Fish, mercury, and pregnancy: Good news for seafood lovers

by Dr. Jekyll in Lunatic Laboratories

People freak out when they hear mercury is in something and sometimes for good reasons. In vaccinations for example a very small amount of ethyl-mercury WAS used as a preservative in vaccines, people got scared so now it is not used in most vaccines. Methylmercury* however is found in seafood and larger fish in particular (in much, much higher concentrations than in vaccines mind you). They may sound the same, but the methylmercury in fish is far more toxic. That said, it turns out that fish isn........ Read more »

Porcine Respiratory Syndrome Virus (PRRSV) and autophagy: a link between the ER stress response and p53?

by thelonevirologist in Virology Tidbits

Porcine reproductive and respiratory syndrome virus (PRRSV) is an enveloped virus with a positive strand ssRNA genome of approx. 15kB in length, encoding for ten open reading frames (ORFs).
Similar to the genome of the Coronaviridae, the PRRSV genome ORF1a and 1b genes encode for a RNA-dependent RNA Polymerase as well as for a number of non-structural proteins (nsp; 12 in total) which are generated by autoproteolytic cleavage by a virally encoded cysteine protease (nsp2), serine protease (nsp4........

Polar Bears Leave Messages in Their Footprints

by Elizabeth Preston in Inkfish



If a polar bear tells you to talk to the hand, don't be offended. The animals seem to communicate with each other through scent trails left by their paws. Their tracks tell a story to the other bears roaming their habitat, helping potential mates to find each other—as long as there's habitat left, anyway.

As they crisscross the snowy Arctic, polar bears are usually alone. In other solitary bear species, animals leave messages for each other by rubbing their bodies or urine onto trees or........ Read more »

Then and now: Beepers versus iPhones  [and separation anxiety]

by Rita Handrich in The Jury Room

Back in the early ‘90s, I had a job that required me to carry a beeper. The constant awareness that I was “on call” was a source of strain and led me to complain I was never really “off duty”. Flash forward to this century and I cannot imagine being without my smart phone. In […]

Video Tip of the Week: GWATCH, for flying over chromosomes

by Mary in OpenHelix

Ok, so it’s not *just* for flying over chromosomes. There’s more to it, of course. But that’s the part of GWATCH (Genome-Wide Association Tracks Chromosome Highway) that caught my attention. I’m always looking for different ideas and strategies to visualize data, and this was the first time I drove along the whole length of a […]... Read more »

Evolving A Second Job

by Mark Lasbury in As Many Exceptions As Rules

Centrioles are the most amazing structures in your cell. They don’t have DNA, yet they duplicate to form more of themselves or they can form spontaneously if lost. They control the beating direction of the cell’s cilia; change one’s direction and all of the cells for hundreds of generations will remain moving in the wrong direction.... Read more »

What do confident people say to themselves before giving a speech?

by BPS Research Digest in BPS Research Digest

Before you speak to an audience, can you first talk yourself out of feeling nervous? One step towards this strategy is to find out how confident people speak to themselves in their heads (their internal "self-talk"), compared with others who are more anxious.Xiaowei Shi and his colleagues surveyed nearly 200 students on a public speaking course. The researchers approached the students after they'd given two public presentations on the course and were soon to give their third. The students answer........ Read more »

Truthiness of irrelevant detail in explanations from neuroscience to mathematical models

by Artem Kaznatcheev in Evolutionary Games Group

Truthiness is the truth that comes from the gut, not books. Truthiness is preferring propositions that one wishes to be true over those known to be true.

You can live longer, but not healthier

by Dr. Jekyll in Lunatic Laboratories

We all want to live longer and thanks to medical technologies our life expectancies have dramatically increased. Which would be handy if we could actually enjoy the extra years. Unfortunately a study of long-lived mutant C. elegans by scientists shows that the genetically altered worms spend a greater portion of their life in a frail state and exhibit less activity as they age than typical nematodes. These findings suggest that genes that increase longevity may not significantly increase healthy........ Read more »

Misconceptions Never Die. They Just Fade Away.

by Joshua Fisher in Text Savvy

In a post on my precision principle, I made a fairly humdrum observation about a typical elementary-level geometry question:

Why can we so easily figure out the logics that lead to the incorrect answers? It seems like a silly question, but I mean it to be a serious one. At some level, this should be a bizarre ability, shouldn't it? . . . . The answer is that we can easily switch back and forth between different "versions" of the truth.... Read more »

The Electrical Grid Needs Fattening Up

by Mark E. Lasbury in The 'Scope

Make hay while the sun shines is the great lesson from renewable energy. Solar and wind have to be harvested when they occur, or they are lost forever. But how do you store that energy if the national grid doesn’t need it at that moment? Large-scale energy storage is the wave of the future – including pumping air or hydrogen gas into abandoned mines or running the national grid from all our electric cars.... Read more »

When our beliefs are threatened by facts, we turn to unfalsifiable justifications

by BPS Research Digest in BPS Research Digest

On being told physics could underminereligious claims, believers said faithwas more about living a moral lifeIt's great to have facts on your side. The fundamentalist is delighted by the archaeological find that tallies with scripture, just as the atheist seizes on the evidence that contradicts it. But when the evidence goes against us, we're less likely to change a belief than to criticise the validity or provenance of the evidence. Now, research suggests that the mere prospect of a factua........ Read more »

Autism and low vitamin D at birth

by Paul Whiteley in Questioning Answers

Discussions about vitamin D (the 'sunshine' vitamin/hormone) and autism are not unfamiliar to this blog. Just last year (2014) I covered research talking about the possibility of a connection between vitamin D and [some] autism at least three times (see here and see here and see here), possibly more...but in my game, I'm the bad guy, and I live in the garbage.I wouldn't say that I'm an advocate for everything implied by the correlations being made between vitamin D levels and autism given that v........
