Current pace of action on climate change is “unthinkable” state ex UN climate leaders

Credit: CC0 Public Domain Justifiable pride can be taken in the incremental accomplishments of international climate change cooperation, but it is “unthinkable” to continue at the current pace. The global response to climate change is completely insufficient and leaves the world on a “road to hell”. That’s according to four former senior members of the […]

Antiferromagnets are suitable for dissipationless nanoelectronics, contrary to current theories

Electrons (gray wave packets) in antiferromagnetic (left) and nonmagnetic (middle) crystals move along the applied electric current (right). The combination of antiferromagnetic and nonmagnetic atoms (right) generates surprisingly transverse Hall motion of the electron. In the left and right panels, the blue and red shadings mark the positive and negative magnetization densities. Credit: Libor Šmejkal […]

The current state of the pandemic in 5 graphs

We could be in for a tough winter. (Infographic by Sara Chodosh/) Approximately one eternity ago in April 2020, experts thought we’d see 100,000 to 200,000 COVID deaths. It’s now October, cases are rising yet again, and the Centers for Disease Control recently estimated that we’re at around 285,000 deaths from both direct and indirect […]

Current Chernobyl-level radiation harmful to bees: study

Colony reproduction reduced by 30 to 45 percent at radiation doses previously considered too low to impact insects Bumblebees exposed to levels of radiation found within the Chernobyl exclusion zone suffered a “significant” drop in reproduction, in new research published Wednesday that scientists say should prompt a rethink of international calculations of nuclear environmental risk. […]

Could excessive sugar intake contribute to aggressive behaviors, ADHD, bipolar disorder? New peer-review paper looks at evolution and current Western diet to help explain manic behaviors — ScienceDaily

New research suggests that conditions such as attention deficit hyperactivity syndrome (ADHD), bipolar disorder, and even aggressive behaviors may be linked with sugar intake, and that it may have an evolutionary basis. The research, out today from the University of Colorado Anschutz Medical Campus and published in Evolution and Human Behavior, presents a hypothesis supporting […]
