Research team identifies new Alzheimer's gene

...process for creating a new diagnostic test that is capable of detecting the presence of GAB2, and may ultimately help millions of individuals reach a more informed decision regarding the most appropriate type and timing of treatment,” said Dr. Chris Heward, President of Kronos Science Laboratory. Until re...

Brightening prospects of using fluorescent nanotubes in medical applications

...gle-walled semiconducting nanotubes, or SWNTs, are capable of producing light. Metallic nanotubes actually inhibit the brightness of their fluorescent neighbors. But it has been very difficult to separate the strongly fluorescent SWNTs from all the rest in large quantities. Nanotube soot is insoluble in wa...

Salty oceans provide early warning for climate change

...eam and its North Atlantic deep water partner) are capable of shifting gears very suddenly, but until now it wasn’t clear how this occurred. Using a combination of modern observations, numerical models and palaeoclimate data scientists are increasingly realising that salt is the key. Their results reveal ...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

... finger-like projections from the surface of cells capable of moving molecules around. However, mutations in the LCA5 gene only appear to cause defects in the retina. "We already know of a dozen genes which, when mutated, cause LCA," says Professor Chris Inglehearn from the Leeds Institute of Molecular Me...

Undergraduate research shows leaderless honeybee organizing

...ty ends. Bees do not have large brains and are not capable of complex thought like humans. Though the bee colony is centered around the queen and her reproductive capabilities, findings by Schneider and others indicates that she does not exactly “rule.” Instead, the colony appears to be controlled by the an...

Plants recognize their siblings, biologists discover

...k cognition and memory, the study shows plants are capable of complex social behaviours such as altruism towards relatives, says Dudley. Like humans, the most interesting behaviours occur beneath the surface. Dudley and her student, Amanda File, observed the behavior in sea rocket (Cakile edentula), a me...

Exploring the dark matter of the genome

...ilar to viruses that hop around the genome and are capable of disrupting gene function. "Drosophila is ideal for studying genomics for many reasons, and especially for studying heterochromatin," says Susan Celniker, a scientist in Berkeley Lab's Life Sciences Division and a longtime member of the Berkele...

Warning from Asian bees

...ry sigh of relief. Asian bees (Apis cerana) are capable of carrying two types of Varroa mite – destructor and jacobsoni; the latter would not threaten the health of local bee populations but destructor has wiped out commercial hives and feral populations the world over and Australia is the last remaining ...

...f a cytokine known as interleukin-6 (Il-6) is also capable of stimulating AVP secretion. Verbalis noted in his Sports Medicine paper that since 1985, “well over 100 individual cases” of EAH have been reported from physical exercise activities as diverse as forced military marches, prolonged hiking and ...

Weizmann Institute scientists develop a general 'control switch' for protein activity

This segment is capable of binding strongly and selectively to a particular chemical drug, which affects the activity level of the engineered protein by increasing or reducing it. When the drug is no longer applied, or when it is removed from the system, the protein returns...
