When Nrf2 is exposed to threats to the cell's health it oscillates faster and activates an increase in the cell's defence mechanism including raising the levels of antioxidant.
The researchers from the University's Warwick Medical school successfully increased the speed of Nrf2's movement by artificially introducing health beneficial substances--potential components of new superfoods The beneficial substances comprise broccoli-derived sulforaphane and quercetin
which are currently being trialled to decrease risk of developing diabetes and heart disease. Published by Antioxidants
The health benefit of Nrf2 oscillating at a fast speed is that surveillance of cell health is increased
when cells are under threat. By understanding how this process works and increasing Nrf2's speed without putting cells under threat new strategies for design of healthier foods
and improved drugs can be devised. Current designs may have selected substances with suboptimal if not poor health benefits in some cases.

Habitat loss and fragmentation due to development are the largest threats. These are also significant threats in the nation's grasslands where the report notes a decline in breeding birds like the eastern meadowlark and the bobolink of nearly 40 percent since 1968.

#Sleeping on animal fur in infancy found to reduce risk of asthmasleeping on animal fur in the first three months of life might reduce the risk of asthma in later childhood a new study has found.
and fur could have a protective effect against asthma and allergies. Previous studies have suggested that exposure to a wider range of environments from a young age could be protective against asthma and allergies.
These findings have not been confirmed conclusively in urban settings. In this new study researchers investigated children from a city environment who had been exposed to animal skin by sleeping on the material shortly after birth.
The results showed that sleeping on animal skin was associated with a reduced risk of a number of factors connected to asthma.

#Pesticide risk assessments seen as biased, experts advisein the October issue of Bioscience a group of ecotoxicologists argue that the US Environmental protection agency's (USEPA) current practices for evaluating pesticide safety are inadequate
In their article Michelle Boone of Miami University and her colleagues note that most pesticide toxicity tests used in risk assessments are conducted by pesticide manufacturers themselves
which the authors believe can result in untenable conflicts of interest. Moreover rigid inclusion criteria often mean that potentially relevant studies are barred from the USEPA's assessment process.
The researchers also cite other problems with USEPA risk assessment practices including inconsistent application of criteria among taxonomic groups and an overreliance on laboratory studies among others.
The authors conclude that the risk assessment process can and should be improved so that decisions are made with the best available data with an evidence-based approach.
This separation would serve to reduce concerns over conflicts of interest. In addition they recommend a wider use of all available research--particularly field studies

#Fruit consumption cuts cardiovascular disease risk by up to 40 percentdaily fruit consumption cuts the risk of cardiovascular disease (CVD) by up to 40%according to research presented at ESC Congress by Dr Huaidong
The findings from the seven year follow-up study of nearly 0. 5 million people in the China Kadoorie Biobank found that the more fruit people ate the more their risk of CVD declined.
Improving diet and lifestyle is critical for CVD risk reduction in the general population but the large majority of this evidence has come from western countries and hardly any from China.
and risk factors we have conducted the first large prospective study on the association of fruit with subtypes of stroke in Chinese adults from both rural and urban areas.
and the risk of CVD (see figure). Dr Du said: Our data clearly shows that eating fresh fruit can reduce the risk of cardiovascular disease including ischaemic heart disease and stroke (particularly haemorrhagic stroke.
And not only that the more fruit you eat the more your CVD risk goes down.
We also found that the beneficial effect of fruit on the risk of CVD was independent of its impact on baseline BP.
They found that compared to those who never ate fruit daily consumers of fruit cut their overall risk of death by 32%.
%They also reduced their risks of dying from IHD by 27%and from stroke by around 40%.

and leafy vegetables and fruits have a lower risk of developing diabetes even when they don't lose weight Dr. Hamdy says.
Foods such as oat cereal yogurt and dairy products green leafy vegetables grapes apples blueberries and walnuts were associated with reduced diabetes risk.
Drinking coffee and even decaffeinated coffee were associated also with lower type 2 diabetes risk. Participants who followed a Mediterranean eating plan--without restricting calories--showed a greater improvement in glycemic control
Foods associated with a higher risk of diabetes include red and processed meat sugar-sweetened beverages alcohol in excess quantities and refined grains such as white flour.
Current evidence shows that some fats such as those from red and processed meats are associated with higher cardiovascular risk
while other fats such as those from vegetable oils and nuts are associated with lower risk. The Joslin nutritional guidelines for diabetes recommend a diet with relatively high amounts of healthy fats and protein but moderately low amounts of carbohydrates.
The laboratory recreation of a fungus-derived antibiotic viridicatumtoxin B may someday help bolster the fight against bacteria that evolve resistance to treatments in hospitals and clinics around the world.

Here local farmers see cheetahs as a potential threat for their cattle. The conflict is an old one:
wherever there are carnivorous wild animals farmers are concerned about their livestock. In Namibia the concern refers to the possible threat from cheetahs on cattle.

This study published in the scientific online journal PLOS ONE will contribute to the protection of cheetahs--but not in adversity to the interest of the farmers.

#Delivery by drone: New algorithm lets drones monitor their own health during long package-delivery missionsin the near future the package that you ordered online may be deposited at your doorstep by a drone:
Last December online retailer Amazon announced plans to explore drone-based delivery suggesting that fleets of flying robots might serve as autonomous messengers that shuttle packages to customers within 30 minutes of an order.
To ensure safe timely and accurate delivery drones would need to deal with a degree of uncertainty in responding to factors such as high winds sensor measurement errors or drops in fuel.
But such what-if planning typically requires massive computation which can be difficult to perform on the fly.
Now MIT researchers have come up with a two-pronged approach that significantly reduces the computation associated with lengthy delivery missions.
In simulations involving multiple deliveries under various environmental conditions the researchers found that their drones delivered as many packages as those that lacked health-monitoring algorithms--but with far fewer failures or breakdowns.
With something like package delivery which needs to be done persistently over hours you need to take into account the health of the system says Ali-akbar Agha-mohammadi a postdoc in MIT's Department of Aeronautics and Astronautics.
As Agha-mohammadi explains it MDP is the process of reasoning about the future to determine the best sequence of policies to minimize risk.
