A star born from the same cloud of gas as our sun 4.5 billion years ago has been found at last, astronomers say.This solar sibling is a little bigger than our sun, and a little hotter at its surface. But an international team of researchers says it has the same chemical fingerprint as the star at the center of our solar system, leading them to conclude both stars were born in the same stellar nursery, at the same time.
China is planning to build a train line that would, in theory, connect Beijing to the United States. According to a report in the Beijing Times, citing an expert at the Chinese Academy of Engineering, Chinese officials are considering a route that would start in the country's northeast, thread through eastern Siberia and cross the Bering Strait via a 125-mile long underwater tunnel into Alaska.
Climate scientists have long documented the strong control of Earth's orbital variations on the waxing and waning of the great ice ages, when huge "pluvial" lakes filled the valley floors of the Great Basin.In a new study, "Orbital control of western North America atmospheric circulation and climate over two glacial cycles," published today in the online journal Nature Communications, scientists revealed a 175,000 year-long climate record from Great Basin that shows ice age temperature oscillations centered around changes in earth's orbit.

Egypt said Wednesday archaeologists have unearthed a 5,600-year-old preserved tomb and mummy predating the pharaonic First Dynasty, a discovery that will shed new light on the pre-dynastic era.The tomb was built before the rule of king Narmer, the founder of the First Dynasty who unified Upper and Lower Egypt in the 31th century BC, the antiquities ministry said in a statement.
Archeologists have found a tomb dating back to around 1100 B.C. south of Cairo, Egypt's Antiquities Ministry said Thursday.Antiquities Minister Mohamed Ibrahim said that the tomb belongs to a guard of the army archives and royal messenger to foreign countries. Ibrahim said the Cairo University Faculty of Archaeology's discovery at Saqqara adds "a chapter to our knowledge about the history of Saqqara.".
There are many mind blowing things about the pyramids, from the fact that Cleopatra lived closer to the Moon Landings than the construction of the Great Pyramid to the idea that they remained the tallest man-made structures on Earth for more than 3,800 years.However, one of the most basic and staggering facts about these colossal constructions is that they were even built in the first place. Just how did the ancient Egyptians shift stones weighing as much as 2.5-tonnes with technology no more complex than a sledge?.
Earth can serve as a giant detector for theoretical ripples in the fabric of space-time given off by stars, black holes and other massive objects in deep space, researchers say.The moon could be employed in the same way and potentially return even better results, scientists added.
As a species, human beings are obsessed with the idea that there may be aliens out there, somewhere beyond our planet.This obsession really took off in the late 19th century, when suggestions that there might be canals on Mars and popular books such as War of the Worlds by HG Wells did little to quell excitement over the chance that we might be sharing our universe with others.
The amazing supercomputer simulation in the video above takes you through 13 billion years of cosmic history, modeling the violent and dynamic processes that created the large-scale structure of our universe.As you might imagine, recreating the entire universe in a computer is a bit of a challenge, mainly because of the huge range of scales that relevant processes happen at.Related Discussion on the AoM board
Plant life may touch down on Mars in 2021.Researchers have proposed putting a plant-growth experiment on NASA's next Mars rover, which is scheduled to launch in mid-2020 and land on the Red Planet in early 2021. The investigation, known as the Mars Plant Experiment (MPX), could help lay the foundation for the colonization of Mars, its designers say.
When Apollo astronauts stood on the moon and looked back at the Earth, they were the first humans to see our planet as a completely isolated system, bounded on all sides by the endless black of space. Now, 45 years later, "Earthlight," a documentary produced by the University of Arizona College of Agriculture and Life Sciences, explores the challenges facing the human race and how the technology scientists are designing to return to the moon might be the key to humans' sustainable presence on Earth.
The mysterious vanishing of honeybees from hives can be directly linked to insectcide use, according to new research from Harvard University. The scientists showed that exposure to two neonicotinoids, the world's most widely used class of insecticide, lead to half the colonies studied dying, while none of the untreated colonies saw their bees disappear.
