Remarkable similarity between embryonic and induced pluripotent stem cells - a UW proteomic study

in medicine, biology, omics

In a new study published in Nature Methods, researchers at the University of Wisconsin-Madison report the first full measurement of the proteins made by human embryonic and induced pluripotent stem cells.

Brainy Managers – Study shows managerial experience linked to hippocampus size

in biology

Managing other people at work triggers structural changes in the brain, protecting its memory and learning center well into old age.

Stem Cells Generated From Endangered Species

in biology

Scripps scientists converted normal skin cells from two endangered species to induced pluripotent stem cells, creating  the first stem cells from endangered species.

Hair Growth Signal Dictated by Fat Cells - Hope for the Bald

in medicine, biology

Can baldness be cured?  Yale researchers say that the trick is in getting fat cell (adipocyte) precursors under the skin to talk to stem cells at the base of the hair follicles.  The discovery of the source of signals that trigger hair growth may lead to new treatments for baldness.

Bioethanol from Cellulose - Plant Matter to Replace Oil as a Fuel Source

in technology, biology

Researchers identified the molecular mechanism behind an enzyme found in fungi which can degrade the cellulose chains of plant cell walls to release shorter sugars for biofuels.

Matching Images of Brain Activity with Complex Thought

in technology, medicine, biology

Can you get a text output of your thoughts? Princeton scientists show that it is possible to generate text about the mental content reflected in brain images. Recent work has shown that it is possible to take brain images acquired during viewing of a scene and reconstruct an approximation of the scene from those images. 

Omega-3 and Omega-6 Fatty Acids in the Diet Can Alter Offspring Sex Ratio - Grain for Girls, Fish for Boys?

in environment, medicine, biology

Can maternal diet influence offspring sex ratio?  According to a research report from New South Wales (Australia) Department of Primary Industries, ratio of omega-6 to omega-3 fatty acids in the diet of mother has a profound effect on offspring sex ratio. 

Sutureless Method for Joining Blood Vessels - A Surgical Revolution?

in technology, medicine, biology

A Stanford University surgical research team used a poloxamer gel and bioadhesive rather than a needle and thread to join together blood vessels, a procedure called vascular anastomosis.  An anastomosis is the technique by which two hollow body structures, such as blood vessels, are joined together.
