Newton’s Principia Manuscript
One of the greatest treasures in science – Isaac Newton’s “Principia” – was nearly thwarted by a book about fish. Royal Society head librarian Keith Moore and explains to Brady Haran.
Synthetic Muscles
NASA supported researchers are working on Synthetic Muscles that could be used to create humanoid robots for space exploration.
Epigenetics – packaging artists in the cell
Methyl attachments to histone proteins determine the degree of packing of the DNA molecule. They thereby determine whether a gene can be read or not. In this way, environment can influence the traits of an organism over generations.
How does your brain decode garbled speech?
UC Berkeley
UC San Francisco (UCSF)
Humans are exquisitely skilled at perceiving spoken words, even when speakers’ voices are intermittently overwhelmed by noise, as happens in the din of construction sites or on busy urban streets. Now, in a study conducted in a group of patients preparing for brain surgery, UC San Francisco scientists have discovered an unexpected mechanism the brain uses to seamlessly compensate when speech sounds are obscured by noise.
Accelerator Science: Why RF?
Particle accelerators can fire beams of subatomic particles at near the speed of light. The accelerating force is generated using radio frequency technology and a whole lot of interesting features. In this video, Fermilab’s Dr. Don Lincoln explains how it all works.
