Effective visual communication of climate change      (via sciencedaily.com)     Original source 

The consequences of a warming climate frequently dominated the news this summer, from devastating wildfires and floods to deadly heat waves across the globe. Reducing harm from climate change is a challenging endeavor, and it requires comprehensive public education. Thus, the question arises: How can climate change science be made most accessible to the general population, as well as decision-makers and educators?

Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers      (via sciencedaily.com) 

Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully produce full-length spider silk proteins using silkworms. The findings demonstrate a technique that could be used to manufacture an environmentally friendly alternative to synthetic commercial fibers such as nylon.

Fast-track strain engineering for speedy biomanufacturing      (via sciencedaily.com) 

Using engineered microbes as microscopic factories has given the world steady sources of life-saving drugs, revolutionized the food industry, and allowed us to make sustainable versions of valuable chemicals previously made from petroleum. But behind each biomanufactured product on the market today is the investment of years of work and many millions of dollars in research and development funding. Scientists want to help the burgeoning industry reach new heights by accelerating and streamlining the process of engineering microbes to produce important compounds with commercial-ready efficiency.

Laser-based ice-core sampling for studying climate change      (via sciencedaily.com) 

Researchers have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution and is expected to help reconstruct continuous annual temperature changes that occurred thousands to hundreds of thousands of years ago, which will help scientists understand climate change in the past and present.

Glacier Loss Day indi­cates record break­ing glacier melt      (via sciencedaily.com)     Original source 

In the summer of 2022, one of Tyrol's largest glaciers experienced its most significant loss of mass on record. Last year, the Hintereisferner in Tyrol, Austria, reached its Glacier Loss Day (GLD) earlier than ever before. The GLD serves as an indicator of a glacier's health throughout the year, similar to how the Earth Overshoot Day measures Earth's resource consumption.

Tiny sea creatures reveal the ancient origins of neurons      (via sciencedaily.com)     Original source 

A new study sheds new light on the origins of modern brain cells. Researchers find evidence that specialized secretory cells found in placozoans, tiny sea creatures the size of a grain of sand, have many similarities to the neuron, such as the genes required to create a partial synapse. From an evolutionary point of view, early neurons might have started as something like these cells, eventually gaining the ability to create a complete synapse, form axons and dendrites and create ion channels that generate fast electrical signals -- innovations which gave rise to the neuron in more complex animals such as jellyfish. Though the complete story of how the first neuron appeared remains to be told, the study demonstrates that the basic building blocks for our brain cells were forming in the ancestors of placozoans grazing inconspicuously in the shallow seas of Earth around 800 million years ago.

RNA for the first time recovered from an extinct species      (via sciencedaily.com)     Original source 

A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.

Tracking down the formation of cardenolides in plants      (via sciencedaily.com)     Original source 

Scientists are investigating the previously largely unknown biosynthetic pathway that leads to the formation of cardenolides in plants. In a new study, they present two enzymes from the CYP87A family as key enzymes that catalyze the formation of pregnenolone, the precursor for the biosynthesis of plant steroids, in two different plant families. The discovery of such enzymes should help to develop platforms for the cheap and sustainable production of high quality steroid compounds for medical use.

Genome editing: Reducing off-target mutations in DNA      (via sciencedaily.com)     Original source 

Researchers have developed a novel genome editing technique known as NICER, which results in significantly fewer off-target mutations than CRISPR/Cas9 editing. The technique uses a different type of enzyme that makes single-stranded 'nicks' in the DNA. Repair of these nicks is more efficient and accurate than repair of double-strand breaks caused by the current CRISPR/Cas9 editing. This technique represents a novel approach for the treatment of genetic diseases caused by heterozygous mutations.
