When wood turns into glitter
Many moons ago, in the area that is now Nevada ancient woodlands were living through events that would result in some stunning pieces that grace museums around the world. Some 14 million years ago in the Miocene, the area was thickly forested rather than displaying the arid environment of today. It was also much closer to sea level, since the area has been extensively uplifted since then, due to tectonic stresses caused by the subduction of the Pacific and Farallon plates under the North American one. The area also saw intense subduction related volcanism (ongoing along the USA’s west coast to this day), which periodically covered the forests in silica rich ash. As groundwater interacted with the magma below, weathering the layers of ash into clays, it dissolved silica, precipitating it when conditions such as temperature and pressure changed, replacing the ash covered trees with opal, sometimes so clearly that every cell is visible. While not really suitable for jewellery use due to its tendency to crack as it dries out (called crazing in the trade), these rare logs from the Virgin Valley of Nevada make for stunning collector’s specimens

Dinoflagellates The dinoflagellates are a large group of flagellate protists. Most are marine plankton, but they are common in fresh water habitats as well. They are characterized by two flagella, one girdling the cell and the other trailing the cell. Some dinoflagellates exist in coral, in a symbiotic relationship. These dinoflagellates are termed the zooxanthellae. Other dinoflagellates occur in such high numbers that the water is colored red, a phenomenon known as a red tide.
Most Common Profile
Fellow Students
My Background
Adjustments
The most common profile in study abroad is students from "elite colleges, white, female, major in arts/humanities, and have highly educated parents." Let's see how that compares to me. I am from a small liberal arts school (does that count as elite?), I am white (check), male (nope), I have majors in biology (nope) and Spanish (check), and both of my parents completed high school but never went to college so they would not be considered highly educated.
Now, compared to my fellow study abroad students, that profile fits a bit more. Girls out number guys by slightly more than 2 to 1, most of us are white, I think there are two science majors max (including myself), we have representatives from American University and other liberal arts schools, and I know at least some of them have parents that are medical doctors or have a doctorate in the arts or humanities. This is my first time outside the United States, but I know that at least five others have spent at least a few weeks outside of the U.S. at some point in their lives. So overall, everyone else is more well-traveled than me.
In general, I usually do not think that my background as a first generation college student affects my interactions with my peers. I think it's a little awkward when someone says that their father is a doctor or that their father has a Ph.D. in Philosophy, but usually, it's just someone that comes up in a casual conversation and they do not expect me to say what my parents do.
I think that I have learned to be independent and I usually do not rely on others when navigating the college system, and I think that is probably also true for learning how to adjust to life abroad. I just need some time and I make the adjustments on my own. I'm sure that the students that have been abroad may be able to adjust easier, but I don't really know if it is that different from my fellow study abroad students.
Blooms in the Baltic
Every summer, phytoplankton – microscopic plant-like organisms – spread across the North Atlantic, with blooms spanning hundreds and sometimes thousands of miles. Nutrient-rich, cooler waters tend to promote more growth among marine plants and phytoplankton than is found in tropical waters. Blooms this summer off Scandinavia seem to be particularly intense.
On July 18, 2018, the Operational Land Imager (OLI) on Landsat 8 acquired a natural-color image of a swirling green phytoplankton bloom in the Gulf of Finland, a section of the Baltic Sea. Note how the phytoplankton trace the edges of a vortex; it is possible that this ocean eddy is pumping up nutrients from the depths.
Though it is impossible to know the phytoplankton type without sampling the water, three decades of satellite observations suggest that these green blooms are likely to be cyanobacteria (blue-green algae), an ancient type of marine bacteria that capture and store solar energy through photosynthesis (like plants).
In recent years, the proliferation of algae blooms in the Baltic Sea has led to the regular appearance of “dead zones” in the basin. Phytoplankton and cyanobacteria consume the abundant nutrients in the Baltic ¬and deplete the oxygen. According to researchers from Finland’s University of Turku, the dead zone this year is estimated to span about 70,000 square kilometers (27,000 square miles).

