Arago raises $26M to slash AI energy consumption with breakthrough photonic chip
Arago, a deeptech startup pioneering a new class of energy-efficient AI chips powered by light, has raised $26 million in seed funding to accelerate the commercialisation of its photonic processor, codenamed “JEF”. At the core of “JEF” is a proprietary photonic technology that processes data using lasers instead of transistors. By using photons, light particles that generate much less heat than electrons, this chip can deliver the same performance as top GPUs while consuming 10× less …

Trump sent the National Guard to Los Angeles at a time when state and local officials said they had protests there under control.

The move reflects an increasingly evident pattern of his presidency:
Trump declares an emergency or crisis where many others do not see one,
enabling him to take sweeping actions,
rally supporters and fight on political terrain he finds favorable.

Trump’s declaration of an economic emergency in April enabled sweeping tariffs.
…

For Trump, seizing emergency powers has become central to governing
President Donald Trump has declared emergencies in various areas. He says strong action is needed; critics say the emergencies don’t exist.

Just 2% of tidal and offshore solar energy could make a dent in carbon dioxide emissions
Harnessing just 2% of the energy potential from tidal and offshore solar sources could make a significant dent in global CO2 emissions, new research has found.

The asylum seeker bashers in Dutch parliament - a 2/3 majority - just voted to end priority status of recognised refugees in allocating housing.
The govt organization responsible for shelter is worried about the consequences. Keeping refugees in emergency locations for years will cost billions.

Nach verschlafener Energiewende wollen Start-ups für mehr Unabhängigkeit sorgen
Verschiedene Start-ups arbeiten daran, Strom effizienter zu nutzen, neue Energiequellen zu erschließen und zu speichern. Dafür braucht es mehr Investitionen.

The increasing precipitation deficit in (central) the Netherlands, 1961-2024. While precipitation in the growing season (April-September) hardly changed, evaporation rapidly grew. This explains the increase in the deficit (moving average) from around zero in 1961 to on average over 100 mm by 2024.

Ocean currents can generate electricity, and our study shows Africa's seas have some of the strongest
The world's oceans cover more than 70% of Earth's surface. They're filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine renewable energy. Marine energy is much more predictable and reliable than many other forms of renewable energy because unlike the sun and wind, which regularly do not produce electricity, ocean currents never stop moving around the planet. New research has found that the eastern and south-eastern coas…
