Rethinking Parasitism

February 4, 2012

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.

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.

Psych-Man Fraud Exposed

November 5, 2011

A popular social psychologist in the Netherlands has been exposed of committing “fraud on an astonishing scale,” forging data in dozens of scientific papers for nearly a decade. The exposè doesn’t just destroy his reputation. The fraud will cause “huge damage,” said Susan Fiske, a social psychologist at Princeton University,” because “His work is very central—or was.”

Preventing Aging Through Darwin-Free Science

November 3, 2011

Will new discoveries in biochemistry lead to longer lives? There are hopeful signs that aging can be delayed, if not prevented. Whether or not that happens in our lifetimes (causing new worries for Social Security), scientists are learning amazing things about how cells work that should give us more reason for Thanksgiving.

Biomimetics to the Rescue of Science

October 10, 2011

The booming field of biomimetics (imitating nature’s designs) is fascinating not only for the amazing products it promises, but for the fresh new opportunities it provides for science and engineering. From viruses to mammals, everything in the living world is now being seen in a new light: agents of innovation that humans can learn from. Here are just a few examples in recent news, arranged in order from large to small inspirational creatures.

Human Cloning Advanced Despite Ethics

October 6, 2011

A researcher in New York obtained women’s eggs and conducted experiments on them that could lead to human cloning. While done in the name of regenerative medicine, the experiments on embryonic stem cells involved the destruction of a human embryo. This kind of experimentation raises multiple ethical concerns, but the researcher went ahead anyway, and scientific journals are hailing the advance, albeit with a palpable twinge of conscience about ethics.
