Nanoparticles used to enhance chemotherapy Posted: 07 Jul 2014 01:17 PM PDT A new formulation of cisplatin, a common chemotherapy drug, has been developed by researchers that significantly increases the drug's ability to target and destroy cancerous cells. Cisplatin may be used to treat a variety of cancers, but it is most commonly prescribed for cancer of the bladder, ovaries, cervix, testicles and lung. It is an effective drug, but many cancerous cells develop resistance to the treatment.

Mystery of the printed diode solved Posted: 07 Jul 2014 01:16 PM PDT A thirteen-year-long mystery that has involved a long series of researchers has finally been solved. A new article presents a diode in printed electronics that works in the GHz band, which opens up a new opportunity to send signals from a mobile phone to, for example, printed electronic labels. Energy from the radio signal is collected and used to switch the label's display. The diode being printed means that it is both cheap and simple to manufacture. Researchers have long known that the diode works, but not how and why.

Patient patience and pandemics: How to keep patient choice up, stress down in a pandemic Posted: 07 Jul 2014 12:25 PM PDT Allowing patients to choose which hospital they attend when suffering illness during a pandemic rather than assigning them to a specific healthcare facility could be inefficient, according to research. But incentives might redress the balance. A new proposal is based on two assignment models. The first, a decentralized, equilibrium model, describes the patient choice of hospital. The second, centralized, non-linear programming model allows the health authority to maximize resource utilization of all the hospitals in a given region.

Neuroeconomists confirm Warren Buffett's wisdom: Brain research suggests an early warning signal tips off smart traders Posted: 07 Jul 2014 12:25 PM PDT Investment magnate Warren Buffett has famously suggested that investors should try to 'be fearful when others are greedy and be greedy only when others are fearful.' That turns out to be excellent advice, according to the results of a new study that looked at the brain activity and behavior of people trading in experimental markets where price bubbles formed.

Expectant moms turn to internet for pregnancy advice more than they would like Posted: 07 Jul 2014 12:25 PM PDT Pregnant women are using the Internet to seek answers to their medical questions more often than they would like, say researchers.

Building much smaller, greener electronics: Atom-scale, ultra-low-power computing devices to replace transistor circuits Posted: 07 Jul 2014 12:25 PM PDT The digital age has resulted in a succession of smaller, cleaner and less power-hungry technologies since the days the personal computer fit atop a desk, replacing mainframe models that once filled entire rooms. Desktop PCs have since given way to smaller and smaller laptops, smartphones and devices that most of us carry around in our pockets. Scientists are now developing atom-scale, ultra-low-power computing devices to replace transistor circuits.

Mathematical model illustrates our online 'copycat' behavior Posted: 07 Jul 2014 12:24 PM PDT Researchers examined how users are influenced in the choice of apps that they install on their Facebook pages by creating a mathematical model to capture the dynamics at play.

The quantum dance of oxygen: Proposal for a new phase of the element, when atoms dance in quartets Posted: 07 Jul 2014 12:23 PM PDT Under extremely high pressure conditions oxygen molecules group into quartets and give rise to a "dance of their magnetic moments". This results in magnetic properties never previously observed in these conditions and in theory points to the existence of a new phase of the element, called epsilon 1.

Understanding of how hearing works advanced by new research Posted: 07 Jul 2014 12:22 PM PDT Understanding how hearing works has long been hampered by challenges associated with seeing inside the inner ear, but technology being developed by a team of researchers is generating some of the most detailed images of the inner ear to date. Employing a technique that generates high-resolution, three-dimensional images, researchers are mapping the tissues within the cochlea, the portion of the inner ear responsible for hearing.

Satellites reveal possible catastrophic flooding months in advance Posted: 07 Jul 2014 11:17 AM PDT Data from NASA satellites can greatly improve predictions of how likely a river basin is to overflow months before it does, according to new findings. The use of such data, which capture a much fuller picture of how water is accumulating, could result in earlier flood warnings, potentially saving lives and property.

Solid-state physics: Consider the 'anticrystal' Posted: 07 Jul 2014 10:43 AM PDT For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make. Physicists now have evidence that a new concept should undergird our understanding of most materials: the anticrystal, a theoretical solid that is completely disordered.

Ultra-cold atom transport made simple Posted: 07 Jul 2014 09:15 AM PDT Techniques for controlling ultra-cold atoms traveling in ring traps currently represent an important research area in physics. A new study gives a proof of principle, confirmed by numerical simulations, of the applicability to ultra-cold atoms of a very efficient and robust transport technique called spatial adiabatic passage.

