Chinese scientists have developed a solar cell ‘textile’ that can be woven into clothes. It’s flexible enough to be bent more than 200 times, and can collect light on both sides.
 
Scientists have been trying for decades to develop functional, flexible solar cells, because they could be integrated into fabrics and used to coat irregular shapes and surfaces. And now scientists at Fudan University in Shanghai have developed polymer solar cells that are light, flexible, cheap to produce, and thin enough to be used in fabrics.

According to Jon Cartwright at Chemistry World, to create these new solar cells, they figured out that they could interweave microscopic metal wires - coated in an active polymer designed to absorb sunlight - with titanium dioxide nanotubes and a second type of active polymer to form a textile. Together these components work by having the metal wires absorb sunlight and generate electrons and their positive counterparts, known as 'electron holes'. The electrons are then conducted by the titanium dioxide nanotubes, and the electron holes are conducted by the second active polymer. To complete the circuit, says Cartwright, the team painted each side of the textile with transparent, conductive sheets of carbon nanotubes.

Publishing their design in the journal Angewandte Chemie, the team report that the textile has been made to be symmetrical so it can absorb light from either side. It’s also extremely flexible, able to be bent more than 200 times with barely any effect on its overall efficiency. The one downside? It’s only the size of your fingernail. ‘The main difficulties encountered are how to scale up the solar-cell textile while maintaining high energy-conversion efficiencies,” lead researcher Huisheng Peng told Chemistry World.

Independent expert and materials scientist Anyuan Cao from the Department of Advanced Materials and Nanotechnology at Peking University in Beijing commented that while there is certainly potential in the technology, it will not hit the market until it can be upscaled and made more efficient. And that's exactly what Peng and his team are working on now.

Faculty Forum / 10 tips to tame your temper
« on: June 29, 2014, 01:05:26 PM »
1. Think before you speak
In the heat of the moment, it's easy to say something you'll later regret. Take a few moments to collect your thoughts before saying anything — and allow others involved in the situation to do the same.
2. Once you're calm, express your anger
As soon as you're thinking clearly, express your frustration in an assertive but nonconfrontational way. State your concerns and needs clearly and directly, without hurting others or trying to control them.
3. Get some exercise
Physical activity can help reduce stress that can cause you to become angry. If you feel your anger escalating, go for a brisk walk or run, or spend some time doing other enjoyable physical activities.
4. Take a timeout
Timeouts aren't just for kids. Give yourself short breaks during times of the day that tend to be stressful. A few moments of quiet time might help you feel better prepared to handle what's ahead without getting irritated or angry.
5. Identify possible solutions
Instead of focusing on what made you mad, work on resolving the issue at hand. Does your child's messy room drive you crazy? Close the door. Is your partner late for dinner every night? Schedule meals later in the evening — or agree to eat on your own a few times a week. Remind yourself that anger won't fix anything and might only make it worse.
6. Stick with 'I' statements
To avoid criticizing or placing blame — which might only increase tension — use "I" statements to describe the problem. Be respectful and specific. For example, say, "I'm upset that you left the table without offering to help with the dishes," instead of, "You never do any housework."
7. Don't hold a grudge
Forgiveness is a powerful tool. If you allow anger and other negative feelings to crowd out positive feelings, you might find yourself swallowed up by your own bitterness or sense of injustice. But if you can forgive someone who angered you, you might both learn from the situation. It's unrealistic to expect everyone to behave exactly as you want at all times.
8. Use humor to release tension
Lightening up can help diffuse tension. Use humor to help you face what's making you angry and, possibly, any unrealistic expectations you have for how things should go. Avoid sarcasm, though — it can hurt feelings and make things worse.
9. Practice relaxation skills
When your temper flares, put relaxation skills to work. Practice deep-breathing exercises, imagine a relaxing scene, or repeat a calming word or phrase, such as, "Take it easy." You might also listen to music, write in a journal or do a few yoga poses — whatever it takes to encourage relaxation.
10. Know when to seek help
Learning to control anger is a challenge for everyone at times. Consider seeking help for anger issues if your anger seems out of control, causes you to do things you regret or hurts those around you.

