The Afar Rift in Ethiopia is marked by enormous gashes that signal the breakup of the African continent and the beginnings of a new ocean basin, scientists think.
The fractures appear eerily similar to seafloor spreading centers, the volcanic ridges that mark the boundaries between two pieces of oceanic crust. Along the ridges, lava bubbles up and new crust is created, slowly widening the ocean basin.
But a look deep beneath the Afar Rift reveals the birth announcements may be premature. “It’s not as close to fully formed seafloor spreading as we thought,” said Kathy Whaler, a geophysicist at the University of Edinburgh in Scotland.
Whaler and her colleagues have spotted 120 cubic miles (500 cubic kilometers) of magma sitting in the mantle under the Afar Rift. Hot liquids like magma like to rise, so the discovery is a conundrum.

The ancient Romans were pretty advanced for their time — so advanced that they may even have been pioneers of what we now call nanotechnology.
In fact, an ornately decorated Roman artifact, known as the Lycurgus cup, is inspiring researchers to explore practical applications of the ancient technology.
Created sometime in the Fourth Century, the goblet exhibits a color-changing property that makes its glass take on different hues, depending on the light source — just watch the cup in the video above.
Scientists were long at a loss to explain the cup’s color changes. Then in the 1990s they discovered tiny particles of silver and gold in the cup’s glass. According to Smithsonian Magazine, “When hit with light, electrons belonging to the metal flecks vibrate in ways that alter the color depending on the observer’s position.”
Now, a research team is attempting to build upon the unique technology and apply it in the medical field.
Gang Logan Liu, an University of Illinois assistant professor who has studied the Lycurgus cup for several years, described it as an “icon for inspiration.”

The periodic table of the elements has grown ever since the first version was published by Dmitri Mendeleev in 1869. And now scientists in Sweden suggest it’s time to add yet another element to the table.
New research confirms the existence of a super-heavy, radioactive element with atomic number 115. Its temporary name is ununpentium (Uup), as the element has yet to be named formally. The research was conducted at the GSI accelerator facility near Darmstadt, Germany, where scientists are known for having discovered six other elements since the early 1980s.
“This was a very successful experiment and is one of the most important in the field in recent years,” lead researcher Dr. Dirk Rudolph, physics professor at the University of Lund in Sweden, said in a written statement.
Evidence for element 115 was first discovered by Russian scientists in 2004. But additional research now has confirmed that the element’s atomic number — the number of protons in the nucleus of one atom of the substance — is 115, BBC News reports.

Ancient Egyptian beads found in a 5,000-year-old tomb were made from iron meteorites that fell to Earth from space, according to a new study. The beads, which are the oldest known iron artifacts in the world, were crafted roughly 2,000 years before Egypt’s Iron Age.
In 1911, nine tube-shaped beads were excavated from an ancient cemetery near the village of el-Gerzeh, which is located south of Cairo, said study lead author Thilo Rehren, a professor at UCL Qatar, a Western Asian outpost of the University College London’s Institute of Archaeology. The tomb dates back to approximately 3200 B.C., the researchers said.
Inside the tomb, which belonged to a teenage boy, the iron beads were strung together into a necklace alongside other exotic materials, including gold and gemstones. Early tests of the beads’ composition revealed curiously high concentrations of nickel, a telltale signature of iron meteorites.
“Even 100 years ago, [the beads] attracted attention as being something strange,” Rehren told LiveScience.

It doesn’t look like much, but scientists from Sweden’s Uppsala University are calling a newly created form of magnesium carbonate an “impossible” material.
Dubbed upsalite, the highly porous material sets new records for surface area and water adsorption, according to a written statement issued by the university. It is expected to have all sorts of applications, from controlling moisture in processes used by the electronics and pharmaceutical industries to sopping up toxins in the aftermath of chemical and oil spills.
“In contrast to what has been claimed for more than 100 years in the scientific literature, we have found that amorphous magnesium carbonate can be made in a very simple, low-temperature process,” study co-author Johan Goméz de la Torre, a researcher in the university’s nanotechnology and functional materials division, said in the statement.

After a quarter-century of searching, scientists have nailed down how one particularly rare subatomic particle decays into something else – a discovery that adds certainty to our thinking about how the universe began and keeps running.
The world’s top particle physics lab said Friday it had measured the decay time of a particle known as a Bs (B sub s) meson into two other fundamental particles called muons, which are much heavier than but similar to electrons. It was observed as part of the reams of data coming from CERN’s $10 billion Large Hadron Collider, the world’s largest atom smasher, on the Swiss-French border near Geneva.
The rare sighting at the European Center for Nuclear Research, known by its French acronym CERN, shows that the so-called standard model of particle physics is “coming through with flying colors,” though it describes only 5 percent of the universe, said Pierluigi Campana, who leads one of the two main teams at CERN involved in the research.

An 1,800-year-old stone carving of what may be the head of a Roman god was recently found in an ancient garbage dump, British archaeologists announced today (July 3).
An undergraduate student at Durham University discovered the largely intact head during an archaeological dig at the Binchester Roman Fort, a major Roman Empire fort built around A.D. 100 in northeastern England’s County Durham.
Archaeologists involved in the dig believe that somebody probably tossed the 8-inch-long (20 centimeters) statue in the garbage when the building was abandoned in the fourth century, during the fall of the Roman Empire.
The team is still not certain who the carved head is meant to represent, though they have noted its resemblance to a similar stone head discovered in 1862 inscribed with the name “Antenociticus” — a Celtic deity associated with military prayers in that particular region.

Humans spent centuries conspiring to fly, so it might be hard to imagine that any creature would give up the skill, and yet penguins waddle among us. A new study helps confirm that these seabirds traded flight to become better swimmers.
Penguins have a litany of physical features that make them energy-efficient underwater. For instance, their shortened wingspans lessen drag; their dense wing bones make them less buoyant; and their bulky bodies help them stay insulated and dive deeper. Unlike other aquatic birds that paddle underwater with their webbed feet, penguins beat their wings to propel themselves far below the surface. Emperor penguins can even go to depths greater than 1,500 feet (450 meters), lasting 20 minutes on a single breath.
.
Murres, which resemble flying penguins, have the highest wing-loading of any bird, which results in exceptionally high flight costs and could explain why Antarctic penguins have evolved flightlessness.

Salamanders can regrow entire limbs and regenerate parts of major organs, an ability that relies on their immune systems, research now shows.
A study of the axolotl (Ambystoma mexicanum), an aquatic salamander, reveals that immune cells called macrophages are critical in the early stages of regenerating lost limbs. Wiping out these cells permanently prevented regeneration and led to tissue scarring. The findings hint at possible strategies for tissue repair in humans.
“We can look to salamanders as a template of what perfect regeneration looks like,” lead study author James Godwin said in a statement. “We need to know exactly what salamanders do and how they do it well, so we can reverse-engineer that into human therapies,” added Goodwin, of the Australian Regenerative Medicine Institute (ARMI) at Monash University in Melbourne.

Hints of dark matter, the mysterious stuff that makes up perhaps 85 percent of the matter in the universe, may have been observed by scientists.
But researchers are far from saying they’ve discovered the source of dark matter.
“We’re not claiming anything,” warned Blas Cabrera, a Stanford University physicist speaking here today (April 15) at a meeting of the American Physical Society. [Explaining Dark Matter (Infographic)]
The new results come from the Super Cryogenic Dark Matter Search (SuperCDMS), which takes place deep underground in the Soudan mine in northern Minnesota.
.
The Cryogenic Dark Matter Search experiment (SuperCDMS) uses five towers of dark matter detectors like the ones shown here.