Guide dogs stop you bumping into things, assistance dogs can pull your clothes out of the washing machine. But medical detection dogs can keep you alive.These dogs have been specially trained to smell several cancer types. Others can gauge the blood sugar levels in diabetics, warn allergic owners away from peanuts, or detect when people with narcolepsy are about to fall asleep.
Polar bears appear to be genetically superior to humans when it comes to warding off heart disease, a new study on the hefty animal finds. What's remarkable is that polar bears are among the most fat-obsessed beasts in the animal kingdom."The life of a polar bear revolves around fat," according to Eline Lorenzen of University of California, Berkeley who worked on the study published today the journal Cell.
PICTURE the scene: a weak leader is struggling to hold onto power as ambitious upstarts plot to take over. As tensions rise, the community splits and the killing begins. The war will last for years.No, this isn't the storyline of an HBO fantasy drama, but real events involving chimps in Tanzania's Gombe Stream National Park. A look at the social fragmentation that led to a four-year war in the 1970s now reveals similarities between the ways chimpanzee and human societies break down.
The medieval Black Death led to better health for future generations, according to an analysis of skeletons in London cemeteries.Tens of millions of people died in the epidemic, but their descendants lived longer and had better health than ever before, a study shows.
The genes of 894 men and women over the age of one hundred in Spain and Japan have revealed that the secret to longevity, at least in southern Europe, lies in a variant on chromosome 9p21.3, which had already been associated with the risk of cardiovascular disease. Centenarians live at least fifteen years longer than the average person in the West.
Villagers in west Sri Lanka have said they have been surprised and delighted by an unusual rainfall of small fish.The edible fish fell during a storm and are believed to have been lifted out of a river during a strong wind.Villagers in the district of Chilaw said they heard something heavy falling and found scores of fish with a total weight of 50kg (110lbs).
Songbirds are restless creatures, and scientists have learned to take advantage of that trait to study their migration. In one famous experiment, researchers place a bird in a cage equipped with sensors. When night falls, the bird jumps in the direction in which it would normally migrate, allowing researchers to determine where it would like to go. But in 2004, in a German lab at the University of Oldenburg, the classic experiment failed miserably.
Drugs are the most common psychiatric treatment for depression. But about 40 percent of people fail to respond to this first-line of antidepressants. What to do? The answer to date has often been more and different drugs.But transcranial magnetic stimulation (TMS), a technique that can revive activity in neurons in the brain's prefrontal cortex using an electromagnet, has been receiving more attention as a possible treatment for these stubborn cases of depression.
When cancer progresses and spreads to the bone, patients often suffer debilitating pain. Now, a new phase III clinical trial shows that non-invasive magnetic resonance guided focused ultrasound treatment that heats the cancer within the bone, relieves pain and improves function for most patients when other treatment options are limited.
In less than two decades, scientists predict we'll have awesome supercomputer that can perform a trillion billion operations per second - 300,000 times more than computer's today.The only minor problem is, they would use more electrical energy than the world can currently produce.
Looking at a smooth sheet of plastic in a laboratory, no one would guess that an impact had recently blasted a hole through it. Researchers have developed materials that not only heal, but regenerate. Until now, self-repairing materials could only bond tiny microscopic cracks. The new regenerating materials fill in large cracks and holes by regrowing material.
Polar scientists said Thursday they had successfully drilled a 2,000-year-old ice core in the heart of Antarctica in a bid to retrieve a frozen record of how the planet's climate has evolved.The Aurora Basin North project involves scientists from Australia, China, France, Denmark, Germany and the United States who hope it will also advance the search for the scientific "holy grail" of the million-year-old ice core.
