Huge prehistoric croc 'river boss' prowled waterways

Science Daily - 14/06/2021
A new species of large prehistoric croc that roamed southeast Queensland's waterways millions of years ago has been documented.

Brain capillary structures show a correlation with their neuron structures

Science Daily - 14/06/2021
Researchers performed microtomography experiments the BL20XU beamline of the SPring-8 synchrotron radiation facility and found that brain capillary structures show a correlation with their neuron structures.

Stents inspired by paper-cutting art can deliver drugs to the GI tract

Science Daily - 14/06/2021
Inspired by kirigami, the Japanese art of folding and cutting paper, engineers have designed a new type of stent that could be used to deliver drugs to the gastrointestinal tract, respiratory tract, or other tubular organs in the body.

Touchless technology could enable early detection and treatment of eye diseases that cause blindness

Science Daily - 14/06/2021
A new non-contact laser imaging system developed by engineering researchers, is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.

Potential new treatment target for Alzheimer's disease

Science Daily - 14/06/2021
A new study not only sheds light on how the APOE4 gene may cause some of the pathologies associated with Alzheimer's disease, but also suggests a new treatment target that might help people who carry the APOE4 gene in early and late stages of the disease. Researchers found that APOE4 is associated with the activation of an inflammatory protein that causes a breakdown in the blood-brain barrier which protects the brain.

A new model of Alzheimer's progression

Science Daily - 14/06/2021
Scientists explore how protein and signaling pathways change in patients with Alzheimer's disease. Their work creates a new model of disease progression, taking advantage of the heterogeneity that is inherent to human studies.

One step towards a daily-use deep UV light source for sterilization and disinfection

Science Daily - 14/06/2021
Researchers invented a more efficient device for doubling the frequency of incoming light by combining period reflectors inside a microcavity containing gallium nitride. This work may help in the construction of a deep UV light source with bactericidal effect that is both safe and practical.

Too many forewing eyespots are bad for butterflies

Science Daily - 14/06/2021
Biologists sought to understand the impact of uneven distribution of eyespots on butterflies. The team found that the location of these eyespots is key to their protective function.

Hair follicles heal blisters at personal cost

Science Daily - 14/06/2021
A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process.

Easy, inexpensive, efficient: Researchers improve efficacy of new malaria drug

Science Daily - 14/06/2021
Artemisone is a promising substance in the fight against malaria. However, the active ingredient has yet to be used due its instability and because it is not easily absorbed by the body. A team has now pushed this a bit further. They have developed a very simple method for preparing the active ingredient that makes it easier to administer and store.

Irish potato famine pathogen stoked outbreaks on six continents

Science Daily - 14/06/2021
Researchers tracking the evolution of different strains of the plant pathogen that caused the Irish potato famine in the 1840s show that the historic lineage called FAM-1 was found in nearly three-fourths of the 140 historic and modern samples tested and was found on all six continents.

The sun's clock

Science Daily - 14/06/2021
Not only the 11-year cycle, but also all other periodic solar activity fluctuations can be clocked by planetary attractive forces. With new model calculations, they are proposing a comprehensive explanation of known sun cycles for the first time. They also reveal the longest fluctuations in activity over thousands of years as a chaotic process.

Black holes help with star birth

Science Daily - 14/06/2021
The cosmic mass monsters clear the way for the formation of new suns in satellite galaxies.

Earliest memories can start from the age of two-and-a-half

Science Daily - 14/06/2021
On average the earliest memories that people can recall point back to when they were just two-and-a-half years old, a new study suggests.

From milk protein, a plastic foam that gets better in a tough environment

Science Daily - 14/06/2021
A new high-performance plastic foam developed from whey proteins can withstand extreme heat better than many common thermoplastics made from petroleum. A research team reports that the material, which may be used for example in catalysts for cars, fuel filters or packaging foam, actually improves its mechanical performance after days of exposure to high temperatures.

Engineers devise novel approach to wirelessly power wearable devices

Science Daily - 14/06/2021
Researchers have come up with a way to use one single device - such as a mobile phone or smart watch - to wirelessly power up to 10 wearables on a user. This novel method uses the human body as a medium for transmitting power. Their system can also harvest unused energy from electronics in a typical home or office environment to power the wearables.

New glial cells discovered in the brain: Implications for brain repair

Science Daily - 14/06/2021
Neurons, nerve cells in the brain, are central players in brain function. However, a key role for glia, long considered support cells, is emerging. A research group has now discovered two new types of glial cells in the brain, by unleashing adult stem cells from their quiescent state. These new types of glia may play an important role in brain plasticity and repair.

Key cause of energy loss in spintronic materials

Science Daily - 14/06/2021
A study uncovered a property of magnetic materials that will allow engineers to develop more efficient spintronic devices in the future, which could lead to faster and more efficient computing and data storage.

Plant-based diet protects from hypertension, preeclampsia

Science Daily - 14/06/2021
A plant-based diet appears to afford significant protection to rats bred to become hypertensive on a high-salt diet, scientists report. When the rats become pregnant, the whole grain diet also protects the mothers and their offspring from deadly preeclampsia.
