Physical effect also valid in the quantum world

Physicists at the University of Bonn have experimentally proven the applicability of the fluctuation-dissipation theorem to Bose-Einstein condensates made of photons. The study reveals a direct relationship between fluctuation and sensitivity, enabling precise temperature determination in complex photonic systems.

Nab-paclitaxel does not extend biliary tract cancer survival, but may benefit some

A phase 3 trial found that adding nab-paclitaxel to a standard gemcitabine plus cisplatin regimen did not significantly extend median overall survival for patients with advanced biliary tract cancers, but provided benefits for subsets of patients. The treatment also showed improved response rates and progression-free survival times.

Towards highly conducting molecular materials with a partially oxidized organic neutral molecule

A team of researchers from Japan has developed a single purely organic neutral molecule with an incomplete oxidation state for the first time. The new molecule exhibits multi-step phase transitions and crossover caused by intra- and intermolecular electronic interactions, leading to unique strongly correlated electron properties.

Why Asia-Pacific tropical seas flourish with marine life

A new study reveals that transient wind events trigger significant phytoplankton blooms near tropical reef islands, creating a large network of marine ecosystems. This process, driven by coastal winds, fuels the production of phytoplankton and supports critical feeding habitats for migratory marine species.

Relationship between superconductivity and strange-metal state in FeSe revealed by ionic-liquid gating

Scientists have discovered a quadratic relationship between the coefficient of T-linear resistivity and transition temperature in FeSe, indicating that spin fluctuations may play a common role in unconventional superconductors. This finding provides insight into high-temperature superconductivity.

DNA from domesticated chickens is tainting genomes of wild red junglefowl

A recent study found that DNA from domesticated chickens has been introgressing into the genomes of wild red junglefowl, leading to a loss of genetic diversity. The researchers estimate that wild birds have inherited 20-50% of their genomes from domestic chickens, which could make them less resilient to environmental changes.

Mother’s health and lifestyle during pregnancy shape neurodevelopment of 2-year-old children

A new study conducted at the University of Turku found that maternal gestational diabetes mellitus may have unfavourable effects on the neurodevelopment of 2-year-old children. A healthy diet during pregnancy supports child's neurodevelopment, while higher maternal body fat percentage is associated with weaker cognitive and motor skills.

Paper: California's proposal to manufacture insulin could curb prices, improve public health

A new paper by a University of Illinois legal scholar suggests that California's CalRx Biosimilar Insulin Initiative could lower insulin prices, saving uninsured patients up to $4,000 per year. The proposal faces regulatory and logistical challenges, including FDA approval and state budgeting issues.

Scientists advise a major shift in chemicals management in the U.S. and Canada

Scientists propose an 'essential use approach' to eliminate harmful chemicals from daily use and exposure, benefiting public health and the environment. This approach advocates for restricting the use of chemicals only where necessary for health or societal functioning, with feasible alternatives available.

Active matter theory explains fire-ant group behavior

Fire ants exhibit activity cycles and waves that propagate upwards in high-density conditions, driven by social attraction and collective motion. The study reveals the importance of density in determining these behaviors, which are similar to those observed in flocks of birds and schools of fish.
