Who Will Benefit From New Wireless Internet Bandwidth?
When WiFi was first launched in the 1990s (based on the growing set of IEEE 802.11 standards, for those who care about provenance), it had a small range at the 2.4 Gigahertz (GHz) radio frequency. In 1999, a more capable range at 5GHz range was added. And now 6GHz is just appearing on the market.
Radio waves are sort of all the same, no matter the space between their peaks. Therefore, the differences between 2.4, 5, and 6 GHz are a matter of quantity and the trade-offs they make. We shouldn’t expect a sudden new capability just because we’re in a new frequency band. On the other hand, the quantitative differenc...

Clinical Trials 101: A digression
I ' m going to take a break from explaining the right way to do clinical trials to say a bit about a really, terribly, awful bad way to do it.That would be homeopathy. The link is to a piece about a consumer organization that is suing CVS for putting homeopathic " remedies " on the shelf next to actual over the counter medications that might do something useful. (A lot of them don ' t really either but that ' s another story.)First there ' s the question of biological plausibility. Homeopathy is radically and irremediably inconsistent with everything we know about physics, chemistry and biology. If we believe everyth...

An old interview with one of this year ’ s Nobel Chemists – Carolyn Bertozzi
This was an interview for my Personal Reactions column on the old ChemWeb site from 1999 featuring Carolyn Bertozzi, who this week was announced as one of three recipients of the 2022 Nobel Prize in Chemistry.
Biography: Professor Carolyn Ruth Bertozzi, born 10th October 1966. Boston Massachusetts.
Position: Associate Professor of Chemistry, University of California at Berkeley
How did you get your current job?
The usual way. I applied for faculty positions in 1995 in response to advertisements in C&E News
What do you think clinched the deal?
Good fortune and a strong publication record from my graduate and postdoctora...

Does the Aortic root contract or relax during ventricular systole ?
Some time back I asked this question in one of my classes for the fellows and found no takers. Not even a guess? I realized later it was indeed a tough question. The heart is not the only dynamic organ as we generally believe. The entire aorta which is the extension of the left ventricle has to be dynamic according to the physics of ventricular-arterial coupling and the momentum of blood flow.
What happens to the aortic dimension with systole?
Even prior to systole, there is evidence, Aorta gets ready to receive the blood from the LV. So, the Aortic root is larger at the onset of systole. (Ref 2 It is been g...

What is science?
Sapiens, by Yuval Harari, is subtitled A brief history of humankind, and that ' s exactly what it is. It ' s mostly stuff I already knew in broad strokes, although obviously it has a lot of specific detail and illustrative examples I wasn ' t familiar with. I don ' t agree with everything he says -- for one thing, he seems not to have read the Tanakh, which is a bit surprising, and I do not accept his characterization of liberal humanism -- but it pulls together the major strands and important events of history compellingly and it ' s quite illuminating.Obviously, if you want to get compellingly illuminated, read the book....

Alveoli on a Chip to Reveal Airflow Characteristics in Disease and Drug Delivery
Researchers at the Harbin Institute of Technology in China have developed a microfluidic-style chip that models the alveoli present in our airways. The tiny air sacs in our lungs are crucial for gas exchange, but they can be difficult to study and model. A better understanding of airflow patterns in these structures could be very useful in informing the design of inhalable medications, understanding respiratory threats in the form of inhaled particulate pollutants, and also in understanding respiratory diseases. This new device models a branching point of the airways using a flexible polymer that has been molded into small...

Pneumatic Prosthesis to Reduce Pressure and Irritation for Amputees
At the University of Waterloo in Canada, researchers have developed a microfluidic-based pneumatic system that adjusts the pressure within the socket of a lower limb prosthesis. The aim is to achieve the ideal pressure and adjust the fit of the prosthesis to compensate for changes in the size of the residual limb because of swelling. Current lower limb prostheses require users to change silicone and fabric liners manually to adjust the fit of their prosthetic device. This is suboptimal, particularly in patients with diabetes who may have limited feeling in their residual limb, leading to chafing and ulceration. This new de...

Bifurcation PCI : Physics & Philosophy of kissing & crushing strategy
Bifurcation PCI is a modern-day Cardiologist’s fascinating professional adventure within coronary arteries. Of course, the Intention is to do good for the patient. Bifurcation lesions (BFL) are a special subset of lesions, that looks challenging, more because of the potential biological aftermath following the delicate construction of a grade separator at a critical site. Mind you, it’s done within a live flowing artery and subsequently needs lifelong maintenance.
