An eye test could predict whether someone could have Alzheimer’s disease years in advance, according to a recent study.

Researchers from Cedars-Sinai and company NeuroVision Imaging found the disease affects the retina, which is the back of the eye, in a similar way to how it impacts the brain. Through this discovery, researchers conducted a noninvasive eye scan in an effort to detect key signs of Alzheimer’s before patients began experiencing symptoms of the disease.

The study, which was published Tuesday in JCI Insight, said a high definition eye scan was able to see the plaque in the retina, which correlated with the amount in the brain. The plaque is a buildup of toxic proteins called amyloid-beta deposits, which are key signs of Alzheimer’s. Build up in the brain may occur as early as two decades before people begin to experience signs of the disease.

Scientists recently used a gene-editing tool to fix a mutation in a human embryo. Around the world, researchers are chasing cures for other genetic diseases.

Now that the gene-editing genie is out of the bottle, what would you wish for first?

Babies with “perfect” eyes, over-the-top intelligence, and a touch of movie star charisma?

What if traffic flowed through our streets as smoothly and efficiently as blood flows through our veins? Transportation geek Wanis Kabbaj thinks we can find inspiration in the genius of our biology to design the transit systems of the future. In this forward-thinking talk, preview exciting concepts like modular, detachable buses, flying taxis and networks of suspended magnetic pods that could help make the dream of a dynamic, driverless world into a reality.

Autophagy means “eating of self” (“auto”= self; “phag” = eating)[1]. Although its name might sound harmful, autophagy appears to have longevity-promoting effects[2]. Here, we will explain what autophagy is, how it works, its benefits, and how it plays a role in aging.

What is Autophagy?

Autophagy is the way cells break down misbehaving or nonfunctional organelles and proteins in the cell[1,2]. This means autophagy can consume organelles such as, mitochondria, peroxisomes, and the endoplasmic reticulum[1].

The Italian version of Rejuvenaction is up and running! If you know Italian speakers who would like to know about rejuvenation biotechnologies and advocacy, please let them know!

I’m pleased to announce the launch of Rejuvenaction Italia, the Italian version of Rejuvenaction. As you might know, Italian is my native language, and while I have neglected/postponed online advocacy in Italian for over two years now, I realised that, as the topic of rejuvenation starts to reach broader audiences, there’s a necessity to make information available in several languages, for the benefit of those who don’t speak English. Regardless of one’s native language, the questions people have about rejuvenation are always the same: How do you do it? Why? Have you thought of overpopulation? And tyrants living forever? and so on. Thus, Rejuvenaction Italia (henceforth officially nicknamed RJi, and accordingly Rejuvenaction will be simply RJ) is essentially a clone of RJ, except in Italian. The blog won’t be nearly as lively as that here on RJ because, you know, there are only 24 hours in a day. I will translate some of the most substantial posts or important news from RJ to RJi, though, and there will be RJi -specific posts that won’t be worth translating into English.

If you speak Italian and/or know someone who does, it may be worth checking out RJ’s Italian clone and share the news on your social media. I would appreciate that very much. 🙂 There’s a link to RJi at the top of the sidebar.

As I translated the contents of RJ into Italian, I took advantage of the occasion to rewrite some articles that were long due for an update, and added entire new sections. You might have noticed them silently popping up here on the English site, together with a minor graphics revamp.

DUBLIN, August 21, 2017 /PRNewswire/.

The “Regenerative Medicine Market, 2014 — 2025” report has been added to Research and Markets’ offering.

The global regenerative medicine market size is expected to reach USD 5.59 billion by 2025, according to this new report. Increased prevalence of neurodegenerative, orthopedic, and other aging-related disorders in geriatric population coupled with rising global geriatric population is anticipated to drive market growth.

The immune system as a whole can be broadly separated into two main branches: the innate immune response and the adaptive immune response. The innate immune response is performed by a system that is always present across the body, while the adaptive immune response appears only in response to an infection and is always specific to a particular infectious agent. B cells are a part of the adaptive immune system.

B cells are one of the two types of lymphocytes, the other kind being T cells. Like most immune cells, B cells have a very specific function: the production of antibodies, which play a major role in immunity. However, in order for a B cell to produce antibodies it must first become activated.
