After a decade of design and fabrication, General Atomics is ready to ship the first module of the Central Solenoid, the world’s most powerful magnet. It will become a central component of ITER, a machine that replicates the fusion power of the Sun. ITER is being built in southern France by 35 partner countries.

ITER’s mission is to prove energy from hydrogen fusion can be created and controlled on earth. Fusion energy is carbon-free, safe, and economic. The materials to power society with hydrogen fusion for millions of years are readily abundant.

Despite the challenges of Covid-19, ITER is almost 75 percent built. For the past 15 months, massive first-of-a-kind components have begun to arrive in France from three continents. When assembled together, they will make up the ITER Tokamak, a “sun on earth” to demonstrate fusion at industrial scale.

After years of promises and some limited cooperation, Russia and China have begun to draw up ambitious plans for missions that would directly compete with those of the United States and its partners, ushering in a new era of space competition that could be as intense as the first.

The budding new partnership reflects the geopolitics of the world today.

China and Russia have grown increasingly close under their current leaders, Xi Jinping and Vladimir V. Putin, smoothing decades of mistrust between the countries and creating a potent, though unofficial, alliance against what they perceive as the hegemonic behavior of the United States. Space has become a natural extension of the two countries’ warming ties, given increasingly fraught relations with the United States.

Russian officials have already signaled they may pull out of the International Space Station once the current agreement with its partners ends in 2024. The launch last year of SpaceX’s crew capsule had already ended Russia’s exclusive role ferrying American astronauts into orbit.

Southwest Airlines canceled 500 flights, 15% of its schedule, Tuesday as it struggled with connectivity issues, a day after technical problem with a weather data supplier delayed hundreds of flights.

The Federal Aviation Administration briefly issued a nationwide ground stop for Southwest, which prevents its flights from taking off to avoid overwhelming destinations.

More than 1690 Southwest flights were delayed on Tuesday, close to half of the carrier’s schedule, according to flight tracking site FlightAware. The airline said operations were returning to normal by Tuesday afternoon.

A giant star called VVV-WIT-08 exhibited a smooth, eclipse-like drop in brightness to a depth of 97% in 2012; minimum brightness occurred in April 2012 and the total event duration was a few hundred days, according to an analysis of data from the VISTA Variables in the Via Lactea survey (VVV), a project using the British-built VISTA telescope in Chile and operated by ESO.

It may belong to a new class of ‘blinking’ binary system, where a giant star — 100 times larger than the Sun — is eclipsed once every few decades by an as-yet unseen orbital companion.

When exposed to human-made noise, seagrass posidonia reveals permanent severe lesions in their sensory organs that sense gravity, which threatens their survival. This is the main conclusion of a recent study of the Laboratory of Applied Bioacoustics (LAB) of Universitat Politècnica de Catalunya BarcelonaTech (UPC) titled “Seagrass Posidonia is impaired by human-generated noise,” which is published in Nature Communications Biology.

These new findings demonstrate that have the physiological ability to perceive sounds, and just as importantly, reveal that commonly encountered sources of noise in the ocean can contribute to deplete their populations.

The last 100 years have seen the introduction of many sources of artificial noise in the sea environment, which have shown to negatively affect marine organisms. Many aspects of how noise and other forms of energy may critically impact the natural balance of the oceans are still unstudied. A lot of attention has been devoted to determining the sensitivity to noise of fish and marine mammals, especially cetaceans and pinnipeds, because they are known to possess hearing organs. Recent studies conducted at the Laboratory of Applied Bioacoustics (LAB) of the Universitat Politècnica de Catalunya, Barcelona Tech (UPC) have also shown that cephalopods, anemones and jellyfish, while lacking similar auditory receptors, are also affected by artificial sounds. Indeed, marine invertebrates have sensory organs whose main functions allow these species to maintain equilibrium and sense gravity in the water column.
