Why You Need a Mobile Database

Posted by in category: futurism

A big reason for the high rate of app abandonment is bad experience, particularly slowness and unreliability. A report by Think Storage Now found that 70% of mobile app users will abandon an app that takes too long to load. And an older but still often cited Compuware study found that 84% of app users will abandon an app if it fails just two times.

These facts help emphasize that the margin of error is small when it comes to keeping users happy and engaged. Providing a fast, reliable experience is key to the success of your mobile app, and using the right database — one built for mobile apps — is key to achieving it.

Tata Motors launches $10,000 electric car

Posted by in categories: sustainability, transportation

Tata Motors, an India-based automaker, has launched a new small hatchback all-electric vehicle starting at just over $10,000.

The Indian auto market has been lagging behind its peers when it comes to electrification.

This is due to many factors, but not the least of which is the fact that the country has strong protectionist laws when it comes to its auto industry and it makes it hard for foreign automakers to launch new vehicles in the country without producing them there.

BREAKING: Three new unusual particles have been found by the Large Hadron Collider

Posted by in category: particle physics

The Large Hadron Collider beauty (LHCb) collaboration has announced the discovery of three new exotic particles.

Exotic particles, such as these, had only been theorized but not observed until recently. These exotic particles are built out of quarks.

Deficiency of Alternative Models to the Big Bang

Posted by in category: alien life

Hossenfelder lists several theories that fall under her critique including Penrose’s cyclic cosmology, the ekpyrotic universe that postulates colliding membranes, and the no-boundary proposal by Jim Hartle and Stephen Hawking. Stephen Meyer also critiqued these theories in his book Return of the God Hypothesis. But Meyer came to starkly different conclusions.

Hossenfelder concludes that “we are facing the limits of science itself.” And the question of the universe’s origin “we’ll never be able to answer.” In contrast, Meyer argues that the evidence for a beginning and the required fine tuning of the universe to support life point to a mind behind our world. The fact that all alternative cosmological theories require highly specific initial conditions to explain our present life-friendly universe only reinforces the fine-tuning argument and by extension the God Hypothesis.

New theory upends what we know about how charged macromolecules self-assemble

Posted by in categories: bioengineering, biotech/medical

In a discovery with wide-ranging implications, researchers at the University of Massachusetts Amherst recently announced in the Proceedings of the National Academy of Sciences that uniformly charged macromolecules—or molecules, such as proteins or DNA, that contain a large number of atoms all with the same electrical charge—can self-assemble into very large structures. This finding upends our understanding of how some of life’s basic structures are built.

Traditionally, scientists have understood charged polymer chains as being composed of smaller, uniformly charged units. Such chains, called , display predictable behaviors of self-organization in water: They will repel each other because similarly charged objects don’t like to be close to each other. If you add salt to water containing polyelectrolytes, then molecules coil up, because the chains’ electrical repulsion is screened by the salt.

However, “the game is very different when you have dipoles,” says Murugappan Muthukumar, the Wilmer D. Barrett Professor in Polymer Science and Engineering at UMass Amherst, the study’s senior author.

Engineers discover new process for synthetic material growth, enabling soft robots that grow like plants

Posted by in categories: biotech/medical, chemistry, robotics/AI

An interdisciplinary team of University of Minnesota Twin Cities scientists and engineers has developed a first-of-its-kind, plant-inspired extrusion process that enables synthetic material growth. The new approach will allow researchers to build better soft robots that can navigate hard-to-reach places, complicated terrain, and potentially areas within the human body.

The paper is published in the Proceedings of the National Academy of Sciences (PNAS), a peer-reviewed, multidisciplinary, high-impact scientific journal.

Raytheon Intelligence & Space and Kord team-up to defeat multiple mortars and large drones with Stryker-mounted high-energy laser

Posted by in categories: business, drones, energy, military, space

LAS CRUCES, N.M., May 16, 2022 /PRNewswire/ — In four weeks of continuous live-fire exercises, an industry team led by Raytheon Intelligence & Space, a Raytheon Technologies (NYSE: RTX) business, and Kord, a wholly owned subsidiary of KBR, defeated multiple 60mm mortar rounds with a 50kW-class high energy laser integrated on a Stryker combat vehicle.

The directed energy weapon system — part of the U.S. Army’s Directed Energy Maneuver-Short Range Air Defense, or DE M-SHORAD — acquired, tracked, targeted and defeated multiple mortars and successfully accomplished multiple tests simulating real-world scenarios.

Continuing to put the DE M-SHORAD system to the test, the recent operational assessment at White Sands Missile Range also included defeating several small, medium and large drones.
