Why You Are Waterproof
April 29, 2012
Can you imagine inflating like a water balloon every time you jumped in a swimming pool? Or what if water leaked out of your skin every time you drank a glass of water? Your skin forms an impermeable barrier to water, a new study found, because of a unique way certain molecules are arranged.

Parasitism is bad. Parasitism is evil. Parasites wage war against innocent hosts. This is our mindset. What if parasites can do good? This change of heart seems to be happening for one case, the case of transposable genetic elements. If they are only doing harm to the host, why did some biologists find that “positive selection” seems to be maintaining them? That makes it sound like the cells need them.
Liberal Bias Detected in Science Media
January 19, 2012
Incredible as it sounds, the science news media seem to have a liberal bias. This is astonishing, considering the vast majority of science professors in academia are Democrats. The following examples illustrate this trend that came to light around 1859.

Scientists sometimes just prove the obvious, like that men and women are different. If we can talk body without talking bawdy, there are some new discoveries about body works that should put a spring in your step today about how your body works.
Good Science Requires Good Ethics
December 16, 2011
Science is conducted by humans for humans. It is not done in a vacuum. Even the lone researcher working in a basement hopes to make a discovery worth sharing. The need for ethical science shows most clearly when humans experiment on humans – with or without their consent. Two recent articles underscore the indispensability of moral grounds for science, and a third raises questions about the source of morality.
The Science of Thanksgiving
November 24, 2011
Should science tread into areas of virtue? Here’s how a science news entry begins: “Rather than rolling your eyes when it’s your turn to bow your head and give thanks, try being grateful. The result just might be good for you. From boosting your mood to improving your relationships, research shows that being thankful is […]
Animal Plan: It Works Well
November 10, 2011
There were Greek and Roman naturalists who were intrigued by what they saw in the living world, but their observational tools were limited to their five senses. Modern science has expanded our senses far beyond the capabilities known just a century ago. We are privileged to live in an age of discovery that is revealing even more wonders beneath the surface of living things, wonders worth knowing about. Here are just a few.
Your Copper Pipes
November 8, 2011
Each of us is part metal. Our bodies contain iron, copper, zinc, magnesium, manganese, vanadium, molybdenum, selenium, and even nickel like the coins in our pockets or purses. Unlike the other common elements of life (carbon, oxygen, hydrogen, calcium, nitrogen, phosphorus), our metals are not synthesized and recycled, but must be imported and handled with care. Copper is a good example of a biological metal that performs multiple useful functions – that is, unless something goes wrong with the machinery handling it.
