Experts typically spend thirty minutes to one hour, once a week, answering questions. We ask that volunteers commit to the entire school year, but at times we do make shorter assignments. The Ask an Expert Program is a free online forum where students and parents can ask questions about K-12 science projects. Our team of volunteer experts work together to provide personalized assistance with students who have questions about any phase of their project, from coming up with an idea to analyzing data to displaying results at a science fair. A new analysis of observed temperatures shows the Arctic is heating up more than four times faster than the rate of global warming. The trend has stepped upward steeply twice in the last 50 years, a … Faster warming in the Arctic will be responsible for a global 2C temperature rise being reached eight years earlier than if the region was warming at the average global rate, according to a new modelling study led by UCL researchers.

Comets 103P and 45P suggested that researchers may have been hasty in dismissing all comets as Earth’s water source. From the definition above, it might sound like a microscope is just a kind of magnifying glass. In fact, magnifying glasses do qualify as microscopes; since they have just one lens, they are called simple microscopes. The fancier instruments that we typically think of as microscopes are compound microscopes, meaning that they have multiple lenses.

What is the scientist’s role in society and how do we teach it?

Observations of comet 45P/Honda-Mrkos-Pajdušáková three years later also found abnormally low D/H ratios. Suddenly one, possibly two, comets were carrying Earthlike water. WATER, WATER EVERYWHEREEarth is a wet planet that formed in a dry part of the solar system. How our planet’s water arrived may be a story of big, bullying planets and ice-filled asteroids. Student lab microscopes tend to be brightfield microscopes, meaning that visible light is passed through the sample and used to form an image directly, without any modifications. Slightly more sophisticated forms of light microscopy use optical tricks to enhance contrast, making details of cells and tissues easier to see. Memories change the way nerves exchange signals at points of contact called synapses.

Because of the way these lenses are arranged, they can bend light to produce a much more magnified image than that of a magnifying glass. If memories are consolidated just once, when they are first created, he reasoned, the drug would have no effect on the rat’s memory of the tone or on the way it would respond to the tone in the future. But if memories have to be at least partially rebuilt every time they are recalled—down to the synthesizing of fresh neuronal proteins—rats given the drug might later respond as if they had never learned to fear the tone and would ignore it. If so, the study would contradict the standard conception of memory. The population crashed following climate change about 930,000 years ago, scientists concluded.

We urgently need a better understanding of where, and how, science and technology fit into the cultural and industrial life of the nation. Scientists should become more proactive in providing advice to politicians and policy-makers where proposed new policies involve knowledge they possess from their research. Recently, a crowdsourced science project recovered and digitized these now-declassified meteorological records, rescuing nearly four million observations that span a critical wartime data gap. Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. The same planetary tango that robbed Mars of resources might also explain how icy asteroids pummeled Earth.

Data science

Cluster network of scientific publications in relation to Nobel prizes. Theoretical computer science is a subset of general computer science and mathematics that focuses on more mathematical topics of computing, and includes the theory of computation. A statistician is someone who is particularly well versed in the ways of thinking necessary for the successful application of statistical analysis. Such people have often gained this experience through working in any of a wide number of fields. There is also a discipline called mathematical statistics, which is concerned with the theoretical basis of the subject. Historically, logic has been studied in philosophy and mathematics (since the mid-19th century). More recently, logic has been studied in cognitive science, which draws on computer science, linguistics, philosophy and psychology, among other disciplines.

In short, Nader believes that the very act of remembering can change our memories. The simplified, linear description of the scientific method implies that science concludes … but in reality, scientific conclusions are always revisable if warranted by the evidence. Scientific investigations are often ongoing, raising new questions even as old ones are answered. The scientist’s role should therefore be to interpret evidence for them and bring perspective, particularly where there is a body of evidence pointing in a different direction. It would also be of benefit if the fundamental concepts behind the “scientific method” could be more widely applied to policy-making. Significantly less than two degrees Celsius above pre-industrial times — this is the temperature to which global warming should be limited, according to the Paris Climate Agreement.
