2:34 PM | An unusual form of diabetes may be caused by drinking arsenic-contaminated water
Like a careless criminal, even small amounts of toxic arsenic leave telltale fingerprints on victims’ bodies—although these fingerprints are different if the victim as Type 2 Diabetes, scientists report. And arsenic has many potential victims: more than 200 million people worldwide … Continue reading →

5:38 AM | Interoception and body awareness in autism
"Interoception: the sense of the physiological condition of the body" [1].This was an important concept detailed in the paper by Lisa Fiene and Charlotte Brownlow [2] with autism in mind. Looking at how adults diagnosed with an ASD (autism spectrum disorder) "interpret elements of the interoceptive sense, which includes thirst, hunger, temperature, satiety" researchers questioned those on the spectrum (n=74) and asymptomatic controls (n=228) with "self-reported perceptions of body […]

5:36 PM | Neuronal disorders and energy metabolism
Scientists in Japan have have discovered how nerve cells adjust to low energy environments during the brain’s growth process. Their study may one day help find treatments for nerve cell damage and neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases. Neurons in the brain have extraordinarily high energy demands due to its complex dendrites that expand […]

9:01 PM | ¿Porqué ocurre la Violencia Sexual?

5:58 PM | A glass fiber that brings light to a standstill
Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place.

12:06 AM | The universe is expanding, but how fast?
We are expanding, well more accurately the universe is expanding. However researchers have found certain types of supernovae, or exploding stars, are more diverse than previously thought. The results have implications for big cosmological questions, such as how fast the universe has been expanding since the Big Bang. Most importantly, the findings hint at the possibility that […]

Rape, it’s so taboo that victims are sometimes shamed for “letting” it happening. It’s a dirty word, no one likes the word rape so we come up with other names for it — sexual assault for example. Well new research shows that close relatives of men convicted of sexual offences commit similar offences themselves more frequently […]

7:31 AM | Effects of prenatal organophosphate pesticide exposure on a mouse model of autism
Pesticides and autism is a topic previously covered on this blog (see here for example). The idea that some of the various preparations that we use to control the pests which have an ability to blight our crops or cause serious health issues could be linked to an increased risk of autism is an area likely to invoke some divisions within elements of the autism and wider scientific community.Part of the problem with the available evidence suggesting a link between autism and pesticide exposure is […]

12:30 PM | Why Do People Relinquish Large Dogs?
When someone gives up a large dog to a shelter, what are the usual reasons?Research by Emily Weiss (ASPCA) et al looks at why people relinquish large dogs – and whether there are interventions that could have helped the animal stay in its home. The results show that people issues, rather than dog issues, are given as the main reason. They also highlight that owners have many good things to say about their dog, even as it is relinquished.In the US, large dogs are at a greater risk of […]
