Moss plants brought back to life after having been frozen in Antarctic ice for 1,500 years

Mosses have existed on Earth for more than 400 million years. During this period they survived many climate catastrophes that wiped out more robust organisms such as, for example, dinosaurs.

25 years after CF gene isolated, researchers still building on its discovery

Twenty-five years ago this month, the medical world was turned on its ear with the isolation of the gene that causes cystic fibrosis, a devastating inherited disease that usually killed children by their late teens. At the helm of the research was Lap-Chee Tsui, who led the team at Toronto's Hospital for Sick Children that made the seminal discovery in collaboration with scientists at the University of Michigan.

Neuroscientists identify key role of language gene

Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans' unique ability to produce and understand speech. Researchers from MIT and several European universities have shown that the human version of a gene called Foxp2 makes it easier to transform new experiences into routine procedures.

Genetics reveals patients susceptible to drug-induced pancreatitis

It has long been recognized that about four per cent of patients who are prescribed particular drugs for IBD go on to develop pancreatitis, an inflammation of the pancreas, which can be fatal. Now researchers have found that 17 percent of patients who have two copies of a particular genetic marker are likely to go on to develop pancreatitis if they are prescribed thiopurine drugs.

Protein secrets of Ebola virus

The current Ebola virus outbreak in West Africa, which has claimed more than 2000 lives, has highlighted the need for a deeper understanding of the molecular biology of the virus that could be critical in the development of vaccines or antiviral drugs to treat or prevent Ebola hemorrhagic fever.

T-Cells Of CVID Patients Cannot Fight All The Gut Bacteria Leaking Into The Bloodstream

Patients with common variable immune deficiency suffer from recurrent bacterial infections due to leaky intestines that cripple bacteria-fighting T-cells. The bacteria residing in our intestines help us digest our food, support our immune systems, and even contribute to the manufacture of certain vitamins.

UNC researchers find final pieces to the circadian clock puzzle

Researchers at the UNC School of Medicine have discovered how two genes - Period and Cryptochrome - keep the circadian clocks in all human cells in time and in proper rhythm with the 24-hour day, as well as the seasons. The finding, published today in the journal Genes and Development , has implications for the development of drugs for various diseases such as cancers and diabetes, as well as conditions such as metabolic syndrome, insomnia, seasonal affective disorder, obesity, and even jetlag.

Schizophrenia is eight different diseases, not one

New research shows that schizophrenia is not a single disease, but a group of eight distinct disorders, each caused by changes in clusters of genes that lead to different sets of symptoms. The finding sets the stage for scientists to develop better ways to diagnose and treat schizophrenia, a mental illness that can be devastating when not adequately managed, says C. Robert Cloninger, co-author of the study published today in the American Journal of Psychiatry.

Stop blaming biology

In her Aug. 18 column in the New York Post, Doree Lewak discusses how she views the act of "catcalling" to be an innocuous form of "self-empowerment" for women, saying that it should deliver a "drive-by dose of confidence" rather than being considered something as negative as street harassment. After reading Lewak's column, I wondered just how common it was for professional or amateur writers as well as online commentators to pass off unacceptable social behavior by saying that it was merely "primal" and has probably existed for centuries, as Lewak did.

Muscular dystrophy: Repair the muscles, not the genetic defect

A potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease. Muscular dystrophies are a group of muscle diseases characterized by skeletal muscle wasting and weakness.

Is your body mostly microbes? Actually, we have no idea

By peering deep into what he called "inner space," scientists discovered that we were never alone: Our bodies have 10 trillion cells, but we are host to 100 trillion microbes. "In other words," Relman said, "we are ten parts microbe, and one part human.
