“A calorie isn’t just a calorie. And our mistaken faith in the power of this seemingly simple measurement may be hindering the fight against obesity.”
"Don't look at them directly,” Rie Henriksen whispers, “otherwise they get suspicious.” The neuroscientist is referring to a dozen or so chickens loitering just a few metres away in the car park of a scenic observation point for Opaekaa Falls on the island of Kauai, Hawaii. As the two try to act casual by their rented car, a jet-black hen with splashes of iridescent green feathers pecks its way along a trail of bird feed up to a device called a goal trap. Wright tugs at a string looped around his big toe and a spring-loaded net snaps over the bird. After a moment of stunned silence, the hen erupts into squawking fury. Biologists see in the feral animals an improbable experiment in evolution: what happens when chickens go wild?[more inside]

Today The Doomsday Clock will have its time recalibrated. In 2015 the scientists set the hands to 23.57 - "due to climate change, the modernization of nuclear weapons in the United States and Russia, and the problem of nuclear waste." Is the apocalypse closer or further away? Watch the result live at 13.30 EST. There's really only one way it can go.
We have identified ten red-flag areas that can help to differentiate healthy debate, problematic research practices and campaigns that masquerade as scientific inquiry. None by itself is conclusive, but a preponderance of troubling signs can help to steer the responses of scientists and their institutions to criticism.

Christian Ott, a young astrophysics professor at the California Institute of Technology, fell in love with one of his graduate students and then fired her because of his feelings, according to a recent university investigation. Twenty-one months of intimate online chats, obtained by BuzzFeed News, confirm that he confessed his actions to another female graduate student. [more inside]
For most of human history . . . [i]t was unthinkable to ignore the stars. They were critical signposts, as prominent and useful as local hills, paths or wells. The gathering-up of stars into constellations imbued with mythological meaning allowed people to remember the sky; knowledge that might save their lives one night and guide them home. Lore of the sky bound communities together. On otherwise trackless seas and deserts, the familiar stars would also serve as a valued friend. That friendship is now broken.
The whale is so big, the frogs are so bright, the Hall of Biodiversity an astonishing swarm of life. The planetarium space show tells a story, but it holds your attention by engulfing your senses with an experience. And then maybe this excitement inspires a little girl to go home and learn the names of the constellations and all the planets and their moons, and the night sky is no longer spooky darkness, but a beautiful realm full of things she can name. The museum today teaches you about science, but it makes you care by getting you to fall in love.
Dr. Henry Marsh has performed 400 "awake craniotomies" -- a surgical procedure he helped pioneer -- in which a specific kind of brain tumor that looks just like the brain itself is identified through electric stimulation and removed. Without surgery, 50 percent of patients die within 5 years; 80 percent within 10 years, and the operation can prolong their lives by 10 to 20 years or more. He was profiled in a 2007 documentary: The English Surgeon as well as this article by Karl Ove Knausgaard: The Terrible Beauty of Brain Surgery. Images in some links in this post may be disturbing to some viewers.
By the dawn of the 19th century, the deadliest killer in human history, tuberculosis, had killed one in seven of all the people who had ever lived. The disease struck America with a vengeance, ravaging communities and touching the lives of almost every family. The battle against the deadly bacteria had a profound and lasting impact on the country. It shaped medical and scientific pursuits, social habits, economic development, western expansion, and government policy. Yet both the disease and its impact are poorly understood: in the words of one writer, tuberculosis is our "forgotten plague." [54:11]

Jack Gilbert, a Microbial Ecologist at Argonne and an Assistant Professor in the Department of Ecology and Evolution at the University of Chicago, gave a free public lecture at Argonne. In recent years, scientists have discovered that our bodies teem with microbial life, which outnumber our cells 10 to one. In his talk, Gilbert explored how your microbial world influences your health, probing where that microbial world comes from, and highlighting the ways in which your lifestyle, diet and medical treatment can influence your microbiome.

Galalith. The world's first plastic. Known as "milk stone" it was created by the interaction of casein and formaline. Produced in the 1900s in great quantities in France and Germany, it was used as an ivory substitute in billiard balls, piano keys and a variety of jewelry. Production declined post-WWII and while vintage galalith is pricey on ebay you can make it yourself at home.
“Imagine a therapy that had no known side effects, was readily available, and could improve your cognitive functioning at zero cost,” the researchers wrote in their paper. It exists, they continued, and it’s called “interacting with nature.”

