The Anthrome Era

by Journal Watch Online in Journal Watch Online

Cities are growing – and so too is the study of urban ecosystems. A hefty new review finds that, after decades of disinterest, ecologists are piling up new insights into how urbanization can influence everything from soil bacteria to bird calls. Now, studies of the “anthrome” – the human-dominated, or anthropogenic biome – are poised […] Read More »... Read more »

Publishing Open Access is Good for Your Academic Reputation

by Hadas Shema in Information Culture

In the academic world, reputation is the currency of choice. "Reputation," of course, is a very loose term and can include anything from publishing in high-impact journals to being a good advisor to your students. How does OA contribute to your academic reputation?The first significant scholarly repository, arXiv.org, was started by high-energy physicists, but quickly expanded to include other scientific disciplines. Today, archiving in arXiv.org is practically a necessity for physicists. Archiv........ Read more »

Of Fossil Ghosts and Hippos Past

by Laelaps in Laelaps

To call hippos “charming” may seem a bit of a stretch, but they are most certainly among the classic charismatic megafauna of the African continent. In the wake of the end-Pleistocene ecological catastrophe – during which waves of extinction denuded the planet of many strange, large-bodied mammals from woolly mammoths to wombats the size of [...]...

Bacterial cell division and membrane potential

by Lab Rat in Lab Rat

Bacterial cell division is usually quite a regular business. As I mentioned previously, not all bacteria use the regular FtsZ ring method of dividing, but for those that do division is mostly a matter of lining the right proteins along the middle of the bacteria, and then contracting a little ring of protein (FtsZ) around the centre of the bacteria to split the one cell into two cells.Many of the more critical proteins in the process are membrane-bound, in particular the Min proteins, which in E........

Growing big brains

by Zen Faulkes in NeuroDojo

We think that good environments make for good brains, particularly when people are young. Parents have been known to obsess a little about whether their kid is getting the right kind of experiences.


If this is true, this guy must have read a looooooot of books.


Joking aside, we normally think about early experiences as influencing subtle things about the brain. Those early experiences might give you some extra connections, tweak a little wiring here and there. But you wouldn't expect someon........ Read more »

Immunological standoff

by iayork in Mystery Rays from Outer Space

TRegs infiltrate into a tumor There’s increasing evidence supporting the notion that tumors are often not rejected by the immune system because regulatory T cells actively block the immune response to the tumor cells. 1 That means that within the tumor, two branches of the immune response are fighting it out. If the TRegs win, [...]... Read more »

Sons of the conquerers: the story of India?

by Razib Khan in Gene Expression


The past ten years has obviously been very active in the area of human genomics, but in the domain of South Asian genetic relationships in a world wide context it has seen veritable revolutions and counter-revolutions. The final outlines are still to be determined. In the mid-1990s the conventional wisdom was that South Asians were [...]... Read more »

better protein pharmacokinetics with a tail

by 96well in Reportergene

A combined protein/polymer-engineering approach prolongs protein circulation and enhance drug accumulation in tumours.
Consider insulin and you will have no doubts that a protein could be a drug. As proteins are coded by a corresponding DNA, the application of recombinant DNA has been largely exploited in clinics to provide patients with therapeutic 'recombinant' proteins. Among the advantages of owing a potential pharmacon on a plasmid, and growing such a marketable molecule in cell cultures, i........ Read more »

AquAdvantage update

by Anastasia Bodnar in Biofortified

In Risk assessment and mitigation of AquAdvantage salmon I discussed exactly what Aqua Bounty was asking permission from the FDA to do, as well as the environmental, animal welfare, and human health concerns associated with the AquAvantage fish in comparison to non-transgenic farmed salmon. The Center for Food Safety has a “new” document to bring to the discussion: an opinion (pdf) written by the National Marine Fisheries Service regarding a U.S. Army Corps of Engineers proposal a........