2. Beneficial for Diabetics:
According to research conducted by the Yakult Central Institute in Japan, guava leaf tea can effectively lower blood glucose in diabetics by reducing the alpha-glucosidease enzyme activity. Moreover, it prevents the absorption of sucrose and maltose by the body, thereby lowering blood sugar levels. Drinking guava leaf tea for 12 weeks lowers the blood sugar levels without increasing insulin production.
3. Lower Cholesterol:
Research has proved that drinking guava leaf tea for 3 months can lead to reduction in LDL or bad cholesterol and triglycerides without any adverse effect on good cholesterol. Besides, the guava leaves are a great liver tonic.
4. Treatment of Diarrhea and Dysentery:
Guava leaves are herbal remedy for diarrhea and dysentery. For treating diarrhea, boil 30 grams of guava leaves with a handful of rice flour in 1-2 glasses of water and drink this concoction twice a day. In case of dysentery, cut the roots and leaves of guava plant and boil them for 20 minutes at a temperature of 90 degrees Celsius. Strain the water and drink in moderation until relieved.
5. Aids in Digestion:
Guava leaf tea aids in digestion by stimulating digestive enzyme production. The powerful antibacterial agents kill bacteria in the lining of the gut and stop proliferation of toxic enzymes by bacteria. Guava leaves are particularly beneficial in case of food poisoning as well as soothing, vomiting and nausea. To relieve stomach ache, boil 8 pieces of guava leaves in 1.5 liters of water and drink thrice a day.
6. Treatment of Bronchitis:
Guava leaf tea is effective in treating bronchitis by opening up the lungs, loosening mucus and soothing coughs.
7. Treatment of Toothaches, Sore Throats and Gum Disease:
Due to their anti-inflammatory qualities, fresh guava leaves can relieve tooth ache, heal gum and mouth sores and treat sore throats when used for gargling. The antibacterial agent in these leaves protect the teeth and gums and therefore, guava leaves are used as an ingredient in toothpastes and mouth fresheners. Guava leaves can even be made into a natural paste at home for brushing the teeth and gums.
8. Beneficial in Dengue Fever:
Guava leaves are considered a natural remedy for dengue fever. This is because guava leaf extract can increase the number of platelets in the blood and is not toxic at all. For this purpose 9 pieces of guava leaves should be boiled in 5 cups of water until 3 cups of water is left. After straining and cooling, a cup of this concoction should be given to the patient thrice a day.
9. Prostate Cancer:
Guava leaves can be beneficial in case of prostate cancer and enlargement.

Faculty Forum / Surprising Health Benefits of Watermelon
« on: May 24, 2014, 11:15:26 AM »
Summer is the time to indulge in fresh, succulent juicy melon when they are in season and deliver an array of nutrients, vitamin and minerals. It is also incredibly hydrating (up to 92% water!) and is naturally low-fat. Make this melon a part of your daily diet and you will reap amazing benefits that range from improving cardiovascular health to nourishing your eyes and revving up your immune system.
Cardiovascular & Bone Health
The lycopene in watermelon is especially important for our cardiovascular health and is now being recognized as an important factor in promoting bone health. Consuming large amounts of watermelon has also been correlated with improved cardiovascular function because it improves blood flow via vasodilation (relaxation of blood pressure). Dietary lycopene (from foods like watermelon or tomatoes) reduces oxidative stress which normally reduces the activity of osteoblasts and osteoclasts (the two major bone cells involved in the pathogenesis of osteoporosis) – this means stronger bones for those consuming lycopene-rich foods. Watermelon is also rich in potassium which helps to retain calcium in your body, resulting in stronger bones and joints.
Reduces Body Fat
The citrulline in watermelon has been shown to reduce the accumulation of fat in our fat cells. Citrulline is an amino acid which converts into arginine with help from the kidneys. When our bodies absorb citrulline it can take the step of converting into arginine if so required. Citrulline, when consumed, has the ability to (through a series of steps) block the activity of TNAP (tissue-nonspecific alkaline phosphatase) which makes our fat cells create less fat, and thus helps prevent over-accumulation of body fat.
Anti-inflammatory & Antioxidant Support
Watermelon is rich in phenolic compounds like flavonoids, carotenoids, and triterpenoids. The carotenoid lycopene in watermelon is particularly beneficial in reducing inflammation and neutralizing free radicals. The tripterpenoid cucurbitacin E is also present in watermelon, which provides anti-inflammatory support by blocking activity of cyclo-oxygenase enzymes which normally lead to increased inflammatory support. Make sure you pick ripe watermelons, because they contain higher amounts of these beneficial phenolic compounds.
Diuretic & Kidney Support
Watermelon is a natural diuretic which helps increase the flow of urine, but does not strain the kidneys (unlike alcohol and caffeine). Watermelons help the liver process ammonia (waste from protein digestion) which eases strain on the kidneys while getting rid of excess fluids.
Muscle & Nerve Support
Rich in potassium, watermelon is a great natural electrolyte and thus helps regulate the action of nerves and muscles in our body. Potassium determines the degree and frequency with which our muscles contract, and controls the excitation of nerves in our body.
Alkaline-forming
Watermelons have an alkaline-forming effect in the body when fully ripe. Eating lots of alkaline-forming foods (fresh, ripe, fruit and vegetables) can help reduce your risk of developing disease and illness caused by a high-acid diet (namely, meat, eggs and dairy).
Improves Eye Health
Watermelon is a wonderful source of beta-carotene (that rich red hue of watermelon = beta carotene) which is converted in the body to vitamin A. It helps produce the pigments in the retina of the eye and protects against age-related macular degeneration as well as prevents night blindness. Vitamin A also maintains healthy skin, teeth, skeletal and soft tissue, and mucus membranes.
Immune Support, Wound Healing & Prevents Cell Damage
The vitamin C content in watermelon is astoundingly high. Vitamin C is great at improving our immune system by maintaining the redox integrity of cells and thereby protecting them from reactive oxygen species (which damages our cells and DNA). The role of vitamin C in healing wounds has also been observed in numerous studies because it is essential to the formation of new connective tissue. The enzymes involved in forming collagen (the main component of wound healing) cannot function without vitamin C. If you are suffering from any slow-healing wounds, up your intake of vitamin C heavy fruit

