• Defending the Earth from asteroids

    A mere 17-20 meters across, the Chelyabinsk meteor caused extensive ground damage and numerous injuries when it exploded on impact with Earth’s atmosphere in February 2013. To prevent another such impact, researchers use a simple yet ingenious way to spot these tiny near-Earth objects (NEOs) as they hurtle toward the planet.

  • Identifying new way to improve cybersecurity

    With cybersecurity one of the nation’s top security concerns and billions of people affected by breaches last year, government and businesses are spending more time and money defending against it. Researchers have identified a new way to improve network security.

  • Sensing earthquakes in a new way to help improve early warning systems

    Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell the difference between life and death. Researchers demonstrate a new earthquake detection method — their technique exploits subtle telltale gravitational signals traveling ahead of the tremors. Future research could boost early warning systems.

  • Novel compact antenna for communicating where radios fail

    A new type of pocket-sized antenna could enable mobile communication in situations where conventional radios don’t work, such as under water, through the ground and over very long distances through air. The 4-inch-tall device could be used in portable transmitters for rescue missions and other challenging applications demanding high mobility.

  • New sensors can sense and sort troublesome gases

    From astronauts and submariners to miners and rescue workers, people who operate in small, enclosed spaces need good air quality to work safely and effectively. Newly developed electronic sensors can simultaneously detect at least three critical parameters that are important to monitor to ensure human comfort and safety.

  • Accurately predicting harmful space weather’s “killer” electrons

    A new space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth’s outer radiation belt. The model can accurately give a one-day warning prior to a space storm of ultra-high-speed electrons, often referred to as “killer” electrons because of the damage they can do to spacecraft such as navigation, communications, and weather monitoring satellites.

  • Flying cars: automating the skies means playing with our lives

    Recent research suggests that flying cars could eventually be a sustainable way to free up roads. The first models are set to hit our skies in 2019 as personal playthings, while industry sees them as taxis and commuter vehicles of the future. But as Harry Potter’s encounter with the Whomping Whillow reminds us, flying cars can be dangerous. Before futuristic visions of three-dimensional sprawling city traffic can approach reality, there are some serious safety issues that need addressing.

  • New device creates electricity from snowfall

    Researchers and colleagues have designed a new device that creates electricity from falling snow. The first of its kind, this device is inexpensive, small, thin and flexible like a sheet of plastic.

  • Biologically inspired network protection software

    Electrical engineers look to the human immune system for clues on how to best protect digital networks. It’s a concept that’s beginning to be explored more and more by researchers in a variety of fields: What does the human body do well and how can we adapt those mechanisms to improve technology or engineering systems?

  • Why the Great Plains has such epic weather

    From 78 degrees on Tuesday to snow on Wednesday? Swings like this aren’t unusual in the central United States, where weather can quickly shift from one extreme to another. What generates such “big weather” on the Great Plains?

  • Preparing San Francisco for future storms

    The San Francisco Bay Area has been pummeled this winter by storms packed with moisture from atmospheric rivers. San Francisco is partnering with the Berkeley Lab to assess how climate change may influence the intensity of atmospheric rivers and associated precipitation, and how those changes may impact San Francisco and its infrastructure.

  • Flying colors: Assessing the role of flying cars in sustainable mobility

    A new study of the environmental sustainability impacts of flying cars, formally known as electric vertical takeoff and landing aircraft, or VTOLs, finds that they wouldn’t be suitable for a short commute. However, VTOLs—which combine the convenience of vertical takeoff and landing like a helicopter with the efficient aerodynamic flight of an airplane—could play a niche role in sustainable mobility for longer trips.

  • Stern warning: Climate expert emphasizes the fierce urgency of now

    Prominent economist and policymaker Lord Nicholas Stern delivered a strong warning about the dangers of climate change in a talk at MIT on Tuesday, calling the near future “defining” and urging a rapid overhaul of the economy to reach net zero carbon emissions. “The next 20 years will be absolutely defining,” Stern told the audience, saying they “will shape what kind of future people your age will have.”

  • China catching up to the U.S. in innovation

    If China is only a copier, not an innovator, then the competitive threat it poses to advanced economies would be limited. But there is no reason to believe China won’t follow the path of “Asian tigers” that rapidly evolved from copiers to innovators, which poses a serious threat.

  • Detecting, analyzing suspicious activity in surveillance footage

    Traditional surveillance cameras do not always detect suspicious activities or objects in a timely manner. Researchers developed a hybrid lightweight tracking algorithm known as Kerman (Kernelized Kalman filter).
