Amazon Sidewalk could raise your Wifi bill cybersecurity, expert says

Posted by in categories: cybercrime/malcode, habitats, internet

LYNCHBURG, Va (WSET) — Strangers may soon be able to use your Wi-Fi — It’s all through Amazon Sidewalk.

It’s an internet-sharing network for Amazon Echo, Ring and Tile devices. Officials say it’s a way to use WiFi from neighboring homes that also have Amazon products.

Randy Marchany a cybersecurity expert with Virginia Tech feels this is another way to collect information. He says it’s specifically picking up on user habits and whereabouts.

Building a Garden that Cares for Itself

Posted by in categories: food, habitats, health, robotics/AI

Designing an autonomous, learning smart garden.

In the first episode of Build Out, Colt and Reto — tasked with designing the architecture for a “Smart Garden” — supplied two very different concepts, that nevertheless featured many overlapping elements. Take a look at the video to see what they came up with, then continue reading to see how you can learn from their explorations to build your very own Smart Garden.

Both solutions aim to optimize plant care using sensors, weather forecasts, and machine learning. Watering and fertilizing routines for the plants are updated regularly to guarantee the best growth, health, and fruit yield possible.

Heres What 6G Will Be, According to the Creator of Massive MIMO

Posted by in categories: biotech/medical, habitats, internet, robotics/AI

COVID 19 pandemic, automation and 6G could end the metropolitan era from building high sky scrapers for companies. Companies can operate like a network from home to home without going to office. This will help a lot to bring down Urban Heat Islands and make our cities more efficient in transportation and communication to send the data even faster.

Tom Marzetta is the director of NYU Wireless, New York University’s research center for cutting-edge wireless technologies. Prior to joining NYU Wireless, Marzetta was at Nokia Bell Labs, where he developed massive MIMO. Massive MIMO (short for “multiple-input multiple-output”) allows engineers to pack dozens of small antennas into a single array. The high number of antennas means more signals can be sent and received at once, dramatically boosting a single cell tower’s efficiency.

Massive MIMO is becoming an integral part of 5G, as is an independent development that came out of NYU Wireless by the center’s founding director Ted Rappaport: Millimeter waves. And now the professors and students at NYU Wireless are already looking ahead to 6G and beyond.

Research: Spiders feast on 400–800 million tons of insects every year

Posted by in categories: food, habitats

The next time you see a spider crawling around your house, look at the bright side. It’s probably feasting on a bunch of other insects and providing you with free pest control.

A new study released on Tuesday says that spiders eat an estimated 400 to 800 million metric tons of insects every year.

For comparison, the entire human population consumes about 400 million tons of meat and fish every year.

The next pandemic: Rift Valley fever?

Posted by in categories: biotech/medical, climatology, habitats, health, sustainability

Rift Valley fever used to mostly affect livestock in Africa. But the virus that causes it is also spread by mosquitoes whose habitats are expanding because of climate change. If it were to make its way to the rest of the world, it would decimate livestock causing agricultural collapse as well as affecting human health.

In 2015 the Zika virus triggered a global health crisis that left thousands of parents devastated. The virus can cause serious problems in pregnancy, leading to babies with birth defects called microcephaly and other neurological problems. But Zika is not the only virus that can be devastating to pregnant women and their babies; there is another with pandemic potential that could be even more deadly – Rift Valley fever.

The placenta that encases the baby acts as a fortress against many pathogens, but a few can evade its defences. Rift Valley fever is one of them – a 2019 study shows that the virus has the ability to infect a specialised layer of placental cells that carry nutrients to the baby, something that even Zika may not be capable of. In cattle and other livestock, in which the virus spreads, infection can cause more than 90% of pregnant cows to miscarry or deliver stillborn calves. Although the virus kills fewer than 1% of people it infects, it is the risk to babies, and the lasting neurological effects in adults, that is of great concern.

Run out of milk? Robots on call for Singapore home deliveries

Posted by in categories: habitats, robotics/AI

Got milk?

Hoping to capitalise on a surge in demand for home deliveries, a Singapore technology company has deployed a pair of robots to bring residents their groceries in one part of the city state.

Developed by OTSAW Digital and both named “Camello”, the robots’ services have been offered to 700 households in a one-year trial.
