Placebo Effect Isn’t Just In The Head

Monday, November 9th, 2009

DoctorResearchers have shown that there is a physical basis to the placebo effect. They measured pain-related nerve activity in the spinal cord and found that it vanished when a placebo was used.

Targeting Cancer With Nanomedicine

Wednesday, October 21st, 2009

DoctorIn yet another case of science fiction becoming science fact, researchers have been working on nanoparticles that home in on cancer cells and destroy them, without damaging the rest of the body. Much, much better than chemotherapy. I hope this technology makes it to the mainstream.

The Search For Life

Sunday, October 4th, 2009

SpaceWhenever I hear an expert say that life would not be possible if some physical constant or feature of the Earth had been slightly different, I remind myself that it’s really life as we know it that would not be possible.

The Penicillin of Anti-virals

Friday, September 4th, 2009

DoctorMedical researchers have long wanted a generic anti-viral agent that works on most viruses, much like antibacterials (such as penicillin) work on bacterial infections. The main way we protect against viruses is to inject a vaccine consisting of a harmless or dead version of the virus. This causes the body to generate antibodies and allows it to react more quickly when exposed to the real virus. The problem is that this doesn’t work on new or mutated viruses (think SARS or the ever-changing flu virus).

Now researchers have developed a promising anti-viral drug that should work on most existing viruses as well as any new ones. Rather than prepping the body’s immune system, it works directly on the virus and prevents it from replicating. And as an added bonus, it will be quite difficult for a virus to develop an immunity to the drug. The linked article has more details.

Facts About Health Care Around the World

Thursday, September 3rd, 2009

DoctorChad’s News has no opinion on political issues, but given the controversy surrounding the US government’s proposed health care legislation, I thought the linked article would be helpful. It provides basic information about the existing programs in various countries (including the US).

Say Goodbye to Dentures

ScientistJapanese researchers have successfully grown replacement teeth in mice. Here’s hoping this will be a common procedure for humans when I’m old enough to need dentures.

Large Hadron Collider Update

Thursday, August 20th, 2009

Atom SmasherCERN’s super-expensive Large Hadron Collider (LHC) was shut down last September due to one badly-soldered electrical connection, with the expectation that it would be up and running this September. This will not be the case. After inspecting the entire system, technicians found 5,000 faulty electrical connections, apparently due to poor workmanship. In an effort to get something in the way of results, CERN will run the collider at half-power starting this November. Then in late 2010 it will shut down the system to make the repairs necessary for full-power usage. So it may be years before we see the ground-breaking results that were originally expected.

Gyroscopes in Zero-G

Tuesday, May 26th, 2009

ScientistThe video in the linked article is from the International Space Station, and shows the stabilizing effect of gyroscopes. The demonstration is done in zero-gravity, and the “gyroscopes” are portable CD players.

Thinking Outside the Universe

Tuesday, April 7th, 2009

SpaceThis article is one of the more readable explanations that I’ve seen of how universes are created. It’s short and concise, yet manages to cover topics from quantum multiverses to what may exist outside of our universe.
