How a bamboo-inspired design helps detect dangerous helium escapes

Helium may seem harmless-it’s the gas that makes balloons float and voices squeak-but in enclosed spaces, a helium leak can be dangerous. Because helium is colorless, odorless, and chemically inert, it is extremely difficult to detect. Worse, if too much helium builds up indoors, it can push out oxygen, creating a serious risk of suffocation.

The Complexity of Civet Coffee Goes Well Beyond Your Palate

The post The Complexity of Civet Coffee Goes Well Beyond Your Palate appeared com. Civet coffee is highly prized for its unique flavor and rarity, but consumption comes with ethical questions. Wildlife smuggling routes exist all throughout Asia as do criminal smuggling enterprises generally. Profiteers want to make money however they can, so the same routes that move narcotics and scam center workers are used to trade in helpless animals like civets. A civet coffee habit supports this interconnected network. Exploitation and misery give civet coffee its unique flavor. Wildlife Alliance Misery at Every Level Sustainability isn’t a concept in the civet coffee industry. For wild civet coffee, the scavenging of civet droppings disrupts natural seed dispersal patterns. Wild civet coffee comes from collected droppings and in theory this doesn’t hurt the animal at all, but the broader ecological disruption should be investigated as researchers recommend. For farmed civet coffee, every part of the animal’s experience is misery. There’s a direct link between your civet coffee preference and the ills of poaching in Southeast Asia. Specially crafted snares will catch an unsuspecting civet and if it survives the snare, it will be bundled away by the smuggler who transports it abroad. The Civet Snare. Wildlife Alliance If the civet doesn’t survive the trap, then it can be eaten. Bushmeat in its various forms is common in this part of the world. Our team observed an increase in overall demand, and in the price gap between live and dead civets around 2014, and this was driven by civet coffee farms in neighboring nations. Bushmeat prices didn’t change but the price of live civets distinctly increased. Civets rescued from a smuggler. From the moment of capture, these animals are kept in torturous conditions. Wildlife Alliance Civet farms in Vietnam claim the animals they use are bred in captivity, but we know firsthand that civet smuggling in.

DeFi Turns Toward Transparency Amid Market Turmoil

The post DeFi Turns Toward Transparency Amid Market Turmoil appeared com. Balancer suffered one of the largest decentralized finance (DeFi) exploits on Monday, with more than $116 million in staked Ether and liquidity pool tokens drained from Balancer v2 contracts and several forks. The decentralized exchange (DEX) and automated market maker (AMM) investigated what appeared to be faulty access control in its smart contracts, which allowed the attackers to withdraw funds directly from liquidity pools. The exploit began with a $70 million loss, which ballooned to $116 million, primarily affecting liquid staking assets such as Lido’s wstETH and StakeWise’s osETH. In a bid to recover losses, Balancer offered a 20% white hat bounty to the attackers. The team warned that it’s working with law enforcement and blockchain forensics to identify the culprit. On Tuesday, Balancer came under scrutiny as community members pointed out the extensive audits it had undergone, only to still be hacked in the end. “Balancer went through 10+ audits,” said Suhail Kakar, a developer relations lead at the TAC blockchain. The hack also showed signs of months-long planning by a skilled attacker. Conor Grogan, director at Coinbase, said the hacker appeared to be experienced and had funds potentially linked to previous exploits. On Thursday, Balancer released a preliminary post-mortem report after the $116 million hack. The protocol said it was hit by a sophisticated code exploit that targeted its v2 Stable Pools and Composable Stable v5 pools. The event triggered stablecoin depeggings and liquidity freezes across the ecosystem due to associated assets. DeFi analysts said the protocol’s collapse had a ripple effect throughout DeFi, with millions.
