• Warning: Objects in Driverless Car Sensors May Be Closer Than They Appear

    Researchers have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensors into believing nearby objects are closer (or further) than they appear without being detected.

  • As Sea Levels Rise, Coastal Megacities Will Need More Than Flood Barriers

    Sea level rise is expected to worsen in the next few decades, especially for many of the world’s largest cities in lower and middle income countries of Africa, Asia and Latin America. These cities are already improving their infrastructure. But most of the focus remains on big engineering solutions (like flood walls and embankments) rather than a more holistic plans.

  • CO2 Could Be Stored Below Ocean Floor

    Climate change is one of the most pressing challenges facing humanity. To combat its potentially catastrophic effects, scientists are searching for new technologies that could help the world reach carbon neutrality. One potential solution that is drawing growing attention is to capture and store carbon dioxide (CO2) emissions in the form of hydrates under ocean floor sediments.

  • War in Ukraine Could Cut Global Supply of Essential Elements for Making Green Technology

    The EU imports 40 percent of its natural gas from Russia, and nearly half of the five million barrels of crude oil Russia exports daily go to Europe. Decisive action by major economies to reduce coal, oil and gas imports from one of the world’s largest sources could accelerate the transition to green energy globally. But there’s a catch. Disruption to the supply of critical metals and other materials caused by the war in Ukraine could stall the roll-out of alternative technologies.

  • Electric Truck Hydropower: Flexible Solution to Hydropower in Mountainous Regions

    Mountain regions have a large potential for hydropower that cannot be harnessed effectively by conventional technologies. Researchers developed an innovative hydropower technology based on electric trucks that could provide a flexible and clean solution for electricity generation in mountainous regions.

  • Armored Transformer Barrier Protects Electric Power Grid

    A 2013 sniper attack on an electric power substation in Northern California, which caused more than $15 million in damages and destroyed 17 transformers, led researchers to develop a novel protective solution: the Armored Transformer Barrier system.

  • A Systems Approach to Cybersecurity

    The frequency and severity of cyberattacks on critical infrastructure is a subject of concern for many governments, as are the costs associated with cyber security, making the efficient allocation of resources paramount. A new study proposes a framework featuring a more holistic picture of the cyber security landscape, along with a model that explicitly represents multiple dimensions of the potential impacts of successful cyberattacks.

  • Last-Minute Defense Against an Asteroid: Obliterating It Before Impact

    Scientists say that pulverizing a threatening incoming asteroid into tiny pieces is our best bet to protect ourselves from an asteroid on short notice.

  • Researchers Show They Can Steal Data During Homomorphic Encryption

    Homomorphic encryption is considered a next generation data security technology, but researchers have identified a vulnerability that allows them to steal data even as it is being encrypted.

  • Insect-Inspired Robots Can Monitor Hard-to-Reach Spots

    There aren’t many spaces that are off-limits to an insect. Researchers have created tiny bug-inspired robots that can carry out tasks in hard-to-reach spaces and inhospitable environments.

  • Computer Security Researchers Aim to Prevent Tech Abuse

    Tech abuse often exists within a larger web of harm. Assailants can abuse their victims through tech including spyware, also known as stalkerware, and through inappropriate use of location-tracking features in phones and other devices. They harass their former partners on social media, hack into email accounts, and more. Researchers have created a new approach to helping survivors of domestic abuse stop assailants from hacking into their devices and social media to surveil, harass and hurt them.

  • Using AI to Find Anomalies Hiding in Massive Datasets

    Identifying a malfunction in the nation’s power grid can be like trying to find a needle in an enormous haystack. A new machine-learning technique could pinpoint potential power grid failures or cascading traffic bottlenecks in real time.

  • Improving Bay Area Seismic Hazard Maps

    Using the Santa Cruz Mountains as a natural laboratory, researchers have built a 3D tectonic model that clarifies the link between earthquakes and mountain building along the San Andreas fault for the first time. The findings may be used to improve seismic hazard maps of the Bay Area.

  • A Security Technique Fools Would-Be Cyber Attackers

    Multiple programs running on the same computer may not be able to directly access each other’s hidden information, but because they share the same memory hardware, their secrets could be stolen by a malicious program through a “memory timing side-channel attack.” Researchers demonstrate a method that safeguards a computer program’s secret information while enabling faster computation.

  • How AI Is Shaping the Cybersecurity Arms Race

    The average business receives 10,000 alerts every day from the various software tools it uses to monitor for intruders, malware and other threats. Dealing with this avalanche of alerts is achallenge which underscores the need for better ways to stem the tide of cyber-breaches.
