The Air Force Research Laboratory awarded SpaceX an $8.5 million contract to investigate manufacturing techniques for heat shields that protect hypersonic vehicles in flight.

WASHINGTON — The Air Force Research Laboratory awarded SpaceX an $8.5 million contract to investigate advanced materials and manufacturing techniques for heat shields that protect hypersonic vehicles in flight.

Heat protection is a critical technology to shield hypersonic vehicles from the intense heat experienced when flying at more than five times the speed of sound.

Some genes don’t stay in the same place in the genome. Sometimes called jumping genes or transposons, this genetic material can hop around and rearrange itself | Genetics And Genomics.

Some genetic sequences don’t stay in the same place in the genome. Sometimes called jumping genes or transposons, this genetic material can hop around and rearrange itself to create new sequences. Some transposons even encode for their own enzymes, and these co-called transposases can edit the genome by cutting sequences from one place and pasting them to another.

Reporting in Science, researchers have now suggested that transposable elements (TEs) can fuse with portions of existing genes that code for protein called exons, and get incorporated into genes in a process called exon shuffling to create novel genes that are functional, and express new proteins.

Scientists based at the University of Oxford as part of the Faraday Institution CATMAT project researching next-generation cathode materials have made a significant advance in understanding oxygen-redox processes involved in lithium-rich cathode materials. The paper, published in Nature Energy, proposes strategies that offer potential routes to increase the energy density of lithium-ion batteries.
