Scientists find evidence the early solar system harbored a gap between its inner and outer regions

Posted: 15 Oct 2021 03:42 PM PDT

In the early solar system, a 'protoplanetary disk' of dust and gas rotated around the sun and eventually coalesced into the planets we know today. A new study suggests that a mysterious gap existed within this disk around 4.567 billion years ago, and likely shaped the composition of the solar system's infant planets.

Ultrafast magnetism: heating magnets, freezing time

Posted: 15 Oct 2021 03:42 PM PDT

Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this principle. However, the microscopic mechanisms of ultrafast demagnetization remain unclear. Now, a team has developed a new method at BESSY II to quantify one of these mechanisms and applied it to the rare-earth element Gadolinium, whose magnetic properties are caused by electrons on both the 4f and the 5d shells.

Plant-based jet fuel could reduce emissions by 68%

Replacing petroleum-based aviation fuel with sustainable aviation fuel derived from a type of mustard plant can reduce carbon emissions by up to 68%, according to new research.

Expansion of wind and solar power too slow to stop climate change

Posted: 14 Oct 2021 11:19 AM PDT

The production of renewable energy is increasing every year. But after analyzing the growth rates of wind and solar power in 60 countries, researchers conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article "National growth dynamics of wind and solar power compared to the growth required for global climate targets" was published in the journal Nature Energy, written by Aleh Cherp, Vadim Vinichenko, Jale Tosun, Joel A.Gordon and Jessica Jewell.

Scientists develop fully solar-driven autonomous chemical mini-plant

Scientists have developed a fully operational standalone solar-powered mini-reactor which offers the potential for the production of fine chemicals in remote locations on Earth, and possibly even on Mars.

Climate change threatens hydropower energy security in the Amazon basin

Posted: 14 Oct 2021 10:11 AM PDT

Hydropower is the dominant source of energy in the Amazon region, the world's largest river basin and a hotspot for future hydropower development. However, a new study warns that in the coming decades, climate change-driven reductions in precipitation and river discharge will diminish the Amazon's hydropower capacity.

Artificial intelligence-based technology quickly identifies genetic causes of serious disease

Posted: 14 Oct 2021 07:02 AM PDT

An artificial intelligence (AI)-based technology rapidly diagnoses rare disorders in critically ill children with high accuracy. The benchmark finding foreshadows the next phase of medicine, where technology helps clinicians quickly determine the root cause of disease so they can give patients the right treatment sooner.
