- both parts of this are well worth a watch, was a bit sceptical after the first one myself...kingsteven
- A professor of physics, Bill Nye and Neil deGrasse Tyson all proven wrong...bunch of arrogant, know-it-all, attention whores.utopian
- The great thing is though that the scientist who made the bet admitted he was wrong and coughed up the $10K! Science is a process, not an authority.sarahfailin
- yeah so cool, loved the mike drop moment at the end with the wheeled cart and piece of wood._niko
- @sarah, exactly. And acting like three individuals are “science” is ridiculous. They aren’t even the ones actively sciencing!monospaced

‘Holy grail’ battery breakthrough sees scientists solve 40-year problem
Lithium-metal batteries hold far more energy and charge in a fraction of the time compared to those used in smartphones and electric carsResearchers have demonstrated a solution to a 40-year problem regarding the creation of a “holy grail” battery that could radically transform the electric car industry.
The breakthrough involves harnessing the power of lithium-metal batteries, which are capable of holding substantially more energy and charge in a fraction of the time compared to lithium-ion batteries that are currently used in everything from smartphones to Tesla vehicles.
Until now, scientists have been unable to create a lithium-metal battery stable enough to be used in commercial applications.
The development, made by a team at Harvard University’s School of Engineering and Applied Science (SEAS), allows this next-generation batter to be charged and discharge at least 10,000 times, which would increase the lifetime of electric vehicles to that of of their gasoline counterparts – while simultaneously increasing their range and reducing their charge time.
“A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density,” said Xin Li, an associate professor at SEAS.
“But the stability of these batteries has always been poor... By studying their fundamental thermodynamics, we can unlock superior performance and harness their abundant opportunities.”
The research, published in the journal Nature on Wednesday, involves an innovative multi-layer approach to assemble the battery, which allows it to be self-healing and solve the issue of degradation.

- i don't have a tinfoil hat but 5G as an accidental wireless power grid for wearable iot options kinda speaks to its power and invasiveness; tanning alternative?prophetone

Scientists Might Have Just Stumbled Upon a New Kind of Physics
You never know what you'll find at the Large Hadron Collider.

“If a violation of lepton flavour universality were to be confirmed, it would require a new physical process, such as the existence of new fundamental particles or interactions,” says LHCb spokesperson Professor Chris Parkes
Looking towards the future, the LHCb experiment is well placed to clarify the potential existence of new physics effects hinted at in the decays presented today. The LHCb experiment is expected to start collecting new data next year following an upgrade to the detector.

Most slime molds are smaller than a few centimeters, but some species may reach sizes up to several square meters and masses up to 20 kilograms.
Many slime molds, mainly the "cellular" slime molds, do not spend most of their time in this state. When food is abundant, these slime molds exist as single-celled organisms. When food is in short supply, many of these single-celled organisms will congregate and start moving as a single body. In this state they are sensitive to airborne chemicals and can detect food sources. They can readily change the shape and function of parts, and may form stalks that produce fruiting bodies, releasing countless spores, light enough to be carried on the wind or hitch a ride on passing animals.
