#Mangroves protecting corals from climate changecertain types of corals invertebrates of the sea that have been On earth for millions of years appear to have found a way to survive some of their most destructive threats by attaching to and growing under mangrove roots.
Scientists with the U s. Geological Survey and Eckerd College recently published research on a newly discovered refuge for reef-building corals in mangrove habitats of the U s. Virgin islands.
and face many threats such as coastal pollution dredging and disease. However some of their most widespread threats involve warming ocean temperatures solar radiation and increased ocean acidification.
It is from these threats that corals are finding refuge under the red mangroves of Hurricane Hole.

#Herbivores play important role in protecting habitats from invasive speciesherbivores (species that eat plants; e g. caterpillars) consume more nonnative (introduced from other places) oak leaf material in areas with diverse native plant communities than in less diverse communities.
As the introduction of nonnative species increases protection of intact plant communities and their associated herbivores may become critical to guarding against the nonnative species invaders.

Plants use defenses against pests, but they dont always worksugars are usually known as energy storage units in plants
Grasses and crops such as maize attach sugars to chemical defenses called benzoxazinoids to protect themselves from being poisoned by their own protective agents.
However many insects have become adapted to plant defenses and can feed on plant tissues containing toxins or deterrents without the expected negative effects.
Insects overcome plant defenses by the rapid excretion sequestration or detoxification of toxic substances Not only have contributed such adaptations to the vast diversification of insects in the course of evolution they also support the success of agricultural pests specialized on certain crop plants that jeopardize crop yields every year.
The increasing resistance of pest insects to Bt is another reason to look deeper into the natural insect adaptations against plant defenses.

A majority of mothers had a history of CMV infection prior to delivery (CMV sero-prevalence of 76.2 percent.
Previously the risk of CMV infection from blood transfusion of seronegative or leukoreduced transfusions was estimated to be 1 to 3 percent.
Therefore we believe that this is the safest approach to reduce the risk of CMV infection when giving transfusions to VLBW infants.
The American Academy of Pediatrics currently states that the value of routinely feeding breast milk from CMV seropositive mothers to preterm infants outweighs the risks of clinical disease from CMV.
Alternative approaches to prevent breast milk transmission of CMV say the authors could include routine CMV-serologic testing of pregnant mothers to enable counseling regarding the risk of infection;
closer surveillance of infants with CMV-positive mothers; and pasteurization of breast milk until a corrected gestational age of 34 weeks (as recommended by the Austrian Society of Pediatrics.
#Healthy lifestyle choices may dramatically reduce risk of heart attack in menfollowing a healthy lifestyle including maintaining a healthy weight
Men in the study with the lowest risk were walked nonsmokers or cycled for at least 40 minutes per day exercised at least one hour per week had a waist circumference below 95 centimeters consumed moderate amounts of alcohol
The researchers found a clear reduction in risk for heart attack for each individual lifestyle factor the participants practiced.
For instance having a low-risk diet together with a moderate alcohol consumption led to an estimated 35 percent lower risk of heart attack compared to the high-risk group those who practice none of the low-risk factors.
and having a low amount of abdominal fat had 86 percent lower risk. Researchers found similar results in men with hypertension and high cholesterol levels.
What is surprising is how drastically the risk dropped due to these factors. According to the authors less than 2 percent of the American population conforms to
and promoting low-risk lifestyle choices. Even in those who take medication an additional reduction in risk for chronic heart disease has been observed in those with a healthy lifestyle.
It is important to note that these lifestyle behaviors are modifiable and changing from high-risk to low-risk behaviors can have great impact on cardiovascular health Akesson said.

#Mown grass smell sends SOS for help in resisting insect attacksthe smell of cut grass in recent years has been identified as the plantâ##s way of signalling distress
but new research says the aroma also summons beneficial insects to the rescue. â#oewhen there is need for protection the plant signals the environment via the emission of volatile organic compounds which are recognized as a feeding queue for parasitic wasps to come to the plant that is being eaten
which involves activation of defenses against insects on the plant. Then this molecule since it is a volatile attracts parasitic wasps.

And their studies suggest that these methods could be as efficient in protecting crops as using chemical based pesticides.
Commonly farmers use plant protection products like insecticides or plant growing regulators to protect their crops against pests and diseases.
But used in a wrong way pesticides can pose a risk to humans and the surrounding environment.
Small serving beneficial, large not necessarya daily small serve of dairy food may reduce the risk of heart disease or stroke even in communities where such foods have not traditionally formed part of the diet.
and in particular raise the risk of cancer. The study showed such fears to be unfounded. We observed that increased dairy consumption meant lower risks of mortality from cardiovascular disease especially stroke
but found no significant association with the risk of cancer Professor Wahlqvist said. Milk and other dairy foods are recognised as providing a broad spectrum of nutrients essential for human health.
According to the study findings people only need to eat small amounts to gain the benefits.

Indeed high intakes of red meat and meat products have been shown to increase the risk of T2d.
Nevertheless several epidemiological studies have indicated that a high intake of dairy products may be protective. Subsequently the importance of dietary fat content and food sources of fat remains to be clarified.
In this new study the authors aimed to examine intakes of main dietary fat sources classified according to fat content and their association with risk of developing T2d.
%)was associated with a 15%reduction in risk of developing type 2 diabetes. High-fat fermented milk*consumption also reduced the risk of developing diabetes by 20
%when comparing the highest consumers (180ml/day the top 10%of consumers) with the non-consumers (60%of participants).
In contrast to these findings there was no association found between intakes of low-fat dairy products and risk of developing type 2 diabetes.
High intakes of meat and meat products were regardless of fat content associated with increased risk
but the increased risk was higher for lower fat meats (increased risk of type 2 diabetes for high fat meats 9%for low fat 24%)both referring to the risk
The decreased risk at high intakes of high-fat dairy products but not of low-fat dairy products indicate that dairy fat at least partly explains observed protective associations between dairy intake and T2d.
Meat intake was associated with increased risk of developing diabetes regardless of fat content. She adds:

Study finds important genes in defense responsewhen corn plants come under attack from a pathogen they sometimes respond by killing their own cells near the site of the attack committing cell suicide to thwart further damage from the attacker.
and cellular processes that appear to control this so-called hypersensitive defense response (HR) in corn.
The findings which appear in PLOS Genetics could help researchers build better defense responses in corn and other plants;
The 44 candidate genes appear to be involved in defense response programmed cell death cell wall modification
and a few other responses linked to resisting attack says Dr. Peter Balint-Kurti the paper's corresponding author and a U s. Department of agriculture (USDA) professor who works in NC State's plant pathology and crop science
This mutation causes a corn plant to inappropriately trigger this hypersensitive defense response causing spots on the corn plant as well as stunted growth.
Balint-Kurti said the top candidates made sense as they mostly appear to be linked to defense or disease resistance.
Hopefully this work provides an opening to really characterize this important defense response and learn more about it in other plants.

For example farmers in the United states and Australia have used planting of pest-friendly refuges to delay evolution of insect resistance to genetically engineered corn and cotton.
These genetically modified crops kill certain pests but without refuges the pests quickly adapt. Providing refuges of conventional plants has been especially effective for suppressing resistance in the pink bollworm an invasive pest of cotton.
However Peter Jørgensen also cautions: In many cases decision makers must pay more attention to assuring that long-term benefits of applying these solutions do not come at a short-term cost for some individuals for example from yield loss due to localised effects of pests in a particular year.
By encouraging cost sharing local communities and governments play a crucial role in ensuring that everybody gains from the benefits of using evolutionary biology to realise the long-term goals of sustainable development such as increasing food security protecting biodiversity
