Scots scientists unveil ‘spray-on’ computer

April 10, 2007

Scottish scientists have developed a computer the size of a matchstick head, thousands of which can be sprayed onto patients to give a comprehensive analysis of their condition.

The individual appliances, or “specks,” will form networks that can be programmed like ordinary computers.

Spraying them directly onto a person creates the ability to carry out different tests at the same time, for example muscle movement and pulse rate.… read more

Screening the Latest Bestseller

January 23, 2006

The new Sony Reader e-book features a display that looks more like ordinary paper than a liquid crystal display, because the pixels reflect ambient light rather than transmit light from behind. There’s no flicker, because the pixels are completely static.

The E Ink technology also conserves batteries because current is used only when pixels need to change their color — between virtual page turns, the Reader consumes no current… read more

Screensaver reveals new test for synaesthesia

August 5, 2008

Caltech scientist Melissa Saenz has found that with certain visual stimuli, from moving dots to flashes of light, people described simple abstract sounds such as tapping, thumping, whirring or whooshing.

Scientists at The Scripps Research Institute have discovered a surprisingly simple and safe method to disrupt specific genes within cells. The scientists highlighted the medical potential of the new technique by demonstrating its use as a safer alternative to an experimental gene therapy against HIV infection.

“We showed that we can modify the genomes of cells without the troubles that have long been linked to… read more

Scripps Research Institute study suggests expanding the genetic alphabet may be easier than previously thought

A new study led by scientists at The Scripps Research Institute suggests that the replication process for DNA — the genetic instructions for living organisms that is composed of four bases (C, G, A and T) — is more open to unnatural letters than had previously been thought.

An expanded “DNA alphabet” could carry more information than natural DNA, potentially coding for a much wider… read more

Scripps Research scientists produce first stem cells from endangered species

Drill primate

Scientists from The Scripps Research Institute have produced the first stem cells from endangered species, starting with normal skin cells.

Such cells could eventually make it possible to improve reproduction and genetic diversity for some species, possibly saving them from extinction, or to bolster the health of endangered animals in captivity.

They experimented with two endangered species: the drill and the northern white rhinoceros.… read more

Scripps Research study points to liver, not brain, as origin of Alzheimer’s plaques

March 4, 2011

Unexpected results from a Scripps Research Institute and ModGene, LLC study could completely alter scientists’ ideas about Alzheimer’s disease—pointing to the liver instead of the brain as the source of the “amyloid” that deposits as brain plaques associated with this devastating condition. The findings could offer a relatively simple approach for Alzheimer’s prevention and treatment.

The study was published online today in The Journal of Neuroscience Research.

Scripps Research study presents surprising view of brain formation

February 10, 2011

A study from The Scripps Research Institute has unveiled a surprising mechanism that controls brain formation. The findings have implications for understanding a host of diseases, including some forms of mental retardation, epilepsy, schizophrenia, and autism.

The research, led by Scripps Research Professor Ulrich Mueller, was published in the journal Neuron on February 10, 2011.

In the new study, Mueller and colleagues focused on a protein called reelin. They… read more

Sculpting a Nano ‘World’

April 30, 2010

World map with 500,000 pixels and 15-nanometer features drawn in just two minutes (Advanced Materials)

IBM researchers have invented a low-cost, fast, and relatively simple fabrication tool capable of reliably creating 3-D features as small as 15 nanometers.

The silicon tip is cantilevered like those used in atomic force microscopy (AFM), enabling it to apply nanonewtons of force to the surface. But unlike AFM, the tip is heated, so when it touches the substrate, the thermal energy at the tip is sufficient to break… read more

Sea coral tags proteins in cells

March 20, 2006

The glow emitted by Dendra, derived from the sea coral Dendronephthya, makes it possible to precisely label an object, such as a cell, organelle, or protein, with a flash of light and then to follow the object’s movement over time.

The light source of the laser-scanning confocal microscopes that researchers commonly use to peer into living cells can activate the tag, which should make the new tool useful to… read more

Sea Cucumber Protein Used To Inhibit Development Of Malaria Parasite

January 3, 2008

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut, which impairs the development of malaria parasites, a step towards preventing malaria transmission.

In laboratory tests, the international research team showed that the method significantly impaired the parasite’s development.

Sea level rise ‘locking in’ quickly, cities threatened

July 30, 2013

climate_change_threatens_cities

Measurements tell us that global average sea level is currently rising by about 1 inch per decade. But in an invisible shadow process, our long-term sea level rise commitment or “lock-in” — the sea level rise we don’t see now, but which carbon emissions and warming have locked in for later years — is growing 10 times faster, and this growth rate is accelerating, writes Benread more

Sea level rise: It’s worse than we thought

July 2, 2009

The continued melting of glaciers and ice caps outside of Greenland and Antarctica will add another 10 to 20 centimeters to sea level by 2100, according to one report.

Sea of dreams: Genetically modified microbes will lead to a revolution in industrial biotechnology

May 4, 2004

Industrial biotechnology, where cells from genetically modified organisms are used to generate industrially useful products, is a phenomenon that will shake up the chemical industry and eventually rock entire economies because biotechnological processes are cheaper than traditional chemistry, have higher yields or produce a cleaner product.

Examples of new products generated with this method include methionine, an amino-acid animal-feed supplement with a market worth $1.4 billion a year; turning… read more
