Carbon-negative production of acetone and isopropanol by gas fermentation at industrial pilot scale - Nature Biotechnology

Two industrial chemicals are sustainably produced at large scale by microbial gas fermentation.

The Toll gene in Drosophila pattern formation

Toll-like receptors (TLRs) play a crucial role in innate immunity in animals. Their discovery was rewarded a Nobel Prize to Jules Hoffmann and Bruce Beutler in 2011. The name Toll stems from a Drosophila mutant that was isolated in 1980 by Eric...

Beyond sequencing: machine learning algorithms extract biology hidden in Nanopore signal data

Nanopore sequencing provides signal data corresponding to the nucleotide motifs sequenced. Through machine learning-based methods, these signals are translated into long-read sequences that overcome the read size limit of short-read sequencing....

A supernova could light up the Milky Way at any time. Astronomers will be watching

When a star from our Galactic neighbourhood explodes, it could outshine the Moon. Researchers are racing to get ready for the fireworks.

Genome Resequencing Reveals Rapid, Repeated Evolution in the Colorado Potato Beetle

Abstract. Insecticide resistance and rapid pest evolution threatens food security and the development of sustainable agricultural practices, yet the evolutionar

Structures from intact myofibrils reveal mechanism of thin filament regulation through nebulin

In situ cryo-EM structures of muscle thin filaments elucidate the structural and regulatory role of nebulin.

Palomar Survey Instrument Analyzes Impact of Starlink Satellites

A study of archival images from Zwicky Transient Facility shows an increase in satellite streaks.

Visualization Explores a Massive Star's Great Eruption

Unprecedented oil spill catches researchers in Peru off guard

Scientists are appalled at the environmental damage — and calling for the country to end its reliance on oil.

Building Structural Models of a Whole Mycoplasma Cell

Building structural models of entire cells has been a long-standing cross-discipline challenge for the research community, as it requires an unprecede…

Non-pollinator selection for a floral homeotic mutant conferring loss of nectar reward in Aquilegia coerulea

Cabin et al. present a case of natural selection in action. They show that a floral homeotic mutant of Aquilegia is under strong positive selection primarily due to reduced floral herbivory. Loss-of-function alleles at APETALA3-3 underlie the...

Nearly half of bald eagles have lead poisoning

Pollution could hamper population growth

Science and Culture: Artists join paleobotanists to bring ancient plants to life—and pique viewer interest

No one has ever seen a living Czekanowskia , an extinct gymnosperm that grew in forests across the Northern Hemisphere from around 210 through 100 million years ago. So before attempting to paint a picture of this ancient plant, Marlene Hill...

Evidence of giant asteroid strike may be buried under Wyoming

First ever detection on Earth of secondary craters points to hidden giant impact in North America

Omicron’s molecular structure could help explain its global takeover

Multiple studies are revealing why the SARS-CoV-2 variant is so transmissible, but also seems to cause milder disease.

A Billion Years Before Sex, Ancient Cells Were Equipped for It | Quanta Magazine

Molecular detective work is zeroing in on the origins of sexual reproduction. The protein tools for cell mergers seem to have long predated sex — so what were they doing?

One Year on Mars: Celebrate with the Perseverance Team – NASA’s Mars Exploration Program

Join the celebration as the Mars 2020 mission team shares their stories marking the one-year anniversary of Perseverance’s dramatic landing with events online and in-person.

Lichens Could Need More than a Million Years to Adapt to Climate Change

The composite organisms, formed from the symbiotic relationship between fungi and algae, are crucial members of myriad ecosystems

Confronting Goliath: explaining galaxies lacking dark matter

The detection of two dark-matter deficient galaxies put the standard model in crisis, immediately prompting the search for exotic alternatives. Our results show that the standard paradigm can naturally re-create these oddballs, which are formed by...
