Threat from nuclear weapons and missiles has grown since Trump entered office

The situation presents a broader challenge to the United States. The administration has heralded an era of “great power competition” with China and Russia, resulting in a competitive buildup that arms-control advocates warn is risking a full-blown arms race.

Russia is developing nuclear-armed underwater drones, nuclear-powered cruise missiles and other destabilizing weapons designed to penetrate U.S. missile defenses. China is ramping up its missile force and building out its nuclear capabilities with new nuclear submarines. And the United States is modernizing its own arsenal, while adding low-yield nuclear warheads to submarines and enhancing missile defenses. All the while, Iran and North Korea are advancing as threats.

The result is an escalatory cycle that experts say is threatening decades of progress controlling the world’s most dangerous weapons. A recent report from the Center for Strategic and International Studies warned that the decline of U.S. global influence and the rise of regional

Human intestinal organoids grown from stem cells used to model congenital disorder in babies — ScienceDaily

Scientists at Cincinnati Children’s used human intestinal organoids grown from stem cells to discover how our bodies control the absorption of nutrients from the food we eat. They further found that one hormone might be able to reverse a congenital disorder in babies who cannot adequately absorb nutrients and need intravenous feeding to survive.

Heather A. McCauley, PhD, a research associate at Cincinnati Children’s Hospital Medical Center, found that the hormone peptide YY, also called PYY, can reverse congenital malabsorption in mice. With a single PYY injection per day, 80% of the mice survived. Normally, only 20% to 30% survive.

This indicates PYY might be a possible therapeutic for people with severe malabsorption.

Poor absorption of macronutrients is a global health concern, underlying ailments such as malnutrition, intestinal infections and short-gut syndrome. So, identification of factors regulating nutrient absorption has significant therapeutic potential, the researchers noted.
