Pilbara freshwater ecoregion. The Pilbara freshwater ecoregion is a freshwater ecoregion in Australia. It includes several river basins in semi-arid northwestern Western Australia.

Geography
The ecoregion includes, from south to north, the drainages of the Greenough, Murchison, Gascoyne, Ashburton, Fortescue, and De Grey rivers. These rivers drain Western Australia's Pilbara and Gascoyne regions.

The climate of the ecoregion is tropical and semi-arid. Most of the rivers are intermittent (or ephemeral). The ecoregion has rugged terrain, underlain by ancient Precambrian blocks. Most of the ecoregion is over 200 metres in elevation, and the highest elevation is Mount Meharry at 1,253 metres elevation. Many of the rivers have carved deep canyons as they drain towards the Indian Ocean. During extended dry periods the rivers are reduced to shallow pools in protected canyons.

The ecoregion adjoins the Great Sandy Desert to the north and east. It adjoins Southwestern Australia to the south, which has a more temperate and moist climate, with more year-round rivers.

There are extensive cave systems on the North West Cape, with subterranean brackish water habitats hosting unique aquatic communities.

The ecoregion corresponds to the Indian Ocean drainage division and mostly corresponds to Pilbara–Gascoyne Level 1 drainage basin as defined in Australia's National Catchment Boundaries (NCB) system, although Pilbara–Gascoyne excludes the De Grey River.

Fauna
The fish fauna includes both species widespread through Australia and species endemic to the ecoregion. 20 fish species are native to the ecoregion, of which 5, or 25%, are endemic. Widespread species include the bony bream (Nematalosa erebi), Hyrtl's catfish (Neosilurus hyrtlii), banded grunter (Amniataba percoides), and spangled perch (Leiopotherapon unicolor).

Endemic freshwater species include the Murchison River hardyhead (Craterocephalus cuneiceps) and  golden gudgeon (Hypseleotris aurea), which are found in the rivers from the Gascoyne south, and the Fortescue grunter (Leiopotherapon aheneus), which is found in the Fortescue and Ashburton rivers.

The blind gudgeon (Milyeringa veritas) and blind cave eel (Ophisternon candidum) are endemic to brackish-water caves on the North West Cape.

2021 Leverkusen explosion. An explosion occurred at Chempark, an industrial park for chemical factories in Leverkusen, North Rhine-Westphalia, Germany, on 27 July 2021, at 09:35 local time, sending a pall of smoke over the city. 

The city of Leverkusen stated that the explosion, which caused a fire, occurred in storage tanks for solvents. In a first statement, the Cologne fire department said that the air pollution measurements did not show any kind of abnormality, the smoke had gone down and that they would continue to measure the air for toxins. Later, the environment department of North Rhine-Westphalia (LANUV) announced they were expecting toxic doses of dioxin, PCB and furan or their derivatives in the fallout from the smoke cloud and told residents in large surrounding areas not to eat or touch fruit from their gardens, even not to clean surfaces and objects from the fallout until further notice.

The explosion killed seven people, thirty-one more people were injured. All the casualties were workers at the site.

François Chollet. François Chollet (; born 20 October 1989) is a French software engineer and artificial intelligence researcher formerly Senior Staff Engineer at Google. Chollet is the creator of the Keras deep-learning library, released in 2015. His research focuses on computer vision, the application of machine learning to formal reasoning, abstraction, and how to achieve greater generality in artificial intelligence.

Education and career 
In 2012, Chollet graduated with a Diplôme d'Ingénieur (Master of Engineering) from ENSTA Paris, a school of the Polytechnic Institute of Paris.

In 2015, Chollet started working at Google shortly after releasing Keras.

In 2019, he published the Abstraction and Reasoning Corpus for Artificial General Intelligence (ARC-AGI) benchmark, which measures the ability of AI systems to solve novel reasoning problems.

