12:00 PM | They Can See The Blood Running Through You
Biology concepts- thermosensors, TRPV1, hematophagy, taste sense, alternate splicing, echolocation All three species of vampire bat live in Central to South America, the common vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat (Diaemus youngi).Any idea what the picture to the left shows? A hint – this may be the most sophisticated piece of machinery ever devised by nature. Together with the organism to which it’s […]

8:33 AM | Silence ENO2! More epigenetics and autism
The paper by Yu Wang and colleagues [1] (open-access here) concluded that: "reduced ENO2 expression may be a biomarker for a subset of autistic children" following their genome-wide methylation study of autism. For those who've picked up the word 'methylation' in that first sentence, this is yet another sign that epigenetics - the science of changes to gene function not entailing structural genomic changes - is starting to impact on autism research.Silentio! @ Wikipedia Based on an […]

9:58 PM | What a difference a shrew makes
Last year, I wrote an article about how we used pine marten (Martes martes) scats or faeces to detect the DNA of small mammals that the pine marten had been feeding on. These small mammals included the wood mouse (Apodemus … Continue reading →

2:51 PM | Is it okay to eat fish if they don’t have any feelings? (Updated)
When a scientific paper begins its list of keywords with “fish cognition”, you know you’re in for a good read. Culum Brown is tired of people eating fish, and he’s not going to take it anymore. Fish, he says, are smarter than you think. We need to cast off our view of them as dumb slimy creatures and […]

1:18 AM | Getting more bang for your photonic buck: nano-engineered quantum dots provide avenue for improved solar cell efficiency
New research out of Los Alamos National Laboratory, published in Nature Communications last week, has demonstrated a new material tailored at the nanoscale that provides great hope for use in next-generation, multiexciton solar cells.  Multiexciton photovoltaics have been an enticing … Continue reading →
