"The primary finding from the study was evidence of an improvement in several objective sleep parameters in participants in whom the increased colonization of lactic acid producing organisms was resolved after antibiotic treatment."Those were the words written by Melinda Jackson and colleagues  (open-access) who, during an open-label trial, looked at whether administration of an antibiotic (erythromycin 400 mg) over the course of 6 days might have some important effects on elements of sleep i........

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 »

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.

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 »

Greenland has long held sea-level rise at bay, absorbing melted water into spongy upper layers. But new research has found that icy covers to these layers are preventing water absorption and driving water into the oceans.... Read more »

A lot of has been written about how focusing too much on materialistic ambitions, at the expense of relationships and experiences, can leave us miserable and unfulfilled. In a new paper published in Social Psychological and Personality Science, a team of psychologists at the University of British Columbia in Canada argue that there's another important distinction to be made – between how much we prioritise time versus money. Those who favour time tend to be happier, possibly because this frees........ Read more »

A recently paper published in
PNAS, members of the CEES Marine Group explores potential climate effects on
Calanus finmarchicus, a key zooplankton species in the North Atlantic. The paper shows how the combination of shallow mixed-layer-depth and increased wind apparently increases chlorophyll biomass in spring, and in turn
C. finmarchicus biomass in summer. These findings strongly suggest bottom-up effects of food availability on zoopla........ Read more »

"Vitamin D deficiency might contribute to the aetiology of ASD [autism spectrum disorder]. Supplementation of vitamin D3, which is a safe and cost-effective form of treatment, may significantly improve the outcome of some children with ASD, especially younger children."More big words have appeared from a research group who seem to be particularly interested in how vitamin D (the sunshine vitamin/hormone) might have some important links to at least some cases of autism. The findings thi........ Read more »

Genes could help in determining whether a person likes to rise early in the morning or not.
Researchers, in affiliation with 23andMe, Inc. recently worked on the DNA of 89,283 individuals, and found that genes could show some specific variations more frequently in the people, who self-identify themselves as early risers or morning people. They found 15 different spots in the genetic makeup that can vary between morning........ Read more »

At the heart of the Great Lakes region of East Africa is Tanzania — a republic comprised of 30 mikoa, or provinces. Its border is marked off by the giant lakes Victoria, Tanganyika, and Malawi. But the lake that interests me the most is an internal one: 200 km from the border with Kenya at […]... Read more »

The findings reported by Ciro Marangoni and colleagues  made for some interesting reading recently and their systematic review of longitudinal studies looking at the various environmental exposures put forward as possible risk factors pertinent to the development of bipolar disorder (BD).Trawling through the peer-reviewed material on this topic, the authors were able to 'clump' the various proposed risk factors into one of three categories: "neurodevelopment (maternal influenza during pr........

Depression is a serious issue for expecting mothers. Left untreated, depression could have implications for a fetus’s health. But treating the disease during pregnancy may carry health risks for the developing fetus, which makes an expecting mother’s decision whether to take medication a very difficult one. To better understand how antidepressants affect fetuses during pregnancy, scientists studied exposure in mice.

In the U.S., people face 25 times more chances of being killed by guns as compared to many other developed nations.

In a study on “violent death rates”, researchers have reported that the rate of gun-related murder in the U.S. is about 25 times higher as compared to 22 other high-income countries. Moreover, gun-related suicide rate in the U.S. is about 8 times more than other high-income nations;........ Read more »

I decided to look for something I wrote that I have been wrong about. I thought about Masimo and their RAD-57. I had been very critical of Dr. Michael O’Reilly (then Executive Vice President of Masimo Corporation) for being an advocate of bad science, but he has been hired away by Apple. He should be less dangerous with a telephone than he was with the RAD-57. At the time, he wrote –... Read more »

In our part of the world, a growing proportion of fathers are rolling up their sleeves and getting involved in early child care. This has prompted increased interest from psychologists in any similarities or differences in the way that mothers and fathers interact with their children. One finding is that fathers tend to engage in more physical play, whereas mothers spend more time playing with toys and interacting socially. A new study in the Quarterly Journal of Experimental Psychology takes a ........ Read more »
