Darwin's contributions and why this matters for Mexico's conifers

by Claire Williams in Conifer Reproductive Biology

For International Darwin Day, February 12. Darwin's birthday inspired an elegant treatise by UNAM professor Antonio Lazcano, published in Science back in 2005. His article traces the cultural, social and science history roots behind widespread acceptance of Darwin's ideas in Mexico. This careful analysis is worthwhile reading, particularly for those working in the USA.... Read more »

Dance Macabre: Will 14th Century Remains Reveal the Pandemic Secrets of the Black Death?

by Sara Klink in Promega Connections

Another group of researchers decided to further analyze the causative agent of the Black Plague by enriching for and sequencing one of the extrachromasomal plasmids present in the bacterial genome: the 9.6kb virulence-associated pPCP1 plasmid.

The recently published research in the Proceedings of the National Association of Science USA chose to use samples from East Smithfield (ES) cemetery in London, England, a burial ground that was established during the medieval Black Death pandemic of 13........ Read more »

Bisexuality is natural for women

by United Academics in United Academics

Researchers at the Boise State University have found that most women are bisexual by nature. Also, they discovered that these bisexual feelings increase with age. During this study, 484 heterosexual women were surveyed. 60 percent of them said to be sexually attracted to other women, 45 percent had already kissed with a woman en about half of the participants had fantasized about it....

Communication as a network problem

by Becky in It Takes 30

I recently gave a short talk to a group of post-docs who had organized their own mini-symposium and workshop as a way of bringing the Harvard post-doc community in systems biology together. Those of you who haven’t worked in the Boston area may be surprised that we need special events to bring together a community that is separated by only ~4 miles, but in fact the trip from Harvard’s main campus in Cambridge to Harvard Medical School in Boston is a frustrating and lengthy one.

Three Top Redox-Reagents for preventing protein oxidation

by Vicky Doronina in Protein Solubility Blog

Intact cells contain enzymatic and non-enzymatic systems, which counteract amino acid oxidation by reactive oxygen species from the air and chemical reactions and return them into unmodified state. However, after you break the cells, the anti-oxidation systems are gone and you have to supply excess of external antioxidants. In general, the concentration of the reducing agent should be more than your protein concentration. The good old dithiothreitol (DTT) or β-mercaptoethanol (BME) are no........ Read more »

I WILL FEAR NO EVIL: THE FIRST HEAD TRANSPLANT ON HUMAN

by Eugenio Maria Battaglia in Science to Grok

In 2008, doctor Sergio Canavero, an italian neurosurgeon based in Turin, IT, have awakened a 20 years old lady from a permanent post-traumatic vegetative state, by means of a bifocal extradural cortical electro-stimulation. Today, while Science still find it hard to explain consciousness and embodied cognition – the world-class neurosurgeon made a shock announcement: “I’m ready for the first head transplant on a man.”

In the manuscript published on Surgical Neurology I........ Read more »

IS THIS A BANANA I SEE BEFORE ME? SEEING COLOURS THAT AREN’T THERE

by A Giffen in Antisense Science

We all know that bananas are yellow, strawberries are red and oranges are…well orange. But what about a black and white banana? Or a grayscale green bean? Well it turns out our brain still processes these images in the colour we think they should be in.Banana

In a study carried out earlier this year, neuroscientists showed there was a link between our memories, our knowledge of object colour and the way neuronal networks in the brain perceive the object when presented in black and whit........ Read more »

Recent reports on BHD and skin symptoms – misdiagnosis and new manifestations

by Joana Guedes in BHD Research Blog

Patients with Birt-Hogg-Dubé (BHD) syndrome usually develop benign hair follicle tumours (BHFTs) which appear as multiple whitish papules developing primarily on the face, neck and torso (Menko et al., 2009). BHFTs such as fibrofolliculomas and trichodiscomas (skin-coloured tumours occurring on the upper body) can be associated with various genetic conditions and their histology is often key to differential diagnosis. The morphology and histology of various BHFTs is discussed in a recent ........ Read more »

PD-L1 expression associates with non-inactivated VHL ccRCC

by Joana Guedes in BHD Research Blog

The loss of the of the tumor suppressor gene VHL and the subsequent deregulation of VHL/HIF/VEGF signalling are known to play a role in development of clear cell renal cell carcinoma (ccRCC). Renal tumours associated with BHD syndrome are histologically diverse and include a percentage of ccRCC (Pavlovich et al., 2002). Anti-angiogenic therapies targeting the VHL/HIF/VEGF pathway have emerged in past years (Rini et al., 2006) but the development of resistance to these therapeutic agents is leadi........ Read more »
