When a lonely and thirsty male zebra finch encountered a female, his thirst waned and he instead focused his attention on her, a shift reflected in the dopamine system.
A seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly’s circadian clock, Cornell research has found.
Researchers from the College of Arts and Sciences are involved in some of 14 new Multi-Investigator Seed Grants, designed to foster multidisciplinary collaborations.
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.
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.
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.
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.
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.
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.
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.
The second annual Intercampus Cancer Symposium, Oct. 11 at the Cornell College of Veterinary Medicine, will highlight the wide range of cancer research taking place at Cornell’s Ithaca campus and at Weill Cornell Medicine in New York City.
Tyler Barr learned about leadership under pressure while attending a summer program at officer candidate school as a midshipman in the Marine Corps ROTC program at Cornell.
He called it “by far the most difficult six weeks of our lives,” as he recounted sleeping and eating very little while being pushed to his physical limits.
Two operations research and information engineers, two electrical engineers and two mathematicians from Cornell have received National Science Foundation (NSF) Faculty Early Career Development Program awards.
Over the next five years, each researcher will receive up to $500,000 “to build a firm scientific footing for solving challenges and scaling new heights for the nation, as well as serve as academic role models in research and education,” according to the NSF website.
A project to develop topical therapies for skin diseases associated with DNA damage and another to investigate bone-binding polymers to relieve bone-on-bone pain for those with severe osteoarthritis are two of nine projects awarded 2018-19 Center for Advanced Technology (CAT) grants.
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.
Genes in an area of the brain that is relatively similar in fish, humans and all vertebrates appear to regulate how organisms coordinate and shift their behaviors, according to a new Cornell study.
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.
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. The DARPA Young Faculty Award program provides funding, mentoring and industry and Department of Defense contacts to awardees early in their careers.
Reducing antibiotic resistance in animals and developing a lubricating formula in joints for people suffering from arthritis are two of seven projects that received Center for Advanced Technology (CAT) annual grants.
What began as a Twitter joke between two researchers has turned into a four-year, $2.5 million National Science Foundation grant to take 3-D digital scans of 20,000 museum vertebrate specimens and make them available to everyone online.
Cornell’s Museum of Vertebrates, with 1.3 million fish specimens, 27,000 reptiles and amphibians (called herps), and 57,000 bird and 23,000 mammal specimens, is one of 16 institutions involved and promises to feature prominently in the project.
“How do we reconcile stable truth with multiple understandings of truth?” Bruce Lewenstein, professor of science communication, posed that question during an academic symposium, “Universities and the Search for Truth,” held Aug. 24 in Bailey Hall. The event was part of the celebration of Martha E. Pollack’s inauguration as Cornell’s 14th president.
