    The third annual Summer of STEM is emerging as the most ambitious by far for the New York University Polytechnic School of Engineering: Reaching some 1,100 K-12 students and teachers as well as college instructors, it is offering the skills and excitement of science, technology, engineering and mathematics through twenty different programs.

  • We could find aliens any day now: SETI scientists discuss extraterrestrial life hunting

    ET phone Earth! We could be on the verge of answering one of the essential questions of humanity that has captivated our minds for centuries. As we advance in technology the search for extraterrestrial life becomes more sophisticated and promising. But the real frosting on the cake would be finding any signs of an intelligent alien civilization. The Search for Extraterrestrial Intelligence (SETI) project is looking carefully for these signs, listening to the universe that may be full of potential ET signals. Key figures of alien life hunting discuss the ongoing search for extraterrestrial life.

  • Successful test for open-sea pilot connecting power generated from waves, tides, and currents to the grid

    Marine and hydrokinetic (MHK) technologies, which generate power from waves, tides, or currents, are at an early but promising stage of development. Many coastal areas in the United States have strong wave and tidal resources, and more than 50 percent of the U.S. population lives within fifty miles of a coastline, making transmission from these resources more economical. With further progress toward commercialization, MHK technologies could make substantial contributions to our nation’s electricity needs.

  • NASA balances water budget with new estimates of liquid assets

    Many pressing questions about Earth’s climate revolve around water. With droughts and flooding an ongoing concern, people want to know how much water is on the move and where it is going. To help answer those questions, a new NASA study provides estimates for the global water cycle budget for the first decade of the twenty-first century, taking the pulse of the planet and setting a baseline for future comparisons.

  • Countering extremist groups’ social media influence, persuasion

    Social media has become a vital channel for terrorist groups to share news and seduce new members. The recent, notable successes of ISIS in the United States and Europe have demonstrated that terror groups can successfully use this approach to further their agenda of violence. While it gets less attention, social media is equally important for groups that are sharing and communicating information to counter extremist discourse. The problem is, how can those looking to counter the violent ideology of groups like ISIS analyze all the conversations to determine what is a significant danger? How can groups countering violent extremism leverage social media to limit the diffusion of extremist ideology? New research aimed at helping to solve this puzzle.

  • Illinois’s cybersecurity talent to participate in USCC camp & competition

    Next week, Illinois’s top cybersecurity talent, including veterans, will gather at Moraine Valley Community College in Palos Hills, Illinois, to participate in the annual U.S. Cyber Challenge (USCC) Cyber Camp. Throughout the week-long camp, individuals will participate in a variety of classes that cover such subjects as packet crafting and pen testing, and compete in a virtual “Capture the Flag” competition to demonstrate their cybersecurity abilities in a free-form environment.

  • "Keeping America a technological leader": SRC's STEM-supporting initiatives

    SRC, Inc., an R&D company which was established in 1957, has its roots in academia. It regards science, technology, engineering & math (STEM) as the foundation of its business. Over the past decade there have been numerous reports about how the U.S. ranking in science and mathematics education has been declining. There has also been a drop in the number of students majoring in STEM fields. Around 2007, SRC developed its philanthropic focus areas as a way to direct its resources to areas where the company could have the most impact. One of these focus areas is STEM. HSNW talked with Lisa D. Mondello, director of corporate communications and PR at SRC, about the company’s STEM-related initiatives.

  • Using microwave technology to detect concealed weapons

    A team of researchers in Canada and the Ukraine funded by NATO which will be exploring ways to equip soldiers and law enforcement with gear that could detect concealed threats, such as guns and explosive devices, used by terrorists and security threats. The three-year project, which launched 1 July, will study how microwave radar signals sent from either rigged vests or tripods could detect trouble as far as fifteen meters away and send early warning signals of pending danger. These devices could be used anywhere from borders to airports to crowded public events to bars and hotels.

  • Terahertz sensor detects hidden objects faster

    A new type of sensor, which is much faster than competing technologies used to detect and identify hidden objects. Called “Q-Eye,” the invention senses radiation across the spectrum between microwaves and infra-red, known as the Terahertz (THz) region of the spectrum — a goal that has challenged scientists for over thirty years. It works by detecting the rise in temperature produced when electromagnetic radiation emitted by an object is absorbed by the Q-Eye sensor, even down to the level of very small packets of quantum energy (a single photon).

  • Producing fuel from Canada oil sands emits 20 percent more CO2 than from U.S. crude

    In 2013, the oil industry was producing nearly two million barrels per day from Canadian oil sands. By 2030, that number is expected to rise to just over 4.8 million barrels per day. As the United States takes stock of its greenhouse gas emissions, scientists report that the current oil sands production of fuels from “well-to-wheels” releases about 20 percent more carbon dioxide into the atmosphere than making gasoline and diesel from conventional crudes.

  • Mass killings, school shootings are contagious

    On average, mass killings involving firearms occur approximately every two weeks in the United States, and school shootings occur on average monthly. Mass killings — events with four or more deaths — and school shootings create a period of contagion that lasts an average of thirteen days. Roughly 20 to 30 percent of such tragedies appear to arise from contagion. “The hallmark of contagion is observing patterns of many events that are bunched in time, rather than occurring randomly in time,” says a researcher.

  • U.S. military looking for ways to lighten the load infantrymen carry on missions

    Typically, an infantryman on a three-day mission will carry 80 to 100 pounds and often more, when the weight of the weapon, night vision equipment, extra batteries to power the advanced equipment, and body armor are added to the burden. When it comes to a one day combat patrol, the weight carried drops to a “mere” sixty-five pounds.The effects of such a burden not only slow the warfighters down, they reduce agility and my result in log-term harm. The military is looking for ways to lighten the load.

  • Our new anti-earthquake technology could protect cities from destruction

    Protecting cities from earthquakes is still a grand challenge that needs addressing, as recent disasters in Nepal, Japan, Haiti, and Chile confirm. Although significant progress has been made in understanding seismic activity and developing building technology, we still don’t have a satisfactory way of protecting buildings on a large scale. This is a serious problem, since large numbers of buildings that don’t have built-in protection exist in earthquake zones, particularly in developing countries where replacing them or introducing stricter — and more expensive — building codes aren’t seen as an option. Researchers have designed a novel vibrating barrier (ViBa) to reduce the vibrations of nearby structures caused by an earthquake’s ground waves. The device would be buried in the soil and detached from surrounding buildings, and should be able to absorb a significant portion of the dynamic energy arising from the ground motion with a consequent reduction of seismic response (between 40-80 percent).

  • If global warming is left unchecked, fish will have to find new habitats -- or perish

    The goods and services our oceans provide are valued at hundreds of billions of dollars per year. A new study assessed the impact of climate change on marine and coastal ecosystems, ocean chemistry, tourism, and human health. The study specifically analyzed how warming will impact fisheries and the global economic gains we receive from these fisheries. It found that Climate change is forcing fish out of their current habitats and into cooler waters and many more species will soon be affected if climate goals are not met. “From looking at the surface of the ocean, you can’t tell much is changing,” said one researcher. “The oceans are closely tied to human systems and we’re putting communities at high risk.”
