Great Barrier Reef almost drowned; climate implications
The first comprehensive analysis of the Great Barrier Reef at a time of rapid sea-level rise during the beginning of the Last Interglacial found it almost died. The Ph.D. research shows the reef can be resilient but questions remain about cumulative impacts. The research also provides an accurate identification of the age of the fossil reef that grew before the modern Great Barrier Reef, some 129,000-121,000 years ago.

Measuring trees with the speed of sound
Foresters and researchers are using sound to look inside living trees. A new study in Applications in Plant Sciences presents methods for use of sonic tomography, which measures wood decay by sending sound waves through tree trunks. The new study describes optimum placement of the sensors to avoid aberrant tomography results for the non-model tree shapes that populate the tropics and details how to analyze the tomograms to quantify areas of decayed and damaged wood.

Density functional theory took a wrong turn recently
A new study by scientists from A.N. Nesmeyanov Institute of Organoelement Compounds, Moscow, Russia, and Temple University, Philadelphia, Pa., USA shows that the density functional theory, the bread and butter of modern computational chemistry, has significantly deviated in the recent years from the theoretical foundations it was built upon. The results were published in Science.

South American fossil tomatillos show nightshades evolved earlier than thought
Delicate fossil remains of tomatillos found in Patagonia, Argentina, show that this branch of the economically important family that also includes potatoes, peppers, tobacco, petunias and tomatoes existed 52 million years ago, long before the dates previously ascribed to these species, according to an international team of scientists.

Study finds potential instability in Atlantic Ocean water circulation system
One of the world's largest ocean circulation systems may not be as stable as today's weather models predict, according to a new study. In fact, changes in the Atlantic Meridional Overturning Circulation -- the same deep-water ocean current featured in the movie 'The Day After Tomorrow' -- could occur quite abruptly, in geologic terms, the study says.

New technique uses immune cells to deliver anti-cancer drugs
Some researchers are working to discover new, safer ways to deliver cancer-fighting drugs to tumors without damaging healthy cells. Others are finding ways to boost the body's own immune system to attack cancer cells. Researchers at Penn State have combined the two approaches by taking biodegradable polymer nanoparticles encapsulated with cancer-fighting drugs and incorporating them into immune cells to create a smart, targeted system to attack cancers of specific types.

Fast radio burst tied to distant dwarf galaxy, and perhaps magnetar
Since first detected 10 years ago, fast radio bursts have puzzled astronomers. Unlike pulsars, they flash irregularly, most only once, and only for milliseconds. And they seem to come from outside the galaxy, meaning they are very energetic. A team of astronomers has now localized the only repeating burst, to a distant dwarf galaxy. UC Berkeley's Casey Law, who created the rapid data collection and analysis software on the VLA, sees a connection to magnetars.
