Stomach hormone turns hungry people into junkies

May 7, 2008

When volunteers received a dose of a natural hunger-inducing hormone called ghrelin, their brains responded to pictures of food in the same way that addicted people’s brains do to cigarettes or drugs, says Alain Dagher, a neurologist at McGill University.

Made in the stomach, ghrelin levels rise when people are hungry and wane after a meal. This mechanism probably helped humans to load up on life-saving calories when food… read more

Stomach-acid-powered micromotors tested in living animal

January 28, 2015

Zinc stomach micromotors

Imagine a micromotor fueled by stomach acid that can take a bubble-powered ride inside a mouse — and that could one day be a safer, more efficient way to deliver drugs or diagnose tumors for humans.

That’s the goal of a team of researchers at the University of California, San Diego.

The experiment is the first to show that these micromotors can operate safely in… read more

Stomach-proof gel hints at jab-free diabetes treatment

April 22, 2008

University of Texas at Austin researchers have developed a gel that can smuggle insulin past the stomach and slowly release the drug into the blood, doing away with diabetics’ daily injections.

The team created a new water-based gel using nanoparticles of two polymers. When formed into particles around 100 nanometers across and combined with water, the polymers form a flexible hydrogel that can soak up insulin.

When put… read more

‘Stop watching us’ rally protests surveillance

October 25, 2013


On October 26th, the 12th anniversary of the signing of the USA Patriot Act, — a coalition of more than 100 public advocacy organizations and companies from across the political spectrum — is holding the largest rally yet against NSA surveillance.

According to
The revelations about the National Security Agency’s surveillance apparatus, if true, represent a stunning abuse of our basic rights. We demand the… read more

Storage Projects Rise in Importance

January 2, 2008

Private-sector archive capacity will hit 27,000 petabytes (27 billion gigabytes) by 2010, according to a study by Enterprise Strategy Group Inc.

Skyrocketing rates of e-mail growth account for much of this figure.

Storage system dramatically speeds access to ‘big data’

February 3, 2014


MIT researchers have developed a storage system for big-data analytics that can dramatically reduce the time it takes to access information by using a network of flash storage devices.

Currently, information tends to be stored on multiple hard disks on a number of machines across an Ethernet network.

With the new flash-based storage system, data in a large dataset can typically be randomly accessed in microseconds. That’s about… read more

Store 256GB on an A4 sheet

November 27, 2006

New “rainbow technology” allows data to be encoded into colored geometric shapes and stored in patterns on paper or or plastic sheets at a density of 2.7GB per square inch and and then played back through a computer with a special scanner attached.

Storing data for the next 1000 years

April 23, 2008

Researchers from the University of California Santa Cruz have developed the idea of Pergamum, a new disk-based approach for archiving data.

Pergamum uses both intra-disk and inter-disk redundancy to guard against data loss, relying on hash tree-like structures of algebraic signatures to efficiently verify the correctness of stored data.

They believe a 10 petabytes storage system could be built for about $4700, with an annual operational cost (power… read more

Storing data in individual molecules near room temperature

January 24, 2013


An experimental technology called molecular memory could store data in individual molecules has been developed by an international team of researchers led by Jagadeesh Moodera, a senior research scientist in the MIT Department of Physics and at MIT’s Francis Bitter Magnet Laboratory,

The technology promises a 1,000-fold increase in storage density over hard disks, which are approaching a million megabytes of… read more

Storing data using your body

Sparsh: Copying pictures from a phone to a tablet computer (credit: Pranav Mistry)

Researchers at the MIT Media Lab have developed an application called Sparsh that allows users to store data using their bodies (metaphorically speaking).

Sparsh lets you touch a data item to copy data from a smartphone, tablet, or laptop, using Dropbox or an FTP account to temporarily “store” it, and then touch a second device and paste the saved content. (The actual data transfer happens in the cloud.)… read more

Storing light with sound

December 14, 2007

Duke University researchers have demonstrated a way to store the information in a beam of light by converting it into a sound signal, then reading it back out again as light.

The process could avoid the heat generated when buffering via electronic signals, which limits the top speed of fiber-optic-signals.

Storing short movie in a cloud of gas may lead to quantum memory

Researchers have been able to store a single image in a cloud of rubidium atoms for several years. Now they’ve gone a step further by storing two images at the same time, Technology Review Physics arXiv Blog reports.

One of the enabling technologies for a quantum Internet is the ability to store and retrieve quantum information in a reliable and repeatable way.

One way to do… read more

Storing Solar Power Efficiently

September 27, 2007

Thermal-power plants could solve some of the problems with solar power outages by turning sunlight into steam and storing heat for cloudy days.

Storing solar, wind, and water energy underground could replace burning fuel

November 23, 2015

WWS solution

Stanford and UC Berkeley researchers have a solution to the problem of storing energy from wind, water and solar power overnight (or in inclement weather): store it underground. The system could result in a reliable, affordable national grid, replacing fossil fuel, they believe.

How it would work

  • Summer heat gathered in rooftop solar collectors could be stored in soil or rocks and used for heating
