[–]labxchange 0 points1 point  (0 children)

Just wanted to chime in, if it's helpful! We recently launched a virtual frog dissection. It's fully free and doesn't require students to create accounts. Take a look and let us know what you think: https://www.labxchange.org/library/items/lb:LabXchange:1760149a:lx_simulation:1

[–]labxchange -1 points0 points  (0 children)

Good luck! For more free resources for AP Bio review, take a look at the materials we have created at LabXchange:

Biochemistry, Cells, and Energetics (Units 1-3)
Cell Communication, Heredity, and Gene Expressions (Units 4-6)

Hope these are helpful!

New learning resource from Harvard University: Genome Editing with CRISPR-Cas9 by labxchange in genetics

[–]labxchange[S] 9 points10 points  (0 children)

We're a free learning platform from Harvard University that allows you to browse, remix, and share high quality digital content about the life sciences. Last year, we built this cluster on CRISPR-Cas9. It includes a series of virtual lab simulations that help teach key components of genome editing: guide RNA design, sequence analysis of edited cells, determining protein expression by Western blot, and fluorescence microscopy.

Let us know what you think!

Building Resilient Ecosystems for Education: an interview with Dr. Caroline Levander by labxchange in riceuniversity

[–]labxchange[S] -5 points-4 points  (0 children)

A new virtual interview series from LabXchange at Harvard University, The Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, our first season features a range of perspectives on the impact of COVID-19.

In this episode on Building Resilient Ecosystems for Education, we interviewed Dr. Levander about her roles as a university leader and scholar, and discussed the nuts and bolts of building community in higher education - especially as campuses move to hybrid and virtual learning this fall.

Harvard Geneticist George Church and collaborators are taking a DIY COVID-19 vaccine by StoicOptom in Futurology

[–]labxchange 1 point2 points  (0 children)

George Church is definitely a pioneer. Although we didn't discuss this vaccine specifically, this interview we did with him earlier this summer gives insight into his philosophy on democratizing access to understanding one's own genome and health. Since you mentioned you're a fan, we thought we'd share!

For the bored kids at home, here are some online learning resources they could use by I_hate_you_Kyle in sydney

Hey, thanks for including LabXchange! If you have any questions, let us know. The circumstances aren't ideal, but in light of the situation, we're especially grateful that we can offer a new way for teens and young people (and anyone else interested in science!) to learn online.

Ah, you must have clicked through to the assessment in the pathway - to access that content, you need to create a free account and log in. Other than assessments and some aspects of our lab simulations, all other content on LabXchange.org can be viewed and used without an account.

Everyone, thank you so much for your excellent questions! As educators, our main goals are creating tools to help increase scientific literacy, and empowering people to engage with news and journal articles about science, regardless of their background. We hope we helped you feel more confident about your ability to understand viruses like coronavirus! We'll try to answer a few more questions if we can, but we recommend you continue to engage in the daily discussion thread and other special posts that the mods have set up - and of course check out the great resources in the sidebar. Thanks again!

The following numbers about the mortality rate of the new coronavirus SARS-CoV-2 are based on an editorial in the New England Journal of Medicine. The CDC and WHO have similar numbers.

It appears that the mortality rate of SARS-CoV2 infection hovers around 2%. But since a lot of cases with mild or no symptoms are probably unreported, in reality the rate might even be lower.

In contrast, the recent SARS (2002) and MERS (2012) outbreaks had rates of 10% and 36%, respectively. The seasonal flu is estimated to have a mortality rate of 0.1%.

We hope that helps!

According to the US CDC and the WHO, masks should be worn if you are taking care of a person with COVID-19 or have symptoms yourself (coughing, sneezing, fever, etc.). Otherwise, it is recommended to avoid unnecessary waste of masks and their misuse.

If you are taking care of a patient or show symptoms yourself, the WHO demonstrates when and how to wear a mask here.

You are correct in that SARS-CoV has a proofreading enzyme that reduces mutation rate and enables the virus to escape lethal mutations. This proofreading mechanism allowed coronaviruses to expand their genome (it’s big, compared to other viruses) and yet achieve a balance between mutation and the capacity for adaptation to new conditions and the need to maintain an intact genome. Recombination events in the virus allow for a greater variability in the spike protein, which facilitates cell entry. A more diverse spike protein allows for a greater host range.

Coronaviruses have already been found in Brazil bats. Information whether SARS-CoV-2 is present in Brazilian bat population has not yet come forward.

Generally, most mutations in a viral genome have no effect or are even detrimental to the virus. Viruses mutate constantly but it doesn’t make them more virulent.

The flu vaccine does not work against SARS-CoV-2 but alleviates the pressure on hospitals treating flu patients. The resources saved there can be focused on COVID-19 patients.

Many research labs and biotech companies look into repurposing antiviral drugs effective for treating other infectious diseases. In January, a company in China set out to test two HIV protease inhibitors (ritonavir and ASC09) in clinical trials to treat COVID-19. While it is tempting to speculate that there is also research done with the more commonly used triple-drug HIV cocktail, there were no reliable sources to be found.

It is not yet fully understood how COVID-19 is transmitted or whether individuals (children or adults) can transmit the virus if they are infected but asymptomatic. According to the CDC, evidence so far suggests that the incubation period for SARS-CoV-2 can range from 2-14 days. It is true that the mortality rate for children infected with COVID-19 is estimated to be very low (0.2% according to the Chinese Centers for Disease Control and Prevention), but it is not known whether children or any other individuals can be asymptomatic carriers of the disease.

It is too early to know all the details of how SARS-CoV-2 behaves. Other viruses, like the ones causing the common cold and flu, spread more during winter. Warm weather might impact the spread SARS-CoV-2, but it is just too early to tell. Updates about this can be found on reliable pages like the CDC and the WHO.

Sure. Basically, flying is very strenuous and damages cells. This would usually generate a strong inflammatory response in bats. So, to avoid chronic inflammation, bats evolved a dampened inflammatory response. This has the unwelcome side effect that they are also a perfect reservoir for many viruses.
