Everyone knows droughts are bad. They increase risk of wildfires and damage life in the affected region. They are not always predictable, when I lived in Pennsylvania in the early 1990s there was a drought with no known mechanism involved, but they are often cyclical, which makes them at least broadly predictable.

The Dry 2 Dry program at Ghent University believes droughts are not only predictable and cyclical, they can propagate in a kind of feedback loop; instead of being local, evaporated water is moved to other areas, so less of it is taking drought with them.
The "Learning to Discover" workshops and "AI and Physics" conference are taking place at Institut Pascal, a centre set on the top of a hill surrounded by woods near Orsay, France. The event focuses on new artificial intelligence techniques to improve the discovery potential of fundamental science experiments.
Below you can see a summary of the event agenda

- Apr 19-20 Representation learning workshop
- Apr 21-22 Dealing with uncertainties workshop
- Apr 25-26 Generative models workshop

- Apr 27-29 AI and Physics Conference
The world’s largest particle accelerator is back in business. Today, two beams of protons circulated in opposite directions around the Large Hadron Collider’s 27-kilometer ring at their injection energy of 450 billion electronvolts (450 GeV), marking the conclusion of a three year hiatus for maintenance, consolidation and upgrade work.

The work was done so that it can operate at an even higher energy and deliver significantly more data to the upgraded LHC experiments but high-energy collisions still months away. The beams circulated today were a test at injection energy and contained a small number of protons.
The last time the Russians went to war in Europe, it was the Cold War.  After World War II ended, the USSR wanted Germany to remain relatively weak. The US instead believed that part of the reason behind World War II was a Germany that had been too heavily penalized by other European countries after World War I. 

After defeat, Germany had been divided into four sectors, controlled by America, Britain, France, and the Soviet Union and three of those sectors 'united' so that there could be a common currency, a new German mark, and goods supplied by the US under the Marshall Plan would bring stability. But the former capital, Berlin, was in the USSR sector, and the USSR wanted its section of Germany to be Soviet, and communism. 
A new report says that the alternative meat industry, plant-based products designed to look and taste like meat, raised $8 billion even during the pandemic. That's a big success.

They want more but oddly lament that most of their money comes from the private sector. They want the trillions of dollars in subsidies that solar and wind have gotten, claiming it will fight climate change. That's a big problem.

Many are the sci-fi encounters with races that have transcended their physical bodies, having moved on to dwell on some energetic or spiritual plane. The tales skip the backstories, so we wonder: Did these aliens get where they are via Darwinian evolution? Did they get disgusted with the physical world and devise a technological means of transitioning? Do their planets of origin still exist, or were they destroyed? Always in sci-fi, we are given to assume that these aliens enjoy their non-material existence and don’t miss the meat world.

During the almost two years of on-again off-again COVID lockdowns, we heard lots of concern from many different corners about the mental health effects of forcing people to stay home and keep away from friends and family.

Many research projects were undertaken to attempt to measure the scale of the impacts on mental health.

However, the speed with which research was generated meant in some cases, research quality was sacrificed, and some research found evidence of an effect on mental health, and some didn’t.

To make sense of the very mixed findings, my colleagues and I conducted a review of all of the studies on mental health conducted during the first year of the pandemic.

 Solar power has potential but a crippling weakness that has meant despite trillions of dollars in subsidies and continuing mandates, it has not made a dent in use of conventional energy; it is not on demand and batteries are expensive and going to do more harm to the future than natural gas.

The solar energy system MOST – Molecular Solar Thermal Energy Storage Systems - is starting small but the concept of a specially designed molecule that changes shape when it comes into contact with sunlight scaled to operational sizes might mean real solar farms in remote places that provide electricity as well as conventional energy.
Water has varied in temperature for as long as water has existed and it seems evolution has provided coral reefs a recovery mechanism after variation results in 'bleaching' - when corals expel algae and turn white. It can have some impact beyond algae because about 275 million people live near a coral reef and they can be tourist attractions and help support fishing industries.

In 2018, two years after the government protected Chagos Archipelago underwent bleaching, the reef coral cover and carbonate production were down by more than 70 percent. Yet by last year, they were found to have rebounded nicely. 
South-East Asia is a substantial consumer of rice but also accounts for about 40 percent of international rice exports. Before population plateaus some time after 2050, and as globalization makes the world more prosperous, there will likely be 18 percent higher demand for rice in the region.
