Bees may feel pain

Posted by in categories: mathematics, neuroscience

We swat bees to avoid painful stings, but do they feel the pain we inflict? A new study suggests they do, a possible clue that they and other insects have sentienceโ€”the ability to be aware of their feelings.

โ€œItโ€™s an impressive piece of workโ€ with important implications, says Jonathan Birch, a philosopher and expert on animal sentience at the London School of Economics who was not involved with the paper. If the study holds up, he says, โ€œthe world contains far more sentient beings than we ever realized.โ€

Previous research has shown honey bees and bumble bees are intelligent, innovative, creatures. They understand the concept of zero, can do simple math, and distinguish among human faces (and probably bee faces, too). Theyโ€™re usually optimistic when successfully foraging, but can become depressed if momentarily trapped by a predatory spider. Even when a bee escapes a spider, โ€œher demeanor changes; for days after, sheโ€™s scared of every flower,โ€ says Lars Chittka, a cognitive scientist at Queen Mary University of London whose lab carried out that study as well as the new research. โ€œThey were experiencing an emotional state.โ€

New Research Reveals How Fear Get Stuck in Brains

Posted by in categories: biological, neuroscience

A biological mechanism has been identified by researchers at Linkรถping University in Sweden that increases the strength with which fear memories are stored in the brain The research, conducted in rats, was published in the scientific journal Molecular Psychiatry. It provides new insights into the processes behind anxiety-related disorders and identified shared mechanisms of anxiety and alcohol dependence.

The ability to feel fear is critical for escaping life-threatening circumstances and learning how to avoid them in the future. However, in certain conditions, such as post-traumatic stress disorder (PTSD

Post-traumatic stress disorder (PTSD) is a psychiatric disorder that develops in some people who have experienced or witnessed a shocking, scary, or dangerous event.

Pilot trial sees tumors shrink or disappear in 78% of patients

Posted by in categories: biotech/medical, neuroscience

The study brings much hope to patients with brain and spinal cord cancers.

A small pilot trial involving patients with lymphoma of the brain and/or spinal cord has shown that CAR-T-cell therapy known as axicabtagene ciloleucel (axi-cel) can be a viable treatment option for patients who often have little hope, according to a press release by Dana-Farber Cancer Institute investigators published on Sunday. โ€œFor many patients with lymphoma of the central nervous system, there arenโ€™t great treatment options,โ€ said Dana-Farberโ€™s Caron Jacobson, MD, MMSc, who led the trial.

Our early results suggest that expanding the applicability of CAR-T cells to this indication could improve patient outcomes.

Yale breakthrough may uncover the root cause of Alzheimerโ€™s

Posted by in categories: biotech/medical, neuroscience

The fight against Alzheimerโ€™s disease has been a tough one, but we are making progress. Not only have scientists created tech that can detect Alzheimerโ€™s in a single brain scan, but some research has also shown that repurposable drugs could help find a cure.

Gene expression data point to exercise as the most effective treatment for Alzheimerโ€™s disease

Posted by in categories: biotech/medical, health, neuroscience

An analysis of 22 large-scale gene expression datasets pointed to exercise and activity in general as the most effective theoretical treatment for reversing gene expressions typical of Alzheimerโ€™s disease. Fluoxetine, a well-known antidepressant, also showed effect, particularly when combined with exercise. Curcumin showed positive effects as well. The study was published in Scientific Reports.

Alzheimerโ€™s disease is a complex neurodegenerative disorder that affects multiple brain regions. It is the most common disease that causes dementia and is very difficult to treat. In the course of the disease, abnormal collections of proteins called tau accumulate inside neurons.

Another type of protein clumps together to form so-called amyloid plaques that collect between neurons and disrupt cell functions. These and other changes harm the functioning of the brain across different regions and lead to dysfunction and death of brain cells.

This nutrient supplement may actually boost memory function

Posted by in categories: biotech/medical, neuroscience

A recent study from Tokyo Medical and Dental University found that melatonin and two of its metabolites help memories stick around in the brain and can shield mice, and potentially people, from cognitive decline. One of the easiest ways to test memory in mice is to rely on their natural tendency to examine unfamiliar objects.

Harnessing the Brainโ€™s Immune Cells to Stave off Alzheimerโ€™s and Other Neurodegenerative Diseases

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers have identified a protein that could be leveraged to help microglia in the brain stave off Alzheimerโ€™s and other neurodegenerative diseases.

Source: The Conversation.

Many neurodegenerative diseases, or conditions that result from the loss of function or death of brain cells, remain largely untreatable. Most available treatments target just one of the multiple processes that can lead to neurodegeneration, which may not be effective in completely addressing disease symptoms or progress, if at all.
