Chemotherapy can cause drug-resistant mutations in pediatric ALL patients who relapse

Chemotherapy has helped make the most common childhood cancer one of the most curable, but researchers have evidence that the treatment may also prime some patients for relapse.

Survey: Less than 40% of nurse respondents aware of ICU-specific Choosing Wisely recommendations

A national survey of acute and critical care nurses finds that measures to reduce unnecessary testing and treatments are increasingly being integrated into clinical practice, even though most respondents are not aware of the campaign behind the specific recommendations.

Varied diets may be the cause for differences in human and non-human primate saliva

The study, published recently in Molecular Biology and Evolution, describes the discovery that human saliva is much more watery than the saliva of chimpanzees and gorillas.

Mechanism for antibiotic resistance in Pseudomonas explained in new research

A new study has revealed the underlying mechanism of development of antibiotic resistance among Pseudomonas aeruginosa (P. aeruginosa). Pseudomonas is known to cause severe and often life threatening infections in humans. These infections become further difficult to treat because of the development of resistance against commonly used antibiotics.

New study sheds light on artificial networks and human face recognition

Our brains are so primed to recognize faces - or to tell people apart - that we rarely even stop to think about it, but what happens in the brain when it engages in such recognition is still far from understood. In a new study reported today in Nature Communications, researchers at the Weizmann Institute of Science have shed new light on this issue.

New technique could replace conventional methods of testing paralytic neurotoxins

Animal testing will no longer be required to assess a group of deadly neurotoxins, thanks to University of Queensland-led research.

DNA sequences encode information in many different ways

DNA sequences encode information in many different ways. Codons specify the amino acids involved in making a protein.

Botswana now the origin of humans

A group of scientists have reported their new theory that human life was first seen in northern Botswana, south of the Zambezi river in Africa, according to their article published in the journal Nature.

Study sheds new light on mechanism behind evolution of antibiotic resistance

Researchers have provided new insight into a mechanism behind the evolution of antibiotic resistance in a type of bacterium that causes severe infections in humans.

Narcissistic traits can lower stress levels and reduce chances of depression

People who have grandiose narcissistic traits are more likely to be 'mentally tough', feel less stressed and are less vulnerable to depression, research led by Queen's University Belfast has found.

NSU study points to another potential connection between sleep and overall good health

As if you didn't already have enough to worry about to keep you up at night, a new study indicates that poor sleep can negatively affect your gut microbiome, which can, in turn, lead to additional health issues.

Study uses whole-genome sequencing for early identification and containment of AMR pathogens

A study published today in PNAS examines the evolutionary and epidemiologic history of an epidemic strain of extensively drug-resistant tuberculosis (XDR-TB) - called LAM4/KZN- in KwaZulu-Natal, South Africa.

Researchers use 3D electron microscopy to unravel dense networks in the cerebral cortex

Unlike any other organ, our brains contain extremely densely packed networks of membranous cables that are used by our about 86 billion nerve cells for communication amongst each other.

Gene linked to schizophrenia likely confers risk for illness

Researchers have discovered in mice how one of the few genes definitively linked to schizophrenia, called SETD1A, likely confers risk for the illness. Mice genetically engineered to lack a functioning version of the enzyme-coding gene showed abnormalities in working memory, mimicking those commonly seen in schizophrenia patients.

Proactive administration of amiodarone to patients after common heart surgery improves outcomes

Proactive administration of amiodarone to patients recovering from a common heart surgery shows promise in preventing postoperative atrial fibrillation, a serious and expensive complication with potential long-term consequences.

Wyss Institute joins Global Virus Network as new Center of Excellence to fight viral threats

Today, the Global Virus Network, a conglomerate of 52 "Centers of Excellence" and 9 Affiliates in 32 countries, which catalyzes collaborative research into diseases caused by every class of virus in humans and animals, announced the Wyss Institute for Biologically Inspired Engineering at Harvard University as a new Center of Excellence.

Hong Kong Baptist University receives FDA orphan drug designation for novel aptamer

A research team from the School of Chinese Medicine at Hong Kong Baptist University has successfully developed a novel aptamer, i.e. a single-stranded piece of DNA, for the treatment of osteogenesis imperfecta (OI) with the aid of artificial intelligence (AI) technology.

Lifestyle of bacteria determines how they evolve antibiotic resistance

How bacteria live -- whether as independent cells or in a communal biofilm -- determines how they evolve antibiotic resistance, which could lead to more personalized approaches to antimicrobial therapy and infection control.

E. coli bacteria study may provide clues about drug resistance

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife.

Taste neurons could be controlling feeding behaviour find researchers

Researchers from the University of California, Riverside used a common fruit fly (Drosophila melanogaster) to find the association between taste neurons and control of feeding behaviours. They noted that if they genetically modulated these flies, they could make them selectively avoid certain chemicals including acids, bitter compounds, salty substances etc. The results of their study appeared in the October issue of the journal Cell Reports.
