For The Better

Up to an hour after their hearts had stopped, some patients revived by cardiopulmonary resuscitation (CPR) had clear memories afterward of experiencing death and had brain patterns while unconscious linked to thought and memory, report investigators.

Neurotypical humans readily optimize performance in ‘reversal learning’ games, but while mice learn the winning strategy, they refuse to commit to it, a new study shows. The research provides a mathematical way to track the rodents’ more mixed tactics.

A study led by obstetricians has shown that a new device can rapidly control postpartum hemorrhage, a major cause of severe maternal morbidity and death, in a wide range of patients.

Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. This image of HH 211 from NASA’s Jame…

With Style2Fab, makers can rapidly customize models of 3D-printable objects, such as assistive devices, without hampering their functionality.

Flexible thin-film electrodes placed directly on brain tissue show promise for the diagnosis and treatment of epilepsy. Thanks to an innovative yet straightforward design, these durable electrodes accurately match the mechanical properties of brain tis…

New research has shown that boosting the ‘warm glow’ feeling that people experience after giving blood significantly increases repeat blood donations, which are essential for the effective running of any health service.

Researchers have genetically engineered a marine microorganism to break down plastic in salt water. Specifically, the modified organism can break down polyethylene terephthalate (PET), a plastic used in everything from water bottles to clothing that is…

A study reveals a possible explanation for why checkpoint blockade inhibitors don’t work well for some patients whose tumors have a high mutational burden.

R esearchers created a machine learning algorithm using computational topology that profiles shapes and spatial patterns in embryos to study how these cells organize themselves into tissue-like architectures. In a new study, they take that system to th…

Researchers provide essential insights on the molecular activation of the MAP kinase p38?, the final switch triggering the inflammatory response. Inflammation is a cellular coping mechanism when confronted with stress, such as an infection. However, to…

Researchers have characterized a specialized type of immune cell, which plays a key role in protecting and repairing the cells in the healthy human gut.

With research showing that the SDGs have had little political impact, the September 18-19 UN SDG Summit must pave the way for four major changes in how the SDGs are implemented and governed globally, argues an international group of sustainability expe…

Researchers have identified a backup mechanism of protein quality control which prevents the toxic effects of protein aggregation in specific tissues when normal methods of molecular monitoring fail. By understanding how different tissues tackle protei…

The better a songbird is at working its way around obstacles to retrieve a snack, the more complex its vocal learning ability will be.

Lab-based studies reveal how carbon atoms diffuse on the surface of interstellar ice grains to form complex organic compounds, crucial to reveal the chemical complexity in the universe.

Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.

Researchers have discovered a new way to target and kill cancer cells in hard-to-treat brain tumours using electrically charged molecules to trigger self-destruction, that could be developed into a spray treatment used during surgery.

The era of artificial-intelligence chatbots that seem to understand and use language the way we humans do has begun. Under the hood, these chatbots use large language models, a particular kind of neural network. But a new study shows that large languag…

Although a simple molecule, nitric oxide is an important signal substance that helps to reduce blood pressure by relaxing the blood vessels. But how it goes about doing this has long been unclear. Researchers now present an entirely novel principle tha…
