Billion-year-old Mars sand dunes let scientists peek into planet’s windy past

The HiRise camera on the Mars Reconnaissance Orbiter snapped these dune fields in Valles Marineris. They’re estimated to be a billion years old

Mars has a roughly 4.5-billion-year history. Thanks to our robotic explorers, we have a good sense of its current climate and atmosphere. A new study of ancient sand dunes points to what it might have been like a billion years ago on the red planet. 

A team led by Planetary Science Institute (PSI) research scientist Matthew Chojnacki took a close look a wind-driven dune fields in Valles Marineris, an area of Mars known for its extensive canyons. The dunes appear to have been preserved through lithification, a geologic process that turns sediments into rock.

The team published a study on this window into the martian past in the journal

Select PS5 Games Available For $50 Before Launch, In A Roundabout Way

If you want to play 2020’s biggest upcoming games on both your current gaming hardware and the upcoming next-gen consoles, console manufacturers and game publishers are making the transition a bit smoother than usual. Microsoft is unifying its Xbox One and Xbox Series X physical discs by offering one “Xbox” version that is compatible with both platforms, touting how backward-compatible the Series X will be with other Xbox console games. Meanwhile, pre-order listings for PS5 games show two different boxes, one for next-gen and one for PS4, but plenty of PS4 games will have free upgrades to PS5, which will probably be a little confusing for those who are window-shopping at major retailers at launch. The distinction also has the potential to cost you more money if you aren’t careful.

PS5 pre-order listings for a trio of upcoming Ubisoft games–Watch Dogs Legion, Assassin’s Creed Valhalla, and Far Cry 6–are currently

Amazon’s Josh Miele and Anne Toth talk Alexa and the future of accessibility at Sight Tech Global

When Alexa launched six years ago, no one imagined that by today there would be hundreds of millions of Alexa-enabled devices or that Alexa would become part of so many lives. For people who are blind or visually impaired, voice assistants are a huge convenience, whether you are calling a loved one, cooking a meal, checking a sports score, or asking for the weather or time. This fall, Alexa introduced personalization and conversational capabilities that are steps toward a more human-like, digital factotum.

It’s exciting to announce that Amazon’s Josh Miele, Principal Accessibility Researcher at Amazon’s Lab126, and Anne Toth, Director of Amazon’s Alexa Trust, will be speaking at Sight Tech Global, a virtual, global event that addresses how rapid advances in technology, many of them AI-based, will influence the development of accessibility and assistive technology for people who are blind or visually impaired.

House Democrats say Facebook, Amazon, Alphabet, Apple enjoy ‘monopoly power’

A Democratic congressional staff report recommends changes to antitrust laws and enforcement that could result in major changes for Big Tech companies like spinning off or separating parts of their businesses or making it harder to buy smaller companies.

The staff found, after a 16-month investigation into competitive practices at Apple, Amazon, Facebook and Google, that the four businesses enjoy monopoly power that needs to be reined in by Congress and enforcers.

In a nearly 450-page report, the Democratic majority staff laid out their takeaways from hearings, interviews and the 1.3 million documents they scoured throughout the investigation. They conclude that the four Big Tech companies enjoy monopoly power and suggest Congress take up changes to antitrust laws that could result in parts of their businesses being separated.

You can read the full report here.

The recommendations from Democratic staff include:

Multi-trophic aquaculture: A feasible option for the future of aquaculture

EUROPEAN UNION
Wednesday, October 07, 2020, 04:00 (GMT + 9)

A group of European experts has been working for more than three years on the definition of integrated multi-trophic aquaculture and the appropriate framework for its development, the validation of technology and production processes specific to this type of aquaculture, the study of its environmental impact, and the strengthening of collaboration networks between the scientific community, business and government. All of this is done with the aim of putting to good use all the knowledge acquired and making this innovative sustainable aquaculture solution a reality in Europe.

Co-cultivating aquatic species from different trophic levels, such as fish, algae or filter feeders, generates balanced systems that contribute significantly to the environmental and socio-economic efficiency of this industry. This is the objective of Integrated Multi-Trophic Aquaculture (IMTA), a

Previous infection with other types of coronaviruses may lessen severity of COVID-19 — ScienceDaily

Being previously infected with a coronaviruses that cause the “common cold” may decrease the severity of severe acute respiratory syndrome coronavirus (SARS-CoV-2) infections, according to results of a new study. Led by researchers at Boston Medical Center and Boston University School of Medicine, the study also demonstrates that the immunity built up from previous non-SARS-CoV-2 coronavirus infections does not prevent individuals from getting COVID-19. Published in the Journal of Clinical Investigation, the findings provide important insight into the immune response against SARS-CoV-2, which could have significant implications on COVID-19 vaccine development.

The COVID-19 pandemic has led to more than 200,000 deaths in the US, and more than one million globally. There is a growing body of research looking into specific ways that the SARS-CoV-2 virus impacts different populations, including why some people are infected and are asymptomatic, as well as what increases ones mortality as a result of infection.
