This three-panel figure is an infographic showing how carbon and oxygen isotope ratios, temperature, and carbonate sediments have changed during the Palaeocene-Eocene Thermal Maximum. The figure caption provides sources to scientific articles from which this data was derived. A graphic visualization from the Intergovernmental Panel on Climate Change shows the rapid decrease in carbon isotope ratios that is indicative of a large increase in the atmospheric greenhouse gases CO2 and CH4, which was coincident with approximately 5C of global warming.

In this short video, atmospheric scientist Scott Denning gives a candid and entertaining explanation of how greenhouse gases in Earth's atmosphere warm our planet.

Students use a hurricane tracking map to measure the distance from a specific latitude and longitude location of the eye of a hurricane to a city. Then they use the map's scale factor to convert the distance to miles. They also apply the distance formula by creating an x-y coordinate plane on the map. Students are challenged to analyze what data might be used by computer science engineers to write code that generates hurricane tracking models. Then students analyze a MATLAB® computer code that uses the distance formula repetitively to generate a table of data that tracks a hurricane at specific time intervals. Students come to realize that using a computer program to generate the calculations (instead of by hand) is very advantageous for a dynamic situation like tracking storm movements. Their inspection of some MATLAB code helps them understand how it communicates what to do using mathematical formulas, logical instructions and repeated tasks. They also conclude that the example program is too simplistic to really be a useful tool; useful computer model tools must necessarily be much more complex.

This short investigation from Carbo Europe explores how temperature affects the solubility of carbon dioxide in water.

Limiting the debilitating consequences of ageing is a major medical challenge of our time. Robust pharmacological interventions that promote healthy ageing across diverse genetic backgrounds may engage conserved longevity pathways. Here we report results from the Caenorhabditis Intervention Testing Program in assessing longevity variation across 22 Caenorhabditis strains spanning 3 species, using multiple replicates collected across three independent laboratories. Reproducibility between test sites is high, whereas individual trial reproducibility is relatively low. Of ten pro-longevity chemicals tested, six significantly extend lifespan in at least one strain. Three reported dietary restriction mimetics are mainly effective across C. elegans strains, indicating species and strain-specific responses. In contrast, the amyloid dye ThioflavinT is both potent and robust across the strains. Our results highlight promising pharmacological leads and demonstrate the importance of assessing lifespans of discrete cohorts across repeat studies to capture biological variation in the search for reproducible ageing interventions.

In this activity, college level students learning fundamental concepts in Environmental Chemistry apply their knowledge either in carrying out a research project or in designing a hands-on mini-workshop with the key objective of teaching middle-school students topics relevant to water quality and stormwater. College-level students also take part in a restoration activity on a local watershed three miles away, working side by side with the middle-school students and the members of the community.

The project aims to bring together middle-school students, college-level students, and local citizens on a monitoring and restoration program of a local creek; improve the public's understanding and engagement on local environmental issues such as stormwater; improve the educational experience of both middle-school and college-level students; and motivate middle-school students to pursue further education in the field of science. This project is an example of environmental education bringing together two different levels of students, as well as the community as a whole.

Essential Accessibility for Everyone

Short Description:
With raised awareness and accessibility laws emerging around the world, understanding what inclusive access to the Web means is becoming necessary knowledge for anyone who produces digital content. Much of the current information on Web accessibility requires some technical understanding, and may be difficult to consume for the average person. The instruction here will “interpret” the W3C Web Content Accessibility Guidelines (WCAG 2.1), to make it easier to understand for a general audience. You will have an opportunity to experience barriers firsthand, then experience that content with the barriers removed, developing a practical understanding of web accessibility.

Students act as engineers to apply what they know about how circuits work in electrical/motorized devices to design their own battery-operated model motor vehicles with specific paramaters. They calculate the work done by the vehicles and the power produced by their motor systems.

In this learning activity, students analyze an actual dataset of the influence of temperature on tree growth. They use mathematical and statistical concepts like slope equations and lines of best fit to determine the relationship. They are then asked to make predictions about future tree growth under different greenhouse gas emissions, interpreting data from climate models to make these predictions.

This video contains a visualization and explanation of the Arctic sea ice and how it has changed over the 25 years. In September 2012, the National Snow and Ice Data Center recorded the lowest extent of Arctic sea ice. The video discusses the climate importance of ice thickness, reflective properties, and self-reinforcing feedback mechanisms.

This 32-year-old man without specific underlying disease suffered from intermittent headache for more than half a month. The pain was localized over left side temporal area and then transferred to left occipital area. It could be relieved with acetaminophen. However a severe headache episode, with repetitive vomiting, aroused him from sleep early one morning. He was sent to the emergency department with stable vital signs and clear consciousness. On examination, there was no anisocoria, limbs weakness, dysphasia, dysarthria, or palsy of cranial nerves.

A 35-year-old woman presented for neurological evaluation after a single episode of speech disruption consisting of word finding difficulty and a partial motor seizure followed by one hour of confusion. A head MRI scan was performed, which showed a 2.7 by 2.0 by 2.5 cm dural-based contrast enhancing lesion along the left posterior temporal lobe (Figure 1). An EEG at the time of presentation was negative, but the patient was placed on prophylactic Dilantin therapy. She was referred for neurosurgical evaluation, and a recommendation was made for surgical resection. A left parietal-temporal craniotomy was performed to resect the tumor. At surgery, a firm dural-based lesion was encountered with no evidence of brain invasion or involvement, and a gross total resection was performed. The patient tolerated the procedure well, and was discharged home on postoperative day three. The patient had no further seizures or episodes of speech difficulty, and was tapered off of her anticonvulsants six months following surgery, with a second EEG negative at that time. Follow-up MRI scans at 6 and 12 months showed no evidence of tumor recurrence, and she continues to have a normal neurological exam.

A 69-year-old woman presented with a 2-month history of progressive bilateral leg weakness and gait difficulty. On examination, the patient had diffuse lower extremity weakness and hypesthesia of the left leg. Magnetic resonance imaging revealed a 2.9-cm, extradural, soft tissue mass at the T5-6 level, with spinal cord compression; the mass was hypointense on a T1-weighted image (Figure 1) and hyperintense on a T2-weighted image (Figure 2). The tumor was a relatively well-demarcated epidural mass with focal invasions into both facet joints. Intraoperative examination showed a neoplasm with clear and granular cell morphologies displaying solid, papillocystic, and follicular patterns. Postoperative 18F-fluoro-2-deoxy-D-glucose positron emission tomography-computed tomography (CT) and neck CT failed to identify a primary tumor or any other lesions.

A 6-years-old African American girl presented with severe headache for several days associated with vomiting, neck stiffness, fever, and unsteady gait. Physical examination was otherwise unremarkable. She was recently treated for otitis media approximately one week prior to admission. Mother reported that the patient had frequent headaches and incontinent of bowel and bladder during the past year. A lumbar puncture showed high CSF protein but no signs of infection. Computer Tomography (CT) (Figure 1) and Magnetic Resonance Imaging (MRI) of the brain (Figure 2) showed obstructive hydrocephalus with a 2.3 cm non-enhancing pineal region mass attached to the tectum. MRI of the spinal cord at this time was negative for metastatic disease (Figure 3).
