CoolMitt Blood Cooling Device Bring Cooling Technology to Paris Games

Craig Heller of Stanford University is an expert in body temperature regulation. Heller told the Reuters news agency, "It can be very hot and miserable (in Paris), as it was in Tokyo during the last Olympics...And that increase in environmental temperature has lots of effects on performance."

Heller co-invented CoolMitt, a device worn like a glove on the hand. The device helps take out heat while cooling the blood. The cooled blood is sent back to the heart and to the athlete's muscles.

Surveillance technology and spyware are being used to target and suppress journalists, dissidents, and human rights advocates everywhere.

Surveillance Watch is an interactive map that documents the hidden connections within the opaque surveillance industry. Founded by privacy advocates, most of whom were personally harmed by surveillance tech, our mission is to shed light on the companies profiting from this exploitation with significant risk to our lives.

By mapping out the intricate web of surveillance companies, their subsidiaries, partners, and financial backers, we hope to expose the enablers fueling this industry's extensive rights violations, ensuring they cannot evade accountability for being complicit in this abuse.

Surveillance Watch is a community-driven initiative, and we rely on submissions from individuals passionate about protecting privacy and human rights. Acknowledging that we are barely scratching the surface of this industry, our interactive map is just the beginning – we are continuously working to expand this resource to include other information and integrate with existing databases that track this data.
NASA Launches New Satellite to Study Oceans, Atmosphere

The American space agency NASA has launched a new satellite designed to closely study the world’s oceans and atmosphere.

NASA launched the PACE satellite on February 8. A SpaceX Falcon 9 rocket carried PACE into orbit from Kennedy Space Center in Florida. NASA confirmed the launch and reported ground controllers had successfully established contact with the satellite.

PACE stands for Plankton, Aerosol, Cloud, Ocean Ecosystem. The satellite will spend at least three years studying the environment from an orbit 676 kilometers above the Earth’s surface. NASA officials say PACE will map the entire world each day with two science instruments. A third instrument will collect monthly measurements. Scientists should start getting their first data within one or two months.

Jeremy Werdell is the Project Scientist for the PACE project, or mission. He told The Associated Press he sees the effort providing humans “an unprecedented view of our home planet."

Werdell noted a major goal of the observations is to help scientists improve their ability to predict hurricanes and other severe weather events. He said the instruments can provide detailed data on temperature-related changes happening across the world. The satellite data might help scientists better predict when harmful algae blooms will happen.

NASA says PACE will also study aerosols, or particles in the air. Karen St. Germain is NASA’s director of Earth science. She told reporters before PACE’s launch that the study of aerosols is important because they can affect clouds. Aerosols can affect the density of clouds, as well as when and how much precipitation the clouds might release.

St. Germain noted existing satellites are not equipped to collect detailed data on aerosols. She said PACE will help NASA learn more about how aerosols affect clouds and climate over long periods. The new data is expected to give scientists “another dimension” of data on how aerosols affect oceans and the atmosphere.

St. Germain added, “And then, of course, there is a relationship between the phytoplankton and the aerosols.” Phytoplankton are very small plants that float near the surface of water. They serve as a source of food for many sea creatures. NASA says phytoplankton “provide food to all sorts of animals ranging from shellfish to finfish to whales.”

NASA says PACE’s instruments will aim to measure changes in phytoplankton. The satellite will aim to collect data on aerosols that attach to phytoplankton. These studies will be important in identifying any changes in phytoplankton from interactions with aerosols which could affect the ocean and life in it.

NASA has already launched a series of Earth-observing satellites and instruments into orbit. But the agency believes PACE will be able to collect more detailed data on how different aerosols and pollutants get into the oceans and the atmosphere.

Project Scientist Werdell noted that current Earth-observing satellites can only see in seven or eight different colors. But he said Pace will see in 200 colors, permitting scientists to better identify different kinds of algae in the sea and particles in the air.

News reports say the mission will cost about $950 million.

The PACE mission follows the launch in December 2022 of NASA’s SWOT satellite. The SWOT mission measures sea levels and changes in bodies of water over time. SWOT is a cooperative effort between NASA and France’s space agency.

NASA is cooperating with India on another Earth-observing satellite set to launch this year. That spacecraft, called NISAR, will use radar instruments to measure the effects of rising temperatures on glaciers and other melting, icy surfaces.

Wi-Fi Goes Long Range on New WiLo Approach

The new technique could underpin agricultural sensor networks and smart cities

Researchers have developed a hybrid technology that would combine Wi-Fi with the Long Range (LoRa) networking protocol, yielding a new long-distance wireless concept called WiLo. The research team has designed their proposed WiLo tech to be used on existing Wi-Fi and LoRa hardware.

The advance may find applications in Internet of Things (IoT) technologies–such as networks of long-range sensors used in agriculture or smart cities.

Demin Gao, a professor in the College of Information Science and Technology at Nanjing Forestry University in China, notes that Wi-Fi has limitations today in its range and its high power consumption. By contrast, LoRa is based on low power requirements that yield long-range communication capabilities and is often used for IoT applications.

In WiLo, the two communications protocols have been combined to maximize advantages of each one, without the need for additional tech to bridge the two systems. “This reduces costs, complexity, and potential points of failure, making IoT deployments more efficient and scalable,” Gao says.

The researchers—hailing from universities in Hong Kong, mainland China, South Korea, the United States, and the United Kingdom, as well as Intel employees in Germany—conducted their WiLo experiments using an off-the-shelf SX1280 LoRa transceiver produced by Semtech. And while the SX1280’s 2.4 GHz communications band is shared with Wi-Fi (and a host of other standards and technologies), Wi-Fi and LoRa signals are not compatible.

So the researchers developed an algorithm to manipulate the frequency of Wi-Fi’s data transmission signals to match the signals that the LoRa device uses to communicate with other devices. In technical terms, they manipulated Wi-Fi’s data multiplexing standard (called OFDM) to emulate the longer-ranged chirp signals used in LoRa’s chirp-spreading standard (called CSS).

“This enables the use of standard Wi-Fi devices to communicate over long distances using LoRa without additional hardware,” says Gao.

The team tested their new WiLo approach both indoors—in a lab and hallway—and outdoors, over distances up to 500 meters. The researchers reported WiLo achieved a 96 percent successful transmission rate.

Gao says one benefit of WiLo concerns its ability to run on existing, off-the-shelf hardware. As a result, it would not require substantial deployment costs or complexity. On the other hand, one of WiLo’s limitations is the additional power consumption required for Wi-Fi devices to simultaneously handle communication and signal emulation—a problem Gao and his colleagues aim to address in future work.

Moving forward, Gao says, “To commercialize WiLo, the next steps would involve further optimization of the system to improve energy efficiency, data rates, and robustness against interference. This may require additional software development and testing across various IoT environments.”

Ensuring that the system complies with industry standards and integrating security measures for cross-technology communication are also necessary steps, Gao adds.

The team published their research last month in the journal IEEE Transactions on Communications.

A major step toward fully 3D-printed active electronics

By fabricating semiconductor-free logic gates, which can be used to perform computation, researchers hope to streamline the manufacture of electronics.

The devices are made from thin, 3D-printed traces of the copper-doped polymer. They contain intersecting conductive regions that enable the researchers to regulate the resistance by controlling the voltage fed into the switch.
