A starting material was prepared as a powdered mixture of regent grade chemicals of Mg(OH)2 (45.11 wt.%), SiO2 (38.02 wt%), Al(OH)3 (5.48 wt.%) and 57Fe enriched Fe2O3 (11.38 wt.%). Single crystals of hydrous phase-D were synthesized using a 1200-ton Kawai-type multi-anvil high-pressure apparatus at Bayerisches Geoinstitut, University of Bayreuth, Germany . Tungsten carbide anvils with 3 mm truncated edge lengths were used in combination with a 5 wt% Cr2O3-doped MgO octahedral pressure medium with a 7-mm edge length. A cylindrical LaCrO3 heater was located at the center of the pressure medium. The starting material was packed in a welded platinum capsule. The sample capsule was inserted in an MgO capsule and put at the central part of the heater. Sample temperature was monitored at the central part of the outer surface of the Pt capsule using a W-3%Re/W-25%Re thermocouple. Pressure effect on electromotive force of the thermocouple was ignored.

The new graduate program in the Biology of Extreme Environments is the first of its kind both in Italy and in Europe, and aims to prepare the next generation of biologists that will work to unravel the role of extreme environments in controlling planet habitability, contribute to biogeochemical cycling, provide new biotechnological resources and contribute to space exploration. To reach these goals we are training the explorers of tomorrow, integrating multiple disciplines, focusing on hard to ask big questions and providing hand-on training and research experience. The new program has found extensive support from National and International biotechnological and biomedical companies, research institutes and space agencies, including the International Society for Extremophiles, the Earth-Life Science Institute, the Agenzia Spaziale Italiana and the NASA Astrobiology program.

Rapid population growth, associated with social and technological progress, and the constant demand for new natural resources, requires a greater understanding of genetic, biochemical and biotechnology of natural environments for the purpose of sustainable exploitation of resources. In this sense, the extreme environments, represent one of the major reservoirs of biological and microbial genetic diversity in the planet, and constitute areas of great economic interest also due to the abundance of materials rare raw materials and the possibility of their use for recreational purposes. The biotechnological versatility of enzymes extracts from extremophilic organisms of polar, volcanic and hydrothermal environments, the exploitation of metals rare and the use of thermal springs for recreational / curative purposes since ancient times, constitute examples that underline the importance of extreme environments in our social and cultural context. The extreme environments are also fundamental in studies on the birth and evolution of life on earth, e they provide unique opportunities for the development of technologies aimed at future exploration and colonization of extraterrestrial environments. The extreme environments, in fact, have areas similar to those that humans do will find exploring and colonizing in the years to come, starting with the 2024 moon missions and those on Mars planned for the next decade.

The master program is organized in two curricula, focusing on the sustainable use of the biological resources present in extreme environments and in the use of extreme environments as a proxy for astrobiological investigations. The two curricula are organized around common and curricula-specific classes over the course of two years. Students are required to perform a research master thesis of a minimum duration of ten months that provides them with a unique opportunity to perform research in the selected topic of their choice. The faculty is composed of faculty members from the Department of Biology, home of the new program, the Department of Earth, Environmental and Resources Sciences (DiSTAR) and the Department of Chemistry. Our faculty are daring, visionary thinkers, actively engaged in research at the frontiers of the subjects they are teaching, creating intellectual excitement and providing cutting-the-edge insight to the students. The new program, currently pending approval, is entirely in English, and will start in the fall of 2021.

Based on individual goals, students tailor their undergraduate experience in the major by applying to one of the two colleges, enrolling in variations of core major requirements, and selecting one of 14 concentrations in the major. Biological Sciences majors develop an excellent foundation in biology, chemistry, physics, and mathematics and complete advanced courses in genetics and biochemistry before delving into upper-level biology courses to complete their concentration. Over 70% of biology majors participate in research during their undergraduate academic careers at Cornell. Students who wish to graduate with honors must apply to the Honors Program at the end of their junior year, maintain a minimum 3.0 cumulative grade point average, and write a thesis based on original research conducted under the direct guidance of a Faculty members in biology are actively engaged in research at the frontiers of the subjects they are teaching, creating intellectual excitement and vitality that give students a genuine feeling of participation in scholarly undertakings. In the classroom, undergraduates hear about important new discoveries, and they are also encouraged to be directly involved in this discovery by pursuing an independent research project. Cornell undergraduates are exposed to a broad diversity of biological problems and challenged to use a variety of investigative approaches to develop solutions.

