The story of the dark side of antioxidant research isn’t well known outside of medical circles. It’s an unseemly story, profoundly unsettling; it doesn’t fit the “antioxidants are good for you” mantra that sells billions of dollars per year of blueberry- and pomegranate-fortified granola bars.
Not all vitamins are good for all people, all the time. In fact, some can kill you. And guess what? We know where the bodies are buried.
A Harvard medical pioneer calls it “astounding” — an “incredible achievement” and a “quantum leap forward” in the battle against cancer, autism, Parkinson’s and Alzheimer’s.
What’s going on? Scientists at Ohio State University say they’ve figured out a way to grow the genetic equivalent of a nearly complete embryonic human brain.
Maybe we can convince the Chinese to start funding our space program.
On Monday, Chinese scientist Youyou Tu was jointly awarded the Nobel Prize in Physiology or Medicine for her discovery of a new malaria therapy. It was remarkable research in its own right, but equally significant is the fact that Tu is the first scientist to ever be awarded a Nobel Prize for work done at a Chinese institution — despite the fact that the country trains more scientists and engineers than any other nation on Earth.
In fact, China now spends more money on research and development than Europe, and by 2020, it’s predicted to outspend the US, as Nature editor Ed Gerstner wrote last month in Research Information. But despite that investment, there’s a big reason for why Chinese science has lagged behind other parts of the world — it has a long history of pumping out dodgy research.

“The result could be a major step towards animal replacement and improved safety screening for drugs, as well as towards transplantable kidneys”
Scientists in Australia succeed in growing ‘organoids’ comparable to early stage of a baby’s kidneys that have collecting ducts and filtering units called nephons.
An article written by Dr Michael Fossel talking about telomerase therapy for Alzheimer’s and the work Bioviva and Telocyte are doing to beat this horrific condition.
Reversing Alzheimer’s by Lengthening Telomeres.
There are telomere lengthening compounds available right now for use in research labs. They are not currently available for human use. A group of scientists wants to test these compounds on aging humans now to see if the telomere lengthening effects will induce meaningful age reversal effects.
Telomeres in our cells shorten as we grow older and create cellular havoc that predisposes us to multiple age-related pathologies. These experimental enzymes promote telomere lengthening and in the process offer an intriguing opportunity to circumvent biological aging processes.
Surgeons at Brisbane hospital managed to reattached the head of 16-month-old Jaxon Taylor.

1) A heart of foam could replace your own. Existing artificial hearts have multiple moving parts, which increases the chance of failure, but this new device is just a single piece of material. Researchers inspired by soft robots have built a pumping artificial heart that could one day replace the real deal.
The team of Bioengineers at Cornell University build their robots out of a solid, plastic foam, which naturally has an interconnected network of tubes to let air flow – just as our muscles are permeated by blood vessels. A solid coating of plastic seals everything inside like a skin.

A DNA-powered PC may not be on the horizon, but DNA can still compute even if it can’t build a computer.
Warning that rapid advances in genetics make “designer babies” an increasing possibility, a United Nations panel today called for a moratorium on “editing” the human genome, pending wider public debate lest changes in DNA be transmitted to future generations or foster eugenics.
While acknowledging the therapeutic value of genetic interventions, the panel stressed that the process raises serious concerns, especially if the editing of the human genome should be applied to the germline, thereby introducing hereditary modifications.
“Gene therapy could be a watershed in the history of medicine and genome editing is unquestionably one of the most promising undertakings of science for the sake of all humankind,” the UN Educational, Scientific and Cultural Organization (UNESCO) said in a news release on a report by its International Bioethics Committee (IBC).
Memory loss is a truly devastating part of dementia, but this invention aims to fix that by bypassing the damage, and repairing long term memory.
Alzheimer’s and dementia are complex diseases, and there’s currently no effective treatment. Given the unpleasant nature of the disease, there’s an urgent need for results. Instead of taking the usual biological route, one team has constructed a prosthetic made up of a small electrode array — which can help re-encode short term memory into long term.
Built using decades of research, the device operates using a new algorithm based on accumulated neural data. New sensory information is normally translated into a quick memory and transported as an electrical signal through the hippocampus, potentially for long term storage. If this region is damaged then the process is disturbed, and new experiences fail to be encoded. Alzheimer’s patients can often remember childhood events, but struggle with recent experiences; specifically because of this hippocampal damage.
