Researchers are studying adding carbon capture technologies to vehicles so that the CO₂ can be sequestered or recycled into renewable hydrocarbon fuels.

According to senior researcher of the study; “This technology really doesn’t have any major hurdles to making it work,”

When people talk about how to eliminate vehicles’ carbon dioxide (CO₂) emission, often the conversation often focuses on electrifying cars, trucks and buses. Yet cargo and tanker ships, which are responsible for 3% of all CO₂ emissions, are rarely a part of the discussion.

Over the last few decades, various forms of solar power stations have been proposed from around the world but they remained theoretical because of major technical challenges.

At Bishan, Chinese researchers would first need to prove that wireless power transfer worked over a long distance.

Civilian and military researchers will look at applications for the technology amid concerns about radiation and the potential for beams misfired from space.

NASA has confirmed that SpaceX’s next Falcon 9 launch is now scheduled to occur no earlier than 3:37 am EDT (07:37 UTC) on Saturday, August 28th.

Known as CRS-23, the cargo resupply mission to the International Space Station (ISS) is noteworthy for two major reasons. Most importantly, CRS-23 will mark SpaceX’s first-ever reuse of an upgraded Cargo Dragon 2 spacecraft. Simultaneously, that reuse milestone will coincide with another when SpaceX smashes its internal record for orbital spacecraft turnaround later this month.

Second, much to the surprise of virtually everyone watching from the sidelines, SpaceX’s last launch occurred on June 30th – in the first half of 2021. One step removed from the mission’s technical specifics, CRS-23 will, in other words, also be SpaceX’s first launch in almost two months – a gap not seen in two years.

Not the movie version.

The peculiar ‘brainless blob’ will take part in an interesting experiment that will take place both in space and on land.

An increase in counterspace weapons is challenging the military’s approach of placing all of its billion-dollar eggs (exquisite satellites) in one basket (far-out geosynchronous orbit).

Lawrence Livermore National Laboratory (LLNL) researchers have explored high-pressure behavior of shock-compressed tantalum at the Omega Laser Facility at the University of Rochester’s Laboratory for Laser Energetics (LLE). The work showed tantalum did not follow the predicted phase changes at high pressure and instead maintained the body-centered cubic (BCC) phase until melt.

The results of the work are featured in a Physical Review Letters paper and focuses on how researchers studied the melting behavior of tantalum at multi-megabar pressures on the nanosecond timescale.

“This work provides an improved physical intuition for how materials melt and respond at such extreme conditions,” said Rick Kraus, lead author of the paper. “These techniques and improved knowledge base are now being applied to understanding how the iron cores of rocky planets solidify and also to more programmatically relevant materials as well.”

Two-dimensional supersolidity is demonstrated using highly magnetic, ultracold dysprosium atoms.

MECII-originating type 2 dentate spikes (DSM) promote dominance of CA1 slow (∼40-Hz) over mid-frequency (∼80-Hz) gamma oscillations when CA1 represents non-local recollections. Dvorak et al. show that DSM coordinates cofiring within DG, CA3, and CA1 networks and optimizes discharge timing between DG and CA1 for information transfer during memory recall.

The Breit-Wheeler process which produces matter and antimatter from photon collisions is experimentally investigated through the observation of 6085 exclusive electron-positron pairs in ultraperipheral Au+Au collisions at √sNN=200 GeV. The measurements reveal a large fourth-order angular modulation of cos4Δϕ=(16.8±2.5)% and smooth invariant mass distribution absent of vector mesons (ϕ, ω, and ρ) at the experimental limit of ≤0.2% of the observed yields. The differential cross section as a function of e+e− pair transverse momentum P⊥ peaks at low value with √⟨P2⊥⟩=38.1±0.9 MeV and displays a significant centrality dependence. These features are consistent with QED calculations for the collision of linearly polarized photons quantized from the extremely strong electromagnetic fields generated by the highly charged Au nuclei at ultrarelativistic speed. The experimental results have implications for vacuum birefringence and for mapping the magnetic field which is important for emergent QCD phenomena.
