Through a new approach dubbed AMBAR, the biotechnology company Grifols has attempted to reduce the amount of harmful, Alzheimer’s disease-causing amyloid beta in the brain by collecting it with a blood protein called albumin and draining it out of the bloodstream. This approach differs from the previous antibody and catabody approaches and offers new hope for sufferers of this neurodegenerative disease.
What is Alzheimer’s disease?
Alzheimer’s disease, named after its discoverer, is a slow and progressive disease that causes the degradation of the brains of its sufferers. This leads to memory loss, a decrease in problem-solving abilities, changes in personality, and other symptoms. It is associated with the accumulation of tau and amyloid beta in the brain.

At the Undoing Aging 2019 conference, we had the opportunity to interview Yuri Deigin, the CEO of Youthereum Genetics. His company is developing therapies that focus on OSKM, the Yamanaka factors known for turning cells back into a pluripotent state. By partially reprogramming cells using a single component of OSKM, Oct4, the company hopes to remove epigenetic aging from cells while still allowing them to retain their normal functions.
Do you think epigenetic alterations are a cause or a consequence of aging, and why?
Well, this question has so many different parts that need to be addressed. Of course, there are alterations that are consequences. Some of the epigenetics are consequences of aging, like epigenetic drift, with things that aren’t methylated in cells, as they divide throughout the lifetime, that methylation seems to get diluted away with subsequent divisions, but other parts of the genome, many of the epigenetic changes that happen that we can track throughout the aging of an organism are definitely not consequences of aging; they’re actually, from what I understand, causes of aging or causes in the change of metabolism and change of homeostasis, change how the organism behaves, essentially, that are driven by some high program in animal development, that basically silences some genes and activates other genes.

When artificial intelligence systems start getting creative, they can create great things – and scary ones. Take, for instance, an AI program that let web users compose music along with a virtual Johann Sebastian Bach by entering notes into a program that generates Bach-like harmonies to match them.
Run by Google, the app drew great praise for being groundbreaking and fun to play with. It also attracted criticism, and raised concerns about AI’s dangers.
My study of how emerging technologies affect people’s lives has taught me that the problems go beyond the admittedly large concern about whether algorithms can really create music or art in general. Some complaints seemed small, but really weren’t, like observations that Google’s AI was breaking basic rules of music composition.

Biotech is the solution to tackle the environmental impact of meat and the fertilizer shortage.
The world has focused first on energy in its effort to stop greenhouse gas emissions, but former Energy Secretary Steven Chu puts agriculture at the top of his list of climate challenges—particularly animal agriculture.
The Nobel Prize winning physicist surveyed the world’s carbon-polluting industries in a lecture at the University of Chicago, and he started with meat and dairy.
“If cattle and dairy cows were a country, they would have more greenhouse gas emissions than the entire EU 28,” said Chu, who recently assumed the presidency of the American Association for the Advancement of Science.
Two new autonomous aircraft concepts that promise to redefine the Air Force’s unmanned fleet are moving forward.
The latest, Skyborg, is an autonomous drone prototyping program underway at the Air Force Research Laboratory. Researchers hope to get the aircraft—expected to be cheaper than other platforms and easily replaceable—combat-ready by the end of 2023.
Air Force Acquisition Executive Will Roper revealed the program, which launched in October, at a conference in Washington last month. Skyborg must be able to autonomously take off and land, fly in bad weather, and avoid other aircraft, terrain, and obstacles, the Air Force said.

Galor says the study results, published on Monday, April 1, in Nature Ecology & Evolution, lend credence to what he and a colleague had surmised in a highly influential 2002 paper — that during the pre-industrial era, the natural selection of those who were genetically predisposed toward having fewer children was instrumental in spurring industrialization and sustained economic growth.
In a study of 200 years of pre-industrial Quebecois genealogical history, researchers at Brown found that fertility-related changes in natural selection during the pre-industrial era paved the way for economic and technological progress.

(Reuters) — Alphabet Inc’s Google said on Thursday it was dissolving a council it had formed a week earlier to consider ethical issues around artificial intelligence and other emerging technologies.
The council had run into controversy over two of its members, according to online news portal Vox, which first reported the dissolution of the council.
The council, launched on March 26, was meant to provide recommendations for Google and other companies and researchers working in areas such as facial recognition software, a form of automation that has prompted concerns about racial bias and other limitations.
