A new paper
posits that fluctuating estrogen levels may make alcohol more rewarding.
The giant caveat is that the study was in mice, and despite what you may read in corporate media, mice are not little people, so this research is firmly in the "exploratory" part of science.
We know dogs will try to rescue humans, those Lassie stories were based on events that have happened for as long as humans and dogs have co-existed, but simply observing dogs rescuing someone doesn't tell you much about dogs' actual interest in rescuing humans
So psychologists at Arizona State University set up an experiment assessing 60 pet dogs' propensity to rescue their owners
. None of the dogs had any kind of rescue training.
In high school biology you learned that in humans, a normal cell contains 23 pairs of chromosomes; 22 autosomes, which are the same in both males and females, while in the 23rd, the sex chromosomes, females have two copies of the X chromosome while males have one X and one Y.
Their differences don't stop there. Chromosome pairs are numbered according to size, pair 1 being largest and 23 the smallest. And the Y is tiny compared to the X. X contains thousands of genes critical for life while the Y provides the instructions for initiating male development and making sperm.
Exactly how they work together during meiosis, the form of cell division that creates sperm and egg, contains a science mystery.
A 425-million-year-old Kampecaris obanensis
millipede fossil is the world's oldest "bug
." It is older than any known fossil of an insect, arachnid or other related creepy-crawly and it was found on the Scottish island of Kerrera.
It's about 75 million years younger than the age other scientists have estimated the oldest millipede to be using a technique known as molecular clock dating, which is based on DNA's mutation rate. Other research using fossil dating found that the oldest fossil of a land-dwelling, stemmed plant (also from Scotland) is 425 million years old and 75 million years younger than molecular clock estimates.
Two cities, Los Angeles and Indianapolis, reported higher than usual domestic violence incidents once
COVID-19 stay-at-home restrictions were implemented in March.
For their paper, the scholars analyzed police calls for service before and during the coronavirus pandemic; from Jan. 2 to April 18 in Los Angeles and from Jan. 2 to April 21 in Indianapolis.School, restaurant and bar closures were ordered in both cities on March 16th. Los Angeles implemented government lockdown orders on March 20th and Indianapolis enacted similar orders on March 24th.
A new study has found that even when it comes to something as broad as "wellness" such wellness programs have little recognizable impact on employee health, health beliefs, or medical utilization.
All things they were supposed to improve.
