Calorie restriction during treatment for breast cancer changes cellular programming in a way that lowers the chance of metastases in mice.

Sex-specific changes in cerebral blood flow begin at puberty, Penn study finds
Penn Medicine researchers have discovered that cerebral blood flow levels decreased similarly in males and females before puberty, but saw them diverge sharply in puberty, with levels increasing in females while decreasing further in males, which could give hints as to developing differences in behavior in men and women and sex-specific pre-dispositions to certain psychiatric disorders.

NTU launches $30 million 3-D printing research center
Medical devices and tissue printing are among the key research areas that Nanyang Technological University is ramping up on with the launch of its new $30 million 3-D printing center.

Molecules do the triple twist
An international research team led by Academy Professor Kari Rissanen of the University of Jyväskylä (Finland) and Professor Rainer Herges of the University of Kiel (Germany) has managed to make a triple-Möbius annulene, the most twisted fully conjugated molecule to date, as reported in Nature Chemistry (DOI:10.1038/nchem.1955, published online 25 May 2014).

New perspectives to the design of molecular cages
Researchers from the University of Jyväskylä report a new method of building molecular cages.

The perception of discrimination is greater among younger immigrants
The group of young immigrants (18- to 24-year-olds) has to cope with a whole host of challenges that may give rise to anxiety as well as feelings of embarrassment, insecurity, failing to integrate into the new social context, etc.

Hot flashes/night sweats solutions: Estrogen therapy vs. venlafaxine
A new research study from Brigham and Women's Hospital that compares low-dose oral estrogen and low-dose non-hormonal venlafaxine hydrochloride extended release to placebo were both found effective in reducing the number of hot flashes and night sweats reported by menopausal women.

Implications of mandatory flu vaccinations for health-care workers
Employers planning to implement mandatory influenza vaccination policies for health-care workers need to understand the implications, according to an analysis published in CMAJ.

Inhaling hypertonic saline decreases hospital admissions in children with bronchiolitis
A team of researchers, led by physicians from Children's Hospital Los Angeles, have found that infants with bronchiolitis who were treated with inhaled hypertonic saline in the emergency department were less likely to require admission to the hospital compared to infants treated with normal saline.

Does apolipoprotein E mimetic peptide reduce neuronal apoptosis induced by DBI?

A mechanism of how biodiversity arises
The study in the cichlid fish model by evolutionary biologists at UMass Amherst is among the first to address how a single genetic change can influence both trait development and function.

Conflicting conclusions in 2 bronchiolitis studies; editorial explains why
Children with bronchiolitis (a common respiratory tract infection that can result in hospitalization) who were treated in the emergency department showed less clinical improvement after receiving nebulized 3 percent hypertonic saline than infants who received normal saline.

Relaxation helps pack DNA into a virus
DNA packs more easily into the tight confines of a virus when given a chance to relax.

New biodiversity study throws out controversial scientific theory
A research team led by Sean Connolly, ARC Centre of Excellence for Coral Reef Studies, has today released ground-breaking findings that dismiss the 'Neutral Theory of Biodiversity'.

Funding for better understanding of cancer-causing cell defect
A research team from Plymouth University Peninsula Schools of Medicine and Dentistry has received funding from the Biotechnology and Biological Sciences Research Council for research to better understand a cell defect that contributes to diseases such as cancer.

Neurons can use local stores for communication needs
Researchers have revealed that neurons can utilize a supremely localized internal store of calcium to initiate the secretion of neuropeptides, one class of signaling molecules through which neurons communicate with each other and with other cells.

Breakthrough shows how DNA is 'edited' to correct genetic diseases
An international team of scientists has made a major step forward in our understanding of how enzymes 'edit' genes, paving the way for correcting genetic diseases in patients.

Immunologists discover immune system precursor cells that fight infection
The innate immune system recognizes infectious agents such as viruses and bacteria.

Ebola vaccine success highlights dilemma of testing on captive chimps to save wild apes
A study illustrates 'high conservation potential' of vaccines for endangered wild primates devastated by viral disease, but highlights need for access to captive chimpanzees so vaccines can be trialled before being administered in the wild.

Using thoughts to control airplanes
Pilots of the future could be able to control their aircraft by merely thinking commands.

A novel disease-preventing antioxidant pathway
A team in Singapore has recently showed that uric acid is a major intracellular antioxidant, possibly even more important than the antioxidants we try to eat.

At New Delhi's racecourse races are rigged
Bookmakers, compulsive gamblers, prostitutes and incredibly rich Indians were last year part of PhD Stine Simonsen Puri's daily entourage.

Ants are capable of complex problem-solving strategies that could be widely applied as optimization techniques.

Melatonin makes old bones stronger
Faleh Tamimi, a professor in McGill's School of Dentistry, is the leader of a research team that has just discovered that melatonin supplements make bones stronger in elderly rats and therefore, potentially, in elderly humans too.
