• Video shows invasive lionfish feasting on new Caribbean fish species

  01-06-2017 23:29
  
  The showy lionfish, a predator with venomous spines that has invaded Caribbean coral reefs, has found a new market to exploit: the "twilight zone," an area of ocean that lies below traditional SCUBA diving depths, where little is known about the reefs or the species that inhabit them.

• Scientists release frogs wearing mini radio transmitters into Panamanian wilderness

  01-06-2017 23:26
  
  Ninety Limosa harlequin frogs (Atelopus limosus) bred in human care are braving the elements of the wild after Smithsonian scientists sent them out into the Panamanian rainforest as part of their first-ever release trial in May. The study, led by the Panama Amphibian Rescue and Conservation Project, aims to determine the factors that influence not only whether frogs survive the transition from human care to the wild, but whether they persist and go on to breed.

• A better dye job for roots—in plants

  01-06-2017 23:25
  
  Once we start coloring our hair, we may be surprised to learn that we begin to have a problem in common with plant biologists: finding the right dye for our roots. In the case of the biologists, just the right chemical is needed to measure exactly how plant roots grow. Now, a researcher at the Salk Institute has discovered a fluorescent dye that, paired with other imaging techniques, reveals root growth to be influenced by a major plant hormone more than previously thought.

• The Omentum: A Curtain of Tissue That Keeps Our Guts Working

  01-06-2017 21:14 via feedproxy.google.com
  
  A push to renew research into an understudied gut organ is gaining momentum.The organ in question? The omentum. It's a curtain of fatty tissue that hangs down from our stomach and liver and wraps around the intestines, and is known to play a role in immune responses and metabolism, although exactly how that happens is only dimly understood.Because the omentum doesn't have a discrete function like, say, our stomach, it can be easy to overlook. But, as a new review published in the jou

• Rover findings indicate stratified lake on ancient Mars

  A long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one part of the lake to another, according to a comprehensive look at findings from the first three-and-a-half years of NASA's Curiosity rover mission. While previous work had revealed the presence of a lake more than three billion years ago in Mars' Gale Crater, this study defines the lake's chemical conditions and uses Curiosity's powerful payload to determine that the lake was stratif

• Why was a teenager with bone cancer buried on Witch Hill in Panama?

  A new report by Smithsonian archaeologists and colleagues in the International Journal of Paleopathology identifies a bone tumor in the upper right arm of an adolescent who was buried in about 1300 AD in a trash heap at a site in western Panama called Cerro Brujo or Witch Hill. The reason for what appears to be a ritual burial in this abandoned pre-Colombian settlement is unknown.

• Retreating Ice Sheet Spurred Massive Methane Blowouts on the Seafloor

  01-06-2017 20:00 via feedproxy.google.com
  
  A massive reserve of methane — a greenhouse gas more potent than carbon dioxide — is trapped deep within the seafloor.In northern latitudes, thick ice sheets act as a lid sequestering gases at the right temperature and pressure. But when that ice melts, it’s akin to popping a cork on a pressurized bottle of champagne, rapidly releasing large volumes of the pent-up gas.For proof that warmer conditions can spur violent belches, a team of scientists based in Norway looked to the B

• Locked movement in molecular motor and rotor

  01-06-2017 20:00
  
  For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. University of Groningen organic chemists led by professor Ben Feringa are the first to achieve this in a molecular motor. They have produced a light driven rotary motor in which the rotary movement is locked to that of a secondary naphthalene rotor. The results will be published on 2 June in the journal Science.

• How the Galapagos cormorant lost its ability to fly

  The flightless cormorant is one of a diverse array of animals that live on the Galapagos Islands, which piqued Charles Darwin's scientific curiosity in the 1830s. He hypothesized that altered evolutionary pressures may have contributed to the loss of the ability to fly in birds like the Galapagos cormorant.

• Breaking Newton's Law: Intriguing oscillatory back-and-forth motion of a quantum particle

  01-06-2017 20:00
  
  A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton's equations of motion tell us that a moving body keeps on moving on a straight line unless any disturbing force may change its path. The impact of Newton's laws is ubiquitous in our everyday experience, ranging from a skydiver falling in the earth's gravitational field, over the inertia one feels in an accelerating airplane, to the earth orbiting ar

  Our sun was still dim. Waves crashed on martian beaches. Life was emerging on Earth.That’s when the ghosts of two dead stars — black holes dozens of times more massive than our sun — merged in a far-off corner of the universe. In their final moments, these binary black holes were circling each other hundreds of times per second, as each one spun at 10 times that rate.The rumbles of distant thunder from that collision reached Earth on Jan. 4 of this year, passing through the det

  About 75 years ago, the North American B-25 Mitchell bomber became famous as the twin-engined plane that helped the United States launch the first retaliatory attack on the Imperial Japanese homeland during World War II. The medium bombers mainly deployed in the Pacific theater of war, where they often served as low-flying gunships that attacked both land and sea targets with bombs and machine gun strafing. But not all of the bombers and their six-man crews ret

• Cities Are Bad for Bumblebees—Except Detroit

  For bumblebees, big cities are a bummer. Layers of asphalt, concrete, brick and metal add up to fewer places for the insects to nest. But one big city—Detroit—reverses that trend. That means shrinking cities might be a growing opportunity for at-risk pollinators.Bumblebees (species with the genus name Bombus) are, like other bees, in trouble.

  If our body temperature increases by even 1°C, we fell pretty sick, but Echinolittorina malaccana periwinkles routinely experience and survive temperatures in excess of 55°C. It turns out that the thermotolerant molluscs reinforce the core of proteins such as malate dehydrogenase, to prevent them from unraveling at high temperature, while increasing the flexibility of regions that are essential for the protein's mechanism to ensure that the protein remains functional at high and low temp
