Tribute to DunkleosteusDunkleosteus was the largest of a group of armoured fish called placoderms. The most notable feature of this fish is cleaver-blade like plates in its mouth for biting through its prey such as other placoderms. It had a bite force in the same league as modern crocodilians and Tyrannosaurus Rex.(contrary to 0:24 and 0:45) There were 9 species in North America, Poland Belgium and Morocco; the biggest and best known D Terrelli being 33 ft long and 8000 pounds. PS this is my first video so please don't be harsh.
Sexual Segregation and Homosexuality in Animal SpeciesEcologists have been studying certain male and female animals that use different habitats depending on their sex. Due to their choice of territory, conservation plans do not usually take into account this preference and, thus, may result in losing many males or females, thereby threatening their populations.
Invasive Vegetation Releases More Carbon, Worsening Global WarmingExotic plant and tree species that are fast-growing are usually planted in efforts ro sequestrate carbon and prevent climate change and global warming. Tree planting has been shown to ameliorate and mitigate the negative consequences of climate change.
Manipulating metals for adaptive camouflageMany species have naturally evolved remarkable strategies to visually adapt to their environments for protection and predation. Researchers have studied adaptive camouflaging in the infrared (IR) spectrum, although the method is highly challenging to develop in the lab. In a new report now published on Science Advances, Mingyang Li and a research team at the National University of Defense Technology in China, developed adaptive thermal camouflage devices that bridged the optical and radiative properties of nanoscopic platinum (Pt) and silver (Ag) electro-deposited Pt films. The metal-based devices maintained large, uniform, and consistent IR tunabilities in the mid-wave IR (MWIR) and long-wave IR (LWIR) atmospheric transmission windows (ATWs). The team multiplexed and enlarged the devices, allowing flexibility for camouflaging capabilities. The technology is advantageous across a variety of camouflage platforms and in many thermal radiation management technologies.

Fight The Power (Full Version) - Public EnemyFight the Power From Wikipedia, the free encyclopedia "Fight the Power" is a 1989 song by hip hop group Public Enemy. First released on the soundtrack for the film Do the Right Thing (Rosie Perez dances to the song over the opening credits), an edited version was released in 1990 on Public Enemy's third album, Fear of a Black Planet. The song has largely served as the political statement of purpose for the group, and is their biggest single. "Fight the Power" was recently ranked #1 on VH1's 100 Greatest Songs of Hip Hop, further demonstrating the impact of the song. The single reached #1 on Hot Rap Singles and #20 on the Hot R&B Singles. Another version is featured in the Chuck D Presents: Louder than a Bomb compilation, featuring a saxophone solo by Branford Marsalis. Brian Hardgroove said, "Law enforcement is necessary. As a species we haven't evolved past needing that. Fight the Power is not about fighting authority—it's not that at all. It's about fighting abuse of power. Music videos Spike Lee produced and directed two music videos for this song. The first featured clips of various scenes from Do the Right Thing. In the second video, Lee used hundreds of extras to simulate a massive political rally in Brooklyn. The extras carry signs featuring Paul Robeson, Marcus Garvey, Chuck Berry and Martin Luther King, Jr. Tawana Brawley made a cameo appearance. Brawley gained national notoriety in 1987 when, at the age of 15, she accused several police officers and public officials from Wappingers Falls, New York of raping her. The charge was rejected in court, and she instead was sued for supposedly fabricating her story. Jermaine Dupri also made a cameo. Samples used The song's title and chorus were inspired by—or taken from—"Fight the Power (Part 1 & 2)," a 1975 protest funk song by The Isley Brothers. "Teddy's Jam" by Guy "Bird of Prey" by Uriah Heep "Hot Pants Road" by The J.B.'s (bassline) "Pump Me Up" by Trouble Funk (percussion, vocal: "Pu-pu-pump") "Different Strokes" by Syl Johnson (heard before the 3rd chorus) "I Shot the Sherriff" by Bob Marley "Planet Rock" by Afrika Bambaataa (Vocal: "Yeah!") "I Know You Got Soul" by Bobby Byrd (Vocal: "I know you got soul") "Sing a Simple Song" by Sly & the Family Stone (Singing heard after the line "Bum rush the show") "Whatcha See Is Whatcha Get" by The Dramatics (guitars) "Let's Dance (Make Your Body Move)" by West St. Mob (Vocal: "Come on you got it") "Funky President" by James Brown (Heard after the line "People, people we are the same") The lyrics also include allusions to James Brown's "Funky Drummer" and "Say It Loud -- I'm Black and I'm Proud," as well as Bobby McFerrin's 1988 hit "Don't Worry, Be Happy." The opening quotation, "Yet our best trained, best educated, best equipped, best prepared troops refuse to fight! Matter of fact, it's safe to say that they would rather switch than fight!," was taken from Chicago attorney and civil rights activist, Thomas "TNT" Todd.12
World Environment Day: Celebrating the UK’s precious biodiversityTo mark World Environment Day, WWF has selected some snapshots of UK nature and wildlife - from land and ocean species to breathtaking plant life - in an attempt to raise awareness of the ongoing fight for our world and its vital biodiversity, the threat to which is both an urgent and existential concern.
