The process by which a cell reads the genetic code in its DNA in order to manufacture a protein is complex, involving dozens of enzymes and other biological molecules working together.
Now, research at Cornell University, using the fruit fly as a model system, has confirmed a theory about one step in the process by showing that a protein complex known as FACT is positioned in living cells at sites where chromosomal DNA is unpacked so that its code can be read. It is part of what the resear
Weizmann Institute finding may lead to new treatments for psychological trauma
Is it possible to intentionally forget specific memories, without affecting other memories? Many would undoubtedly be happy to learn that unpleasant memories might be erased. This ability could be especially significant when it comes to the kind of traumatic memories that are debilitating to those experiencing them. It may well be that in the future, we will be able to wipe out, or at least dim, certain typ
The genetic signal that makes a honeybee male or female has been identified by researchers in Germany, the U.S. and Norway. The finding, published in the August 22 issue of the journal Cell, shows how male bees can have no father, a scientific puzzle going back over 150 years and the explanation for why bees, ants and wasps often form colonial societies. It could also make it easier to breed honeybees.
The researchers found that female bees have two different versions of a gene called csd,
“My observations from a few years ago were that Ice Stream D in the West Antarctic was slowing to about half average speed and then speeding up,” says Dr. Sridhar Anandakrishnan, associate professor of geoscience, Penn State.
In the United States, nearly 2.6 million couples have been treated for infertility with about 40 percent of those cases thought to be due to male infertility. Now, a study published in the August 22 issue of Cell identifies a new protein that is required for a sperm to bind to an egg during the process of fertilization. This research provides important new insight into the molecular mechanisms that are involved in the initial events of sperm-egg association and may shed light on what underlies some i
Researchers at the Universities of Essex and Bristol will soon be launching a ground-breaking project to develop a ‘conscious’ robot.
The aim of the project, which involves computer scientists and neuropsychologists, is to advance the technology of intelligent machines, while also extending the understanding of human consciousness.
Owen Holland, Senior Lecturer in Computer Science, who will lead the three-year project at Essex, explained: ‘Consciousness is perhaps the last r
