Artificial DNA Base Pair Expands Life’s Vocabulary

Scientists have taken another step towards putting two additional letters in the dictionary of life to work. Researchers at the Scripps Institute have engineered cells to successfully transcribe a brand new artificial DNA base pair and make a never-before-seen protein with it. The breakthrough is part of an effort to expand the library of amino acids that animal cells can work with, potentially leading to the creation of compounds entirely different from those life can produce now. The

Smile, Your Car Is on Google Street View

When sedans outnumber pickup trucks, chances are the community votes Democrat. When pickup trucks rule, the community leans Republican. What you drive matters, at least when it comes to revealing the nuts and bolts of American demographics. That’s the assertion by researchers in a paper published in November in the journal the Proceedings of the National Academy of Sciences. For thousands of years, authorities have conducted surveys to determine the demographic of regions and cities. I

Heart-Stopping Sex? Forget About It

During sex, the heart races, blood pressure rises and the breath quickens, sometimes to a pant. Muscles tense and euphoric feelings flood the brain. This is not a time to be thinking, “I hope my heart doesn’t stop.” But according to cardiologists, male patients over 50 during checkups sometimes ask what the chance is of a heart attack or sudden cardiac arrest during sexual intercourse. The concern is based on the heightened physiology experienced (racing heart, contracted muscles, etc.

Why Some Bird Babies Ride Piggyback

Having your children trail you like ducklings in a pond sounds pretty good to human parents, who are stuck carrying or pushing their offspring through toddlerhood. But some animals with mobile babies choose to carry them anyway. One scientist looked at waterbirds to figure out why certain species find it worthwhile to haul their kids around, while others leave them to paddle alone. The reasons he found range from snuggle time to murderous fish. Animals including anteaters, bats, prima

The Bottom of the Barrel of Science Fraud

Sometimes, scientific misconduct is so blatant as to be comical. I recently came across an example of this on Twitter. The following is an image from a paper published in the Journal of Materials Chemistry C: As pointed out on PubPeer, this image - which is supposed to be an electron microscope image of some carbon dot (CD) nanoparticles - is an obvious fake. The "dots" are identical, and have clearly been cut-and-pasted. Where one copy has been placed over the top of another, the overlap
