Technology news

A new roving biologger that travels along a sperm whale's body surface

A team of researchers at Yamagata University and Teikyo University of Science, in Japan, have recently developed a new roving biologger, or whale rover, which can travel along a sperm whale's body surface and collect valuable behavioral data. Biologging entails the biological tracking of individual animals, typically by attaching small dataloggers directly to their bodies. It can be a very effective way of unfolding the mysteries of animal life, by collecting data and observations related to an animal's behavior, motion, and biology.

Some fibroblasts have the ability to convert into fat cells that reside under the dermis, giving the skin a plump, youthful look and producing a peptide that plays a critical role in fighting infections.

Cell size and cell-cycle states play key decision-making role in HIV

Thanks to the development of antiretroviral drugs, human immunodeficiency virus (HIV) is considered a manageable chronic disease today.

Better mouse model built to enable precision-medicine research for Alzheimer's

Incorporating genetic diversity into a mouse model of Alzheimer's disease resulted in greater overlap with the genetic, molecular and clinical features of this pervasive human disease, according to a study funded by the National Institute on Aging (NIA), part of the National Institutes of Health. The study also suggests that adding genetic diversity may be key to improving the predictive power of studies using mouse models and increasing their usability for precision medicine research for Alzheimer's. This research comes out of the newly established Resilience-Alzheimer's Disease Consortium (Resilience-AD) and was published online Dec. 27, 2018 in the journal Neuron.

The study appears in JAMA Oncology.

How exercise reduces belly fat in humans

Some of you may have made a New Year's resolution to hit the gym to tackle that annoying belly fat. But have you ever wondered how physical activity produces this desired effect? A signaling molecule called interleukin-6 plays a critical role in this process, researchers report December 27 in the journal Cell Metabolism.

Your brain rewards you twice per meal: When you eat and when food reaches your stomach

We know a good meal can stimulate the release of the feel-good hormone dopamine, and now a study in humans from the Max Planck Institute for Metabolism Research in Germany suggests that dopamine release in the brain occurs at two different times: at the time the food is first ingested and another once the food reaches the stomach. The work appears December 27 in the journal Cell Metabolism.

The brain's support cells show defective development in Huntington's disease

The neurological disorder Huntington's disease causes behavioural and motor changes, which among other things are a result of dysfunctional maturation or formation of glial cells, the brain's support cells, researchers from the University of Copenhagen demonstrate in a new study based on mouse trials. The researchers' long-term goal is to be able to use the research results to develop a treatment for Huntington's disease using glial cells.

Losing neurons is sometimes not all bad

In the largest population genomics investigation to date, a team of researchers at the Icahn School of Medicine at Mount Sinai, Stanford University, and the University of Colorado have discovered that kidney disease risk variants of the gene APOL1, previously known to affect African and African American populations, are also found at appreciable frequencies in Caribbean and Latin American populations. Because these populations are historically under-studied and under-tested in connection with APOL1, the gene's impact on these populations is currently unknown. The findings were described in a publication released today in The New England Journal of Medicine.

For years, the diagnosis of scabies has relied on time-consuming and intrusive full-body examinations. Now, researchers reporting in PLOS Neglected Tropical Diseases have found that an exam of just a patient's hands, feet and lower legs may have the potential to catch more than 90 percent of all scabies cases, regardless of severity. These speedier exams may be useful in public health assessments on the prevalence of scabies.

Contact with monkeys and apes puts populations at risk

Animal diseases that infect humans are a major threat to human health, and diseases often spillover to humans from nonhuman primates.

Interpreting emotions: A matter of confidence

We are constantly exposed to the facial expressions of the people around us, expressions that reflect their emotions. But do we interpret them correctly? And do we trust our own judgment? This trust is essential for avoiding misunderstandings or even potentially dangerous situations. That is the reason why researchers from the University of Geneva (UNIGE) and University Hospitals of Geneva (HUG), Switzerland, have been testing how confident we feel when judging other people's emotions, and what areas of the brain are used. These results—which you can read all about in the journal Social, Cognitive and Affective Neuroscience - demonstrate that beliefs of our own emotional interpretation stem directly from the experiences stored in our memory. In other words, our past life influences our interpretations... and sometimes leads us astray.
