Guys, this is not a drill. Antarctic scientists need you to study photos of penguins to help them figure out how climate change is affecting these stumpy little flightless birds.
Scientists from the UK have installed a series of 75 cameras near penguin territories in Antarctica and its surrounding islands to figure out what’s happening with local populations. But with each of those cameras taking hourly photos, they simply can’t get through all the adorable images without your help.
“We can’t do this work on our own,” lead researcher Tom Hart from the University of Oxford told the BBC, “and every penguin that people click on and count on the website - that’s all information that tells us what’s happening at each nest, and what’s happening over time.”
The citizen science project is pretty simple - known as PenguinWatch 2.0, all you need to do is log on, look at photos, and identify adult penguins, chicks, and eggs in each image. Each photo requires just a few clicks to identify, and you can chat about your results in the website’s ‘Discuss’ page with other volunteers.

It’s a cute little thing though.
The Okeanos Explorer has discovered a very cute octopus at a depth of 4,290 metres.
This is the deepest an octopus of this particular sub order of octopus has ever been seen.
The National Oceanic and Atmospheric Administration noted this is a completely unsubscribed species and perhaps not belonging to any specific genus. Highlighting how little we still know about the creatures in the depths of our oceans.

Morocco has switched on what will be the world’s largest concentrated solar power plant. The new site near the city of Ouarzazate could produce enough energy to power over one million homes by 2018 and reduce carbon emissions by an estimated 760,000 tons per year, according to the Climate Investment Funds (CIF) finance group.
As His Majesty Mohammed VI of Morocco pressed a button on 4 February 2016, the first phase of the three-part project was set in motion.
The solar plant, called the Noor complex, uses concentrating solar power (CSP) which is more expensive to install than the widely used photovoltaic panels, but unlike them, enables the storage of energy for nights and cloudy days.
Mirrors focus the sun’s light and heat up a liquid, which, when mixed with water, reaches around 400 degree Celsius. The steam produced from this process drives a turbine and generates electrical power.
A cylinder full of salt is melted by the warmth from the mirrors during the day, and stays hot enough at night to provide up to three hours of power, according to World Bank, who partially financed construction of the plant through a $97 million loan from the Clean Technology Fund.
“The returns on this investment will be significant for the country and its people, by enhancing energy security, creating a cleaner environment, and encouraging new industries and job creation,” said Marie Francoise Marie-Nelly, World Bank Country Director for the Maghreb.

Scientists have sequenced the entire genome of the tardigrade, AKA the water bear, for the first time. And it turns out that this weird little creature has the most foreign genes of any animal studied so far – or to put it another way, roughly one-sixth of the tardigrade’s genome was stolen from other species. We have to admit, we’re kinda not surprised.
A little background here for those who aren’t familiar with the strangeness that is the tardigrade – the microscopic water creature grows to just over 1 mm on average, and is the only animal that can survive in the harsh environment of space. It can also withstand temperatures from just above absolute zero to well above the boiling point of water, can cope with ridiculous amounts of pressure and radiation, and can live for more than 10 years without food or water. Basically, it’s nearly impossible to kill, and now scientists have shown that its DNA is just as bizarre as it is.
So what’s foreign DNA and why does it matter that tardigrades have so much of it? The term refers to genes that have come from another organism via a process known as horizontal gene transfer, as opposed to being passed down through traditional reproduction.
Horizontal gene transfer occurs in humans and other animals occasionally, usually as a result of gene swapping with viruses, but to put it into perspective, most animals have less than 1 percent of their genome made up of foreign DNA. Before this, the rotifer – another microscopic water creature – was believed to have the most foreign genes of any animal, with 8 or 9 percent.
But the new research has shown that approximately 6,000 of the tardigrade’s genes come from foreign species, which equates to around 17.5 percent.
“We had no idea that an animal genome could be composed of so much foreign DNA,” said study co-author Bob Goldstein, from the University of North Carolina at Chapel Hill. “We knew many animals acquire foreign genes, but we had no idea that it happens to this degree.”

The Jehol Biota is the ecosystem of the Yixian and Jiofotang Formations of northeastern China, dating between 133 and 120 million years ago in the Early Cretaceous (from the Valanginian to Aptian ages).
It is famous because of it’s method of preservation - there were ash eruptions periodically, and the fossils are Lagerstätten, meaning that they were exceptionally well preserved with articulated skeletons, soft tissues, stomach contents, and even coloration.
This has led to an amazing understanding of various types of dinosaurs and other prehistoric animals, especially very birdy dinosaurs.
These animals lived in forests around lakes, dominated by conifers but featuring the earliest flowering plants - Archaefructus, which may have been a water plant.

