Small animals in a big forest

by Diego in macrostylis

Small animals in a big forest
Recognizing different species is crucial for all zoological studies. The study of many animal groups went through different periods with new data changing established beliefs about the number and distribution of known species. Recently, one more piece of story has been added to the history of tardigrade genus Milnesium, a new species living in the tree canopy.

After learning to identify with someone else's face, do people think their appearance has changed?

by BPS Research Digest in BPS Research Digest

Past research has shown that it’s possible to hack our sense of our own bodies in bewildering ways, such as perceiving another person’s face as our own by stroking both in synchrony. These body illusions can alter our sense of self at a psychological level too. For example, embodying a child-sized body in a virtual reality environment leads people to associate themselves with child-like concepts. Can such effects also operate in the opposite direction, from the psychological to the physical?........ Read more »

Shared genetics? Autism, gastrointestinal issues and serotonin

by Paul Whiteley in Questioning Answers

I note the paper by Kara Gross Margolis and colleagues [1] (open-access available here) has been garnering a few media headlines with the suggestion that: "Gastrointestinal [GI] problems in autistic children may be linked to the same genetic mutations that cause other characteristics of autism spectrum disorder."The study, focusing on the idea that SERT (the serotonin transporter) encoded by the SLC6A4 gene might show some connection to 'some' autism [2], looked to model........

ZIKV infection of brain organoids: role of TLR-3 induced apoptosis due to changes in gene expression?

by thelonevirologist in Virology Tidbits

During the current outbreak of ZIKV in Brazil, ZIKV RNA was detected in amniotic fluid samples of women infected with ZIKV during pregnancy and ZIKV RNA has also been isolated from tissue (brain and CNS) of neonates born with microcephaly, suggesting that ZIKV infection of the mother might be a contributive factor in the observed increase of microcephaly cases in neonates. In addition to microcephaly, miscarriages have also been reported in ZIKV positive pregnant women, especially during the fir........ Read more »

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.

How to Solve Homicide Crimes

by William Yates, M.D. in Brain Posts

Homicide rates in the U.S. represent a significant public health challenge. Homicide is a top ten leading cause of death in many groups in the U.S.One method to reduce homicide rates is to quickly identify and arrest individuals who have committed homicide. This is due to the fact that individuals committing homicide have a high rate of future homicide.A recent study from Michigan State University and Indiana University examined characteristics of U.S. police departments that have high rates of ........

Dietary Seafood and Cognitive Decline

Seafood intake has been linked to a variety of improvements in health. Additionally, there is some evidence linking seafood intake with slower cognitive decline in aging populations.A recent study adds to this age-related cognitive benefit of seafood intake.A collaborative group of researchers from Rush University Medical Center and the Wageningen University in the Netherlands conducted a prospective study.This study followed 915 subjects with a mean age of 81.4 years over a five year period.

A new report finds there are 11 dog attacks on guide dogs every month in the UK, on average.The lifetime cost of a guide dog for the blind is approximately US$75,000Guide dogs provide essential assistance to people who are blind or partially sighted. When other dogs attack guide dogs, the consequences can be severe. The charity Guide Dogs has been keeping records of these attacks, and a new paper by Rachel Moxon (of Guide Dogs) et al details the problems faced over a 56 month period from 2010 to........

Viva La Evolution

In our continuing story of how being sick can save you, how about three genetic diseases and a genetic condition that can save you from malaria. The genetic diseases might kill you, but usually after you procreate, and that is better for the species than being killed by malaria as a child. Evolution is an emotionless mistress.... Read more »

Why do women do so much better at university than their school test scores predict?

by BPS Research Digest in BPS Research Digest

Picture an American high school staff-room, late in the academic year, where a teacher called Alice is listening to her colleagues ride their favourite hobby horse: picking out which students have the most promise.Eventually Alice leans forward and taps her laptop. “Less talk, guys, more data. If you want to know how a student will do when they get to college, look at their aptitude test scores.” Betty throws her a look. “That won’t work,” she says, ”girls go on to do better than the........

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.
