The seven rocky planets of TRAPPIST-1 seem to have very similar compositions

This illustration shows three possible interiors of the seven rocky exoplanets in the TRAPPIST-1 system, based on precision measurements of the planet densities. Overall the TRAPPIST-1 worlds have remarkably similar densities, which suggests they may share the same ratio of common planet-forming elements. The planet densities are slightly lower than that of Earth or Venus, […]

No more needles for diagnostic tests? Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells — ScienceDaily

Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen […]

University of Cincinnati research unveils possible new combo therapy for head and neck cancer

Fungi strengthen plants to fend off aphids

Credit: CC0 Public Domain Researchers at the University of Copenhagen have demonstrated that unique fungi strengthen the immune systems of wheat and bean plants against aphids. Fungi enter and influence the amount of a plant’s own defenses, resulting in fewer aphids. The results could serve to reduce agricultural insecticide use and bring Denmark a step […]

Single atoms as a catalyst: Surprising effects ensue

Catalysts are getting smaller – ‘single-atom’ catalysts are the logical end point of this downsizing. However, individual atoms can no longer be described using the rules developed from larger pieces of metal, so the rules used to predict which metals will be good catalysts must be revamped – this has now been achieved. As it […]

Aging dams pose growing threat: UN

Cover of the UNU-INWEH report. Credit: UNU-INWEH By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the 20th century, many of them already operating at or beyond their design life, according to a UN University analysis. The report, “Ageing water infrastructure: An emerging global risk,” by […]

A desalination membrane laminated with nanosheets featuring 2D nanochannels — ScienceDaily

Professor MATSUYAMA Hideto’s research group at Kobe University’s Research Center for Membrane and Film Technology has successfully developed a new desalination membrane. They achieved this by laminating a two-dimensional carbon material (*1) on to the surface of a porous polymer membrane (*2). Desalination (*3) membranes are used to produce freshwater from seawater. In order to […]

Horseshoe crabs are critical to the biotech industry

The Atlantic Horseshoe crab is a 500-million-year-old species with ten eyes, six tails, and one body full of blue blood. Even though it sounds like this creature was pulled straight out of a science fiction novel, the horseshoe crab plays an integral role in the modern biomedical industry. Horseshoe crab blood gets its striking blue […]

How to knit your own Bernie mittens

If you want to make cozy, patterned mittens, you’ve got to start with cozy, single-colored mittens. (Sandra Gutierrez G./) Knitting anything that is not a scarf or a beanie can be utterly intimidating, but I swear to you—mittens are not as hard as you think. This project is fast and simple, though it does require […]
