Worsening wildfires are causing unprecedented devastation worldwide, leaving communities to grapple with loss and the urgent need for solutions. Survivors of record-breaking fires in California and Hawaii highlight the deadly risk of flames and smoke. As these infernos age, responders harness new and old technologies to mitigate threats. Cutting-edge science is critical to understanding these complex events and safeguarding our communities. From the ashes, pioneers emerge to rebuild and adapt.

A warmer planet is creating drier conditions and increasing lightening activity – this means more fuel AND ignition – causing catastrophic wildfires and other anomalies like firenadoes. The trend is showing more megafires and a longer fire season, in some cases making wildfires a year-round concern. Large wildfires are also burning in unusual places such as the Arctic Circle. This episode follows recent megastorm events in California and Alberta, Canada

Climate change means warmer ocean temperatures and higher sea levels. This, in turn, is intensifying and strengthening hurricanes and tropical cyclones. Some experts believe it’s time to add a category 6 to the Saffir-Simpson hurricane wind scale. This episode follows the recent Mexico Beach, Florida and Houston, Texas hurricanes.

Anti-gravity is one of those controversial subjects that some say is more in the realm of science fiction than science fact with many physicists saying it’s just not theoretically possible while others are busy trying to find theories that would allow it to be possible.
In this video, we look at some of the things that we thought were anti-gravity but turned out not to be and what could be our nearest discovery with the vailidation of Einstein’s predictions of space and gravity warping.

Written, researched and presented by Paul Shillito.

30 апреля в 21:00 мск с 45-й площадки Байконура состоялся пуск новой российской ракеты-носителя среднего класса «Союз-5».

«Союз-5» — ракета-носитель с самым мощным в мире жидкостным ракетным двигателем.

Это первый старт ракеты нового поколения в рамках лётно-конструкторских испытаний.

Первая и вторая ступени «Союза-5» отработали штатно, габаритно-массовый макет выведен на расчётную суборбитальную траекторию с последующим падением в заранее закрытом для судоходства и авиации районе в акватории Тихого океана.

Astronomy has always progressed alongside breakthroughs that bypass the limits of human eyesight. Now, through infrared light and gamma radiation, we can peer deeper into the universe than ever before.

High in the mountains, far from the light pollution of big cities, Chile’s Atacama Desert provides spectacular views of the night sky. Gaze upon a spectacle that rivals, and sometimes surpasses, images produced by the Hubble Space Telescope.
