A new study into the structural damage of two major Antarctic glaciers reveals that ice shelf weakening has rapidly evolved in recent years. Multi-satellite imagery identified damage areas, sparking concerns that structural weakening could lead to major ice shelf collapse in the decades to come. This collapse, in turn, reduces the glaciers’ ability to hold back major sections of the entire West Antarctic Ice Sheet from running into the ocean.


Pine Island Glacier and Thwaites Glacier are located in the Amundsen Sea Embayment. The fastest-changing outlet glaciers in the region, they account for Antarctica’s largest contribution to global sea level rise. Scientists have anticipated for at least 20 years that these glaciers will be the first to respond to climate change, Jessica O’Reilly, an environmental anthropologist at Indiana University, told GlacierHub.

Amazon says 19,000 employees tested positive for COVID-19 as it reveals pandemic data for first time

Amazon released figures on Thursday that for the first time detail the spread of the coronavirus among its employees. The tech giant revealed that more than 19,000 workers have tested positive or been presumed positive for COVID-19.

The company said it has conducted an analysis of data on 1.3 million front-line employees who worked for Amazon and Whole Foods in the U.S. from March 1 to Sept. 19 and compared rates to the general population during that time. Amazon said that if the rate would have been the same among its employees as it is for the general population, it would have seen 33,952 cases among the workforce. Instead, its figure of

First study of its kind reveals the benefits of droplets on leaves — ScienceDaily

Small watery droplets on the edges of blueberry bush leaves are loaded with nutrients for many insects, including bees, wasps and flies, according to a Rutgers-led study, the first of its kind.

The study, published in the journal Proceedings of the Royal Society B: Biological Sciences, suggests that these droplets are an important but underexplored feature in plants, with profound implications for insects in agricultural and natural ecosystems.

“Our study shows for the first time that plant ‘guttation’ — fluid from sap secreted at the edges and tips of leaves — is a nutrient-rich source of food for insects,” said senior author Cesar Rodriguez-Saona, a professor and extension specialist in the Department of Entomology in the School of Environmental and Biological Sciences at Rutgers University-New Brunswick.

Many insects such as bees, wasps and flies drink the small droplets, which arise on nights with high levels of moisture in soil,

Google reveals new 5G Pixel smartphone with cheaper price tag and gaming offering

Gallery: Upcoming phones: The future smartphones of 2020 and 2021 (Pocket-lint)

Google has unveiled its Pixel 5 smartphone – a 5G-compatible flagship device with a more affordable price tag – and an updated Nest smart speaker, alongside new services including Google TV.

Although the Pixel 5 had been announced earlier this year when Google unveiled the low-cost Pixel 4a phone, consumers are now being given their first look at the device and its specs.

The new handset’s stand-out feature isn’t its 6″ screen or 90Hz OLED display, but its significantly reduced price tag – coming in at £599 ($699), well below the £669 ($799) that the last generation Pixel 4 retailed at.

Affordability seems to have been the key factor for Google when developing the new device, with 5G connectivity allowing users to connect to services off

New study reveals how reptiles divided up the spoils in ancient seas — ScienceDaily

While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs.

Now for the first time, researchers at the University of Bristol have modelled the changing ecologies of these great sea dragons.

Mesozoic oceans were unique in hosting diverse groups of fossil reptiles, many of them over 10 metres long.

These toothy monsters fed on a variety of fishes, molluscs, and even on each other. Yet most had disappeared by the end of the Cretaceous, 66 million years ago, when the dinosaurs also died out. There are still some marine crocodiles, snakes and turtles today, but sharks, seals, and whales took over these ecological roles.

In a new study, completed when she was studying for the MSc in Palaeobiology at the University of Bristol’s School of Earth Sciences, Jane Reeves, now

Scientists at the NOAA Northeast Fisheries Science Center have developed an unusually rich picture of who is eating whom off the Northeastern United States. The findings, published recently in Fish and Fisheries, provide a close look at fish feeding habits for 17 fish species, predators, and their prey.


The predators are divided into 48 predator-size categories, and 14 prey species. Fish predators included Atlantic cod, Atlantic herring, haddock, goosefish, pollock, spiny dogfish, winter flounder, and yellowtail founder among others. Prey species included forage fish, squid, zooplankton, shrimp-like crustaceans, shellfish, brittle stars, sand dollars, and sea urchins.

“We have the largest, continuous dataset of fish feeding habits in

New MacBook Pro Leak Reveals Missing Feature

Apple is widely expected to launch two new MacBooks during October. They will be the first hardware available to the public using the new ARM-based processors instead of the current Intel chips. This is part of a planned two-year transition towards Apple using its own silicon over all of the Mac platform.

The laptops are very much on the bleeding edge of technology, but not much is expected to change on the outside – those who are looking for new design ideas and up to date technology outside of the move to ARM are going to have to wait until the back half of 2021.

Swarm Technologies reveals plan to connect devices for $5 per device per month

SAN FRANCISCO – Swarm Technologies, a Silicon Valley startup seeking to connect sensors in a low-cost, global internet-of-things (IoT) network, announced prices for its satellite communications products Sept. 29, including data services starting at $5 per device per month..

Swarm launched its first 12 operational Spacebee satellites in early September aboard an Arianespace Vega rocket. The Mountain View, California, company plans to complete its constellation of 150 hockey-puck-size satellites before the end of 2021, Sara Spangelo, Swarm co-founder and CEO, said in a Sept. 21 blog post.

Swarm Tile, the company’s satellite modem, carries a $119 price tag. Customers are encouraged to embed Swarm Tile, which is built around a single printed circuit board, into devices.

“Now, every person and IoT machine can have affordable access to two-way data services from any point on Earth at all times,” Spangelo said in a Sept. 29 statement. “Swarm’s global network enables customers

chief executive Jack Dorsey is one of bitcoin’s biggest proponents in Silicon Valley.

Dorsey, who earlier this month said bitcoin is “probably the best” native currency of the internet, has previously gone as far as saying bitcoin has the potential to be the world’s sole currency by 2030.

Now, speaking at the virtual Oslo Freedom Forum 2020, Dorsey has said bitcoin and its underlying decentralized blockchain technology are the future of Twitter.
