Hostages Return Home

Hamas released the last 20 living Israeli hostages yesterday under a ceasefire deal that paused more than two years of war in Gaza, sparked by the militant group's Oct. 7, 2023, attack in southern Israel. Israel then freed nearly 2,000 Palestinian prisoners and detainees. See the surviving hostages here and photos from yesterday here

The exchange is part of a US-backed 20-point peace plan that also includes returning the bodies of 28 dead hostages. Hamas released four bodies yesterday. The group says it does not know the location of some bodies; an international task force will be set up to help locate them. Israeli troops have partially withdrawn from Gaza as aid flows back into the territory and hundreds of thousands of displaced Palestinians return to devastated neighborhoods (see drone footage).

In related news, President Donald Trump visited Israel yesterday to address its legislature—the Knesset—and later joined a summit in Egypt with regional leaders to discuss Gaza's future. 

 

(Another) OpenAI Megadeal

OpenAI and tech giant Broadcom announced a multiyear deal yesterday to develop custom-built chips and infrastructure to expand OpenAI’s compute capacity. The agreement aims to deploy 10 gigawatts of specialized infrastructure by 2029, a total roughly equal to the power consumption of 8 million households.   

It marks the latest megadeal for OpenAI, following hardware and computing agreements with Oracle, Nvidia, AMD, and others. The Broadcom deal will focus on networks of AI accelerators—highly efficient processors that can handle multiple tasks in parallel, performing billions of operations (see 101). The company did not disclose how it was financing the deal; Broadcom’s shares closed up nearly 10% on the news.

OpenAI’s recent deal with Nvidia came after the latter agreed to invest as much as $100B into OpenAI, while part of its deal with AMD will make OpenAI one of AMD’s largest shareholders. See a visualization of the complex web of relationships here.

 

Coral Reef Tipping Point

Coral reefs are the first ecosystem to have passed a climate tipping point, scientists and conservationists contend in a new report. Barring a reversal in warming trends, researchers warn that a large number of coral reefs will be lost in the coming years.

The designation in this case refers to a level of warming at which irreversible damage occurs. Researchers from the UK-led Global Tipping Points organization say the majority of warm-water coral reefs are on track for widespread dieback, after 80% experienced severe bleaching events (see explanation). The report’s authors—160 scientists spanning 23 countries—point to global temperatures regularly exceeding 1.5 degrees Celsius above preindustrial levels, with Earth expected to formally pass that threshold in five years. 

Warm-water reefs cover about 0.2% of the ocean floor but support around one-quarter of marine life. The report’s publication comes roughly one month before Brazil is scheduled to host COP30, the global climate summit. Read the report here.

Should You Be Taking Daily Collagen?

 

Unless you’re a teenager or you’ve found the Fountain of Youth, the answer is: Yes, you should take collagen. As we age, our ability to produce this vital nutrient decreases, leading to joint pain, wrinkles, and other classic signs of aging. *Sigh*

 

But with a daily collagen supplement, you can help restore your collagen levels easily. NativePath’s pure, grass-fed bovine collagen is one of the cleanest, most affordable options available–just add 2 scoops to coffee or water daily for 18g of protein. It supports your cartilage, joint, skin, gut, and nail health. Seriously: One study showed postmenopausal women who took just 5g of collagen daily saw a 7% increase in bone density in one year. 

 

What are you waiting for? 1440 readers can get free collagen with every purchase during their sale!
