New research reveals plant wonderland inside China’s caves
New research reveals plant wonderland inside chinas caves
Exciting new data on cave flora has been published today in PLOS ONE in a paper by researchers from the Royal Botanic Gardens, Kew and the Guangxi Institute of Botany in China. Over five years (2009-2014) the researchers delved into the depths of some of China’s most unexplored and unknown caves in the largest ever study on ... sciencebulletin.org/archive...

Cancer-fighting nanorobots programmed to seek and destroy tumors
Cancer fighting nanorobots programmed to seek and destroy tumors
In a major advancement in nanomedicine, Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences, have successfully programmed nanorobots to shrink tumors by cutting off their blood supply. “We have developed the first fully autonomous, DNA robotic system for a ... sciencebulletin.org/archive...

No glaciers, no water?
No glaciers no water
The world’s largest rivers begin in glaciated mountain regions. However, climate change may cause many glaciers to disappear. Will water become scarce? There are around 200,000 glaciers worldwide. They play a central role in the water cycle, particularly in the middle and low latitudes, by offsetting runoff fluctuations. Rivers are lifelines on which billions of ... sciencebulletin.org/archive...

Birds and beans: Study shows best coffee for bird diversity
Birds and beans study shows best coffee for bird diversity
It’s an age-old debate for coffee lovers. Which is better: Arabica beans with their sweeter, softer taste, or the bold, deep flavor of Robusta beans? A new study by WCS, Princeton University, and the University of Wisconsin-Madison appearing in the journal Scientific Reports has taken the question to unlikely coffee aficionados: birds. The researchers, led by WCS ... sciencebulletin.org/archive...

Researchers create DNA wires 100 times more sensitive than other biosensors
Researchers create dna wires 100 times more sensitive than other biosensors
Scientists in Sweden reported a nanoengineering innovation that offers hope for treatment of cancer, infections and other health problems – conductive wires of DNA enhanced with gold which could be used to electrically measure hundreds of biological processes simultaneously. While DNA nanowires have been in development for some time, the method developed at KTH Royal ... sciencebulletin.org/archive...

New Horizons captures record-breaking images in the Kuiper Belt
New horizons captures record breaking images in the kuiper belt
NASA’s New Horizons spacecraft recently turned its telescopic camera toward a field of stars, snapped an image – and made history. The routine calibration frame of the “Wishing Well” galactic open star cluster, made by the Long Range Reconnaissance Imager (LORRI) on Dec. 5, was taken when New Horizons was 3.79 billion miles (6.12 billion ... sciencebulletin.org/archive...

Can a cockroach teach a robot how to scurry across rugged terrain?
Can a cockroach teach a robot how to scurry across rugged terrain
When they turn up in family pantries or restaurant kitchens, cockroaches are commonly despised as ugly, unhealthy pests and are quickly killed. But in the name of science, Johns Hopkins researchers have put these unwanted bugs to work. In a crowded, windowless lab, scholars and students are coaxing the insects to share some crucial locomotion ... sciencebulletin.org/archive...

Intercellular communication system is found to encode and transmit more messages than previously thought
Intercellular communication system is found to encode and transmit more messages than previously thought
Multicellular organisms like ourselves depend on a constant flow of information between cells, coordinating their activities in order to proliferate and differentiate. Deciphering the language of intercellular communication has long been a central challenge in biology. Now, Caltech scientists have discovered that cells have evolved a way to transmit more messages through a single pathway, ... sciencebulletin.org/archive...

Metasurfaces enable improved optical lens performance
Metasurfaces enable improved optical lens performance
Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now Penn State engineers have developed a new theory that solves the problem using a single thin lens comprised of gradient index materials and metasurface layers to properly direct the light. ... sciencebulletin.org/archive...

Study maps molecular mechanisms crucial for new approach to heart disease therapy
Study maps molecular mechanisms crucial for new approach to heart disease therapy
Creating new healthy heart muscle cells within a patient’s own ailing heart. This is how scientists hope to reverse heart disease one day. Today, a new study led by UNC-Chapel Hill researchers reveals key molecular details that should be useful in developing this ambitious approach. In this study, published in Cell Reports, two labs at UNC ... sciencebulletin.org/archive...
