An international team of researchers has discovered evidence of 27 previously unknown viruses in bees. The finding could help scientists design strategies to prevent the spread of viral pathogens among these important pollinators.
“Populations of bees around the world are declining, and viruses are known to contribute to these declines,” said David Galbraith, research scientist at Bristol Myers Squibb and a recent Penn State graduate. “Despite the importance of bees as pollinators of flowering plants in agricultural and natural landscapes and the importance of viruses to bee health, our understanding of bee viruses is surprisingly limited.”
To investigate viruses in bees, the team collected samples of DNA and RNA, which is responsible for the synthesis of proteins, from 12 bee species in nine countries across the world. Next, they developed a novel high-throughput sequencing technique that efficiently detected both previously identified and 27 never-seen-before viruses belonging to at least six new families in a single experiment. The results appear in the June 11, 2018, issue of Scientific Reports.
An interaction between aggregate alpha synuclein and ATP synthase implicated in Parkinson’s Disease.
An open-access paper published in Nature Communications sheds light on how an accumulation of α-synuclein protein in brain cells contributes to causing Parkinson’s disease. In particular, the researchers discovered how clumps of the protein damage important proteins on mitochondrial surfaces, leading to impaired energy production, swelling and bursting of the mitochondria themselves, and, ultimately, cell death [1].
Study abstract
It seems reasonable that people would want to maximize various aspects of life if they were given the opportunity to do so, whether it’s the pleasure they feel, how intelligent they are, or how much personal freedom they have. In actuality, people around the world seem to aspire for more moderate levels of these and other traits, according to findings published in Psychological Science, a journal of the Association for Psychological Science.
“Our research shows that people’s sense of perfection is surprisingly modest,” says psychological scientist Matthew J. Hornsey of the University of Queensland, first author on the research. “People wanted to have positive qualities, such as health and happiness, but not to the exclusion of other darker experiences—they wanted about 75% of a good thing.”
Furthermore, people said, on average, that they ideally wanted to live until they were 90 years old, which is only slightly higher than the current average life expectancy. Even when participants imagined that they could take a magic pill guaranteeing eternal youth, their ideal life expectancy increased by only a few decades, to a median of 120 years old. And when people were invited to choose their ideal IQ, the median score was about 130—a score that would classify someone as smart, but not a genius.

After the incredible success of the 2018 Undoing Aging Conference with 350 participants from 36 countries and over 40 brilliant speakers, SENS Research Foundation (SRF) and Forever Healthy Foundation (FHF) are pleased to announce that Undoing Aging 2019 will take place in Berlin at the Umspannwerk Alexanderplatz from March, 28 to 30.
The conference series Undoing Aging is focused on the cellular and molecular repair of age-related damage as the basis of therapies to bring aging under full medical control. Undoing Aging 2019 will once again bring together scientists from around the globe, all pioneers in their respective fields, who are leading the charge in maintaining and restoring full health in old age.
Some individuals worry they will discover things about their DNA that will be frightening — namely, the risks they run of contracting various diseases — and not know how to move forward with the information. Professional scientific skeptics contend the information may not even be as accurate as claimed, and lead people to make questionable health decisions. But there’s another type of risk that consumers aren’t focusing on as much, and it’s a big one: privacy. There is nothing more private than your personal genetic information, and sending away for a personal genome kit means sharing your DNA with the testing companies. What do they do with it, beyond providing consumers with genetic and health assessments?
Consumer DNA genetic testing kits are a booming business, and the biggest risk isn’t necessarily uncovering a health scare; it’s what these companies may do, or be forced to do, with your genetic data.
