| Bacteria for blastoff: Using microbes to make supercharged new rocket fuel Posted: 30 Jun 2022 01:00 PM PDT Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1. |
| Gemini North spies ultra-faint fossil galaxy discovered on outskirts of Andromeda Posted: 30 Jun 2022 01:00 PM PDT An unusual ultra-faint dwarf galaxy has been discovered on the outer fringes of the Andromeda Galaxy thanks to the sharp eyes of an amateur astronomer. Follow-up by professional astronomers revealed that the dwarf galaxy -- Pegasus V -- contains very few heavier elements and is likely to be a fossil of the first galaxies. |
| The hawk has landed: Braking mid-air to prioritize safety over energy or speed Posted: 30 Jun 2022 11:22 AM PDT New research using computer simulations and Hollywood-style motion capture shows how birds optimize their landing maneuvers for an accurate descent. |
| Scientists engineer synthetic DNA to study 'architect' genes Posted: 30 Jun 2022 11:21 AM PDT Researchers have created artificial Hox genes -- which plan and direct where cells go to develop tissues or organs -- using new synthetic DNA technology and genomic engineering in stem cells. Their findings confirm how clusters of Hox genes help cells to learn and remember where they are in the body. |
| Dissolving implantable device relieves pain without drugs Posted: 30 Jun 2022 11:21 AM PDT Researchers have developed a small, soft, flexible implant that relieves pain on demand and without the use of drugs. The first-of-its-kind device could provide a much-needed alternative to opioids and other highly addictive medications. It works by softly wrapping around nerves to deliver precise, targeted cooling, which numbs nerves and blocks pain signals to the brain. After the device is no longer needed, it naturally absorbs into the body -- bypassing the need for surgical extraction. |
| How pandas survive solely on bamboo: Evolutionary history Posted: 30 Jun 2022 08:44 AM PDT An ancient fossil reveals the earliest panda to survive solely on bamboo and the evolutionary history of panda's false thumbs. |
