Different types of microscopes differ in their magnification and resolution. More complex compound microscopes may not produce an inverted image because they include an additional lens that “re-inverts” the image back to its normal state.
A major government assessment lays out both the far-reaching perils of global warming and the cost-effective fixes that are available today. In one of Yellowstone National Park’s most well-known attractions, researchers discovered an extraordinary diversity of microbial life. A simulation suggests that fine particles played a stronger role in cooling the planet and stalling photosynthesis after an asteroid impacted the Earth. The chance finding in a Japanese university’s greenhouse could help researchers find ways to control agricultural pests or even insects that spread disease. In the Cyclops Mountains in the Indonesian part of the island of New Guinea, Oxford scientists and local guides made a series of spectacular discoveries. A new study suggests that explosive events in space have the potential to temporarily switch off the natural shield that protects us from harmful solar radiation. Repeated bits of the disease-causing gene pile up in some brain cells.
The core of science
Botany, also called plant science, plant biology or phytology, is the science of plant life and a branch of biology. Nowadays, botanists study approximately 410,000 species of land plants of which some 391,000 species are vascular plants , and approximately 20,000 are bryophytes. Microbiology is the study of microorganisms, those being unicellular , multicellular , or acellular . Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology and parasitology. In this context the word systems is used to refer specifically to self-regulating systems, i.e. that are self-correcting through feedback. Self-regulating systems are found in nature, including the physiological systems of our body, in local and global ecosystems, and climate.

The study was supported by the Natural Environment Research Council , the European Space Agency , and the Canada 150 Research Chairs Program. The Arctic is thought to have warmed by 2.7C since the pre-industrial era, and this warming is believed to have accelerated since the start of the 21st century. NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery. Most of the pages remained in paper form in the National Archives and Records Administration in Washington, D.C., Teleti explains. To access the data they contain, he and his colleagues worked with archivists to photograph and scan each page. For decades, those logbooks were classified to protectmilitarysecrets. But in 2017, the National Declassification Centerreleased nearly 200,000 pagesof World War II era material, including many from those logbooks.
Past records suggest that sea surface temperatures during 1941 to 1945 were notably warmer than the five years before and after, but the uncertainty in the data is several times higher during the war than before or after it. No climate model has been able to reproduce this temporary spike in global mean sea surface temperature, Chan says. The ship logs can help depict the climate at that time and improve the models’ accuracy. In total, 4,050 volunteers helped digitize more than 630,000 records from more than 28,000 logbook images from 19 ships. Each record contained multiple types of weather observations, like wet- and dry-bulb temperature, wind speed and direction, barometric pressure, sea surface temperature, visibility and overall weather conditions. In total, the project rescued 3.7 million meteorological observations that span from 1941 to 1945.
In reply to Lord Kelvin’s attacks, the geologists used two principal lines of reasoning. One referred to the depth of the sediments and the time they would have taken to accumulate; the other referred to the salinity of the oceans, compared with the rate at which rivers are supplying them with sodium salts. In hindsight, both theories were deeply misguided, for similar reasons.
Telescopes are time machines
If two bacterial cells were very close together on a slide, they might look like a single, blurry dot on a microscope with low resolving power, but could be told apart as separate on a microscope with high resolving power. This picture isn’t a plain light micrograph; it’s a fluorescent image of a specially prepared plant where various parts of the cell were labeled with tags to make them glow. However, this kind of cellular complexity and beauty is all around us, whether we can see it or not.

As parsimonious as the evidence allows: Different ways of seeing color
Among the many questions that Nader is now pursuing is whether all memories become vulnerable when recalled, or only certain memories under certain circumstances. Later the researchers asked all the students what they had seen—a stop sign or yield sign? Students who’d been asked a misleading question were more likely to give an incorrect answer than the other students. In the following days, Nader recalls, he passed through subway stations where walls were covered with notes and photographs left by people searching desperately for missing loved ones. He has a Bachelor of Arts in Biochemistry from Columbia University, and a Ph.D. in Molecular and Cell Biology from the University of California, Berkeley. When physically separated from his keyboard, he tends to seek out a bicycle, or a scenic location for communing with his hiking boots.
The project is to use generative AI to bring out children’s creativity by using storytelling. He is working on the part of the research that controls generative AI prompts to be emotionally safe and creative for children. Seungwook Lee is part of a research project in BAIC that questions what the right way to use Generative AI in future generations is. Larissa Schwartz is both part of BAIC and the ATLAS Institute. Schwartz is a professional graphic designer, and was previously a visual arts and design instructor for public education in Denver and Houston.
