The use of research metrics is diversified in the Leiden Manifesto

by SciELO in SciELO in Perspective

Research evaluation in recent decades has been increasingly conducted through metrics and indicators, which are gradually replacing the assessment by peers. Researchers gathered at the 19th International Conference on Science and Technology Indicators (STI 2014) held in September 2014 in Leiden, Netherlands, in order to advise on the use of metrics in research assessment drafted a set of rules - the Leiden Manifesto. Know its guidelines. … Read More →... Read more »

Pesticides alter bees’ brains, making them unable to live and reproduce adequately

by Dr. Jekyll in Lunatic Laboratories

A new report suggests that a particular class of pesticides called “neonicotinoids” wreaks havoc on the bee populations, ultimately putting some crops that rely on pollination in jeopardy. Specifically, these pesticides kill bee brain cells, rendering them unable to learn, gather food and reproduce. The report, however, also suggests that the effects of these pesticides on bee colonies may be reversible by decreasing or eliminating the use of these pesticides on plants pollinated by bees and........

Bupropion: A Non-stimulant ADHD Drug Treatment

by William Yates, M.D. in Brain Posts

Stimulant drugs including dextroamphetamine (Adderall) and methylphenidate (Ritalin) remain among the most common and effective drug treatments for attention deficit hyperactivity disorder (ADHD).Alternative to stimulant drugs are needed to expand treatment options for clinicians and patients.One problem with the stimulants is the potential for misuse and diversion of prescription drugs to illicit drug use.One non-stimulant FDA approved drug (atomoxetine/Strattera) is available in the U.S.An add........

Why the message – that we're all prone to stereotyping others – is so dangerous

by BPS Research Digest in BPS Research Digest

Telling people they are biased in their treatment of others – that they are racist or ageist, for example – can make them defensive and result in backlash. For this reason, change-makers nowadays often spread a different message: that stereotyping others isn’t a personal sin, but near-universal and something we must all aim to resist. However a new paper from researchers Michelle Duguid and Melissa Thomas-Hunt argues that this "Everyone Stereotypes" message, far from reducing bias, may act........ Read more »

The prevalence of autism spectrum disorder is not increasing in childhood

by Paul Whiteley in Questioning Answers

The title of this post is an excerpt from the paper by Sebastian Lundström and colleagues [1] (open-access) who set out to "compare the annual prevalence of the autism symptom phenotype and of registered diagnoses for autism spectrum disorder during a 10 year period in children" living in Sweden. Based on two datasets - the Child and Adolescent Twin Study in Sweden and the Swedish national patient register (NPR) - researchers analysed the records of well over a million ........ Read more »

Robot Discovers Two New Neighbors

by Perikis Livas in Chilon

Maunakea, Hawaii – A team of astronomers using ground-based telescopes in Hawaii, California, and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing their orbits in just 5, 15, and 24 days. The paper is being published in the Astrophysical Journal....

Psychologists share the three secrets to healthier eating

by Dr. Jekyll in Lunatic Laboratories

You don’t need a crazy diet to lose weight. In fact, your typical fad diet won’t help you keep weight off long term and could be harming your health. If you want to know the secrets of healthier eating, think of the kitchen fruit bowl. A fruit bowl makes fruit more convenient, attractive, and normal to eat than if the same fruit were in the bottom of the refrigerator.... Read more »

Translational Findings: How fruit flies are helping us find cures for cancer

by Bethany Christmann in Fly on the Wall

At universities and companies around the world, scientists are studying the mechanisms of cancer and tumors using fruit flies. They hope to identify failures in the genes that lead to cancer, and develop treatments to prevent or reverse these problems. Because approximately 60% of the genes associated with human cancers are shared with fruit flies, […]... Read more »

How Much Exercise Do You Really Need?

by Shawn Radcliffe in Shawn Radcliffe | Health and Science Writer

The benefits of exercise are clear, but how much should you be doing each week? And how hard should you work out? It turns out that most of us could stand to squeeze more exercise into our day. But we can probably get away with moderate exercise like walking. Exercising Lags Behind Screen Time If […]

“Chronic kidney disease (CKD) has a well-established association with impairment on neurocognitive tests, particularly measures of frontal/executive function” “MCI [Mild Cognitive Impairment] is a transitional state between normative cognitive aging and dementia. MCI is  often divided into amnestic (aMCI) form, with reduced memory performance and nonamnestic forms (naMCI), with reduced performance in cognitive domains other …

Different Dog Breeds, Different Sensitive Period?

by CAPB in Companion Animal Psychology Blog

A study of three breeds finds differences in the sensitive period, and shows socialization should begin before you even take your puppy home.Puppies have a sensitive period between 3 and 12-14 weeks old in which they must be socialized. This means positive introductions to new people, dogs, places, etc. If not, they will be fearful as adult dogs. A fascinating new study by Mary Morrow (Ohio State University) et al investigates whether this period is the same for three breeds of dog: Cavalier Kin........ Read more »

Towards a mechanistic understanding of branching innovations in plant evolution.

by Jill Harrison in the Node

Jill Harrison and Yoan Coudert.   The conquest of land by plants was one of the most significant events in our planet’s history, and was underpinned by a series of innovations in plant architecture. Amongst these, the innovation of branching stands out in allowing plants to colonize new volumes of space in the subaerial environment. […]... Read more »

The Flower Child Must Be Confused

by Mark Lasbury in As Many Exceptions As Rules

Very few animal species have true hermaphrodites, but over 90% of flowering plants are bisexual. Even though the rest are exceptions, they aren’t all the same type of exception. Some plants are male and some are female all the time, but some change sex every morning they flower. And maple tress can decide to be male or female for a whole year and then change their mind for next year.... Read more »
