Hidden among us are survivors – living, breathing beings that have pulled off some pretty remarkable feats in order to live another day. They can be found ambling through the moss beneath our feet, drifting in our oceans and our streams, even stuck in the local pet store or on the subway. You just have to know where to look.
These creatures give clues into how we could withstand extreme conditions, regrow damaged tissue or missing limbs, turn back the hands of time, guard ourselves from illness, and perhaps even achieve humankind’s most elusive goal – immortality. Read More
Watch a fly land on the kitchen table, and the first thing it does is clean itself, very, very carefully. Although we can’t see it, the animal’s surface is covered with dust, pollen and even insidious mites that could burrow into its body if not removed.
Staying clean can be a matter of life and death. All animals, including us human beings, take cleaning just as seriously. Each year, we spend an entire day bathing, and another two weeks cleaning our houses. Cleaning may be as fundamental to life as eating, breathing and mating. Read More
It’s time to enjoy some monster stories, and the scariest monsters of all are those that actually exist.
Join us as we share tales of some of the creepiest parasites around — those that control the brains of their human hosts, sometimes leaving insanity and death in their wake. These are the tales of neurological parasites. Read More
It’s probably best to get the bad news out of the way first. The so-called scientific method is a myth. That is not to say that scientists don’t do things that can be described and are unique to their fields of study. But to squeeze a diverse set of practices that span cultural anthropology, paleobotany, and theoretical physics into a handful of steps is an inevitable distortion and, to be blunt, displays a serious poverty of imagination. Easy to grasp, pocket-guide versions of the scientific method usually reduce to critical thinking, checking facts, or letting “nature speak for itself,” none of which is really all that uniquely scientific. If typical formulations were accurate, the only location true science would be taking place in would be grade-school classrooms. Read More
It might not just be expectant mothers who have to pay attention to their lifestyle. Now a new study published in Science could be relevant to a growing body of research looking at ways in which the lifestyle and environment of men before they become fathers could influence the lives of their children and grandchildren.
We know that many human traits, such as weight, height, susceptibility to disease, longevity or intelligence, can be partly inherited, but researchers have so far struggled to identify the precise genetic basis for this. This may partly be due to limitations in our understanding of how genetics works, but now there is growing interest in the potential for something called “epigenetics” to explain this heritability.

The animal kingdom is full of color. Animals use it for camouflage, to advertise themselves and even as various forms of protection. But we haven’t been paying as much attention to what colors now-extinct mammals might have had – until now.
By matching samples of organic material to their chemical make up we’ve been able to determine the color of extinct bats and our novel research, published in PNAS, has the potential to work out colors in lots of other organisms. Read More
One evening last month, library technician Chris Weiss could be seen prowling the streets of Petersburg, Alaska, in her batmobile. She didn’t attract any special attention; the light blue Subaru blended right in. But the sensitive microphone on the roof and the bright yellow box inside the car gave her the power to hear sounds outside of human hearing – bat calls.
Weiss is part of a network of citizen scientists tallying the bats of southeastern Alaska through an Alaska Fish and Game Department project. The research is showing what a healthy bat population in the region looks like – important data on its own, but vital information if disease ultimately strikes Alaska’s bats as it has bats in the contiguous U.S.
There’s an idea circulating that humans are the only animal to experience sexual pleasure; that we approach sex in a way that is distinct from others. As with many questions about sex, this exposes some interesting facts about the way we discuss the subject.
On one level, the question of whether humans and nonhumans experience sex in the same way is fairly simply dismissed: how would we know? We cannot know how a nonhuman experiences anything – they can’t be asked. Sex as an experiential phenomenon for nonhumans is, quite simply, inaccessible. Science is obliged to propose questions that are answerable, and “how does a leopard slug experience sex?” is, at time of writing, about as unanswerable as they get.
Having said that, we can make educated guesses about whether sex is pleasurable for other species. Sex would be a very strange thing to seek if it didn’t bring some form of pleasure. It increases risk of disease, it wastes energy, it can seriously increase the likelihood of something bigger coming along and eating you (seriously, check out leopard-slug reproduction, below).
From trilobites to tyrannosaurs, most fossils are of creatures with hard shells or bones. These materials don’t easily biodegrade and sediment has time to build up around them and turn them into a record of the creature that is still with us millions of years after it has died. Soft-bodied organisms like worms, on the other hand, decay rapidly and their fossil record is decidedly patchy.
In exceptional circumstances, however, their remains are preserved and sometimes in the most unusual places. With the right detective skills, paleontologists can use such discoveries to open up whole new windows on the history of life on Earth. A recent discovery found in 50-million-year-old rocks from Antarctica has yielded a particularly incredible example: fossilized worm sperm.
It’s a great reminder that there are far stranger fossils out there than dinosaur bones. Here are some of the most bizarre specimens ever found.
I have always wondered why our species Homo sapiens, that evolved in Africa about 200,000 years ago, seemed to do nothing special for the first 150,000 years. Because it is not until about 50,000 years ago that the first sign of creative thinking emerged with beautiful cave paintings found in Spain, France and Indonesia.
Around the same time a new sub-species referred to as anatomically modern humans or Homo sapiens sapiens appears. Anatomically modern humans were more slender than their earlier ancestors; they had less hair, smaller skulls. They looked basically like us.
But these changes weren’t just cosmetic. Two recent papers throw some light on how the revolutionary development of smaller and more fine-boned humans influenced the growth of cooperative culture, the birth of agriculture and human dominance of the planet.
