European fusion reactor sets record for sustained energy | Science

by

In experiments culminating the 40-year run of the Joint European Torus (JET), the world’s largest fusion reactor, researchers announced today they have smashed the record for producing controlled fusion energy. On 21 December 2021, the U.K.-based JET heated a gas of hydrogen isotopes to 150 million degrees Celsius and held it steady for 5 seconds while … Read more

Fusion Power Experiment in The UK Smashes Its Old Record in Major Step Forward

by

Late last century, the Joint European Torus (JET) near Oxford, UK, churned out 22 megajoules of energy in what was, at the time, a record in fusion power. Now, experimental upgrades have brought the facility into line with the technology anticipated for a major international project, resulting in the production of nearly three times that … Read more

Cyberattack Misinformation Could Be Plan for Ukraine Invasion

by

Last week U.S. officials claimed the Russian government was planning to publish a video of a staged “attack” by Ukrainian forces.

The Emirates Mars Mission, also called Hope, launched in July 2020, arrived at the Red Planet seven months later and successfully entered orbit around Mars on Feb. 9, 2021. After a few months … Read more

Jupiter’s auroras arise from a magnetic ‘tug-of-war’ with volcanic eruptions on its moon Io

by

Jupiter’s auroras are caused by a cosmic game of “tug-of-war,” fueled by volcanoes on the planet’s innermost moon, Io, new research suggests.  NASA’s Juno spacecraft and Hubble Space Telescope have revealed new evidence suggesting Jupiter’s rapid rotation and the release of sulfur and oxygen from volcanoes on Io — the most volcanically active world in … Read more

SpaceX is stacking its giant Starship ahead of Elon Musk’s big update this week

by

SpaceX founder and CEO Elon Musk will have a nice visual aid to point to during his highly anticipated Starship presentation on Thursday (Feb. 10). That talk is an update about Starship, the giant vehicle that SpaceX is developing to take people and cargo to the moon, Mars and beyond. Starship consists of two fully … Read more

Physicists Have Observed a Strange New Kind of Transition in Electronic Crystals

by

As basic science teaches us, changes in temperature can result in phase transitions in materials – like when water solidifies as ice in the freezing cold. However, in some cases the temperature that triggers the change is different depending on whether the material is cooling down or warming up. This is known as a hysteresis … Read more

Mystery Tsunami That Spread Around The World in 2021 Can Finally Be Explained

by

Last year in August, a surprise tsunami in the South Atlantic Ocean mushroomed to distances over 10,000 kilometers (more than 6,000 miles) away, rippling through the North Atlantic, the Pacific, and the Indian Oceans.   It was the first time a tsunami had been recorded in three different oceans since the 2004 Indian Ocean earthquake, … Read more

The First Evidence of Omicron Spilling Over Into Wild Animals Has Just Been Found

by

Vaughn Cooper sees white-tailed deer every day in his neighborhood outside Pittsburgh. The species is common in most US states. Pennsylvania alone has around 1.5 million white-tailed deer – about 30 per square mile (2.6 square km) – while the US has around 30 million in total.   “My dog goes ripping after the deer … Read more
