Beyond good vibrations: New insights into metamaterial magic
Metamaterials have amazing potential--think invisibility cloaks and perfect lenses--but they are more likely to be found in a Harry Potter novel than a lab. To help bring them closer to reality, Michigan Technological University's Elena Semouchkina has gone back to basics and demonstrated that the fundamental physics of metamaterials is more complex than scientists once thought.

New research targets cancer's 'Achilles' Heel'
Northwestern Engineering's Vadim Backman has developed an effective new strategy for treating cancer that prevents cancer from evolving to withstand treatment, making the disease an easier target for existing drugs. If the cells cannot evolve to resist chemotherapy, for example, they die.

New UNC-Chapel Hill project aims to bring semantics to evolutionary trees
Researchers at the University of North Carolina at Chapel Hill will play key roles in a new project that applies semantic technologies developed by computer and information scientists to the field of evolutionary biology. The new project, funded by the National Science Foundation (NSF), aims to make this kind of expertise accessible to computers in a way that will open up new avenues for studying how phenotypes evolve along the tree of life.

Using powerful new telescope astronomers observe one of the oldest objects in the universe
Astronomers using the Large Millimeter Telescope (LMT), which is operated jointly by UMass Amherst and Mexico's Instituto Nacional de Astrofísica, Óptica y Electrónica, report today in Nature Astronomy that they have detected the second most distant dusty, star-forming galaxy ever found in the universe -- born in the first one billion years after the Big Bang. It is the oldest object ever detected by the LMT.

Researchers report first-ever protein hydrogels made in living cells
Johns Hopkins cell biologists report what they believe is the first-ever creation of tiny protein-based gelatin-like clumps called hydrogels inside living cells. The ability to create hydrogels on demand, they say, should advance the long scientific struggle to study the elusive structures -- which form in nature when proteins or other molecules aggregate under certain conditions -- and to uncover their suspected contributions to human diseases.

Tiny bees play big part in secret sex lives of trees
When it comes to sex between plants, tiny bees the size of ladybugs play a critical role in promoting long-distance pairings. That's what scientists at The University of Texas at Austin discovered after one of the most detailed paternity tests in wild trees ever conducted. The research gives new insights into how certain bees promote genetic diversity that is essential for plants to adapt to various threats, from disease to climate change.

Can environmental toxins disrupt the biological 'clock'?
Can environmental toxins disrupt circadian rhythms -- the biological 'clock' whose disturbance is linked to chronic inflammation and a host of human disorders? Research showing a link between circadian disruption and plankton that have adapted to road salt pollution puts the question squarely on the table.

Synthetic material acts like an insect cloaking device
Synthetic microspheres with nanoscale holes can absorb light from all directions across a wide range of frequencies, making them a candidate for antireflective coatings, according to a team of Penn State engineers. The synthetic spheres also explain how the leaf hopper insect uses similar particles to hide from predators in its environment.

Study shows need for adaptive powered knee prosthesis to assist amputees
New North Carolina State University research into wearable robotics shows how amputees wearing these devices adapted when presented with a real-world challenge: carrying a weighted backpack. The results could assist device manufacturers and clinicians expand the utility of these important devices, and could help researchers develop smarter controllers that adapt to real-world demands.

Newly discovered volcanic rock minerals may offer new insights into earth's evolution
Scientists have found evidence showing that komatiites, or three-billion-year old volcanic rock found within the Earth's mantle, had a different composition than modern ones. Their discovery may offer new information about the first one billion years of Earth's development and early origins of life. Results of the team's work has been published in the October 2017 edition of Nature Geoscience.

Penny-wise, pound-foolish decisions explained by neurons' firing
People sometimes spend as much time deciding whether to spend a few cents more on groceries as they do deciding whether to spend a few thousand dollars extra when buying a car. A new study from Washington University School of Medicine in St. Louis shows that these spending habits may reflect how our brains tally differences in value among objects that vary greatly in worth.

A strange new world of light
Structured beams of light, which exhibit strange behavior such as bending in a spiral, corkscrewing and dividing like a fork, not only can tell scientists a lot about the physics of light but also have a wide range of applications from super-resolution imaging to molecular manipulation and communications. Now, Harvard researchers have developed a tool to generate more complex structured light in a completely different way.

Electrostatic force takes charge in bioinspired polymers
Researchers at the University of Illinois and the University of Massachusetts, Amherst have taken the first steps toward gaining control over the self-assembly of synthetic materials in the same way that biology forms natural polymers. This advance could prove useful in designing new bioinspired, smart materials for applications ranging from drug delivery to sensing to remediation of environmental contaminants.

Scientists decipher mechanisms underlying the biology of aging
Scientists have helped decipher the dynamics that control how our cells age, and with it implications for extending human longevity. The group employed a combination of technologies to analyze molecular processes that influence aging. Using cutting-edge computational and experimental approaches the scientists discovered that a complete loss of chromatin silencing leads to accelerated cell aging and death. However, the researchers similarly found that continuous chromatin silencing also leads cells to a shortened lifespan.

Preventing a genetic uprising in early life
Around half of the human genome is made up of genetic parasites called transposons that can damage our genes, leading to a wide range of genetic illnesses. Normally they are controlled by chemical marks that shut down transposon activity, but there is a time early in life when this isn't possible. Research published in Cell Stem Cell from scientists at the Babraham Institute reveals how molecules called endosiRNAs keep transposons in check.
