Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea—famous for its capacity ...
Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection. ...
After digging holes in the Earth's crust for nearly two decades, Princeton University geoscientist Tullis Onstott is now making headlines for unearthing "worms from hell."
(PhysOrg.com) -- It seems we may have parasites to thank for the existence of sex as we know it. Indiana University biologists have found that, although sexual reproduction between two individuals is costly from an evolutionary ...
Using a tiny bloodless worm, University of Maryland Associate Professor Iqbal Hamza and his team have discovered a large piece in the puzzle of how humans, and other organisms safely move iron around in the body. The findings, ...
They can be both a blessing and a curse, and have been around since the dawn of life. Thousands of species are found from mountain tops to smoking volcanic vents on the ocean floor. They play a key role in soil biology and ...
The more complex a plant or animal, the more difficulty it should have adapting to changes in the environment. That's been a maxim of evolutionary theory since biologist Ronald Fisher put forth the idea in 1930.
It's safe to say that cilia, the hairlike appendages jutting out from the smooth surfaces of most mammalian cells, have long been misunderstood - underestimated, even.
Dramatic scenes are played out under Ralf Sommer's microscope: his research object, the roundworm Pristionchus pacificus, bites another worm, tears open a hole in its side and devours the oozing contents. The squirming victim ...
