TAU researchers discover unique non-oxygen breathing animal

Researchers at Tel Aviv University (TAU) have discovered a non-oxygen breathing animal. The unexpected finding changes one of science’s assumptions about the animal world. A study on the finding was published on February 25 in PNAS by TAU researchers led by Prof. Dorothee Huchon of the School of Zoology at TAU’s Faculty of Life Sciences and Steinhardt Museum of Natural History. The tiny, less than 10-celled… Read More

Disease found in fossilized dinosaur tail afflicts humans to this day

The fossilized tail of a young dinosaur that lived on a prairie in southern Alberta, Canada, is home to the remains of a 60-million-year-old tumor. Researchers at Tel Aviv University, led by Dr. Hila May of the Department of Anatomy and Anthropology at TAU’s Sackler Faculty of Medicine and Dan David Center for Human Evolution… Read More

Tiny insects become “visible” to bats when they swarm

Bats use echolocation to hunt insects, many of which fly in swarms. In this process, bats emit a sound signal that bounces off the target object, revealing its location. Smaller insects like mosquitos are individually hard to detect through echolocation, but a new Tel Aviv University study reveals that they become perceptible when they gather… Read More

First proof-of-concept demonstrates genetic sex selection in mammals

Certain plants, insects, crustaceans and fish possess the uncanny ability to change the sex of their offspring before they are born. Mammals have never before demonstrated this genetic skill, until now. A new Tel Aviv University study reveals a genetic system in mammals that enables two animals to mate and produce only females. A similar… Read More

Lightning’s electromagnetic fields may have protective properties

Lightning was the main electromagnetic presence in the Earth’s atmosphere long before the invention of electricity. There are some 2,000 thunderstorms active at any given time, so humans and other organisms have been bathed in extremely low frequency (ELF) electromagnetic fields for billions of years. These electromagnetic fields — the result of global lightning activity… Read More

New study a practical step towards a “green” replacement for oil

A new Tel Aviv University study specifies the first yearlong productivity rates of seaweed-borne macroalgae in Israel’s coastal waters, and the surface area required to produce mass quantities of the macroalgae in order to manufacture ethanol, a green alternative to oil. “Oil leads to wars, to pollution, to political dependency, to terrorism,” says Dr. Alexander… Read More
