This humidity digester breathes in atmospheric water and exhales energy

Integrating a super moisture-absorbent gel with light-active materials, researchers in Singapore have developed a humidity digester to dry the ambient air while generating energy. The method, presented November 20 in the journal Joule, is a green alternative to air conditioners with a trick – pulling water out of thin air. Like plants, artificial photosynthetic devices, also … Read more

Dog and sheep bones help injured pigeons fly again

Sheep and dog bones can be whittled into orthopedic pins that stabilize pigeons’ fractured wings, helping the fractures to heal properly without follow-up surgery. Researchers describe the treatment, which is cheaper and more efficient than using metal pins for pigeon rehabilitative surgeries, November 20th in the journal Heliyon. “There is no need for the implants to … Read more

Making tiny antennas for wearable electronics

When it comes to electronics, bigger usually isn’t better. This is especially true for a new generation of wearable communication systems that promise to connect people, machines and other objects in a wireless “internet of things.” To make the devices small and comfortable enough to wear, scientists need to miniaturize their components. Now, researchers in ACS … Read more

4D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4D imaging, which adds information on light polarization, could open up even more possibilities, but usually the equipment is bulky, expensive and complicated. Now, researchers reporting in ACS … Read more

The ever-changing brain: Shining a light on synaptic plasticity

Synapses – specialized structures in neurons – allow these nerve cells to communicate with one another. In the synapse, one neuron emits chemical messengers called neurotransmitters, and an apposed neuron receives them using tiny structures called receptors. A specific type of receptor, the AMPA receptor, plays a crucial role in learning and memory processes. However, … Read more

A decade after the predators have gone, Galapagos Island finches are still being spooked

On some of the Galapagos Islands where human-introduced predators of Darwin’s finches were eradicated over a decade ago, the finches are still acting as though they are in danger, according to research published today in the Journal of Animal Ecology. The study found that the finches’ fearful responses – known as antipredator behaviour – were sustained … Read more

A step in a new direction

Dr. Michael Fehlings, a Senior Scientist at the Krembil Research Institute, and his research team have discovered a network of nerve cells that plays a key role in controlling our ability to walk. The group’s findings, published in Nature Neuroscience, challenge conventional perceptions of how the brain instructs and regulates the body while walking. Although walking may … Read more

The first global geologic map of Titan completed

The first map showing the global geology of Saturn’s largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains. Titan is the only planetary body in our solar system other than Earth known to have stable liquid on its surface. But instead of water raining … Read more

Tiny filters help detect cancerous blood cells

Multiple myeloma is a type of blood cancer in which malignant plasma cells, a type of white blood cell, accumulate in the bone marrow. This leads to bone destruction and failure of the marrow, which in healthy individuals, produce all the body’s red blood cells. The most recent data from the American Cancer Society estimates … Read more

Malaria discovery could lead to better HIV and lupus treatments

A discovery about how the immune system responds to malaria infection could lead to better treatments for hepatitis C, HIV and lupus, say Australian researchers. The research team showed, in laboratory models, that strong inflammatory signals caused by malaria infection activate molecules that trigger the production of highly potent antibodies to fight the disease. The … Read more
