Solar Powered E-Skin for Prosthetic Limbs
Posted by Gerard Bain in categories: biotech/medical, cyborgs, health, sustainability, wearables
Recently University of Glasgow developed a Graphene based E-Skin for prosthetic limbs. The research started with making a prosthetic arm that could sense even the minutest of pressure for gripping soft objects. It eventually yielded a prosthetic limb that was also self powering.
This was because of the development of Graphene based supercapacitors.

New ‘interspecies communication’ strategy between gut bacteria and mammalian hosts uncovered
Posted by Xavier Rosseel in categories: biotech/medical, health, neuroscience
A study published today in Cell describes a form of “interspecies communication” in which bacteria secrete a specific molecule — nitric oxide — that allows them to communicate with and control their hosts’ DNA, and suggests that the conversation between the two may broadly influence human health.
The researchers out of Case Western Reserve University School of Medicine, University Hospitals Cleveland Medical Center, and Harvard Medical School tracked nitric oxide secreted by gut bacteria inside tiny worms (C. elegans, a common mammalian laboratory model). Nitric oxide secreted by gut bacteria attached to thousands of host proteins, completely changing a worm’s ability to regulate its own gene expression.
The study is the first to show gut bacteria can tap into nitric oxide networks ubiquitous in mammals, including humans. Nitric oxide attaches to human proteins in a carefully regulated manner — a process known as S-nitrosylation — and disruptions are broadly implicated in diseases such as Alzheimer’s, Parkinson’s, asthma, diabetes, heart disease, and cancer.

The human body might survive a mission to Mars better than our minds

Though astronaut Scott Kelly’s year in space showed us spaceflight can change the human body, new research suggests the bigger concern should be our minds.

Woman with heart and double-lung transplant praises new technology
Posted by Paul Battista in category: biotech/medical
Three years ago Kate Phillips, who has suffered congenital heart disease her whole life, received a heart and lung transplant which saved her life.
But her successful operation isn’t a reality for many patients on vital organ waiting lists.
Out of 381 hearts only 81 were successfully transplanted in Australia last year. Hearts are usually lucky to withstand a transport time of about four hours, with only one in four reaching operating tables.

Ending Age-Related Diseases Conference: February Update
Posted by Steve Hill in categories: biotech/medical, business, life extension
July 2019 will see the launch of our second Ending Age-Related Diseases conference at the Frederick P. Rose Auditorium, Cooper Union in New York City. The event was so popular last year that we decided to expand it to two full days of science and biotech business this year.
We will be bringing you the latest aging research, investment, and business knowledge from some of the top experts in the industry. We will be packing two days full of talks from and discussion panels with the people who are developing the technologies that could change the way we regard and treat aging forever.
With just over a month left to grab a lower-cost early bird ticket for the event, we thought that it would be a good opportunity to take a look at what we have in store. We have already announced lots of inspiring speakers from the research and business sectors of the industry, and here are just a few of them.

Hachimoji DNA doubles the genetic code
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, evolution, genetics
Researchers in the US have built an “alien” DNA system from eight building block letters, so expanding the genetic code from four and doubling its information density. The new system meets all of the requirements for Darwinian evolution and can also be transcribed to RNA. It will be important for future synthetic biology applications and expands the scope of molecular structures that might be capable of supporting life, both here on Earth and more widely in the universe.
One of the main characteristics of life is that it can store and pass on genetic information. In modern-day organisms, this is done by DNA using just four building blocks: guanine, cytosine, adenine and thymine (G, A, C and T). Pairs of DNA strands form a double helix with A bonding to T and C bonding to G.
Four more building blocks .

A New Treatment Can Relieve Food Allergies, But Few Doctors Offer It
Posted by James Christian Smith in categories: biotech/medical, food, health
Because there’s not yet an FDA-approved version of this treatment, most medical providers don’t yet offer it. So most patients can get it only by enrolling in research studies, of which there have been dozens in recent years.
Patients Find Relief For Food Allergies In Oral Immunotherapy Treatment : Shots — Health News Many parents of kids with life-threatening food allergies live with fear, EpiPen in hand. Some are trying oral immunotherapy, a treatment that can help patients build tolerance to foods like peanuts.

Making New Drugs With a Dose of Artificial Intelligence
Posted by Derick Lee in categories: biotech/medical, robotics/AI
Universities and big pharmaceutical companies are unlikely to match those resources. But thanks to cloud computing services offered by Google and other tech giants, the price of computing power continues to drop. Dr. AlQuraishi urged the life-sciences community to shift more attention toward the kind of A.I. work practiced by DeepMind.
Researchers at DeepMind, owned by Google’s parent company, and other companies are applying their powerful A.I. systems to drug discovery research.

Forget the Blood of Teens. This Pill Promises to Extend Life for a Nickel a Pop
Posted by James Christian Smith in categories: biotech/medical, life extension
NIR BARZILAI HAS a plan. It’s a really big plan that might one day change medicine and health care as we know it. Its promise: extending our years of healthy, disease-free living by decades.
The more researchers learn about metformin, the more it seems like a medieval wonder drug that could extend lifespans in the 21st century.
