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.

Research uncovers a rare resin fossil find: A spider that aspires to be an ant

23/03/2024
Spiders that disguise themselves as ants live in many locations around the globe but until now most had been able to avoid detection from fossil researchers as well as predators.

Signs of life would be detectable in single ice grain emitted from extraterrestrial moons

23/03/2024
Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

Tudor era horse cemetery in Westminster revealed as likely resting place for elite imported animals

23/03/2024
Archaeological analysis of a near unique animal cemetery discovered in London nearly 30 years ago has revealed there was an international horse trading network, orchestrated by the elites of late medieval and Tudor England, which brought superior physical specimens to the UK for jousting and for use as status symbols.

Two of the Milky Way's earliest building blocks identified

22/03/2024
Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city.

Two keys needed to crack three locks for better engineered blood vessels

22/03/2024
Biomedical researchers discovered two proteins that differentiate stem cells into the components of blood vessels. This finding has implications for drug testing and other clinical applications.

Product that kills agricultural pests also deadly to native Pacific Northwest snail

22/03/2024
A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.

An immunotherapy to overcome resistant leukemia

22/03/2024
Researchers have discovered that a specific mutation in the cancer cells of an aggressive type of blood cancer can prevent novel immunotherapies such as CAR T-cell therapy from working. Their study also explains why the cancer cells are resistant and how this resistance can be overcome: through concomitant pharmacotherapy or genetically improved CAR T-cells.

Evolutionary history of the formation of forceps and maternal care in earwigs

22/03/2024
Researchers examined the developmental processes and reproduction-related behavior of 8 of the 11 families of Dermaptera (earwigs) in detail and compared with those reported in previous studies. The results confirmed that Dermaptera is a polyneopteran order, and the features such as caudal forceps and elaborate maternal care for eggs and young larvae emerged in parallel within the order during evolution.

High-resolution brain created with 3D printer

22/03/2024
A 3D-printed 'brain phantom' has been developed, which is modeled on the structure of brain fibers and can be imaged using a special variant of magnetic resonance imaging (dMRI). The scientific team has now shown in a study, these brain models can be used to advance research into neurodegenerative diseases such as Alzheimer's, Parkinson's and multiple sclerosis.

Say hello to biodegradable microplastics

22/03/2024
Finding viable alternatives to traditional petroleum-based plastics and microplastics has never been more important. New research shows that their plant-based polymers biodegrade -- even at the microplastic level -- in under seven months.

Rays were more diverse 150 million years ago than previously thought

22/03/2024
Scientists have explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity -- including a new ray species. This study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.

Rose essential oil: A safe pesticide for organic agriculture

22/03/2024
Following injury, plants release terpenoids to enhance their defenses. Researchers studying terpenoid-enriched essential oils (EOs) have found that rose EO (REO) can stimulate defense genes in tomato leaves. Furthermore, REO attracts herbivores that protect the plant from the moth species, Spodoptera litura, and Tetranychus urticae, a mite pest. This suggests that applying REO could be a sustainable approach to pest management in organic farming.

The power of neighbors: Neighboring synapses shape learning and memory

22/03/2024
A researcher has developed a new model that provides a holistic view on how our brain manages to learn quickly and forms stable, long-lasting memories. Their study sheds light on the crucial role of interactions among neighboring contact sites of nerve cells for brain plasticity -- the brain's ability to adapt to new experiences.
