A potential COVID-19 vaccine, delivered by microscopic needles, produces antibodies specific to the virus when tested in mice. This is the first peer-reviewed paper describing a COVID-19 vaccine candidate. The next step is a human clinical trial.

Whooping cranes form larger flocks as wetlands are lost -- and it may put them at risk
Posted on Thursday April 02, 2020

Over the past few decades, the endangered whooping crane (Grus Americana) has experienced considerable recovery. However, researchers found that habitat loss has led whooping cranes to gather in unusually large groups during migration. While larger groups are a positive sign of species recovery, the authors say that a disease outbreak or extreme weather event could inadvertently impact this still fragile population.

Our oceans are suffering, but we can rebuild marine life
Posted on Thursday April 02, 2020

It's not too late to rescue global marine life, according to a study outlining the steps needed for marine ecosystems to recover from damage by 2050. The study found many components of marine ecosystems could be rebuilt if we try harder to address the causes of their decline.

Discovery of life in solid rock deep beneath sea may inspire new search for life on Mars
Posted on Thursday April 02, 2020

Newly discovered single-celled creatures living deep beneath the seafloor have provided clues about how to find life on Mars. These bacteria were discovered living in tiny cracks inside volcanic rocks after researchers perfected a new method cutting rocks into ultrathin slices to study under a microscope. Researchers estimate that the rock cracks are home to a community of bacteria as dense as that of the human gut, about 10 billion bacterial cells per cubic centimeter.

Understanding how the protein tau moves between neurons yields insight into possible treatments for neurodegenerative diseases
Posted on Wednesday April 01, 2020

In the fight against neurodegenerative diseases such as frontotemporal dementia, Alzheimer's and Chronic Traumatic Encephalopathy, the tau protein is a major culprit. Found abundantly in our brain cells, tau is normally a team player -- it maintains structure and stability within neurons, and it helps with transport of nutrients from one part of the cell to another.

Understanding brain tumors in children
Posted on Wednesday April 01, 2020

The causes of 40% of all cases of certain medulloblastomas -- dangerous brain tumors affecting children -- are hereditary. A genetic defect that occurs in 15% of these children plays a key role by destabilizing the production of proteins. The researchers suspect that protein metabolism defects could be a previously underestimated cause of other types of cancer.

Most of Earth's carbon was hidden in the core during its formative years
Posted on Wednesday April 01, 2020

Carbon is essential for life as we know it and plays a vital role in many of our planet's geologic processes -- not to mention the impact that carbon released by human activity has on the planet's atmosphere and oceans. Despite this, the total amount of carbon on Earth remains a mystery, because much of it remains inaccessible in the planet's depths.

Smartphone videos produce highly realistic 3D face reconstructions
Posted on Wednesday April 01, 2020

Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone's face. Now, researchers have pulled off the feat using video recorded on an ordinary smartphone. Shooting a continuous video of the front and sides of the face generates a dense cloud of data. A two-step process uses that data, with some help from deep learning algorithms, to build a digital reconstruction of the face.
