- Why Africa's lions are rapidly disappearing
Africa's lion population has dwindled to 32,000, a nearly 70 percent decline in the past 50 years, according to a new survey by Duke University.
- NASA's Voyager 1 hits a 'magnetic highway' out of the solar system
Scientists at NASA say the unmanned Voyager 1 spacecraft has reached the edges of the solar system. They estimate in a few months to a year Voyager 1 will become the first manmade object to leave the solar system and enter interstellar space.
- Mars rover Curiosity soil analysis: why no news still isn't bad news
The Mars rover Curiosity has finished its first full soil analysis in Gail Crater, and its findings are consistent with those elsewhere on the planet. Researchers say the results form a 'baseline.'
- How old is a lobster? Check his eyestalk
The age of a lobster, or a crab or shrimp, can be determined by counting growth rings, as is done with trees. But scientists aren't sure yet how old a lobster can live to be.
- Polar ice melt accelerates
The Earth's ice sheets are melting three times faster than they were two decades ago, 47 researchers say in a recently published study. The scientists fault human-created global warming for the dramatic increase in melting.
- NASA surprised to spot ice on Mercury
NASA's Messenger probe enabled researchers to find unexpected materials frozen in Mercury's north pole. Scientists think the materials arrived via comets or asteroids that hit millions of years ago.
- Water ice found on scorching-hot Mercury
Temperatures on Mercury can reach 800 degrees Fahrenheit, but around the north pole, in areas permanently shielded from the sun's heat, NASA's Messenger spacecraft found a mix of frozen water and possible organic materials.
- Are polar ice sheets shrinking? Report offers definitive answer at last.
Numerous studies in recent years have offered different – and sometimes conflicting – views about ice sheets in Greenland and Antarctica. But a new report offers unprecedented scope.
- 'Bigfoot' is part human, claims study based on purported Sasquatch DNA
Because the Texas veterinarian has released no information at all about her findings (nor have they been examined by outside experts), it's impossible to evaluate the validity of her conclusions.
- Ancient Antarctic microbes isolated for millennia may provide clues to alien life
The findings shed light on the extreme limits at which life can live not just on Earth, but possibly alien worlds, scientists added.
- Moon rocks discovered in Minnesota, but more rocks missing
The Minnesota National Guard said it found some missing Apollo 11 moon rocks. The discovery in Minnesota now leaves 11 states, including Massachusetts, Texas and Wisconsin, still missing their Apollo 11 moon rocks.
- Scott Kelley: Longest space station sojourn will be test for Mars mission
NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko will spend an entire year aboard the International Space Station. The extended mission will help provide information about far-flung trips to asteroids and Mars.
- Galapagos Tortoise 'Lonesome George' may have had relatives after all
Genetic samples showed that some tortoises recently DNA tested were hybrids that had a parent like Lonesome George from the subspecies Chelonoidis abingdoni.
- SpaceX founder Musk eyes 'self-sustaining' Mars civilization
In Musk's vision, the ambitious Mars settlement program would start with a pioneering group of fewer than 10 people, who would journey to the Red Planet aboard a huge reusable rocket powered by liquid oxygen and methane.
- US-Russian crew chosen for yearlong space voyage
American astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko will launch on the one-year space station flight in spring 2015 and return to Earth in spring 2016.
- Climate change talks: What are the goals in Qatar?
UN talks for a new pact to curb greenhouse emissions and slow climate change are underway in Qatar. Negotiators hope to extend the Kyoto Protocol. The concentration of greenhouse gases such as carbon dioxide has jumped 20 percent since 2000, according to a U.N. report released last week
- Why greenhouse gases hit record high in 2011
Carbon dioxide, the primary greenhouse gas emitted by human activities, reached 390.9 parts per million last year, or 40 percent above the pre-industrial level, the World Meteorological Organization said. It cited fossil fuel as the primary source.
- Violent dolphin deaths: $5,000 reward to find their attackers
Violent dolphin deaths are on the rise in the Gulf of Mexico. The violent attacks on dolphins include bullet wounds and hacked off fins. Five dolphin deaths are from gunshot wounds.
- New smell discovered: It's 'olfactory white' as in white noise
New smell discovered: Scientists have created a 'white smell,' a 40-compound blend of scents in the middle of the pleasant-edible scale. The new smell was discovered by scientists in Israel.
- NASA video captures massive solar eruption
NASA spacecraft captured HD video of a giant plasma eruption on the surface of the Sun Friday. This plasma eruption is not headed toward Earth, so isn't expected to cause any communication problems. The sun is currently in the middle of an active phase of its 11-year solar weather cycle.
