Jellies Reveal Clever Mode of Transport, Even in Absence of Brains

ENVIRONMENT & CLIMATE Without fins or bones capable of paddling, in terms of appearances, jellyfish may seem like mere drifters of the sea. But even in spite of their major deficits, including the absence of a heart and brains, these invertebrates have an incredible talent for swimming. So much so that no other creature under the sea can quite compete in terms of efficiency and skills. Though their tactics have long been misunderstood, a new study adds to the working knowledge that these brainless creatures are far more clever than we give them credit for.

Reptile Preceding Dinosaurs Discovered

Paleontologists have discovered a new species of reptile after putting together the remains of a new crocodile-like species that lived long before dinosaurs roamed the Earth.

NASA Researchers Resolve Every Star in New Panoramic View of Andromeda

While a new view of the the "Pillars of Creation" from the Eagle Nebula (Messier 16) was revealed this last Monday, Jan. 5 for the 225th meeting of the American Astronomical Society, researchers at NASA have revealed an even brighter sight from a bird's-eye view. Publishing their latest images from the Hubble Space Telescope, researchers at NASA are proudly displaying the largest Hubble image ever assembled in a stunning wide-angle view of the Andromeda galaxy next door.

VIDEO—Jellyfish Reveal A Knack for Global Positioning & Swimming in New Study

While jellyfish may seem like an innocuous marine species, most commonly known for their ability to sting, a new study published in the journal Current Biology reveals that the little gelatinous creatures are actually quite efficient in traversing waves, and can also detect the direction of ocean currents to effectively swim against them. Like a character straight out of Oz, without a heart, bones and even a brain, these little creatures may seem like their helpless in the wild but they’re proving that they can swim against the currents life brings them.

Revealing the Swimming Secrets of the Ageless, Brainless Jellyfish

They may lack brains, bones, and even a heart, but jellyfish are undoubtedly some of the most interesting creatures marine biologists have come to research. Even in spite of their major deficits, and their obvious downfalls, jellyfish have an incredible talent for swimming. So much so that no other creature under the sea can quite compete in terms of efficiency and skills. Though their tactics have long been misunderstood, a new study adds to the working knowledge that these brainless creatures are far more clever than we give them credit for.

Comet Awakes As It Approaches the Sun

Do you remember that comet we landed on last year? It seems this comet has unexpectedly become more active showing signs of "waking up" as it zooms towards the sun at almost 47,800 miles per hour.

Doomsday Clock Moves Even Closer to Midnight

The world could be closer to coming to an end, if you believe the Bulletin of Atomic Scientists who moved the clock two minutes closer to midnight. The clock now sits at three minutes to midnight making this the closest it has been to midnight since 1984 during the height of the Cold War between the U.S. and the Soviet Union.

"Living Fossil" Frilled Shark Comes Up From Ocean Depths

A rare frilled shark was caught off the coast of Australia in a fishing trawler. This rarely spotted living fossil dates back 80 million years with a face that won't win it any beauty contests and looks like something that might come out of a Hollywood horror movie.

Greenland's Massive Ice Sheets Reveal New Lakes Below

Scientists have discovered changes in the subglacial lakes that have formed below the massive Greenland ice sheet. These lakes could make the ice more sensitive to changes in the climate than many previously believed.

New Island Created By Volcano in Tonga

The Earth continues to change its landscape right before our eyes. A volcanic eruption in Tonga has created a new island, but one scientist says it could soon vanish just as quickly as it formed.

Follow-Up on the Alien Radio Transmissions and What they Could Mean for Researchers? Finding Stellar remnants far after the blast

For the first time, astronomers have been able to pick up and observe a fast radio burst in real time as it moves through space. Though little is know about these radio bursts, which are short and sharp flashes of radio waves coming from an unknown source, researchers hope that this new live transmission may help them soon be able to pinpoint sources of cosmic transmissions.

Sitting Kills, Even if You Exercise

One of the best things you do after a hard day's work or after exercising may actually be killing you. A new study running in the Annals of Internal Medicine has found that sitting for extended periods of time increases your chances of a premature death, even with exercise.

Stress Could Be Why We Don’t Empathize

Most people are able to feel empathy for a friend or loved one who is experiencing physical or emotional pain. But it is often far more difficult to experience this same feeling when it is a stranger.

Fertilizers Pose a Threat to the Future of Our Planet

While the concept of feeding our flora may seem innocuous, the use of fertilizers on our crops could be destroying the planet. A new study published in the journal Science by researchers from the University of Wisconsin reveals that excessive use of artificial fertilizers, which contain phosphorus and nitrogen, could pose a threat to the future of planet Earth.
