An ambitious mission to a very special landing site: our Perseverance rover is heading to the Red Planet to search for signs of ancient life, collect samples for future return to Earth, and help pave the way for human exploration. http://go.nasa.gov/3f6Pd1o

Summary: New artificial intelligence technology can accurately predict how any chemical is going to smell to humans.

A pair of researchers at the University of California, Riverside, has used machine learning to understand what a chemical smells like — a research breakthrough with potential applications in the food flavor and fragrance industries.
What do the loopy straws that children like to sip drinks through have in common with cutting-edge science? Ask Ryan Murphy and his colleagues at the National Institute of Standards and Technology (NIST), where the team has thought up a creative way to explore the properties of fluids under extreme conditions.
The team invented a device that can push fluids through a narrow tube at the velocity of a car hurtling down a rural interstate — about 110 km per hour. This might not sound overly fast to a road tripper, but the tube’s inner diameter is typically 100 micrometers — about the thickness of a human hair. Scaled up, that would be like a train hurtling through a subway tunnel about 100 times faster than a rocket blasting its way into orbit.
To add to the fun, the meter-long tube is coiled up like a spring, so the fluid careens around loop after three-centimeter-wide loop, as though that rocketing subway were a blindingly fast roller coaster that turns somersaults from start to finish.
Summary: First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population.

Two studies led by Stony Brook University researchers to be presented virtually at the Alzheimer’s Association International Conference on July 28, 2020, indicate that World Trade Center (WTC) first responders are at risk for developing dementia. The studies included individuals with signs of cognitive impairment (CI) who show neuroradiological abnormalities and changes in their blood similar to that seen in Alzheimer’s disease patients and those with related dementias.
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.
“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 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.
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.
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.
