Superconductor's magnetic persona unmasked

New experiments by US, Chinese and European physicists have found iron selenide's magnetic properties are highly anisotropic, like other iron superconductors. The material's structure and electronic behavior are surprisingly similar to those of other iron-based superconductors.

SCAI releases multi-society endorsed consensus on the classification stages of cardiogenic shock

A new five-stage system defines cardiogenic shock based on narrative patient descriptions, physical findings, and biochemical/hemodynamic markers to facilitate rapid assessment and communication between providers. The consensus aims to standardize vocabulary, recognize risk for adverse outcomes, and inform interventions.

Resilience of Yellowstone's forests tested by unprecedented fire

A recent study found that Yellowstone's re-burned forests have a six-fold decline in lodgepole pine tree seedlings and lost significant carbon storage capacity after experiencing two consecutive fires within fewer than 30 years. The researchers estimate it would take over 150 years for the forest to recover its lost carbon.

Circadian mechanism may not be driver behind compound linked to obesity and diabetes

A Penn Medicine study found that compound SR9009 can affect cell growth and metabolic function without the presence of protein REV-ERB, challenging previous understanding of its effects on obesity and diabetes. The research has significant implications for researchers and the general public.

Size is everything

A new method has been developed to predict the vulnerability of ecosystems, focusing on predators' body mass and prey characteristics. The approach enables researchers to determine habitat structure and stability without comprehensive data on all organisms.

Giving rural Indians what they want increases demand for cookstoves

A new study led by Duke University researchers found that adopting common business practices can increase the demand for improved cookstoves in rural India. The study showed a significant increase in adoption rates, with nearly half of households purchasing stoves in intervention areas compared to zero purchases in control villages.

Hyperspectral camera captures wealth of data in an instant

Rice University's NASA-funded TuLIPSS project develops a portable spectrometer that can capture hyperspectral data instantly, unlike current systems that scan line-by-line. The device, called TuLIPSS, uses optical fibers to deliver image components to a detector and customize the balance of spectral and spatial data.

Expert judgement provides better understanding of the effect of melting ice sheets

An international team of scientists used structured expert judgment to estimate plausible ranges for future sea level rise from melting ice sheets. Their findings suggest that coastal communities should not rule out the possibility of 21st-century SLR in excess of two metres when developing adaptation strategies.

Synthesis of helical ladder polymers

Scientists have successfully synthesized helical ladder polymers using a novel electrophilic aromatic substitution method. The resulting molecules exhibit well-defined right-handed helical geometry and can be modified to create nanoscale architectures for various applications.
