Temporary glues may not steal headlines, but they can make everyday life easier.


Sticky office notes, bandage strips and painter’s tape are all examples of products that adhere to surfaces but can be removed with relative ease.

There’s only one drawback. To remove any of those adhesives, the glued surfaces need to be pulled apart from each other.

Dartmouth research has discovered a class of molecular materials that can be used to make temporary adhesives that don’t require force for removal. These non-permanent glues won’t be available as home or office supplies, but they can lead to new manufacturing techniques and pharmaceutical design.

“This temporary adhesive works in an entirely different way than other adhesives,” said Katherine

The MSCI Asia Pacific Index, which has just posted its best monthly return since 2009 with a 10.2% rally in November, may remain robust in December, based on its track record over the past decade. Since 2010, the benchmark gauge has averaged a 1% gain in the final month of the year, double the performance of the S&P 500 in December, according to data compiled by Bloomberg.

A memory revolution: we explore how flash changed the world and what the future holds

Of course, it’s not quite that simple. In fact, by 2000 Samsung had already been experimenting with flash and its predecessors for the best part of two decades. In that time the company’s engineers had quietly refined and improved the technology, steadily increasing its speed and storage capacity. In 1994, Samsung released the first 16Mb NAND flash. In 1999 it created the first NAND flash with 1Gb of storage.

A role for flash?

The question was, what to do with it? In the early days of flash, real world applications for the technology were thin on the ground. In the late 1980s, a predecessor of flash (Mask ROM) had found a market in electronic dictionaries and early handheld gaming devices, like Game Boy and Tamagotchi. By the turn of the century, flash had become ubiquitous in other small consumer devices, like digital cameras and the first generation of portable digital

Vaccine Rally Extends To Tech Stocks As Broader Market Holds Gains, But Uncertainty Lies Ahead

Topline

The market rally tied to Pfizer’s promising vaccine announcement continued for a third day on Wednesday, with the Nasdaq posting gains for the first time this week, but the dampening prospects of fiscal stimulus and policy action in the coming weeks amid ongoing record-high coronavirus cases could seriously hinder the economic recovery.

Our galaxy holds at least 300 million potentially habitable planets, NASA finds

Our galaxy is filled with potentially habitable planets — at least 300 million of them, according to NASA.

After nine years in deep space collecting data that revealed our night sky to be filled with billions of hidden planets — more planets even than stars — NASA’s Kepler space telescope ran out of fuel needed for further science operations in 2018.

The US space agency’s Kepler Space Telescope spent nine years on a planet-hunting mission, successfully identifying thousands of exoplanets in our galaxy before running out of fuel in 2018. But the original mission’s core question remained: how many of these planets are habitable?
