Columbia researchers take the temperature of integrated photonics

Researchers at Columbia University School of Engineering and Applied Science have discovered that a thin-film metallic resistor used to thermally tune photonic devices can also measure temperature. This finding may help integrated photonics reach its full potential by eliminating the need for bulky external temperature sensors.

When irrigation backfires

Irrigation expansion has increased water losses from land through evapotranspiration, depleting freshwater resources in hot spot areas. In regions like South Asia, climate change and irrigation exacerbate humid-heat stress risks.

Sun: First glimpse of polar magnetic field in motion

Researchers analyzed data from Solar Orbiter's PHI and EUI instruments to study the Sun's supergranulation and magnetic network at the south pole. The findings show that the magnetic field drifts towards the poles faster than expected, providing important clues about the Sun's global plasma and magnetic field circulation.

The “blue forest”* in figures: first global inventory of carbon stored by seagrass meadows

Seagrass meadows, such as Posidonia, accumulate around 1.5 tonnes of carbon per hectare in the living parts of plants and fix nearly 7 tonnes each year. The global assessment confirms that these ecosystems play a key role in absorbing atmospheric CO₂, transforming it, and retaining it.

The escape room challenge: How one person’s narcissism can undermine a whole team

A new study found that individuals with narcissistic rivalry tendencies are more likely to damage team dynamics, leading to lower cohesion and poorer performance. In contrast, narcissistic admiration didn't seem to impact performance, but those individuals were increasingly viewed as less hardworking and arrogant by their teammates.

High risk of suicide after involuntary psychiatric care

A nationwide study found that involuntary psychiatric patients have a significantly higher risk of suicide, particularly during the first month after discharge. The risk is elevated for several years and is associated with factors such as age, diagnosis, and previous self-harm.

Two small changes, that may transform agriculture

A breakthrough study from Aarhus University identified two amino acid changes that allow plants to switch off their immune system and form symbiosis with nitrogen-fixing bacteria. This discovery could lead to breeding crops like wheat, barley, and maize that can fix nitrogen themselves, reducing the need for artificial fertilizer.

A new NIH grant will support the development of stronger and healthier parent-child relationships among parents in recovery, critical for sustained recovery and positive child development. The project aims to empower peer recovery specialists with tools to deliver meaningful parenting support alongside recovery services.

Thinning turned an upland forest into a temporary carbon source and made a peatland forest an even stronger carbon source

Research at the University of Helsinki reveals that forest thinning can temporarily boost carbon storage in upland forests, while drained peatlands become stronger net carbon sources due to slower tree growth and increased decomposition. The study highlights the importance of adapting management practices to different forest types.
