Crocodiles 168 Times More Dangerous Than Sharks

General, Nature

The fears connected with shark attacks are stronger in the world today than those related to much more dangerous predators – crocodiles. However, crocodiles pose a greater threat to humans than sharks do.

A crocodile snatched Hendrik Coetzee, a South African guide, 35, from his kayak while he led an American expedition into the heart of Congo last week. Two American tourists could only watch the scene in horror as the guide was killed and eaten by the predator. They paddled to safety unharmed. Coetzee’s body has not been recovered.

Stories about croc attacks are just as terrible as they are hopeless. Experts say that it is possible to stay to fight off a shark, but it is much more difficult or even impossible to rescue themselves from an attacking croc. (more…)

Atomic Weights of Ten Chemical Elements About to Change

Science

For the first time in history, a change will be made to the atomic weights of some elements listed on the Table of Standard Atomic Weights of the chemical elements found in the inside covers of chemistry textbooks worldwide.

The International Union of Pure and Applied Chemistry’s (IUPAC) Commission on Isotopic Abundances and Atomic Weights is publishing a new table that will express atomic weights of ten elements as intervals, rather than as single standard values. The new table is the result of cooperative research supported by the U.S. Geological Survey, IUPAC, and other contributing Commission members and institutions. (more…)

Ice-Age Reptile Extinctions Provide a Glimpse of Likely Responses to Human-Caused Climate Change

Environment, Nature

ANN ARBOR, Mich. — A wave of reptile extinctions on the Greek islands over the past 15,000 years may offer a preview of the way plants and animals will respond as the world rapidly warms due to human-caused climate change, according to a University of Michigan ecologist and his colleagues.

The Greek island extinctions also highlight the critical importance of preserving habitat corridors that will enable plants and animals to migrate in response to climate change, thereby maximizing their chances of survival.  (more…)

A new study conducted by scientists at the Southwest Research Institute in Boulder, Colorado, has this week posited that Saturn’s rings are the remnants of a massive moon that once orbited Earth’s distant neighbour.

According to study author and astronomer Robin Canup, the moon plunged into Saturn around 4.5 billion years ago due to a giant ring of hydrogen gas responsible for creating rocky satellites but also for dragging larger moons out of orbit.

The scientific theory centres on the predominantly icy composition of Saturn’s rings, The Tech Herald reports. (more…)
