Gene Involved in Neuronal Structure and Function May Protect Against Alzheimer’s Disease
Posted by Kelvin Dafiaghor in categories: biotech/medical, neuroscience
The overexpression of a gene tied to cell division and the structure and function of neurons may prevent and protect against cognitive decline in both mice and humans with Alzheimer’s disease (AD), according to a new study by scientists at the University of Colorado Anschutz Medical Campus.
The gene, Kinesin-5 or KIF11, does this despite the presence of amyloid beta (Abeta), the main component of plaques in the brains of those with AD. Scientists have traditionally targeted the plaques when looking for treatments for the fatal disease. In this case, they went around them.
The study was published online last week in the journal iScience.

Huge unveiling of schizophrenia brain cells show new treatment targets
Posted by Kelvin Dafiaghor in category: neuroscience
If you thought it was easy to analyze brain cells, think again.
When you take a brain tissue sample, all that your analysis would normally show you is an average for all the cell types present. And since there are a whole lot of cell types in our brain— neurons and others—you’ll get a sort of cell smoothie, which makes it difficult if not impossible to tell the cells apart, let alone study them.
It is like wanting to know how many green M&M’s there are in a bowl, but instead just getting told how many colors there are. You are not really getting the answer you wanted.

Elon Musk completes $44bn Twitter takeover — and immediately sacks top executives
Posted by Omuterema Akhahenda in categories: biotech/medical, Elon Musk, security
I guess it’s time for Twitter execs to go home, and for me to start using Twitter again. They killed my chamber of commerce account, then when I opened a personal account, they kept asking for my phone number every time I logged in. If I give you my number once and you send me an sms, I’m not giving it to you again, as that’s not safe.
It ends months of bad blood between the two parties regarding the takeover, with Elon Musk complaining about fake accounts on the platform and claims by a whistleblower that Twitter misled regulators about security risks.

Scientists Successfully Reverse Premature Aging
Posted by Quinn Sena in categories: biotech/medical, genetics, life extension
Werner Syndrome and Hutchinson Gilford Progeria Syndrome are two examples of the rare genetic disorders known as progeroid syndromes that cause signs of premature aging in children and young adults. Patients with progeroid syndromes have pathologies and symptoms that are often linked to aging, including osteoporosis, cataracts, heart disease, and type II diabetes.
This aging is characterized by the gradual loss of nuclear architecture and an underlying tissue-specific genetic program, but the causes are unclear. Scientists have discovered a potential new target for treating these syndromes by preventing nuclear architecture loss.