The rapid warming and melting of the Arctic is only half our fault. While our greenhouse gas emissions are clearly a factor, the record melts of the past few decades are partly the result of huge waves of warm air emanating from the Pacific Ocean.Related: East Antarctica melt could cause a global coastal destruction
Scientists are using 'spycams' as a cheap, accurate way to watch over Australia's native forests and woodlands as they come under increased pressure from climate change, feral animals and bushfires.Using cameras to capture images of trees at specific time intervals, researchers are developing a detailed view of how Australia trees respond to environmental stress.
Mars One has trimmed its list of prospects for one-way trips to Mars by a third, going from a pool of 1,058 candidates to 705.More than 350 hopefuls were eliminated due to medical or personal reasons, the Dutch-based venture said Monday in a news release.
The SETI project scientists are known for tracking possible extraterrestrial signals, but now they are also considering sending messages from Earth telling of our position. A researcher from the University of Cádiz (Spain) questions this idea in view of the results from a survey taken by students, revealing the general level of ignorance about the cosmos and the influence of religion when tackling these matters.
A University of Utah-led team discovered a "hypervelocity star" that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million mph, the star may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious "dark matter" surrounding the galaxy, astronomers say.
The aurora is more than just a breathtaking display of light. It may also hold the secret of a magnetic phenomenon related to the nuclear fusion powering the sun. This secret could even help create nuclear fusion in the lab, says a team of researchers.Nuclear fusion is a reaction that combines the nuclei of two atoms into one. The process powers stars, but getting a self-sustained fusion reaction going on Earth is very difficult, and has so far eluded scientists.
For people who study such tiny objects as protons, neutrons, quarks, and gluons, particle physicists do things big. They belong to teams of collaborators that comprise hundreds; they work in laboratories that extend for miles; and they generate thousands of terabytes of data. Yet these grand behaviors are not acts of bravado; rather, they are performed out of necessity.
When a team of researchers from the University of Delaware traveled to Africa two years ago to search for exemplary chickens, they weren't looking for plump thighs or delicious eggs. They were seeking out birds that could survive a hotter planet.The researchers were in the vanguard of food scientists, backed by millions of dollars from the federal government, racing to develop new breeds of farm animals that can stand up to the hazards of global warming.
By reversing its aging process when it gets sick or injured, Japan's tiny Turritopsis dohrnii jellyfish is one of the only known animals that has figured out how to defeat death. Motherboard paid a visit to Japan to visit a researcher who is studying the microscopic animal to see if humans can eventually do the same.
Dolphins are the most diverse family of living marine mammals and include species such as the bottlenose dolphin and the killer whale. However, their early evolution and fossil record has been steeped in mystery due to lack of good specimens.
Ancient giant crocodilians killed dinosaur prey by spinning their bodies in "death rolls," tearing off the beasts' flesh and limbs, researchers say.These new findings shed light on the way ancient reptiles interacted with their environments, scientists added.
A study that has 'weighed' hundreds of dinosaurs suggests that shrinking their bodies may have helped the group that became birds to continue exploiting new ecological niches throughout their evolution, and become hugely successful today.An international team, led by scientists at Oxford University and the Royal Ontario Museum, estimated the body mass of 426 dinosaur species based on the thickness of their leg bones. The team found that dinosaurs showed rapid rates of body size evolution shortly after their origins, around 220 million years ago.
Along with our big brains and upright posture, thick tooth enamel is one of the features that distinguishes our genus, Homo, from our primate relatives and forebears.A new study, published May 5 in the Journal of Human Evolution, offers insight into how evolution shaped our teeth, one gene at a time.
Yawning frequencies of people vary with temperature of the seasonCommon belief is that yawning helps to increase the oxygen supply. However, previous research has failed to show an association between yawning and blood oxygen levels. New research by a team of researchers led by Psychologist Andrew Gallup of SUNY College at Oneonta, USA now reveals that yawning cools the brain.
In 2002, two men savagely attacked Jason Padgett outside a karaoke bar, leaving him with a severe concussion and post-traumatic stress disorder. But the incident also turned Padgett into a mathematical genius who sees the world through the lens of geometry.Padgett, a furniture salesman from Tacoma, Wash., who had very little interest in academics, developed the ability to visualize complex mathematical objects and physics concepts intuitively.