কোমড়ের চারিদিকে ফুলেফেপে থাকা চর্বিগুলো সরাতে চান। পেতে চান মেদভুড়ি থেকে মু্ক্তি। তাহলে- নতুন গবেষণার পর বিজ্ঞানীরা কি বলছেন শুনুন-
‘ভরপেট নাস্তা আর দুপুরে পেট ভরে খেলে ওজন নিয়ন্ত্রণ আর ব্লাড সুগার কমবে। দিনে ছয়বার অল্প অল্প খাবার খাওয়ার চেয়ে ভালো কাজ করবে খাবারের এই নতুন রুটিন।
গবেষণায় দেখা গেছে, সারাদিন অল্প অল্প করে খাবার খাওয়ার চেয়ে পেটপুরে দুবেলা খাবার খাওয়াই ভালো। এতে ডায়াবেটিস যেমন নিয়ন্ত্রণে থাকে তেমনি শরীর হালকা-পাতলাও থাকে। আর কেবল তাই না, এভাবে খাবারের রোটিন চালিয়ে যেতে পারলে বৃদ্ধ বয়সেও শরীর-স্বাস্থ্য ভালো থাকে।
এই  তথ্য দিয়ে গবেষকরা আবারও সেই পুরোনো দিনের কথায় ফিরে গেলেন- সকালে নাস্তা করো রাজার হালে, দুপুরের থাও রাজপুত্রের মতো, রাতের খাবার ভিখিরির মতো।
এ মাসের গোড়ার দিকে অারেক গবেষণায় দেখানো হয়েছিলো, সারাদিনে অল্প অল্প করে খাওয়ার চেয়ে দিনে তিনবার ভরপেট খেয়ে নেওয়া ভালো। তারই ধারাবাহিকতায় নতুন এই গবেষণায় অবশ্য বলা হচ্ছে- দিনে তিন নয় দুইবার। আর তা সকাল ও দুপুরে।
ডাচ গবেষকরা দেখেছেন, দিনে বিভিন্ন সময়ে উচ্চ-চর্বি ও শর্করাযুক্ত খাবার খেলে তা পেটের চারিদিকে পরিধি বাড়ায় তেমনি লিভারেও কোলেসস্টরেল জমায়। তবে বেশি খাবার খেলে তাতে এ সমস্যা হয় না।
চেক রিপাবলিকের একটি গবেষক দল সবশেষ ৫৪ জন ৩০ থেকে ৭০ বছর বয়সী ডায়াবেটিস রোগীর ওপর গবেষণাটি চালান। তারা দুই ধরনের ডায়াবেটিক রোগীকে বেছে নিয়েছেন। যাদের একটি দল সাধারণ রোগী যারা নিয়মিত খাদ্যাভ্যাস নিয়ন্ত্রণ করেন।
গবেষকরা এই দলটিকে প্রতিদিন দুটি ডায়েটের একটি অনুসরণ করে যেতে বললেন।
২৭ জনের একটি গ্রুপকে দিন ৬বার কম খাবার গ্রহণের হিসেবে খাবার দেওয়া হলো। আর অপর ২৭ জনকে সকালে ও দুপুরে ভারী খাবার দেওয় হলো। এভাবে চললো ১২ সপ্তাহ।
ডায়াবেটোলোজিয়ায় প্রকাশিত প্রতিবেদনে বলা হয়েছে- এর মধ্য দিয়ে উভয় পক্ষের রোগীরাই তাদের ওজন হারিয়েছেন। কিন্তু দিনে যারা দুবার ভরপেট খাবার খেয়েছেন তাদের ওজন অপেক্ষাকৃত বেশি কমেছে।
যারা দিনে দুবার খেয়েছেন তাদের ওজন কমেছে ৩.৭ কেজি আর যারা দিনে অল্প করে ছয় বার খেয়েছেন তাদের কমেছে ২.৩ কেজি।
লিভারের চর্বিও উভয় পক্ষের কমেছে। ক্নিতু বেশি খাবার যারা খেয়েছেন তাদের কমার হার অপেক্ষাকৃত বেশি।
তবে বিষয়টিতে চূড়ান্ত সিদ্ধান্তে পৌঁছার আগে আরও গবেষণার প্রয়োজন বলেই মত সংশ্লিষ্টদের।

