Two recent entries in the evolution literature have application to one sex or the other.
Follow the Leader: Plants and Animals

Need solutions to engineering problems? Look no further than the plants and animals around you. That's what more and more scientists are doing.
Stem Cells Getting Healthier

Over the past decade, stem cells have been a hot news item. Here are some late breaking news stories about them.
We Became Human by Mistake
May 5, 2012
A new theme in human evolution is making the rounds. According to the story, a mistake led to the human brain, and the rest is history.
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.
Humans Evolved from Dogs
February 10, 2012
A new finding shows dogs performing better on one kind of intelligence test than chimpanzees. If evolution teaches that human intelligence is the main trait separating us from other animals, and dogs are smarter than apes, shouldn’t the conclusion be that dogs are closer on the family tree? If not, is it valid for evolutionary biologists to pick and choose the traits that matter?
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.
Living Surprises, Living Hopes

Here are ten recent discoveries about plants and animals that are surprising and inspiring. Some of them may lead to technologies that can improve our own lives.
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.
SETI Finds Intelligent Humans
January 15, 2012
The Search for Extra-Terrestrial Intelligence (SETI) is 50 years old this year. SETI’s latest scientific discovery was the detection of a human-made satellite in Earth orbit. In a sense, this counts as a success: the detection of a signal of intelligent origin from an extra-terrestrial source (beyond terra firma). The false alarm helped calibrate the instrumentation, but did little to garner support for the effort to find aliens. The SETI Institute was all SETI-ready to party hardy at the 50th anniversary of Frank Drake’s first search, but instead, found itself struggling to keep its doors open after a severe shortfall of private funds, highlighting questions about the scientific status of the long-shot project.
Tilt-A-World: Another Constraint on Habitability
January 12, 2012
Did you ever ride a Tilt-A-Whirl, one of those cheap carnival rides that makes you dizzy and sick? Our planet would be like that if its inclination were out of control. Without tilt stability, a new study reveals, we wouldn't be sick, we'd be dead, or never alive in the first place. It's not enough to be in the Habitable Zone. Would-be inhabited planets need to avoid a new problem, called “tilt erosion.”
Body Talk
January 7, 2012
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.
Nature Does It Right

Scientists and engineers continue to find well-designed features in living things that are worth imitating.
Chinks in the Scientific Method
December 29, 2011
V & V. That’s shorthand in project design for “validation and verification.” Does the scientific method provide V & V? We are all taught to think that peer review, publication and replication help science to be self-checking, so as to avoid error. Some recent articles show that ain’t necessarily so. It may sound good in theory, but in practice, the ideal doesn’t always match the real.
