Comparative analysis of regulatory information and circuits across distant species

by Franziska Gruhl in genome ecology evolution etc

Development and homeostasis of all organisms is tightly controlled by transcription regulatory factors that are often highly conserved across deep phylogenies. However, it is unclear to what extend the basic components of these networks (e.g. network motifs and structure, binding … Continue reading →... Read more »

Subduction is not the end

by Metageologist in Metageologist

Subduction is just the beginning. Stuck on the surface of the earth as we are, it’s easy to think that when oceanic lithosphere is destroyed when it vanishes into the mantle. But this is wrong. The more we manage to peer … Continue reading →... Read more »

When it comes to sleep recommendations, what about the children?

by Gabriel in Lunatic Laboratories

Sleep is a hot topic lately, are we getting too much, too little, how much is enough? However, most of these questions are for adults, so what about children? Well as it turns out a new study used activity monitors to track how sleep habits changed in younger and older teens as they grew during a two-year period. Key findings from this study has also lent t0 new support to recent recommendations by the American Academy of Pediatrics that middle and high schools avoid starting earlier than 8:30 a........

Are we really evolving into super-humans?

by EE Giorgi in CHIMERAS

© EEGI came across an article on the Popular Science website, which, turns out, is the excerpt of a new book on evolution by Science Guy Bill Nye. From the reviews I gather that Bill Nye is an excellent writer and, being also an entertainer, he knows how to not only expose well but also infuse some good humor to what he says. That's all fantastic. But while the article starts off with some rigor, his conclusion had me roll my eyes. Because, even though he does include some speculations th........ Read more »

UK Millennium Cohort Study: School and the disabled child

by Paul Whiteley in Questioning Answers

Quite recently the BBC News online ran with the headline: "Disabled children's behaviour 'deteriorates at school'". The story revolved around the findings reported by Rebecca Fauth and colleagues [1] (open-access) looking at "the extent to which the associations between disability and behaviour are linked to children’s developmental stage and thus may be ‘grown out of’ as children enter school and move out of the early years". I should add that, at the time of writing, the Fauth paper is d........ Read more »

Bernstein polynomials and non-linear public goods in tumours

by Artem Kaznatcheev in Evolutionary Games Group

By analogy, or maybe homage, to standard game theory, when we discuss the payoffs of an evolutionary game, we usually tell the story of two prototype agents representing their respective strategies meeting at random and interacting. For my stories of yarn, knitting needles, and clandestine meetings in the dark of night, I even give these […]... Read more »

It hurts! Atheists and Christians don’t feel each others pain, but with a twist.

by Tom Rees in Epiphenom

For many people, their religion is like a badge of social identity. You feel an affinity with people who share a religion – not surprising given that you will share many cultural and social touch points. But will you feel their pain? If shown a picture of a Christian grimacing, will you mentally flinch? What about [Read More...]

Breaking Research: A method by which invading bacteria avoid detection could also be our key to defeating them

by Bethany Christmann in Fly on the Wall

Have you ever wondered how our body recognizes when it’s being invaded by harmful bacteria? Nearly all forms of life—from single-celled organisms all the way to humans—have an “innate” immune system, which has evolved to recognize cellular components shared by broad groups of pathogens. One such example is peptidoglycan, a molecule found on the cell […]... Read more »

Powerful Ravens Sabotage Others’ Relationships

by Elizabeth Preston in Inkfish

  If we’re lucky, this is behavior we haven’t seen since high school. The coolest individuals can’t stand to see others gaining social status, so they cut down any peers who are starting to elevate themselves. Ravens have to live with this behavior all the time. When the top-dog birds see others building new relationships, […]The post Powerful Ravens Sabotage Others’ Relationships appeared first on Inkfish.... Read more »

You can tell a lot from looking at someone’s face…

by Rita Handrich in The Jury Room

Our mock jurors (and many others as well) tend to believe the eyes are the “window to the soul” and that by simply looking at the eyes of another, they can intuit truthfulness and character. But it can be even easier! Just look at the face and you can actually assess introversion/extroversion, competence/incompetence, dominance/submission, and […]

When we get depressed, we lose our ability to go with our gut instincts

by BPS Research Digest in BPS Research Digest

People who are depressed often complain that they find it difficult to make decisions. A new study provides an explanation. Carina Remmers and her colleagues tested 29 patients diagnosed with major depression and 27 healthy controls and they found that the people with depression had an impaired ability to go with their gut instincts, or what we might call intuition.Intuition is not an easy skill to measure. The researchers' approach was to present participants with triads of words (e.g. SALT DEE........ Read more »

Diving into Energy Drinks

by Wiley Asia Blog in Wiley Asia Blog - Life Sciences

How much do you know about energy drinks? We always consume energy drinks to boost our mood in general and to enhance our physical endurance. Being consumed since 1960s in Europe and Asia, we are uncertain about the side effects that energy drinks could produce.

While energy drinks are consumed by general consumers, teenagers and young adults are targeted group of consumers. The researchers analysed various ingredients that usually contain in energy drinks as well as the market size and safet........ Read more »

A Possible Genetic “Cure” for HIV… Maybe

by Gabriel in Lunatic Laboratories

Let’s face it, a cure for HIV probably won’t be coming around for awhile. That slippery little virus manages to avoid everything we throw at it. Well researchers at Massachusetts General (MGH) and Boston Children’s hospitals (BCH) tried to take another crack at the problem. For the first time they have used a relatively new gene-editing technique to create what could prove to be an effective technique for blocking HIV from invading and destroying patients’ immune systems....
