Thank Big Government for Medical Breakthroughs

Posted by in categories: biotech/medical, economics, government, life extension

Grassroots funding of fundamental science and private enterprize will lead the way in rejuvenation biotechnology not the traditional funding sources from Government which are shrinking every year.

It is important to understand that innovation and progress is unlikely to come from the Government and the traditional grant system which is shrinking every year. Rejuvenation biotechnology will likely be funded with a mix of fundraising for fundamental breakthrough technologies followed by private enterprize taking discoveries to market. This is why supporting science is critcial as relying on the Government to innovate and drive progress is unlikely to yield results anytime soon.

“Today, researchers compete for government grants at increasingly shorter intervals and with diminishing chances of success: Less than 1 in 5 grant applications succeeds. This inhibits risk taking.