Chimpanzees have almost the same personality traits as humans, and they are structured almost identically, according to new work. The research also shows some of those traits have a neurobiological basis, and that those traits vary according to the biological sex of the individual chimpanzee.
Eyes and wings are among the most stunning innovations evolution has created. Remarkably, these features have evolved multiple times in different lineages of animals. For instance, the avian ancestors of birds and the mammalian ancestors of bats both evolved wings independently, in an example of convergent evolution. The same happened for the eyes of squid and humans. Exactly how such convergent evolution arises is not always clear.
Plants have chemical defenses against infestation. Sometimes, infested plants release volatile chemicals that signal other, non-infested plants to build up defenses of their own. Koichi Sugimoto and his colleagues at Yamaguchi University in Japan studied this plant-plant signaling system in tomatoes. They found that tomato plants infested with cutworms release a volatile chemical that healthy, neighboring plants use to create a pesticide.
Plant life may touch down on Mars in 2021.Researchers have proposed putting a plant-growth experiment on NASA's next Mars rover, which is scheduled to launch in mid-2020 and land on the Red Planet in early 2021.

A vast project to map neural connections in the mouse retina may have answered the long-standing question of how the eyes detect motion. With the help of volunteers who played an online brain-mapping game, researchers showed that pairs of neurons positioned along a given direction together cause a third neuron to fire in response to images moving in the same direction.
Faced with the choice of having to do without one of their five senses, most people consider the sense of smell dispensable. Many scientists believe that the sense of smell is a relic of evolution and attribute little importance to it. This belief is reflected in the fact that many languages do not have a dedicated repertoire for describing smells.
Significant evidence now exists for the importance of sound in prehistory and research in this area has progressed over the past 30 years, with a number of archaeological finds that are thought to be musical instruments found in caves associated with palaeolithic occupation. Particularly well known are bone flutes of Aurignation date some 35-40,ooo years old and fairly advanced examples of an aerophones (bull roarers) from the same period. This shows the complex nature of instruments, yet surviving artefacts are not the sole method of examining prehistoric sounds.
The melting of a rather small ice volume on East Antarctica's shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come. These findings are based on computer simulations of the Antarctic ice flow using improved data of the ground profile underneath the ice sheet.
Wild finches in the Galapagos Islands "self-fumigate" by using a human-made pesticide to kill parasitic fly maggots, a study in the latest issue of Current Biology reports.Birds, like the rest of us, like to be the boss. Instead of treating maggot-infested nests directly, biologists are setting out pesticide-treated cotton balls, which finches are grabbing as material for building nests.
Human-made rock formations in Peru are older than famed Nasca lines.Ancient residents of Peru laid down lines of rocks in the coastal desert that may have pointed to the sites of trade fairs, a new study suggests. The features date to around 300 B.C., centuries ahead of the famed Nasca lines.
Offering hopes for tracing the family secrets of the ancient pharaohs, more than 50 royal mummies have emerged in Egypt's Valley of the Kings from a tomb long sealed by rubble and little suspected of harboring royalty.
Four deposits of artifacts possibly buried as a ritual act of sorts before the construction of a tomb have been discovered in Egypt's Valley of the Kings.The so-called foundation deposits, arranged in a boxlike shape, contain a mix of artifacts, including the head of a cow, a vase painted in blue and flint blades that have wooden handles that are still preserved after more than three millennia.
A Wiltshire town has been confirmed as the longest continuous settlement in the United Kingdom.Amesbury, including Stonehenge, has been continually occupied since BC8820, experts have found.
Neanderthal cooking likely wouldn't have won any prizes on Top Chef, but a paleontologist suggests that our ancient cousins knew how to cook a mean stew, without even a stone pot to their name."I think it's pretty likely the Neanderthals boiled," said University of Michigan paleontologist John Speth at a recent meeting of the Society for American Archaeology in Austin, Texas. "They were around for a long time, and they were very clever with fire.".
