At least one out of four white dwarfs (WDs) will end its life as a magnetic star, and therefore magnetic fields are an essential component of WD physics. New insights into the magnetism of degenerate stars from a recent analysis of a volume-limited sample of WDs have provided the best evidence obtained so far of how the frequency of magnetism in WDs correlates with age. This could help to explain

Oceans play a key role in the global carbon dioxide balance. This is because billions of tiny algae live there, absorbing carbon dioxide through photosynthesis and incorporating it into their biomass. When these algae die, they trickle down—along with the excretions of microscopic creatures that feed on them—as "marine snow" into deeper zones. About one percent of their carbon dioxide then lies bu
Children learn science in nature play long before they get to school classrooms and labs2d

Bacterial rhamnolipids and their 3-hydroxyalkanoate precursors activate Arabidopsis innate immunity through two independent mechanisms [Plant Biology]1d
Plant innate immunity is activated upon perception of invasion pattern molecules by plant cell-surface immune receptors. Several bacteria of the genera Pseudomonas and Burkholderia produce rhamnolipids (RLs) from l-rhamnose and (R)-3-hydroxyalkanoate precursors (HAAs). RL and HAA secretion is required to modulate bacterial surface motility, biofilm development, and thus successful colonization…

Nobody knows exactly how old they can get, and some experts have estimated they could live on the ocean floor for as long as a century or more. Until now, a lobster's age has usually been estimated using its size – but this is inaccurate as individual lobsters grow
Wide heads help sperm swim together1d
Researchers used machine learning to discover that sperm with a wide head relative to length are more likely to clump together and swim collectively, a rare behavior that sometimes helps them reach an egg faster. The study provides a new method for understanding how form and function are related in cells with complex behaviors in all animals, including humans.

However, how do these recollections translate onto the story of who we are that we tell ourselves every day?
Team proposes microprinting a fiber-tip polymer clamped-beam probe for high-sensitivity nanoforce measurements2d
The control and measurement of asserted forces on small objects are frequently seen in micromanipulation, material science, and biological and medical applications. Researchers in China have proposed for the first time the microprinting of a novel fiber-tip-polymer clamped-beam probe micro-force sensor for the examination of biological samples. This approach opens new avenues towards the realizati

Dim light in the evening causes coordinated realignment of circadian rhythms, sleep, and short-term memory [Neuroscience]2d
Light provides the primary signal for entraining circadian rhythms to the day/night cycle. In addition to rods and cones, the retina contains a small population of photosensitive retinal ganglion cells (pRGCs) expressing the photopigment melanopsin (OPN4). Concerns have been raised that exposure to dim artificial lighting in the evening (DLE)…
Scene statistics and noise determine the relative arrangement of receptive field mosaics [Physics]2d

Valveless microliter combustion for densely packed arrays of powerful soft actuators [Engineering]2d
Existing tactile stimulation technologies powered by small actuators offer low-resolution stimuli compared to the enormous mechanoreceptor density of human skin. Arrays of soft pneumatic actuators initially show promise as small-resolution (1- to 3-mm diameter), highly conformable tactile display strategies yet ultimately fail because of their need for valves bulkier than…
A steady-state N balance approach for sustainable smallholder farming [Agricultural Sciences]2d
Hundreds of millions of smallholders in emerging countries substantially overuse nitrogen (N) fertilizers, driving local environmental pollution and global climate change. Despite local demonstration-scale successes, widespread mobilization of smallholders to adopt precise N management practices remains a challenge, largely due to associated high costs and complicated sampling and calculations.

Self-catalytic growth of one-dimensional materials within dislocations in gold [Chemistry]2d
Dislocations in metals affect their properties on the macro- and the microscales. For example, they increase a metal's hardness and strength. Dislocation outcrops exist on the surfaces of such metals, and atoms in the proximity of these outcrops are more loosely bonded, facilitating local chemical corrosion and reactivity. In this…
Nanosecond heme-to-heme electron transfer rates in a multiheme cytochrome nanowire reported by a spectrally unique His/Met-ligated heme [Biophysics and Computational Biology]2d
Proteins achieve efficient energy storage and conversion through electron transfer along a series of redox cofactors. Multiheme cytochromes are notable examples. These proteins transfer electrons over distance scales of several nanometers to >10 μm and in so doing they couple cellular metabolism with extracellular redox partners including electrodes. Here, we…
Can we get human nature right? [Psychological and Cognitive Sciences]2d
Few questions in science are as controversial as human nature. At stake is whether our basic concepts and emotions are all learned from experience, or whether some are innate.

The conserved fertility factor SPACA4/Bouncer has divergent modes of action in vertebrate fertilization [Genetics]2d
Fertilization is the fundamental process that initiates the development of a new individual in all sexually reproducing species.

What we talk about when we talk about colors [Psychological and Cognitive Sciences]2d
Names for colors vary widely across languages, but color categories are remarkably consistent. Shared mechanisms of color perception help explain consistent partitions of visible light into discrete color vocabularies.
