Photothermal spectroscopy measures the absorption spectra of materials by recording the wavelength-dependent heat generated upon the absorption of light. A heat sink converts the absorbed heat into a measurable quantity, such as an electrical signal in the case of thermoelectric sensors. The sensitivity of the technique critically depends on the thermal capacitance of the sensor, as this determines

Psychologist Anjila Sultan returned to the city where she grew up, after witnessing the effects of war and cultural pressures on mothers and children.

People with a specific variant had more active thymus glands, which produce immune cells that fight off infection.

Support staff should speak up more about how their skills drive scientific discovery, says glassblower Terri Adams.

Nobel laureates often receive the prize decades after their groundbreaking research — and that delay is getting longer.

A mechanism for equalizing gene expression between sexes.

When it comes to large language models, there’s one for every occasion. Find the most appropriate match for you in our AI speed-dating feature.

Respiratory syncytial virus is usually associated with babies, but the virus can also cause serious disease in older adults and people with chronic medical conditions.

Only a fraction of the planet’s surface will be habitable to mammals when the next supercontinent, Pangaea Ultima, forms.

Now, Fanglin Bao and colleagues at Purdue University and Michigan State University in the USA, have demonstrated a thermal-based sensing approach whose night-time imaging quality (depicted in the image) is more akin to daytime RGB images than to conventional night vision (Nature 619, 743–748; 2023). In their work, titled ‘Heat-assisted detection and ranging’, or HADAR, the team exploited emissivity

Light sheet microscopy offers rapid 3D imaging of biological specimens while limiting photodamage. Nature Photonics spoke with Elizabeth Hillman of Columbia University about its capabilities, promising applications and present limitations.

Listen to an audio version of a recent Nature feature.

Incoherent new climate-policy messages by Prime Minister Rishi Sunak will dissolve the UK’s climate leadership, stifle innovation’s momentum and cost consumers.

Monolithic perovskite/silicon tandem solar cells are of great appeal as they promise high power conversion efficiencies (PCEs) at affordable cost. In state-of-the-art tandems, the perovskite top cell is electrically coupled to a silicon heterojunction bottom cell via a self-assembled monolayer (SAM), anchored on a transparent conductive oxide (TCO), which enables efficient charge transfer between the

The Anopheles mosquito is one of thousands of species in which sex differences play a central role in their biology, as only females need a blood meal in order to produce eggs. Sex differentiation is regulated by sex chromosomes, but their presence creates a dosage imbalance between males (XY) and females (XX). Dosage compensation (DC) can re-equilibrate the expression of sex-chromosomal genes, but

Synthetic diamond recovers from fracture when carbon atoms on both sides of the gap form bonds with each other.

People with an abundance of specific neurons are more likely to escape cognitive decline despite having signs of Alzheimer’s in their brains.

Models trained on large data sets of seismic events can estimate the number of aftershocks better than conventional models do.

With a few modifications, ChatGPT-like models could enhance the art of identifying future laureates.

Tens of thousands of federal researchers might have to stop work on 1 October — but the shutdown’s effects could ripple well beyond government.

Nuclear resonance in scandium-45 excited by X-ray lasers could provide the basis for a highly precise and stable nuclear clock.

As flexible electronic devices continue to scale down, the extraneous response of the electrical contacts/leads to the mechanical modulation becomes non-negligible, making it increasingly difficult to accurately determine the device's intrinsic response. This poses an important challenge for dynamic characterization of flexible electronics. Here, we demonstrate a new scheme that can effectively isolate

Ozone recovery is predicted to shift westerly winds, which will reduce the amount of warm water flowing into the Southern Ocean.

Laurent Marivaux works to identify ancient mammals to understand evolutionary history in South America.

During nutrient stress, macroautophagy degrades cellular macromolecules, thereby providing biosynthetic building blocks while simultaneously remodeling the proteome1,2. While machinery responsible for initiation of macroautophagy is well characterized3,4, our understanding of the extent to which individual proteins, protein complexes and organelles are selected for autophagic degradation, and the underlying

Hours of footage of zebrafish embryos let researchers capture and study this key moment in development.

Using a metal–organic framework, researchers reduced the volume of a water-based mixture by 7%.
