Four elected to National Academy of Sciences

Peter Lepage, the Tisch Family Distinguished University Professor in the Department of Physics, is among four Cornell faculty to be honored this year.
Spider, seen close-up, against dark background


Orb-weaver spider uses web to capture sounds

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.

After mating, fruit fly sperm are no longer fully male

Long considered exclusively male, a new study revealed that by four days after a sperm enters a female fruit fly, close to 20% of its proteins are female-derived.

Temperature, reproduction link holds promise for insect control

Scientists have uncovered a set of neurons in fruit flies that could provide a target for controlling mosquitos.

Four assistant professors win 2022 Sloan fellowships

Assistant professors Pamela Chang, Antonio Fernandez-Ruiz, Daniel Halpern-Leistner and Peter McMahon have won 2022 Sloan Research Fellowships from the Alfred P. Sloan Foundation.

Academic Integration efforts lead to $33M in grants

Bringing researchers together – not only across disciplines but across the 200-plus miles separating Ithaca from New York City – is the aim of academic integration, which promotes, builds and enhances collaborative research across Cornell’s campuses.

CRISPR improves method for studying gene functions

A new paper describes a technique that helps biologists understand the roles that individual genes play.

Computer model reveals how cortical areas develop and evolve

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.

Sex peptide causes female fruit fly’s gut to grow

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.

Lost frogs rediscovered with environmental DNA

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.

 Small brown frog


Exclusive group mating found for first time in Brazilian frogs

The lack of previous examples of group fidelity in frogs may be simply because the behavior is hard to observe.

Antonie Blackler, pioneering biologist, dies at 88

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.



New imaging technique sheds light on adult zebrafish brain

The Cornell Neurotech team's research could have implications for the study of human brain disorders, including autism.
 Two students hold up projects in screen shots


Lab instructors adapt to remote teaching

Teaching labs remotely “gave us this opportunity to really pause and think about what are our goals for the students.”

Research interrupted: Lab groups find their way together

Faculty are helping students come up with solutions – ways they can be productive remotely, read papers and write.

Improved CRISPR gene drive solves problems of old tech

Gene drives use genetic engineering to create a desired mutation in a few individuals that then spreads via mating throughout a population in fewer than 10 generations.

 Panelist talk about coronavirus


Panel discusses global uncertainties surrounding coronavirus

With the recent emergence of the coronavirus from China’s Hubei province, another “virus” has the potential to spread, a Cornell faculty member said Tuesday at a wide-ranging panel discussion on the outbreak.
