actual journalism. well done, Alan Taylor!
100 years ago, in the summer of 1914, a series of events set off an unprecedented global conflict that ultimately claimed the lives of more than 16M people, dramatically redrew the maps of Europe, and set the stage for the 20th Century.
We present a method that enables users to perform the full range of 3D manipulations, including scaling, rotation, translation, and nonrigid deformations, to an object in a photograph. As 3D manipulations often reveal parts of the object that are hidden in the original photograph, our approach uses publicly available 3D models to guide the completion of the geometry and appearance of the revealed areas of the object. The completion process leverages the structure and symmetry in the stock 3D model to factor out the effects of illumination, and to complete the appearance of the object. We demonstrate our system by producing object manipulations that would be impossible in traditional 2D photo-editing programs, such as turning a car over, making a paper-crane flap its wings, or manipulating airplanes in a historical photograph to change its story.

Each unique Tree of 40 Fruit grows over 40 different types of stone fruit including peaches, plums, apricots, nectarines, cherries, and almonds. Sculpted through the process of grafting, the Tree of 40 Fruit blossom in variegated tones of pink, crimson and white in spring, and in summer bear a multitude of fruit.

Any progress on interesting materials (read: not plastic) is welcome news.
Researchers have developed a 3D printing process that transitions from one metal or alloy to another in a single object. For example, they created a prototype of an improved telescope mirror mount. The part at the top near the glass mirror is made of a metal with low thermal expansion, so that it won’t shrink in space as much as most metals do. That prevents stress in the epoxy adhesive between the mirror and the metal. The bottom part of this mount is stronger stainless steel and could be connected to a stainless steel component of a spacecraft.
2023-04-04: Controlling the cooling is crucial to avoid weaknesses
While the printing process wastes less material and can be used to produce more complicated shapes than traditional manufacturing methods, researchers have struggled to grasp how to steer metal toward particular kinds of crystals over others.
This lack of knowledge has led to parts with complex shapes cracking prematurely thanks to their crystal structure. “Among the 1000s of alloys that are commonly manufactured, only a handful can be made using additive manufacturing”. The data depicted the push and pull between 2 kinds of crystal structures, austenite and delta ferrite, the latter being associated with cracking in printed parts. As cooling rates surpassed 1.5m kelvins per second, austenite began to dominate its rival. This critical threshold lined up with what the model foretold. The model can inform what cooling rates to select for the early solidification steps of the printing process. That way the optimal crystal structure would appear within their desired material, making metal 3D printing less of a roll of the dice.
When the Muslim Brotherhood government fell, the military leaders cracked down. They sentenced 100s of the Brotherhood’s leadership class to death. They also closed 95% of the tunnels that connected Egypt to Gaza, where the Brotherhood’s offshoot, Hamas, had gained power. The Egyptian move was economically devastating to Hamas. Hamas derived 40% of its tax revenue from tariffs on goods that flowed through those tunnels. Hamas needed to end that blockade, but it couldn’t strike Egypt, so it struck Israel. If Hamas could emerge as the heroic fighter in a death match against the Jewish state, if Arab TV screens were filled with dead Palestinian civilians, then public outrage would force Egypt to lift the blockade. Civilian casualties were part of the point. “Make no mistake, Hamas remains committed to the destruction of Israel. But Hamas is firing rockets at Tel Aviv and sending terrorists through tunnels into southern Israel while aiming, in essence, at Cairo.”
