Crossing a critical threshold in optical communications
Researchers from Lehigh University, Japan and Canada have advanced a step closer to the dream of all-optical data transmission by building and demonstrating what they call the 'world's first fully functioning single crystal waveguide in glass.' In an article published in Scientific Reports, the group said it had employed ultrafast femtosecond lasers to produce a three-dimensional single crystal capable of guiding light waves through glass with little loss of light.

California Academy of Sciences discovers 100 new species in the Philippines
Scientists from the California Academy of Sciences are celebrating World Ocean's Day with a slew of brand new marine discoveries -- more than 100 species that are likely new to science. Mysterious live animals from dimly-lit, deep-water reefs were also collected for a new exhibit at the Academy's Steinhart Aquarium, expected to open in the summer of 2016.

The shape of a perfect fire
In a study published in Nature Scientific Reports, Adrian Bejan of Duke University shows that, all other variables being equal, the best fires are roughly as tall as they are wide. This is why, he argues, everyone has built fires that basically look the same since the dawn of time, allowing humanity to master fire and migrate across the globe.

Diverse coral communities persist, but bioerosion escalates in Palau's low-pH waters
A new study led by scientists at Woods Hole Oceanographic Institution (WHOI) found that the coral reefs in Palau seem to be defying the odds, showing none of the predicted responses to low pH except for an increase in bioerosion -- the physical breakdown of coral skeletons by boring organisms such as mollusks and worms. The paper is published June 5 in the journal Science Advances.

Paleo-engineering: New study reveals complexity of Triceratops' teeth
When it comes to the three-horned dinosaur called the Triceratops, science is showing the ancient creatures might have been a little more complex than we thought. In fact, their teeth were far more intricate than any reptile or mammal living today.

Penn engineers show how 'perfect' materials begin to fail
Until recently, making a defect-free material was impossible. Now that nanotechnological advances have made such materials a reality, however, researchers at the University of Pennsylvania and Germany's Max Planck Institute for Intelligent Systems have shown how these defects first form on the road to failure.

New tropical tree species await discovery
Scientists raised the estimated number of tropical tree species to at least 40,000 to 53,000, the Smithsonian reports. Many tropical tree species risk extinction because of their rarity and restriction to small geographic areas, reaffirming the need for comprehensive, pan-tropical conservation efforts.

How dividing cells end up the same size
A new study from Duke University shows that how much a cell grows before it splits into two depends on its initial size. The finding goes against recent publications suggesting cells always add the same amount of mass, with some random fluctuations, before beginning division.

Comparative analyses of current three-dimensional numerical solar wind models
The world wide most advanced three-dimensional time-dependent numerical simulation solar wind models are assessed. These models can be classified into two categories: (1) theoretical, empirical and numerical based models and (2) self-consistent multi-dimensional numerical magnetohydrodynamic models.

Shh! Don't wake the sleeping virus!
Scientists at Bar-Ilan University report on a novel experimental model that, for the first time, successfully mimics the 'sleeping' and 'waking' of the varicella-zoster virus. Based on neurons generated from human embryonic stem cells, and not requiring the use of experimental animals, the model allows scientists to test drugs and develop therapies to prevent shingles. It may also contribute to the fight against other viruses -- such as herpes and polio -- that target the human nervous system.

Vanishing friction
Physicists at MIT have developed an experimental technique to simulate friction at the nanoscale. Using their technique, the researchers are able to directly observe individual atoms at the interface of two surfaces and manipulate their arrangement, tuning the amount of friction between the surfaces. By changing the spacing of atoms on one surface, they observed a point at which friction disappears.

Cheating amoebas reveal key to successful societies
Nobody likes a cheater. In a recent study, a University of Houston evolutionary biologist and her collaborators found that while cheaters do not take over populations, they also cannot ever fully be removed. Supported by grants from the National Science Foundation, the findings are described in a paper appearing June 15 in Current Biology.

Warmer, lower-oxygen oceans will shift marine habitats
Warming temperatures and decreasing levels of dissolved oxygen will act together to create metabolic stress for marine animals. Habitats will shift to places in the ocean where the oxygen supply can meet the animals' increasing future needs.

Planarian regeneration model discovered by artificial intelligence
An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria -- the small worms whose power to regrow body parts makes them a research model in human regenerative medicine. The discovery presents the first model of regeneration discovered by a non-human intelligence and the first comprehensive model of planarian regeneration, which has eluded human scientists for a century.

Sudden draining of glacial lakes explained
In 2008 scientists from Woods Hole Oceanographic Institution and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack open suddenly -- draining the lakes completely within hours and sending torrents of water to the base of the ice sheet thousands of feet below. Now they have found a surprising mechanism that triggers the cracks.

Paleo study shows how elevation may affect evolution
About 34 million years ago, global temperatures took a dive, causing a sudden wave of extinctions among European mammals. In North America, however, life went on largely unscathed. A new study explains why: the rise of the Rocky Mountains had forced North American mammals to adapt to a colder, drier world.

Trouble in the tide pools
A harmful algal bloom is the suspected culprit of a die-off in 2011 of millions of purple sea urchins and six-starred sea stars in Northern California. Their disappearance is predicted to have long-term ecological consequences on their populations. As algal blooms are expected to increase with climate change and ocean acidification, similar mass mortality events are expected to increase.
