'We did the best we could': Splendor organizers defend decision after chaotic weekend

Splendor in the Grass co-founder Jess Ducrou said the decision to continue this year’s festival was not motivated by money, and organizers were “doing the best we could” under difficult conditions. Key points: Organizers have defended the decision to continue this year’s festival Jess Ducrou says customers can expect refunds for events canceled on Friday Today’s passengers struggle through the mud to get home Ms Ducrou promised the festival would “definitely” return in 2023 in an interview with Hack on Monday, after a tumultuous weekend in North Byron Parklands. The 2022 edition is dubbed “Splendour in the Mud” because the festival venue was flooded and turned to mud by heavy rains on Thursday night. This creates chaos for people arriving at campsites, who are forced to wait hours to get in or are forced to sleep in their cars. Friday’s main event was later canceled amid fears more rain could destroy the already drenched festival, before the bill went ahead as scheduled on Saturday and

Moths use ultrasound to defend against bats

Using artificial intelligence, researchers have discovered what may be the largest animal mimicry complex on Earth, changing the way we see, or rather hear, the night sky. Credit: Chandan Singh, CC BY 2.0 While a clear night sky may seem calm and peaceful to us, empty of everything but stars, this nocturnal world is filled with a cacophony of high-pitched sounds beyond our ability to hear. Bats penetrate shadows with ultrasonic pulses that allow them to create an auditory map of their surroundings, which is bad news for moths, one of their favorite foods. However, not all moths are defenseless prey. Some emit their own ultrasonic signals that startle the bats to stop the pursuit. Many moths that contain bitter venom avoid capture altogether by producing a different ultrasound that alerts the bat to its foul taste. Others hide themselves in a static sonar-jamming shroud that makes them difficult to locate with bat echolocation. Altho

The immune system uses two-step verification to defend against HIV

Human immunodeficiency virus 1, more commonly known as HIV-1, is known for its remarkable ability to evade the immune system. Scientists at Scripps Research and collaborators have now discovered how our innate immune system – the body’s first line of defense against foreign invaders – detects HIV-1, even when the virus is present in very small amounts. His findings, published on July 8, 2022, in molecular cell , revealing a two-step molecular strategy that jolts the innate immune response into action upon exposure to HIV-1. These discoveries could impact the development of drugs for HIV treatments and vaccines, as well as shape our understanding of how the innate immune response is involved in other areas – including neurodegenerative disorders such as Alzheimer’s. “This study illustrates how the immune system can recognize a very cryptic virus, and then activate a downstream cascade that leads to immunological activation,” said Sumit Chanda, PhD, professor in the Department of Immun
