I don't work with biotech companies any more, but am still interested in new drug discovery.

Immune therapy is the hottest area in cancer research today. The drugs are derived from an improving understanding of how cancer cells evade detection and destruction by our immune system. Our immune systems are powerful, so much so that they can kill us if they are too active or attack things that they should not attack. We have various mechanisms to turn off the immune response. Cancer cells can mimic those mechanisms. Immune therapy involves suppressing those mechanisms or engineering immune cells that attack particular forms of cancer even when they are using those mechanisms. A few immune treatments have been approved by the FDA in the past two years. They work really well in some patients and not at all in others. As scientists try to understand what makes one patient respond to a treatment so he lives, and another not respond and die, they have been discovering a relationship with the gut biome.

The gut biome is all the microbes that live in your intestinal organs. We support huge numbers of microbes, and are starting to learn that, far from being dirty parasite to be eliminated, they are essential to our bodies' function. This will be one of the most exciting areas of research in coming decades, in part because it is easy to test hypotheses by transplanting microbes from one patient to another, or initially from one rat to another. The linked article illustrates one recent finding.

https://arstechnica.com/science/2017/11/gut-bacteria-may-make-or-break-your-chances-of-cancer-treatment-working/

I'm interested in seeing how the drug companies approach gut biome research. They need to be able to develop a patented drug. Simply learning how to cure patients won't bring profits, if anyone can do it. For example, there is a microbe called C. Difficile which is a major killer of hospitalized patients. It grows rampant in patients whose gut biome (aka gut flora) has been decimated by antibiotics, leaving C. Difficile with little competition. The conventional treatment for C. Diff is more antibiotics designed to kill C. Diff. These can suppress an outbreak, but leave the gut biome decimated and the patient at risk of re-infection, which often happens since C. Diff is very hard to eradicate from surfaces. Another way to treat C. Diff is to take fecal matter from a healthy person and introduce it into the gut of the patient, prompting his gut biome to rebuild. Since there is no way to patent this treatment or make it into a pharmaceutical, fecal transplants haven't gotten the attention, research, and marketing necessary to make the treatment widely available. If it isn't a drug, there isn't money in it.

Not quite to the "cool science" point yet, but we lifted our shiny new 70,000 lbs Inner Reflector Plug (beryllium reflector/liquid hydrogen moderators/heavy water cooling) into a test vessel this morning (for vacuum leak testing). There is only about .375" of clearance all the way down.

Authored by a co-worker, we didn't 'date' but I often took her out to dinner because she was fascinating to talk to... and she was so smart the rest of the guys were afraid to date her.

Was reading this article tonight: Nasa forecast: Which cities will flood as ice melts? - BBC News

It struck me: Why would different cities be affected by differently melting ice masses? It had to be because "sea level" is not constant.

Digging further, I found this: Sea Level not the same everywhere; up to 300 foot variation. - John Englander - Sea Level Rise Expert

Sea level varies by up to 300' globally! That is amazing.

I was in Thailand last week during the full moon and saw the extreme low tide. It was awesome to explore the ocean floor hundreds of meters out from the normal tide line. Lots of marine life that you don't normally get to see.

I thought this was pretty interesting. Not so much science as engineering.

So much science and know how goes into the making, yet the contents of the beverage can are not typically what an intelligent knowledgeable person would consume.

I hope the epoxy coating on the inside doesn't one day turn out to be poisonous, otherwise we are all done for.

Life Goes Deeper
https://aeon.co/essays/deep-beneath-the-earths-surface-life-is-weird-and-wonderful

Quote:
The amount of water in the subsurface is considerable. Globally, the freshwater reservoir in the subsurface is estimated to be up to 100 times as great as all the available fresh water in the rivers, lakes and swamps combined.

This water, ranging in ages from seven years to 2 billion years, is being intensely studied by researchers because it defines the location and scope of deep life.

We know now that the deep terrestrial subsurface is home to one quintillion simple (prokaryotic) cells. That is two to 20 times as many cells as live in all the open ocean.

By some estimates, the deep biosphere could contain up to one third of Earth’s entire biomass....................
Things that I've read in the past if I recall correctly is that ground water is only 4-percent of all fresh water, and 90 percent of Earth's bio-mass is in the soil including the seabed. I'm not sure how accurate my memory is, nor how accurate this article above is. Thing is, we are still learning and discovering, and that is pretty cool.

The Remarkable "Curvature Blindness" Illusion - Neuroskeptic

This is cool. Another optical illusion. Even looking at the image close, it looks like sharp lines at first.

NASA has developed a fission reactor the size of a desk wastebasket that produces about 1 kW or about 1.3 HP. A larger model - but not that much larger - produces about 10 kW or 13 HP. For decades . . .

By "car" do you mean RC models?

Quote:
The Kilopower reactor is designed to operate at two sizes, a one kilowatt (1,000 watt) model and a 10 kilowatt model.

“Your toaster uses about a kilowatt,” Pat McClure, Kilopower project lead at Los Alamos, says with a laugh.“In your average household, you use about 5 KW on average a day, at any given time. Realize, though, that this is a lot of energy for NASA. At NASA they’re used to tens to hundreds of watts. So to have a kilowatt or 10 kilowatts is a lot of electricity.”
I'm thinking they could use solar panels and get the same energy, no clouds on Mars.

However, don't they have storms that can tear up solar panels and wind generators - or is that just in the movies?

“Mars is a very difficult environment for power systems, with less sunlight than Earth or the moon, very cold nighttime temperatures, very interesting dust storms that can last weeks and months that engulf the entire planet,” said Steve Jurczyk, associate administrator of NASA‘s Space Technology Mission Directorate.

“So Kilopower’s compact size and robustness allows us to deliver multiple units on a single lander to the surface that provides tens of kilowatts of power,” Jurczyk added.
Okay, now I get it.

I should have read the second article first.

We (and by "we" I mean ORNL a long time ago) designed, built and tested a nuclear reactor to power an airplane (Aircraft Reactor Experiment). Crazy stuff. I can still see the towers used to hoist a reactor up in the air for shielding tests...

I was wandering around the Yucatan jungle one time and there were all kinds of heavily overgrown ancient Mayan ruins. The guide said every little pump, mound or 'mountain' down there was a ruin yet to be uncovered...
