8:44 PM | Is That A Real Patient Or A Junkie? Now There's An App For That
A middle aged, male, investment banker arrives at the emergency department with complaints of nausea, vomiting, anxiety and tremor. At business lunches and then at home every evening, he was drinking too much so, worried about his health, he decided to quit drinking and had his last Scotch 24 hours before coming to the emergency room. It's a common scenario in emergency rooms - a patient suddenly stops regular, excessive alcohol consumption and develops withdrawal symptoms.read more

8:00 PM | All Living Creatures Need Vitamin Thiamine To Live - Except This One
Some species of marine phytoplankton, such as the prolific bloomer Emiliania huxleyi, can grow without consuming vitamin B1 (thiamine), which contradicts the common view that E. huxleyi and many other eukaryotic microbes depend on scarce supplies of thiamine in the ocean to survive. All living creatures need thiamine to live, as well as other vitamins. Organisms may produce some of their own vitamins, the way that human cells create vitamin D with help from sunlight, but sometimes they rely on […]

7:45 PM | Russian Army Wives Demand Answers About Their Incognito Husbands
Yesterday, the U.S. State Department confirmed that over 1,000 Russian troops and armored vehicles had crossed the border into Ukraine and engaged in the fighting there. Despite satellite imagery released by NATO showing the Russian forces, Russian President Vladimir Putin is still denying that the troops and weaponry are of Russian origin. Now, even people within Russia want some answers. Yesterday, several dozen mothers and wives gathered outside of a Russian military base […]

7:30 PM | Nitrogen-Transforming Bacteria: Now Powered By Hydrogen
Nitrite-oxidizing bacteria are key players in the natural nitrogen cycle on Earth and in biological wastewater treatment plants but scientists have learned something new about how they are powered.  For decades, these specialist bacteria were thought to depend on nitrite as their source of energy researchers have now shown that nitrite-oxidizing bacteria can use hydrogen as an alternative source of energy. The oxidation of hydrogen with oxygen enables their growth independent of nitrite […]

7:15 PM | Chemical Signals: Sexual Attraction, Pheromones And Being Ready At The Right Time
The exchange of chemical signals between organisms is considered the oldest form of communication. Acting as messenger molecules, pheromones regulate social interactions between conspecifics, for example, the sexual attraction between males and females. Fish rely on pheromones to trigger social responses and to coordinate reproductive behavior in males and females. read more

6:00 PM | Snail's Tales: The Rise And Fall Of The Tibetan Plateau
The rise of the Tibetan plateau, the largest topographic anomaly above sea level on Earth, is important for both its profound effect on climate and its reflection of continental dynamics. For a new study, Katharine Huntington and colleagues employed a cutting-edge geochemical tool - "clumped" isotope thermometry - using modern and fossil snail shells to investigate the uplift history of the Zhada basin in southwestern Tibet. read more

5:31 PM | Proton-Proton Fusion: Looking Into The Heart Of The Sun
Using the Borexino instrument, located deep beneath Italy's Apennine Mountains and one of the most sensitive neutrino detectors on the planet, an international team of physicists has directly detected neutrinos created by the "keystone" proton-proton (pp) fusion process going on at the sun's core.  The pp reaction is the first step of a reaction sequence responsible for about 99 percent of the Sun's power. Solar neutrinos are produced in nuclear processes and radioactive decays of […]

5:07 PM | Why Replacing Teachers With Automated Education Lacks Imagination
By George Veletsianos, Royal Roads UniversityThe belief that technology can automate education and replace teachers is pervasive. Framed in calls for greater efficiency, this belief is present in today’s educational innovations, reform endeavors, and technology products. We can do better than adopting this insipid perspective and aspire instead for a better future where innovations imagine creative new ways to organize education. read more

What ancient stories do fossil meteorites hold? Find out in this new video from The Brain Scoop, featuring some exceedingly rare extraterrestrial rocks and a very expensive science machine. Until today I never knew that meteorites could fossilize. I knew that they could be mistaken for loaves of bread by Russian farmers and eaten, diamonds and all, but fossilized? That’s news to me. Thanks Emily!

