The red berries of the Brazilian peppertree—a weedy, invasive species
common in Florida—contain an extract with the power to disarm
dangerous antibiotic-resistant staph bacteria, scientists at
Emory University have discovered.
The journal Scientific Reports is publishing the finding, made in the
 lab of Cassandra Quave, an assistant professor in
Emory's Center for the Study of Human Health and in the
School of Medicine's Department of Dermatology.

Evernote nas nuvens

Em setembro, anunciamos que a Evernote migraria para uma moderna infraestrutura na nuvem e não perdemos tempo para iniciar esse processo.
Apenas um mês após o anúncio, já estávamos movendo dados para a Google Cloud Platform. Agora já podemos dizer que migramos com sucesso nosso serviço para a nuvem, e conseguimos isso com impacto mínimo para nossos clientes./.../
* PS: Há aproximadamente 150 milhões de livros publicados na história do mundo moderno. Cada livro ocuparia 2 MB de espaço no computador para ser armazenado. Todos os livros publicados no mundo moderno = 300 milhões MB = 0,3 PB. Movemos 3 PB. Isso é equivalente a mover aproximadamente 10x o número de livros que já foram publicados na história moderna.

Healthy diet

Why you should eat 10 portions of fruit or vegetables a day
February 24, 2017

image credit | iStock Eating 800 grams a day (about ten portions*) of fruit or vegetables could reduce your chance of heart attack, stroke, cancer, and early death, scientists from Imperial College London conclude from a meta-analysis of 95 studies on fruit and vegetable intake. The study, published in an open-access paper in the International Journal of Epidemiology, included … more…

An ultra-low-power artificial synapse for neural-network computing

Brain-like device with 500 states instead of binary could one day communicate with live neurons, merging computers with the brain
February 24, 2017

(Left) Illustration of a synapse in the brain connecting two neurons. (Right) Schematic of artificial synapse (ENODe), which functions as a transistor. It consists of two thin, flexible polymer films (black) with source, drain, and gate terminals, connected by an electrolyte of salty water that permits ions to cross. A voltage pulse applied to the “presynaptic” layer (top) alters the level of oxidation in the “postsynaptic layer” (bottom), triggering current flow between source and drain. (credit: Thomas Splettstoesser/CC and Yoeri van de Burgt et al./Nature Materials)
Stanford University and Sandia National Laboratories researchers have developed an organic artificial synapse based on a new memristor (resistive memory device) design that mimics the way synapses in the brain learn. The new artificial synapse could lead to computers that better recreate the way the human brain processes information. It could also one day directly interface with the human brain./.../

Mind-gut connections

Quick and Dirty TipsWELLNESS
Is Your Gut Making You Depressed or Anxious?
This week Savvy Psychologist Dr. Ellen Hendriksen goes straight for the gut with three surprising mind-gut connectionsBy Savvy Psychologist Ellen Hendriksen on February 11, 2017
Credit: Jens Magnusson Getty Images
If you had to guess the organ that has undue influence on your emotions, your mood, even your choices, what would you guess? The brain? Sure, but what else? The heart—that mythological seat of the soul? Not quite. The stomach? You’re getting warmer. Would you believe it’s the large and small intestine, collectively known as the gut? More specifically, it’s the trillions of bacteria—the microbiota—that live in your gut. Each of us carries up to four and a half pounds of bacteria around in our guts at any given time. More than 100 trillion microbes live down there. That’s as many cells as make up the rest of your body.
Now, this crowd is mostly good guys, and they do important work, to the extent that some scientists advocate classifying these collective microbiota as its own organ. Aside from helping digest our food, they protect us from disease, neutralize some of the toxic by-products of the digestive process, and make it harder for bad bacteria to set up shop. In short, your gut does way more than just digest everything from Cheetos to camembert.
But it turns out gut bacteria may also affect how we feel. Who knew the next frontier in mental well-being would lead right to the toilet? With that lovely image in mind, here are 3 big ways our microbiota are connected to our mental health.

Interests in Context As a boy, Oliver Sacks loved chemistry. Though later known as a neurologist, Dr. Sacks was captivated by a different science as a child. In his book *Uncle Tungsten*, he reflects on his “chemical boyhood”: his early passion for understanding the world and its history in chemical terms. Dr. Sacks, born in London in 1933, describes his enchantment in learning not only contemporary chemistry, but also its history. By the time he was delving into chemical handbooks, just after the second World War, much of the information in his shabby, older volumes, and many of the... mais »

The Function of Reason *A Conversation With Dan Sperber* *Contrary to the standard view of reason as a capacity that enhances the individual in his or her cognitive capacities—the standard image is of Rodin’s "Thinker," thinking on his own and discovering new ideas—what we say now is that the basic functions of reason are social. They have to do with the fact that we interact with each other’s bodies and with each other’s minds. And to interact with other’s minds is to be able to represent a representation that others have, and to have them represent our representations, and also... mais »
