Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
On a blazing hot day in South Africa, female southern pied babblers can't think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds ...
Like so much else in nature, the human visual system has both a complex structure and functional efficiency that is difficult for scientists to replicate. The system is both a sensor and a processor, with the eyes and the ...
It's easy to take our eyes for granted. But our recent research shows they took an incredible evolutionary journey to reach their current familiar form.
By comparing osteoarthritis pain pathways known to be active in dogs and humans to those in cats with degenerative joint disease (DJD), researchers found that elevation of a particular molecule, artemin, could serve as a ...
A University of California, Riverside team of scientists has found that Toxoplasma gondii, a common parasite affecting up to one-third of the global population, is far more complex than previously believed. The findings, ...
From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.
A new study, led by the University of Vienna and the Alfred Wegener Institute in Bremerhaven, shows how the eyes of adult marine bristleworms continue to grow throughout life—driven by a ring of neural stem cells reminiscent ...
Past psychology and behavioral science studies have identified various ways in which people's acquisition of new knowledge can be disrupted. One of these, known as interference, occurs when humans are learning new information ...
What is the evolutionary advantage of our consciousness? And what can we learn about this from observing birds? Researchers at Ruhr University Bochum published two articles on this topic.
