    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.

    All sophisticated life on the planet Earth may owe its existence to one freakish event. At first glance, a tree could not be more different from the caterpillars that eat its leaves, the mushrooms sprouting from its bark, the grass growing by its trunk, or the humans canoodling under its shade. Appearances, however, can be deceiving. Zoom in closely, and you will see that these organisms are all surprisingly similar at a microscopic level. Specifically, they all consist of cells that share the same basic architecture. These cells contain a central nucleus—a command center that is stuffed with DNA and...

    Researchers say it may be possible to slow and even reverse aging by keeping DNA more stably packed together in our cells In a breakthrough discovery, scientists report that they have found the key to keeping cells young. In a study published Thursday in Science, an international team, led by Juan Carlos Izpisua Belmonte at the Salk Institute, studied the gene responsible for an accelerated aging disease known as Werner syndrome, or adult progeria, in which patients show signs of osteoporosis, grey hair and heart disease in very early adulthood. These patients are deficient in a gene responsible for copying...

Alberto Nisman said Iran was attempting to set up intelligence-gathering stations in Brazil, Chile, Colombia, and other countries in the region. Mr Nisman is investigating a bomb attack that killed 85 people in a Jewish centre in Buenos Aires in 1994."

    Now that a senior FBI official has admitted openly that it is 'virtually impossible' to screen out terrorists that could be hiding among the thousands of Syrian 'refugees' (heading soon to American cities), maybe we need to be asking why the US is absorbing ANY of these people, when ISIS have said themselves they plan to infiltrate Europe/US disguised as refugees?  What about the other 200 frickin' countries in this world- like an Muslim one! Wouldn't that make a lot more sense? Send them to Turkey, so they can return to Syria/Iraq once ISIS is fully neutralized...The U.S. simply...

    Egypt, now at the forefront of fighting ISIS, is warning it has intelligence revealing the global jihadist group is planning a worldwide offensive this spring or summer that could reach targets within the United States. Interrogations of ISIS members captured in recent weeks in the Egyptian Sinai Peninsula Egyptian and information collected by Egyptian security forces indicate ISIS is planning ground offensives this spring and summer aimed at taking over more territory across the Middle Eastern and Persian Gulf, a senior Egyptian intelligence official told WND. Some of the information indicates the new offensive will not be limited to the...

    Lawmakers are now going public with their concerns that we could see a similar terror attack to what we saw in Paris last week. Some have even said publicly there could be sleeper cells here in the United States. And experts believe Houston remains a prime target for the bad guys. Patrick Poole is a terrorism and national security analyst for PJ Media, and told KTRH our oil and energy industry is what appeals to the terrorists. “Houston is a big sea trade center. You have the oil industry here. And you have a Jamaat ul-Fuqra compound near Houston,” Poole...

    (CNN)French law enforcement officers have been told to erase their social media presence and to carry their weapons at all times because terror sleeper cells have been activated over the last 24 hours in the country, a French police source who attended a briefing Saturday told CNN Terror Analyst Samuel Laurent. Ahmedy Coulibaly, a suspect killed Friday during a deadly Kosher market hostage siege, had made several phone calls about targeting police officers in France. The alert came as the lone remaining suspect wanted in connection with a terrorism spree -- Hayat Boumeddiene -- entered Turkey on January 2,...

    New neurons may explain why adults can’t remember being infants Unlike the proverbial elephants, babies always forget. Infants’ memories may be wiped clean by the genesis of new brain cells, a study in rodents suggests. The findings offer an explanation for why people can’t recall memories from early childhood, a century-old mystery. The study’s authors “make a very interesting and compelling case,” says neuroscientist and psychiatrist Thomas Insel, director of the National Institute for Mental Health in Bethesda, Md. “It’s just truly fascinating,” he says. “Nobody has actually looked at this very carefully before.” More than 100 years ago, Sigmund...

    The living tissue inside an animal has been regressed back into an embryonic state for the first time, Spanish researchers say. They believe it could lead to new ways of repairing the body, for example after a heart attack. However, the study published in the journal Nature, showed the technique led to tumours forming in mice. Stem cell experts said it was a "cool" study, but would need to be much more controlled before leading to therapies.
  • Novel Protein CPTP Offers Hope for Treatment of Cancer and Other Diseases

    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 – powerful signaling molecules that contribute to chronic inflammation in diseases such as cancer, asthma, atherosclerosis and thrombosis – and the discovery of CPTP sheds a light on the cellular mechanisms that contribute to these diseases. "We may have...

    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. Traditional chemotherapy and radiotherapy cause damage to healthy cells, and other more targeted treatments are usually only effective for individual types of cancer. 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...

    Initiative aims to clarify description of mesenchymal cells. Pamela Robey is used to being sent samples by scientists who are anxious to know whether the mesenchymal stem cells (MSCs) they have extracted from fat can be coaxed to turn into either bone or cartilage. Robey, who directs the Stem Cell Unit at the US National Institutes of Health (NIH), is also used to delivering bad news to many of those who seek her help. “They usually are not happy,” she says, when her attempts to differentiate the cells produce little more than fatty globules. To Robey, that disappointment reflects a...

    People with Down's syndrome are at greater risk of heart defects, leukaemia and early-onset dementia. Photograph: Getty Images Scientists have corrected the genetic fault that causes Down's syndrome – albeit in isolated cells – raising the prospect of a radical therapy for the disorder. In an elegant series of experiments, US researchers took cells from people with Down's and silenced the extra chromosome that causes the condition. A treatment based on the work remains a distant hope, but scientists in the field said the feat was the first major step towards a "chromosome therapy" for Down's syndrome....

    A scavenging immune system cell that helps limbs regrow in salamanders brings hope that humans will one day be able to mimic the animal's amazing regenerative powers, say Australian researchers. The findings by Dr James Godwin, of the Australian Regenerative Medicine Institute at Monash University, and colleagues, are published in today's issue of the Proceedings of the National Academy of Sciences.Salamanders (axolotls) are unique amongst vertebrates in being able to repair their hearts, tails, spinal cord and brain, and even regrow whole limbs during adult life, says Godwin. He sees their "perfect regeneration" as a holy grail. "We're trying to...
