How an unfolding protein can induce programmed cell death

Eurekalert - Jul 06 2021 - 00:07
The death of cells is well regulated. If it occurs too much, it can cause degenerative diseases. Too little, and cells can become tumours. Mitochondria, the power plants of cells, play a role in this programmed cell death. Scientists from the University of Groningen (the Netherlands) and the University of Pittsburgh (U.S.) have obtained new insights in how mitochondria receive the signal to self-destruct. Their results were published in the Journal of Molecular Biology.

Studies add to concern about climate tipping

Eurekalert - Jul 06 2021 - 00:07
Two climate model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the climate system than anticipated.

Developing new techniques to build biomaterials

Eurekalert - Jul 06 2021 - 00:07
Scientists at the University of Leeds have developed an approach that could help in the design of a new generation of synthetic biomaterials made from proteins. The biomaterials could eventually have applications in joint repair or wound healing as well as other fields of healthcare and food production.

Study reveals source of remarkable memory of "superagers"

Eurekalert - Jul 06 2021 - 00:07
"Superagers" who performed a challenging memory task in an MRI scanner were able to learn and recall new information as well as 25-year-old participants. Neurons in the visual cortex of brains of superaging older adults retain their selective and efficient ability to process visual stimuli and create a distinct memory of the images. In the future, interventions to train specific areas of the brain to be more efficient may enable normal aging adults to enhance memory and other cognitive functions.

Relationship between chromosomal instability and senescence revealed in the fly Drosophila

Eurekalert - Jul 06 2021 - 00:07
Researchers at IRB Barcelona's Development and Growth Control lab have revealed the mechanisms by which cells enter senescence because of an imbalance in the number of chromosomes. Chromosomal instability is a common trait in most solid tumours, such as carcinoma, and fully understanding its relationship with cancer can help identify new therapeutic targets. The results have been published in the journal Developmental Cell.

Doctors warn against off-label use of new Alzheimer's drug for cerebral amyloid angiopathy

Eurekalert - Jul 06 2021 - 00:07
There is no clinical evidence that the monoclonal antibody aducanumab is beneficial to patients with cerebral amyloid angiopathy, according to a Massachusetts General Hospital neurologist and other officers with the International Cerebral Amyloid Angiography Association. In a letter in The Lancet Neurology, the group cited concerns over safety and efficacy in recommending that aducanumab not be prescribed off-label by physicians for the treatment of cerebral amyloid angiopathy.

Improved prediction of Indian Monsoon onset three months in advance using machine learning

Eurekalert - Jul 06 2021 - 00:07
The onset of the Indian summer monsoon has been predicted three months ahead for the last 40 years with the highest precision up until today. The result indicates longer seasonal forecasts based on machine learning may be a way to mitigate the consequences of an erratic monsoon system under future global warming.

High risk of divorce after TBI? Not necessarily, study suggests

Eurekalert - Jul 06 2021 - 00:07
Traumatic brain injury (TBI) has a major impact on the lives of affected patients and families. But it doesn't necessarily lead to an increased risk of marital instability, as two-thirds of patients with TBI are still married to the same partner 10 years after their injury, reports a study in the July/August issue of the Journal of Head Trauma Rehabilitation (JHTR). The official journal of the Brain Injury Association of America, JHTR is published in the Lippincott portfolio by Wolters Kluwer.

The evolution of vinegar flies is based on the variation of male sex pheromones

Eurekalert - Jul 06 2021 - 00:07
By analyzing the genomes of 99 species of vinegar flies and evaluating their chemical odor profiles and sexual behaviors, researchers at the Max Planck Institute for Chemical Ecology show that sex pheromones and the corresponding olfactory channels in the insect brain evolve rapidly and independently. The new study is a valuable basis for understanding how pheromone production, their perception and processing in the brain, and ultimately the resulting behavior drive the evolution of new species.

Satellite galaxies can carry on forming stars when they pass close to their parent galaxies

Eurekalert - Jul 06 2021 - 00:07
Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the larger galaxy would remove the gas from it, leaving it shorn of the material it would need to make new stars.

"All the lonely people": The impact of loneliness in old age on life and health expectancy

Eurekalert - Jul 06 2021 - 00:07
Lonely older adults live at least three fewer years and with poorer health, and being less active, than peers, say experts in ageing research in Singapore and Japan. The first to quantify the impact of loneliness on longevity and quality of life among seniors, the study highlights the problem of loneliness as populations age around the world and COVID-19 measures potentially exacerbate it.

Lipidomics research provides clues for drug resistance in schizophrenia

Eurekalert - Jul 06 2021 - 00:07
Researchers from Skoltech and the Mental Health Research Center have found 22 lipids in the blood plasma of people with schizophrenia that were associated with lower symptom improvement over time during treatment. The results show that different levels of symptom improvement are associated with different alterations in lipid levels. These can help track resistance to medication that affects over a third of patients and help further the understanding of the underlying mechanisms of disease manifestation and treatment response

New species of pseudo-horses living 37 million years ago

Eurekalert - Jul 06 2021 - 00:07
The UPV/EHU's Vertebrate Palaeontology research group has described two new species of palaeotheriidae mammals that inhabited the subtropical landscape of Zambrana (Álava) about 37 million years ago. Their atypical dental features could point to a difference in environmental conditions between the Iberian and Central European areas.
