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.

Theses and dissertations: pros and cons of the traditional and alternative formats

by SciELO in SciELO in Perspective

In order to expedite the writing and assessment of theses, institutions and graduate programs in several countries, including Brazil, are choosing to allow candidates who have published papers on their masters or doctorate research topics to replace the thesis chapters by these articles, headed by an introduction, conclusion and review of scientific literature. Is this format ideal and applicable to all? … Read More →... Read more »

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 »

Discovering a glaring error in a research paper – a personal account

by Richard Kunert in Brain's Idea

New York Magazine has published a great article about how grad student Steven Ludeke tried to correct mistakes in the research of Pete Hatemi and Brad Verhulst. Overall, Ludeke summarises his experience as ‘not recommendable’. Back in my undergraduate years I spotted an error in an article by David DeMatteo and did little to correct it. […]... Read more »

Why you're stiff in the morning: Your body suppresses inflammation when you sleep at night

by Dr. Jekyll in Lunatic Laboratories

Feeling stiff first thing in the morning? It's not your imagination, new research has found a protein created by the body's "biological clock" that actively represses inflammatory pathways within the affected limbs during the night. This protein, called CRYPTOCHROME, has proven anti-inflammatory effects in cultured cells and presents new opportunities for the development of drugs that may be used to treat inflammatory diseases and conditions, such as arthritis.

From Sci Fi to reality: Unlocking the secret to growing new limbs

by Dr. Jekyll in Lunatic Laboratories

Many lower organisms retain the miraculous ability to regenerate form and function of almost any tissue after injury. Humans share many of our genes with these organisms, but our capacity for regeneration is limited. So scientists are studying the genetics of these organisms to find out how regenerative mechanisms might be activated in humans.

Instructions to authors of Health Science journals: what do they communicate?

by SciELO in SciELO in Perspective

Instructions to authors (IA) allegedly contain all necessary and sufficient information to guide authors on the correct submission of a manuscript to a journal.

eBooks – global market and trends – Part III – Final: The publication of printed and digital books in the global context

by SciELO in SciELO in Perspective

The e-book Global report shows that the traditional model based on large publishing houses was insufficient to incorporate the possibilities of technological advances. On the one hand, the new reading models through smartphones and subscription platforms and on the other hand, self-publishing of ebooks open opportunities to both individual authors and non-profit organizations in the educational field to produce and distribute their own works at low cost and minimal infrastructure requirements. &........
