PRINCETON, N.J.—You only live once. Carpe diem. You can't take it with you. As often as we hear these clichés, they might include some real economic wisdom for some, according to research led by Princeton University's Woodrow Wilson School. The researchers argue in the Journal of Mathematical Economics that some people might want to spend more and work less – just in case their time runs out. Marc Fleurbaey, the Robert E. Kuenne Professor in Economics and Humanistic Studies and professor of public affairs, and his collaborators – Marie-Louise Leroux from the University ...

Wireless data connections that exploit millimetre wave radio spectrum (30GHz to 300GHz) are expected to be used in worldwide 5G networks from 2020. The University of Bristol's Communication Systems and Networks research group has partnered with Bristol start-up Blu Wireless Technology (BWT) to develop this technology and they will demonstrate their innovative work at the Small Cells World Summit in London this week [10-12 June]. Millimetre wave radios use much higher carrier frequencies than those in current systems, such as 4G and Wi-Fi. The University and BWT radios ...

The future face of modern-day anti-cancer therapy based on charged particles like protons could potentially involve using laser accelerators. However, these facilities will need to be reduced in terms of both size and cost compared to conventional ones. In the scientific journal, Applied Physics B, Dresden medical physicist Umar Masood is the first to present a new design for the entire complex machine – from the accelerator to the radiation site. In the process, he has successfully cut the facility's size in half. In the fight against cancer, proton therapy is especially ...

This news release is available in Spanish. The development of a wind farm is a process in which various factors need to be taken into consideration to ensure that the resource is properly used and that appropriate planning is carried out to minimise the effects it could have. "The fundamental parameter to take into account when designing a wind farm is the wind or wind potential. Another very important factor is the orography of the land," explained David de la Vega, a member of the Signal Processing and Radiocommunications Group (TSR). "Apart from these two main factors, ...

One of the defining features of cells is their membranes. Each cell's repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, but, despite decades of research, even the most basic membrane structures, known as vesicles, still face many problems when made in the lab. They are difficult to make at consistent sizes and lack the stability of their biological counterparts. Now, University of Pennsylvania researchers have shown that a certain kind of dendrimer, a molecule ...

An NYU Langone internal medicine specialist who served as a White House fellow at the US Department of Veteran's Affairs says the headline-grabbing failures of the VA health system's administration stand in sharp contrast to the highly rated care the system delivers. In an editorial in The New England Journal of Medicine online June 5, Dave Chokshi, MD, MS, an assistant professor at NYU Langone Medical Center, says the paradox has created a watershed moment to reform and refocus the way the entire system is structured, staffed, and managed, while also building on its ...

A Connecticut hospital saw a 50% drop in malpractice liability claims and payments when it made patient safety initiatives a priority by training doctors and nurses to improve teamwork and communication, hiring a patient safety nurse, and standardizing practices, according to a study by Yale School of Medicine researchers. The results, published in the June 9 online issue of the American Journal of Obstetrics and Gynecology, come at a time when mounting concerns about liability are thinning the ranks of obstetricians in the United States, according first author Christian ...

Specialist researchers from LSTM have identified the diverse mechanisms by which variations in venom occur in related snake species and the significant differences in venom pathology that occur as a consequence. Working with colleagues from Bangor University and Instituto de Biomedicina de Valencia in Spain, the team assessed the venom composition of six related viperid snakes, examining the differences in gene and protein expression that influence venom content. The research, published in PNAS, also assessed how these changes in venom composition impacted upon venom-induced ...

Popular diets across the world typically focus on the right balance of essential components like protein, fat, and carbohydrates. These items are called macronutrients, and we consume them in relatively large quantities. However, micronutrients often receive less attention. Micronutrients are chemicals, including vitamins and minerals, that our bodies require in very small quantities. Common mineral micronutrients include zinc, iron, manganese, magnesium, potassium, copper, and selenium. A recent study published in Crop Science examined the mineral micronutrient content ...

How the Neolithic people found their way to Europe has long been a subject of debate. A study published June 6 of genetic markers in modern populations may offer some new clues. Their paper, "Maritime route of colonization of Europe," appears in the online edition of the Proceeding of the National Academy of Sciences. Between 8,800 to 10,000 B.C., in the Levant, the region in the eastern Mediterranean that today encompasses Israel and the West Bank, Jordan, Syria and part of southern Turkey, people learned how to domesticate wild grains. This accomplishment eventually ...

MAYWOOD, Ill. – In the fight against teenage obesity, some researchers have proposed targeting popular teens, in the belief that such kids would have an outsize influence on their peers. But in a Loyola University Chicago study, researchers were surprised to find that this strategy would be only marginally more effective than targeting overweight kids at random. Results are published in the journal Social Science & Medicine. "I don't think targeting popular kids would be worth the extra effort it would take to identify them," said David Shoham, PhD, MSPH, senior ...

