Read MoreTyrosine chassis for sustainable, high-yield production of useful compounds in yeast smart cells
Kobe University researchers have successfully developed a tyrosine chassis (a strain of microorganism with high tyrosine productivity) in the yeast Pichia pastoris through rational engineering. In addition they used this tyrosine chassis to develop smart cells that can produce the plant-derived compounds resveratrol, naringenin, norcoclaurine, and reticuline respectively. These compounds have a wide range of […]
Read MoreCan we make graphite from coal? Researchers start by finding new carbon solid
As the world’s appetite for carbon-based materials like graphite increases, Ohio University researchers presented evidence this week for a new carbon solid they named “amorphous graphite.”

A few weeks ago, I was obsessed with my nose and throat. I was on a trip to Seattle to speak at a small, masks-required virology meeting about being a journalist during a pandemic. I went to graduate school there, so I was thrilled to see old friends and colleagues. But the irony that I […]
Read MoreScientists created ‘smoke rings’ of light
Smoke rings are being seen in a new light. Doughnut-shaped structures called vortex rings are sometimes seen swirling through fluids. Smokers can form them with their mouths, volcanoes can spit them out during eruptions and dolphins can blow them as bubble rings. Now, scientists can create the rings with light. A standard vortex is an […]
Read MoreThe Earth moves far under our feet: A new study shows the inner core oscillates
Scientists have found evidence that the Earth’s inner core oscillates, contradicting previously accepted models that posited it consistently rotates at a faster rate than the planet’s surface.
Read MoreAstronomers may have detected a ‘dark’ free-floating black hole
Astronomers have discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object’s strong gravitational field — so-called gravitational microlensing.
