Hi! We’re here to talk about all things CRISPR and NIH’s Center of Excellence in Genomic Science. We’re researchers from Jennifer Doudna’s lab at UC-Berkeley and program directors from the National Human Genome Research Institute, part of NIH. Ask us anything!

A surprising study found people who had smoked pot as teens performed better on a memory test, based on an fMRI study published in journal NeuroImage.

There were no safety concerns in smokers who used e-cigarettes in a 2-year clinical trial. Vaping was associated with a reduction in cigarette consumption and a reduced exposure to cigarette smoke constituents, with no increase in body weight.

Chronic traumatic encephalopathy (CTE) results from head injuries, not concussions. New research explains why 20% of athletes who exhibited the early stages of the progressive brain illness postmortem never had a diagnosed concussion.

Brains of Jazz and Classical Pianists Work Differently - Scientists observed that while playing the piano, different processes occur in jazz and classical pianists’ brains, even when performing the same piece. Classical pianists focus their playing on the “How”, and jazz pianists on the “What”.

It is easier to spread the flu virus than previously thought. People commonly believe that they can catch the flu by exposure to droplets from an infected person's coughs or sneezes. But new information about flu transmission reveals that we may pass the flu to others just by breathing.

Researchers explore psychological effects of climate change. They found that while some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression
25
An infant's history and memory response to touch, both felt and seen, sets the stage for empathy. The evidence of activity in the somatosensory cortex for both “felt touch” and “observed touch” shows that 7-month-old infants have already made a basic connection between “self” and “other.”
33
The hunter-gatherer lifestyle could help explain superior ability to identify smells and possibly smell detection. Some foraging communities can identify smells as easily as colors without using analogies.

Scientists develop miniature, low-power instruments and new techniques that could definitively detect life on Mars.

According to a new study, published in the journal Addiction, frequent cannabis use by adolescents dropped in states where medical marijuana is legal under state-regulated close physician supervision.

Evening Hours May Pose Higher Risk for Overeating, Especially When Under Stress, Study Finds. The experiments add to evidence that “hunger hormone” levels rise and hormones that make us feel full decline during evening hours.

The death rate in USA isn't decreasing as expected, and some experts blame the opioid epidemic. But a new study suggests America's increasing obesity is what's behind the slowdown. Excess weight led to nearly 200,000 excess deaths in 2011. It reduced life expectancy by almost one year at age 40.

Birds of prey in Australia have been found intentionally starting fires to get prey out in the open

Spontaneous perforation of the pharynx is an unusual condition. This case reports a rare spontaneous perforation of the pyriform sinus after a forceful sneeze, leading to cervical subcutaneous emphysema and pneumomediastinum (TL;DR - 'Don't hold your nose and close your mouth when you sneeze')

Homing in on a key factor of climate change: The sensitivity of Earth’s climate to atmospheric carbon dioxide levels is a big unknown in predicting future global warming. A compelling analysis suggests that we can rule out high estimates of this sensitivity.

500 years later, scientists discover what probably killed the Aztecs. Within five years, 15 million people – 80% of the population – were wiped out in an epidemic named ‘cocoliztli’, meaning pestilence

The heatwaves seen in the northern Pacific and Australia in 2016 were both the most intense and longest lasting on record. Researchers concluded that these heatwaves were made 50 times more likely by climate change.

The Varroa mite may be the biggest threat to honeybees. Now, scientists have found a new way to fight them. Tiny amounts of lithium chloride kill 90% to 100% of mites without killing bees.

In three weeks in 2015, 62 percent of the global population of saiga antelopes died during a hot weather-caused epidemic in Kazakhstan, a repeat of a 1988 die-off, also from a warming climates.

2 wait_wait_wha Wait, wait... This would be awesome.... ***Except*** for the life cycle of varroa. Mite enters cell with bee larva. Cell gets sealed. Mite moves underneath larva, into bee food. Mite feeds on prepupa. Female lays eggs. Eggs develop from mite larva and feed on bee. They mate inside the cell. Females leave cell when bee breaks out of cell. Males stay in cell. Females ride on bee to other location.   So... short story, this chemical only works on mites *outside* of cell. The chemical will remain in the colony for quite some time, and the honey, pollen, wax cannot be harvested.   ***Solution?***   Get hygienic queens, use with powdered sugar (hygienic bees want to clean each other more, powder sugar all over hive, triggers cleaning), fumigate with formic acid (kills mites, bees okay, stuff made by ants), use drone frame rotation (varroa seem to like larger cells, drone cells are larger, females move in to lay eggs, cells get sealed, take frame out and destroy it -it only contains drones and mites), periodically "cook" worker bees (varroa dies over 116F, bees are okay).   And, for those whose "colony collapse"... how about you stop splitting in the fall? What did you expect? Of course you are going to lose more than 50%?!? Try **combining** instead. Splitting became a fashion in the early 50's in the West because it doubles the production for next year. Except it halves the strength of a hive that just spent working all summer....
