Tools of Paleomicrobiology

by Michelle Ziegler in Contagions

Studying ancient microbes requires creativity. Contamination and  preservation are the primary problems, dealing with limited and degraded tissues. We don’t find corpses in permafrost every day! Most of the time tissue is confined to bones and mummies kept in a wide variety of environments. This post will review some of the major tools I have [...]... Read more »

It's Silent, But is it Deadly?

by The Defective Brain in The Defective Brain

Last February, an international controversy descended over the landlocked country of Malawi. The cause of this was a new bill about to be put forward that centred on the maintenance of clear air in public places.
Any person who vitiates the atmosphere in any place so as to make it noxious to the public to the health of persons in general dwelling or carrying on business in the neighbourhood or passing along a public way shall be guilty of a misdemeanour... Read more »

Mole Crickets (Orthoptera: Gryllotalpidae)

by Marc in Teaching Biology

Mole crickets (Gryllotalpidae) are cosmopolitan (except the poles), 3.2 – 3.5 cm (average, they can be larger than 5 cm!) relatives of crickets (suborder Ensifera, superfamily Grylloidea), named after the mole, since they are both animals that are highly-dependent on burrowing, and they kind of resemble each other (see drawing of Gryllotalpa hexadactyle to the [...]...

Botanists vote to allow online publication of new taxa

by Ryan Kitko in Cunabulum

The excitement (and nervous uncertainty) is tangible on botanical taxonomy e-mail lists with the recent news that the nomenclature section of the International Botanical Congress, the governing body of the rules on how we describe new species and other taxa, voted at this year's Melbourne conference to drop the requirement that all new taxa must be described in print publications. If the rule is adopted by the whole Congress, we'll soon see new taxa being published in online-only peer-........ Read more »

Asthma, placebo, and how not to kill your patients

by PalMD in White Coat Underground

A number of years ago I was walking along Lake Michigan with a friend (a fellow medical resident) when she turned to me and said, "are you wheezing?  Do you have asthma?"  I had always been physically active and assumed my breathlessness while walking down the trail was due to the thirty extra pounds of [...]...

Why bees might save the world (a.k.a. The buzz about bees)

by NerdyOne in Try Nerdy

If you weren’t yet aware, bees have been kind of a big deal in the science world lately. I’m not making this up: they can learn to recognize human faces, they can monitor air quality, and, oh yeah, they can solve problems faster than supercomputers.

Though this blog has already featured insects more than I would have imagined (i.e. at all), this post is about something I really feel the need to share. Because, every so often, I come across something for which the research is so ov........ Read more »

Birds Display Their Animal Magnetism

We condemn more when we think we're being watched

by Tom Rees in Epiphenom

In a nice new study, Pierrick Bourrat (at the University of Sydney) and colleagues have shown that people are more likely to judge others severely when they are given even subtle hints of being watched.

The set-up was simple. The subjects (recruited from the Campus Universitaire de Jussieu in Paris) had to read a tale of a minor misdeed - finding a wallet in the street and keeping the cash, or falsifying a resume - and then judge how morally wrong it was.

The twist was that half the subjects h........ Read more »

HLA matching and minority transplants

by Cristy at Living Donor 101 in Living Donors Are People Too

In 2003, the US kidney allocation system was loosened to eliminate HLA-B similarity. (Improvement in anti-rejection meds made this possible) During the first six years after the change, total number of deceased donor transplants rose 23% in comparison to the six years prior to the change, including 40% increase for minorities. There appeared to be no adverse effect on graft survival after two years. And that part nags at me a bit. They tracked for six years, and only looked at the two year graf........ Read more »

Beyond corn ethanol: biofuels in the U.S. from switchgrass and miscanthus

by Paul Spraycar in Agriculture & Land Use Forum

If the measure of a story’s importance is whether it makes it into the New York Times, then a new biofuels study in Frontiers in Ecology and the Environment deserves our attention.
The study looks at the impending transition of the U.S. biofuel industry from one based on corn to one using ‘second-generation’ feedstocks. Specifically, the study presents a hypothetical scenario in which all corn-based ethanol is replaced with switchgrass and miscanthus, two promising perennial c........ Read more »

Flexing the Muscle that is Self-Control

by Psych Your Mind in Psych Your Mind



source
College was a busy time for me and by extension a trying period for my roommate Vanessa. Unlike the average 19 year old, Vanessa had assumed such adult-like habits as washing dishes directly after eating a meal, making regular trips to take out the trash, and refusing to live with scum and filth in general (God forbid). These healthy habits were by no means my own. I was just learning how to balance the demands of my two priorities: a heavy workload at NYU and a debaucherous social life........ Read more »

Coaxing more food from less land

by Tim De Chant in Per Square Mile

It’s easy to forget amidst the concern over sprawl that agriculture is still the dominant human impact on the land. Perhaps that’s because it’s easy to rationalize the consequences of agriculture’s land use—it feeds us, after all. But that shouldn’t dissuade us from finding ways to improve farm efficiency. Global population growth shows no signs of [...]... Read more »

Earliest Occupation of Crete May Date to 125,000 Years Ago

by Kristina Killgrove in Powered By Osteons

A recently published article in the Journal of Quaternary Science by Strasser and colleagues suggests new dates for stone tools discovered on the island of Crete.  Namely, the artifacts are associated with geological strata that date to the late Middle Pleistocene or early Late Pleistocene, meaning a terminus ante quem of 125,000 years ago.

An archaeological survey in the Plakias area of Crete between 2008-09 uncovered nine sites and over 400 artifacts.  The stone tools discovered wer........ Read more »

It’s not what you know…

It’s not what you know, but who you know. It is something of a cliché, but in a world where the social context of knowledge is becoming increasingly important.

Chest X-rays: Learning forbearance

by Nancy Fliesler in Vector, a Boston Children's Hospital blog

In emergency situations involving children, it’s tempting for doctors to do everything possible to get information, especially when anxious parents are at hand. Unfortunately, that can mean a lot of unnecessary imaging and radiation exposure, and sometimes fruitless exploratory surgery.

This has spurred a search for biomarkers that can reliably make or rule out a diagnosis, as in appendicitis, and the creation of decision rules about the need for imaging, as in minor head trauma and blu........ Read more »

Bachmann, Migraine and Work Impairment

There has been recent interest in the issue of migraine and work impairment related to Michele Bachmann, a candidate for the Republican Party in the 2012 presidential election.  Bachmann has acknowledged that she suffers from migraine headaches.  The attending physician to Congress released a letter stating representative Bachmann's migraine headaches are infrequent, related to known triggers and managed on as needed medications including sumatriptan and ondansetron.This issue prompts ........

When virus's and bacteria unite!

by Lab Rat in Lab Rat Blog

Illnesses have a tendency to clump together. An attack of the flu can bring on bacterial lung infections; in the USA almost half of all cases of bacterial sepsis occur following viral infections in the lungs. This is a problem at the best of times as it means that patients spend longer in hospitals, but in times of a viral pandemic it becomes incredibly deadly.... Read more »

Linguistic diversity and traffic accidents

by Sean Roberts in A Replicated Typo 2.0

I wondered if statistics about population movement would correlate with linguistic diversity. I found that number of traffic fatalities are a pretty good predictor. What's going on?... Read more »
