Scientists Move Closer to Understanding Why We Age

Scientists Move Closer to Understanding Why We Age

By Eben Harrell / London, courtesy of TIME 

Time waits for no man, the old truism goes, but in recent years scientists have shown that it does seem to move more slowly for some. Molecular biologists have observed that people’s cells often age at different rates, leading them to make a distinction between "chronological" and "biological age."

But the reason for the difference remains only vaguely understood. Environmental factors such as smoking, stress and regular exercise all seem to influence the rate at which our cells age. Now, for the first time, researchers have found a genetic link to cellular aging — a finding that suggests new treatments for a variety of age-related diseases and cancers. 

The field of "biological aging" has in recent years focused on the long molecules of DNA contained in human cells called chromosomes. All chromosomes have protective caps at either end called telomeres. Each time a cell replicates itself (as it does before it dies), the telomeres shorten, like plastic tips fraying on the end of shoelace. Shortened telomeres have been linked to a host of age-related illnesses such as heart disease and certain cancers. (Scientists have yet to study whether telomeres influence a person’s appearance). Last year’s Nobel prize in medicine was awarded to three American scientists for their work in the field, and many scientists now believe telomeres are the closest we may come to identifying a biological clock — and our best bet for one day learning how to stop or turn back that clock. 

To better understand the aging discrepancy, a team of researchers in Britain and The Netherlands scanned more than 500,000 genetic variations across the human genome. Using a population of nearly 12,000, they then attempted to pinpoint a genetic link to telomere length. (See how to prevent illness at any age.) 

In a significant breakthrough, the team successfully identified that a particular gene sequence was associated with differences in telomere length between individuals. What’s more, the sequence was clustered near a gene called TERC, which is already known to play a role in the production of an enzyme called telomerase. Telomerase repairs telomeres when they shorten. "That was very exciting for us," says Professor Nilesh Samani, a cardiologist at the University of Leicester who co-led the research, published last week in Nature Genetics. "It gave us great…

Coronavirus stimulus checks: McConnell ready to delay Aug recess

By Aman Jain. Originally published at ValueWalk.

We are now just days away from the August 7 deadline for the next coronavirus package. Though negotiators are working hard to come up with a deal, there are still differences between the two sides. In case there is no decision on the coronavirus stimulus checks deal by August 7, Senate Majority Leader Mitch McConnell has assured that they will delay the scheduled recess. Presently, the last day in session is scheduled for August 7, after which the Senate will go on a month-long break until September 8.

Silver Headed Back To $50, Top Of The Cup & Handle Pattern?

Could Silver be creating a multi-decade bullish “Cup & Handle” pattern? Possible!

Did a retest of a handle breakout take place in March at (1), where Silver created one of the largest bullish reversals in decades? Possible!

Could Silver be creating a 40-year bullish pattern? Anything is possible! I humbly have to say share this; I’ve been in the business for 40-years and I haven’t seen anything like this.

Silver looks to have double topped back in 2011 at $50, which was the 1980 highs. After double topping, Silver ...

Twitter Says "Human Error" And "Spear-Phishing Attack" Responsible For Massive Bitcoin Hack

Courtesy of ZeroHedge

Twitter suffered from a major hack about two weeks ago and has now said that its staff was tricked by "spear-phishing", which is a targeted attack to trick people into simply handing out their passwords. 

Twitter staff were targeted through their phones, according to a new report from the BBC. The attacks then allowed hackers the ability to Tweet from celebrity Twitter accounts. Twitter has said it was "taking a hard look" at how it could improve its permissions and processes.

"The attack on July 15, 2020, targeted a small number of employees through a phone spear phishing attack. This attack relied on ...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
