Besides condoms and vasectomies, there isn’t much men can do to share the responsibility in birth control. But not for long! Now, researchers have developed a pill that can temporarily render a male mouse infertile. Is it too good to be true?
Scientists using MRI imaging to scan the brains of young men and women, find out that female brains are designed to carry out many tasks simultaneously. Male brains are designed to make them better at carrying out single tasks.
A ferrofluid is a liquid which becomes strongly magnetized in the presence of a magnetic field and looks AWESOME! This vid is just me having fun with science.
Let’s see this evolutionary ghost story. You’ll find out why the ginkgo biloba tree is so weird, visit with some prehistoric beasts, and learn how an avocado is a bit like a dodo bird.
The human brain is puzzling — it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why?
Some of the most familiar scientific breakthroughs and discoveries came while the researcher was looking for something completely different, while others were just plain luck. It always helps if you are open to the possibility of using what you’ve got as well as what you’re looking for!
Screenshot from youtube.com @univoflouisville Scientists in Kentucky predict that they’ll be able to use 3D printer technology to create a bioficial human heart in only ten years’ time. Dr. Stuart Williams is the director of the Cardiovascular Innovation Institute in downtown Louisville, Kentucky, and he thinks his office is only a decade away from what […]
Humans, octopi and pine trees alike are all made up of cells, tiny but sophisticated systems that keep life going. Cells are almost like tiny factories run by robots, with the nucleus, DNA, proteins, lipids, and vitamins and minerals all playing critical roles. George Zaidan and Charles Morton lay out the blueprint of a cell and explain how biochemistry binds all life together.
Designers working on a new generation of medical equipment that robotic surgery could soon be applied on beating human hearts.
What color is your blood. Red, right? Well, actually, yes. So why does it look blue when you see it through your skin? And is everyone’s blood always the same color red (spoiler: no)? Do all animals have red blood (‘nother spoiler: no!)? And why is red blood red anyway? Hank gives you the facts on vampires’ favorite beverage.
Trees create immense negative pressures of 10′s of atmospheres by evaporating water from nanoscale pores, sucking water up 100m in a state where it should be boiling but can’t because the perfect xylem tubes contain no air bubbles, just so that most of it can evaporate in the process of absorbing a couple molecules of […]
