The fact that they are devoting two hours to tell the first part of the story gives me a lot of confidence that they are taking the time to tell the story in a deliberate way. I have written elsewhere that this series really reminds me of Mushishi and everything I liked about that show, so I am super excited that they seem to be giving it the pacing that it needs to help the story hit.

I have read the manga and the early manga definitely gives me Kino's Journey/Mushishi vibes. Those are two of my all-time favorite anime and Frieren is probably the closest I have ever come to having that same feeling in manga form. So, I am super excited about it as well.

The type of pill that was approved is the progestin-only "mini pill" which has a much safer clinical profile than the more common-in-the-US combination pill that has both progestin and estrogen. This type of pill is already available OTC in over 100 other countries. The US is just really behind the curve on just about anything to do with reproductive rights and care.

This piece resonated with me as I also did not really envision myself working in industry when I started grad school; figuring that I would just stay in academia in one form or another. However, when I started to look outside academia (after seeing lab mates stuck in endless post-doc loops), I was surprised at the breadth of opportunities that were available.

Even though my degree was in physics, I was doing stuff relevant to several different industries. I interviewed for roles in data science, materials science, petrochemicals, food science, and pharma. Ultimately, I ended up in pharma and the very first program I worked on was an immunotherapy to target the type of cancer that caused the death of my grandfather. It wasn't some grand design on my part, just a coincidence that echoes some of what this author experienced.

The issue seems to be how the data was collected in the Phase 3 trial:

Clinical trials of most drugs and vaccines supporting FDA approval are mainly conducted in the U.S. and Europe, where clinical trial protocols are well recognized. The phase 3 TIDES trial used for Qdenga’s application was run in several less well-off, dengue-endemic regions in Latin America and Southeast Asia.

However, it should be noted that Takeda's drug, Qdenga, is already approved by the EMA in the EU and a couple other agencies. It is just the FDA that is holding things up in the US.

Yeah, even comments here haven't seemed to read the article. As somebody that used to install BOINC on all my machines back in the day, the reason I stopped is that many of the projects I ran (SETI being one) aren't active any longer. Also, like the article mentioned, I just don't have a desktop anymore and I am not about to run something like this on a laptop that doesn't have things like user-serviceable or replaceable parts.

I think that @[email protected] provided a great response for the specific case of flow in a pipe.

I just want to add that if you look beyond the restrictions of flow in a pipe, there are many other types of behavior that non-Newtonian fluids exhibit. We measure this in the lab on instruments called rheometers. Basically, we put some liquid in the instrument and then deform it and measure the resistance to that deformation. One of the most common ways to apply that deformation is to do so back and forth in an oscillating manner. Depending on the frequency at which you apply this strain, the solid/liquid-like behavior can change. If you have some background in physics or want to get a decent understanding, I found this paper that, on skimming it, seems to be pretty consistent with the way I was taught this stuff in grad school.

One graph I want to point out is Figure 13 which shows what would be a "typical" viscoelastic polymer solution. An easy way to understand this graph is that as we go from left to right, we are applying strain back and forth quicker and quicker, essentially shaking it faster. When the G' value is higher than the G" value, then the material is behaving more like a solid and conversely, when G" > G', then it is behaving more like a liquid. You can see that the material goes through different phases of behavior as the strain frequency changes. Just for you I went and dug up an old graph from my thesis to show a real-life example of this happening too.

My favorite demonstration of this is to put Oobleck (or something similar) onto a speaker and then change the frequency and see what happens.

I haven't editorialized the title, but I don't like it since the desired protein structure was thought up by the grad student and the "digitally designed" piece just seems to be some MD modelling to confirm the desired outcome before synthesis.

That being said, I thought this was interesting since freeze/thaw (F/T) stress is ubiquitous in the life sciences and something that is especially important to the emerging field of cell therapy. Typically, excipients like sucrose, trehalose, or glycerol are used to preserve biological molecules during F/T, but they are not protective in every case. Developing alternative means to protect during F/T gives people like me that develop therapeutic formulations more options to turn to in the case of difficult molecules.

This is about a recent study looking at the rheology of fondant. Essentially, fondant is created from a supersaturated solution of sucrose that is agitated (kneaded). This causes the fondant to experience a sequence of events:

  1. First, the agitation induces crystal nucleation and growth. In the early stages of crystal formation, the surrounding solution is depleted of sucrose, reducing the bulk viscosity.
  2. However, as the crystals grow in size, they are large enough to push against one another in hard sphere-like interactions. This causes a sharp increase in viscosity at this critical crystal size.
  3. As agitation continues, sucrose crystals fracture and the system reaches an equilibrium crystal size distribution, causing the viscosity to decrease from its peak. This is the final state of a smooth, pliable fondant.

There is a doi provided by the article, but as of my posting this, the doi hasn't been activated yet.

The fine is from an unrelated, earlier incident in Alabama. From what I found on jalopnik:

Earlier this year, a worker was killed by being sucked into an airplane engine in Alabama on New Year’s Eve. The employee in that scenario was warned several times that the plane’s engines would be on, however. Still, OSHA hit the small airline Piedmont with a fine of $15,625 in the workers death.

This incident with Delta that happened in Texas is under investigation.

This is a summary of a Phase 1/2 trial of a cell therapy meant to stimulate insulin production in diabetes patients. The top line is that it met its clinical endpoints and several of the patients no longer require external insulin dosing at all and their blood sugar is well managed. Vertex also has a number of follow-up therapies in the pipeline meant to improve upon this therapy.

