How to hide from a drone – the subtle art of ‘ghosting’ in the age of surveillance

Posted by in categories: drones, security, surveillance

Drones of all sizes are being used by environmental advocates to monitor deforestation, by conservationists to track poachers, and by journalists and activists to document large protests. As a political sociologist who studies social movements and drones, I document a wide range of nonviolent and pro-social drone uses in my new book, “The Good Drone.” I show that these efforts have the potential to democratize surveillance.

But when the Department of Homeland Security redirects large, fixed-wing drones from the U.S.-Mexico border to monitor protests, and when towns experiment with using drones to test people for fevers, it’s time to think about how many eyes are in the sky and how to avoid unwanted aerial surveillance. One way that’s within reach of nearly everyone is learning how to simply disappear from view.

Airbus to build ‘first interplanetary cargo ship’

Posted by in categories: robotics/AI, space

“This is not just twice as difficult as any typical Mars mission; it’s twice squared — when you think about the complexity involved,” said Dr David Parker, the director of human and robotic exploration at the European Space Agency (Esa).

“And this satellite that Airbus will build — I like to call it ‘the first interplanetary cargo ship’, because that’s what it will be doing. It’s designed to carry cargo between Mars and Earth,” he told BBC News.

Dr Parker announced the European aerospace company’s role in the Earth Return Orbiter (ERO) at a NASA-Esa briefing with reporters just ahead of Thursday’s launch of the Perseverance robot.

Bitcoin wallet Ledger’s database hacked for 1 million emails

Posted by in categories: bitcoin, finance, security

Bitcoin hardware wallet maker Ledger revealed today that its e-commerce database was hacked last month, leaking 1 million emails and some personal documents. No user funds were affected by the breach.

Ledger said the attack targeted only its marketing and e-commerce database, meaning the hackers were unable to access users’ recovery phrases or private keys. All financial information—such as payment information, passwords, and funds—was similarly unaffected. The breach was unrelated to Ledger’s hardware wallets or its Ledger Live security product, the company added.

“Solely contact and order details were involved. This is mostly the email address of approximately [1 million] of our customers. Further to the investigation, we have also been able to establish that a subset of them was also exposed: first and last name, postal address phone number, and product(s) ordered,” said Ledger in its announcement.

MIT Dream Research Interacts Directly With an Individual’s Dreaming Brain and Manipulates the Content

Posted by in categories: neuroscience, wearables

Device not only helps record dream reports, but also guides dreams toward particular themes.

The study of dreams has entered the modern era in exciting ways, and researchers from MIT and other institutions have created a community dedicated to advancing the field, lending it legitimacy and expanding further research opportunities.

In a new paper, researchers from the Media Lab’s Fluid Interfaces group introduce a novel method called “Targeted Dream Incubation” (TDI). This protocol, implemented through an app in conjunction with a wearable sleep-tracking sensor device, not only helps record dream reports, but also guides dreams toward particular themes by repeating targeted information at sleep onset, thereby enabling incorporation of this information into dream content. The TDI method and accompanying technology serve as tools for controlled experimentation in dream study, widening avenues for research into how dreams impact emotion, creativity, memory, and beyond.

Coronavirus vaccine hope rises after a flurry of positive results

Posted by in category: biotech/medical

AMID rising global numbers of daily coronavirus infections, a fresh flush of vaccine trial results is offering hope for the longer run.

There are more than 160 coronavirus vaccines in development around the world. About 140 of these are at the preclinical stage, meaning they are still being looked at in laboratories and in animal tests. Another 25 are already being tested in people.

Decline of bees, other pollinators threatens US crop yields

Posted by in categories: biological, evolution, food, habitats

Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date.

Most of the world’s crops depend on honeybees and for , so declines in both managed and wild bee populations raise concerns about , notes the study in the journal Proceedings of the Royal Society B: Biological Sciences.

“We found that many crops are pollination-limited, meaning would be higher if crop flowers received more pollination. We also found that honey bees and wild bees provided similar amounts of pollination overall,” said senior author Rachael Winfree, a professor in the Department of Ecology, Evolution, and Natural Resources in the School of Environmental and Biological Sciences at Rutgers University-New Brunswick. “Managing habitat for and/or stocking more honey bees would boost pollination levels and could increase crop production.”
