Anti-vaxx propaganda has gone viral on Facebook. Pinterest has a cure

Since my previous post about Youtube and anti-vaccination was such a hit, here’s now Pinterest handles it. They broke their own search engine to keep these things from getting passed around. They also blocked the ability to pin links or images from any number of pseudoscience websites such as Mercola, Natural News, GreedMedInfo, and HealthNutNews.

They also did this to their hash-tag library to keep people from finding workarounds.

O n Wednesday morning, Adam Schiff, the powerful chair of the House intelligence committee, joined journalists around the world in a nascent Twitter meme: he searched “vaccine” on Facebook and posted a screenshot of the results.

Schiff’s search results were indeed alarming: autofill suggestions for phrases such as “vaccination re-education discussion forum”, a group called “Parents Against Vaccination”, and the page for the National Vaccine Information Center, an official-sounding organization that promotes anti-vaccine propaganda. And while search results on Facebook are personalized to each user, a recent Guardian report found similarly biased results for a brand new account.

If the congressman had tried to search “vaccines” on the rival social media site Pinterest, however, he would have had little more to screenshot than a blank white screen. Recognizing that search results for a number terms related to vaccines were broken, Pinterest responded by “breaking” its own search tool.

Doubling Our DNA Building Blocks Could Lead to New Life Forms

That’s why Ellington sees a more immediate use for the technology in the up-and-coming field of DNA data storage. Large tech firms and startups alike are evaluating whether nucleotides can beat out silicon when it comes to long-term, archival information storage. DNA is notoriously data-dense, and the arrival of hachimoji just doubled its information-carrying capacity.

But first, chemists hope to improve DNA data storage and churn out new medical compounds.

Solar Powered E-Skin for Prosthetic Limbs

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.

Graphene is now being explored for wearable electronics and health pathes because of its flexibility and ability to pick the smallest of signals.

New ‘interspecies communication’ strategy between gut bacteria and mammalian hosts uncovered

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.

Woman with heart and double-lung transplant praises new technology

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

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.
