For decades, schizophrenia and bipolar disorder (BD) were treated as distinct and unrelated psychiatric disorders. Schizophrenia is a psychiatric disorder characterized by altered thinking and emotional patterns, hallucinations, false or irrational beliefs (i.e., delusions), cognitive deficits, and disorganized speech. BD, on the other hand, is marked by extreme mood swings, ranging between periods of high-energy (i.e., mania or hypomania) and depressive episodes.

While the symptoms of schizophrenia and BD are markedly different, many patients diagnosed with...

Microbes harvest metals from meteorites aboard space station

If humankind is to explore deep space, one small passenger should not be left behind: microbes. In fact, it would be impossible to leave them behind, since they live on and in our bodies, surfaces and food. Learning how they react to space conditions is critical, but they could also be invaluable fellows in our endeavor to explore space.

Microorganisms such as bacteria and fungi can harvest crucial minerals from rocks and could provide a sustainable alternative to transporting much-needed resources from Earth.

Researchers from Cornell and the University of Edinburgh collaborated to study how those microbes extract platinum group elements from a meteorite in microgravity, with an experimen...

Gut bacteria can sense their environment and it’s key to your health

Gut Bacteria Can Sense Their Environment

Your gut bacteria are chemical detectives—sniffing out nutrients and even feeding each other to keep your microbiome thriving. Your gut is home to trillions of bacteria that constantly “sense” their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can detect a surprisingly wide range of chemical signals produced during digestion, including byproducts of fats, proteins, sugars, and even DNA. These microbes use specialized sensors to move toward valuable nutrients, with lactate and formate standing out as especially important fuel sources...

Study suggests protein made in the liver is a key factor in men’s bone health

New research suggests the liver plays a previously unrecognized role in bone health, but only in males. A McGill University-led study published in Matrix Biology found that a protein made in the liver helps regulate bone growth in male mice, but not in females. The findings may help explain why men with liver disease are more likely to experience bone loss.

The protein, known as plasma fibronectin, is naturally present in blood at higher levels in men than in women, declines when the liver is damaged and builds up in bone to modulate bone formation...