4:57 PM | India’s RICE Bucket Challenge Just Totally Nailed It
The ALS ice bucket challenge has become a global phenomenon this summer, with people dumping buckets full of water and ice on their heads to raise awareness and funding for ALS. Now, India has adopted the challenge, adding their own spin: instead of filling the buckets with ice and water, they fill them with rice. And instead of dumping the bucket over their heads, they give the bucket of rice to a person in need. The new challenge was started by

4:44 PM | Caterpillar Madness
During monsoon season in Southern Arizona, the desert is teeming with life. Just this morning, on my way in from feeding the horses, I saw my horned lizard friend and a praying mantis. Horned lizard young hatch during this time of year, so I'll be watching for these miniature desert tanks. Earlier in the season, a fantastic event occurred, one I hadn’t observed before. I wasn’t quick enough with my camera, and thought I’d lost the opportunity to film the... Read more

4:03 PM | Interview with Maryam Mirzakhani, the brilliant Iranian mathematician who was the first woman to win the Fields Medal
Interviewer: What advice would you give lay persons who would like to know more about mathematics—what it is, what its role in our society has been and so on? What should they read? How should they proceed? Dr. Mirzakhani: This is a difficult question. I don’t think that everyone should become a mathematician, but I do believe that many students don’t give mathematics a real chance. I did poorly in math for a couple of years in middle school; I was just not […]

3:27 PM | Making People Laugh About Science. It’s a Good Thing.
Why was Schrödinger afraid of his cat? Because it was both dead and alive at the same time!  Alright, so admittedly I’m no quantum theory comedian. But if you brushed up on your science communication strategies recently, attended a talk at a local science museum or read a Brain Flapping post by Dean Burnett at The Guardian, you might have noticed that science comedy is a hot thing. And for good reason. It turns out that using humour and even... Read more

2:48 PM | Studying Prefrontal Lobe Damage Unlocks Brain Mysteries
Until the last few decades, the frontal lobes of the brain were shrouded in mystery and erroneously thought of as nonessential for normal function—hence the frequent use of lobotomies in the early 20th century to treat psychiatric disorders. A review in Neuron highlights studies of patients with brain damage that reveal how distinct areas of the frontal lobes are critical for a person's ability to learn, multitask, control their emotions, socialize, and make real-life […]

2:14 PM | 3 Papers Discuss The Molecular Toolkits We Share With Flies And Worms
Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression and it's all in our genomic data. Three related studies in Nature, tell a similar story: even though humans, worms, and flies bear little obvious similarity to each other, evolution used remarkably similar molecular toolkits to shape them. There are dramatic differences between species in genomic regions populated by pseudogenes, molecular fossils of working […]

2:05 PM | Learning New Skills: It's All About Flexing The Brain
Learning a new skill is easier when it is related to an ability we already have. For example, a trained pianist can learn a new melody easier than learning how to hit a tennis serve. Scientists from the Center for the Neural Basis of Cognition (CNBC) have discovered a fundamental constraint in the brain that may explain why this happens. Writing in Nature, they say that there are limitations on how adaptable the brain is during learning and that these restrictions are a key determinant for […]

Media for Thinking the Unthinkable Today’s pick is a scannable collection of software demonstration videos, all designed as prototypes of “a new medium for science and engineering” that amplifies/extends intuition and the senses as much as analytical thinking. Demos start with a redesign of the traditional scientific journal article and head down the rabbit hole from there. Exploring natural systems and communicating discoveries about them (i.e., doing science) is a creative […]

1:26 PM | Breaking research: A study in fruit flies finds a possible drug target to compensate for symptoms of Parkinson’s disease
Parkinson’s disease is caused by the progressive death of neurons important for movement and results in symptoms such as shaking or rigidity in the limbs, slow movements, and difficulty walking. The primary treatment is a drug called L-Dopa, which compensates for the neuron loss but eventually becomes less effective as more and more neurons die […]