WASHINGTON, D.C., June 10, 2014 ─ The conventional wisdom that No Child Left Behind (NCLB) has eroded teacher job satisfaction and commitment is off the mark, according to new research published online today in Educational Evaluation and Policy Analysis, a peer-reviewed journal of the American Educational Research Association. "Estimating the Effects of No Child Left Behind on Teachers and Their Work Environment," by Jason A. Grissom of Vanderbilt University, Sean Nicholson-Crotty of Indiana University, and James R. Harrington of the University of Texas at Dallas, ...

Vancouver, BC - Today the International Cooperation to Sequence the Atlantic Salmon Genome (ICSASG) announced completion of a fully mapped and openly accessible salmon genome. This reference genome will provide crucial information to fish managers to improve the production and sustainability of aquaculture operations, and address challenges around conservation of wild stocks, preservation of at-risk fish populations and environmental sustainability. This breakthrough was announced at the International Conference on Integrative Salmonid Biology (ICISB) being held in Vancouver ...

Increasingly, scientific findings indicate that an organism's diet affects more than just general health and body condition. In an article published in a forthcoming issue of the journal Physiological and Biochemical Zoology, researchers from Nicolaus Copernicus University have found evidence that the diet of some animals must include cholesterol in order for them to enter necessary periods of energy conservation known as torpor. Torpor is a temporary, strategic decrease of body temperature and metabolic, heart, and respiration rates that can enable an organism to survive ...

London, June 10, 2014 – Papers published in the latest themed issue of Reproductive Health Matters demonstrate the extent of evidence and progressive thinking around population dynamics and sustainability that is informing development policies and programs. The theme of this issue is timely given that meetings and negotiations are currently taking place around the world to decide what will be included in the post-2015 development goals. The discussions about the post-2015 agenda have focused on calling out to sexual and reproductive health and rights (SRHR) advocates ...

Chastity belts were not first thought out in mediaeval times – members of many animal groups have evolved similar mechanical safeguards to ensure their paternity. Male dwarf spiders, for instance, use mating plugs to block off the genital tract of the female they have just mated with. The larger and older the plug, the better the chances are that other males will not make deposits in a female's sperm storage organ, too. So says Katrin Kunz and co-authors of the Zoological Institute and Museum in Greifswald, Germany, in an article published in Springer's journal Behavioral ...

After initially visiting a school psychologist, adolescents in the United States with a mental disorder often go to seek care from their pediatricians or family doctors. Fewer of them continue their treatment directly with a psychotherapist or doctor specialized in mental disorders. This shows an analysis conducted by scientists at the University of Basel that has just been published in the academic journal PLOS ONE. The results are based on a nationally representative cohort of 6,500 U.S. teenagers. A considerable number of children and adolescents suffer from a mental ...

Australian researchers are zeroing in on a promising new approach to killing off cancer cells in patients with leukemia. In a study led by the South Australian Health and Medical Research Institute (SAHMRI) and the University of Adelaide's Centre for Personalised Cancer Medicine, researchers have found that cancer cells decide whether to live or die after a short period of intense exposure to targeted therapy, opposing the current requirement for continuous treatment. The researchers say this study presents a new treatment strategy which will translate to a significant ...

This news release is available in Spanish. Women are the subject of news in sports papers in only 5.11% of the cases, sometimes alone (2.18%) and others accompanied by men (2.93%). On the other hand, men are the focus of this kind of information in 92.2% of the cases, according to a study presented recently by UC3M professor Clara Sainz de Baranda at the II International Conference on Gender and Communication. "The remaining 5% is neutral information, which is why, in these kinds of topics, like soccer balls, fields, field houses and goals, men appear more often ...

WEST LAFAYETTE, Ind. – Purdue University researchers who developed a new approach to more effectively teach large numbers of engineering students are recommending that the approach be considered for adoption by universities globally. The system, called the Purdue Mechanics Freeform Classroom, allows students to interact with each other and faculty online while accessing hundreds of instructional videos and animations. It was pioneered by Charles Krousgrill, a professor of mechanical engineering, and has been used for more than two years in two mechanical engineering core ...

Hot town, summer in the city — it's nothing new, but ways to handle the heat, humidity, and stormwater haven't changed much since the invention of the sewer system. One solution offered by architectural researchers is known as a "green roof" — a roof covered in living, growing plants to soften the effects of heat, flooding, noise, and stormwater runoff. Elizabeth J. Grant, an assistant professor of architecture and design at Virginia Tech, will present ways for architects to determine the most effective depths of green roofing for stormwater control on Thursday at the ...
