Older people appear to be especially good at remembering things that interest them

by BPS Research Digest in BPS Research Digest

Our memory abilities begin to diminish in some respects as early as our twenties. But the picture isn't entirely bleak. A new study published in Psychology and Aging explores the possibility that an older person's curiosity or interest in a subject can reinforce their powers of memory. Following this view, old age is associated with forgetting more of what you don't care about, but the ability to remember what matters to you is preserved or even enhanced.Shannon McGillivray and her colleagues te........

Recurrent antibiotic exposure and risk of depression and/or anxiety?

by Paul Whiteley in Questioning Answers

Accepting the notions that (i) correlation is not necessarily the same as causation and that (ii) case-control observational studies in particular are not the best way to ascertain whether A causes B, I was rather interested in the findings reported by Ido Lurie and colleagues [1] and that: "Recurrent antibiotic exposure is associated with increased risk for depression and anxiety but not for psychosis."Starting from the idea that: "Changes in the microbiota (dysbiosis) were sugge........

Lighting up Leptospira interrogans to test antibiotic treatment of chronically-infected mice

by Microbe Fan in Spirochetes Unwound

A group at the Pasteur Institute succeeded in generating a bioluminescent strain of Leptospira interrogans.  Their study was published last year in PLOS Neglected Tropical Diseases.The benefit of having a bioluminescent strain is that infections of small laboratory rodents can be monitored without sacrificing the animals.  Instead, the animals are placed in a special whole-body imager that detects light emitted from the bodies.  The location of the infection in the animals can be ........

A protein-RNA structure hints at how viruses commandeer human proteins

by Dr. Jekyll in Lunatic Laboratories

Researchers at Case Western Reserve University and the University of Michigan have produced the first image of an important human protein as it binds with ribonucleic acid (RNA), a discovery that could offer clues to how some viruses, including HIV, control expression of their genetic material. That information could lead to new strategies to block viruses from replicating, thereby limiting or halting infection.... Read more »

A New Boost for Cancer Stem Cell Therapies

by Rita dos Santos Silva in United Academics

Patent for Bozepinib approved by scientists of University of Granada

Researchers at the University of Granada, Spain, have patented Bozepinib, a drug that inhibits the growth of cancer stem cells in breast, colon and melanoma cancers.

The mechanisms of action of Bozepinib were first described in an article published in the Open Access journal Oncotarget back in 2014. The team showed that Bozepinib was able to inhibit growth and metastasis of tumors in mice without inducing toxicity. Follow........ Read more »

Monkeys Keep Their Food Clean, Sort Of

by Elizabeth Preston in Inkfish

We all have our standards. For humans, it's the five-second rule. For macaques, it's "think twice before eating food off a pile of poop." The monkeys have several ways of keeping their food (sort of) clean. And the most fastidious macaques, it seems, are rewarded with fewer parasites.

On the Japanese island of Koshima, scientists have been studying Japanese macaques (Macaca fuscata) for nearly seven decades. The tiny, forested island is overrun with the monkeys, which live there naturally... Read more »

Comparing Obama's and Romney's speech styles and the way their audiences react

by BPS Research Digest in BPS Research Digest

In the run up to the 2012 US election, President Obama visited the undecided swing-states he needed to win in order to hold on to the Presidency. A new study published in the Journal of Language and Social Psychology features an analysis of the speeches he gave, together with those of his opponent Mitt Romney, and finds it’s possible to estimate the candidates’ subsequent electoral success by measuring how audiences reacted to their speeches. It also describes how speeches are intentionally ........ Read more »

Fish Guts and Cancer

by Mark Lasbury in As Many Exceptions As Rules

E. fishelsoni s a bacterium that breaks the rules. It grows from 10 µm long to a fully visible 0.7 mm….in twelve hours! Normally, diffusion isn’t adequate for a bacterium this big because it takes too long for two interacting proteins to find one another. But what if the bacterium make more of the protein, so much more that it can find a partner all the time. How can you make that much of each protein? E. fishelsoni does it by making 85,000 copies of its genome….. ever........ Read more »

Do you make choices as to whom you  leave waiting in the crosswalk? 

by Doug Keene in The Jury Room

Apparently yes, at least according to today’s researchers. And you likely will be somewhat taken aback by just which group you choose to make wait. Researchers wanted to study whether the pedestrian’s race had anything to do with yielding behavior of motorists at crosswalks. They tested with 173 motorists and 6 trained male pedestrian-confederates (3 […]

Explorations of Mars with probes and spacecraft are revealing intriguing features of the Red Planet. The most recent discovery by the NASA spacecraft Mars Reconnaissance Orbiter, that liquid water very likely flows on Mars, has stirred enthusiasm among scientists who have been looking for signs of “life-as-we-know-it” on the planet for the last twenty years.

Obesity Is Not Like Being "Addicted to Food"

by The Neurocritic in The Neurocritic

Credit: Image courtesy of Aalto UniversityIs it possible to be “addicted” to food, much like an addiction to substances (e.g., alcohol, cocaine, opiates) or behaviors (gambling, shopping, Facebook)? An extensive and growing literature uses this terminology in the context of the “obesity epidemic”, and looks for the root genetic and neurobiological causes (Carlier et al., 2015; Volkow & Bailer, 2015).Fig. 1 (Meule, 2015). Number of scientific publications on food addiction (1990-2014........ Read more »
