3-billion-year-old zircon crystals point to a "Lost continent" found under Mauritius. Lava-covered piece of continent is an ancient remnant, left over from the break-up of the supercontinent, Gondwana, which started about 200 million years ago.


Doctors have used a brain-reading device to hold simple conversations with “locked-in” patients in work that promises to transform the lives of people who are too disabled to communicate.


Scientists identify earliest protein necessary for cell division. The protein sas-7, pulled from roundworms, is now considered the earliest known actor in the early cell division that is vital to the molecular machinery that directs the genetic traffic that builds all animals.


Ancient proteins dating back 195 million years have been found inside a dinosaur bone pushing back the oldest evidence for preserved proteins by 100 million years.


Restoring native plants 'boosts pollination'. Removing invasive exotic plants from natural areas can act as a boost for wildlife, a study suggests. Bees, butterflies and birds returned to remote mountaintops in the Seychelles only six months after exotic plants were removed.


For 4 years straight a medical researcher was on call 24/7 anytime lung surgery happened in her city so she could receive samples of fresh tissue. Her work discovered stem cells that make mistakes in repairing DNA as a likely culprit of a major lung cancer.


Scientists have analysed accounts from people who have had near death experiences and identified “life review experience” (LRE) as a trend. LRE may occur because certain parts of the brain that stores memories are among the last to shut down when the body is close to death.


Do you have a college degree or higher in science? Get flair indicating your expertise in /r/science!

Science Verified User Program

/r/science has a a system of verifying accounts for commenting, enabling trained scientists, doctors and engineers to make credible comments in /r/science . The intent of this program is to enable the general public to distinguish between an educated opinion and a random comment without a background related to the topic.

What flair is available?

All of the standard science disciplines would be represented, matching those in the sidebar. However, to better inform the public, the level of education is displayed in the flair too. For example, a Professor of Biology is tagged as such (Professor | Biology), while a graduate student of biology is tagged as "Grad Student | Biology." Nurses would be tagged differently than doctors, etc...

We give flair for engineering, social sciences, natural sciences and even, on occasion, music. It's your flair, if you finished a degree in something and you can offer some proof, we'll consider it.

The general format is:

Level of education|Field|Speciality or Subfield (optional)

When applying for a flair, please inform us on what you want it to say.

How does one obtain flair?

First, have a college degree or higher.

Next, send an email with your information to redditscienceflair@gmail.com with information that establishes your claim, this can be a photo of your diploma or course registration, a business card, a verifiable email address, or some other identification.

Please include the following information:

Username: Flair text: Degree level | Degree area | Speciality Flair class:

for example:

Username: nate

Flair text: PhD | Chemistry | Synthetic Organic

Flair Class: chemistry

Due to limitations of time (mods are volunteers) it may take a few days for you flair to be assigned, (we're working on it!)

This email address is restricted access, and only mods which actively assign user flair may log in. All information will be kept in confidence and not released to the public under any circumstances. Your email will then be deleted after verification, leaving no record. For added security, you may submit an imgur link and then delete it after verification.

Remember, that within the proof, you must tie your account name to the information in the picture.

What is expected of a verified account?

We expect a higher level of conduct than a non-verified account, if another user makes inappropriate comments they should report them to the mods who will take appropriate action.

Thanks for making /r/science a better place!

Science AMA Series: We’re David Pogue, tech guru and host of 16 NOVA programs, and Chris Schmidt, NOVA senior producer. Today, we launched NOVA’s first crowdfunding campaign, because we think involving people in science is important. Ask us anything!


See the source article by following the link below:

Hi, everyone! I’m David Pogue—former New York Times tech columnist, current Yahoo tech critic, and—most importantly for today’s conversation—the host of 16 NOVA programs that have aired on PBS! Some of those include the MAKING STUFF and MAKING STUFF 2 series, and the two-hour HUNTING THE ELEMENTS movie: a crash course on The Periodic Table that over 10 million people have watched so far.

Today, we’re embarking on a Kickstarter journey—not only to make a sequel to HUNTING THE ELEMENTS, called BEYOND THE ELEMENTS, but to gain a deeper connection with NOVA’s audience. We think that more engaging science programming can be a key to generating public excitement for science and scientific discovery.

I’ve also got Chris Schmidt with me. He’s a Senior Producer at NOVA, with decades of award-winning science television under his belt. (Chris’s IMDB page) He’s done a ton of stuff at PBS, Dreamworks Animation, The Discovery Channel, History Channel, National Geographic, Animal Planet, and others. He’ll be producing and directing BEYOND THE ELEMENTS.

Together, we’ve had some wild adventures making documentaries that attempt to engage all levels of science lovers. We’re here to talk about making science television, the importance of science literacy, and the role that media plays in educating the public about science. And about how we think the audience should be part of it all! Ask us anything!

Watch our latest doc, SEARCH FOR THE SUPER BATTERY, tomorrow, February 1, at 9/8c on most PBS stations. (Check your local listings to confirm.)

500-million year-old species offers insights into the lives of ancient legged worms


Researchers have theoretically shown that microbes could influence their hosts to act altruistically. This influence could be surprisingly effective, with simulations showing that microbes may promote the evolution of altruistic behavior in a population to a greater extent than genetic factors do.

American Chemical Society AMA: I am Allison Campbell, President of the American Chemical Society. Ask me anything about the importance of sharing science and my priorities for ACS!


See the source article by following the link below:

Hi Reddit! I’m Allison Campbell, President of the American Chemical Society. Currently I am the Associate Laboratory Director of the Earth and Biological Sciences Directorate at Pacific Northwest National Laboratory (PNNL). A physical chemist by academic training, my research has focused on biomaterials.

My research focus is on the role of proteins in biomineralization. During my time in the Materials Science Department at PNNL, I have co-invented a process inspired by biology that allows us to grow bioactive calcium phosphate layers onto the surfaces of artificial joint implants. By mimicking bone, this innovation can extend the life of the implant and reduce implant rejection. I hold a PhD in physical chemistry from the State University of New York at Buffalo, and a BA from Gettysburg College in Gettysburg, PA. I have been a member of the ACS since 1985 and in that time have become a member of the National Academy of Sciences Chemical Sciences Roundtable and was named an AAAS Fellow in 2013.

One aspect of science I’m most passionate about is promoting science education and sharing scientific information. As often as I can, I share my personal enthusiasm for science with young students and participate in a number of hands-on education programs. As ACS President I feel it’s so important that all us chemists out there should share with the public what chemistry is and how it helps society. This means we need to get as good at science communication as we can. I also feel it is greatly important to foster common principles and practices among the global chemistry community. You can read about these and my priorities as ACS President in my Chemical & Engineering News statement “Pedaling the power of chemistry.”

Ask me anything about my ACS priorities of sharing the value of chemistry and building its global principles and practices. You can also ask about my research in biomineralization.

Note that as a scientist employed by a federal laboratory, I am bound by the Hatch Act and therefore may not engage in questions of a political nature.

I will be back at 11am EST (8am PST, 4pm UTC) to start answering questions.
