Eight lambs born prematurely were kept in artificial wombs called Biobags.
After 4 weeks, the lambs’ brains and lungs developed, they grew soft fleece and even opened their eyes.
Scientists are hopeful that this technology will help save premature human babies in the future.
Science Mag writes –
Overcoming engineering, biology, and technology obstacles, a team of researchers has crafted what may be the best artificial womb yet: a fluid-filled bag in which lambs born early can live for up to 4 weeks, before being ushered into the outside world. Although others have designed similar systems that are still in animal testing, this one is notable for its stripped-down simplicity.
The result is a sealed “biobag” with one tube supplying artificial amniotic fluid and another draining it out. Although some lambs experienced complications, and human testing is, at best, several years off, the advance is generating excitement among those who care for pregnant women and their extremely premature babies.
“What they’ve got is a system where the fetus is really existing very much as it would in the mother’s womb,” says Anna David, a maternal-fetal medicine specialist at University College London (UCL). “The fetus knows what to do,” she adds, noting that as best they could, the physicians stepped aside and ceded control.
Thanks to high school, we’ve all got a pretty good idea about what’s on the periodic table.
But whether you’re looking at something common like calcium, iron, and carbon, or something more obscure like krypton and antimony, how well do you know their functions? Could you name just one practical application for vanadium or ruthenium?
Lucky for us, Keith Enevoldsen from elements.wlonk.com has come up with this awesome periodic table that gives you at least one example for every single element (except for those weird superheavy elements that don’t actually exist in nature).
There’s thulium for laser eye surgery, cerium for lighter flints, and krypton for flashlights. You’ve got strontium for fireworks, and xenon for high-intensity lamps inside lighthouses.
Oh and that very patriotic element, americium? We use that in smoke detectors.
We’ve included a sneak-peak below, but for the real interactive experience, click here to try it out.
You can also download the PDF if you’ve got a class to teach, or maybe you just want to be great and put it on your bathroom door.
And if this whole exercise has made you realise just how rusty you’ve become with your science basics, check out AsapSCIENCE’s Periodic Table Song below.
We’d like to see a better way of memorising the periodic table – it’s even got the four brand new elements that earned a permanent spot in the seventh row back in January (which unfortunately have no cool uses outside of atomic research).

For more than 250 days of 2016, Costa Rica ran entirely on renewables.
It was the second year running that the Central American country of 4.9 million people powered itself on 100% renewable electricity for more than two thirds of the year.
Over the course of 2016, renewables supplied 98.1% of Costa Rica’s electricity, slightly down from the 98.8% achieved in 2015.
On days when Costa Rica did not generate all its electricity from renewable sources, the extra capacity came from diesel-fuelled thermal power plants, a spokesman for the Costa Rican Electricity Institute (ICE) told Mashable.
As the graphic above shows, hydropower is Costa Rica’s dominant energy source, accounting for almost three quarters of electricity generation in 2016. It is followed by geothermal energy, which provided 12.74% in 2016, then wind power at 10.3%, diesel-fuelled thermal power plants at 1.88%, biomass at 0.72%, and solar power at just 0.01%.
Hydropower is currently the largest single renewable electricity source, providing 16% of the world’s electricity, according to the International Energy Agency. It’s also a relatively cheap form of energy, but there are concerns about its environmental impact – the dams required to create hydropower plants can alter ecosystems, harm fish stocks and impact the lives of local people.
Like nuclear, hydropower provides a stable base load that renewable electricity sources like wind power and solar photovoltaic are unable to match, due to their intermittency.
Indeed, countries that produce close to 100% of renewable electricity tend to share two features in common – relatively small populations, and large hydropower generating capacity relative to energy demand.
According to data from the World Bank, both Albania and Paraguay generated 100% of their electricity from hydropower in 2013.
Iceland, meanwhile, generated 100% of its electricity from renewable sources: 71% from hydropower and the bulk of the remainder from its extensive geothermal resources.
The total amount of electricity generated by Albania, Paraguay and Iceland combined in 2013 was 85.5 terawatt hours (with 60.4 terawatt hours generated by Paraguay). To put this in context, the world’s largest electricity producer, China, generated 5,422 terawatt hours over the same period – two thirds of which came from coal-fired power plants.
When hydropower is taken out of the renewable electricity mix, the proportions fall considerably from 100%:
This chart shows electricity production from renewable sources, excluding hydroelectric (% of total)
Wind power pioneer Denmark leads the way, while Iceland still performs strongly thanks to its geothermal resources.
However, these figures are from 2014, and as a result Costa Rica’s rapid growth in wind power installations are not included. The country’s investment in wind farms in recent years means it is on schedule to more than double its wind generating capacity from 194 MW in early 2015 to 393 MW in 2017.
The 10.3% of its electricity generated by wind power in 2016 meant that 23.8% of Costa Rica’s electricity in 2016 came from renewables excluding hydro – beating more than half of the top 10 countries ranked by the World Bank in 2014.
In the World Economic Forum’s Global Energy Architecture Performance Index (EAPI), Costa Rica is ranked 14th out of 127 nations.
The EAPI looks at 18 indicators covering three key areas: economic growth and development, environmental sustainability and energy access and security. Costa Rica ranks 11th for economic growth and development, 18th for environmental sustainability, and 62nd on energy access and security.

