Bacteria in branches naturally fertilize trees

by Dr. Jekyll in Lunatic Laboratories

The bacteria in and on our bodies have been shown to be vital for human health, influencing nutrition, obesity and protection from diseases. But science has only recently delved into the importance of the microbiome of plants. Since plants can't move, they are especially reliant on partnerships with microbes to help them get nutrients.

You are what you eat: Immune cells remember their first meal

by Dr. Jekyll in Lunatic Laboratories

Scientists have identified the trigger for immune cells' inflammatory response -- a discovery that may pave the way for new treatments for many human diseases. Immune cells play essential roles in the maintenance and repair of our bodies. When we injure ourselves, immune cells mount a rapid inflammatory response to protect us against infection and help heal the damaged tissue.

Your friends have more friends than you do

by Dr. Jekyll in Lunatic Laboratories

No matter how smart and funny you think you are, those you follow on Twitter really do have a larger following than you. And the same holds true for Facebook. But there is no reason to feel badly about any of this. According to the research, it is all due to the inherently hierarchical nature of social media networks, where, in the social hierarchy of connections, people mostly either follow up or across; they rarely follow down.

Converting cells to burn fat, not store it

by Dr. Jekyll in Lunatic Laboratories

Researchers have uncovered a new molecular pathway for stimulating the body to burn fat -- a discovery that could help fight obesity and cardiovascular disease.By focusing on a protein known as folliculin, and knocking out the gene that produces it in fat cells, the researchers triggered a series of biomolecular signals that switched the cells from storing fat to burning it.

Academic publication quality and the senility of science

by gdw in FictionalFieldwork

A recent column in Nature by Daniel Sarewitz laments the ever increasing torrent of academic publications. Quantity goes up, but quality does not follow suit. There are more scientists than ever. And they publish more than ever. However, that doesn’t mean they publish more high quality research. This harks back to the work of Derek J. […]... Read more »

Brain cells that aid appetite control identified

by Dr. Jekyll in Lunatic Laboratories

It's rare for scientists to get what they describe as "clean" results without spending a lot of time repeating the same experiment over and over again. But when researchers saw the mice they were working with doubling their weight within a month or two, they knew they were on to something.

Bacteria are individualists

by Dr. Jekyll in Lunatic Laboratories

No two bacteria are identical - even when they are genetically the same. A new study from researchers reveals the conditions under which bacteria become individualists and how they help their group grow when times get tough. Whether you are a human or a bacterium, your environment determines how you can develop.

Neuroscientists discover new learning rule for pattern completion

by Dr. Jekyll in Lunatic Laboratories

Recently, scientists discovered a new learning rule for a specific type of excitatory synaptic connection in the hippocampus. These synapses are located in the so-called CA3 region of the hippocampus, which plays a critical role for storage and recall of spatial information in the brain. One of its hallmark properties is that memory recall can even be triggered by incomplete cues. This enables the network to complete neuronal activity patterns, a phenomenon termed pattern completion.

Could flies help us understand brain injuries?

by Dr. Jekyll in Lunatic Laboratories

Each year, an estimated 1.7 million people in the United States sustain traumatic brain injuries (TBIs), according to the U.S. Centers for Disease Control and Prevention. These injuries occur most frequently from falling, but can also result from military combat, car accidents, contact sports or domestic abuse. Recently, physicians and researchers have become increasingly concerned that even mild cases of repetitive brain trauma could have long-term, unanticipated consequences.

Research shows body image linked to overall life satisfaction

by Dr. Jekyll in Lunatic Laboratories

We're constantly bombarded by advertisements telling us we are too fat, too thin, not curvy enough, not flat enough -- or more often than not -- simply not enough. It shouldn't be a surprise to see that effect our day to day life, like it or not -- and it has. Researchers have just published results from a national study on the factors linked to satisfaction with appearance and weight.

The adoption of English among SciELO Brazil journals has been increasing

by SciELO in SciELO in Perspective

The adoption of the English language is one of the advances that SciELO is promoting in order to increase the insertion, visibility and international impact of journals and the research they communicate. In recent years, the adoption of English has growing consistently among SciELO journals, which, from 2014 reached the milestone of publishing more in English than in Portuguese. The expectation of SciELO is that in the 2 to 3 forthcoming years 75% of the articles will be published in English and........ Read more »

Epigenetic study of lactose intolerance may shed light on the origin of mental illness

by Dr. Jekyll in Lunatic Laboratories

A new study on the epigenetics of lactose intolerance may provide an approach to understanding schizophrenia and other complex, serious illnesses. While that may seem odd, both lactose intolerance and schizophrenia are inherited. In addition, neither condition emerges in the first years of life, but rather both appear years or even decades later.

The Princess IS the Frog (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Hayley TrzinskiImage by Hayley TrzinskiThe Princess and the Frog is a very fun and imaginative children’s story… but not when pesticides are involved. Have you ever wondered how dangerous pesticides can be? Well, pesticides can harm more than just pests and weeds, and in the case of frogs, many pesticides and herbicides are causing problems. Atrazine, a chemical commonly used as an herbicide, can cause reproduction in male African clawed frogs to be impossible. In some cases, atrazine i........ Read more »

Smartphones uncover how the world sleeps

by Dr. Jekyll in Lunatic Laboratories

A pioneering study of worldwide sleep patterns combines math modeling, mobile apps and big data to parse the roles society and biology each play in setting sleep schedules. The study used a free smartphone app that reduces jetlag to gather robust sleep data from thousands of people in 100 nations. The researchers examined how age, gender, amount of light and home country affect the amount of shut-eye people around the globe get, when they go to bed, and when they wake up.

Origin of synaptic pruning process linked to learning, autism and schizophrenia identified

by Dr. Jekyll in Lunatic Laboratories

Vaccines don't cause autism, but because the brain is so complex, we still don't know how much of it works so figuring out the real causes (as in more than one) of autism has been slow going. Well, researchers have identified a brain receptor that appears to initiate adolescent synaptic pruning, a process believed necessary for learning, but in this case it is one that appears to go awry in both autism and schizophrenia....

Influence of religion and predestination on evolution and scientific thinking

by Dr. Jekyll in Lunatic Laboratories

Generally seen as antithetical to one another, evolution and religion can hardly fit in a scientific discourse simultaneously. However, in a new article, a biology researcher delves into observations on the influences a few major religions have had on evolutionists and their scientific thinking over the centuries.

Being Explicit About Symmetry

by Joshua Fisher in Text Savvy

Post moved: http://guzintamath.com/blog/2016/05/explicit-symmetry/

Working to orient oneself to the symmetries available in mathematical situations seems like one appropriate remedy to what I've called "left-to-rightism," or "cinemathematics"—a syndrome that makes us teach concepts like the equals sign (unwittingly) in a left-to-right way, such that students take away (unwittingly) the misconception that the equals sign indicates that some answer is to follow, rather than that two expressio........
