Decades-long study reveals how blood cancers evolve and why some patients' disease worsens

Researchers tracked 30 patients with chronic blood cancers over time, finding that those whose disease remained stable had 'steady' blood cells without additional mutations. Conversely, those with progressing diseases developed changes in DNA years before symptoms worsened. This challenges current views on diagnosing patients without t...

Nordic Seas Overturning Circulation strengthens as Atlantic Meridional Overturning Circulation weakens, new study

The Nordic Seas Overturning Circulation (NOC) has strengthened while the Atlantic Meridional Overturning Circulation (AMOC) has weakened due to global warming. Models project a slight increase in NOC's density-driven mechanism, which counterintuitively strengthens the northern branch despite AMOC weakening.

Unexpectedly attractive molecules

Researchers at Ehime University discovered a π-stacked dimer of positively charged antiaromatic molecules stabilized upon stacking, contrary to their inherent instability. The findings suggest that intermolecular stacking can partially attenuate the intrinsic instability characteristic of antiaromatic molecules.

Physicists refute famous 2025 study claiming daylight saving time poses severe health risks

Professors José María Martín-Olalla and Jorge Mira Pérez refute the 2025 study linking Daylight Saving Time to negative health outcomes, citing a critical error in methodology. The original study's conclusions were based on an incorrect calculation of daily readjustments, which resulted in a zero annual cumulative total.

Compact and programmable large-scale optical processor in free space

Scientists have demonstrated a reconfigurable photonic circuit implementing wide class of complex unitary transformations via optical manipulation at three layers only. The platform enables flexible access to many co-propagating structured modes, making it suitable for applications in communication, information processing, and simulation.

New research approach improves the flavor stability of flaxseed oil and extends its shelf life

A new study removes bitter-tasting compounds from flaxseed oil, preserving its health-beneficial fatty acids and extending its shelf life. The approach uses bleaching earth to selectively reduce cyclolinopeptides, resulting in a flavor-stable oil that remains milder for longer.

Squeezing a Kondo ferromagnet reveals superconductivity beyond a magnetic quantum critical point

A team of scientists has found that applying pressure to the heavy-fermion ferromagnet Ce5CoGe2 reveals superconductivity above a magnetic quantum critical point, defying typical expectations. The unusual phase diagram suggests that other ingredients beyond magnetic fluctuations may drive superconductivity in this material.

AACR: New platform uses machine learning to predict responses in patients with lung cancer

Researchers developed an AI model called Path-IO that uses machine learning to predict responses to immunotherapy for patients with metastatic non-small cell lung cancer. The model accurately stratified patients into high-risk and low-risk groups, with patients in the high-risk group having double the risk of death or disease progression.

Using a new online mental health tool just once boosts teenagers’ hope and emotional wellbeing

A digital single-session intervention (SSI) has been shown to meaningfully improve young people's sense of hope and control over their lives. The tool provides short, accessible and evidence-based psychological support and wellbeing activities, increasing feelings of hope and self-agency while reducing feelings of being out of control.

New publication about the influence of Southern Hemisphere waters on the Indonesian Throughflow

A new study finds that water masses from the Southern Hemisphere have been a major contributor to the Indonesian Throughflow for over 800,000 years. The researchers measured nitrogen isotopes in sediment cores and found a remarkable long-term stability of the nitrogen cycle along the equatorial Pacific.

Cocaine pollution alters salmon behaviour in the wild

A recent study by researchers at Griffith University and others found that exposure to cocaine contamination altered the movement patterns of Atlantic salmon in Lake Vättern, Sweden. Fish exposed to benzoylecgonine swam up to 1.9 times farther than unexposed fish, with dispersal distances reaching up to 12.3km.
