Will future population growth be limited by freshwater availability?

2015-03-16
(Press-News.org) The global human population is growing faster than the water supply. Investigators recently analyzed various models and trends to assess both optimistic and pessimistic projections of future water use and shortages.

"Historically, water supply has grown through alternating periods of rapid growth and stagnation, and we now seem to be entering a new period of stagnation while the population continues to grow," said Dr. Anthony Parolari, lead author of the WIREs Water article. "To avoid water scarcity from this point forward, the alternatives include further water supply improvements through technological innovation, or we may need to consider more seriously the concept of a sustainable rate of global water use."

Milk protein comparison unveils nutritional gems for developing babies

Milk protein comparison unveils nutritional gems for developing babies
2015-03-16
Human babies appear to need more of a nutritional boost from breast-milk proteins than do infants of one of their closest primate relatives, suggests a study comparing human milk with the milk of rhesus macaque monkeys. The research team, led by the University of California, Davis, came to this conclusion after developing a new technique for comparing the proteome -- all detectable proteins -- of human milk with the proteome of the rhesus macaque monkey. The researchers expect the findings will provide a better understanding of human breast-milk composition and identify ...

How does prison time affect relationships?

2015-03-16
A new study highlights the complicated spillover effects of incarceration on the quality of relationships. Although paternal incarceration in the past 2 years was mostly inconsequential for fathers' reports of relationship quality, mothers connected to these recently incarcerated men reported lower overall relationship quality, lower supportiveness, and greater physical abuse. Surprisingly, current paternal incarceration was positively associated with some indicators of relationship quality. "The fact that current and recent paternal incarceration have countervailing ...

Even high-risk patients can benefit from aortic aneurysm repair

2015-03-16
MAYWOOD, Ill. (March 16, 20125) - Minimally invasive surgery can prevent a fatal rupture of an abdominal aortic aneurysm. And now a new study has found the procedure can extend lives even in patients who are at high risk for surgery due to such risk factors such as advanced age, diabetes, smoking and kidney disease. However, not all high-risk patients - especially those undergoing cancer treatment -- benefit, the study found. The decision on whether to perform the procedure "should be individualized, depending on the number and severity of risk factors," reported corresponding ...

Genetically manipulating plants can reduce their water needs

2015-03-16
Improving the efficiency by which crops use water is a critical priority for regions facing increased drought or diminished groundwater resources. Now researchers have found that this can be achieved by genetically altering plants' stomata, the tiny openings on the leaf surface through which carbon dioxide is absorbed and water evaporates. "We now have genetic tools to pre-adapt crops to future, drier climates. The goal here is to maintain or improve productivity with less water," said Dr. Peter Franks, lead author of the New Phytologist study. INFORMATION: ...

Predicting prostate cancer

2015-03-16
EVANSTON, Ill. --- A Northwestern University-led study in the emerging field of nanocytology could one day help men make better decisions about whether or not to undergo aggressive prostate cancer treatments. Technology developed by Northwestern University researchers may help solve that quandary by allowing physicians to identify which nascent cancers are likely to escalate into potentially life-threatening malignancies and which ones will remain "indolent," or non-aggressive. The prostate-specific antigen (PSA) test was once the recommended screening tool for detecting ...

New Notre Dame paper examines social effects on the gut microbiome of wild baboons

2015-03-16
A new study led by Elizabeth Archie, Clare Boothe Luce Asistant Professor of Biology at the University of Notre Dame, has found that social interactions have direct effects on the gut microbiome. Archie points out that most, if not all, animals have a gut microbiome -- an incredibly diverse "rainforest" of bacteria that lives in the intestine and helps animals digest food, make vitamins and fight disease. The new study revealed that baboons that had closer social bonds had more similar gut bacteria than animals with weaker social ties. "In the last few years, scientists ...

NASA sees Tropical Cyclone Nathan moving south and strengthening

NASA sees Tropical Cyclone Nathan moving south and strengthening
2015-03-16
The MODIS instrument aboard NASA's Terra satellite captured a visible image of Tropical Cyclone Nathan east of the Queensland coast on March 16 at 0:00 UTC. The image showed a rounded circulation with bands of thunderstorms wrapping into the center of circulation. At 0900 UTC (5 a.m. EDT), Tropical cyclone Nathan's maximum sustained winds were near 55 knots (63.2 mph/102 kph) and the storm was consolidating and organizing. The Joint Typhoon Warning Center (JTWC) forecasters expect Nathan to strengthen to 70 knots in two days. Nathan was centered near 14.3 south latitude ...

Products that reversibly change shape with temperature may revolutionize medicine

2015-03-16
New research highlights the capability of reversible shape-memory polymers to change their shape when heated to body temperature and then switch back to their original shape when cooled to room temperature. The technology could have applications in temperature intervals relevant for biomedical applications--for example, devices for external short-term applications such as bandages or temporary fixation parts, where the product would be activated upon exposure to human body temperature. The technology could also be used for home-care products to support the daily life ...

Symmetry matters in graphene growth

Symmetry matters in graphene growth
2015-03-16
What lies beneath growing islands of graphene is important to its properties, according to a new study led by Rice University. Scientists at Rice analyzed patterns of graphene - a single-atom-thick sheet of carbon - grown in a furnace via chemical vapor deposition. They discovered that the geometric relationship between graphene and the substrate, the underlying material on which carbon assembles atom by atom, determines how the island shapes emerge. The study led by Rice theoretical physicist Boris Yakobson and postdoctoral researcher Vasilii Artyukhov shows how the ...

Available treatments for hepatitis C virus cost-effective when initiated early

2015-03-16
New treatments for hepatitis C virus (HCV) may be highly effective but are associated with substantial costs that may compel clinicians and patients to consider delaying treatment. However, a new study shows that immediate treatment of HCV-infected patients with moderate or advanced liver scarring is cost-effective. Immediate treatment of patients with minimal or no scarring can be cost-effective as well, particularly when lower treatment costs are assumed. "The devastating effects of hepatitis C continue to threaten the health of many Americans, with baby boomers at ...
