Galaxy clusters grow over time under gravity and, in the present-day universe, can contain hundreds or even thousands of galaxies, as well as hot gas and dark matter. As time goes by, their galaxies burn through the fuel available and evolve from vigorously star-forming galaxies into red and dead galaxies.

In the last few decades more has been learned about the impact of oral health on the entire human biological system. And more is being done to reduce factors that lead to an estimated 15 million babiesborn prematurely or preterm (defined as delivery before the 37th week of pregnancy) each year. Preterm babies are at greater risk of experiencing serious health problems.Due to correlation between preterm births and poor oral care, researchers have looked at various ways to improve dental health during pregnancy, including “deep-teeth cleaning” like scaling and planing to remove plaque and tarter on the teeth and below the gum line, but that hasn't seemed to be very effective.

Our auditory system is able to detect sounds at an implicit level. The brain can distinguish between even very similar sounds, but we do not always recognize these differences. A new study demonstrated using sound perception during passive listening; when the subject is not trying to explicitly hear the differences.The result was that the human brain unconsciously distinguishes between even very similar sound signals during passive listening.  

The ongoing SARS-CoV-2 pandemic and new mutations in viral genetic sequences have made "variant" part of the cultural lexicon, because they can have significant impacts on the virus’s transmissibility and the damage it causes. Researchers have long been concerned that could happen in the HIV-1 virus, which has been mitigated thanks to safer sex practices and modern science but still affects 38 million people worldwide.

This is the third coronavirus pandemic of this century, after SARS and MERS, and due to that many forget that influenza is a chronic killer, 40-60,000 deaths in America alone each year. To mitigate those effects, there is a seasonal flu vaccine. Each year researchers model how they expect the virus to mutate and then they create a vaccine based on that. Some years are more successful than others but if people do get the flu, effects will be reduced.

Our life on earth began in water but how did it 'evolve'? To get an understanding of the link between the chemistry of carbon and water, scientists can track the various forms, or isotopes, of its constituent hydrogen and oxygen atoms over the history of the universe, like a giant treasure hunt. Recently, researchers from the CNRS, Paris-Saclay University, the French Alternative Energies and Atomic Energy Commission (CEA), and the University of Pau and the Pays de l’Adour (UPPA), with support from the Muséum National d’Histoire Naturelle (MNHN), have followed the trail of the isotopic composition of water back to the start of the solar system, in the inner regions where Earth and the other terrestrial planets were formed.

A group of vegetarian activists argue that the COVID-19 Omicron variant is good reason for people to adopt a plant-based diet.

Women in sexual relationships with men whom they perceive as having more fragile masculine ideas change their own behavior to protect the feelings of the men. They reported more faked orgasms and lower sexual satisfaction the more they reported  their partner’s sense of masculinity as fragile.Unlike more surveys, these new studies examine the subject from the perspective of women who seek to protect their partners’ sense of masculinity, perhaps at their own expense.

A new analysis of data shows the medical community may need to rethink the optimal strategy for treating blood clots and bleeding in hospitalized COVID-19 patients. Patients with COVID-19 in the intensive care unit (ICU) prescribed full-dose blood thinners were significantly more likely to experience heavy bleeding than patients prescribed a smaller yet equally effective dose - nearly 1 in 7 COVID-19 patients in the ICU experienced severe bleeding when given full-dose blood thinners. Almost all patients who experienced significant bleeding were mechanically ventilated and receiving full-dose anticoagulants (blood thinners).

In the United States, flying cars have been almost here since the 1980s but, like Tubesat for personal satellites, it's basically involved a lot of money raised and no actual delivery. In Slovakia, a 1.6L BMW engine in a two-seat prototype has changed all that. After a successful demonstration last year, AirCar has performed 70 hours of flight testing compatible with European Aviation Safety Agency (EASA) standards, including over 200 takeoffs and landings. They even did it on autopilot. It can go from ground driving to air travel in under 3 minutes. 

Unless you see yourself as a human with a Dogecoin dog atop your neck, avatars are not very realistic. The lack of realism in the digital realms, combined with how tedious VR glasses are, means conferences, meetings and discussions with work colleagues are only slightly more advanced than conference calls of 40 years ago.

It could be a neutron star or it could be a white dwarf with an ultra-powerful magnetic field but something is releasing fantastic bursts of energy at periodic intervals.When the burst happens, it is one of the brightest radio sources in the sky.Objects that turn on and off aren’t new to astronomers, they're called ‘transients’, and they are the death of a massive star or the activity of the remnants it leaves behind. ‘Slow transients’, like supernovae, might appear over the course of a few days and disappear after a few months. ‘Fast transients’, like a type of neutron star called a pulsar, flash on and off within milliseconds or seconds.
