Scientists make breakthrough in understanding how penicillin works

The mechanism which allows β-lactam antibiotics, including penicillin, to kill MRSA has been revealed for the first time. An international team of researchers led by the University of Sheffield discovered that β-lactam antibiotics kill MRSA (Methicillin Resistant S. aureus) by creating holes in the cell wall which enlarge as the cell grows, eventually killing the […]

Sharpest images ever reveal the patchy face of living bacteria

The sharpest images ever of living bacteria have been recorded by UCL researchers, revealing the complex architecture of the protective layer that surrounds many bacteria and makes them harder to be killed by antibiotics. The study, published today in Proceedings of the National Academy of Sciences of the USA and done in collaboration with scientists at National […]

Possible dinosaur DNA discovered in 125-million-year-old fossil

A team of researchers found what seems to be DNA in a 125-million-year-old dinosaur fossil – though how the fragile biomolecules survived fossilisation remains a mystery. Alida Bailleul, a palaeontologist from the Chinese Academy of Sciences, and her colleagues found the biomolecules in a portion of cartilage from a Caudipteryx specimen. This peacock-sized theropod dinosaur […]

That primate’s got rhythm!

Songbirds share the human sense of rhythm, but it is a rare trait in non-human mammals. An international research team led by senior investigators Marco Gamba from the University of Turin and MPI’s Andrea Ravignani set out to look for musical abilities in primates. “There is longstanding interest in understanding how human musicality evolved, but […]

Men, women ride the same emotional roller coaster

Contrary to widely held gender stereotypes, women are not more emotional than men, researchers say. Feelings such as enthusiasm, nervousness or strength are often interpreted differently between the two genders. It’s what being “emotional” means to men vs. women that is part of a new University of Michigan study that dispels these biases. For instance, […]
