Interest in Geothermal Energy is Growing
These days, some 400 power plants in 30 countries generate electricity using steam generated beneath the earth’s surface, producing a total capacity of 16 gigawatts (GW). Despite its advantages, geothermal energy has seen limited use compared to fossil fuels, but recent energy shocks have increased interest in this energy source.

Calls for More Progress on Space Governance Growing Louder
Space may seem infinite, but the narrow band that hugs the Earth, where satellites and space stations operate, is not. A recent RAND study described it as congested, contested, and littered with debris. Tens of thousands of additional satellites are scheduled to launch in the next few years, the vanguard of a new space era. Existing space treaties won’t be enough to keep them safe, to prevent crowding and collisions, and to preserve the promise of outer space.

Towers in the Storm
The problem with the U.S. electrical grid is that many transmission towers have exceeded their design life by about 50 years, which means the aging grid today faces bigger chances of failure. One threat to the grid is from damaging winds of extreme storms such as hurricanes.

Pathogen Early Warning
When COVID-19 struck in late 2019 and early 2020, governments worldwide were caught off guard. The systems that countries and international institutions established, particularly those designed to spot novel threats before they metastasized into something more dangerous, proved insufficient to halt COVID-19’s spread. Since then, the importance of effective early warning systems has only increased.

Successful Sounding Rocket Campaign Advances Hypersonic Weapon Tech for Navy, Army
Hypersonic weapons are weapons travelling at hypersonic speed – at between 5 and 25 times the speed of sound, about 1 to 5 miles per second (1.6 to 8.0 km/s). Sandia Lab’s researchers use a new vehicle which imitates boost-glide trajectory for over a minute.

Flameproofing Lithium-Ion Batteries with Salt
Rechargeable lithium-ion batteries power phones, laptops, other personal electronics and electric cars, and are even used to store energy generated by solar panels. But if the temperature of these batteries rises too high, they stop working and can catch fire. A polymer-based electrolyte makes for batteries that keep working – and don’t catch fire – when heated to over 140 degrees F.
