A microRNA plays role in major depression

by Dr. Jekyll in Lunatic Laboratories

A tiny RNA appears to play a role in producing major depression, the mental disorder that affects as many as 250 million people a year worldwide. Major depression, formally known as major depressive disorder, or MDD, brings increased risk of suicide and is reported to cause the second-most years of disability after low-back pain.

Social connectedness can increase suicide risk

by Dr. Jekyll in Lunatic Laboratories

Community characteristics play an important role in perpetuating teen suicide clusters and thwarting prevention efforts, according to a new study by sociologists who examined clusters in a single town. The study illustrates how the homogeneous culture and high degree of social connectedness of a community can increase suicide risk, particularly among teenagers.

How new experiences boost memory formation

by Dr. Jekyll in Lunatic Laboratories

Most people remember where they were when the twin towers collapsed in New York ... new research reveals why that may be the case. The study has shed new light on the biological mechanisms that drive the process, known as flashbulb memory.

CRISPR on my plate, and some GMO’s on the side

by gdw in FictionalFieldwork

A CRISPR recipe Less than a month ago, the world’s first official CRISPR/Cas9 meal was served. CRISPR/Cas9 is a fairly new technology to edit genomes, and cut and paste genes at will. Well, it’s not exactly that new. It’s actually been around for a long time. CRISPR, or *humhum* Clustered regularly interspaced short palindromic repeats […]... Read more »

Antimicrobial chemicals found with antibiotic-resistance genes in indoor dust

by Dr. Jekyll in Lunatic Laboratories

Researchers have found links between the levels of antimicrobial chemicals and antibiotic-resistance genes in the dust of an aging building used for athletics and academics. One of the antimicrobials seen in the study is triclosan, a commonly used antibacterial ingredient in many personal care products.

Drugs in the water? Don't blame the students

by Dr. Jekyll in Lunatic Laboratories

With nearly sixty percent of American adults now taking prescription medications--from antidepressants to cholesterol treatments--there is growing concern about how many drugs are flowing through wastewater treatment facilities and into rivers and lakes. Research confirms that pharmaceutical pollution can cause damage to fish and other ecological problems--and may pose risks to human health too.

Babies chew on subtle social, cultural cues at mealtime

by Dr. Jekyll in Lunatic Laboratories

At the dinner table, babies do a lot more than play with their sippy cups, new research suggests. Babies pay close attention to what food is being eaten around them - and especially who is eating it. The study adds evidence to a growing body of research suggesting even very young children think in sophisticated ways about subtle social cues.

Scientists show that a 'Superman' disguise could actually work

by Dr. Jekyll in Lunatic Laboratories

Ever think it's silly that people don't recognize Clark Kent is actually Superman? Well as it turns out, glasses are actually a fairly good way to disguise yourself. In fact, researchers have shown that small alterations to a person's appearance, such as wearing glasses, can significantly hinder positive facial identification.

Use it or lose it: Stopping exercise decreases brain blood flow

by Dr. Jekyll in Lunatic Laboratories

We all know that we can quickly lose cardiovascular endurance if we stop exercising for a few weeks, but what impact does the cessation of exercise have on our brains? New research examined cerebral blood flow in healthy, physically fit older adults (ages 50-80 years) before and after a 10-day period during which they stopped all exercise.

A visual nudge can disrupt recall of what things look like

by Dr. Jekyll in Lunatic Laboratories

Interfering with your vision makes it harder to describe what you know about the appearance of even common objects, according to researchers. This connection between visual knowledge and visual perception challenges widely held theories that visual information about the world -- that alligators are green and have long tails, for example -- is stored abstractly, as a list of facts, divorced from the visual experience of seeing an alligator....

The relationship between low physical activity and psychotic symptoms

by Dr. Jekyll in Lunatic Laboratories

Physical activity can help reduce cardiovascular disease and premature mortality in people with psychological problems. However, there is limited data on exercise in people with serious mental disorders, especially from low- and middle-income countries. This study explored whether complying with the World Health Organization recommendations of 150 minutes of moderate-vigorous exercise per week is related to psychotic symptoms or the diagnosis of a psychosis.

Too much activity in certain areas of the brain is bad for memory and attention

by Dr. Jekyll in Lunatic Laboratories

Neurons in the brain interact by sending each other chemical messages, so-called neurotransmitters. Gamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter, which is important to restrain neural activity, preventing neurons from getting too trigger-happy and from firing too much or responding to irrelevant stimuli.

Stroke-like brain damage is reduced in mice injected with omega-3s

by Dr. Jekyll in Lunatic Laboratories

A stroke can happen at any age, and as with anything that involves the brain, a few seconds can be life altering. Usually the rule is time lost is brain lost, but there might be some good news regarding that, researchers found that omega-3 fatty acids reduced brain damage in a neonatal mouse model of stroke.

In cells, some oxidants are needed

by Dr. Jekyll in Lunatic Laboratories

Within our bodies, high levels of reactive forms of oxygen can damage proteins and contribute to diabetic complications and many other diseases. But some studies are showing that these reactive oxygen species (ROS) molecules sometimes can aid in maintaining health--findings now boosted by a surprising discovery by researchers.

Are Teaching and Learning Coevolved?

by Joshua Fisher in Text Savvy

Post moved to http://guzintamath.com/blog/2016/08/teaching-learning-coevolved/

Strauss, Ziv, and Stein (2002) . . . point to the fact that the ability to teach arises spontaneously at an early age without any apparent instruction and that it is common to all human cultures as evidence that it is an innate ability. Essentially, they suggest that despite its complexity, teaching is a natural cognition that evolved alongside our ability to learn.... Read more »

How do researchers and journalists in Brazil relate to each other?

by SciELO in SciELO in Perspective

Scientists admit that dealing with complex issues related to their research with journalists is not an easy task. However, long they realized that communicate their results in scientific journals is not enough. To obtain research grants, attract collaboration opportunities and for career advancement, it is necessary - and advisable - to communicate with the public through journalists. Read about the details of this relationship and what can be done to improve it. … Read More →... Read more »

Science Without Open Data Isn't Science

by Neuroskeptic in Neuroskeptic_Discover

A new position paper published in the New England Journal of Medicine (NEJM) has generated a lot of controversy among some scientists: Toward Fairness in Data Sharing.

It's not hard to see why: the piece criticizes the concept of data sharing in the context of clinical trials. Data sharing is the much-discussed idea that researchers should make their raw data available to anyone who wants to access it. While the NEJM piece is specifically framed as a rebuttal to this recent pro-data sharing N... Read more »
