7:36 PM | The Evolution of Evolution: Gradualism, or Punctuated Equilibrium?
In some ways I’m glad I’m not an evolutionary biologist, even though the subject matter is undoubtedly fascinating and fundamental. Here in the US, especially, it’s practically impossible to have a level-headed discussion about the nature of evolutionary theory. Biologists … Continue reading →

1:23 PM | Rare 'baby rattle' molecules reveal new quantum properties of H2O and H2
Neutron scattering experiments have revealed the existence of quantum selection rules in molecules, the first experimental confirmation of its kind. Small molecules such as water and hydrogen were inserted into C60 buckyballs to form rare compounds ideal for testing the predictions of quantum theory. Similar confinement techniques could open the door to new insights about the quantum properties of molecules by providing a unique testing ground for quantum theory.

1:13 PM | La scoperta di un nuovo mesone fornisce nuovi indizi per lo studio dell’interazione forte
Un gruppo di fisici guidati dai colleghi dell’Università di Warwick hanno scoperto una particella che contribuirà a fornire una maggiore comprensione dell’interazione forte, una delle quattro forze fondamentali della natura che tiene uniti i protoni del nucleo atomico. Denominata con la sigla Ds3 * (2860) ˉ, si tratta di un nuovo tipo di mesone, cioè un gruppo […]

12:33 PM | Chandra Awaits Comet Siding Spring's Approach to Mars
On October 19th, Chandra will join with telescopes across the world, in orbit around Earth, and even on and around Mars, as Comet Siding Spring makes an extremely close approach to the Red Planet. This is an extremely exciting event because scientists have determined this comet has been traveling for maybe a million years from the distant Oort Cloud. This will be the first time that humans have ever captured images of a comet from the Oort Cloud, which is an enormous reservoir of left over […]

Scanning-tunnelling-microscope image showing a chain of iron atoms. The inset shows the probability that Majorana quasiparticles reside in that portion of the chain. The dark red blob at the tip indicates high probability at the tip. (Courtesy: Yazdani Lab, Princeton University)The strongest evidence yet that Majorana quasiparticles (MQPs) can be found lurking in some solids has been unveiled by physicists in the US. The team used a scanning tunnelling microscope (STM) to locate MQPs at the […]

8:37 AM | CNT@NCNT coaxial nanocables - Toward full exposure of 'active sites'
Researchers have demonstrated a unique coaxial carbon nanocable material with pristine carbon nanotubes as the core and nitrogen-doped wrinkled carbon layer as the shell. The active sites rendered by the surface enriched dopant atoms on the carbon nanocables are accessible and effective to catalyze the oxygen involved electrochemical reactions. These coaxial nanocables afford higher ORR/OER current compared with the routine bulk doped nitrogen-doped carbon nanotubes.

Early results demonstrate the entire complement of building blocks for integrated circuits, along with various sensors and actuators with relevance to clinical medicine, including most recently intracranial monitors for patients with traumatic brain injury. The advances suggest a new era of devices that range from green consumer electronics to 'electroceutical' therapies, to biomedical sensor systems that do their work and then disappear.