There were dry seasons, but it was a mostly wet formation, as many of the plants grew in very wet habitats and probably stayed close to bodies of water.
The Yixian Formation was the older of the two main Jehol Formations, and featured many, many animals. Of invertebrates, there were spiders, crustaceans, dragonflies, flies, wasps, many other insects, and molluscs, of too many to list. Fish included the lamprey Mesomyzon, ray finned fishes such as Lycoptera, Peipiaosteus, Protopsephurus, Sinamia, and Yanosteus, and a potential shark. There were frogs and toads like Callobatrachus, Liaobatrachus, and Mesophryne, as well as a salamander, Liaoxitriton.

There were mammals, too, of course - the stem-placental Acristatherium, the stem-marsupials Akidolestes, Maotherium, Zhangheotherium, and Sinodelphys, the stem-therian (Therians being the group of Marsupials and Placentals) Eomaia, the multituberculate (a group of mammals which seem to also be stem-therians) Sinobaatar, and a significant number of Eutriconodonts, a group of early derived mammals, including Chaoyangodens, Gobiconodon, Jeholodens, Juchilestes, Meemannodon, Repenomamus, and Yanoconodon.

There were the weird early derived Saurians (the group consisting of Lepidosauromorphs and Archosauromorphs, so Extant Reptiles), Choristoderans - Hyphalosaurus, which is known from thousands of specimens, and Monjurosuchus. Lizards included Dalinghosaurus, similar to the modern Chinese Crocodile Lizard; Liushusaurus and Yabeinosaurus, lizards relatedx to modern geckos and skinks, and Xianglong, a gliding lizard. Turtles included Manchurochelys and Ordosemys, both Cryptodirans, a group including giant tortoises, sea turtles, tortoises, snapping turtles, and others.

The heroes of the formation were, of course, the Avemetatarsalians. There were many pterosaurs - Beipiaopterus, Boreopterus, Cathayopterus, Elanodactylus, Eosipterus, Feilongus, Gegepterus, Gladocephaloideus, Haopterus, Moganopterus, Ningchengopterus, Pterofiltrus, and Zhenyuanopterus.

Ornithischians included the ornithopods Bolong, Jeholosaurus, and Jinzhousaurus, the ankylosaur Liaoningosaurus, and the ceratopsians Liaoceratops and Psittacosaurus. There were sauropods too - the titanosauriform Dongbeititan, a potential titanosaur, and an animal that has for now been referred to Euhelopus. But the real heavyweights were the theropods.
Jeholosaurus by @ryuukibart
There were the tyrannosauroids Yutyrannus - one of the best known tyrannosauroids with feathers - and Dilong; the compsognathus Huaxiagnathus, Sinocalliopteryx, and Sinosauropteryx - the first non-avian dinosaur known to have feathers, and also with known coloration; early Ornithomimosaurs such as Hexing and Shenzhousaurus; the early derived maniraptoran Yixianosaurus; Beipiaosaurus, a therizinosaur; and tons of Chickenparrots, such as Similicaudipteryx, Protarchaeopteryx, Ningyuansaurus, Incisivosaurus, and Caudipteryx.

There were many Dromaeosaurids (raptors), such as Graciliraptor, Tianyuraptor, Zhenyuanlong - a raptor known from nearly complete feather traces, including extremely large wings - and Sinornithosaurus, the first Dromaeosaurid found with feathers. There were also lots of Troodontids, such as Sinusonasus, Sinovenator, and Mei, as well as unnamed members of both groups. There were early-derived Avialans such as Zhongornis, Jixiangornis, Confuciusornis, and Changchengornis. There were loads of Enantiornithines, such as Bohaiornis, Eoenantironis, Dalingheornis, Liaoningornis, Longirostravis, and Shanweiniao - an Enantiornithine that had a tail fan like modern birds. There were also Euornithines - the group which contains modern birds - such as Longicrusavis, Hongshanornis, and Archaeorhynchus. In short, this was an extremely birdy formation indeed.

The Jiuofotang Formation was slightly younger, but was similar to the Yixian in terms of the animals there. There were ray finned fishes such as Jinanichthys, Lycoptera, Peipiaosteus, Protsephurus, and Sinamia. There was the mammal Liaoconodon, a Eutriconodont, as well as an unnamed mammal similar to Eomaia from the Yixian Formation. There were also Choristoderans like Philydrosaurus, Ikechosaurus, and Liaoxisaurus.

There were many, many, many pterosaurs. This included Chaoyangopterus, Eoazhdarcho, Guidraco, Ikrandraco, Jidapterus, Liaoningopterus, Liaoxipterus, Linlongopterus, Nemicolopterus, Nurhachius, Shenzhoupterus, and Sinopterus. And, as we shall see, there were a lot of flying theropods as well, indicating that the two groups did live alongside one another just fine, and the common narrative of “birds replaced pterosaurs” has little foundation in the fossil record.

