Immunity genes could protect some from E. coli while others fall ill

DURHAM, N.C. -- When a child comes home from preschool with a stomach bug that threatens to sideline the whole family for days, why do some members of the family get sick while others are unscathed?

According to a Duke Health study published Jan. 19, 2016 in the Journal of Infectious Diseases, a person's resistance to certain germs, specifically E. coli bacteria, could come down to their very DNA.

Emotions matter -- dogs view facial expressions differently

A recent study from the University of Helsinki shows that the social gazing behavior of domestic dogs resembles that of humans: dogs view facial expressions systematically, preferring eyes. In addition, the facial expression alters their viewing behavior, especially in the face of threat. The study was published in the science journal PLOS ONE 13.1.2016.

Threatening faces evoke unique responses in dogs

Breakthrough in human cell transformation could revolutionize regenerative medicine

A breakthrough in the transformation of human cells by an international team led by researchers at the University of Bristol could open the door to a new range of treatments for a variety of medical conditions. Their paper, published today in Nature Genetics, demonstrates the creation of a system that predicts how to create any human cell type from another cell type directly, without the need for experimental trial and error.

Position paper goes against previous recommendations on gluten introduction to prevent celiac disease

Jan. 18, 2016 - Based on new evidence, the age of introduction of gluten into the infant diet -- or the practice of introducing gluten during breast-feeding -- does not reduce the risk of celiac disease in infants at risk, according to a Position Paper in the Journal of Pediatric Gastroenterology and Nutrition<.

Scientists demonstrate basics of nucleic acid computing inside cells

Using strands of nucleic acid, scientists have demonstrated basic computing operations inside a living mammalian cell. The research could lead to an artificial sensing system that could control a cell's behavior in response to such stimuli as the presence of toxins or the development of cancer.

Harmful mutations have accumulated during early human migrations out of Africa

The researchers analysed genomes of individuals across four continents while former studies had only been carried out on two populations. The study has now been published in the Proceedings of the National Academy of Sciences.

Weight gain through plasticizers

Plasticisers such as phthalates are always found in plastics. They can get into our bodies through the skin or by the diet. They affect our hormone system and are suspected of having an influence on our body weight. The exact correlations and mechanisms have been unclear thus far.

Eating less meat might not be the way to go green, say researchers

Reduced meat consumption might not lower greenhouse gas emissions from one of the world's biggest beef producing regions, new research has found. The finding may seem incongruous, as intensive agriculture is responsible for such a large proportion of global greenhouse gas emissions.

No more needles at the dentist -- just a tiny electric current instead

Amsterdam, Jan. 18, 2016 - If you're scared of the dentist's needles you're not alone -- but new research means you might not have to put off that appointment again. A study published in Colloids and Surfaces B: Biointerfaces reveals how the dentist could give you anesthetic using a tiny electric current instead of a needle.

Revealing the intra-cellular mechanism underlying ALS

Kyoto, Japan -- A new study uncovering the mechanism behind amyotrophic lateral sclerosis (ALS or also Lou Gehrig's disease) has brought doctors a step closer to identifying drug targets for the malady. Tsukasa Uchida and collaborators at Kyoto University have identified proteins associated with cancer suppression and prevention of hypoxia as key players in the progression of ALS.

Protein 'handbrake' halts leukaemia in its tracks

Melbourne researchers have showed that they can stop leukaemia in its tracks by targeting a protein that puts the handbrake on cancer cell growth.

The researchers discovered that targeting a protein called Hhex could cure acute myeloid leukaemia (AML) in preclinical disease models, and could be a key target for new therapies for human leukaemia.

1,541 snout moth species and counting in the United States and Canada

The present snout moth list contains a ten-percent increase in the number of species since 1983. For the last thirty-three years snout moth specialists in the United States and Canada have been describing species new to science and recording species new to these two countries. Scientists have also published studies resulting in major changes to the classification above the species level, for example by studying snout moth "ears" (tympanal organs) and utilizing genes to study their relationships.

Real acupuncture no better than sham acupuncture for treating hot flushes: Study

But, in a surprise finding, both the real and sham treatments showed a 40 per cent improvement in the severity and frequency of hot flushes at the end of eight weeks of treatment. The benefits were sustained at six months after treatment.

The University of Melbourne study, funded by the NHMRC and supported by Jean Hailes for Women, is the largest of its kind to date.

Scientists propose an algorithm to study DNA faster and more accurately

A team of scientists from Germany, USA, and Russia, including Dr. Mark Borodovsky, a Chair of the Department of Bioinformatics at MIPT, have proposed an algorithm to automate the process of searching for genes, making it more efficient. The new development combines the advantages of the most advanced tools for working with genomic data. The new method will enable scientists to analyse DNA sequences faster and more accurately and identify the full set of genes in a genome.

First study of arthropods in US homes finds huge biodiversity

The first study to evaluate the biodiversity of arthropods in U.S. homes finds that humans share their houses with any of more than 500 different kinds of arthropods - at least on a short-term basis. Arthropods are invertebrate animals with exoskeletons, segmented bodies and jointed limbs, such as insects, spiders, mites and centipedes.
