This post might well fall into the category of “the route to tenure-track publication credits is not always the high road”. We discard lots of dicey research reports (such as this one) because they add nothing to our goal of improving litigation advocacy. But this one was so weird we found it amusing. Enjoy. But […]

Sympathy towards the suffering is culture-dependent. People from "simpatico" cultures such as Brazil or Costa Rica are more likely to help people in need, as are people from economically poorer nations compared to wealthier counterparts. Now new research explores differences in how sympathy is expressed within two Western countries. Americans encourage sufferers to look for the light at the end of the tunnel, the study finds, while Germans are more comfortable gazing at its dark walls.Birgit Koo........ Read more »

"In summary, this work has demonstrated the potential value of long-term probiotic-based interventions to counter mercury and arsenic exposure in vulnerable populations, particularly in pregnant women".Sounds like an '80s man to me...That was one of the primary conclusions reported by Jordan Bisanz and colleagues  (open-access) examining "at-risk populations of pregnant women and in children in Mwanza, Tanzania".

Adolescent cannabis use has been linked to risk of psychosis in a number of studies. However, the question of whether cannabis use actually causes some people to become psychotic is a difficult one to answer and the evidence remains inconclusive. Furthermore, long-term studies on cannabis use have generally not considered that personality characteristics that have been linked to mental illness might also prompt a person’s decision to use drugs such as cannabis....

Our recent study on maerl sediment dynamics has found that the settling velocity of maerl is primarily governed by the grain shape properties of maerl. A grain shape parameter known as the convexity has been linked to the settling velocity via the Ferguson and Church model (Ferguson and Church, 2004). Due to the grain shape of maerl and roughness, it experiences a greater drag than the natural quartz grain. Detailed measurements of maërl grain shape using microscopic image analysis confirm ........ Read more »

A great deal is known about how we make simple decisions, right down to the way neurons in our brains connect to translate the things we sense into the responses we make. Some of the most important neural studies of decision-making have used monkeys as an analogue for humans. The broader scope of methodology which can be used with primates has provided information far beyond that obtainable from human experimentation. However, conclusions based on animal experiments may not always translate to h........ Read more »
Genetic engineering techniques offers many different promises, some of which will obviously come sooner than others. One of those promises was a possible end to famine, while most famine in the world today is in developing countries, that could spread as population increases. To that end scientists have announced a new way to dramatically increase crop yields by improving upon Mother Nature's offerings. The team has discovered a set of gene variations that can boost fruit production in the tomat........ Read more »

A stumbling block to moving forward with recovery in the UK is lack of agreement about what recovery actually is. Highly specific definitions (e.g. recovery = abstinence) can lead to exclusion and fierce disagreement while non-specific definitions are too woolly to measure in services which are being asked to deliver measurable outcomes. Professionals and recovering people Professionals are [...]

Cyborg © EEGAs many of you know, one of my favorite topics here on the blog is epigenetic inheritance, i.e. the mechanisms that regulate changes in gene expression that can be passed from one generation to the next. Epigenetics has revolutionized the way we look at genetic inheritance: Darwin had taught us that the only way the environment can shape the genome of a species is through natural selection. While this is certainly still true, today we also know that:1) Most of the mutations we see i........ Read more »

HIV is hard to get rid of,not because it primarily resides in the blood, but because of where it hides when antiretrovirals drop HIV levels. So the real question is where does HIV hide? Unfortunately those antiretroviral drugs can usually control the virus, but can’t completely eliminate it. So any strategy to eradicate HIV from the body has to take into account not only the main group of immune cells the virus targets, called CD4 or helper T cells, but other infected cells as well....

The promises of genetic modifications are endless, longer life, better health, cures for genetic based diseases that would otherwise cause an unimaginable amount of suffering all wiped out. We’ve come a long way in genetic alteration thanks, in part, to the ever faster moving pace of science.

In the 1980s, a few studies came out suggesting that patients with bulimia nervosa (BN) require fewer calories for weight maintenance than anorexia nervosa patients (e.g., Newman, Halmi, & Marchi, 1987) and healthy female controls (e.g., Gwirtsman et al., 1989).
