Blink, and the brain misses it

...ely notice if the outside world suddenly went dark every few seconds. But we rarely become aware of our blinks, even though they cause a similar reduction in the amount of light entering the eye. So why are we not aware of the frequent mini-blackouts caused by blinks? In the 1980s, scientists discovered t...

Caloric restriction won't dramatically extend life span in humans: UCLA research

...nd begins reproducing its body weight in offspring every month and a half. If humans shut off reproduction by severely limiting calories, "our reduction in wear and tear on the body is minimal," he said. The rodents placed on severely restricted diets bit people who tried to hold them, and had an unpleasa...

New Vaccine To Be Used For First Time In Polio Outbreak Response

...th high quality immunization campaigns which reach every child under five years old. Dedicated donor support and strong partnerships with the private sector have enabled the previous campaign in Yemen as well as swift development of the mOPV1 vaccine. However, a global funding gap of US$ 50 million must u...

International Team Determines Geographic Origin of Leprosy

...rganisms, M. leprae has very few SNPs ?only one in every 28,400 letter pairs. The rarity of SNPs is an indication of extreme genetic stability: all the strains of leprosy throughout the world are essentially identical. The discovery of the four SNP types could help health officials better understand lepro...

Malaria killing a million a year

...disease that kills one child in sub-Saharan Africa every 30 seconds. The numbers are astounding -- and unacceptable." Insecticide-treated bed nets and new artemisinin-based combination therapies must reach many more people, but "many countries are moving forward with malaria control programmes and even th...

... are one of the most ancient cell types, needed by every type of animal to reproduce," Van Doren said. "Their developmental program is very similar, whether we are talking fruit flies or humans. As a result, these findings could eventually help us understand and treat defects in germ cell development that ...

Gifts from the sea

... from around the world, who return here faithfully every summer to study the squid and other marine organisms. Sea creatures, it turns out, have been at the center of numerous medical research breakthroughs, and the MBL has been a center for this kind of work for over a century. The laboratory's proximity...

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

...f hydrating solution, was then given intravenously every four minutes. As the researchers alerted participants that the placebo was coming, and injected the placebo dose, the amount of additional concentrated salt water needed to maintain participants' pain over time increased -- indicating a reduction in...

Micro-molecule plays big role in birth defects

...s normal." Had researchers inhibited microRNAs in every single cell, Harfe said the mouse embryos would survive little more than seven days after fertilization. "That isn't enough time to study development," Harfe said. "Most structures, such as the heart, the gut and the lungs, haven't even formed yet. ...

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...ut caused encephalitis complications in about 1 of every 10,000 people. Interferon, the body's first defense against many viruses, triggers a cascade of immune defenses. According to researchers at NIAID's Rocky Mountain Laboratories (RML) in Hamilton, MT, NS5 blocks the body's attempt to signal for immun...

Fundamental discovery -- Bone fracture

...nimals." He said that a paper on bone is published every six minutes. And although bone is extensively studied, little is known about how it works at the molecular level. "Our paper is the beginning research on this." Hansma and his colleagues at UCSB have pioneered the use of the Atomic Force Microscope ...

For first time, brain cells generated in a dish

...ring the process, they snapped images of the cells every five minutes for up to 30 hours and compiled the images into movies. Traditional ways to attempt neurogenesis have been unable to so closely duplicate the natural process. They also haven't allowed scientists to monitor the entire sequence of cell de...
