Researchers are inching ever closer to bringing the latest stem-cell technologies from bench to bedside — and are, in the process, learning more about some diseases that long have remained medical black boxes.

This week, scientists at the Harvard Stem Cell Institute (HSCI) reported the first success in generating new populations of insulin-producing cells using skin cells of Type 1 diabetes patients. The achievement involved the newer embryo-free technique for generating stem cells, and marked the first step toward building a treatment that could one day replace a patient’s faulty insulin-making cells with healthy, functioning ones.

The experiment, published in the Proceedings of the National Academy of Sciences, also provided the first good model — in a petri dish — of how Type 1 diabetes develops, giving scientists a peek at what goes wrong in patients affected by the disease. Such knowledge could lead to not only new stem-cell-based treatments, but also novel drug therapies that might improve the symptoms of the disease.

Douglas Melton, co-director of HSCI, and his team took skin cells from two Type 1 diabetes patients, exposed the cells to a cocktail of three genes that converted them back to an embryonic state — which are referred to as pluripotent stem cells — then instructed the newly reborn cells to grow into beta cells, the cells in the pancreas that secrete insulin. In Type 1 diabetes, these beta cells no longer work to break down the glucose that floods the body after each meal, leading to blood-sugar spikes that can damage the kidneys and heart.

To test whether their lab-made cells could function like normal beta cells, Melton’s group exposed them to glucose in a dish. When sugar levels were high, the cells produced more of a protein that beta cells release when they break down sugar; when glucose levels were low, the protein levels were low as well.

"These cells represent the newest model of diabetes for humans," says Melton. "We have a lot of good models of Type 1 diabetes in the mouse, but everything that we have learned from them has failed in the clinic. Now we have a chance at figuring out how humans get the disease."…

Jumping the SPAC

Note: I was not under influence of Zacapa or edibles writing this one … so it’s wonky.  Oh well, my blog.

A perfect storm may be brewing: tech, software as a service (SaaS), and climate change. My podcast co-host, Kara Swisher, believes the first trillionaire will be an entrepreneur who addresses climate change. It’s not unthinkable, as Elon Musk is already 15% of the way there — to a trillion in wealth, not solving climate change. I’m more skeptical and believe the only entities that can begin to reverse climate change are the EU and the governmen...

The Inelastic Market Hypothesis: Exposing The Fallacy Of Fun-Durr-Mentals

Via RealInvestmentAdvice.com,

If you take a quick look at returns for the S&P 500 over the last few years, it is easy to be impressed with how lucrative stocks can be. Total returns above 31% in 2019, 18% in 2020, and 21% year-to-date (as of 8/31) can make a difference. Unfortunately, the levitation at the end of this summer hardly stands out in this context. Instead, it is just more of the same.

Delta is tempting us to trade lives for freedoms — a choice it had looked like we wouldn’t have to make

Last year COVID-19 seemed simple. It was horrific, but the arguments about what to do were fairly straightforward.

On one side were people rightly horrified by its rapid spread who wanted us to stay at home and stay away from school and work and socialising in order to save lives.

On the other side were people concerned about the costs of those measures — to jobs, to educati...

Gold and Silver Volume Waves Review

Courtesy of Read the Ticker

The sign says it all. The professionals want the public to focus on the words, to scare out the weak hands, but the color of the sign underlines the value in a money printing world, its gold stupid.

Point and figure (PnF) charts draw price waves with the sum of volume per wave. PnF charts high light true accumulation underneath price action. This is why Richard Wyckoff favored PnF charts.    

In the charts below we see price moving sideways to down, yet volume on up waves are greater than volume on down waves. At the moment there is no heavy selling on down waves. Or in other words price is being moved down at a low volume expense to allow accumulation at a lower price.

This action represents professionals building their...

Crude Oil Cleared For Blast Off On This Dual Breakout?

Courtesy of Chris Kimble

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

Managing Investments As A Charity Or Nonprofit

Maintaining financial viability is a constant challenge for charities and nonprofit organizations.

Q4 2020 hedge fund letters, conferences and more

The past year has underscored that challenge. The pandemic has not just affected investment returns – it’s also had serious implications for charitable activities and the ability to fundraise. For some organizations, it’s even raised doubts about whether they can continue to operate.

Finding ways to generate long-term, sustainable returns for ...

The Suez Canal: A Critical Waterway Comes to a Halt

On March 23, 2021, a massive ship named Ever Given became lodged in the Suez Canal, completely blocking traffic in both directions. According to the Suez Canal Authority, the 1,312 foot long (400 m) container ship ran aground during a sandstorm that caused low visibility, impacting the ship’s navigation. The vessel is owned by Taiwanese shipping firm, Evergreen Marine.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

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...
