  • State Department report finds Iran is top state sponsor of terror

    The State Department on Thursday released its annual report on global terrorist activity, listing Iran as the top state sponsor of terrorism and labeling ISIS "the greatest threat globally." The report also includes statistics on terrorist activity worldwide, and said 11,774 terrorist attacks in 92 countries occurred in 2015. Iran's designation and continued sponsoring of terrorism is bound to fuel criticism of the Iran nuclear deal. Critics of the deal have charged that the removal of economic sanctions would allow Iran to increase its support of terror groups.

    The scientists discovered that the ceramide-1 phosphate transport protein (CPTP) regulates levels of biologically active lipids, which are molecules such as fatty acids that often play a role in cell signaling. They found that CPTP's main function is to transport ceramide-1-phosphate (C1P), a lipid that helps regulate cell growth, survival, migration and inflammation. Specifically, C1P increases the production of pro-inflammatory eicosanoids ‚Äď powerful signaling molecules that contribute to chronic inflammation in diseases such as cancer, asthma, atherosclerosis and thrombosis ‚Äď and the discovery of CPTP sheds a light on the cellular mechanisms that contribute to these diseases.

    Researchers from Canada, France, Germany and the United States reporting in the journal Cell have found a new ground-breaking way of killing cancer cells.

Contrastingly, a new potential treatment does not damage healthy cells and could also be used to treat a wide variety of different cancers. "Cancer cells grow and divide much more rapidly than normal cells, meaning they have a much higher demand for and are often starved of, nutrients and oxygen," explained study co-author...

    Elect Obama, Get Embryonic Stem CellsMarch 8, 2009 ó President Obama is about to fulfill one of his campaign promises: lifting restrictions on creating new embryonic stem cell lines (see Fox News).† The question now is, are they really needed?† They have yet to show any successes, while adult stem cells are enjoying an accelerating boom of amazing discoveries that could provide hope for some of mankindís worst disorders. (Note: ESC = embryonic stem cells, ASC = adult stem cells). Muscular dystrophy:† Children and adults plagued by the muscle-wasting malady of muscular dystrophy may now have hope thanks to...

    Scientists have overcome a major barrier to human use. Monday, March 02, 2009 By Emily Singer In 2006, Shinya Yamanaka and his colleagues at Kyoto University in Japan reported that they could reprogram mouse skin cells to an embryonic-like state by adding four genes, since dubbed the Yamanaka factors. These cells, called induced pluripotent cells, can be transformed into different types of cells and tissues, and hold promise for studying disease and developing cell replacement therapies. However, scientists inserted the genes using viruses, making the cells unsuitable for human use. Now, for the first time, British and Canadian scientists have...

    Right Side News' first issue of an eight part series written by Kathy Shaidle. excerpt: Today many Americans are either blissfully ignorant of, or simply indifferent to, the slow, incremental growth of radical Islam in their midst. We sometimes hear about terrorist cells or suspicious Muslim "compounds" on the news. However, these stories represent merely the tip of an Islamic iceberg that could very well doom America. Not today or tomorrow. But in our lifetimes? That is a real possibility. And don't shrug off Islam as "just another religion." Muslim sharia law deems women to be inferior to men, and...

    Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper* by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level. Applying modern engineering design tools to one of the basic units of life, they argue that artificial cells could be built that not only replicate the electrical behavior of electric eel cells but in fact improve on them. Artificial versions of the eelís electricity generating cells could be developed as a power source for medical implants and other tiny devices, they say. The...

    Scientists have stopped the ageing process in an entire organ for the first time, a study released today says. Published in today's online edition of Nature Medicine, researchers at the Albert Einstein College of Medicine at Yeshiva University in New York City also say the older organs function as well as they did when the host animal was younger. The researchers, led by Associate Professor Ana Maria Cuervo, blocked the ageing process in mice livers by stopping the build-up of harmful proteins inside the organ's cells. As people age their cells become less efficient at getting rid of damaged protein...
  • Hezbollah Poised to Strike? Officials Say "Sleeper Cells" Activated in Canada

    Intelligence agencies in the United States and Canada are warning of mounting signs that Hezbollah, backed by Iran, is poised to mount a terror attack against "Jewish targets" somewhere outside the Middle East. Intelligence officials tell ABC News the group has activated suspected "sleeper cells" in Canada and key operatives have been tracked moving outside the group's Lebanon base to Canada, Europe and Africa. Officials say Hezbollah is seeking revenge for the February assassination of Hezbollah's military commander, Imad Mugniyah, killed by a car bomb in Damascus, Syria. The group's leaders blamed Israel, an allegation denied by Israeli officials. There...
  • Mothers And Offspring Can Share Cells Throughout Life

    Mothers And Offspring Can Share Cells Throughout Life ScienceDaily (May 5, 2008) ó Cutting the umbilical cord doesnít necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body. A potentially significant one, it turns out. Research implicates that maternal and fetal...

    The Embryology Bill has provoked a bitter split between religion and science THE cries of a baby were the only other sounds to be heard as Cardinal Keith O'Brien delivered his Easter Sunday sermon to a packed St Mary's Cathedral in Edinburgh yesterday. It was perhaps a fitting interruption as Scotland's most senior Catholic clergyman delivered his much-trailed blast at the government's controversial embryo research legislation. Accusing Prime Minister Gordon Brown of "an unprecedented attack on the sanctity and dignity of human life", he warned that the research could lead to the creation of hybrid babies and experiments of "Frankenstein...

    Devices made of heart tissue could screen drug candidates and be used to power implantable robots. In a fourth-floor lab at Harvard University, Adam Feinberg is peering through a low-magnification microscope and using a scalpel to cut out triangles and rectangles from a thin polymer. What's impossible to see with the naked eye is a one-cell-thick layer of heart tissue coating each shape. When Feinberg connects the petri dish holding the triangles and rectangles to a pacemaker, the tissue begins to rhythmically contract, and the shapes come alive--twisting, pinching, and even swimming through a solution. The pieces of "muscular thin...
