A team of engineers, biologists, and geneticists has developed a new way of studying the heart: they’ve built a miniature replica of a heart chamber from a combination of nanoengineered parts and human heart tissue.

The seismometer placed on Mars by NASA’s InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 Mars-quake. The pair are the first recorded events to occur on the planet’s far side from the lander and ar…

Federal funding for biomedical research has a ‘ripple effect’ of stimulating new studies even beyond the original purposes of a grant and may provide unexpected benefits, a new study suggests.

Researchers studying the effect of the monoclonal antibody Leronlimab on long COVID-19 may have found a surprising clue to the baffling syndrome, one that contradicts their initial hypothesis. An abnormally suppressed immune system may be to blame, not…

Scientists have made a major breakthrough in detecting changes in fossil fuel carbon dioxide emissions more quickly and frequently.

For years, the brain has been thought of as a biological computer that processes information through traditional circuits, whereby data zips straight from one cell to another. While that model is still accurate, a new study shows that there’s also a se…

Researchers describe a technique of volumetric 3D printing that goes beyond the bottom-up, layered approach. The process eliminates the need for support structures because the resin it creates is self-supporting.

Scientists have detailed a roadmap for untangling a key aspect of magnetic recognition that could deepen insight into the workings of the cosmos.

Using a scanning tunneling microscope equipped with a femtosecond terahertz laser, scientists have exploited the quantum properties of a two-atom hydrogen molecule to observe changes in the electrostatic field of a target sample, turning the hydrogen m…

Over the past 15 years, public health authorities have downgraded recommendations for the prostate-specific antigen (PSA) test as a screening tool to reduce the overdiagnosis and overtreatment of men with low-grade prostate cancer. Now, researchers hav…

A new study uses an innovative approach to examine a shallow-water hydrothermal system and the production of microbes there in situ and near natural conditions as a model to assess the importance of hydrothermal fluid circulation on chemosynthesis.

Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers have now developed a process for the photocatalytic degradation of these pollutants when they flow through p…

Genetics and other factors that can determine if a woman is at risk for a recurrence of breast cancer have been identified, providing new research avenues for preventing a new tumor from developing.

In a small but multi-institutional study, an artificial intelligence-based system improved providers’ assessments of whether patients with bladder cancer had complete response to chemotherapy before a radical cystectomy (bladder removal surgery).

New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean — one of Earth’s main cooling systems.

Optical solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers have solved the puzzle of how these temporal links are formed.
