Brain size determined survival chances among large animals

Researchers at Tel Aviv University (TAU) and the University of Naples have examined the mass extinction of large animals over the past tens of thousands of years and found that extinct species had, on average, much smaller brains than species that survived. The researchers link the size of the brain (in relation to the body… Read More

Fruit bats are outstanding navigators, even by day

A new Tel Aviv University (TAU) study has found that fruit bats use their biological sonar during the day, even though their vision is excellent and would presumably eliminate the need for the bats to emit calls to the environment and use their echoes to locate objects (a process known as echolocation). The researchers believe… Read More

TAU study reveals the evolutionary reason why women feel colder than men

Researchers at Tel Aviv University (TAU) are offering a new evolutionary explanation for the familiar scenario in which women bring a sweater into work, while their male counterparts feel comfortable wearing short sleeves in an air-conditioned office: A built-in evolutionary difference between the heat-sensing systems of the two sexes, related to the reproduction process and… Read More

Though slow, seahorses can snag prey at exceptional speed

Seahorses are considered particularly poor swimmers. However, despite being relatively slow, they are adept at preying on small, quick-moving animals. Tel Aviv University (TAU) researchers have succeeded in characterizing the incredible preying capability of seahorses, discovering that they can move their heads up at the remarkable speed of 0.002 seconds. The rapid head movement is… Read More

TAU research exposes the biological basis of empathy

Can mammals other than human beings demonstrate empathy for one another, engage in pro-social behavior, and help others in distress? New Tel Aviv University (TAU) research based on an animal model using rats found that, just as with humans, rats are also split into various groups with different indicators to the point that they come… Read More

Survivability of animal species depends on the number of offspring, TAU researchers say

Researchers from Tel Aviv University (TAU) participated in a new international study proposing an amendment to the widely accepted theory on the extinction of animal species, moving the focus from the animal’s body size to its reproductive capacity. The researchers found gaps and incompatibilities between mammals and amphibians in the relation between body size and… Read More