Breeding Improved Honey Bees was originally printed in 1951, in The American Bee Journal. It is an informative and often dryly amusing introduction to the history and arts of bee breeding. "The honey bee has a definite place in our modern world. Its products of honey and wax are useful to man, although perhaps not essential to all men." Those histories and arts are, as you might expect, covered in bees.
José L. Duarte is one author of an upcoming paper in Behavioral and Brain Sciences, "Political Diversity Will Improve Social Psychological Science." The authors review how academic psychology has lost its former political diversity, and explore the negative consequences of this on the field's search for true and valid results. Duarte has blogged about his own experience of bias when he was denied admission to a Ph.D program, possibly for for his perceived political views in another blog post. [more inside]

By comparison to what it could have been, it’s a miracle. By comparison to what it should have been, it’s a disaster. - A historic deal has been struck in Paris to reduce carbon emissions and reduce global warming, with a ceiling of 2 degrees centigrade and a goal of 1.5C. 2015 has been the hottest year on record.
One of the most beautiful, amazing, and depressing things I’ve ever done is participate in a whale necropsy. This work helps us understand the patterns of whale mortality, and determine whether whale deaths are natural, or possibly man-made. This is important stuff. In fact, their work has helped guide changes in policy, especially when it comes to designing the shipping lanes that go into and out of San Francisco Bay. Their research helped establish new, longer, and narrower shipping lanes that reduced the chances of ships hitting, and often killing, whales. This work saved whales’ lives. [more inside]

“I think the post-war turn towards social responsibility in science and engineering was less a turn than a sideways glance. .. If researchers like us were actually supposed to know or care about this stuff in any operationally significant way, well, I think we didn't get the memo. So let me retransmit it.” - Phillip Rogaway.

Last April, motivated by rumors of a Chinese paper published the next month that physically demonstrated the technical feasibility of editing human germline DNA with CRISPR by successfully modifying human embryos, a coalition of well regarded scientists assembled to address this fundamentally new ability and they called for an international summit. It was to be billed as a new Asilomar Conference on Recombinant DNA for a new age in order to lead a new global conversation on questions of whether and how to control human inheritance, which could only be dreamed of 40 years ago. This is a fundamental departure from the non-inheritable gene engineering with CRISPR covered on the blue recently. Thus, from December 1-3, the International Summit on Human Gene Editing, held as a collaborative effort between U.S. National Academy of Sciences and National Academy of Medicine, the Chinese Academy of Sciences, and The Royal Society, met to discuss the future of this technology and has come out with a clear consensus statement.

"In his final arguments to the jurors, Groenweghe called Johnson’s accusers “promiscuous.” Hands in his pockets, eyes downcast, he told the members of the jury that these young gay men “have a lifestyle I don’t understand, that many of us don’t understand. But, he said that HIV criminalization laws weren’t put on the books by legislators just to protect them, but to protect the public health — including the health of the jurors." [more inside]
Why are autumn leaves mostly yellow in Europe and red in North America? The colour of a British wood in autumn is predominantly yellow. There are relatively few European trees which have red leaves in the autumn....Autumn is much redder in North America and east Asia than it is in northern Europe, and this can’t be explained by temperature differences alone.
Sure, we may be a little weird compared to our close relatives for not having a baculum (penis bone), and maybe that's the sort of thing you want to explain for whatever reason, but does human penis size and shape need a uniquely human story? Assuming it's correlated to the vagina like it probably is in many other species, then no it doesn't... unless the size and shape of the human vagina has an exceptional story. Does it? We wouldn't know. [more inside]

When Fiona Ingleby took to Twitter last April to vent about a journal’s peer-review process, she didn’t expect much of a response. With only around 100 followers on the social-media network, Ingleby — an evolutionary geneticist at the University of Sussex near Brighton, UK — guessed that she might receive a few messages of support or commiseration from close colleagues. What she got was an overwhelming wave of reaction. Social media has enabled an increasingly public discussion about the persistent problem of sexism in science.

Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]
