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.

Researchers propose widespread banking of stool samples for fecal transplants later in life

Posted: 30 Jun 2022 08:45 AM PDT

Changes in the way that humans live and eat have resulted in tremendous alterations in the gut microbiome, especially over the past few decades. These changes have been linked to increased rates of asthma, allergies, diseases of the digestive system, type 2 diabetes, and other conditions. Scientists propose that we can combat these trends by having individuals bank samples of their own gut microbiota when they are young and healthy for potential use later in life in an autologous fecal microbiota transplant (FMT).

How pandas survive solely on bamboo: Evolutionary history

Winemaking practices in coastal Italy during the Roman period involved using native grapes for making wine in jars waterproofed with imported tar pitch, according to a new study.

Tracking a levitated nanoparticle with a mirror

Posted: 29 Jun 2022 07:22 AM PDT

Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Now, researchers have demonstrated a new method for optical interferometry in which light scattered by a particle is reflected by a mirror. This opens up new possibilities for using levitated particles as sensors, in particular, in quantum regimes.