What do we do with forecasts of the future?

by Noam Ross in Noam Ross

Via Garry Peterson  I discovered this post by Simon Donner about forecasts of this year's massive coral bleaching event in the Carribbean.
Donner and colleagues published a paper in PNAS in 2007 in which they calculated that heat waves that cause massive coral bleaching, like a previous event in 2005, had gone from being 1-in-1000-year events to a probability of once every 10-50 years during the 1990s, and by the 2030s will occur every 1-2 years. This year's event, says Donner, i........ Read more »

Big data

by Michelle Greene in NeurRealism

It took 13 years to crunch through the 3 billion base pairs that make up the human genome. These data have been violating our assumptions ever since. My introductory biology textbook, published in 1996, speculates that there might be up to 100,000 genes in the genome. It turns out there are a lot less: about 20,000-30,000 by more recent estimates. The Human Genome Project sequenced only a few individuals, and combined all into one genome. However, many of the big questions we have about genetics........ Read more »

Oddest photo accompanying 1000 Genomes news

by Mary in OpenHelix

Right now on the Science section of The Guardian, I find this [photo of bikini clad concert goer?]:

Er, what?
OK–but the real news is in Nature today. With an appropriate cover image.

Anyway, I’ve just barely had a chance to look over the paper. I often find the supplemental info is what I need (methods, software, etc), and that’s almost another hundred pages for one of them. So I don’t have any real conclusions yet.  Some of it was familiar to folks who may have been using the 1........ Read more »

But did you correct your results using a dead salmon?

by Iddo Friedberg in Byte Size Biology

fMRI tests are very popular. Why should they not be? Take someone, stick them in an MRI, show them a picture of their mother-in-law, see which bits of their brain light up (get more blood, hence are more active) and voila! You’re in the New York Times science supplement under the title “Scientists discover brain region responsible for unmitigated rage.” (Any resemblance to any actual mother-in-law, living or dead, is purely coincidental.) fMRI is a great tool for mapping cogni........

The grand diversity of marine phytoplankton species: focusing from space

by Hannah Waters in Sleeping with the Fishes

In a recent email exchange with a (skeptically) wonderful blogger about why we are interested in what we are and where past/current biases lie, I wrote that I “grew up wanting to look at the planet from space.”  This is true in multiple senses: my drive to seek patterns in collected studies and data, and also my interest in large-scale ecology generally. But, of course, we can actually look at the planet from space!  And collect data at the same time!  Via the wonder of SATELLIT........ Read more »

Where did all these primates come from? – Fossil teeth may hint at an Asian origin for anthropoid primates

by Laelaps in Laelaps

Where did anthropoid primates come from? This question has not been an easy one to answer. Since the early days of paleontology various experts have proposed a slew of scenarios for the origins of the primate group which today contains monkeys and apes (including us), with different experts favoring various combination of places, times, and [...]...

Mt. Moult

by Journal Watch Online in Journal Watch Online

Some people climb tall mountains because they are there. In Nicaragua, a tiny hummingbird apparently heads to the summit to grow a new crop of feathers. The unusual vertical moulting migration highlights the challenge of protecting species that may travel far and high to survive.
The blue-tailed hummingbird (Amazilia cyanura) is a common but little-studied […] Read More »... Read more »

Functional selectivity: Nature's Bach concerto

by The Curious Wavefunction in The Curious Wavefunction

One of the great things about Bach’s organ music is how changes of a single note in a whole pattern can have rather dramatic effects on the sound. A unique and potentially very important similar phenomenon has been discovered recently in the area of GPCR research.The understanding of the basic process by which GPCRs transmit signals from the cell exterior to the interior has seen remarkable advances in the last three decades, but much still remains to be deciphered. Our knowledge of signaling ........ Read more »

The evolution of novelty through subtle tinkering

by Lucas in thoughtomics







The genealogies of European royalty are genuinely terrifying in their complexity. No matter which history book you open, someone is always marrying some cousin of the third degree. To give you an idea: there are at least 4,010 different lines of descent from William the Conqueror to Prince William. Go figure.
Protein families might rival European [...]... Read more »