There were only a few Ornithischians - namely Chuanqilong, an ankylosaur, and Psittacosaurus, a ceratopsian. There is also an unnamed titanosaur from the formation. As for theropods, there were a lot. The tyrannosauroid Sinotyrannus was the largest predator there, there was the Chickenparrot Similicaudipteryx, and of course one of the most famous raptors, Microraptor, which was a four-winged Dromaeosaurid that we know had iridescent black feathers.
Microraptor by @artisticthingem
There were many early derived Avialans, such as Confuciusornis, Dalianraptor, Omnivoropteryx, Sapeornis, Shenshiornis, Zhongjianornis, and my personal favorite, Jeholornis, a theropod we know was a seed-eater, which is actually quite hard to determine from fossils. There were many Enantiornithines, such as Alethoalaornis, Boluochia, Cathayornis, Cuspirostrisornis, Dapingfangornis, Eocathayornis, Gracilornis, Huoshanornis, Largirostrornis, Longchengornis, Longipteryx, Rapaxavis, Xiangornis, and one of my favorites, Sinornis, which is thought to have perched. As for Euornithines, there was Chaoyangia, Jianchangornis, Parahongshanornis, Schizooura, Songlingornis, Yanornis, and Yixianornis.

It’s plain to see why the Jehol Biota is so fascinating. At least for me, I love it because it’s clearly one of the best pictures we have of Pennaraptoran evolution - the amount of birdie dinosaurs is absolutely ridiculous. But there’s really something for everyone here - there are titanosaur-like things, some of the earliest Ceratopsians, tons of Pterosaurs, weird Choristoderans, and even some insights into the evolution of early mammals and different types of amphibians and fish, as well as the first flowering plants. The Jehol Biota is one of the best ecosystems we know about, and it definitely deserves celebration!

In an attempt to unravel bacteria’s remarkable adaptive abilities, the late UC San Diego theoretical physicist and chemist Eshel Ben-Jacobs also stumbled upon a new form of art.
Ben-Jacobs grew species of bacteria in his lab and exposed them to stresses such as temperature changes, antibiotics and food scarcity in an effort to understand how they behave and cope under different environmental conditions.
What resulted were formations that indicate the different ways bacterial colonies communicate, react and make decisions about where to expand in a petri dish.
While the colors are his artistic addition, “the strikingly beautiful organization of the pattern reflects the underlying social intelligence of the bacteria,” said Ben-Jacobs.

NASA logo. March 13, 2016 NASA astronaut and one-year crew member Scott Kelly will retire from the agency, effective April 1. Kelly joined the astronaut corps in 1996 and currently holds the American record for most time spent in space. After retiring, Kelly will continue to participate in the ongoing research related to his one-year mission. He will provide periodic medical samples and support other testing in much the same way that his twin brother, former astronaut Mark Kelly, made himself available for NASA’s Twins Study during his brother’s mission. “This year-in-space mission was a profound challenge for all involved, and it gave me a unique perspective and a lot of time to reflect on what my next step should be on our continued journey to help further our capabilities in space and on Earth,” Kelly said. “My career with the Navy and NASA gave me an incredible chance to showcase public service to which I am dedicated, and what we can accomplish on the big challenges of our day. I am humbled and excited by new opportunities for me to support and share the amazing work NASA is doing to help us travel farther into the solar system and work with the next generation of science and technology leaders.”
Image above: NASA astronaut Scott Kelly inside the cupola of the International Space Station, a special module that provides a 360-degree viewing of the Earth and the station. Image Credit: NASA. Kelly flew in space four times, beginning with space shuttle Discovery’s trip to NASA’s Hubble Space Telescope on the STS-103 servicing mission in 1999. On his second mission, STS-118, he crossed the threshold of the International Space Station for the first time as commander of space shuttle Endeavour. He returned to the station for a six-month stay in 2010, commanding Expedition 26. A veteran of spaceflight, Kelly accepted the opportunity to participate in NASA’s unprecedented yearlong space station mission, which aimed to expand the boundaries of space exploration beyond low-Earth orbit through the collection of critical data on how the human body responds to extended space missions. On this mission, Kelly eclipsed two American space records. “Records are meant to be broken,” Kelly said. “I am looking forward to when these records in space are surpassed.” Kelly broke the American record for most cumulative time in space during his one-year mission, accruing 520 days. “Scott’s contributions to NASA are too many to name,” said Brian Kelly, director of Flight Operations at NASA’s Johnson Space Center in Houston. “In his year aboard the space station, he took part in experiments that will have far-reaching effects, helping us pave the way to putting humans on Mars and benefiting life on Earth. His passion for this work has helped give hundreds of thousands of people a better understanding of what NASA does, thanks in part to the numerous photos and updates he shared from space. We appreciate his years of service and anticipate many benefits to come from them, thanks to the research he’s supporting.” Related links: One-year crew: https://www.nasa.gov/content/one-year-crew Twins Study: https://www.nasa.gov/twins-study For Kelly’s biography, visit: http://www.jsc.nasa.gov/Bios/htmlbios/kellysj.pdf Image (mentioned), Text, Credits: NASA/Tabatha Thompson/Johnson Space Center/Brandi Dean/Karen Northon.
