4:00 AM | Il lato scuro dell’Universo secondo Michael Turner
Come materia scura ed energia scura hanno contribuito a modellare l’Universo e controlleranno il suo destino? Sono alcune delle domande aperte a cui oggi stanno tentando di dare una risposa gli scienziati. Il cielo è riempito di centinaia di miliardi di galassie, ognuna contenente centinaia di miliardi di stelle. Tuttavia, le stelle contribuiscono meno dell’1 … Continue reading Il lato scuro dell’Universo secondo Michael Turner →

11:18 PM | Did climate change help spark the Syrian war?
A new study says a record drought that ravaged Syria in 2006-2010 was likely stoked by ongoing manmade climate change, and that the drought may have helped propel the 2011 […]

7:42 PM | New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

5:16 PM | Researchers use lab-scale human colon to study impact of copper nanoparticles on the environment
What do a human colon, septic tank, copper nanoparticles and zebrafish have in common? They were the key components used by researchers to study the impact copper nanoparticles, which are found in everything from paint to cosmetics, have on organisms inadvertently exposed to them.

4:42 PM | Scientists observe the current flow along nanochannels at the crystal surfaces of topological insulators
Scientists report that they could observe experimentally the current flow along channels at the crystal surfaces of topological insulators. The channels are less than one nanometer wide and extend along atomic steps of the crystal lattice. The scientists demonstrated also how these steps can be introduced in any arrangement.

2:47 PM | Celebrities and Attention Police
While I’m running unrelated articles head-on into each other, two other things that caught my eye recently were Sabine Hossenfelder’s thoughts on scientific celebrities (taking off from Lawrence Krauss’s defense of same) and Megan Garber’s piece on “attention policing”, spinning off that silliness about a badly exposed photo of a dress that took the Internet…

2:30 PM | New analysis shows ion slowdown in fuel cell material
Dislocations in oxides seen as promising electrolytes create a 'traffic jam' for charged ions.

2:23 PM | Smart crystallization
The first semi-liquid, non-protein nucleating agent for automated protein crystallization trials is described. This 'smart material' is demonstrated to induce crystal growth and will provide a simple, cost-effective tool for scientists in academia and industry.

2:18 PM | The first ever photograph of light as a particle and a wave
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists have succeeded in capturing the first-ever snapshot of this dual behavior.
