Mechanical stimuli significantly influence organ growth

Science Daily - 13/07/2021
In addition to chemical factors, mechanical influences play an important role in the natural growth of human organs such as kidneys, lungs and mammary glands - but also in the development of tumors. Now a research team has investigated the process in detail using organoids, three-dimensional model systems of such organs which are produced in the laboratory.

Electrons in quantum liquid gain energy from laser pulses

Science Daily - 13/07/2021
The absorption of energy from laser light by free electrons in a liquid has been demonstrated for the first time. Until now, this process was observed only in the gas phase. The findings open new doors for ultra-fast electron microscopy.

Global study reveals effectiveness of protected forests

Science Daily - 13/07/2021
Scientists have published a global study on the effectiveness of protected areas in preventing deforestation. The study explored the success of country-level protected areas at reducing forest loss, and used machine learning to uncover some of the factors that contribute to differences in effectiveness.

Simulating microswimmers in nematic fluids

Science Daily - 13/07/2021
New research shows how control over self-propelled microswimmers could be achieved using exotic materials named 'nematic liquid crystals' - whose viscosity and elasticity can vary depending on the direction of an applied force.

Mathematical model predicts the movement of microplastics in the ocean

Science Daily - 13/07/2021
New research has identified the processes that underpin the trajectories of microplastics below the ocean surface. The authors analyzed how biofouling -- the accumulation of algae on the surface of microplastics -- impacts the vertical movement of buoyant particles.

Reducing data-transfer error in radiation therapy

Science Daily - 13/07/2021
As the complexity of radiation therapy has grown, so too has the amount of data that goes into treatment machines. With more data comes more opportunity for errors in data transfer. A medical physics researcher is working to make those errors less likely.

The rat's whiskers: Multidisciplinary research reveals how we sense texture

Science Daily - 13/07/2021
Two very different teams of scientists have worked together to reveal important insights into how we sense texture by looking at the whiskers of a rat.

Combining plant-based diet and healthy microbiome may protect against multiple sclerosis

Science Daily - 13/07/2021
A new study shows that a diet rich in isoflavone, a phytoestrogen or plant-based compound that resembles estrogen, protects against multiple sclerosis-like symptoms in a mouse model of the disease. Importantly, the isoflavone diet was only protective when the mice had gut microbes capable of breaking down the isoflavones.

Question Corner | Do humans perceive joyful or fearful screams more strongly?

The Hindu:Science - 13/07/2021
 Most often, a human scream signals fear of imminent danger. But screaming can also express joy or excitement. For the first time, researchers Univers

Stopping illegal trade of Australian lizards

Science Daily - 13/07/2021
Australian reptiles face serious conservation threats from illegal poaching fueled by international demand and the exotic pet trade.

DNA reveals the evolutionary history of museum specimens

Science Daily - 13/07/2021
Museum specimens held in natural history collections around the world represent a wealth of underutilized genetic information due to the poor state of preservation of the DNA, which often makes it difficult to sequence. An international team has optimized a method developed for analyzing ancient DNA to identify the relationships between species on a deep evolutionary scale.

'Hydrogel-based flexible brain-machine interface'

Science Daily - 13/07/2021
A research team revealed a newly developed hydrogel-based flexible brain-machine interface.

Restless nights: Shelter housed dogs need days to adapt to new surroundings

Science Daily - 13/07/2021
Every year, thousands of dogs end up in a shelter in the Netherlands. Experts expect an increase in this number in the upcoming period, when people go back to the office after working from home during the corona crisis. Despite the good care of staff and volunteers, the shelter can be a turbulent experience for dogs. Researchers investigated if dogs can adapt to their new environment based on their nocturnal activity.

Revealing the mystery behind the threat of non-alcoholic liver disease

Science Daily - 13/07/2021
Researchers revealed how non-alcoholic fatty liver disease can develop into a life-threatening complication. Their discovery will accelerate the search for therapeutic solutions.

More complex than we thought: The body's reaction to contact allergens

Science Daily - 13/07/2021
Many people react to contact allergens, but some patients develop rashes and itching much faster than others. Previously the scientists were unable to explain why, but now researchers have outlined an entire new subgroup of allergic reactions which explains these early skin reactions. The new knowledge is vital to understanding the disease mechanisms in contact allergy.

Resilience, not collapse: What the Easter Island myth gets wrong

Science Daily - 13/07/2021
New research suggests that the demographic collapse at the core of the Easter Island myth didn't really happen.

A new approach to metastatic melanoma discovered

Science Daily - 13/07/2021
Combining chemotherapy with a BRAF oncogene inhibitor proves effective at treating this disease in a mouse model. This alternative paves the way toward a new approach for patients affected by this type of tumor, which has no cure in the most advanced stages or cases of relapse.

Dire impacts downstream of Nile River dam: Study

Science Daily - 13/07/2021
Downstream water supply and economic losses could substantially disrupt Egypt, according to a new analysis that offers potential solutions to avoid conflict over the dam.

COVID-19: Variants of Concern and Variants of Interest

The Hindu:Science - 13/07/2021
Which variants come under which category?

Crystal clear: Lepidopterans have many ways of being transparent

Science Daily - 13/07/2021
Breakthrough article reveals multiple mechanisms for wing transparency in butterflies and moths; shows that wing transparency has evolved multiple times in lepidopterans.
