The types of ocean bacteria known to absorb carbon dioxide from the air require more energy -- in the form of carbon -- and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.

Scientists have used ultrashort laser pulses to make the atoms of molecules vibrate and have gained a precise understanding of the dynamics of energy transfer that take place in the process.

A research team has developed a skin-attachable auditory sensor, which recognizes human voices in noisy environments and when users wear facemasks. The new sensor will be useful in microphones that facilitate communication in disaster situations and for healthcare devices that diagnose respiratory diseases.

The eyespots of many prey animals deter predators from attacking, like those of the peacock butterfly. In a new study, researchers show that the configuration of eyespots have an impact on the prey's survival. The deterrent potential of eyespots is larger when they appear to look directly at a predatory chick. The most effective deterrent are concentric circles that subjectively appear to maintain eye contact regardless of the perspective from which they are approached.

If a therapy for chronic back pain is tailored specifically to a patient's individual requirements, the chances of success are far greater than with standard forms of treatment. Accompanied by a psychotherapeutic procedure in the shape of cognitive behavioral therapy, the pain can be alleviated even more effectively.

When states want to gauge quail populations, the process can be grueling, time-consuming and expensive. It means spending hours in the field listening for calls. Or leaving a recording device in the field to catch what sounds are made -- only to spend hours later listening to that audio. Then, repeating this process until there's enough information to start making population estimates. But a new model aims to streamline this process. By using artificial intelligence to analyze terabytes of recordings for quail calls... Читать дальше...

A team led by researchers has developed a powerful computational tool for understanding brain health and disease, providing an enhanced way of characterizing the activity of the brain during sleep.

Researchers have successfully 3D bioprinted breast cancer tumors and treated them in a breakthrough study to better understand the disease that is one of the leading causes of mortality worldwide.

A substantial proportion of ethnically diverse children from low-resource backgrounds with severe COVID-19 illness are reporting long-term complications from the virus, according to research.

A new animal study investigates why individuals with obesity may have a particularly difficult time fending off SARS-CoV-2, the virus that causes COVID-19. Specifically, female obese mice experienced worse disease symptoms, showing the importance of both obesity and biological sex in COVID-19 outcomes.

A new study has produced a proof of principle for a new 'universal' means of treating COVID-19. Researchers demonstrated in a mouse model that it's possible to prompt the production of a protein that can block multiple variants of the SARS-CoV-2 virus from entering cells and causing respiratory disease.

Researchers have developed a new, machine learning-based technique to accurately classify the state of macrophages, which are key immune cells. Classifying macrophages is important because they can modify their behavior and act as pro- or anti-inflammatory agents in the immune response. As a result, the work has a suite of implications for research and has the potential to one day make major societal impact. For example, this new approach could be of use to drug designers looking to create therapies... Читать дальше...

A study found that 57 percent of the participants were habitual snoozers.
