No sex for 40 million years? No problem

...hat the differences might arise solely through the chance build-up of random mutations that occur in the 'cloning' process when a new rotifer is born. The new study proves that these differences are not random and are the result of so-called 'divergent selection', a process well known to cause the origin of...

Gene hunters close in on Lou Gehrig’s disease

... dice 555,352 times, you are bound to get lucky by chance alone on some of those throws,?he says. “The next step is to go back and figure out which of these ‘hits?are real and which are false.? Thousands of other SNPs were more weakly associated with ALS, some of which could turn out to be just as import...

As well as publishing new research and running events, SCI has a growing database of member specialists who can...

Baby fish 'smell their way home'

...was a lot more than you'd expect to happen by pure chance ?and it applied, in differing degrees, across several species of fish," Mike says. The fish could also be responding to other stimuli, including distant noise off a reef and the behaviour of other fish, but the team concluded that smell was probab...

A revolution in the monitoring of unborn babies

...ses, the more we can monitor them, the greater the chance of us detecting that they are running into difficulties before it is too late to help them. This may involve urgent delivery of the fetus.? The device will be especially helpful in monitoring fetuses whose mothers have medical conditions like diabe...

Anti-dandruff compound may help fight epilepsy

... a defective protein work better. So now we have a chance to actually try to fix the causes of epilepsy, rather than traditionally circumventing them. Plus, this study really shows that we don’t fully appreciate the biological roles of many familiar chemicals that surround us.? ...

Light-based probe 'sees' early cancers in first tests on human tissue

...es of cancer by catching it early, before it has a chance to develop further or spread." In some instances, the technique, known as "fa/LCI" (frequency-domain angle-resolved low coherence interferometry), might ultimately enable doctors and their patients to avoid removal of tissue for biopsy, Wax said. ...

UCLA: How does your brain respond when you think about gambling or taking risks?

Biologists call for better choice of model organisms in 'evo-devo'

... models in this way leaves it entirely a matter of chance whether a new model will illuminate a particular evo-devo theme. "Instead, we urge workers to select new models specifically to illuminate hitherto neglected general themes within evo-devo.". In other cases, new model organisms are chosen on t...

Chromosomal microarray analysis proves accurate

...in all children, but there is a five to 12 percent chance that it will identify an abnormality in children with various disabilities where the previous chromosomal testing did not. This study involved two versions of the test, and the newer version was more successful in identifying chromosomal abnormalitie...

St. Jude announces breakthrough in eye cancer treatment

The discovery that blocking MDMX releases the apoptosis response in retinoblastoma has important implications for certain ...

Dopamine used to prompt nerve tissue to regrow

... that the material with dopamine may have a better chance to successfully repair damaged nerves. The success of dopamine has encouraged the team to set its sights on other neurotransmitters. "Dopamine was a good starting point, but we are looking into other neurotransmitters as well," Wang said. Th...

Proteins may predict lung transplant rejection

Finally, these findings could be used to understand the physiological mechanisms that lead to lung rejection, Wendt explained. Her team has developed two mouse models to determine whether these protei...

Neuron cell stickiness may hold key to evolution of the human brain

...out 79-percent more than we would expect to see by chance at our assigned probability threshold." When Prabhakar and Noonan ran an analysis to determine whether the accelerated CNSs disproportionately occurred near genes with particular functions, they discovered that neuronal cell adhesion was the only...

Why don't all moles progress to melanoma?

...id of excess incoming amino acids, giving the ER a chance to catch up. If that doesn't work, the UPR causes the cell to destroy itself in a process called apoptosis. "Traditionally, the ER's role was considered to be limited to protein folding or protein modification," Soengas says. "But scientists like R...