I personally don't have much experience in cell therapy, but the potential of a treatment like this is clear. We will see what the data looks like as this goes through the clinical trial pipeline and expands the patient population in Phase 3.

That's fair. I couldn't find much info on their website, so I assumed this was another make insulin cheap using "biohacking" deal. I don't have any experience with small molecule synthesis or dry powder manufacturing, so I can't really speak to how feasible this may be. However, having seen first-hand all the ways simple manufacturing steps can go wrong, the risk of consuming a medication that hasn't been through rigorous QA/QC makes me very wary.

[-] [email protected] 21 points 1 year ago

Apologies for the long post. I don't mean this as an attack on OP, just trying to illustrate why actually doing this is a bad idea.

I have seen efforts like this in the past, especially centered around efforts to manufacture insulin cheaply. While I get that medicine cost and availability is broken at a fundamental level in the US, the solution is a political one rather than to run a wildcat bioreactor. There is simply no way to safely manufacture biologics using a 3d printed bioreactor. Let's look at the manufacturing process to get an idea of why.

Staring with the bioreactor, you would need some way to sterilize it before use (not just sanitize, there's a difference). There are plastic bioreactors that are used in industry, but they are large, single-use bags that are sterilized using gamma or x-ray radiation. Most industry bioreactors are made of stainless steel to withstand the harsh treatment required to re-sterilize them (steam or hydrogen peroxide).

Moving down the chain from the bioreactor, you need some way to remove your product from the harvested liquid. This is usually done through lysing the cells you have grown and then running this lysate through a series of chromatography columns of varying types (affinity, ionic, etc.) to systematically remove all the junk left over from your cellular media and the cells you have lysed. Even if you could (unsafely) grow your cells and drug in a 3d printed bioreactor, you don't have these kinds of things at home and can't just get them from Amazon.

However, let's say that you could get past the purification step, what's next? You find yourself with a large volume of very dilute medicine suspended in a chromatography buffer. The next step is what is called UF/DF, or ultra-filtration/dia-filtration. This step, paradoxically done DF first, uses filter membranes and large amounts of buffer and some pressure to first swap out the buffer that your medicine is in to the target formulation that you want to inject and then concentrate it down to a manageable volume. If you are working at small scale, then you can probably replace this step with just one filter and a centrifuge. Remember that while you are doing all this, everything that comes into contact with your drug needs to be sterile (even the air).

I think I have made my point, but for actual drugs there are more steps beyond this. Post-UF/DF is what is referred to as drug substance (DS) in the industry. You still need to go through a sterile fill-finish process to get drug product (DP) that is what is actually given to a patient. If you really want, I can go on another long tirade here since this is the step my job focuses on.

I have worked on these manufacturing processes and seen them fail a lot for very hard to catch problems. Without all the in-process controls and testing we do, there would have been serious risks of giving bad DP to patients. If you have read this far, then I hope I've convinced you not to give this kind of thing a try.

The real problem this is trying to solve is a political one. We should be advocating for better access to medications and reforming how costs are dealt with. It doesn't matter what your political persuasion is, I think everyone agrees healthcare in the US is broken and it's time something is done about it.

This summarizes a report from Parks Canada about the reintroduction of bison to the Banff National Park.

A Parks Canada report published this week concluded that the reintroduction was a success, and it suggested that due to their robust growth rate, this bison subpopulation—one of only five that occupy a mere 0.5 percent of their original range in North America—may no longer be considered endangered within a decade.

This paper details a new hydrogel patch coated in microneedles used to delivery medication to tissues. The design of the patch was inspired by the Blue-ringed octopus and the method by which it administers toxins.

Unrelated to this paper (which is really cool) I feel like scientific figures have really fallen prey to a trend to cram too much information into each figure, making them impossible to comprehend. This paper as an example features two figures that go all the way from A through L. If you have to use almost half the alphabet to label your figures, maybe something can go to supplemental information.

Exposure to microgravity causes changes to the human immune system:

"Here we show that the expression of many genes related to immune functions rapidly decreases when astronauts reach space, while the opposite happens when they return to Earth after six months aboard the ISS," said Dr. Odette Laneuville, an associate professor at the Department of Biology of the University of Ottawa, leading author of a new study in Frontiers in Immunology.

Back in the olden days of reddit, mods didn't need to accept their position. So, it was a troll tactic to promote people to moderator of a controversial sub and then take a screenshot. I have no knowledge of spez's moderating history, but I imagine this is the most likely scenario.

This pretty much lines up with my take as well. Educating borrowers via the first three bills on true costs, expected earnings, and repayment options is fine, but is mostly done already. I don't see how mandating a form that needs to be signed saying that you understand the debt you are taking on is going to change that.

The fourth bill is pretty blatantly ideologically motivated. If they truly think that these programs are worth less, then a better solution might be something like tying the cost of tuition for different majors to the expected earnings potential rather than eliminating aid eligibility.

The fifth bill would have a dramatic impact on graduate students. I am lucky enough that I did my PhD back when a graduate student stipend could (just barely) cover living expenses. However, graduate student pay has not kept up with cost of living, and grad students often take out the PLUS loans to help bridge the gap. Eliminating these would essentially price out a lot of grad students in HCOL areas that don't have family wealth to draw from. Alternatively (and preferentially), it could motivate schools to actually pay a living wage to grad students. However, the most likely outcome is that schools would just bring in more wealthy international students to fill the enrollment gap.
