A new HIV test able to deliver results visible to the naked eye could greatly benefit impoverished countries that lack sophisticated laboratories. The test involves adding serum from a blood sample to a solution of gold nanoparticles that react in a specific way when exposed to the HIV biomarker p24. If p24 is present, the nanoparticles will gather in an irregular pattern that turns the solution blue, while the absence of p24 will cause the nanoparticles to separate into ball...

When we face someone's irritability we usually say that the person got up on the wrong side of the bed. This condition is familiar to many people. And who is to blame? In most cases an alarm is to blame. The alarm clock came into our lives a long time ago. Most of modern people feel helpless without the alarm. But experts say that if a person cannot do without the alarm then he/she has a wrong sleep: there are problems with either the duration or quality of sleep. These...

Three main things are needed for a good-looking head of hair - good health, the right attention to cleanliness, and caution when using cosmetic treatments. 1. Adequate Diet Hair growth depends on an adequate diet. A widespread diet problem which causes loss of hair is iron deficiency Anaemia. The cause is too little iron in blood, brought on by a diet containing too little meat, eggs, cereals or peas and beans. Fresh fruits and vegetables are also needed to provide...

Many people try to cope with heartburn with the help of baking soda. Soda helps to get rid of the pain only for a while. If constantly used soda affects the mucous coat of stomach, violates the acid-base balance and can assist with disease progress. Prolonged heartburn can cause serious complications and even precancerous condition. People, who rarely suffer from heartburn, can remove the pain attack after drinking half a glass of alkaline non-carbonated water or milk. Decoctions...

House call by a child sleep adviser is a new service popular among young American parents. The help of such consultants is not cheap ($200 - $800), which is practically comparable to the cost of business consultants. The principle of the sleep consultant is the same - he analyzes the causes of anxiety, various stressful situations and develops a plan how to improve them, teach parents the right approach to communicating with the child. Consultant's advice is a simple practical...

This idea can help blind people to gain partial eyesight. There will be a microchip to be implanted onto a patient's eyeball. The patient will wear special glasses with a camera that transmits images to the microchip and fires an electrode under the retina, stimulating the optic nerve.

Why not create small pacemakers that can be inserted by a catheter, eliminating the need for invasive surgery? The pacemaker is supposed to be injected under the clavicle, where intercardiac leads then carry surges of electricity to the heart. The electricity will be sent exactly where it will needed, resulting in greater efficiency and less power requirements. Since the procedure is less invasive, it will be a simpler procedure to learn.

Monitoring fetal health in remote areas could become easier with a portable and inexpensive wireless fetal monitor. The device will able to measure fetal heart rate and the force of contractions, and process the information with a Bluetooth transmitter and a smart phone device with custom software. The new wireless aspect will eliminate the need for the large bedside date processing machine. The device could be used to monitor pregnant women in rural locations.

Why not create a system that will allow the blind to "see" their surroundings through the use of sound. The system will use sunglasses with built-in micro video cameras, a computer, and a pair of headphones. The cameras will analyze the space in front of them and create a 3D model in which various surfaces will be assigned sounds to be played back through the headphones. Blind users will be able to decipher the sounds and "hear" the space around them, which their brains will turn...

The idea is to develop implantable medical devices powered by blood sugar and oxygen, eliminating the need for batteries and wires. The implantable glucose fuel cells are supposed to work on the basis of noble metal catalysts such as platinum, which is very stable and can be sterilized. Equipping systems with the fuel cells could enable them to be powered by a continuous electrochemical reaction between the glucose and the oxygen from the tissue fluid. Typical pacemaker...
