I WILL FEAR NO EVIL: the first head transplant on human
by Eugenio Maria Battaglia in Semanto.me
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 »

Quantum-Dot Microscopy Method Allows to Improve Solar Cells
by dailyfusion in The Daily Fusion
Researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture—cathodoluminescence—to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size....

Psychology At the Movies: Essentialist Musings in Man of Steel
by Psych Your Mind in Psych Your Mind
www.imdb.com
Yesterday, my spouse and I dropped our newborn daughter off with Grandma and then popped over to the local theater to see this summer's much anticipated comic-book blockbuster Man of Steel. By any standard, Man of Steel is exceptionally light when it comes to philosophical musings: The plot is predictably linear--good guys fight bad guys who are trying to kill them. At first glance, it may seem like a stretch to write an entire blog entry (for a psychology blog) about the fil........ Read more »

The study of how cells move in development is not just about development. Understanding cell migration can also help researchers understand how tumors spread and invade other tissues. So, the next time you see someone roll their eyes at your fruit fly egg chambers (or worm vulva, or culture dishes), take pity at their ignorance and explain to them how they should thank you instead.The movement of cells during development drives the shape changes and organization of an embryo.

Nanog protein promotes the growth of cancer stem cells in head and neck cancer
by beredim in Stem Cells Freak
A new study led by researchers at The Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James) has identified a biochemical pathway in cancer stem cells that is essential for promoting head and neck cancer.The study shows that a protein called Nanog, which is normally active in embryonic stem cells, promotes the growth of cancer stem cells in head and neck cancer. The findings provide information essential for de........ Read more »

Life After Recovery for Men with Eating Disorders
by Andrea in Science of Eating Disorders
While there is growing recognition that (surprise, surprise!) men are not immune to eating disorders, men are still underrepresented in the literature about eating disorders. We know comparatively little about what it is like to be a man with an eating disorder, and less still about recovery and life after recovery for these individuals. Recently, Björk, Wallin, & Pettersen (2012) conducted a qualitative study that asked men who had been diagnosed with an eating disorder and completed........ Read more »

Even ‘environmentally protective’ levels of pesticide devastate insect biodiversity
by Anouk Vleugels in United Academics
Pesticide levels considered environmentally friendly in Europe and Australia are, in fact, having a devastating effect on invertebrate insect biodiversity in nearby creeks and streams, a new study has found, showing the need for an urgent overhaul of the way pesticide risk is assessed. Water-dwelling invertebrates like worms, snails, crustaceans, mites and insects play a crucial role in regional ecosystems because they provide food for fish, birds and platypuses.... Read more »

"Undruggable" cancers may by druggable
by beredim in Stem Cells Freak
Harvard Stem Cell Institute (HSCI) researchers have identified in the most aggressive forms of cancer a gene known to regulate embryonic stem cell self-renewal, beginning a creative search for a drug that can block its activity.The gene, SALL4, gives stem cells their ability to continue dividing as stem cells rather than becoming mature cells. Typically, cells only express SALL4 during embryonic development, but the gene is re-expressed in nearly all cases of acute myeloid leukemia and 10 to 30 ........ Read more »

NYSCF researchers generate beta cells from MODY patients
by beredim in Stem Cells Freak
A team from the New York Stem Cell Foundation (NYSCF) Research Institute and the Naomi Berrie Diabetes Centre of Columbia University has generated patient-specific beta cells, or insulin-producing cells, that accurately reflect the features of maturity-onset diabetes of the young (MODY).The researchers used skin cells of MODY patients to produce induced pluripotent stem (iPS) cells, from which they then made beta cells. Transplanted into a mouse, the stem cell-derived beta cells secreted insulin........ Read more »

Explainer: Why Do Women Menstruate?
by Dyani Lewis in United Academics
For half the population, it comes three to five days each month, 12 months each year, for 40 years of our lives. Menstruation can be debilitating, relieving, disappointing, or simply an inconvenient fact of life.
But why do humans menstruate, when most animals don’t? When you shake the tree of life, you find that only a handful of mammals aside from us – primates, a small number of bat species, and the elephant shrew – have opted for the monthly bleed.... Read more »

The Hazards of Debating Race and Inequality
by Eric Horowitz in peer-reviewed by my neurons
Imagine there is a certain advantaged group of people that supports a policy that harms a disadvantaged group, and you believe there are hints of racial or ethnic bias underlying their position. Even if the advantaged group doesn’t literally believe that the disadvantaged group is less deserving, it’s impossible to view their insensitivity to the [...]... Read more »

It's Fun to Play with the Y- and C- Graft
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: While both the Y-graft and C-graft effectively stabilized the patellofemoral joint, the patients who received the Y-graft had significantly better subjective outcome scores than the patients who received the C-graft.
Patients who endure a patellofemoral dislocation are often plagued with patellofemoral instability and frequent re-injury. While multiple methods of patellar fixation exist, a gold-standard does not. Therefore, Kang and colleagues performed a randomized trial t........ Read more »