Weekdays
Weekends
Buses
Food
Daily life here in Costa Rica, at least for me, is not necessarily all that different or much more exciting than daily life in the U.S. The major difference is since my workload is a lot lighter here, I have a lot more free time.
A typical week may play out like this. Every day, I usually get up between 7:30-8:00 am. Even on weekends when I don’t have plans, my body is used to waking up early and I usually never sleep to my alarm. This may be because the sun is always up my 6:00 am and my internal body clock has just adjusted to this. On Monday, I don't have class until 1 pm, but I usually don't get home until 7:30-8:00 pm, which makes Monday my busiest day. I usually spend the first half of the day doing random stuff, unless I have something I need to prepare for a class, such as an exam or presentation. On Tuesday, I have class at 10:00 am until 11:40 am, and I have a break to go back home and eat lunch before I have my other class at 3:00 pm, which usually is a little under two hours.
By Tuesday night, I usually pretty tired (since Monday is always a long day) and I don't do too much since I have no class on Wednesday. This makes Wednesday a day to relax or get a head start on work for Thursday and Friday. Occasionally, I have gone on day trips. For example, one week I went somewhere with my host mom for the day and last week, I went to San José to visit two museums. The rest of my week is really easy class wise, with only one class Thursday and Friday, with both starting at 10:00 am.
On weekends, I've gone on quite a few trips, some sponsored by IFSA and some as a part of a class. Otherwise, I may go a few places with my host parents, do watch, or watch a few things on Netflix.
In order to get around, I usually take the bus. I live in Barva and la Universidad Nacional is in Heredia, so I always need to take the bus to get to and from class. One round trip costs about $0.35, and it can take anywhere from 10-30 minutes for the bus to get from Barva to Heredia or vice versa, but it usually takes about 15-20 minutes. Other buses, to San José for example, cost a bit more, but still under $1 one way usually unless it's a few hour trip. That being said, if you plan out which buses you need to take, it is pretty easy to get around, even if you're used to having a car like me.
With my host family, breakfast usually consists of eggs a mix of rice and beans called gallo pinto. We usually have freshly-squeezed orange juice as well, and my host parents also drink coffee. We sometimes have cereal or an egg sandwich too. Lunch and dinner are usually pretty similar, and almost always include rice and beans (a staple in Costa Rica). Sometimes my host mom needs to make food that's a little bit different for me because I'm a vegetarian. We almost always have either some type of fruit juice, usually made of cas, but sometimes mango, pineapple, or watermelon, or iced tea. I usually like everything my host mom makes. I don't have to do any of my own laundry, which is very different from college in the U.S. If my host mom does not do it, the maid that comes on Mondays and Fridays comes.
Marine Life of the Maritime Provinces, Canada
After months of work and waiting, here is at long last the full MARS commission. MARS (Marine Animal Response Society) is active in the Maritime Provinces of Canada, and is called upon whenever a marine creature is found dead or in distress. These illustrations will be used to educate their volunteers and assist in making species identifications during strandings or at sea.
With 42 separate illustrations, this is my largest project to date - quite a load of work! But it was an absolute pleasure to do. I got to paint animals I have never painted before, as well as revisit some old friends. The diversity of species found in this one area is impressive and made for varied painting.
I’m pretty pleased seeing them all together like this, and I hope you’ll enjoy them too!
Dr. Nancy Foster Scholar Alexandra Avila photographed these Hawaiian spinner dolphins in Hawaiian Islands Humpback Whale National Marine Sanctuary. Spinner dolphins are incredibly gregarious, sometimes gathering in groups of several hundred or more! These dolphins feed at night and return to coastal waters to rest and socialize. Because they rest during the day, it’s important to give them lots of space – would you like someone trying to hang out with you when you’re trying to get some shut-eye?

With Stephen Hawking’s passing, today is a sad day for science. But amongst all his praise and achievements in the fields of physics, for me personally his biggest achievement was making a grand, full life despite the terrible misfortune of being diagnosed with ALS. It would have been easy to become a recluse, embittered with the hand he’d been dealt, a brilliant misanthrope. But this was a man who maintained his sense of humor and refused to be mentally beaten. Three years ago, he told One Direction fans that the theory of alternate universes could provide a reality where Zayn Malik was still in the band. He conducted an interview with John Oliver where his factual, deadpan delivery was funnier than his interviewer, managing the cheekiest grins as he did so. And let us not forget that Stephen Hawking is the only person to have ever portrayed themselves in a Star Trek episode (Next Generation, “Descent, Part 1″), where he appeared alongside actors portraying Einstein and Sir Isaac Newton, whom he proceeded to defeat in poker.
Hawking’s observations on black hole radiation, string theory, alternate universes and artificial intelligence are things that will probably forever remain beyond most of us. But we could all learn a thing or two from his humanity.
Very cool. My lab group also works with Emiliania huxleyi and EhVs.
With only a few days until Valentines day it is my scientific duty to inform you all that if you don't have a valentine yet, an algal cell will be your valentine. They will be assigned automatically and love you with all their chloroplasts. You may not opt out, but a platonic algae-mate will be assigned to those who are not romantically inclined.
Meet your new alBAE 💚💚.
