A new male contraceptive pill could be developed after researchers in Edinburgh, UK, have identified a gene critical for the production of healthy sperm. Experiments in mice found that the gene, Katnal1, was vital for the final stages of making sperm. The authors of a study in PLos Genetics said a drug which interrupts Katnal1 could be a reversible contraceptive. A fertility expert said there was...

Herschel space telescope in Europe has imaged one of the most popular subjects in the sky – the Horsehead Nebula – and its environs. Horsehead Nebula is a distinctively shaped molecular gas cloud sited some 1,300 light-years from Earth in the Constellation Orion. It is in a region of space undergoing active star formation – something Herschel has been most keen to study. The Hub...

When he treated hippocampal cells with moderate amounts of alcohol, the key areas for memory formation were unaffected, but exposing the cells to large amounts of alcohol inhibited the memory formation mechanism. “It takes a lot of alcohol to block memory,” said senior investigator Charles F. Zorumski. “But the mechanism isn’t straightforward. The alcohol triggers receptors to behave in se...

NASA has reported that its Curiosity rover has made another significant discovery on Mars. Curiosity has drilled into a rock that contains clay minerals – an indication of formation in, or substantial alteration by, neutral water. Scientists say the find is one more step towards showing conditions on Mars in the distant past could have supported life. Many rocks studied previously were prob...

Russian scientists have released microscopic images of fragments of the meteorite that hit the central city of Chelyabinsk in February. A team from the Ural Federal University was able to analyze some of the dozens of samples as soon as they were found. But the technique they used allowed them to assess the rock’s chemical make-up at the microscopic level even as they snapped pictures of th...

US researchers have uncovered how bacteria may set off a chain reaction leading to bowel cancer. Fusobacteria, commonly found in the mouth, cause overactive immune responses and turn on cancer growth genes, two studies reveal. The microbes had been linked with colorectal cancer before but it was not known whether they were directly involved in tumor growth. The early findings are published in the...

A new research suggests that frenetic star-forming activity in the early Universe is linked to the most massive galaxies in today's cosmos

A new research suggests that frenetic star-forming activity in the early Universe is linked to the most massive galaxies in today’s cosmos. This “starbursting” activity when the Universe was just a few billion years old appears to have been clamped off by the growth of super massive black holes. An international team gathered hints of the mysterious “dark matter” in...

Scientists at the University of York are one step closer to understanding the origin of life after making a breakthrough into how sugar molecules found in DNA are created. They have recreated a pair of simple sugars – threose and erythrose – in a process which could have occurred before the advent of life.

Astronomers wanted to find out how Milky Way galaxy looked from the outside – a difficult task given the Earth is inside it. A comparison of star types in other galaxies gives perhaps an unsurprising result: white. But not just any white – specifically, like spring snow at an hour after sunrise or before sunset. The finding was announced at the 219th American Astronomical Society meet...

Eating too much red meat could increase the risk of Alzheimer's

0 68

According to a recent research, eating too much red meat could trigger Alzheimer’s disease. Scientists found that a build-up of iron – abundant in red meat – could cause oxidant damage, to which the brain is particularly vulnerable. Researchers say this could in turn increase the risk of Alzheimer’s. Prof. George Bartzokis of UCLA said that more studies have suggested the...

A lifetime of too much copper in our diets may be contributing to Alzheimer's disease

US scientists have found that a lifetime of too much copper in our diets may be contributing to Alzheimer’s disease. However, research is divided, with other studies suggesting copper may actually protect the brain. The latest study in Proceedings of the National Academy of Sciences showed high levels of copper left the brain struggling to get rid of a protein thought to cause the dementia....

New research supports an idea that the Red Planet was a better place to kick-start biology billions of years ago than the early Earth was

A new research presented at the Goldschmidt Meeting in Florence, Italy, say that life may have started on Mars before arriving on Earth. The research supports an idea that the Red Planet was a better place to kick-start biology billions of years ago than the early Earth was. The evidence is based on how the first molecules necessary for life were assembled. Details of the theory were outlined by...
