Iron is a micronutrient for plants. Biologists from the Institute of Botany at Heinrich Heine University Düsseldorf (HHU) describe in a study, which has now been published in the Journal of Cell Biology, that regulatory proteins for iron uptake behave par

Chromatin is a unique DNA and protein complex that makes up the chromosomes. Specific proteins (histones) wind up the DNA like small cable drums to package the long DNA. A cable drum (consisting of four pairs of histones) with coiled DNA is called a nucle

A small international team of animal behavior researchers has found that species of glass frogs whose males help care for offspring tend to have smaller testes than species whose males do not help care for offspring. In their study, published in the journ

A multi-institutional team of archaeologists and paleontologists has unearthed and identified a new species of mammal from the Maastrichtian age. In their paper published in the journal Scientific Reports, the researchers note that the mammal was much lar

Human cells contain ribosomes, a complex machine that produces proteins for the rest of the body. Now the researchers have come closer to understanding how the ribosome works.

An international team of scientists from China, the U.S. and Europe has studied new fossils of the marine reptile Dinocephalosaurus orientalis. This research has made it possible to fully describe the bizarre, very impressive animal for the first time.

In 1934, American entomologist Elwood Zimmerman, then an undergraduate student at Berkeley, participated in the "Mangarevan expedition" to Polynesia. Among the samples he collected were three tiny (4 mm long), orange-brown solitary bees found on

A new artificial intelligence (AI) tool that draws logical inferences about the function of unknown proteins promises to help scientists unravel the inner workings of the cell.

Two natural scientists at Macquarie University, working with an evolutionary specialist at the University of New South Wales, all in Australia, have found that imperfect mimicry in spiders and insects is likely mainly shaped by adaptive processes rather t

Skywalker gibbon couples wake up each morning and sing to each other, their voices echoing across the forest canopy of their home. The primate's endearing love song helped scientists confirm what was formerly a strong hunch: Myanmar has the largest popul

Communities of microorganisms at the bottom of polar lakes evolved independently from other regions, influenced by the particular geological, biological, and climate history of their regions. The unique character of the microbial communities underscores t

Red nets are better at keeping away a common agricultural insect pest than typical black or white nets, according to a new study. Researchers have experimented with the effect of red, white, black and combination-colored nets on deterring onion thrips fro