In 2024, Chollet launched ARC Prize, a US$1 million competition to solve the ARC-AGI benchmark. He left Google in November 2024 after more than 9 years with the company.

In early 2025, Chollet announced the expansion of ARC Prize into a full-fledged non-profit foundation, to further the mission of guiding and accelerating research progress towards artificial general intelligence.

Books and publications 
Chollet's research papers in artificial intelligence have been published at major conferences in the field, including the Conference on Computer Vision and Pattern Recognition (CVPR), the Conference on Neural Information Processing Systems (NeurIPS), and the International Conference on Learning Representations (ICLR).

Chollet is the author of Xception: Deep Learning with Depthwise Separable Convolutions, which is among the top ten most cited papers in CVPR proceedings at more than 18,000 citations.

Chollet is the author of the book Deep Learning with Python, which sold over 100,000 copies, and the co-author with Joseph J. Allaire of Deep Learning With R.

Awards 

On December 1, 2021, Chollet won the Global Swiss AI Award for breakthroughs in AI.

In September 2024, Chollet was named by TIME as one of the 100 most influential people in AI.

George Smoot Horsley. George Smoot Horsley (1916 – 1992) was a physicist and pioneer in printed circuitry and semiconductors. He was one of the first four recruits by William Shockley to help develop technologies at Shockley Semiconductor Laboratory.

Early life
Horsley was born in 1916 in Brigham City, Utah to Mormon parents Golden and Mary Horsley. He served in the US Army Air Corps during World War II, originally commissioned a Second Lieutenant in 1942 and assigned to field artillery. He attained the rank of First Lieutenant and earned his Aviator Badge to become a pilot in October 1943. He had served as a missionary and in 1945 was named an acting Chaplain aboard a ship bound for North Africa. He served in Africa and Italy. In 1945, near the close of the war, he began taking a course in Algebra with the Armed Forces Institute.

After his military service had ended, he enrolled at the University of Utah, where his grades were sufficient to admit him into Phi Beta Kappa. He obtained his PhD in physics from University of Utah in 1954.

Career
During the winter of 1954–1955, William Shockley decided to seek a sponsor to help him establish production of complex transistors and his own Shockley diodes. He was initially supported by Raytheon, but the agreement was soon canceled by that company. After Shockley subsequently established Shockley Semiconductor Laboratory under the umbrella of Beckman Instruments, he recruited four men: William W. Happ who he knew from Raytheon, Horsley and Leopoldo B. Valdes both of whom he knew from Bell Labs, and Richard Victor Jones, a new Berkeley graduate. Horsley had also previously worked at Motorola.

Horsley's name appears on Shockley patents originally from 1959 but re-dated 1964 after Shockley Labs had been sold to Clevite.

Cicaré CH-8. The Cicaré CH-8 is a series of ultralight, kit-built helicopters based on a single-seat Argentinian design from the late 1980s. It was later developed into a tandem two-seater, and later into a side by side ULM and remains in production.

Design and development

The piston engine-powered CH-8 ultralight series use the traditional "penny-farthing" layout with two-bladed main and tail rotors.  The main rotor is formed from composites and is a teetering, semi-rigid design with 6° of twist.  The pod-and-boom fuselage has a carbon fiber and epoxy resin cabin  with a long transparent forward-opening canopy. This large windshield allows the pilot to see the tip of the skid making easier to get a ground reference while landing.
The frame is built on aeronautical SAE 4130 chrome molybdenum steel tube  and welded in spatial reticulated configuration.
The steel frame also carries the engine, semi-exposed behind the accommodation and connected to the main rotor shaft by a belt drive.  A slender aluminium boom, strengthened by a pair of long struts to the lower fuselage frame, carries both the tail rotor and swept fins.  The upper fin is topped with a short horizontal T-shaped tailplate, with small endplate fins, and the lower one ends with a tailskid.

Operational history
100 Helis were built between 2014 and 2021.
