With a Speaker and Four microphones, Drones Can Echolocate Like Bats

Similarly to how bats use echolocation to orient themselves with their surroundings, mathematicians have found that the same can be done with microphones and a speaker on a drone with the help of algebra and geometry. This signal processing research has potential applications for people, underwater vehicles and even cars, said Mireille “Mimi” Boutin, a

Drone Companies Combine Forces to Command the Air, Land and Sea

Drones are commonly known for flying in the sky, but a new breed is rolling around on the ground and swimming in the ocean. Aquiline Drones (AD) will be powering GuardBot’s spherical and amphibious robotic vehicles via the AD Cloud. “Our new alliance with Aquiline Drones now gives us the ability to program our bots

NASA, New Zealand Partner to Collect Climate Data from Commercial Aircraft

NASA is partnering with the New Zealand Ministry of Business, Innovation and Employment, New Zealand Space Agency, Air New Zealand and the University of Auckland to install next-generation Global Navigation Satellite System (GNSS) reflectometry receivers on passenger aircraft to collect environmental science data over New Zealand. The program is part of NASA’s Cyclone Global Navigation

NASA Flights Detect Millions of Arctic Methane Hotspots

The Arctic is one of the fastest warming places on the planet. As temperatures rise, the perpetually frozen layer of soil, called permafrost, begins to thaw, releasing methane and other greenhouse gases into the atmosphere. These methane emissions can accelerate future warming—but to understand to what extent, we need to know how much methane may

Thwaites Glacier Transformed

Antarctica’s Thwaites Glacier has been in the spotlight in recent years, as scientists have undertaken a multi-part international project to study the vast glacier from all angles. The urgency stems from observations and analyses showing that the amount of ice flowing from Thwaites—and contributing to sea-level rise—has doubled in the span of three decades. Scientists

2050 Climate Change City Index

A study revealing how the climate will shift by 2050 in major cities around the globe has been released by apartment rentals platform, ​Nestpick.com​. To understand how some of the most popular cities in the world will be affected by climate change, the apartment platform set out to determine how potential temperature shifts, water shortages

Sea-Level Rise to Cause Major Economic Impact in Absence of Further Climate Action

Rising sea levels, a direct impact of the Earth’s warming climate, is intensifying coastal flooding. The findings of a new study show that the projected negative economy-wide effects of coastal flooding are already significant until 2050, but are then predicted to increase substantially toward the end of the century if no further climate action on

Flooding in Southern Iran

Heavy rainfall has triggered flooding in southern Iran, particularly in the Sistan and Baluchestan, Hormozgan and Kerman provinces. The downpour has led to blocked roads and destroyed bridges, crops and houses, displacing thousands of people. This image, captured by the Copernicus Sentinel-2 mission, shows the extent of the flooding in the Sistan and Baluchestan province

Mapping Soil Moisture In High Definition

Trying to gauge soil moisture across large areas—regions, nations, continents—is difficult, yet knowledge of this dimension of our ecosystem is extremely important for farmers, planners, scientists, insurance companies and anyone concerned about preparing for global environmental change. “Understanding these patterns is critical to national and international security,” said Rodrigo Vargas, associate professor of ecosystem ecology

Greenland’s Rapid Melt Will Mean More Flooding

The Greenland Ice Sheet is rapidly melting, having lost 3.8 trillion tons of ice between 1992 and 2018, a new study from NASA and the European Space Agency (ESA) finds. The study combined 26 independent satellite datasets to track global warming’s effect on Greenland, one of the largest ice sheets on Earth, and the ice
