We can build it better: Synthetic biopathway turns agriculture waste into ‘green’ products

by Dr. Jekyll in Lunatic Laboratories

Researchers at the University of Minnesota have engineered a new synthetic biopathway that can more efficiently and cost-effectively turn agricultural waste, like corn stover and orange peels, into a variety of useful products ranging from spandex to chicken feed.

Why Ask for Directions? (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

by Anna Schneider For the iconic monarch butterfly, the shorter days in fall mean it’s time to pack up and head south to a warmer climate! Just like clockwork, the Eastern population of monarch butterflies makes a 2000 mile journey to their winter paradise roosts in central Mexico. The journey in itself is one of the greatest migrations among all animals. But here’s the catch: none of these butterflies has made this trip before. Several generations of monarchs have come and gon........ Read more »

Rare Variant Studies of Common Disease

by Daniel Koboldt in Massgenomics

Not so long ago, there was a hope in the research community that common genetic variation, i.e. variants present at minor allele frequencies >5% in human populations, might explain most or all of the heritability of common complex disease. That would have been convenient, because such variants can be genotyped with precise, inexpensive, high-density SNP […]... Read more »

How the home crowd affects football referees' decisions

by BPS Research Digest in BPS Research Digest

One of the most thorough investigations into referee bias has found that they tend to award harsher foul punishments to the away team. The new results, published in the International Journal of Sport and Exercise Psychology, suggest that experienced referees are just as prone to this bias as their less experienced colleagues.Andrés Picazo-Tadeo and his team analysed data from 2,651 matches played in the First Division of La Liga, the Spanish Football League between the 2002/3 and 2009/10 season........

by Usman Paracha in SayPeople

Main Point:

Decreased or disturbed sleep can result in poor performance of students in school.

Published in:

Journal of Sleep Research

Study Further:

In a study, researchers from Norway (and their collaborators) worked on the affect of sleep duration and its pattern on the academic performance of adolescents in the age range of 16 years to 19 years. Researchers surveyed 7798 adolescents, of whom 53.5% were girls. In the survey, researchers asked them about sleep duration, its effi........ Read more »

"People with ASD had lower odds of employment in the community"

by Paul Whiteley in Questioning Answers

The title of this quite brief post refers to an important finding detailed by Derek Nord and colleagues [1] who, when analysing data from the "2008–09 National Core Indicators Adult Consumer Survey", concluded that there were some important inequalities when it came to employment rates for those diagnosed on the autism spectrum.Employment rates and work opportunities for people diagnosed with an autism spectrum disorder (ASD) is a hot topic at the moment. The Nord findings build upon report af........ Read more »

The molecular link between psychiatric disorders and type 2 diabetes

by Dr. Jekyll in Lunatic Laboratories

There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.

Brain plasticity assorted into functional networks

by Dr. Jekyll in Lunatic Laboratories

Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

Zika Virus, Microcephaly and Brazil

by thelonevirologist in Virology Tidbits

As discussed before, Zika Virus (ZIKV) is an emerging arbovirus, spread by Aedes Agypti and Aedes albopictus, which was first isolated in 1947 in Uganda from a Macaca monkey with the first human case being detected in Nigeria (1954). In subsequent decades sporadic cases linked to ZIKV have been reported in Africa and Asia, with a first epidemic reported in 2008 (Yap/Federated States of Micronesia) and a larger one in French Polynesia and Oceania 2013-2014 with the first cases in the Americas wer........

"Troubling Oddities" In A Social Psychology Data Set

by Neuroskeptic in Neuroskeptic_Discover

A potential case of data manipulation has been uncovered in a psychology paper. The suspect article, Why money meanings matter in decisions to donate time and money, came out in 2012 from University of Arizona psychologists Promothesh Chatterjee, Randall L. Rose, and Jayati Sinha.

This study fell into the genre of 'social priming', specifically 'money priming'. The authors reported that making people think about cash reduces their willingness to help others, while thinking of credit cards has... Read more »

Do songbirds perceive melody different from humans?

by Henkjan Honing in Music Matters

Last week a fascinating study appeared in PNAS on melody cognition in sparrows (Sturnus vulgaris). It provides an alternative interpretation to the widespread believe that songbirds have a strong bias to rely on absolute pitch (AP) for the recognition of melodies (e.g. Hulse et al., 1992)....

Would You Stick Pins In A Voodoo Doll of Your Child?

by Neuroskeptic in Neuroskeptic_Discover

Well? Would you...?

This was the question faced by the participants in a rather extraordinary series of studies described in a new paper from Illinois psychologists Randy J. McCarthy and colleagues. In total, 1081 parents with children aged under 18 were presented with an outline of a person, and asked to imagine that it was their own child. They were told to think of a time when their child made them angry. Finally, they were asked how many pins they would like to stick into the "doll" in or... Read more »

Man-made underwater sound may have wider ecosystem effects

by Dr. Jekyll in Lunatic Laboratories

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton. The study found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

Four Legs Good, Two Legs Better for Hurdling Obstacles

by Elizabeth Preston in Inkfish



Although lizards mostly scurry on all fours, certain species can run on two legs when the mood strikes. What's the benefit to this human-like running style? For one thing, it seems to let lizards get over obstacles without slowing down. They just have to make sure not to tip over.

Georgia Southern University biologist Lance McBrayer and graduate student Seth Parker studied running in a handsome little reptile called Sceloporus woodi, or the Florida scrub lizard. McBrayer says there's been... Read more »

TSC2 mutations confer everolimus sensitivity in hepatocellular carcinomas

by Danielle Stevenson in BHD Research Blog

Hepatocellular carcinomas (HCCs) are the third leading cause of cancer deaths globally; frequently diagnosed only in the advanced stages and aggressive in nature. Although enhanced mTOR activity has a key role in HCC tumourigenesis, the EVOLVE-1 clinical trial of mTOR inhibitor everolimus found no associated improvement in overall survival (Zhu et al., 2014). However, everolimus is an effective treatment for tuberous sclerosis complex (TSC) manifestations, a rare disease associated with mutation........ Read more »

Cross-cultural studies of toddler self-awareness have been using an unfair test

by BPS Research Digest in BPS Research Digest

There's a simple and fun way to test a toddler's self-awareness. You make a red mark (or place a red sticker) on their forehead discreetly, and then you see what happens when they look in a mirror. If they have a sense of self – that is, if they recognise themselves as a distinct entity in the world – then they will see that there is a strange red mark on their face and attempt to touch it or remove it.This is called the "mirror self-recognition test" (it's used to test self-awareness in ani........