Faculty Sections / Amazing Top 12 Benefits of Aloe Vera
« on: May 21, 2014, 05:26:20 PM »
Among various health benefits of Aloe Vera, top 12 are listed below:

1.  Aloe Vera Is High in Vitamins & Minerals:
Aloe Vera contains many vitamins including A, C, E, folic acid, choline, B1, B2, B3 (niacin), B6. Aloe Vera is also one of the few plants that contains vitamin B12.
Some of the 20 minerals found in Aloe Vera include: calcium, magnesium, zinc, chromium, selenium, sodium, iron, potassium, copper, manganese.

2. Aloe Vera is High in Amino Acids & Fatty Acids
Amino acids are the building blocks of protein. There are about 22 amino acids that are necessary for the human body and it is said that 8 of these are essential. Estimates of the amino acids found in aloe range from 18-20 amino acids, with all 8 essential amino acids.
Alove Vera also includes quite an impressive range of fatty acids. Aloe contains three plant sterols, which are important fatty acids- HCL cholesterol (which lowers fats in the blood), campesterol, and B-sitosterol. All are helpful in reducing symptoms of allergies and acid indigestion. Other fatty acids include linoleic, linolenic, myristic, caprylic, oleic, palmitic, and  stearic.

3. Aloe Vera is an Adaptogen
Aloe Vera is a well-known adaptogen. An adaptogen is something that boosts the body’s natural ability to adapt to external changes and resist illness. It is thought that aloe’s power as an adaptogen balances the body’s system, stimulating the defense and adaptive mechanisms of the body. This allows you an increased ability to cope with stress (physical, emotional and environmental stress like pollution)

4. Aloe Helps with Digestion
Poor digestion is related to many diseases. A properly functioning digestive tract is one of the keys and foundations of health. Aloe is known to soothe and cleanse the digestive tract and help improve digestion. The interesting thing about taking aloe internally is that, because it is an adaptogen, it helps with either constipation or diarrhea, helping to regulate your elimination cycles in whatever way you need.  It’s been a great remedy for people with problems such as irritable bowel syndrome as well as acid reflux. Aloe also helps to decrease the amount of unfriendly bacteria and in our gut keeping your healthy intestinal flora in balance. Aloe is also a vermifuge, which means it helps to rid the body of intestinal worms.

5. Aloe Helps in Detoxification
Aloe Vera is a gelatinous plant food, just like seaweeds and chia. The main benefit to consuming gelatinous plant foods in your diet is that these gels move through the intestinal tract absorbing toxins along the way and get eliminated through the colon. This will help the proper elimination of waste from your body and help the detoxification of your body.

6.  Aloe Alkalizes the Body
Disease cannot manifest in an alkaline environment. Most people are living and subsisting on mostly acidic foods. For great health, remember the 80/20 rule – 80% alkaline forming foods and 20% acidic. Aloe vera is an alkaline forming food. It alkalizes the body, helping to balance overly acidic dietary habits.

7. Cardiovascular Health
There haven’t been a lot of studies conducted in this but there has been some research to show that Aloe Vera extract injected into the blood, greatly multiplies the oxygen transportation and diffusion capabilities of the red blood cells.
According to a study published in the 2000 issue of the British Medical Journal, beta sitosterol helps to lower cholesterol. By regulating blood pressure, improving circulation and oxidation of the blood, lowering cholesterol, and making blood less sticky, Aloe Vera juice may be able to help lower the risk of heart disease.

