A whale that lived 33 million years ago when present-day Oregon was part of the ocean floor has been newly named after a curator at the Burke Museum of Natural History and Culture in Seattle.
And Elizabeth Nesbitt’s whale isn’t your typical cetacean: An analysis of the fossil, published in the Nov. 29 issue of Current Biology, suggests that Maiabalaena nesbittae bridged a gap between species of whales that had teeth and species that have a different mouth-feeding mechanism known as baleen.
“For the first time, we can now pin down the origin of filter-feeding, which is one of the major innovations in whale history,” study co-author Nicholas Pyenson, the National Museum of Natural History’s curator of fossil marine mammals and an affiliate curator at the Burke Museum, said in a news release.
When did you first get the science bug? For me, it was my professor Tom Carlson who taught a summer class about medical ethnobotany. Seeing him chase bumblebees around the University of California, Berkeley botanical garden and describe how they fit into a foxglove flower was a life-changing experience. And this personal story is not unique—many of us can probably name a science teacher, professor, parent, or educator who got us hooked on science. That’s why education is such an important part of what we do at Science Friday. We know that’s where the spark for science often ignites.
It’s also why we team up with science educators across the country in our Science Friday Educator Collaborative Program, in which educators work with SciFri staff to develop resources for science learners everywhere. Two of this year’s Educator Collaborators, Randy Otaka and Katie Brown guide us through their creative process of designing hands-on STEM activities—from modeling camouflaging cephalopod skin with cocktail umbrellas to using design thinking to better engineer shelters for disaster relief. And if you are an educator and this sounds like something you want to do, applications are now open for the 2019 program! Science Friday’s education director Ariel Zych joins Ira to tell you how to be a part of the next cohort.
Apply for the 2019 SciFri Educator Collaborative cohort! You can click on the green notepad at the top of this page or click here to go straight to the form. We will be accepting applications until Friday, January 4th, 2019 5 PM EST.

As Mars colonization inches ever closer to becoming a reality, some have argued that the ability to afford a ticket to the Red Planet is a luxury afforded only to the wealthiest members of society. Billionaire Elon Musk has said it’ll run potential Mars inhabitants traveling with his company SpaceX hundreds of thousands of dollars to get there. But in a new interview, he rebuffed the assertion that a one-way ticket to Mars is an easy ticket out for the rich.
The comments were part of an interview with the SpaceX and Tesla CEO that will air Sunday evening in the final episode of Axios’ four-part limited documentary series on HBO. In a clip from the interview, Elon Musk hinted that advancements by his company for Mars colonization have been notable and said there’s a “70 percent” chance that he heads to the Red Planet himself.
Michael B. Fossel, M.D., Ph.D. (born 1950, Greenwich, Connecticut) was a professor of clinical medicine at Michigan State University and is the author of several books on aging, who is best known for his views on telomerase therapy as a possible treatment for cellular senescence. Fossel has appeared on many major news programs to discuss aging and has appeared regularly on National Public Radio (NPR). He is also a respected lecturer, author, and the founder and former editor-in-chief of the Journal of Anti-Aging Medicine (now known as Rejuvenation Research).
Prior to earning his M.D. at Stanford Medical School, Fossel earned a joint B.A. (cum laude) and M.A. in psychology at Wesleyan University and a Ph.D. in neurobiology at Stanford University. He is also a graduate of Phillips Exeter Academy. Prior to graduating from medical school in 1981, he was awarded a National Science Foundation fellowship and taught at Stanford University.
In addition to his position at Michigan State University, Fossel has lectured at the National Institute for Health, the Smithsonian Institution, and at various other universities and institutes in various parts of the world. Fossel served on the board of directors for the American Aging Association and was their executive director.
Fossel has written numerous articles on aging and ethics for the Journal of the American Medical Association and In Vivo, and his first book, entitled Reversing Human Aging was published in 1996. The book garnered favorable reviews from mainstream newspapers as well as Scientific American and was published in six languages. A magisterial academic textbook on by Fossel entitled Cells, Aging, and Human Disease was published in 2004 by Oxford University Press.
Since his days as a teacher at Stanford University, Fossel has studied aging from a medical and scientific perspective with a particular emphasis on premature aging syndromes such as progeria, and since at least 1996 he has been a strong and vocal advocate of [telomerase therapy]] as a potential treatment of age-related diseases, disorders, and syndromes such as progeria, Alzheimer’s disease, atherosclerosis, osteoporosis, cancer, and other conditions. However, he is careful to qualify his advocacy of telomerase therapy as being a potential treatment for these conditions rather than a “cure for old age” and a panacea for age-related medical conditions, albeit a potential treatment that could radically extend the maximum human life span and reverse the aging process in most people. Specifically, Fossel sees the potential of telomerase therapy as being the single most effective point of intervention in a wide variety of age-related medical conditions. His new book, The Telomerase Revolution, (BenBella, 2015) gives a careful explanation of aging, age-related diseases, and the prospects for intervention, including upcoming human trials.
ASHEVILLE, North Carolina — A chickenpox outbreak at a private school now ranks as North Carolina’s largest since a vaccine for the virus became available more than 20 years ago, health officials say.
The viral infection manifests in an itchy rash in most cases and is not typically life-threatening. But the outbreak at Asheville Waldorf should cause concern, said Dr. Jennifer Mullendore of Buncombe County Department of Health and Human Services.
The latest results in a long-running contest of video-game-playing AIs reveal how hard it is for machines to master swarming insectoid Zergs or blitzing Protos. They also show that even old-school approaches can still sometimes win out.
The AIIDE Starcraft Contest has been running at Memorial University in Newfoundland, Canada, since 2010. Participating teams submit bots that play an original version of Starcraft, a sprawling sci-fi-themed game, in a series of one-on-one showdowns.
Starcraftiness: Video games are generally useful in AI because they offers a constrained environment and a good way to quantify progress. The popular online strategy game Starcraft has emerged as an important benchmark for AI both because it is extremely complicated and because it’s a game where it’s hard to measure progress. There are a vast number of possible states and a huge number of potential moves at every moment. And it can be hard to tell if a strategy is a good one until much later on in a battle.
About 15 years ago, UNC Lineberger’s Dale Ramsden, Ph.D., was looking through a textbook with one of his students when they stumbled upon a scientific mystery.
A small line in the book indicated that a protein that helps repair major breaks in our genetic code did so by adding DNA, or deoxyribonucleic acid, as expected. However, there were hints that it could also add RNA, or ribonucleic acid, at least in a test tube. It seemed unlikely that this would occur during repair of DNA in living cells, since RNA is normally used only as a messenger to carry information from the genetic code to make proteins.
“You would think they must only add DNA during repair of our genetic code, because that’s the core of the central dogma of life; genetic information has to be DNA all the time,” said Ramsden, who is a professor in the UNC School of Medicine Department of Biochemistry and Biophysics. “That’s the way it’s supposed to be. That’s what we’re taught in school.”
