2014 was Earth’s warmest year on record; climate markers show global warming trend
In 2014, the most essential indicators of Earth’s changing climate continued to reflect trends of a warming planet, with several markers such as rising land and ocean temperature, sea levels, and greenhouse gases — setting new records. The report’s climate indicators show patterns, changes, and trends of the global climate system. Examples of the indicators include various types of greenhouse gases; temperatures throughout the atmosphere, ocean, and land; cloud cover; sea level; ocean salinity; sea ice extent; and snow cover. “The variety of indicators shows us how our climate is changing, not just in temperature but from the depths of the oceans to the outer atmosphere,” said Thomas Karl, director of the National Oceanic and Atmospheric Administration’s (NOAA) National Centers for Environmental Information.

Millions displaced as a result of climate-related disasters, building in hazard-prone areas
In the last seven years, an estimated one person every second has been displaced by a disaster, with 19.3 million people forced to flee their homes in 2014 alone. In 2014, 17.5 million people were forced to flee their homes by disasters brought on by weather-related hazards such as floods and storms, and 1.7 million by geophysical hazards such as earthquakes. Climate change is expected to exacerbate the situation in the future, as severe weather hazards become more frequent and intense. Man-made factors — such as rapid economic development, urbanization, and population growth in hazard-prone areas – have also contributed to the the overall increase in disaster displacement.

Accelerometers embedded in ear tags detect disease in beef cattle
A smartphone switches its orientation from portrait to landscape depending on how it’s tilted. A car’s airbags inflate when it senses collision forces. By detecting earth’s vibrations, a computer can measure the magnitude and aftershocks of an earthquake. These technologies are made possible by accelerometers — small, electromechanical devices that measure acceleration. The devices are able to detect the most sensitive of motions, from the number of steps taken during a morning walk to the number of jaw movements during a heifer’s morning meal. In fact, some dairy producers use these devices to measure feed intake, detect heat and notably, identify sick animals.

IAEA uses nuclear detection techniques to help measure climate change effects
The International Atomic Energy Agency (IAEA) is responsible for monitoring compliance with the Nuclear Non-proliferation Treaty (NPT) – but the detection technologies it uses to detect illicit nuclear activities are also helpful in tracking and quantifying the effects of climate change. Nuclear techniques offer substantial advantages over conventional techniques for measuring climate change impact. “Stable isotope analyzers let us monitor agricultural processes as they happen. They allow us to quantify carbon capture and emission patterns of farming practices, enabling us to find ways to improve them,” explained one expert.

Detecting illegal, designer drugs from a single fingerprint
An innovative technology can detect the presence of a range of illegal and designer drugs from a single fingerprint, which could be a valuable new tool in bringing drug dealers and other criminals to justice. The technology, known as Matrix Assisted Laser Desorption Ionization Mass Spectrometry Imaging (MALDI-MSI), can detect the presence of cocaine, THC (the chemical present in marijuana), heroin, amphetamine and other designer drugs from a fingerprint.

DHS S&T licenses third cybersecurity innovation for commercialization
The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) yesterday announced that another cybersecurity technology has been licensed for commercialization. This is S&T’s third technology that has successfully gone through the Transition to Practice (TTP) program and into the commercial market. The Network Mapping System (NeMS), developed by Lawrence Livermore National Laboratory, is a software-based tool that tells users what is connected to their network so that they know what needs to be protected.

ONR helps at-risk, underrepresented youth prepare for STEM opportunities
Bureau of Labor Statistics data suggest that the U.S. economy will annually create 120,000 new jobs requiring a bachelor’s degree in computer science by the end of the decade. However, only 51,000 degrees in that field are awarded each year. An innovative program sponsored by the Office of Naval Research (ONR) will open the door to professional career opportunities for at-risk and historically underrepresented youth through training in the fields of science, technology, engineering, arts, and mathematics (STEAM).

Climate change a security risk second only to terrorism: Aussie defense report
The Australian government’s energy White Paper made headlines for its reluctance to mention the term “climate change” — but a forthcoming defense White Paper does not share these reservations. A report on community consultations conducted by the authors of the defense White Paper highlights the consequences of climate change, extreme weather events, and environmental pressures as a significant security risk for Australia – second only to the risks posed by terrorism.

RoboBoats compete for water supremacy
In a race for points, honor and cash, sixteen teams — from the United States and as far away as Indonesia, Taiwan, and South Korea — hit the water with custom-built autonomous surface vehicles (ASVs) at the eighth annual RoboBoat Competition, held 7-12 July in Virginia Beach, Virginia. The competition is an autonomous robotics contest where teams put their student-built ASVs through a series of challenges.

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.
