Racing through C. elegans mitosis using cyclin B3

Written by Posted on Less than 0 min read

Racecar drivers use left-foot braking, i.e., simultaneously engaging brake and throttle, to carefully balance acceleration and traction when navigating chicanes. In this issue, Lara-Gonzalez et al. (https://doi.org/10.1083/jcb.202308034) show that C. elegans embryos employ the molecular equivalent of left-foot braking to faithfully speed through mitosis.

Caterpillars can detect their predators by the static electricity they emit

Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists at the University of Bristol have found. In the study, published today in the journal PNAS, experts showed that caterpillar hairs move in response to electric fields and are most sensitive to the frequencies that correspond to the wingbeats frequencies […]

Water fern gains more evidence as safe potential global food insecurity solution

Is the floating freshwater fern commonly called Carolina azolla the potential answer to global food insecurity or a possible threat to humanity? On the heels of a study published earlier this year by researchers at Penn State on the plant’s nutrition and digestibility, the team learned of concerns about the plant’s potential toxin content. The […]

Mobile exercise hints that recycling is in our DNA

Though it’s possible you’ll not recognize them, or have even heard of them, all through your physique, numerous microscopic machines known as spliceosomes are onerous at work. As you sit and skim, they’re faithfully and quickly placing again collectively the damaged data in your genes by eradicating sequences known as “introns” in order that your […]

Humpbacks are among animals who manufacture and wield tools

In a study published today in Royal Society Open Science, researchers at the Marine Mammal Research Program (MMRP) at UH Hawai’i Institute of Marine Biology (HIMB) and Alaska Whale Foundation (AWF) consider a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create “bubble-nets” to hunt, but they […]

Degradation of cell wall key in the spread of antibiotic resistance

A study at Umeå University, Sweden, provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria’s protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics. “You could say that we are adding a piece of the […]

Avian flu found in wastewater of 10 Texas cities through virome sequencing

Avian influenza A(H5N1) virus, which spread to cattle and infected 14 people this year, was detected using virome sequencing in the wastewater of 10 Texas cities by researchers at UTHealth Houston and Baylor College of Medicine. The virome is the collection of viruses in a sample, in this case a wastewater sample. The information was […]

These vegetation advanced in Florida hundreds of thousands of years in the past: They might be gone in many years

Scrub mints are among the many most endangered vegetation you have in all probability by no means heard of. Greater than half of the 24 species presently identified to exist are thought-about threatened or endangered on the state or federal stage, and practically all scrub mints develop in areas which are being quickly developed or […]

Building a COMPASS to navigate future pandemics

Viruses like SARS-CoV-2 don’t respect boundaries, moving between species and continents and leaving destruction as they go. Beating the next pathogen with pandemic potential means getting good at crossing borders ourselves — between fields of study, between research universities, and between scientists and the wider community. Viruses like SARS-CoV-2 don’t respect boundaries, moving between species […]