Efficient thermal cooling and heating Posted: 07 Jul 2014 09:14 AM PDT Thermal systems use heat to produce cold, and vice versa. To do so, a material is needed that can dissipate water vapor particularly well and quickly. A new method simply applies this property as a layer onto the components.

Supermassive black hole blows molecular gas out of a galaxy at one million kilometers per hour Posted: 07 Jul 2014 09:14 AM PDT New research has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way. The supermassive black holes in the cores of some galaxies drive massive outflows of molecular hydrogen gas. As a result, most of the cold gas is expelled from the galaxies. Since cold gas is required to form new stars, this directly affects the galaxies' evolution.

Taking a short smartphone break improves employee well-being, research finds Posted: 07 Jul 2014 09:13 AM PDT Short smartphone breaks throughout the workday can improve workplace productivity, make employees happier and benefit businesses, a researcher reports. "By interacting with friends or family members through a smartphone or by playing a short game, we found that employees can recover from some of their stress to refresh their minds and take a break," the researcher said.

University students developing robotic gardening technology Posted: 07 Jul 2014 08:35 AM PDT For more than a half-century, NASA has made the stuff of science fiction into reality. Researchers are continuing that tradition by designing robots to work in a deep-space habitat, tending gardens and growing food for astronaut explorers. It sounds like a concept from Star Wars, but a team of graduate students from the University of Colorado Boulder is now developing the innovative technology to make it possible.

From antibiotics to yeast: Latest student science heads for space Posted: 07 Jul 2014 08:32 AM PDT Astronauts on future missions may nibble on lettuce and grow their own antibiotics, depending on the results of research that student scientists plan to conduct on the International Space Station. Mission 5 of the Student Spaceflight Experiments Program (SSEP) is scheduled to launch to the space station on July 11. A total of 1,344 proposals yielded 15 selected investigations for the flight. These investigations represent a diversity of subject matter from bacteria to tadpole shrimp and locations from Massachusetts to Arizona.

Platonic solids generate their four-dimensional analogues Posted: 07 Jul 2014 07:36 AM PDT Platonic solids are regular bodies in three dimensions, such as the cube and icosahedron, and have been known for millennia. They feature prominently in the natural world wherever geometry and symmetry are important, for instance in lattices and quasi-crystals, as well as fullerenes and viruses. Platonic solids have counterparts in four dimensions, and mathematicians have now shown that there are six of them, five of which have very strange symmetries.

Small, but plentiful: How the faintest galaxies illuminated the early universe Posted: 07 Jul 2014 06:24 AM PDT Astronomers investigating the behavior of the universe shortly after the Big Bang have made a surprising discovery: the properties of the early universe are determined by the smallest galaxies.

Athena Observatory helping solve mysteries of the universe Posted: 07 Jul 2014 06:24 AM PDT The European Space Agency (ESA) has selected the Athena X-ray Observatory as its second 'Large-class' science mission in the 21st Century, which will help answer vital questions about the universe.

DNA origami nano-tool provides important clue to cancer Posted: 07 Jul 2014 06:24 AM PDT Researchers have headed a study that provides new knowledge about the EphA2 receptor, which is significant in several forms of cancer. This is important knowledge in itself – but just as important is how this study was conducted. The researchers used the method of DNA origami, in which a DNA molecule is shaped into a nanostructure, and used these structures to test theories about cell signalling.

'Nanojuice' could improve how doctors examine the gut Posted: 06 Jul 2014 12:33 PM PDT A new imaging technique involving nanoparticles suspended in liquid to form 'nanojuice' that patients would drink holds promise for the examination of the gut. Upon reaching the small intestine, doctors would strike the nanoparticles with a harmless laser light, providing an unparalleled, non-invasive, real-time view of the organ.

Chip developed for rapid detection of dengue fever Posted: 05 Jul 2014 11:00 AM PDT A chip (also known as cDNA microarray) has been developed that allows detection of the RNA strand of the dengue fever virus. The genetic information contained in this scientific tool pinpoints the exact serotype of malaria that an infected person or mosquito is carrying.

Monitoring neighborhood electricity consumption over 24 hour cycle Posted: 04 Jul 2014 10:46 AM PDT With more and more households owning one or even two electric cars requiring charging overnight, how will we manage it without sacrificing our hot morning shower and fresh bread for breakfast? This is the headache now facing the electricity supply companies. But this isn't their only problem. What use is it to those homeowners, who have installed a modest solar panel system on their roofs, when the sun is heating the pavement in the middle of the day and no one is at home to use the energy?
