A new study, which followed 180 preterm infants from birth to age seven, found that babies who were fed more breast milk within the first 28 days of life had had larger volumes of certain regions of the brain at term equivalent and had better IQs, academic achievement, working memory, and motor function.

Science headlines eh? Who would trust them and their sometimes inflated press releases?I start today with a science headline taken from the BBC website reading: "Pregnancy multivitamins 'are a waste of money'" based on the findings of a review article  published in the journal Drug and Therapeutics Bulletin.In it we are told that complex multi-vitamin and mineral supplements are 'unlikely to be needed and are an unnecessary expense' during the nine months that made us. Further that certain vi........ Read more »
Medication roulette, if you have ever had to deal with depression or other types of mental illness you know what I'm talking about. You take a pill that could help or could cause all sorts of horrid side effects. You cross your fingers as you take that first pill and in the 4-6 weeks it takes to start working you cross your fingers, hope, wish and probably even dread the outcome. But why does it take so long for antidepressants to start working in the first place and what could be done to c........ Read more »

Gron gazed across the plain from inside a tuft of long grass. There. Just in front of the far hillock. Gazelles. Meals on legs.

The paper by Traolach Brugha and colleagues  makes for some blogging fodder today and the suggestion that: "The combined prevalence of autism in adults of all ages in England was 11/1000."Just before going through the Brugha paper it is perhaps appropriate to put it into some context based on other work from this group previously covered on this blog (see here) and the findings again by Brugha and colleagues  (a further report on their findings that time around can be seen h........

If you're ever lost in a remote European forest, you might be able to get your bearings by finding a herd of roe deer. These animals like to align themselves roughly north-south, whether they're standing still or fleeing danger.
Roe deer are small, reddish or grayish grazers common in Europe and Asia. Petr Obleser, of the Czech University of Life Sciences in Prague, and his coauthors studied the behavior of these skittish herbivores to look for evidence that they can sense the earth's ma........ Read more »
In a new paper that could prove explosive, Australian neuropathologists C. V. Dennis and colleagues report that they found very little evidence for adult neurogenesis in humans.
In recent years, the idea that neurogenesis - the production of new neurons - occurs in specific regions of the adult brain has become widely accepted, and much discussed. Disruptions to neurogenesis have been proposed to play a role in stress, depression, and other disorders.
However, Dennis et al. say that ne... Read more »

Human papillomaviruses (HPV) are a diverse group of small double-stranded DNA viruses with specific mucosal or cutaneous tropisms. It is estimated that up to 80% of sexually active individuals will become infected with HPV sometime in their lifetime, making HPV the most prevalent sexually transmitted infection. HPVs can be further divided into high- and low-risk genotypes, based on their oncogenic potential. High-risk HPVs are implicated as causal in nearly 100% of cervical cancers, approximatel........

One the tenets of science is that hypotheses can't be proved, only disproved. But medical journals do not publish negative data, even though this is often helpful to scientists and physicians. A recent TED Talk by Ben Goldacre illustrates this point in the context of drug studies. In a bigger sense – is this really the only way to do science; to follow this one scientific method?...

"The meta-analysis provided evidence for higher blood glutamate levels in ASD [autism spectrum disorder]."That was the research bottom-line reported by Zhen Zheng and colleagues  (open-access available here) who surveyed the current peer-reviewed science literature in this area and found something to see based on: "Twelve studies involving 880 participants and 446 incident cases."Drawing on the idea that glutamate is a rather important amino acid that plays a role in various biological p........

Morels and several other fungi (all members of the order Pezizales) are known to produce their mushrooms in recently burned soil, whether it's the result of a nice little campfire or an entire forest going up in smoke. The fire creates the right conditions for the fungus, which lies beneath the ground and so protected from flames and heat, to send up mushrooms. These mushrooms release spores into the environment, and the circle of life continues ever onward.In the case of morels, it's thought a ........ Read more »

The fountain of youth may reside in an embryonic stem cell gene named Nanog. In a series of experiments, the gene kicked into action dormant cellular processes that are key to preventing weak bones, clogged arteries and other telltale signs of growing old. The findings also show promise in counteracting premature aging disorders such as Hutchinson-Gilford progeria syndrome.

I very carefully approach the findings reported by Jennifer Fairthorne and colleagues  today detailing "the occurrence of hospital admissions and treatment/services for cancer in mothers of children with ASD [autism spectrum disorder] with or without ID [intellectual disability] compared with other mothers."

Capitalizing on experimental genetic techniques, researchers have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain. The research suggests that alterations in the functional connectivity of the brain in humans may be used to determine the sites of pathology in complex disorders such as schizophrenia and autism.
