Researchers discover a key to making new muscles
A new study finds that cyclic bursts of a STAT3 inhibitor can replenish muscle stem cells and promote their differentiation into muscle fibers.

Rethinking the basic science of graphene synthesis
A new route to making graphene has been discovered that could make the 21st century's wonder material easier to ramp up to industrial scale.

The Lancet HIV: High rates of recreational drug use among HIV-positive gay and bisexual men in the UK strongly linked with condomless sex
New research published in The Lancet HIV shows that polydrug use is common among HIV-positive men who have sex with men and is strongly linked to sex without a condom.

Electronic nose can detect sub-groups of asthma in children
An electronic nose can be used to successfully detect different sub-groups of asthmatic children, according to a new study.

Trial shows improved overall survival for patients with liver cancer not amenable to surgery
The mature results from a trial conducted by the Asia-Pacific Hepatocellular Carcinoma Trials Group led by the National Cancer Centre Singapore and Singapore General Hospital have shown that patients who suffer from inoperable advanced hepatocellular carcinoma may have a chance to live significantly longer by using a combined therapy.

Inexpensive lab test identifies resistant infections in hours
Researchers from Oregon State Public Health Lab have modified the protocol for a relatively new test for a dangerous form of antibiotic resistance, increasing its specificity to 100 percent.

Dynamic duo takes out the cellular trash
Salk scientists identify how immune cells use two critical receptors to clear dead cells from the body, pointing the way to new autoimmune and cancer therapies.

Ultra-thin, high-speed detector captures unprecedented range of light waves
Research at the University of Maryland could lead to light detectors that can see below the surface of bodies, walls, and other objects, with applications in emerging terahertz fields such as mobile communications, medical imaging, chemical sensing, night vision, and security.

New antifungal as effective as existing drugs with fewer adverse events
A newly developed antifungal, isavuconazole, is as effective as an existing drug, voriconazole, against invasive mold disease in cancer patients with less adverse effects, according to phase 3 clinical data presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy, an infectious disease meeting of the American Society for Microbiology.

Targeting the protein-making machinery to stop harmful bacteria
In an effort to kill harmful bacteria -- including so-called super-bugs -- many scientists have been focusing on the ribosomes, which manufacture a cell's proteins.

Timing of food intake could impact the effectiveness of TB treatment
The timing of food intake in the early phase of TB treatment could have a negative impact on the effectiveness of TB treatment.

The Lancet Respiratory Medicine: Benralizumab for chronic obstructive pulmonary disease and sputum eosinophilia
Chronic obstructive pulmonary disease is associated with eosinophilic airway inflammation in 10-20 percent of patients.

Why age reduces our stem cells' ability to repair muscle
As we age, stem cells throughout our bodies gradually lose their capacity to repair damage, even from normal wear and tear.

Continuing Bragg legacy of structure determination
Over 100 years since the Nobel Prize-winning father and son team Sir William and Sir Lawrence Bragg pioneered the use of X-rays to determine crystal structure, University of Adelaide researchers have made significant new advances in the field.

61 percent fall in female genital warts due to free HPV vaccine
General practitioners in Australia are managing 61 percent less cases of genital warts among young women since the introduction of the national human papillomavirus vaccination program, a new study from the University of Sydney reveals.

'Pick 'n' Mix' chemistry to grow cultures of bioactive molecules
Chemists at ETH-Zuerich and ITbM, Nagoya University have developed a new method to build large libraries of bioactive molecules -- which can be used directly for biological assays -- by simply mixing a small number of building blocks in water.

Flour identified as the main cause of occupational asthma in France
Flour has been identified as the main cause of occupational asthma in France, closely followed by cleaning products.

Sleeping on animal fur in infancy found to reduce risk of asthma
Sleeping on animal fur in the first three months of life might reduce the risk of asthma in later childhood a new study has found.

Ultraviolet light-induced mutation drives many skin cancers, Stanford researchers find
A genetic mutation caused by ultraviolet light is likely the driving force behind millions of human skin cancers, according to researchers at the Stanford University School of Medicine.

Each day in the hospital raises risk of multidrug-resistant infection
If a patient contracts an infection while in the hospital, each day of hospitalization increases by 1 percent the likelihood that the infection will be multidrug-resistant, according to research presented at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy, an infectious disease meeting of the American Society for Microbiology.

Platelet-like particles augment natural blood clotting for treating trauma
A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries -- and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets.
