C lassrooms full of crying students. That's how the scene is often described. In November 2005, at Kalamazoo Central High School in Michigan, every classroom was full of teary-eyed students— jubilant , but teary-eyed. They had good reason to be happy. The vice-principal had just announced over the P.A. system that anonymous benefactors would be paying the students' college tuition— all of the stu
Americans tend to think of colleges as falling somewhere on a vast hierarchy based largely on their status and brand recognition. At the top are the Harvards and the Stanfords with their celebrated faculty, groundbreaking research, and perfectly manicured quads. Toward the bottom are the chronically underfunded community colleges and obscure state schools where part-time students and drab buildin
B efore the automobile , before the Statue of Liberty, before the vast majority of contemporary colleges existed, the rising cost of higher education was shocking the American conscience: "Gentlemen have to pay for their sons in one year more than they spent themselves in the whole four years of their course," The New York Times lamented in 1875. Decadence was to blame, the writer argued: fancy s

Current federal safety regulations for small distribution systems used for propane and other liquefied petroleum gases (LPGs) should be improved for clarity, efficiency, enforceability, and applicability to risk, says a new report from the National Academies of Sciences, Engineering, and Medicine. Because compliance with the federal regulations is not enforced consistently by states, there is litt
Three thousand litres of water – that is the amount needed to produce the food each British person eats every day. This is according to a new study into the "water footprint" of diets in Western Europe, conducted by the European Commission and published in Nature Sustainability.
Let's be honest, launching things into space with rockets is a pretty inefficient way to do things. Not only are rockets expensive to build, they also need a ton of fuel in order to achieve escape velocity. And while the costs of individual launches are being reduced thanks to concepts like reusable rockets and space planes, a more permanent solution could be to build a Space Elevator.
One of the key elements of Earth's climate system is the cryosphere – the many forms of ice found on Earth.

Chinese auto sales fell for a second month in August, an industry group reported Tuesday, adding to signs of economic malaise amid a worsening tariff battle with Washington.
Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Physicists from Leiden University have now found that the charging process of ionic liquids depends purely on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential.
The smallest amount of light you can have is one photon, so dim that it's pretty much invisible to humans. While imperceptible, these tiny blips of energy are useful for carrying quantum information around. Ideally, every quantum courier would be the same, but there isn't a straightforward way to produce a stream of identical photons. This is particularly challenging when individual photons come f
The Arctic is rapidly warming, with stronger effects than observed elsewhere in the world. The Arctic regions are particularly important with respect to climate change, as permafrost soils store huge amounts of the Earth's soil carbon (C). Warming of Arctic soils and thawing of permafrost can have substantial consequences for the global climate, as the large C stored in soils could be released to

Researchers from the group of GESPLAN at Universidad Politécnica de Madrid have applied the Working with People methodology to rethink sustainability, resilience and rural development in Europe.
Ketamine works as an antidepressant at least in part by activating the brain's opioid system, new research reports. The finding overturns previously held beliefs that the drug's antidepressant effects stemmed solely from its impact on the glutamate system. These beliefs led to the widespread use of ketamine to treat depression and spurred the development of glutamate-blocking drugs for use as ant
A team of researchers at the University of California has discovered adaptations made by a species of beetle to survive in different geographic locations.

Japanese and US researchers developed an advanced model to assess the ability of black carbon particles to absorb sunlight and contribute to global warming. The model achieved higher sensitivity than obtained by previous models because it considered both particle size and the complex mixing states of black carbon in air. This advanced model will aid in the assessment of the effectiveness of removi
R ainfall in Cape Town is a dramatic affair. In the winter wet season, ominous clouds and strong winds rumble in from the northwest, carrying with them the life-saving moisture of the Atlantic Ocean and dumping it in cold buckets on the city bowl. For days at a time, storms batter and flood the city and surrounding areas, so much so that the region's first Portuguese moniker was Cabo das Tormenta
As Hurricane Florence tracks toward the East Coast with predicted windspeeds up to 150 mph when it makes landfall Thursday, storm prognosticators are busy trying to forecast its effects for local residents. But one William & Mary ornithologist has his own predictions on what Florence will mean for birds and birders.
Low-severity wildland fires and prescribed burns have long been presumed by scientists and resource managers to be harmless to soils, but this may not be the case, new research shows. According to two new studies, low-severity burns cause damage to soil structure and organic matter in ways that are not immediately apparent after a fire.
Answers to treating muscular dystrophies could lie in better understanding muscle repair–which resembles a delicate cellular dance choreographed by special cells called fibro-adipogenic progenitors (FAPs). Now, scientists at Sanford Burnham Prebys Medical Discovery Institute (SBP) have revealed that FAPs don't have just one identity–but several distinct identities that emerge during key stages o

The ecosystem of the Tibetan Plateau (often referred as the "third pole of the Earth") is highly susceptible to climate change. Using precipitation and temperature records along with Normalized Difference Vegetation Index (NDVI) data, Dr. Ting Hua from the Northwest Institute of Eco-Environment and Resources and Prof. Xunming Wang from the Institute of Geographic Sciences and Natural Resources Res
Pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from predators. There is no recognisable benefit for the pteropod. On the contrary, they starve: Captured between the amphipod's legs, they are unable to feed. Biologists working with Dr. Charlott
For the past 12 years, I've offered a two-hour sexual-harassment-prevention course to supervisors at corporations and churches, schools and charities, police departments and law firms. I've talked about sexual harassment in sweltering community centers and classrooms that smelled of feet, hushed chapels, and posh executive boardrooms. I've been met with disconcerting enthusiasm and glaring hostil
It was long thought that DNA, together with the genes encoded in it, determined genetic destiny. But equally important is coordinating when genes are turned on and off. In fact, the regulation of gene expression defines life by allowing organisms to react to their surroundings rather than being static automatons. As even the smallest organisms like bacteria have many genes, coordinating their expr
The GTPases constitute a very large protein family, whose members are involved in the control of cell growth, transport of molecules, synthesis of other proteins, etc. Despite the many functions of the GTPases, they follow a common cyclic pattern (Figure 1). The activity of the GTPases is regulated by factors that control their ability to bind and hydrolyse guanosine triphosphate (GTP) to guanosin
The evaluation of very large amounts of data is becoming increasingly relevant in ocean research. Diving robots or autonomous underwater vehicles that carry out measurements independently in the deep sea can now record large quantities of high-resolution images. To evaluate these images scientifically in a sustainable manner, a number of prerequisites have to be fulfilled in data acquisition, cura
