Infrared sensor as new method for drug discovery

Using an infrared sensor, biophysicists have succeeded in analyzing quickly and easily which active agents affect the structure of proteins and how long that effect lasts. Researchers have performed time-resolved measurements of the changes to the structure of protein scaffolds, which were triggered by the active agents. Their methods might help develop drugs with little side effects in a quick and targeted manner.

Immune discovery should help develop improved vaccines for infants and newborns

Specific immune danger signals are highly efficient in triggering immune responses in infants and newborns, whose immune systems function very differently to those of adults. The scientists believe their discovery could reduce both the age at which vaccines can be first administered, and the need for multiple booster shots.

Discovery of the oldest mammal in Brazil pays tribute to David Bowie

Brasilestes stardusti lived around 70 million years ago and was named after Ziggy Stardust, the singer’s iconic persona. Description was based on a fossilized tooth. It’s the 1st indication that placental mammals and dinosaurs co-existed in South America. For scientists, fossil features showed similarities with another pre-historic mammal found in India, suggesting both shared a common ancestral native from the Gondwana supercontinent.

Surprise cell death discovery provides birth defect clues

Researchers have made a surprise discovery that could rewrite our understanding of the role programmed cell death plays in embryonic development and congenital birth defects. The team showed that, while programmed cell death — or apoptosis — is essential for healthy development overall, many organs and tissues do not require apoptosis to develop normally. The study also suggested that abnormalities in cell death processes are likely to contribute to some common birth defects in humans, such as spina bifida, heart vessel defects and cleft palate.

Discovery of differences in the brains of rats classified as workers vs. slackers

Neurologists have uncovered a network of regions in the brain that are involved in determining the choice of being a ‘hard-worker’ or a ‘slacker.’ Understanding how the brain makes such decisions is one of the most fundamental questions in neuroscience and psychology, and sophisticated animal behavioral testing, coupled with advance brain imaging and stimulation techniques are shedding light on this important process.
