Tiny, thin microtubes could provide a scaffold for neuron cultures to grow so that researchers can study neural networks, their growth and repair, yielding insights into treatment for degenerative neurological conditions or restoring nerve connections after injury.
When munched by grazing animals (or mauled by scientists in the lab), some herbaceous plants overcompensate – producing more plant matter and becoming more fertile than they otherwise would. Scientists say they now know how these plants accomplish this feat of regeneration.
Researchers report in the journal Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new avenues of research into thousands of similar molecules, many of which are likely to be medically useful.
A new study finds that most U.S. adults fail to meet recommended daily levels of 10 key nutrients, and those with disabilities have even worse nutrition than average.
When bad weather strikes or illness invades, zoos and aquariums are among the most vulnerable facilities affected, said University of Illinois veterinarian Yvette Johnson-Walker, a clinical epidemiologist who contributes to emergency response training efforts at animal exhibitor institutions.
They help fish swim, but fins also advertise a fish’s social standing and health. In a new study, researchers report that for the male bluefin killifish (Lucania goodei), each colorful fin presents its own messages to other fish.
