CAPSTONE, the pathfinder for NASA’s lunar outpost, will test an orbit around the Moon that has never been flown before.
Read MoreNew PET-like plastic made directly from waste biomass
It is becoming increasingly obvious that moving away from fossil fuels and avoiding the accumulation of plastics in the environment are key to addressing the challenge of climate change. In that vein, there are considerable efforts to develop degradable or recyclable polymers made from non-edible plant material referred to as “lignocellulosic biomass.”
Read MoreClimate change could lead to a dramatic temperature-linked decrease in essential omega-3 fatty acids
The effects of global climate change already are resulting in the loss of sea ice, accelerated sea level rise, and longer and more intense heat waves, among other threats.
Read MoreCreating heat-tolerant, stable boron nitride nanotube fibers
A Rice University team led by professors Matteo Pasquali and Angel Martí has simplified handling of the highly valuable nanotubes to make them more suitable for large-scale applications, including aerospace, electronics and energy-efficient materials.
Read MoreStructure-property relationships in nanoporous and amorphous iridium oxides
South Korean-based researchers have used first-principles quantum mechanical simulations to better understand the structure-property relationships in various polymorphic phases of iridium oxides to elucidate their outstanding performance in catalyzing the oxygen evolution reaction (OER). The OER is an important half-cell reaction where water is catalytically split to evolve oxygen. However, due to the intrinsic sluggish […]
Read MoreFunny Titles, And Not So Much
Let’s turn to slightly less fraught subjects than Long Covid, failure rates for vital clinical trials, dread diseases and so on. You know, the usual menu of cheerfulness around here. Instead, let’s look at a topic whose importance has somehow been obscured until now: does giving your research paper a funny title lead to it […]
Read MoreThis giant bacterium is the largest one found yet
There’s a new record holder for biggest bacterium — and you don’t need a microscope to see it. The newfound species, Thiomargarita magnifica, is roughly a centimeter long, and its cells are surprisingly complex, researchers report in the June 24 Science. The bacterial behemoth is roughly the size and shape of a human eyelash, marine […]

Vampire squid are gentle blobs. But this ancestor was a fierce hunter
Despite the scary name, modern vampire squid are docile denizens of the deep sea — but their Jurassic ancestors may have been a lot fiercer. Analyses of fossilized soft tissue from three 164-million-year-old specimens of Vampyronassa rhodanica suggest that the ancient cephalopods had some powerful weapons, researchers say June 23 in Scientific Reports. Unlike its […]

Fierce fighting in the Donbas region has already resulted in the destruction of a number of chemical plants
Read MoreGiant bacteria found in Guadeloupe mangroves challenge traditional concepts
Researchers describe the morphological and genomic features of a ”macro’ microbe’ — a giant filamentous bacterium composed of a single cell discovered in the mangroves of Guadeloupe. Using various microscopy techniques, the team also observed novel, membrane-bound compartments that contain DNA clusters dubbed ‘pepins.’
Read MoreHumans can’t, but turtles can: Reduce weakening and deterioration with age
Evolutionary theories of ageing predict that all living organisms weaken and deteriorate with age (a process known as senescence) — and eventually die. Now, researchers show that certain animal species, such as turtles (including tortoises) may exhibit slower or even absent senescence when their living conditions improve.
