A small-scale study observing 16 cats has revealed that cats actually know when they hear their owner’s voice that the owner’s tone is directed to them. They change their behaviors to show that they understand, according to a press release.

This is the first study to record such electrical activity from inside the brain.

How do people remember the things they’ve learned? To get to the bottom of the mystery, scientists undertook a study that looked deep inside the brain.

Neuroscientists from Northwestern University and clinicians from the University of Chicago Epilepsy Center examined the electrical activity in the brains of five patients at the center in response to sounds administered by the research team as part of a learning exercise.

Brian Stanley is a living human cyborg. He has gone viral after sharing a video on social media with an eye flashlight that can light up the whole room. After losing one eye to cancer.

As Brian Stanley suggested in the video, the eye has a battery life of roughly 20 hours, and “it does not get hot.”

They’re tiny but have a knack for saving human life.

The Belgian non-profit organization APOPO trains rats to help earthquake survivors. Called RescueRATs, these rats are preparing to save those under the earthquake debris with their high-tech backpacks on their backs.

The world’s most powerful operational rocket could finally launch again as soon as next week.

SpaceX’s Falcon Heavy, the most powerful rocket in the world, is approaching its first launch in over three years. The massive launch system, which is powered by three modified Falcon 9 first-stage boosters, is now linked together and awaiting launch from Pad 39A at NASA’s Kennedy Space Center.

Ahead of the launch, SpaceX has shared an image of the behemoth’s 27 Merlin engines on Twitter. “Falcon Heavy in the hangar at Launch Complex 39A,” the company wrote alongside the impressive photo.

By manipulating van der Waals forces, it may be possible to create novel types of friction-free nanomachines, propulsive systems, and energy storage devices.

Recent evidence points out the role of the gut microbiota in the aging process. However, the specific changes and relevant interventions remain unclear. In this study, Senescence Accelerated Mouse-Prone 8 (SAMP8) mice were divided into four groups; young-FMT-group transplanted fecal microbiota from young donors (2–3°months old) and old-FMT-group transplanted from old donors (10–11°months old); additionally, other two groups either adult mice injected with saline solution or untreated mice served as the saline and blank control groups, respectively. All mice were intervened from their 7-months-old until 13-months-old. The open field test at 9 and 11°months of age showed that the mice transplanted with gut microbiota from young donors had significantly better locomotor and exploration ability than those of transplanted with old-donors gut microbiota and those of saline control while was comparable with the blank control. 16S rRNA gene sequencing showed that the gut microbiome of recipient mice of young donors was altered at 11°months of age, whereas the alternation of the gut microbiome of old-donor recipient mice was at 9°months. For comparison, the recipient mice in the blank and saline control groups exhibited changes in the gut microbiome at 10°months of age. The hallmark of aging-related gut microbiome change was an increase in the relative abundance of Akkermansia, which was significantly higher in the recipients transplanted with feces from older donors than younger donors at 9°months of age. This study shows that fecal microbiota transplantation from younger donors can delay aging-related declines in locomotor and exploration ability in mice by changing the gut microbiome.

Aging is inherently accompanied by the decline of physical and mental abilities, including locomotor, cognition, and bodily functions, to subsequently cause frailty syndrome, neurodegenerative diseases, and other age-related diseases, which reduce the quality of life of the aging population (Hou et al., 2019). Aging mechanisms and anti-aging interventions have long been a major focus of biomedical research, which is particularly relevant given the rapidly aging society.

The gut is a major organ for nutrients absorption, metabolism, and immunity, and contains hundreds of millions of microorganisms and their metabolites, which comprise the gut microbiota (Heintz and Mair, 2014) that interacts with host cells and tissues (Huang et al., 2021). Our previous study reported continuous changes in the gut microbiome of centenarians during their transition from a healthy status to death. The most significant changes of gut microbial communities in the period were found to occur at 7°months prior to death, suggesting that this may be a turning point of significant changes in the gut microbiome of centenarians (Luan et al., 2020). Recent studies have revealed an important relationship between the gut microbiome and aging-related diseases such as Alzheimer disease (Ticinesi et al., 2018; Haran and McCormick, 2021), suggesting that the gut microbiome plays an essential role in the aging process.