Laura Streminsky, a sophomore biology major on the pre-med and pre-PA track, and an ethical vegan, found herself dismayed when she discovered that she would have to perform an animal dissection on a rat and a worm for her BIO 204 course.

At the time, Routh was a sophomore at Stony Brook who wanted to pursue a degree in biochemistry. As a vegetarian and animal rights activist, Routh refused to participate in an animal dissection for an introductory biology course.

In fact, a study from the International Journal of Environmental & Science Education which involved science and biology teachers from Ontario secondary schools revealed that 87.5% of these teachers believed that animal dissection is an important tool in teaching biology.

Well done reporting on this. Veganism is an extremely common and increasingly popular life choice. Students should absolutely be supported by this. At the very least, it is completely inappropriate for professor to treat a student like this.

Dissection is not needed. A better alternative is to learn anatomy by viewing images such as MRI or CT images or photographic anatomical images. This experience closely duplicates how anatomy is used in the practice of healthcare. Stony Brook needs to enter the 21st century and modernize its teaching of biology.

The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience.

These deaths will not be offset by the smaller reduction in cold-related deaths projected in the winter months.[1] However, adaptive responses, such as wider use of air conditioning, are expected to reduce the projected increases in death from extreme heat.[1]

Exposure to extreme heat can lead to heat stroke and dehydration, as well as cardiovascular, respiratory, and cerebrovascular disease.[3][4] Excessive heat is more likely to affect populations in northern latitudes where people are less prepared to cope with excessive temperatures. Certain types of populations are more vulnerable than others: for example, outdoor workers, student athletes, and homeless people tend to be more exposed to extreme heat because they spend more time outdoors. Low-income households and older adults may lack access to air conditioning which also increases exposure to extreme heat. Additionally, young children, pregnant women, older adults, and people with certain medical conditions are less able to regulate their body temperature and can therefore be more vulnerable to extreme heat.[1]

Particulate matter is the term for a category of extremely small particles and liquid droplets suspended in the atmosphere. Fine particles include those smaller than 2.5 micrometers (about one ten-thousandth of an inch). Some particulate matter such as dust, wildfire smoke, and sea spray occur naturally, while some is created by human activities such as the burning of fossil fuels to produce energy. These particles may be emitted directly or may be formed in the atmosphere from chemical reactions of gases such as sulfur dioxide, nitrogen dioxide, and volatile organic compounds.

Increases in the frequency or severity of some extreme weather events, such as extreme precipitation, flooding, droughts, and storms, threaten the health of people during and after the event.[1] The people most at risk include young children, older adults, people with disabilities or medical conditions, and the poor. Extreme events can affect human health in a number of ways by:

Vectorborne diseases are illnesses that are transmitted by disease vectors, which include mosquitoes, ticks, and fleas. These vectors can carry infectious pathogens, such as viruses, bacteria, and protozoa, from animals to humans. Changes in temperature, precipitation, and extreme events increases the geographic range of diseases spread by vectors and can lead to illnesses occurring earlier in the year.

West Nile virus is maintained in transmission cycles between birds (the natural hosts of the virus) and mosquitoes. Human infections can occur from a bite of a mosquito that has previously bitten an infected bird. Warmer winters, longer frost-free season, and earlier spring arrival may influence the migration patterns and fledgling survival of birds that are the natural host of West Nile virus. In addition, rising temperature, changing precipitation patterns, and a higher frequency of extreme weather events are likely to influence the distribution and abundance of mosquitoes that transmit West Nile virus.
