An orb-weaver spider perched in the hub of its wheel-shaped web. The “claw” at the tip of each leg is “hooked” gently onto strategically placed strands of web silk and positioned to “listen” to the miniscule vibrations induced by sound waves that pass through the web.
A study of orb weaver spiders finds their massive webs act as auditory arrays that capture sounds, possibly giving spiders advanced warning of incoming prey or predators.

Little is known about how higher cortical areas in the brain develop after the primary areas are in place. A new study by Cornell and Yale researchers, including professor emerita of psychology Barbara Finlay, uses computer modeling to show that the development and evolution of secondary visual cortical areas can be explained by the same process.
Scientists have known that females of many species eat more to meet the demands of reproduction, and that females undergo widespread physiological and behavioral changes after mating. The mechanisms of these changes, however, are not well understood.
Scientists have detected signs of a frog listed extinct and not seen since 1968, using an innovative technique to locate declining and missing species in two regions of Brazil.

Antonie Blackler, professor emeritus of zoology and an expert on developmental biology, died June 3 in Ithaca. He was 88. He was known for groundbreaking fundamental work on the origin of sex cells in vertebrates. His experiments with African claw-toed frogs yielded important insights into the development and reproduction of amphibian embryos, with implications for other animals and humans.

Cornell researchers have discovered there is a division of labor among immune cells that fight invading pathogens in the body.The study, published June 14 in the journal Cell, finds for the first time that fetal immune cells are present in adults and have specialized roles during infection. In fact, the first immune cells made in early life are fast-acting first responders to microbes in adulthood.

President Martha E. Pollack has committed the university to a new multi-institution initiative to make public data pertaining to career outcomes for life sciences doctoral students and postdoctoral researchers.
When honeybee colonies get larger, common sense suggests it would be noisier with more bees buzzing around.But a study recently published in Behavioral Ecology and Sociobiologyreports that bigger honeybee colonies actually have quieter combs than smaller ones.
Maren Vitousek, assistant professor of ecology and evolutionary biology, has received a two-year, $500,000 Defense Advanced Research Projects Agency (DARPA) Young Faculty Award to study links between stress, social connectedness, health and future performance.

Very little is known about the wiring of nerve cells in the brain that allow a fish, or any animal, to make fundamental choices to move to the left or to the right. A study of zebrafish larvae published Aug. 9 in the journal eLife for the first time reveals a circuit that determines the direction of a lightning-quick turn to escape a predator.
When it comes to the birds and the bees, frogs are remarkably diverse: They do it in water, on land and on leaves.Researchers have assumed that natural selection drove frogs to take the evolutionary step to reproduce on land as a way for parents to avoid aquatic predators who feed on the eggs and tadpoles.
In recent years, Cornell has amassed an impressive stable of experts in an emerging field for modern times: The ecology and evolution of infectious disease.

The idea of introducing a novel gene into a few individuals that then spreads through an entire population sounds like a premise for science fiction. And yet fiction can be prophetic.Cornell researchers have used mathematical models to illuminate the promises – and potential problems – of a new genome editing mechanism, called a gene drive.
William Provine, the Andrew H. and James L. Tisch Distinguished University Professor Emeritus at Cornell, died Sept. 1 due to complications from a brain tumor at his home in Horseheads, New York.
