Helping Identify Performance-Enhancing Drugs, Through Chemistry

(ISNS) – From steroids to uppers, sports have weathered some pretty big storms when it comes to drugs.
Matthew Stein's insight:

A research chemist has found a way to improve the detection of performance enhancing drugs in athletes. Through a method called mass specrometry, the weight of the molecules is able to be detected, which aids in the identification of the drug in question. This method, however, falls short as it cannot pick up negatively charged molecules that break up in the body. The new method is a slight change to specrometry that allows the detection of the drugs. I thought this was interesting, because it is so accurate, if a single drop of a drug was placed in 1 of 20 olympic sized swimming pools, this method would be able to detect it. This article comes from the American Institute of Physics.

Matthew Stein's insight:

As of now, screening tests to determine if someone is carrying the non-dormant bacteria form of tuberculosis has been a slow and unreliable process. Scientists in Houston have developed a new screening test that only takes 9 hours (as opposed to 8 weeks) to accurately determine if the TB bacterium is dormant or not. In a nutshell, the non-dormant TB bacteria is very small, so a small filter that can "trap" the bad bacteria is used. The sample is then tested and graphed to see if any bad bacteria is present. This article comes from a source called "Chemical and Engineering News," and the author has obtained her Ph.D in animal science and now works as a professor at NDSU. This provides evidence that this source is reliable, as the author is likely very knowledgeable in the information she is writing about.

Building a Better Battery

Building a Better Battery | Science in our changing world. | Scoop.it
As tech companies focus on small, wearable devices, they have encountered an obstacle: Battery technology is largely stuck in the 20th century.

Via David Scott Lewis
Matthew Stein's insight:

With technological advances soaring at a seemingly unstoppable rate, one drawback limits everything: The battery. With battery technology at an almost stand-still, major companies such as Google and Apple are searching for alternative forms of batteries other than the outdated lithium ion technology. These new theoretical power sources range from solar power all the way to air powered. 

This source is from the New York times, which is generally regarded as a reliable source, as a newspaper of this size would not publish articles with shoddy facts. Both authors specialize in technological journalism, and one of them has won awards for his coverage of technology.

They are working to find a better alternative to the battery. With the competition on, many different engineers have hopped on to this dilemma in search for a battery that can absorb energy from nearby objects or an efficient compact solar panel that could fit in your phone. Soon enough they could move this technology into cars and have cars that power themselves so well that we might not need the power of gasoline.

Don't let denial get in the way of a good science story
Phys.Org
Back in the 1970s when I was a young lecturer, the task communicating science to the general public was straightforward, at least in principle.
Matthew Stein's insight:

This article shows the author's frustration with some scientists that think they are superior simply because they have knowledge the general public does not. He explains different types of science,  and why it is harmful that some people are in denial about the authenticity of their findings.

Bacteria that trigger Crohn's disease identified | Science News

Bacteria that trigger Crohn's disease identified | Science News | Science in our changing world. | Scoop.it

NIdentifying the onset of Crohn’s disease may best be done by looking at bacteria in the cellular linings intestinal tissue.

Matthew Stein's insight:

For years, scientists have not been able to find any distinguishable differences between Crohn's disease sufferers and non sufferers, until now. Researchers have found more strains of the E. coli bacteria, a bacteria living in all of us in our intestines in sufferers. E. coli is the culprit for causing food poisoning when humans are exposed to it externally (food, doors handles, ect), but it is harmless when naturally inside our bodies. This breakthrough may pave the road for possible new and improved treatments for Chron's sufferers. This article was published by ScienceNews, a scientific news source. This article does not have any noticeable bias, as it is simply explaining what researchers have found in their studies.

Scientists More Certain Than Ever on Climate Change, Report Says - NBCNews.com

Scientists More Certain Than Ever on Climate Change, Report Says - NBCNews.com | Science in our changing world. | Scoop.it
Khaleej Times Scientists More Certain Than Ever on Climate Change, Report Says NBCNews.com Experts are more certain than ever that human activity is changing the global climate, even though they don't fully understand every detail of the climate...
Matthew Stein's insight:

Climate change is a serious problem. Whether people choose to believe it or not, the world is heating up, which will have serious repercussions. The author argues that even though many people are on the same basis that global warming is a real and prevalent problem, it is not on track to being solved because the highest level of governments either are unaware of the problem, or they choose to ignore it. This article might be biased as it comes from NBC, which is known to be more liberal. The author John Roach has been writing scientific articles, namely ones focusing on the environment, so aside from the possible bias of NBC, he is a credible writer on this subject.

Fusion energy milestone reported by California scientists - Washington Post

Fusion energy milestone reported by California scientists

Scientists are creeping closer to their goal of creating a controlled fusion-energy reaction, by mimicking the interior of the sun inside the hardware of a laboratory.
Matthew Stein's insight:

For the first time in history, scientists have managed to produce more energy in a reaction than the put in. This is a momentous achievement, because if physicists can perfect nuclear fusion, we would have the cleanest, and most efficient energy source possible. While this is only a drop in the bucket, scientists are slowly getting closer to their ultimate goal of perfect fusion reactors. The author of this article has been writing about sciences for the Washington Post since 1990, so this article is likely reliable.
