Cartilage, for example, is a hard material that caps the ends of bones and allows joints to work smoothly, but engineered replacement tissue is, mechanically, far from native tissue. Researchers in California report the use of an enzyme that has greatly improved engineering cartilage built from cultures. It promotes cross-linking and makes the material stronger.
Traumatized by the world's worst nuclear disaster since Chernobyl and encouraged by the highest rates for renewable energy in the world, Japan has been undergoing a green boom. It's now rapidly turning into a fiasco as the cost proves prohibitive and utilities anticipate putting some nuclear reactors back online. The utilities say they can't accommodate the flood of newcomers to the green energy business.
The heart holds its own pool of immune cells capable of helping it heal after injury, according to new research in mice at Washington University School of Medicine in St. Louis. When the heart is injured, beneficial immune cells are often supplanted by bone marrow cells, which cause damaging inflammation. In a mouse model, researchers showed that blocking the bone marrow’s macrophages protects the organ’s beneficial pool of macrophages.
Nikon Instruments, Inc. has revealed the winners of the 40th annual Nikon Small World Photomicrography Competition, awarding first prize to veteran competitor Rogelio Moreno of Panama for capturing a rarely seen image of a rotifer’s open mouth interior and heart-shaped corona.

With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. In ACS Nano, they describe new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel.
By remotely "combing" the atmosphere with a custom laser-based instrument, researchers from NIST, in collaboration with researchers from the National Oceanic and Atmospheric Administration (NOAA), have developed a new technique that can accurately measure—over a sizeable distance—amounts of several of the major "greenhouse" gases implicated in climate change.
People with muscular dystrophy could one day assess the effectiveness of their medication with the help of a smartphone-linked device, a new study in mice suggests. The study used a new method to process ultrasound imaging information that could lead to hand-held instruments that provide fast, convenient medical information.
Imagine being able to precisely control specific tissues of a plant to enhance desired traits without affecting the plant’s overall function. Thus a rubber tree could be manipulated to produce more natural latex. Trees grown for wood could be made with higher lignin content, making for stronger yet lighter-weight lumber.
A team led by the Lawrence Livermore National Laboratory scientists has created a new kind of ion channel consisting of short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA. These carbon nanotube “porins” have significant implications for future health care and bioengineering applications.
Astronomers have caught their first glimpse of the invisible magnetic fields that sculpt solar systems. Looking at a bright, nearby baby star and the dust swirling in its cradle, astronomers from the Univ. of Illinois and six collaborating institutions were able to make out the shape of the magnetic field surrounding the star.
As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.
Inside Massachusetts Institute of Technology’s Building 41, a small, Roomba-like robot is trying to decided where to go. As the robot considers its options, its “thoughts” are projected on the ground in the form of different colored dots and lines. This new visualization system, called “measurable virtual reality”, combines projectors with motion-capture technology and animation software to project a robot’s intentions in real time.
If the surroundings are designed to be sufficiently stimulating, even a simple computer screen is enough to generate an intense cinematic experience. After observing some 300 study subjects, researchers in Germany have concluded that the angle of viewing does not play a vital role in the cinematic experience. Instead, the presence of so-called contextual visual cues plays a greater role in actually drawing viewers into a movie.
An overwhelming number of chemicals from household and industrial products are in the environment, and hundreds are in our bodies. But for most of them, scientists have yet to determine whether they cause health problems. Now they’ve taken the first step toward doing that by estimating which substances people are exposed to the most.
Electrical engineers from the Univ. of California, San Diego have developed hardware for a new generation of automotive radar systems designed to keep drivers, and the pedestrians around them they may not see, safe. Their project is part of an initiative led by Toyota Technical Center that won a 2014 R&D 100 Award for its “Automotive Phased Array Radar.”
Researchers in Japan have directly observed and recorded electron flow at 80,000 m/sec in a semiconductor. They did so by combining a new laser pulse light source and a photoemission electron microscope to develop an ultra high-speed microscope that enabled visualization of electrons on a 20 nm and 200 femtosec scale.
An accumulation of amyloid-beta proteins deposits called plaques is known to cause Alzheimer’s disease. One aspect of this illness that has not received much attention is which role the structure of the brain environment plays. Researchers have discovered that macromolecules like astrocytes provide well-defined physical cues in the form of ruffles that have a crucial role in promoting healthy interactions between cells in the hippocampus.
The company behind the dramatic launch explosion of a space station supply mission promises to find the cause of the failure and is warning residents to avoid any potentially hazardous wreckage. Orbital Sciences Corp.'s unmanned Antares rocket blew up just moments after liftoff Tuesday evening from the Virginia coast.
Researching the safety of nanoparticles is all the rage. Thousands of scientists worldwide are conducting research on the topic, examining the question of whether titanium dioxide nanoparticles or carbon nanotubes can get into the body’s lungs or blood. However, the amount of new knowledge has only increased marginally. How do nanoparticles get into the body? Researchers in Switzerland are attempting to establish standards.
Given today’s widespread use of Raman spectroscopy, it can be hard to believe Raman was a highly specialized analytical technique for most of its history. The technique’s potential was recognized from the beginning: When Raman scattering was first observed in 1928, it was widely believed to be one of the most important scientific discoveries of the 20th century to date.
The condition of an athlete's heart has for the first time been accurately monitored throughout the duration of a marathon race. The real-time monitoring was achieved by continuous electrocardiogram (ECG) surveillance and data transfer over a public mobile phone network. The new development allows instantaneous diagnosis of potentially fatal rhythm disorders.
A team led by Virginia Tech researchers studied cells found in breast and other types of connective tissue and discovered new information about cell transitions that take place during wound healing and cancer. They developed mathematical models to predict the dynamics of cell transitions, and by comparison gained new understanding of how a substance known as transforming growth factor triggers cell transformations.
DEET has been the gold standard of insect repellents for more than six decades, and now researchers led by a Univ. of California, Davis, scientist have discovered the exact odorant receptor that repels them. They also have identified a plant defensive compound that might mimic DEET, a discovery that could pave the way for better and more affordable insect repellents.
Cancer researchers have found that a simple blood test might help diagnose pancreatic cancer, one of the most deadly forms of the disease.
