Scientists grew human tear ducts in a lab and taught them to cry

 In this article, scientists are creating human tear ducts that have the ability to cry and are implanting them into mice. In the Netherlands, disembodied human tear glands are being grown in petri dishes. This could be a step forward in the treatment of dry eye. The scientists divided this study into 3 experiments. The first experiment was to grow the glands, the second was to implant them into mice, and the third was to focus on pinpointing the origin of dry eye. Their experiment showed that the mouse organoids modified to lack PAx6 produced fewer tears, showing the idea that that gene is linked to dry eye.

I think implanting disembodied human tear glands into mice is kind of gross. However, if it's a step to possibly get better treatment for those with dry eye, I think it's a good idea. I think its great that they found the specific gene linked to dry eye.

    This is such a weird experiment for scientists to think of. I agree that it is a gross process to insert tear glands from humans into mice, but I want to know whether or not this theory will continue and work. This is not something I would ever think of doing to begin with let alone attach it to a mouse. Overall I think this a good idea and hope it works to help dry eye.

    Reading this made my eyes water. Anyways it's kind of cool that they are trying to come up with a solution to fry eye. I thought they already had treatments for that but I don't have dry eyes so I wouldn't know.

Current event

I am just doing a trial current event-  Are you supposed to put the link to your article in the summary?  Do you know how to do that?  My current event is an article from the magazine The Week.  It is titled   It's not just the germs — it's also the genes  The article discusses how a person's genes play a part in how viruses react within that body.  It talks about how some people may get a virus more seriously than another & how scientists can look at that information and develop therapies from.  Just so you know The Week pulls articles from other sources-  I did backtrack to check the source they got the original article from & it checks out.

Law enforcement intercepted a ricen laced package and letter sent to Donald Trump that supposedly came from St. Hubert Quebec. A women has been arrested in the case but they are still investigating.  Ricin is a highly toxic compound extracted from castor beans that has been used in terror plots. It can be used in powder, pellet, mist or acid form. If ingested, it causes nausea, vomiting and internal bleeding of the stomach and intestines, followed by failure of the liver, spleen and kidneys, and death by collapse of the circulatory system .

Coral Genetic Diversity Relates to Distinct Lifestyles

 According to microbiologist, Rebecca Vega-Thurber, coral supports more species per square meter than any other habitat. Coral is a complex organism that is able to hide its diversity in plain sight and while scientists always thought there was one distinct species, they have now been able to conclude that there are actually four. The coral's internal structures look almost identical which is what makes it so hard to decipher the difference between the four different kinds, which concludes that millions of years ago, the coral diverged together. Scientists also found that these different species of coral is found at different water depths of the ocean. They also have different amounts of photosynthetic algae and pigments. When this study was conducted, it allowed us to know cryptic reef corals are splitting up their shared ecological space. I think that this is important to know because now we are able to conduct more studies to find out why coral has different properties at differ...