Bacteria from Earth could quickly colonize the surface of Mars, according to new research conducted aboard the International Space Station (ISS).Research into bacterial colonization on the red planet was not part of the plan to terraform the alien world ahead of human occupation. Instead, three teams investigated how to prevent microbes from Earth from hitching a ride to the red planet aboard spacecraft.
A Florida airline pilot who was outside with family in Sunrise exiting a Bruce Springsteen concert reported watching a "large, pulsating, bright white light" that changed shape and color and conducted maneuvers in the sky before moving away at "tremendous speed," according to May 3, 2014, testimony in Case 55981 from the Mutual UFO Network (MUFON) witness reporting database.
Moons in close binary solar systems have a better chance of hosting life than those in single-star systems, new research has shown.Binary stars dampen each other's solar radiation and stellar winds, thereby creating a more hospitable environment for life and increasing the habitable zone around such solar systems, according to research presented at the 223rd American Astronomical Society meeting in January.
A new discovery in the study of how lava dome volcanoes erupt, published today in Nature Geoscience, may help in the development of methods to predict how a volcanic eruption will behave, say scientists at the University of Liverpool.Volcanologists at the University have discovered that a process called frictional melting plays a role in determining how a volcano will erupt, by dictating how fast magma can ascend to the surface, and how much resistance it faces en-route.
African fork-tailed drongos mimic the alarm calls of a range of other local bird species to trick their neighbours into leaving their food unattended over and over again, a new study has found.The drongos (Dicrurus adsimilis) belong to a group of animals known as kleptoparasites, which make a living by stealing food caught by other species.

BioGenFutures, a new company-cum-art-project launched by information artist Heather Dewey-Hagborg, hopes to bring DNA surveillance back to the fore. The company just announced a product it calls "Invisible," which endeavors to make it harder for authorities to trace left-behind DNA evidence back to people.
You couldn't say the crime is being committed by stealth. Quite the contrary: Tom Wheeler, the chairman of the Federal Communications Commission, is aiming to slay net neutrality in broad daylight. The murder weapon is a proposal to allow Internet service providers to charge content companies more for faster access to their subscribers.
How would you fancy being a mobile weather station? Rolf Hut, from Delft University of Technology in The Netherlands, plans to turn our umbrellas into rain gauges.His prototype smart brolly has a sensor that detects raindrops falling on its canvas, and uses bluetooth to send this information via a phone to a computer.
Many children who are bullied suffer in silence. But there may be a way to identify victims of bullying before they suffer serious, long-term mental health problems, according to a recent study.Researchers from the University of Warwick in the United Kingdom found that nightmares or night terrors could be a signal of a child being bullied. They found that nightmares were more common in 12-year-olds who had reported being bullied when they were 8 and 10 years old.

Leonard da Vinci was the original Renaissance man, dabbling in not just art, but anatomy, geology, botany, cartography, mathematics, literature and much, much more. Not only do we give him credit for masterpieces like "The Last Supper" and "The Vitruvian Man," history praises his work in musical instrument construction, hydraulics, cannon design and early flying machines.
The US space agency's Curiosity Mars rover has drilled another hole on the Red Planet.It is almost a year since the robot last turned the power tool in the ground.
Although more than 1,000 exoplanets have been discovered since the first one was found in 1995, only a handful of those are thought to be habitable, at least by life as we know it. New research shows that exomoons, too, could provide habitable environments.Related: Search for extraterrestrial life clouded by exomoon atmospheres
For the first time, astronomers have measured the length of a day on a planet beyond our own solar system, and it's a fast one. They say one day on Beta Pictoris b takes just eight hours, due to a rotation rate that's more than 50 times faster than Earth's.
The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon's makeup.Previously, the moon was thought to harbor a thick ocean sandwiched between just two layers of ice, one on top and one on bottom.
