How We Can Harvest Wind Power From Tiny Flapping Flags


Wind energy typically conjures up images of towering turbines being revved up by massive, spinning airfoils. At a much smaller scale, however, it’s also possible to harvest wind power from the friction of flapping flags.

A study published today in Nature Communications describes an experimental generator, which builds a charge using mechanics that are similar to rubbing a balloon on your nephew’s head.

Study links changing winds to warming in Pacific


A new study released Monday found that warming temperatures in Pacific Ocean waters off the coast of North America over the past century closely followed natural changes in the wind, not increases in greenhouse gases related to global warming.

The study compared ocean surface temperatures from 1900 to 2012 to surface air pressure, a stand-in for wind measurements, and found a close match.

Hacked photosynthesis could boost crop yields


It is difficult to find fault with a process that can create food from sunlight, water and air, but for many plants, there is room for improvement. Researchers have taken an important step towards enhancing photosynthesis by engineering plants with enzymes from blue-green algae that speed up the process of converting carbon dioxide into sugars.

The results, published today in Nature, surmount a daunting hurdle on the path to boosting plant yields — a goal that is taking on increasing importance as the world’s population grows.

The Deepwater Search for the Antikythera Mechanism, the World’s First Computer


Sometime in the early first century B.C., a ship went down in the Mediterranean Sea, just off a Greek island named Antikythera. The wreck itself wasn’t unusual. The island was surrounded by jagged rocks, which likely caused many a boat to disappear back then. But there was something different about this one. The boat contained a trove of statues, jewelry, and — most notably — what some scholars believe to be the earliest computer known to man.

Mission To Study Mars' Climate Enters Red Planet's Orbit


He says when you look at aerial pictures of the Martian surface, you see unmistakable signs that Mars was once upon a time a fairly wet planet.

"We see evidence for lakes, for river channels, a lot of evidence for liquid water that required a very different climate from the one we have today," Jakosky says.

Asteroids: between a rock and a hard place


At a press conference earlier this year, former Nasa astronaut Dr Edward Lu announced that there are around 1m asteroids in the Earth's vicinity "with the potential to destroy a major metropolitan area". He teed up an animated graphic to demonstrate how unprepared we are. The graphic showed the Earth in orbit among the dangerous asteroids we knew about and were tracking, around 10,000 of them.

What's Hiding Beneath The Surface Of Kraken Mare, Titan's Largest Sea?


The largest body of liquid on Saturn's moon Titan is the formidably named Kraken Mare, a sea of methane that sprawls some 400,000 km 2 across the moon's north polar region. Next week, NASA's Cassini spacecraft will perform a flyby of Titan in search of wave activity atop this colossal sea of hydrocarbon.

Rendlesham UFO incident: Sculpture to be installed at forest site


A 'UFO' has been built to mark the spot where an alleged landing took place in one of the UK's biggest UFO mysteries.

In December 1980, there were reports of phenomena in Rendlesham Forest, Suffolk near a United States Air Force base.

Why Do People Believe in Ghosts?


Recent surveys have shown that a significant portion of the population believes in ghosts, leading some scholars to conclude that we are witnessing a revival of paranormal beliefs in Western society. A Harris poll from last year found that 42 percent of Americans say they believe in ghosts. The percentage is similar in the U.K., where 52 percent of respondents indicated that they believed in ghosts in a recent poll.

The Joe Rogan Experience with Graham Hancock, Podast #551 (JRE #551)


Here's my latest appearance on the Joe Rogan experience. Joe had a surprise in store for me about two thirds of the way through the interview. It was all very spontaneous and on the spot but I'm still thinking through the implications of my first smoke in three years!

Pacific settlers developed gardens to survive


Analysis of ancient human bones supports the idea that the first inhabitants of Vanuatu developed horticulture as they ran out of wild resources.

Around 2500 years ago there was a shift in the Lapita people towards a greater reliance on cultivated plants such as yam, taro and banana, according to an isotopic analysis of bones reported in a recent issue of PLOS ONE.

New Large Stone Prehistoric Cutting Tools Found in China


A team of scientists have uncovered large stone cutting tools (LCTs) in the Danjiangkou Reservoir Region (DRR) of central China.

The tool assemblage, discovered and analyzed by Kathleen Kuman of the University of the Witwatersrand and colleagues Chaorong Li of the Chinese Academy of Sciences and Hao Li of the University of the Witwatersrand, were excavated at a site on the southeastern edge of the Qinling Mountains.

China: Ancient Tomb of First Emperor Qin Shi Huang's Grandmother Discovered in Xi'an


A huge ancient tomb belonging to the grandmother of China's first emperor Qin Shi Huang has been found in Xi'an during excavations to expand the Xi'an University of Finance and Economics campus in Shaanxi province, northwest China.

According to China.org.cn, the tomb complex covers an area measuring 173,325 square metres, stretching 550m in length and 310 meters in width, and is the second largest tomb to have ever been discovered in the country.

They're Calling This New Species Of Hadrosaur The "King Nose"


Yes, it's got quite the schnoz — but you probably wouldn't want to mess with this giant herbivore. The recently identified species of hadrosaur measured some 30 feet long and weighed over 8,500 pounds.

Called Rhinorex condrupus, or "king nose," the dinosaur was discovered by paleontologists from North Carolina University and Brigham Young University.

Does the Bible have secrets to reveal? Scholars hope to restore hidden text in ancient New Testament


The Codex Zacynthius is regarded as a crucial text in studying the development of the New Testament.

It features a sixth or seventh century script which has been partially scraped away and written over to make way for a 13th century entry.

Now scholars are hoping to uncover this hidden script after securing over £1 million to keep it at a British university.

New Megalithic Site Could Steal Title for Oldest Stone Monument


A new megalithic site has been found in the near east and it seems to predate the pyramids of Egypt, and even Stonehenge.

A pretty exciting statement in any sense, but let’s not get ahead of things.

Well Water May Contain Earthquake Warning Signs


Spikes in sodium and hydrogen in well water warned of mounting strain before two Iceland earthquakes, geologists say.

The new study, published today (Sept. 21) in the journal Nature Geoscience, provides some of the best evidence yet for earthquake precursors. Despite centuries of effort, no one has discovered reliable precursors, which are changes seen before an earthquake. But while seismologists would dearly love to save lives by predicting earthquakes, the well-water evidence is not a first step toward early warnings — it's more like a glimpse of a long, bumpy road.
