Scientists succeed in cloning human embryos from eggs matured in the lab

...tes and non-autologous transfer via a conventional method of nuclear transfer. "Our final goal is to use human therapeutic cloning for infertility treatment by creating artificial eggs and sperm for patients who are infertile because of absence or premature loss of eggs or sperm. We would do this by isolat...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...icient and work only under acidic conductions. Our method can be used over a much broader pH range, including wastewater pH conditions." Fe-TAMLs already have shown promise in killing a simulant of a biological warfare agent (anthrax), reducing fuel pollutants, treating pulp and paper processing byproduct...

Newly discovered genetic disease sheds light on body's water balance

...diatric endocrinologist Walter Miller, MD, using a method to determine cAMP levels in cells by using a luciferase plasmid that responds to cAMP. Luciferase is the substance that lights up in fireflies. Feldman showed that wild-type cells contain low levels of light from luciferase -- and thus low levels of...

Major advance made on DNA structure

... understand. Until now, there has been no reliable method to identify DNA structure from sequence, and learn more about its effects on biological function. In their studies, the OSU scientists used X-ray examination of crystalline DNA to reconstruct exactly what the DNA looks like at the atomic level. By d...

Scientists turn tobacco against cancer

...s. The plants promise to provide a cheaper, faster method of producing anticancer antibodies, raising hopes that the technology can one day be used in humans. Scientists, led by Hilary Koprowski, M.D., professor of microbiology and immunology and director of the Biotechnology Foundation Laboratories and th...

Novel plague virulence factor identified

"We did in fact show that as Y. pestis lacking the hmsHFRS operon accumulated in the intestine causing a persistent and lethal infection." The researchers then screened a library of almost 1,000 Y. p...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...ght on why the placebo effect occurs. The imaging method used in the study involves tiny doses of a medicine called carfentanil that is attached to a short-lived radioactive form of carbon, which releases subatomic particles known as positrons. These positrons are detected with the PET scanner, which acts ...

Researchers devise new technique for creating human stem cells

...rnative to somatic cell nuclear transfer (SCNT), a method that is currently used to produce human stem cells. SCNT involves transferring the nuclei of adult cells, called somatic cells, into oocytes in which scientists have removed the nuclei. The researchers said that -- while the technique might one day ...

New research could help us deliver genes for new bone formation

...cells to initiate the bone formation process. This method of gene delivery could provide significant healthcare benefits as trauma, degenerative disease and bone loss with old age all lead to patients needing orthopaedic procedures that require new bone. Professor Oreffo added "It is important that we expl...
