Credit: Esko Kauppinen, et al. Researchers have created a hybrid carbon nanomaterial that merges single-walled carbon nanotubes and spherical carbon-atom cages called fullerenes. The new structures, dubbed NanoBuds because they …

Cold Fusion continues to gain Grudging Respect

Cold Fusion continues to claw its way to respectability American Chemical society is holding a symposium at their national meeting in Chicago, Illinois, on ‘low-energy nuclear reactions’, the official name for cold fusion. Vocal cold-fusion critic Robert Park at the University of Maryland. “If anything is going on, it’s not fusion.” That cold-fusion critics such …

Penn scientists engineer small molecules to probe proteins deep inside cell membrane

Proteins, which form much of the molecular machinery required for life, are the targets of most drug molecules. One third of all proteins are membrane proteins – embedded within the cell’s fatty outer layer. While scientists can easily study the other two-thirds using such tools as antibodies, they have not had such methods to investigate …

Medical progress summary

Japanese scientists have developed an oral vaccine for Alzheimer’s disease that has proven effective and safe in mice. “We hope the Phase I trials go well,” Tabira said. “Animals are able to recover their functions after developing symptoms, but humans are less able to do so. It may be that this only works in the …

Progress in Nanotube Transistors

High-current transistors made from perfectly aligned carbon nanotubes show promise for use in flexible and high-speed nanoelectronics. Tube transistors: Researchers at the University of Illinois at Urbana Champaign have developed a technique to grow thousands of carbon nanotubes (shown in blue and white in this colorized scanning electron micrograph). The researchers deposit electrodes (shown in …

Dwave puts out a background summary of their Orion quantum computer

A Dwave system pdf that has questions and answers about their quantum computer and their quantum computer plans some more useful answers in the comments and discussion: “For the algorithms you demostrated, how many times do you have to run the quantum computer to get the right answer?” Generally the success rates are around 90% …

Light activated nanoscale scissors from Japan

Researchers in Japan have developed a pair of molecular-scale scissors that open and close in response to light. The tiny scissors are the first example of a molecular machine capable of mechanically manipulating molecules by using light, the scientists say.The scissors measure just three nanometers in length, small enough to deliver drugs into cells or …

Wealthy consumption, airplanes and the environment

Future pundit brought up a concern about high consumption by a lot of rich people in the future causing environmental problems I examine more of the statistics around the current situation. Previously I looked at what the projected wealth situation might look like. Work is being done to reduce the environmental impact of planes. Molecular …

Scientists Create First Non-Carbon Material with Near-Diamond Hardness

The material is a boron nitride “nanocomposite.” This means that, rather than consisting of one large continuous crystal, it is made of crystalline boron-nitride grains that are each a few to several nanometers in size. Although research groups have previously reported boron carbonitride materials, claimed to be the second and third hardest materials after diamond, …
