Scientists have discovered well-preserved frozen woolly mammoth fragments deep in Siberia that may contain living cells, edging a tad closer to the "Jurassic Park" possibility of cloning a prehistoric animal, the mission's organizer said Tuesday.

Russia's North-Eastern Federal University said an international team of researchers had discovered mammoth hair, soft tissues and bone marrow some 328 feet (100 meters) underground during a summer expedition in the northeastern province of Yakutia.

A rapidly worsening water shortage threatens to destabilize the planet and should be a top priority for the U.N. Security Council and world leaders, a panel of experts said in a report Monday.

The world's diminishing water supply carries serious security, development and social risks, and could adversely affect global health, energy stores and food supplies, said the report titled "The Global Water Crisis: Addressing an Urgent Security Issue."

There's enough wind to power the world many times over, according to a study out Monday, but it would take a massive infrastructure investment to harness it that analysts say is not realistic.

As the world seeks to lessen its reliance on fossil fuels like coal and natural gas, renewable energy sources like wind and solar power are being developed as alternatives.

U.S. researchers have uncovered part of what's happening, on a cellular level, to make cocaine addicts going cold turkey feel so bloody awful, according to a study published Monday.

The results provide a better understanding of what's creating that crashing low of withdrawal -- and may offer a clue for researchers looking to mitigate the symptoms and keep the user from relapsing.

The announcement two months ago that physicists have discovered a particle consistent with the famous Higgs boson cleared a formal hurdle on Monday with publication in a peer-reviewed journal.

Two laboratories working at the European Organization for Nuclear Research (CERN) had jointly announced on July 4 they had detected a new fundamental particle in experiments at the Large Hadron Collider near Geneva.

India's national space organization has marked its 100th mission by launching French and Japanese satellites.

The Indian Space Research Organization said Sunday's launch of a French observation satellite and a Japanese microsatellite was a success.

Instead of a warm, wet and possibly life-bearing planet as some scientists contend, early Mars may have been a hostile and volatile place with frequent volcanic outbursts, a study said Sunday.

Earlier research had theorised that certain minerals detected on the surface of the Red Planet indicated the presence of clay formed when water weathered surface rock some 3.7 billion years ago.

Scientists in Switzerland and the United States on Sunday said they had created a "nano-velcro" textile that offers a swift, sensitive and low-cost way of detecting mercury, a toxic and accumulative pollutant, in water and fish.

The fibres are made out of gold nanoparticles that are coated with compounds called hexanethiol and alkanethiol, and bind to charged particles, also called ions, of heavy metal elements.

The boxy little white and blue vehicle draws plenty of curious stares as it chugs down the street. But this is no golf cart -- it's Gaza's first hand-built electric car.

It is the latest creation of Munther al-Qassas, a 32-year-old taxi driver from Gaza City who was looking for a novel way to get around as the tiny Palestinian enclave goes through its worst fuel crisis yet.

NASA's Curiosity rover has temporarily halted its journey across the surface of Mars as it tests the tools on its robotic arm, the U.S. space agency said Thursday.

The $2.5 billion craft -- which landed in Gale Crater on the Red Planet on August 6 -- has covered more than a football field's distance since it began trundling eastward.
