Why we love it or hate it: The 3 E's
Why do brands such as Manchester United and Apple capture hearts and minds? How do marketers make consumers develop a strong attachment for a product or service? According to a recent study from USC Marshall School of Business, it is achieved by appealing to people's aesthetic needs (enticing/annoying to the self), functional needs (enabling/disabling for the self) and spiritual needs (whether something is enriching/impoverishing).

4 Rutgers professors elected members of the National Academy of Sciences
Four Rutgers professors are among 84 distinguished researchers elected to membership in the National Academy of Sciences this year, one of the highest honors an American scientist or engineer can achieve.

Salt levels in food still dangerously high
The dangerously high salt levels in processed food and fast food remain unchanged, despite numerous calls from health agencies for the food industry to voluntarily reduce sodium. Excess sodium in the diet is a major cause of high blood pressure and prematurely kills up to 150,000 people in the US each year. The government must regulate sodium, the study says.

USF researchers find far-reaching, microvascular damage in uninjured side of brain after stroke
An animal-model study led by researchers at the University of South Florida finds far-reaching microvascular damage in the uninjured side of the brain after a stroke.

Collecting DNA for human rights: How to help while safeguarding privacy
DNA databases might help identify victims of crime and human trafficking, but how do we safeguard the personal privacy of innocent victims and family members? A new report online May 15 in the Cell Press journal Trends in Genetics identifies a number of key challenges to consider as experts develop such programs.

Simplified solutions to deforestation ineffective in the long run
Deforestation is the second largest source of CO2 emissions after consumption of fossil fuels. So-called PES programs, where landowners are paid to replant or protect forests, have been promoted as a way to reduce deforestation. However, the effectiveness of the programs has been questioned, and new research from the School of Business, Economics and Law at the University of Gothenburg, Sweden, points to potential negative long-term effects and a need for broader guidelines and policies.

Focus on STD, not cancer prevention, to promote HPV vaccine use
The HPV vaccine can prevent both cervical cancer and a nasty sexually transmitted disease in women. But emphasizing the STD prevention will persuade more young women to get the vaccine.

Low-dose anticoagulation therapy used with new design mechanical heart valve lowers bleeding risk
Investigators show that lower dose anticoagulation therapy, combined with low-dose aspirin, resulted in a reduction of 55 to 60 percent of the incidence of adverse bleeding events without significant increases in stroke, transient ischemic attack or total neurological events when used in conjunction with the On-X mechanical aortic valve.

A survey of GPs reveals that many identify nicotine as a harmful cigarette-smoke component
A survey of GPs in the UK and Sweden revealed that some believe nicotine to be one of the greatest health risks from smoking. Nicotine is addictive, but unlike some other constituents of tobacco smoke, it is not carcinogenic. Switching to alternative nicotine products can, therefore, help smokers quit smoking or cut down. But GPs views may influence their recommendations on the use of alternative nicotine products to quit or cut down.

Gemini Observatory captures Comet ISON hurtling toward uncertain destiny with the Sun
A new series of images from Gemini Observatory shows Comet C/2012 S1 racing toward an uncomfortably close rendezvous with the Sun. In late November the comet could present a stunning sight in the twilight sky and remain easily visible, or even brilliant, into early December of this year.

Could eating peppers prevent Parkinson's?
New research reveals that Solanaceae--a flowering plant family with some species producing foods that are edible sources of nicotine--may provide a protective effect against Parkinson's disease. The study appearing today in Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, suggests that eating foods that contain even a small amount of nicotine, such as peppers and tomatoes, may reduce risk of developing Parkinson's.

New computer-based tool measures readability for different readers
Today most public services involve electronic communication, which requires that people are able to read relatively well. However, a significant number of adults cannot fully understand the texts they read for example on the internet. A new doctoral thesis from the University of Gothenburg shows that a new model called SVIT can be used as a tool to measure the readability of texts and therefore how appropriate they are for different target groups.

Little is known about the effect of physical education on child weight, but a new study from Cornell University finds that increasing the amount of time that elementary schoolchildren spent in gym class reduces the probability of obesity.

Where on Earth did the moon's water come from?
Water is perhaps the most important molecule in our solar system. Figuring out where it came from and how it was distributed within and among the planets can help scientists understand how planets formed and evolved. New research from a team including Carnegie's Erik Hauri demonstrates that water from the interiors of the Earth and moon has a common origin.

Dehydration is a problem in combat sports
Athletes in combat sports often try to shed body weight in order to compete against lighter and smaller opponents. A new doctoral thesis from the University of Gothenburg, Sweden, points to the human body's limited ability to quickly recover following extensive short-term weight loss. Almost half of the studied athletes were severely dehydrated on the morning of their matches.

Team describes molecular detail of HIV's inner coat, pointing the way to new therapies
A team led by researchers at the University of Pittsburgh School of Medicine has described for the first time the 4-million-atom structure of the HIV's capsid, or protein shell. The findings, reported today in Nature, could lead to new ways of fending off an often-changing virus that has been very hard to conquer.

A specially-designed tracheal splint, made from a biopolymer using 3D printing, was created and used at the University of Michigan to save a baby from life-threatening tracheobronchomalacia.

Women's immune systems remain younger for longer
Women's immune systems age more slowly than men's, suggests research in BioMed Central's open access journal Immunity & Ageing. The slower decline in a woman's immune system may contribute to women living longer than men.

Iodine deficiency during pregnancy may adversely affect children's mental development
A study of around 1,000 UK mothers and their children, published in The Lancet, has revealed that iodine deficiency in pregnancy may have an adverse effect on children's mental development. The research raises concerns that the iodine status of pregnant women is a public health issue that needs to be addressed.

Pathogen turns protein into a virulence factor in 1 easy step
To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. In a study to be published May 7 in mBio researchers uncover this previously unknown virulence factor in P. aeruginosa, one of the most common causes of hospital-acquired pneumonia.

Study identifies possible new acute leukemia marker, treatment target
A study has identified microRNA-155 as a new independent prognostic marker and treatment target in patients with acute myeloid leukemia that has normal-looking chromosomes under the microscope (that is, cytogenetically normal acute myeloid leukemia). The findings suggest that this molecule is important in leukemia development and should be targeted by a drug that will inhibit it.

Leading explanations for whooping cough's resurgence don't stand up to scrutiny
Whooping cough has exploded in the United States and some other developed countries in recent decades, and many experts suspect ineffective childhood vaccines for the alarming resurgence.

Bacterial infection in mosquitoes renders them immune to malaria parasites
Scientists funded by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, have established an inheritable bacterial infection in malaria-transmitting Anopheles mosquitoes that renders them immune to malaria parasites. Specifically, the scientists infected the mosquitoes with Wolbachia, a bacterium common among insects that previously has been shown to prevent malaria-inducing Plasmodium parasites from developing in Anopheles mosquitoes.

Cancer drug prevents build-up of toxic brain protein
Researchers have used tiny doses of a leukemia drug to halt accumulation of toxic proteins in the brains of mice. They say their study offers a unique and exciting strategy to treat neurodegenerative diseases that feature abnormal buildup of proteins in Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease and Lewy body dementia, among others.
