We've known for some time that plants respond to one another, but only now are we realising how subtle and sophisticated their interactions can be. Plants continually eavesdrop on each other's chemical chatter - sometimes sympathetically, sometimes
To confirm that hydrogen was present within the magnesium, the researchers observed the nanoparticles through the world's most powerful transmission electron microscope, the TEAM 0.5 – also located at Berkeley Lab.
he discovery comes from an atom smasher called the Tevatron at the Fermilab physics laboratory in Batavia, Ill. Inside the accelerator there, particles are ramped up to near the speed of light as they race around a 4 mile (6.3 km) ring. When two part
Using DNA evidence, migration patterns, measurements of reforestation after an ice age, and calculations of planetary warming, scientists have deduced that the mysterious disappearance of the Woolly Mammoths about 4,000 years ago was chiefly due to e
Researchers recreated conditions after the Big Bang and found that time only travels one-way. During 2010, world-famous physicist Stephen Hawking proclaimed time travel possible. Now two electrical engineers, Igor Smolyaninov and Yu-Ju Hung, both fro
The dangerous supervolcano that once destroyed much of what's now the USA is much bigger than vulcanologists previously thought. That's the disturbing information confirmed by an important new study published in the prestigious journal of Geophysic
Over the years many theories have been offered. Some thought the dinosaurs grew big because of the richer oxygen content in the atmosphere. But the evidence only supports that theory for insects like the prehistoric centipedes and dragonflies. Others
Variations in electrical conductivity reveal the volcanic plume of partly molten rock But it shows the conductive part of the plume dipping more gently, at an angle of perhaps 40 degrees to the west, and extending perhaps 640 km (400 miles) from e
Storytelling has always been an art, but do we know anything about its science? Darpa is going out on a limb to explore that very question later this week, in a workshop snappily entitled “Neurobiology of Narratives.”
Among dinosaurs, the biggest of the big is Argentinosaurus. This long-necked, puny-headed creature is a member of a group of giants called sauropods. This particular extinct creature measured as much as 140 feet (43 meters) long and weighed up to 90
In a little more than an hour, they would start detonating their explosives, generating seismic waves that would be recorded by seismometers buried throughout these sandy hills and positioned on the floor of the Salton Sea.
Take a look at this chart. What we have is a clear thirty year rise in earthquake activity starting around 1960 and then dropping of for a decade. The last decade it has returned to the secular uptrend and has now made up for any lost ground. Thus
An invisible force is creating giant ripples in the Earth's crust – in a geological blink of an eye BRYAN LOVELL likes to show his fellow geologists an image of a network of river valleys. "I ask them where they think this might be on Earth," h
Local politics -- schools, zoning, council elections -- hit us where we live. So why don't more of us actually get involved? Is it apathy? Dave Meslin says no. He identifies 7 barriers that keep us from taking part in our communities, even when we tr
Ten years ago, letters laced with anthrax killed five people. The FBI says it traced the spores to a single U.S. scientist. But could the feds have gotten the wrong man?
So where did these mysterious giants come from? What were they like? And what drove them to extinction? Biologists have been arguing over these questions ever since Cuvier's time. In the past few years, however, a wealth of new information has emerg
AAPS is commercializing muon geotomography, which relies on the detection of cosmic ray muons (highly energetic electron-like particles created in the upper atmosphere) which penetrate deep within the earth. “The underground muon sensor system is abl
Now NASA has detected an incredible cosmic blast in the center of a far distant galaxy located more than 3.8 billion light years away from Earth. A light year is the distance that light, traveling at 186,000 miles per second, travels in one year: nea
The physics world was abuzz with excitement over the findings, which could offer clues to the persistent riddle of mass and how objects obtain it -- one of the most sought-after answers in all of physics.
Amazed physicists at the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab) in Illinois have announced the possible discovery of a "new force of nature." The discovery goes beyond the elusive, so-called "God Particle" tha
Large swamp-dwelling dinosaurs—like the Brachiosaurus—had heads that floated on the water and sucked up their food like massive vacuum cleaners. So declare two scientists that compare the physiology of the gigantic brutes to the bulky, noisy househol
Some paleontologists have spent careers tromping around many of the most inhospitable places on Earth seeking the elusive perfect dinosaur fossil. Now a workman—a busy oil sands worker in Alberta, Canada—literally bumped into the momentous discovery:
The research indicates that "iceberg transport and melting have a role in the distribution of phytoplankton in the Weddell Sea," which was previously unsuspected, said John J. Helly, director of the Laboratory for Environmental and Earth Sciences
Not really but this chart gives the potentially hazardous asteroids known of today (PHA) that the earth may one day have to encounter! When we look up into the sky we see some of the planets some of the time, the moon, the sun and if the sky is cl
The findings illustrate events in primate evolutionfrom ancient to recent and clarify numerous taxonomic controversies. Ongoing speciation, reticulate evolution, ancient relic lineages, unequal rates of evolution and disparate distributions of geneti
Physicists claim that the underlying reality of everything is the quanta. Now it seems that evidence has emerged that even humanity's sense of smell is linked to quantum physics. Researcher Luca Turin, of the Massachusetts Institute of Technology (M
The Earth’s mantle is the part of the planet that lies between the crust and the iron ball at its center, and to reach it, would require drilling down from a position in the ocean, because the crust is much thinner there. Even still, it would mean dr
The new study shows, however, that major portions of the temperature fluctuations can be explained equally well by local climate changes in the southern hemisphere. The variations in the Earth's orbit and the inclination of the Earth have given d
Shepherds today still exist. Unlike their European counterparts centuries ago, however, many of the today's American herders are tending human-sheep hybrids with human hearts, brains, livers, and a potpourri of other homo-sapiens attributes. The Gre
A study by a Chicago university sociologist of 1,200 women found that large-breasted women tend to have higher intelligence. The study divided the women into five groups ranging from virtually flat-chested to extra-large breasts. The results revealed
