MIT finds most complex protein knot ever seen

...u said. Until now, scientists have not paid much attention to knots in proteins, but the MIT researchers hope their work will ignite further interest in the subject. "We just hope this will become a part of the routine crystallographers and NMR spectroscopists do when they solve a structure," Mirny said. V...

High dopamine transporter levels not correlated with ADHD

... transporters play an important role in modulating attention in all people. Yet, for a given level of dopamine transporters, scores of inattention were, on average, five times greater for ADHD subjects than for controls in this study. "These findings suggest that an additional variable in conjunction with do...

What animals can tell us about hemorrhage, organ transplants and aging

...said. But physiologists have recently turned their attention to long-lived animals. Some of the aging theories to be discussed during the symposium: DNA damage and repair. Short-lived animals may suffer more damage to their genes and have a more difficult time repairing the damage than long-lived animals,...

New finding points way to foiling anthrax's tricks

...ritical to growth, it has become a recent focus of attention as a possible drug target. Raymond, who has studied bacterial siderophores that capture iron for 35 years, recently teamed up with Roland Strong of the Seattle cancer center to study siderocalin, a human protein Strong had found that appeared to inte...

Yellows "beat" orange because the bullies aren't sticking close enough to home to keep an eye on things. Research has focused on why the blue throats are willing to cas...

New study finds similarities between monkey business and human business

Little attention has been paid to whether systematic economic biases such as risk-aversion are learned behaviors ?and thus easily ameliorated through market incentives ?or biologically based, arising in novel situations and in spite of experience. In a groundbreaking...

Free radical cell death switch identified

... in neurons from rat brain, the team focused their attention on the function of a protein called MST, which had been previously implicated in cell death. They found that exposure of brain neurons to oxidative-stress signals stimulates the activity of MST, and once activated, MST instructs neurons to die. The ...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...This research breakthrough came when we turned our attention to primordial germ cells, the precursor cells to sperm and eggs," said Marie-Cecile van de Lavoir, senior scientist at Origen. "These cells ?which we are the first to successfully culture without changing their commitment -- proved to be the key to i...

Massive duplication of genes may solve Darwin's 'abominable mystery' about flowering plants

... traces. Whole-genome duplications have attracted attention as a possible mechanism to drive sudden bursts of evolution, like the one that so vexed Darwin over a century ago. While the vast majority of duplicate genes quickly accumulate mutations and are deleted from the genome, a few mutations will be selec...

Discovery could aid fight against cystic fibrosis infection

...d confirmed the hypothesis. They then turned their attention to Hcp1 in cystic fibrosis patients to gain more insight in the role of Hcp1 during infection. Working with cystic fibrosis patients at Children's Hospital Boston, the HMS researchers sought and found Hcp1 in the sputum of patients with P. aerugin...

Choosy females make colourful males

...nt characteristics in males. Yet females often pay attention to traits that reveal something about the quality of a male. As a result, females are likely to share the same preferences. In Lake Victoria cichlid fish, Martine Maan found a solution for this paradox: in different species, different traits reveal m...

Tigers get a business plan

Observing wild population of guppies in the rainforest of Trinidad, the researchers found that female guppies swim in habitats that contain few males ?but many predators. "Male guppies spend most of their time displaying to females. But ...
