Researchers model avalanches in two dimensions

Posted by in category: food

There’s a structural avalanche waiting inside that box of Rice Krispies on the supermarket shelf. Cornell researchers are now closer to understanding how those structures behave — and in some cases, behave unusually.

The researchers, led by James Sethna, professor of physics in the College of Arts and Sciences, have for the first time rendered a model for crackling noise in two dimensions. Their paper, “Unusual Scaling for Two-Dimensional Avalanches: Curing the Faceting and Scaling in the Lower Critical Dimension,” was published Oct. 30 in Physical Review Research. The paper’s lead author was Lorien X. Hayden, M.S. ‘15, Ph.D. ‘19, and co-author was Archishman Raju, M.S. ‘16, Ph.D. ‘18.

Milk enters Rice Krispies through a process known as “fluid invasion,” which is similar to the oil industry’s method of pumping pressurized water into porous sandstone to push out oil. The resulting noise — the cereal’s famous “snap, crackle and pop” — is a type of tiny “avalanche” that indicates a burst of milk invading pores in the puffed rice. Each avalanche is essentially composed of smaller-scale versions of itself, a proportionality shaped by “power law” distribution. Crackling noise also describes earthquakes, magnets and many other systems.

DSU gets nearly $240,000 research grant from Army

Posted by in categories: biotech/medical, military, quantum physics

The Department of Defense has awarded Dr. Gour Pati, professor of Physics and Engineering at Delaware State University a $239,908 grant from the U.S. Army to develop and build a millimeter-wave quantum sensing system at DSU.

Dr. Pati – the principal investigator – and his researchers have recognized the increasing importance of millimeter-wave sensing and imaging in commercial and military sectors, as well as how it is driving the development of low-cost sensors. Dr. Pati’s success in winning the DoD grant engages DSU scientists and students in the work of furthering this advancement.

Rydberg atoms have a hypersensitive response to microwave, millimeter-wave and terahertz radiation. They have the potential for applications in modern communications, remote sensing and many other fields, including medical science. Pati and his team will develop a real-time millimeter-wave sensor using laser-induced fluorescence in Rydberg atoms.

How Gene Therapy Is Evolving to Tackle Complex Diseases

Posted by in categories: biotech/medical, genetics

Gene therapy has traditionally been applied to well-understood diseases where a single genetic mutation was to blame. A new generation of technology is expanding the potential of gene therapy to treat conditions that were previously unreachable. Since the first gene therapy clinical trials in the 1990s, the technology has made its way into the market for conditions ranging from blindness to cancer. Gene therapy has the potential to fix any genetic mutation causing disease by inserting a new copy of the faulty gene. However, its reach has historically been limited. We’ve been constrained with the things we.

Science must move with the times

Posted by in categories: futurism, science

But Manichean views and tropes of ‘dual use’ miss the point. Some of the key questions that confront science today are about whether its methods, practices and ethos, pursued with very little real change since Maxwell’s day, are fit for purpose in the light of the challenges — conceptual and practical — we now face. Can science continue to fulfil its social contract and to reach new horizons by advancing on the same footing into the future? Or does something need to shift?


Research cannot fulfil its social contract and reach new horizons by advancing on the same footing into the future, argues Philip Ball in the last essay of a series on how the past 150 years have shaped today’s science system, to mark Nature’s anniversary.

What are the best foods to fight aging?

Posted by in categories: food, life extension

Please read 🙂.


Eat well for a long and healthy life – that’s a mantra that we’re all familiar with, but what are the best foods to help us achieve that goal? In this article, we give you an overview of some of the most healthful and nutritious foods.

Official figures indicate that, currently, the top three countries in the world with the highest life expectancy are the Principality of Monaco, Japan, and Singapore. These are places where the inhabitants experience a high quality of life, and an important element of that is eating healthful meals.

Newly Discovered Android Malware Can Survive A Factory Reset

Posted by in categories: cybercrime/malcode, mobile phones

Malware on our smartphones isn’t new, and while there are ways to remove them, in some instances where it is particularly severe, the only way to deal with malware would be to factory reset your phone back to the way it was when it was new. Unfortunately, it seems that there is a new Android malware making its rounds that makes it impossible to remove, even with a factory reset.

Dubbed xHelper, this malware isn’t so much about stealing your phone’s information or sensitive details, but rather, it is designed to continuously serve up popup ads, in which presumably that is how its creators are making money off it. There is one particularly dangerous feature of the malware, which according to ZDNet, would see the malware download and install apps on your behalf.

As if that wasn’t bad enough, as we said, the malware cannot be uninstalled or removed even if you factory reset your phone. According to security companies like Symantec and Malwarebytes, they believe that the reason why this app is so persistent is because of a system app that might have been compromised.

ROME (Thomson Reuters Foundation) — It may sound like science fiction, but in a few short years the family dinner table may be laden with steak from a printer and other proteins produced from air, methane or volcanic microbes.

With the explosive success of vegan beef and burger substitutes developed by Beyond Meat and Impossible Foods, the alternative protein sector just keeps growing.

According to investment bank Barclays, alternative meat sales could reach $140 billion — or 10% of the global meat industry — within a decade, or a 10-fold increase from current levels.
