11 thrilling ways to discover Antarctica
- If you opt for cruising the Antarctic on a larger ship, but prefer true adventure to posh pampering, expedition leader Michael Ginzburg of Oceanwide Expeditions suggests choosing a journey with a flexible itinerary that allows the captain and crew to engage in a little exploration along the way.
- But in recent years, several companies have pioneered day trip and single overnight flights to the continent including DAP Airlines from Punta Arenas in southern Chile and White Desert from Cape Town, South Africa.
- Another throwback to the golden age of polar expedition, sailing across the Drake Passage to the Antarctic offers a quieter, less crowded way to cruise the Southern Ocean, as well as opportunities to explore bays and channels where larger ships can't fit.
Volcano behind huge eruption that kick-started mini ice age identified
- In the middle of the 6th century, a mini ice age that lasted 125 years and an outbreak of plague plunged the world into chaos.
- One of the key events that helped to kick it all off was the massive eruption of a volcano somewhere in the southern hemisphere.
- Now we may know when and where it happened.

Intel unveils its first AI chip Springhill
- The chip, developed at its development facility in Haifa, Israel, is known as Nervana NNP-I or Springhill and is based on a 10 nanometer Ice Lake processor that will allow it to cope with high workloads using minimal amounts of energy, Intel said.
- Facebook, it said, already has started using the product.
- Intel said its first AI product comes after it had invested in Israeli AI startups, including Habana Labs and NeuroBlade.
- It said the new hardware chip will help Intel Xeon processors in large companies as the need for complicated computations in the AI field increases.
ICE says a nurse examined the detained immigrant who claims she is breastfeeding, and she's not lactating
- On Tuesday, Bryan Cox, a spokesman for US Immigration and Customs Enforcement, said immigration officials did not learn of Domingo-Garcia's claim she was breastfeeding an infant daughter until they read it in a news report about a week after she was detained in the raids that yielded the arrests of 680 undocumented immigrants.
- Domingo-Garcia was breastfeeding her daughter to put her to sleep every night, up until she was detained August 7, her attorney, Ray Ybarra Maldonado, told CNN.
- The Rev. Roberto Mena of St. Michael's Catholic Church in Forest, Mississippi, who has been working with the family, told CNN on Tuesday that within the first couple of days of detention, Domingo-Garcia asked authorities to deliver her breast milk to her baby, which they rejected.
Microsoft, Dell, Concur: Here are all the tech companies doing business with ICE and how much they’re getting paid
- Tech companies, which have long emphasized how their products are making the world a better place, make millions from their work with Immigration and Customs Enforcement (ICE), the government organization that’s become infamous for putting children in cages.
- This has manifested in protests that targeted Amazon’s wages and treatment of warehouse workers; sexual discrimination and abuse of employees at companies including Google; and the contracts that companies like Microsoft have with ICE and other government organizations accused of mistreating immigrants.
- ICE contracts with major tech companies like Dell and Microsoft, but also with numerous companies you may never have heard of but that are necessary for the operations of a government body with over 20,000 employees and an $8.8 billion budget.
- Amazon isn’t listed in this dataset, but its highly profitable cloud arm, Amazon Web Services, provides critical support to a number of the other companies on the list, including Palantir, Peter Thiel’s controversial data-mining company.
Supernova dust was found in snow from Antarctica and it could be 20 million years old
- The discovery could provide lessons about the solar system's history and place in its surrounding environment, the study, published August 12 in the Physical Review Letters, said.
- Some of that dust from one or more stars, according to the study, fell to Earth sometime in the last 20 million years.
- They chose to test snow because "it is the purest material you can find," Koll said.
- Researchers were able to determine that the most likely source of the iron-60 found in the Antarctic snow was star dust, Koll said.
- However, it's unclear whether the Earth is currently in a dust cloud or if the discovery is of the remnants of a cloud that passed through years ago, Koll said.
- Koll said the next step is to test deposits from older ice cores to find out when and where the supernova happened and when our solar system entered into the cloud of space dust.
Lawsuit alleges poor medical and mental health care in ICE detention facilities
- Washington (CNN) - The Southern Poverty Law Center and other immigration advocacy groups filed a class action lawsuit Monday alleging a lack of medical and mental health care inside Immigration and Customs Enforcement detention facilities across the United States.
- ICE spokesman Bryan Cox said ICE does not comment on pending litigation, but he said that comprehensive medical care is provided to all individuals in ICE custody.
- Additionally, ICE detainees receive a comprehensive physical exam "within 14 days of arrival to identify medical, mental health and dental conditions that require monitoring or treatment," Cox said.
- The lawsuit, which was filed in federal court in California, covers all current and future ICE detainees and includes about 160 detention facilities.
- The lawsuit seeks to force ICE to take immediate steps to improve conditions and provide adequate staffing.
People in Iceland held a funeral and erected a plaque for a glacier lost to climate change
- Where a glacier once covered nearly 6 square miles of land in Iceland, there is now only a commemorative plaque beside a small patch of snow.
- The glacier, once known as Okjökull ("jökull" means glacier in Icelandic) lost its status as a glacier in 2014, since it had shrunk below one square mile and was barely 50 feet deep, according to The Guardian.
- Rising temperatures due to climate change caused the glacier to melt.
- A heat wave swept Europe and caused extreme ice melt in Greenland that scientists didn't expect to see until 2070 in a worst-case scenario.
- Scientists link this extreme melting to climate change.
- Though glaciers in Iceland have undergone brief periods of expansion, they're shrinking overall due to climate change.
- Iceland loses almost 25 square miles of glacier each year.
The World's Largest Submarine: The Soviet Union's Pr. 941 Typhoon SSBN (2014)
- In this album I refer to the Project 941 SSBNs as Typhoons because if you were to talk to a Russian naval officer or sub designer, they would know exactly what submarine you're talking about.
- The Typhoons have two main pressure hulls in parallel with the missiles between them (the famous gunfight in The Hunt for Red October would in reality have taken place inside a flooded ballast tank).
- Some designers expressed concern about the large "physical fields" produced by such a large submarine, meaning magnetic signature (partially alleviated by the use of titanium) and hydrodynamic signature, a disturbance in the water which the Soviet could detect from space at the end of the Cold War (that's a topic for another time).
At the bottom of a glacier in Greenland, climate scientists find troubling signs
- Greenland lost 12.5 billion tons of ice to melting on August 2, the largest single-day loss in recorded history and another stark reminder of the climate crisis.
- Kulusuk is also base camp for NASA's OMG (Oceans Melting Greenland) program.
- OMG scientists traveled to the world's biggest island this year after a heatwave scorched the United States and Europe, smashing temperature records and triggering the mass melting of its ice sheet.
- NASA took CNN on a dramatic flight over Helheim -- one of the largest glaciers on Greenland and the fastest flowing on the eastern edge of the island.
- Glaciers like Helheim, and even the much smaller ones around villages like Kulusuk, are powerful enough to make the global sea level rise by half a millimeter in just a month -- something NASA researchers say cannot be ignored.
