President Trump says he doesn't 'particularly believe' in UFOs existence

Endosymbiosis is a remarkable biological phenomenon in which one creature resides within another. Such an unconventional partnership is usually advantageous to both parties. Even in human bodies, we find evidence of such cohabitation: mitochondria, the cells' powerhouses, originated from an ancient endosymbiosis. Bacteria long ago invaded and colonized other cells. This coexistence created the groundwork for mitochondria, which are found in the cells of plants, animals, and fungi.

Researchers at Virginia Tech have discovered how bacteria change molecules in order to infect their host.

Previous studies found that fewer than 40 per cent of patients with stable chest pain who underwent invasive coronary angiography had obstructive coronary artery disease. Recent randomized clinical trials have shown that evaluating these patients first with computed tomography angiography (CTA) is beneficial, and a new study presented at the American College of Cardiology Cardiovascular Summit supports this strategy, finding that CT was associated with a higher likelihood of revascularization when compared to other imaging modalities or no testing.

A study published in Microbiology Spectrum, an American Society for Microbiology magazine, found that tomato juice helps eliminate Salmonella Typhi and other bacteria that might harm digestive and urinary tract health

A new analysis of U.S. Forest Service data shows that climate change is changing forests differently across the country. With increasing temperatures, intensifying droughts, wildfires, and disease outbreaks wreaking havoc on trees, researchers warn that forests in the American West are facing the brunt of the repercussions.

A study published in the issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS), suggests that performing targeted muscle reinnervation (TMR) at the time of amputation can reduce pain scores and prevent complications related to abnormal nerve regrowth.

A study found that pathogens can use physical force to defeat a cell's defence mechanisms. The study found that pathogens can avoid being ingested by immune cells by exerting a "propulsive force."

A study found that smaller hippocampal volume was associated with poorer performance on fluid cognitive functioning.

With the development of new medications that can target the amyloid-beta plaques in the brain that are an early symptom of Alzheimer's disease, new methods for determining whether memory loss and thinking issues are caused by Alzheimer's disease or another neurodegenerative disease are required.

A study led by Nagoya University Graduate School of Medicine in Japan evaluated screen time in children with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). The amount of time spent on a screen device, such as a smartphone, computer, television, or video gaming system, is referred to as screen time. The researchers discovered that youngsters with a genetic propensity to ASD used screens for longer durations of time. Meanwhile, even if their initial screen time was limited, children with ADHD gradually increased their screen time as they grew older.
