Manmade mangroves could get to the ‘root’ of the problem for threats to coastal areas

Posted by in categories: computing, engineering, habitats

With threats of sea level rise, storm surge and other natural disasters, researchers from Florida Atlantic University’s College of Engineering and Computer Science are turning to nature to protect humans from nature. They are developing innovative ways to guard coastlines and prevent scouring and erosion from waves and storms using bioinspired materials that mimic mangrove trees found along shores, rivers and estuaries in the tropics and subtropics. Growing from a tangle of roots that twist their way out of the mud, mangrove trees naturally protect shorelines, shelter coastal ecosystem habitats and provide important water filtration. In many cases, these roots trap sediments flowing down rivers and off the land, helping to stabilize the coastline.

Certain root systems even have the ability to dissipate tidal energy through unique hydrological flows and divert the energy of water in different directions reducing risk of coastal damage. Yet, to date, few studies have examined the fluid dynamics such as flow structure and on mangrove roots.

For a study, published in the American Physical Society’s journal, Physical Review Fluids, researchers singled out the red mangrove tree (Rhizophora mangle) from more than 80 different species of mangroves, because of its robust network of roots that can withstand extreme environmental conditions. The red mangrove provided the researchers with an ideal model for bioinspired shoreline applications.

Internet by Google Balloons & Facebook Drones (Project Loon & Project Aquila)

Posted by in categories: drones, internet

This video is the second in a three-part series discussing global internet connectivity. In this video, we’ll be discussing the Earth-based, more specifically, stratosphere based initiatives to bring internet connectivity to the entire planet.

[0:30–5:30] Starting off we’ll take a look at Google’s bid to bring internet connectivity to the planet, dubbed, Project Loon. As well as, the importance of a hyper-connected society, for example, aiding in disaster relief efforts.

[5:30–9:30] Following that we’ll take a look at Facebooks initiative titled, Project Aquila. As well as, discuss the benefits of each initiative in bringing connectivity to the planet.

Inside the United Nations’ effort to regulate autonomous killer robots

Posted by in categories: drones, Elon Musk, existential risks, law, military, robotics/AI

Amandeep Gill has a difficult job, though he won’t admit it himself. As chair of the United Nations’ Convention on Conventional Weapons (CCW) meetings on lethal autonomous weapons, he has the task of shepherding 125 member states through discussions on the thorny technical and ethical issue of “killer robots” — military robots that could theoretically engage targets independently. It’s a subject that has attracted a glaring media spotlight and pressure from NGOs like Campaign to Stop Killer Robots, which is backed by Tesla’s Elon Musk and Alphabet’s Mustafa Suleyman, to ban such machines outright.

Gill has to corral national delegations — diplomats, lawyers, and military personnel — as well as academics, AI entrepreneurs, industry associations, humanitarian organizations, and NGOs in order for member states to try to reach a consensus on this critical security issue.

Scientists observe decay of Higgs boson particle into two bottom quarks

Posted by in category: particle physics

Aug. 28 (UPI) — Particle physicists have finally witnessed the decay of a Higgs boson particle into two bottom quarks.

Models predict Higgs boson particles decay into two bottom quarks 60 percent of the time. Bottom quarks, or b quarks, are the second heaviest of the six types of quarks.

Scientists have struggled to directly observe the predicted decay. Several types of proton-proton collisions can produce bottom quarks, making it difficult to link quarks produced by particle collisions with decaying Higgs boson particles.

Startup plans “gas stations” for satellite servicing

Posted by in categories: business, finance

WASHINGTON — A startup company planning to develop orbital propellant depots to assist satellite servicing ventures has raised an initial round of funding to support a first launch as soon as next year.

Orbit Fab, a Silicon Valley-based company with about a dozen employees, said Aug. 28 that a round of funding led by venture capital firm Bolt will enable it to demonstrate technology for fuel tanks that could be used by future satellite servicing systems.

“We differentiate ourselves from the satellite servicing operators in that we’re looking to put up just dumb tanks full of propellant, to provide that propellant where it’s needed, and we’re looking to partner with the satellite servicing operators to help improve their business models,” said Daniel Faber, chief executive of Orbit Fab, in an interview.
