I've been doing this whole parenting thing for almost three months now and it has been simultaneously gratifying, terrifying, exhausting, and fascinating. One thing I haven't been doing is sleeping, and because of this I have had a lot of time to read up on some neat research on new parents. Last time I wrote about how parenting reduces Testosterone in men. Today I blog about the relationship between parenting and immune function.
Can parenting boost the immune system?

A group of scientists from the Ulsan National Institute of Science and Technology (UNIST), Korea, has developed a new metal-free fuel cell catalyst using edge-halogenated graphene nanoscale platelets. As a replacement for the expensive platinum-based catalysts this graphene application opens a way to affordable fuel cells.... Read more »

In the year 2006 'google' was officially declared a verb in Oxford Dictionary and Merriam Webster. But startups have not given up on building search engines. That same year Facebook opened its doors to users over the age of 13, preparing for exponential growth spurt. The list of startups working on yet another social network and lining up to present their sites at Silicon Valley New Tech Meetup kept growing too. And so were the crowds attending the meetups - as everybody wanted to see the next ........ Read more »

Communication between cells takes many forms. There could be communication by sending out microvesicles with important messages inside, by sending out free molecules (like hormones) or by special structures (e.g. synapses). Sonic hedgehog (SHH) is a signaling protein that is important … Continue reading →... Read more »

Blinkers and non-blinkers have individual differences in selective attention and the ability of the non-blinkers to sense the targets presented in close temporal succession might be due to fairly quicker and exact target selection process.
Many people are unable to respond to the second target when presented in close time to the first (200-500 ms interval) and this phenomenon is known as attentional blink (AB). This concept is in r........ Read more »

When people think of mental problems related to body image, often the first thing that comes to mind is the thin figure associated with anorexia. Body dysmorphic disorder is less well known, but has around five times the prevalence of anorexia (about 2% of the population), and a high level of psychological impairment. It’s a mental disorder where the main symptom is excessive fear of looking ugly or disfigured. Central to the diagnosis is the fact that the person actually looks normal.... Read more »

A collaboration between Oak Ridge National Laboratory researchers and a team led by the Carnegie Institution for Science’s Malcolm Guthrie has led to discoveries about how ice behaves under pressure, changing ideas that date back almost 50 years. The findings could alter scientists’ understanding of how the water molecule responds to conditions found deep within planets and could have implications for energy science.... Read more »

If someone told you to put your rock hard green McIntosh apple with a banana as that would make it ripe, you sure would scoff a little. But, believe your ears and do that yourself. It’s an easy way to get that red juicy goodness without spending a single penny! It sounds like magic – but it’s pure science.

For the first time, researchers have found that stress can leave an epigenetic mark on sperm, which then alters the offspring’s hypothalamic-pituitary-adrenal (HPA) axis, a part of the brain that deals with responding to stress. The study was published in the Journal of Neuroscience.
The experiment was conducted with preadolescent and adult male mice, in which stress was induced – for example by confronting the mice with predator odor (fox urine) or foreign objects in their cages......... Read more »

Keeping it real often means hanging out
From Ancient Greek philosophy to humanistic psychology to modern day rap songs, there's a long tradition of espousing the benefits of being true to yourself or "keeping it real". Despite this interest, a new study by Alison Lenton is one of the first to investigate what being true to oneself actually feels like, how often it happens and in what circumstances.
Lenton and her colleagues began by surveying 104 participants (average age 35; 66 women) on th........ Read more »

It's the usual excuse from me, "the dog ate my homework sir", no not that one, the one about me having a busy week so not being able to post a particularly detailed blog entry this time around.

I seldom get worked up over the fate of fictional characters. That said, I joined millions in horror as the infamous Red Wedding (or “Rains of Castarmere”) finally unfolded on screen in last week’s Game of Thrones.

A flaw in data processing could be leading to biases in fMRI brain functional connectivity patterns, according to a new report: The Nuisance of Nuisance Regression. Ironically, two high-profile recent papers about bias are amongst the victims. The new paper, from Pittsburgh’s Michael Hallquist and colleagues, is essentially about a case where 2 + 2 [...]...

After approximately two months of preparations in Kiruna in the north of Sweden, the balloon-borne solar observatory Sunrise has lifted off successfully today at 7.37 a.m. CEST. For one week the team has been waiting for favorable weather conditions. Polar winds will now grasp the huge, helium-filled balloon and the gondola, carrying Sunrise westward around the North Pole at a height of more than 35 kilometers. Equipped with the largest solar telescope ever to have left the Earth’s surface........ Read more »
