Astronomers have found the strongest evidence yet that ancient Mars had a massive ocean for millions of years— an indication that the Red Planet once had everything necessary to support life. Shortly after Mars formed 4.5 billion years ago, NASA scientists say, the planet was wet, with enough water to cover the entire planet to a depth of about 450 […]

Millions of years ago Antarctica was not where it is located today. It started off in the mid-latitudes and started moving about an inch to two inches a year to the bottom of the earth. The continent also had palms and baobab trees and reptiles and marsupials. The mountains, valleys and inlets are still located on the continent. Antarctica measures […]

Global warming hits plateau. . . What does that mean for the threat of catastrophic climate change? Why has the warming trend slowed? Climatologists aren’t sure. What they do know is that the average air temperatures at the earth’s surface have risen only about 0.2 degrees Fahrenheit since 1998—the hottest year of the 20th century—even as humanity has continued to […]

Japan decided to resume Antarctic whale hunt after a hiatus despite an IJC ruling, which prompted international outrage. The International Court of Justice ruled in March 2104 that Japan’s decades-old whale hunt in the Antarctic should stop, prompting Tokyo to cancel the bulk of its whaling for the 2014/2015 season. The order from the United Nations court was binding and […]

Here’s a novel idea for putting the brakes on global warming: Ask everyone in the world to paint their roofs white. U.S. Energy Secretary Steven Chu raised the idea last week at a conference in London, noting that the proposal, first put forth by researchers at Lawrence Berkeley National Laboratory in California, would reflect enormous amounts of sunlight off the […]

Children who attend schools near busy roads could see their brain development hindered by air pollution, according to a new study by Spanish scientists. Researchers in Barcelona spent a year tracking the developmental progress of more than 2,700 children ages 7 to 10 at 39 schools in the city. They found that the cognitive skills of students at schools near […]

Earth may owe its existence to the planet Jupiter. New research shows that the giant planet played a key role in the formation of the solar system by barreling through it like a cosmic wrecking ball, destroying existing planets and creating debris that coalesced into new ones, including ours. Astronomers began examining this theory after finding that virtually all of […]

Like many human families, killer whales often rely on the wisdom of matriarchs to help them endure hardships and thrive, new research has found. Male orcas usually live for about 50 years, but females often survive well into their 90s, making them one of the few mammalsthat live for decades after they stop reproducing. Marine scientists studied the behavior […]

“Knowing what a chicken looks like and what all the chickens before it looked like doesn’t help us to understand the egg,” says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and the early history of the Earth. The Earth’s lithosphere is divided into several plates that are in constant motion, and today’s geologists […]

A huge research ship costing £200 million has been commissioned, which will probe the oceans and climate of the arctic and Antarctic. They are the cruel seas where Britain’s greatest adventurers made their names. Now the territory of Scott and Shackleton, will be surveyed by a new generation of British explorers who will tackle the ‘final frontier’ of Earth’s […]
