Scientists have made a major breakthrough in the study of embryonic development and how it can be impacted by external factors such as climate...

Researchers discover possible origin of neuroblastoma in the adrenal glands Neuroblastoma is a childhood cancer, most commonly affecting children aged between 2 -3 and can be fatal. Since the tumor cells resemble certain cells in the adrenal glands, a joint research group from MedUni Viennas Center for Brain Research and the Swedish Karolinska Institute investigated the cellular origin of these cells and sympathetic neurons during the embryonic development of human adrenal glands. During the co...

MIT biologists find cell extrusion, a process that helps organisms eliminated unneeded cells, is triggered when cells can’t replicate their DNA during cell division. In humans, extrusion may serve as a way for the body to eliminate cancerous or precancerous cells.

Abstract Many of the most important resolution improvements in optical microscopy techniques are based on the reduction of scattering effects. The main benefit of polarimetry-based imaging to this end is the discrimination between scattering phenomena originating from complex systems and the experimental noise. The determination of the coherency matrix elements from the experimental Mueller matrix can take advantage of scattering measurements to obtain additional information on the structural o...

Researchers identify long-sought enzyme that prevents cancer Researchers have found a long-sought enzyme that prevents cancer by enabling the breakdown of proteins that drive cell growth, and that causes cancer when disabled. Publishing online in Nature on April 14, the new study revolves around the ability of each human cell to divide in two, with this process repeating itself until a single cell (the fertilized egg) becomes a body with trillions of cells. For each division, a cell must follo...

Researchers uncover how cells control the physical state of embryonic tissues By Sonia Fernandez Santa Barbara, CA In the earliest stage of life,...

Weizmann Institute of Science To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought grail in the field of embryonic development for nearly 100 years. Prof. Jacob Hanna of the Weizmann Institute of Science and his group have now accomplished this feat. The method they created for growing mouse embryos outside the womb during t...

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers at the University of Illinois Chicago.

Richard Feynman, one of the most respected physicists of the twentieth century, said "What I cannot create, I do not understand". Not surprisingly, many physicists and mathematicians have observed fundamental biological processes with the aim of precisely identifying the minimum ingredients that could generate them. One such example are the patterns of nature observed by Alan Turing.
