It will be used to power oil and gas production.

Hywind Tampen, the world’s largest floating wind farm, located off the coast of Norway, has become operational, a company press release said. Of the 11 turbines involved in the project, the first turbine began power production on November 13, with another six scheduled to go online this year.

With the impending doom of climate change and the recent upshoot of fuel prices, countries around the world are looking to switch aggressively to renewable energy. While those in the tropics are looking at solar power, others that can access winds over the seas are looking to build offshore wind farms.

Genetic diversity enables coral species to adapt to threats from climate change, so researchers have designed an aquarium coral “family tree” to help maintain and promote genetic diversity.

There might be room for everyone, or not. At first glance, the connections between the world’s growing population and climate change seem obvious. The more people we have on this planet, the larger their collective impact on the climate.

The global population is projected to reach 8 billion on 15 November 2022, and India is projected to surpass China as the world’s most populous country in 2023, according to World Population Prospects 2022, released today on World Population Day.

“This year’s World Population Day falls during a milestone year, when we anticipate the birth of the Earth’s eight billionth inhabitant. This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” said UN Secretary-General António Guterres. “At the same time, it is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another,” he added.

Microbial life may have resided within the first four kilometers of Mars’s porous crust.

Four billion years ago, the solar system was still young. Almost fully formed, its planets were starting to experience asteroid strikes a little less frequently. Our own planet could have become habitable as long as 3.9 billion years ago, but its primitive biosphere was much different than it is today. Life had not yet invented photosynthesis, which some 500 million years later would become its main source of energy. The primordial microbes — the common ancestors to all current life forms on Earth — in our planet’s oceans, therefore, had to survive on another source of energy.

Some of the oldest life forms in our biosphere were microorganisms known as “hydrogenotrophic methanogens” that particularly benefited from the atmospheric composition of the time. Feeding on the CO₂ (carbon dioxide) and H2 (dihydrogen) that abounded in the atmosphere (with H2 representing between 0.01 and 0.1% of the atmospheric composition, compared to the current approximate of 0.00005%), they harnessed enough energy to colonize the surface of our planet’s oceans.

Aspiring bakers are frequently called upon to adapt award-winning recipes based on differing kitchen setups. Someone might use an eggbeater instead of a stand mixer to make prize-winning chocolate chip cookies, for instance.

Being able to reproduce a recipe in different situations and with varying setups is critical for both talented chefs and computational scientists, the latter of whom are faced with a similar problem of adapting and reproducing their own “recipes” when trying to validate and work with new AI models. These models have applications in scientific fields ranging from climate analysis to brain research.

“When we talk about data, we have a practical understanding of the digital assets we deal with,” said Eliu Huerta, scientist and lead for Translational AI at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. “With an AI model, it’s a little less clear; are we talking about data structured in a smart way, or is it computing, or software, or a mix?”

Early on Thursday morning, Hurricane Nicole made landfall near Vero Beach on Florida’s eastern coast. Because Nicole had a very large eye, nearly 60 miles in diameter, its strongest winds were located well to the north of this landfalling position.

As a result of this, Kennedy Space Center took some of the most intense wind gusts from Nicole late on Wednesday night and Thursday morning. While such winds from a Category 1 hurricane are unlikely to damage facilities, they are of concern because the space agency left its Artemis I mission—consisting of the Space Launch System rocket and Orion spacecraft—exposed on a pad at Launch Complex-39B. The pad is a stone’s throw from the Atlantic Ocean.

How intense were the winds? The National Weather Service hosts data from NASA sensors attached to this launch pad’s three lighting towers on a public website. It can be a little difficult to interpret the readings because there are sensors at altitudes varying from 132 feet to 457 feet. Most of the publicly available data appears to come from an altitude of about 230 feet, however, which would represent the area of the Space Launch System rocket where the core stage is attached to the upper stage. The entire stack reaches a height of about 370 feet above the ground.
