Revolutionizing hydrogen production: Economical and efficient solutions unveiled

23/03/2024
Scientists introduce superaerophobic three-dimensional nickel nanostructured catalysts for accelerated water electrolysis.

Natural recycling at the origin of life

23/03/2024
How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in their sequences, these biomolecules need to release water. On the early Earth, which was largely covered in seawater, that was not so easy to do.

Bees need food up to a month earlier than provided by recommended pollinator plants

23/03/2024
Plant species which are recommended as 'pollinator friendly' in Europe begin flowering up to a month too late for bees, resulting in low colony survival and low production of queens. This research has quantified the decline in colony survival and queen production due to a shortage of early season food. Enhancing existing hedgerows with early blooming species has the potential to increase the probability that a bee colony survives from 35% to 100%.

All countries' agri-environmental policies at a glance

23/03/2024
There can be no analysis without data. In this spirit, researchers have published a database containing over 6,000 agri-environmental policies, thus enabling their peers as well as policymakers and businesses to seek answers to all manner of different questions. The researchers have used two examples to demonstrate how this can be done: how a country's economic development is linked to its adoption of agri-environmental policies and how such policies impact soil erosion.

The aging brain: Protein mapping furnishes new insights

23/03/2024
For the neurons in the brain to work smoothly and be able to process information, the central nervous system needs a strictly regulated environment. This is maintained by the blood-brain barrier, whereby specialized brain endothelial cells lining the inner walls of blood vessels regulate the exchange of molecules between the circulatory and nervous systems. Earlier studies have shown that various functions that are dependent on these cells, such as the integrity of the blood-brain barrier or the regulation of blood supply to the brain, decline over the course of a person's life. This dysregulation leads to a dysfunction of the brain vasculature and is therefore a major contributor to medical conditions such as strokes and dementia.

Downscaling storage devices: Magnetic memory based on the chirality of spiral magnets

23/03/2024
A team of researchers has proposed a new concept for magnet-based memory devices, which might revolutionize information storage devices owing to their potential for large-scale integration, non-volatility, and high durability.

Physicists develop modeling software to diagnose serious diseases

23/03/2024
Researchers have recently published FreeDTS -- a shared software package designed to model and study biological membranes at the mesoscale -- the scale 'in between' the larger macro level and smaller micro level. This software fills an important missing software among the available biomolecular modeling tools and enables modeling and understanding of many different biological processes involving the cellular membranes e.g. cell division.

Enormous ice loss from Greenland glacier

23/03/2024
Ground-based measuring devices and aircraft radar operated in the far northeast of Greenland show how much ice the 79 N-Glacier is losing. According to recent measurements, the thickness of the glacier has decreased by more than 160 meters since 1998. Warm ocean water flowing under the glacier tongue is melting the ice from below. High air temperatures cause lakes to form on the surface, whose water flows through huge channels in the ice into the ocean. One channel reached a height of 500 meters, while the ice above was only 190 meters thick.

Multiple unsafe sleep practices found in most sudden infant deaths

23/03/2024
More than three-quarters of Sudden Unexpected Infant Deaths analyzed in a new study featured multiple unsafe sleep practices. The researchers are urging care providers to take a more active role in educating new parents on safe-sleep practices and helping implement them.

Scientists close in on TB blood test which could detect millions of silent spreaders

23/03/2024
Millions of people are spreading tuberculosis unknowingly - now scientists say they are close to developing a new test that is as simple as the lateral flows used during the Covid pandemic.

An avocado a day may improve overall diet quality, researchers report

23/03/2024
Eating one avocado per day may improve overall diet quality. A recent study found that the participants who had an avocado per day significantly increased their adherence to dietary guidelines.

Researchers describe tools to better understand CaMKII, a protein involved in brain and heart disease

23/03/2024
The health impacts of a complex protein that plays a major role in the development of Alzheimer's disease and heart conditions can be lessened by three kinds of drug inhibitors, according to scientists.

Scientists uncover evidence that microplastics are contaminating archaeological remains

23/03/2024
A team of archaeologists discovered tiny microplastic particles in deposits located more than seven meters deep, in samples dating back to the first or early second century and excavated in the late 1980s.

Your dog understands that some words 'stand for' objects

23/03/2024
It's no surprise that your dog can learn to sit when you say 'sit' and come when called. But a new study has made the unexpected discovery that dogs generally also know that certain words 'stand for' certain objects. When dogs hear those words, brain activity recordings suggest they activate a matching mental representation in their minds.

Movement disorder ALS and cognitive disorder FTLD show strong molecular overlaps, new study shows

23/03/2024
Single-cell gene expression patterns in the brain motor and frontal cortex, and evidence from follow-up experiments, reveal many shared cellular and molecular similarities that could be targeted for potential treatment.

Most new doctors face some form of sexual harassment, even after #MeToo

23/03/2024
More than half of all new doctors face some form of sexual harassment in their first year on the job, including nearly three-quarters of all new female doctors and a third of males, a new study finds. That's actually down somewhat from the percentage of new doctors who experienced the same five or six years before.

Researchers propose a new way to identify when babies become conscious

23/03/2024
Academics are proposing a new and improved way to help researchers discover when consciousness emerges in human infancy.

New way to find proteins for targeted treatment of disease

23/03/2024
Researchers have created a new platform to identify proteins that can be co-opted to control the stability of other proteins -- a new but largely unrealized approach to the treatment of disease.

Researchers invent artificial intelligence model to design new superbug-fighting antibiotics

23/03/2024
Researchers at McMaster University and Stanford University have invented a new generative artificial intelligence model which can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory.

Early intervention after the first seizure may prevent long-term epilepsy and associated cognitive deficits

23/03/2024
Only a very small percentage of neurons show changes after an epileptic seizure in mice, but these alterations can be permanent and trigger future seizures. An experimental treatment may prevent these long-term changes.
