Could Anti-Radiation Drug Protect Us On Earth…And Mars?

Posted by in categories: biological, space

If humanity ever meets lifeforms beyond Earth (or discovers our solitude in our galaxy) one thing will be sure–galactic historians will remark how interesting it must have been living in the nuclear age that “we now enjoy” (assuming we survive of course).

Speaking of nuclear, it seems that some scientists are utilizing a new drug that is showing major promises of fighting against radiation exposure, ensuring that victims not only survive, but remain “semi-healthy” as well.

(Space War) But now researchers at Washington University School of Medicine in St. Louis report they have developed an agent that protects cells from the lethal effects of radiation, regardless of whether it is given before or after exposure.

Using this agent in mice, the investigators found that the treatment helped shield rapidly dividing cells that are most vulnerable to radiation-induced death, providing proof in principle that it is possible to fend off radiation damage, according to a study published in the April issue of Biochemical and Biophysical Research Communications.

US flu control strategy flaws and suggested improvements

Posted by in categories: biological, defense, existential risks

In a report to be published in the peer-reviewed journal PLoS Computational Biology and currently available online, Sally Blower, a professor at the Semel Institute for Neuroscience and Human Behavior at UCLA, and Romulus Breban and Raffaele Vardavas, postdoctoral fellows in Blower’s research group, used novel mathematical modeling techniques to predict that current health policy — based on voluntary vaccinations — is not adequate to control severe flu epidemics and pandemics unless vaccination programs offer incentives to individuals.

According to the researchers, the severity of such a health crisis could be reduced if programs were to provide several years of free vaccinations to individuals who pay for only one year. Interestingly, however, some incentive programs could have the opposite effect. Providing free vaccinations for entire families, for example, could actually increase the frequency of severe epidemics. This is because when the head of the household makes a choice — flu shots or no flu shots — on behalf of all the other household members, there is no individual decision-making, and adaptability is decreased.

While other models have determined what proportion of the population would need to be vaccinated in order to prevent a pandemic, none of these models have shown whether this critical coverage can actually be reached. What has been missing, according to Blower, a mathematical and evolutionary biologist, is the human factor.

Decisive, immediate action can reduce Pandemic Deaths

Posted by in categories: biological, defense, existential risks, lifeboat

Cities that quickly closed schools and discouraged public gatherings had fewer deaths from the great flu pandemic in 1918 than cities that did not, researchers reported on Monday. Experts agree that a pandemic of some virus, most likely influenza, is almost 100 percent certain. What is not certain is when it will strike and which virus it will be.

In Kansas City, no more than 20 people could attend weddings or funerals. New York mandated staggered shifts at factories. In Seattle, the mayor told people to wear face masks.

No single action worked on its own, the researchers found, it was the combination of measures that saved lives. Peak death rates can be 50% to eight times lower. St. Louis authorities introduced “a broad series of measures designed to promote social distancing” as soon as flu showed up. Philadelphia downplayed the 1918 flu.

Philadelphia ended up with a peak death rate of 257 people per 100,000 population per week. St. Louis had just 31 per 100,000 at the peak.

2007 DARPA Military Technology Plan: Future Medical Promise or Danger?

Posted by in categories: biological, biotech/medical, defense, lifeboat, robotics/AI

DARPA (the defense advanced research projects agency) is the R&D arm of he US military for far-reaching future technology. What most people do not realize is how much revolutionary medical technology comes out of this agency’s military R&D programs. For those in need of background, you can read about the Army & DARPA’s future soldier Landwarrior program and its medtech offshoots as well as why DARPA does medical research and development that industry won’t. Fear of these future military technologies runs high with a push towards neural activation as a weapon, direct brain-computer interfaces, and drones. However, the new program has enormous potential for revolutionary medical progess as well.

It has been said technology is neutral, it is the application that is either good or evil. (It is worth a side-track to read a discussion on this concept)

The Areas of Focus for DARPA in 2007 and Forward Are:

  1. Chip-Scale Atomic Clock
  2. Global War on TerrorismUnmanned Air Vehicles
  3. Militarization of Space
  4. Supercomputer Systems
  5. Biological Warfare Defense
  6. Prosthetics
  7. Quantum Information Science
  8. Newton’s Laws for Biology
  9. Low-Cost Titanium
  10. Alternative Energy
  11. High Energy Liquid Laser Area Defense System

the potential for the destructive use of these technologies is obvious, for a a complete review of these projects and the beneficial medical applications of each visit docinthemachine.com
