Long ago, obesity and high blood pressure were signs of being a wealthy elite. But the world has progressed and now even the poorest countries can eat enough to be fat. As recently as 1980 those…

Rising temperatures will lead to a "greening" of the Arctic by mid-century, according to a new numerical model.  The greening not only will have effects on plant life, the researchers noted, but…

Chlorogenic acids, natural substances extracted from unroasted coffee beans, can help control the elevated blood sugar levels and body weight that underpin type 2 diabetes.  Joe Vinson, Ph.D. at…

Researchers visiting South Sudan identified a new genus of bat after discovering a rare specimen and determining the bat was the same as one originally captured in nearby Democratic Republic of the…

Seemingly benign differences in genetic code  can predispose people to chemotherapy-induced peripheral neuropathy, a condition that is hard to predict and often debilitating enough to cause…

Some assume that evolution only occurs gradually, over hundreds or thousands of years, but scientists have shown otherwise numerous times and now a new paper in Ecology Letters affirms that…

Now that the Higgs has been found, the current hype in popular science magazines suggests that the most pressing question in fundamental physics research is whether new particles will be found at the…

After the scramble to get out of jail, here are some questions about imprisoned shapes! In my last question, we came across parts of the so-called harmonic series 1/2 + 1/3 + 1/4 + 1/5 ... 1/n. Now,…

A couple of news stories related to NASA. One is that there will be money in the NASA FY14 budget to send astronauts to an asteroid and bring it back to (?) Earth. The other study is that NASA…

An analysis of how carbon is trapped and released by iron-rich volcanic magma offers clues about our early atmospheric evolution and also that of other terrestrial bodies. The composition of a planet…

Discovery of a new protein that controls the presence of the Vel blood group antigen on our red blood cells will make it possible to use simple DNA testing to find blood donors for patients who lack…

The world produces a lot of food, enough to feed billions more than are living right now. There is a distribution issue, which will be solved as science engineers more crops that can grow in more…

The solution to the Jailer’s Revenge question is fairly lengthy, so I think it warrants a separate blog entry. Please refer to the original question as it too is fairly long. Let’s firstly simplify…

New research hopes to create reactions necessary for industries such as pharmaceutical companies but eliminate the resulting waste from traditional methods.  Traditional methods – dating…