futurists that always seem to be at least five years away, may be a little closer to reality than we realize. A lot of prototypes have been showcased recently, and a lot of money is being tossed around. More people than ever seem to buy into the crazy notion that in the near future we’ll be buzzing between rooftops in private, autonomous drones. Today, Munich-based Lilium Aviation announced an important milestone: the first test flight of its all-electric, two-seater, vertical take-off and landing (VTOL) prototype.
In a video provided by the Munich-based startup, the aircraft can be seen taking off vertically like a helicopter, and then accelerating into forward flight using wing-borne lift.
The craft is powered by 36 separate jet engines mounted on its 10-meter long wings via 12 movable flaps. At take-off, the flaps are pointed downwards to provide vertical lift. And once airborne, the flaps gradually tilt into a horizontal position, providing forward thrust.
During the tests, the jet was piloted remotely, but its operators say their first manned flight is close-at-hand. And Lilium claims that its electric battery “consumes around 90 percent less energy than drone-style aircraft,” enabling the aircraft to achieve a range of 300 kilometers (183 miles) with a maximum cruising speed of 300 kph (183 mph).
In many ways, electric-powered aviation is still in its infancy. Electric cars with thousand-pound batteries generally max out at 300 miles per charge. The most sophisticated electric aircraft today can barely muster an hour aloft at 99 mph — and that’s without vertical take-off and landing. But Patrick Nathen, co-founder of Lilium Jet and the startup’s head of calculation and design, said their battery technology will get the job done.

I found this animation fascinating! Ive read the book and its always a good to look over the chapters every now and then.
Animator – “I crafted this summary of the 48 Laws of Power in anger. It is the end result of 2 years of animating all chapters condensed for your viewing pleasure. Surely, you’ve heard the phrase “Hate the game, not the player.” I’m exposing the game and the players for you.
Being honest and speaking the truth has been a punishing and not at all rewarding experience, since most people will always shoot the messenger. I aim to raise awareness and arm the clueless for self-protection. I am not advocating becoming a manipulating and ruthless sociopath.
I can’t respect those who don’t understand the difference. It’s a self-improvement book, not the work of the devil. Robert Greene is all about intense realism. Seeing things for what they are, whether you like the truth or not.
Hopefully you’ll find the video helpful, learn from it and share it with others. I’ve received plenty of messages from good people claiming it changed their lives for the better.
Don’t let others use and abuse you. Don’t live in a fantasy land. Be cautious. Read this book or don’t. It’s up to you.”

Makes you think about all this political activity ….
Despite being one of the poorest nations in the world, Afghanistan may be sitting on one of the richest troves of minerals in the world, valued at nearly $1 trillion, scientists say.
Afghanistan, a country nearly the size of Texas, is loaded with minerals deposited by the violent collision of the Indian subcontinent with Asia. The U.S. Geological Survey began inspecting what mineral resources Afghanistan had after U.S.-led forces drove the Taliban from power in the country in 2004.
In 2006, U.S. researchers flew airborne missions to conduct magnetic, gravity and hyperspectral surveys over Afghanistan. [Infographic: Facts About Rare Earth Minerals]
The aerial surveys determined that Afghanistan may hold 60 million tons of copper, 2.2 billion tons of iron ore, 1.4 million tons of rare earth elements such as lanthanum, cerium and neodymium, and lodes of aluminum, gold, silver, zinc, mercury and lithium. For instance, the Khanneshin carbonatite deposit in Afghanistan’s Helmand province is valued at $89 billion, full as it is with rare earth elements.
“Afghanistan is a country that is very, very rich in mineral resources,” geologist Jack Medlin, program manager of the USGS Afghanistan project, told LiveScience. The scientists’ work was detailed in the Aug. 15 issue of the journal Science.
In 2010, the USGS data attracted the attention of the U.S. Department of Defense’s Task Force for Business and Stability Operations, which is entrusted with rebuilding Afghanistan. The task force valued Afghanistan’s mineral resources at $908 billion, while the Afghan government’s estimate is $3 trillion. [Gold Quiz: How Much Do You Know About Gold Mining?]
Over the past four years, USGS and TFBSO have embarked on dozens of excursions to confirm the aerial findings, resulting in what are essentially treasure maps for mining companies.
The Afghan government has already signed a 30-year, $3 billion contract with the China Metallurgical Group, a state-owned mining enterprise based in Beijing, to exploit the Mes Aynak copper deposit, and awarded mining rights for the country’s biggest iron deposit to a group of Indian state-run and private companies.
