While it’s well-known that workers in ant colonies typically support one reproductive female – a queen, it turns out that cheating can be a problem, and not…
Cornell entomologists have discovered that male and female mosquitoes (Aedes aegypti), which can spread such diseases as yellow and dengue fevers, “interact…
The method, which involves treating carbon nanotubes with fluorine-based molecules, is reported in the Jan. 9 issue of the journal Science (Vol. 323 No. 234). The research was jointly led by Graciela B. Blanchet, a research fellow at DuPont, and George Malliaras, Cornell associate professor of materials science and engineering and the Lester B. Knight Director of the Cornell NanoScale Science and Technology Facility. Helen Lu, a research chemist at Dupont, and Mandakini Kanungo, a former Cornell postdoctoral fellow now at Xerox, also worked on the project. …
The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago — trends that coincided with severe…
“To escape a predator, you don't have to be fast, you just have to be more erratic,” said Tom Eisner, a world authority on animal behavior, ecology and…
In the first study to explain the failure to control certain bed bug populations, toxicologists at the University of Massachusetts Amherst and Korea’s Seoul…
In 1913 Theodore Roosevelt added cartographer to his resume when he and his crew ventured up an unspeakably dangerous and uncharted tributary named the River…
Researchers have long known that some repetitive DNA sequences can make human chromosomes “fragile,” i.e. appearing constricted or even broken during cell…
The method, which is based on near-field microscopy, opens new avenues for analyzing mechanical properties of high-performance materials or for contact-free…
The finding reinforces what researchers have recently begun to suspect: that the age-related degeneration of tissues, organs and, yes, even facial skin with…
To compound matters, the population of this equatorial belt – from about 35 degrees north latitude to 35 degrees south latitude – is among the poorest on Earth…
The finding comes from a balloon-borne instrument named ARCADE, which stands for the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission. In…
Smooth, dark buildings, vehicles and even roads can be mistaken by insects and other creatures for water, according to a Michigan State University researcher,…
Researchers have found that a technique used to visualize amyloid fibers in the laboratory might have the potential to destroy them in the clinic. The…
An innovative approach for implanting a new aortic heart valve without open-heart surgery is being offered to patients at NewYork-Presbyterian…
A Boston University School of Medicine-led research team has discovered a more efficient way to create induced Pluripotent Stem (iPS) cells, derived from mouse…
