Cassini Pinpoints Source Of Jets On Saturn's Moon Enceladus (August 15, 2008) -- In a feat of interplanetary sharpshooting, NASA's Cassini spacecraft has pinpointed precisely where the icy jets erupt from the surface of Saturn's geologically active moon Enceladus. New carefully targeted pictures reveal exquisite details in the prominent south polar "tiger stripe" fractures from which the jets emanate. ... > full story
Slipping Through Cell Walls, Nanotubes Deliver High-potency Punch To Cancer Tumors In Mice (August 15, 2008) -- A big challenge in treating cancer with chemotherapy is how to get the most medication into the cells of a tumor without "spillover" of the medication adversely affecting the healthy cells in a patient's body. Now researchers have addressed that problem using single-walled carbon nanotubes as delivery vehicles. This method gets a higher proportion of a given dose of medication into the tumor cells than is possible with the "free" drug. ... > full story
Chemists Take Gold, Mass-produce Beijing Olympic Logo (August 15, 2008) -- Nanoscientists have mass-produced the 2008 Summer Olympics logo -- 15,000 times. All the logos take up one square centimeter of space. The researchers printed the logos as well as an integrated gold circuit using a new printing technique, called Polymer Pen Lithography, that can write on three different length scales using only one device. It is fast, inexpensive and simple and could find use in computational tools, medical diagnostics and the pharmaceutical industry. ... > full story
New Nanomaterial Makes Plastic Stiffer, Lighter And Stronger (August 15, 2008) -- Scientists have developed a nanomaterial that makes plastic stiffer, lighter and stronger and could result in more fuel-efficient airplanes and cars as well as more durable medical and sports equipment. ... > full story
Partial Lunar Eclipse On 16th August (August 15, 2008) -- People across the world will have the chance to see a partial eclipse of the Moon on the 16th August. ... > full story
Phoenix Microscope Takes First Image Of Martian Dust Particle (August 15, 2008) -- NASA's Phoenix Mars Lander has taken the first-ever image of a single particle of Mars' ubiquitous dust, using its atomic force microscope. The particle -- shown at higher magnification than anything ever seen from another world -- is a rounded particle about one micrometer, or one millionth of a meter, across. It is a speck of the dust that cloaks Mars. Such dust particles color the Martian sky pink, feed storms that regularly envelop the planet and produce Mars' distinctive red soil. ... > full story
Structural Biology Spin-out Tackles Major Diseases (August 15, 2008) -- A spin off company from basic structural biology has led to new technology that provides a way of creating therapeutic proteins to tackle major diseases such as cancer, diabetes and infertility. ... > full story
Towards Zero Training For Brain-computer Interfacing (August 15, 2008) -- While invasive electrode recordings in humans show long-term promise, noninvasive techniques can also provide effective brain-computer interfacing and localization of motor activity in the brain for paralyzed patients with significantly reduced risks and costs as well as novel applications for healthy users. However, two issues hamper the ease of use of BCI systems based on noninvasive recording techniques, such as electroencephalography. ... > full story
To The Moon And Mars: Psychologists Show New Ways To Deal With Health Challenges In Space (August 14, 2008) -- As NASA prepares to send humans back to the moon and then on to Mars, psychologists are exploring the challenges astronauts will face on missions that will be much longer and more demanding than previous space flights. Psychologists outlined these mental health challenges at the American Psychological Association's 116th Annual Convention, and introduced a new interactive computer program that will help address psychosocial challenges in space. ... > full story
Solar Collector Could Change Asphalt Roads Into Renewable Energy Source (August 14, 2008) -- Scientists have found a way to use asphalt's heat-soaking property for an alternative energy source by developing a solar collector that could turn roads and parking lots into ubiquitous -- and inexpensive sources of electricity and hot water. ... > full story
Bouncy Cell Phones And Car Bumpers May Be Workable With Springy Nanotubes (August 14, 2008) -- Electronic devices get smaller and more complex every year. It turns out that fragility is the price for miniaturization, especially when it comes to small devices, such as cell phones, hitting the floor. Wouldn't it be great if they bounced instead of cracked when dropped? ... > full story
Robot With A Biological Brain: New Research Provides Insights Into How The Brain Works (August 14, 2008) -- Researchers in the UK have developed a robot which is controlled by a biological brain formed from cultured neurons -- the first step to examine how memories manifest themselves in the brain, and how a brain stores specific pieces of data. The key aim is that eventually this will lead to a better understanding of development and of diseases and disorders which affect the brain such as Alzheimer's Disease, Parkinson's Disease, stoke and brain injury. ... > full story