8. Aloe Helps Boost the Immune System
I think given the stresses of our daily lives, everyone can use a boost to their immune systems. The polysaccharides in aloe vera juice stimulate macrophages, which are the white blood cells of your immune system that fight against viruses.
Aloe is also an immune enhancer because of its high level of anti-oxidants, which help combat the unstable compounds known as free-radicals, contributing to the aging process. (Free radicals are a bi-product of life itself, it is a naturally occurring process but we can overload ourselves with unnecessary free-radicals by living an unhealthy lifestyle) Aloe is also an antipyretic which means it used to reduce or prevent fever.

9. Aloe Vera is Great for the Skin
Because of aloe’s well-known healing properties for the skin, aloe is one of the primary compounds used in the cosmetic industry. It is a known vulnerary, (meaning it helps heal wounds) and is great for applying topically to burns, abrasions, psoriasis and even to bug bites. Aloe acts as an analgesic, acting to help relieve pain of wounds. It’s feels especially good to cut a stem of aloe, place it in the fridge and rub it on sun burnt skin – the immediate soothing effect feels like an absolute lifesaver. Aloe is also an antipruritic: A substance that relieves or prevents itching. Aloe Vera is an astringent: which causes the contraction of body tissues, typically used to reduce bleeding from minor abrasions.
Due to aloe’s high water content (over 99% water) it is a great way to hydrate, moisturize and rejuvenate the skin and fits within my general guideline: “Don’t put anything on your skin that you wouldn’t eat!” Aloe increases the elasticity of the skin making it more flexible through collagen and elastin repair. Aloe is an emollient, helping to soften and soothe the skin. It helps supply oxygen to the skin cells, increasing the strength and synthesis of skin tissue and induces improved blood flow to the skin through capillary dilation.

10. Disinfectant, Anti-biotic, Anti-microbial, Germicidal, Anti-bacterial, Anti-septic, Anti-fungal & Anti-viral:
Wow, I think that covers all anti- bases. Okay, I admit, that was just a sneaky way to add in another 8 good reasons why you should keep Aloe Vera handy and incorporate it into your lifestyle. Aloe Vera’s active ingredients are sulphur, lupeol, salicylic acid, cinnamic acid, urea nitrogen and phenol which are substances that prevent the growth of disease-causing microorganisms and act as a team to provide antimicrobial activity thus eliminating many internal and external infections, also active against bacteria. It also helps to treat fungal and viral infections.

11. Aloe Helps Reduce Inflammation

Aloe Vera contains 12 substances, including B-sisterole, which can help to slow down or inhibit inflammation.  This may be able to help with painful joints due to stiffness and help improve joint flexibility.

12. Weight Loss – A Secondary effect
Improving your digestion, and detoxifying your will have a secondary effect in promoting weight loss because when we start to improve our digestion we naturally eliminate more efficiently, which is a primary way they we detoxify – through our bowels. This will lighten our toxic load on the body and will give us more energy.

Chandra Bahadur Dangi (born on November 30, 1939 in Nepal) is the shortest man in the world, measuring 0.546 m (1 ft 9 in). Dangi is a primordial dwarf. He broke the record of Gul Mohammed (1957-1997), the shortest adult human whose height was 0.57 m (1 ft 10 in).

Jyoti Amge (born 16 December 1993), a resident of Nagpur, India, is the world's smallest living woman according to the Limca Book of Records and Guinness Book of Records. On December 16, 2011 ‒ Amge's 18th birthday, she was officially declared the world's smallest woman by Guinness Book of Records with a height of 62.8 cm (2 ft 0.6 in). Her restricted height is due to a growth anomaly called achondroplasia.

Both of them are record holders from the new Guinness World Records 2014 book.

Professor Jane Medford and her team developed plants that will turn white when exposed to explosives and environmental pollutants.  Professor June and one of her team stand beside plants they have taught to change colour when in the presence of explosives

How it works:
The receptor proteins in plant DNA respond to threatening stimuli by releasing chemicals to thicken the leaf cuticle, changing its colour. Scientists manipulated this to respond to explosive chemicals.
 
The following picture is at an airport. A terrorist rolls through the sliding doors of a terminal with a bomb packed into his luggage (or his underwear). All of a sudden, the leafy, verdant gardenscape ringing the gates goes white as a sheet. That’s the proteins inside the plants telling authorities that they’ve picked up the chemical trace of the guy’s arsenal.
