Research has identified a promising path to developing therapies to treat esophageal tumors — a form of cancer that not only is among the most deadly, but also has been occurring at increasing rates over the past decade.

1 in 5 adult female white-necked jacobin hummingbirds look like males. New research shows that this is a rare case of ‘deceptive mimicry’ within a species: Females with male-like plumage are trying to pass themselves off as males, and as a result recei…

A new study has found that as temperatures rise, the window of opportunity to maximize the use of biomass from plants, wood and waste as a renewable energy source and an alternative to petrochemicals is closing.

Researchers have uncovered a novel mechanism by which protein arginine deiminase 4 (PAD4) in neutrophils promotes cancer progression.

In a simulation study using the latest U.S. statistics for stage 1 hypertension, researchers found that lifestyle changes to reduce systolic blood pressure to below 130 mm Hg may prevent 26,000 heart attacks and strokes and reduce health care costs ove…

A study of adolescent eating habits found that certain ultra-processed foods, such as candy, prepackaged pastries and frozen desserts, may act as a ‘gateway’ and lead to increased intake of other unhealthy foods. 43% of the adolescents estimated that t…

A new study in mice found that hypertension may be linked to significant bone loss. Bone quality in young mice with high blood pressure was similar to the bones of older mice without high blood pressure, suggesting that the effects of hypertension on b…

Scientists have quantified the glacier mass loss on the Kamchatka Peninsula; the accelerated loss in the region since the turn of the millennium is likely to increase in the short term.

Crucial to our everyday use the Li-ion battery can be found everywhere. Research has now resulted in a hybrid electrolyte that is both more stable while also retaining excellent conductivity. This will pave the way to a safer polymeric solid electrolyt…

Researchers examined various markers in the urine of wild bonobos (Pan paniscus). The researchers found that the birth of a second young animal resulted in the older sibling in a five-fold increase in the stress hormone cortisol and a reduced immune re…

If you spend 30 minutes less on social media every day and engage in physical activity instead, you do a lot to improve your mental health, according to a new study. Participants who followed this advice for two weeks felt happier, more satisfied, less…

Detailed characterization of human pancreatic islets is key to elucidate the pathophysiology of all forms of diabetes mellitus, including its most common form known as type 2 diabetes (T2D). However, access to pancreatic islets is limited and pancreati…

Of all the oceans on Earth, the Southern Ocean does the lion’s share at slowing the pace of climate change by absorbing most of the excess heat trapped in the planet’s atmosphere, say scientists.

Monitoring of viruses in wastewater enables the course of a pandemic and its burdens on various parts of the health-care sector to be predicted, independently from official public testing capacity and scope for infection tracking.

A new neuroscience study shows how stimuli and states such as smells, stressors and satiety converge in an olfactory neuron to guide food-seeking behavior in the model organism C. elegans.

‘You’re so smart!’ — This encouraging response may actually do more harm than good to children’s math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities …

Astronomers have just announced the discovery of two ‘super-Earth’ planets orbiting LP 890-9, a small, cool star located about 100 light-years from Earth.

Researchers estimate that more than 1.1 million sea turtles have been illegally killed and, in some cases, trafficked between 1990 and 2020. Even with existing laws prohibiting their capture and use, as many as 44,000 sea turtles were exploited each ye…

Results of a small but unique research study suggest that low-dose ketamine is generally safe, well-tolerated and effective to treat clinical symptoms in children diagnosed with ADNP syndrome (also known as Helsmoortel-VanDerAa syndrome), a rare neurod…

Using a mouse model, researchers describe a process in which affected neurons switch expression of neurotransmitters in response to day length stimuli, triggering related behavioral changes.
