New Stem Cells on the Block. A a colony of human ESCs (upper portion) extracted from a blastocyst generated by SCNTCELL/TACHIBANA ET AL.Researchers have for the first time produced human embryonic stem cells (hESCs) using somatic nuclear transfer (SCNT), a method in which the nucleus of a donor cell—in this case a skin cell or fibroblast—is transferred to an egg cell whose own nucleus has been removed. The work, published today (May 14) in Cell, opens up the possibility of an alternative source of patient-specific stem cells to help scientists understand disease and develop personalized cell-based therapies.
What’s more, hESCs produced via nuclear transfer (NT-hESCs) may not have the genetic and epigenetic abnormalities found in induced pluripotent stem cells (iPSCs), made by adding key genes to reprogram adult cells. “I think it is a beautiful piece of work,” said George Daley of Boston Children’s Hospital and the Harvard Stem Cell Institute, who was not involved in the research, in an email to The Scientist.

Flight of the Dodo. 19-Year-Old Student Develops Ocean Cleanup Array That Could Remove 7,250,000 Tons Of Plastic From the World's Oceans. 19-year-old Boyan Slat has unveiled plans to create an Ocean Cleanup Array that could remove 7,250,000 tons of plastic waste from the world’s oceans.
The device consists of an anchored network of floating booms and processing platforms that could be dispatched to garbage patches around the world. Instead of moving through the ocean, the array would span the radius of a garbage patch, acting as a giant funnel. The angle of the booms would force plastic in the direction of the platforms, where it would be separated from plankton, filtered and stored for recycling. At school, Boyan Slat launched a project that analyzed the size and amount of plastic particles in the ocean’s garbage patches. Slat went on to found The Ocean Cleanup Foundation, a non-profit organization which is responsible for the development of his proposed technologies.
It is estimated that the clean-up process would take about five years, and it could greatly increase awareness about the world’s plastic garbage patches. Immune System Kills Cancer. Motto: Happy Easter! Let this joy of Easter fill up our heart, Today and the whole year ahead. May you live a long life and May Easter come in your life 100 times. Thanks! According to the medicine researches, the cells cancer is the result of the spindle pole body misorientation. "What is it that breathes fire into the equations and makes a universe for them to describe? Henry Schaefer - "The significance and joy in my science comes in the occasional moments of discovering something new and saying to myself, 'So that's how God did it!
' Moreover, in addition, philosophical one and biblical one: "The bad part is that people of medicine dealing with the body more than soul. " "Foolish people! In medicine "sternum" is called "double-edged sword". In Hellenic, "xiphos" means the "pinpoint". Bible, Paul, Hebrew 4.12: "The word of God is alive and active, sharper than any double-edged sword.
Bible, Genesis 9.4 - "I forbid this because the life is in the blood. " see also: First Love Child of Human, Neanderthal Found. The skeletal remains of an individual living in northern Italy 40,000-30,000 years ago are believed to be that of a human/Neanderthal hybrid, according to a paper in PLoS ONE. If further analysis proves the theory correct, the remains belonged to the first known such hybrid, providing direct evidence that humans and Neanderthals interbred. Prior genetic research determined the DNA of people with European and Asian ancestry is 1 to 4 percent Neanderthal.
The present study focuses on the individual’s jaw, which was unearthed at a rock-shelter called Riparo di Mezzena in the Monti Lessini region of Italy. Both Neanderthals and modern humans inhabited Europe at the time. PHOTOS: Faces of Our Ancestors Condemi is the CNRS research director at the University of Ai-Marseille.

Tasmanian Tiger chosen for 'de-extinction' The Tasmanian Tiger is the only marsupial to make a list of the top 10 animals scientists would bring back from extinction.
While there are still claimed sightings of the Thylacine, the last known Tasmanian Tiger died in Hobart Zoo in 1936 and it was declared extinct in 1986. But now scientists think that it is of such value it should be included in a list of animals that should be considered for bringing back from extinction using DNA. Yahoo! Business Insider reported that researchers discounted dinosaurs - saying their DNA was too degraded. They established criteria by which animals would be chosen: • Are the species desirable — do they hold an important ecological function or are they beloved by humans? • Are the species practical choices — do we have access to tissue that could give us good quality DNA samples or germ cells to reproduce the species?
