Nanocontainer ships titan-size gene therapies and drugs into cells — ScienceDaily

Scientists at Johns Hopkins Medicine report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size — even hefty ones attached to the gene-editing tool called CRISPR. If their creation — constructed of a biodegradable polymer — passes more laboratory testing, it could offer a way to efficiently ferry larger medical compounds into specifically selected target cells. A report on their work appears in the Dec. 6 issue…

Gulf of Mexico coral reefs to protect from storm surge in the future — But will they? — ScienceDaily

Coral reefs support 25 percent of all marine life around the globe. Those in the Gulf of Mexico, along the coasts of Louisiana, Florida, Texas and Mexico, might be less known and less popular among tourists than other reefs; nevertheless, they also serve as important barriers to storm surge, lessening the impact of dangerous hurricanes. In a new paper published in the journal Frontiers in Marine Science, LSU geography and anthropology professor Kristine DeLong and her team of researchers used…

Making higher-energy light to fight cancer — ScienceDaily

Materials scientists at the University of California, Riverside and The University of Texas at Austin have demonstrated that it is possible to achieve photon up-conversion, the emission of light with energy higher than the one that excites the material, when using carefully designed structures containing silicon nanocrystals and specialized organic molecules. The accomplishment, published in Nature Chemistry, brings scientists one step closer to developing minimally invasive photodynamic treatments for cancer. The advance could also hasten new technologies for solar-energy conversion,…

With ultracold chemistry, researchers get first look at exactly what happens during a chemical reaction — ScienceDaily

The coldest chemical reaction in the known universe took place in what appears to be a chaotic mess of lasers. The appearance deceives: Deep within that painstakingly organized chaos, in temperatures millions of times colder than interstellar space, Kang-Kuen Ni achieved a feat of precision. Forcing two ultracold molecules to meet and react, she broke and formed the coldest bonds in the history of molecular couplings. “Probably in the next couple of years, we are the only lab that can…

Ostrich eggshell beads reveal 10,000 years of cultural interaction across Africa — ScienceDaily

Ostrich eggshell beads are some of the oldest ornaments made by humankind, and they can be found dating back at least 50,000 years in Africa. Previous research in southern Africa has shown that the beads increase in size about 2,000 years ago, when herding populations first enter the region. In the current study, researchers Jennifer Miller and Elizabeth Sawchuk investigate this idea using increased data and evaluate the hypothesis in a new region where it has never before been tested.…

New material should be relatively easy to produce at an industrial scale, researchers say — ScienceDaily

MIT researchers have improved on a transparent, conductive coating material, producing a tenfold gain in its electrical conductivity. When incorporated into a type of high-efficiency solar cell, the material increased the cell’s efficiency and stability. The new findings are reported in the journal Science Advances, in a paper by MIT postdoc Meysam Heydari Gharahcheshmeh, professors Karen Gleason and Jing Kong, and three others. “The goal is to find a material that is electrically conductive as well as transparent,” Gleason explains,…

Foam offers way to manipulate light — ScienceDaily

There is more to foam than meets the eye. Literally. A study by Princeton scientists has shown that a type of foam long studied by scientists is able to block particular wavelengths of light, a coveted property for next-generation information technology that uses light instead of electricity. The researchers, integrating expertise from materials science, chemistry and physics, conducted exhaustive computational simulations of a structure known as a Weaire-Phelan foam. They found that this foam would allow some frequencies of light…

The road less traveled — ScienceDaily

Two pathways diverged in a chemical synthesis, and one molecule took them both. Chemists at the University of Tokyo have studied how molecular building blocks can either form a spherical cage or an ultrathin sheet that shows some of the basic properties of a “smart” material that can respond to its environment. “This molecule is interesting because it builds different structures depending on the conditions when it reaches the bifurcation point of its synthesis,” said Professor Shuichi Hiraoka from the…

How nematodes outsmart the defenses of pests — ScienceDaily

The western corn rootworm causes economic losses of over 2 billion US dollars in maize cultivation and is thus a serious agricultural pest. Originally from America, the western corn rootworm is currently invading Europe, including Switzerland. A successful pest In an earlier study, Christelle Robert and Matthias Erb from the Institute of plant sciences (IPS) at the University of Bern elucidated one of the strategies that underlies the success of the western corn rootworm. Maize plants store certain defense substances,…

Is Vitamin E Acetate Killing Vapers?

Officials at the U. S. Centers for Disease Control announced Friday that they may have found a cause for the lung injuries and deaths in people who use e-cigarettes.  Since the problem arose last March, a total of 39 people have died from what is now being called “e-cigarette, or vaping, product use associated lung injury,” (EVALI for short) and over 2,000 more have become ill or hospitalized.  A report by National Public Radio says that a compound called vitamin…
