Bacterial walls come tumbling down

... identifying bacterial components whose structural features might have weaknesses that can be exploited by antibiotics, progress in turning up bona fide drug targets has been slow. The cell wall enzymes in particular have tantalized scientists, Strynadka said. "The cell wall has all the hallmarks of a great d...

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

Antifungal drug kills TB bug

... in the body. We also realised that these peculiar features of the TB bacterium must mean that there are ‘unusual?aspects of its composition and biochemistry that set it apart from most other bacteria and that could provide new targets for antibiotic drugs. "When we began looking at the bug and its DNA con...

Trusting your instincts leads you to the right answer

... that allows us to pick out unique and distinctive features in a crowd ?such as colour or orientation. Soon after our eyes have fixed on a target, the conscious or top-down part of cognition engages and examines whether the candidate really is the target or not. If the target is not distinctive enough in the ...

Paleontologists discover new mammal from Mesozoic Era

...he mammalian middle ear--one of the most important features for all modern mammals. The discovery was funded by the National Science Foundation (NSF). "This early mammalian ear from China is a rosetta-stone type of discovery which reinforces the idea that development of complex body parts can be explained ...

OHSU lab finds meth receptor that could lead to therapy

... of TAAR1. In other words, TAAR1 has the necessary features to be considered a real target of methamphetamine and amphetamine in rodents and probably humans, too." Grandy added that it's his hope that "these findings will eventually lead to the development of new pharmaceuticals that reduce dependence on a...

Scientists map key landmarks in human genome

... major new clues to the locations of many hallmark features of the human genome, such as where transcription factors bind, where transcription begins and possibly ends, and where there are other biologically important structural features," said Fisher. Transcription factors are proteins that bind to particula...

Some caterpillers just don't want to grow up

...gitations from the nurse ants. One of the peculiar features of this species' ecology is that only about 25% of the caterpillars complete development within one year. The rest are inactive in the first season and mature only after two years. "The question puzzling us for some time," says Prof. Jeremy Thomas, d...

Researchers discover genetic cause for word-finding disease

...at causes the disease but the uniquely identifying features of human language. That's a pretty big question," added Mesulam. MRI imaging of the brains of people with PPA shows the language part in the perisylvian region of the left hemisphere has shrunk. By comparison, Alzheimer's Disease targets the hipp...

Computer imaging assists with facial reconstructive surgery

...before surgery so that afterward, prominent facial features such as the chin and nose are balanced in relation to the structures around them. “Even a well-executed surgery will result in a poor aesthetic result if inaccurate analysis leads to an improper decision (e.g., an excessively large chin implant).? ...
