Eco-glue can replace harmful adhesives in wood construction
Researchers at Aalto University have developed a bio-based adhesive that can replace formaldehyde-containing adhesives in wood construction. The main raw material in the new adhesive is lignin, a structural component of wood and a by-product of the pulp industry that is usually burned after wood is processed. As an alternative to formaldehyde, lignin offers a healthier and more carbon-friendly way

Tracking invasive plants from space
Invasive plant species do more than harm agriculture and native species as they reshape landscapes. They also cause economic losses of more than $20 billion annually in the U.S. alone. Identifying where and how quickly invasive plants are spreading is critical to fighting an invasion.

Analyses of heat shock transcription factors and database construction based on whole-genome genes in plants
The heat shock transcription factors (Hsfs) are members of a key transcription factor gene family that responds to heat stress and plays an important role in heat resistance. Previous reports have shown that Hsf family genes contain several conserved domains. At the N terminus is a DNA-binding domain (DBD) that can recognize promoter elements of heat-responsive genes.

Improving the estimation of microplastic concentrations in freshwater environments
The extent of plastic pollution remains largely hidden from view in the form of microplastics (MPs): plastic particles with diameters less than 5 mm. Since plastics are slow to degrade, they fragment into tiny particles that end up contaminating entire ecosystems. In the years since their discovery in the early 1970s, MPs have become a ubiquitous and global concern. MPs are found in land, air, wat

The Camp Fire Teens Are Adults Now
Katie Elder got just a few normal months of high school before the fire came. It was early November of 2018, her freshman year. Her mom woke her up around 7 a.m., and Katie began to get ready for what she thought would be a normal school day. Then they stepped outside and saw an orange sky. She felt the wind gust. "We've lived in California all our lives. We've been around fires," the now-18-year

Social media is polluting society. Moderation alone won't fix the problem
We all want to be able to speak our minds online—to be heard by our friends and talk (back) to our opponents. At the same time, we don't want to be exposed to speech that is inappropriate or crosses a line. Technology companies address this conundrum by setting standards for free speech, a practice protected under federal law. They hire in-house moderators to examine individual pieces of content

The cognitive dissonance of watching the end of Roe unfold online
I learned on a liveblog that I had lost the right to have an abortion. When the United States Supreme Court reversed Roe v. Wade on the morning of June 24, 2022, I was one of the nearly 16,000 people reading SCOTUSblog, a news site launched 20 years ago, which has no official relationship with the Supreme Court, which has never been granted press credentials to the court, and which won a Peabody

Nested order-disorder framework containing a crystalline matrix with self-filled amorphous-like innards
Nature Communications, Published online: 09 August 2022; doi:10.1038/s41467-022-32419-5 The synthesis and characterization of new crystalline-amorphous hybrid materials is challenging. Here, the authors report the preparation of a nested order-disorder framework by applying high pressure to a nested copper chalcogenide Cu12Sb4S13.

The big idea: are we living in a simulation?
Could the universe be an elaborate game constructed by bored aliens? Elon Musk thinks you don't exist. But it's nothing personal: he thinks he doesn't exist either. At least, not in the normal sense of existing. Instead we are just immaterial software constructs running on a gigantic alien computer simulation. Musk has stated that the odds are billions to one that we are actually living in "base

Overlooking Skin Cancer in People With Dark Skin
Given the known disparities in outcomes, experts say two areas of research are needed: studying educational initiatives to see if awareness might lead to earlier diagnosis; and determining risk factors in patients with dark skin, especially factors leading to melanoma in places less exposed to the sun.

Shielded soft force sensors
Nature Communications, Published online: 09 August 2022; doi:10.1038/s41467-022-32391-0 Capacitive soft force sensors require electrical shielding from electromagnetic interference, but this shielding can mess with the effectiveness of the sensing electrodes. Here, Aksoy et al. solve this problem by patterning the central sensing elastomer layer to control its compressibility.

From the archive: Why are climate and conservation scientists taking to the streets? – podcast
In early April this year, the Intergovernmental Panel on Climate Change released a new report giving the world just 30 months to get greenhouse gas emissions falling. Beyond that, we'll have missed our chance of limiting global heating to 1.5C. As this summer of heatwaves, droughts, wildfires and floods prove, going much above 1.5C will have truly devastating consequences for us and the planet. W

Traces of 2010 Deepwater Horizon oil spill are still detectable in 2020
Small amounts of highly weathered oil residues from the 2010 Deepwater Horizon disaster were still present in the surroundings ten years later, shows a new report. Crude oil is a complex mixture with many components that undergo chemical reactions in the environment. These transformed chemicals, as well as longer persisting oil products, can impact local ecosystems and a better understanding of th
