The New Easy Method for a Perfect Smile

There is nothing like a smile filled with white teeth to express joy, contentment and sometimes even embarrassment. There are many products on the market that claim to turn your teeth "pearly white", but most contain harsh whitening chemicals that may also damage tooth enamel, the protective layer of your teeth. The problem is that tooth tartar, the hardened product of minerals from food and saliva that accumulates in plaque around the teeth, cannot be removed with a toothbrush. 

There are many things you can do to avoid making your teeth ever darker. You can avoid smoking and drinking coffee, make sure to chew on both sides, use dental floss religiously and brush your teeth in the EXACT right way - and you'll still find that your teeth continue to get darker with age and do suffer spots and blemishes. Teeth were just not designed to stay white and pearly all your life, at some point they do go through wear and tear, as we use them several times a day (or more) to chew through many types of food, soft and hard, acidic or not. With time, teeth always get darker.


So what can you do when it's already happened and your teeth have become yellowish or yellow? Well, a quick look at the toothpaste aisle and you'll see there are a plethora of toothpastes named "whitening" or "crystal smile" - but can these actually make your teeth white? 

The answer in most cases is a resounding NO. You may use these to lessen the effect of coffee and other materials that stain your teeth, but it will not make the teeth white again nor will it even stop the yellowing effect, only slow it down a bit.

What we found here at Baba is that products that are made specifically to whiten teeth are much better at actually achieving the desired effect. We're not talking about salves and ointments though, those don't work half as well as advertised. No, we're talking about SNOW - the device that has been changing the game of teeth whitening around the world since 2018.

This device takes no effort at all, it's as simple as plugging it in and sitting down. The device goes in your mouth and, using a formula invented by dentists, uses enamel-safe ingredients to whiten your teeth via harmless light that nevertheless whitens your teeth in 20-minute sessions.

What you need to do is put it in your mouth once a day while reading a book or watching your favorite show (or even taking a timed nap!) and continue for a few weeks. As you will see by the people above, it takes about two weeks to go a full shade whiter, and less than a month to get a shocking transformation of your teeth from yellowing to pearly white.

New device to help people with swallowing problems

Here's the good news for the patients suffering from swallowing disorders. Scientists reveal a wearable monitoring device that will make the treatments easier and more affordable.

An associate professor of speech, language, and hearing sciences and an assistant professor of biomedical engineering and mechanical engineering  have founded Curasis LLC to commercialise their wearable technology and move it as quickly as possible to clinics and people with swallowing difficulties.

"We want to provide a reliable, patient-friendly and affordable way to treat the millions of people with swallowing disorders," said the Prof. "Many devices to help these people are expensive, not able to be taken home and not accessible in many rural areas."

The researchers have created a skin-mountable sensor sticker that attaches firmly to the neck area and is connected with small cables to a wireless transmitter unit. The skin-mountable sensor sticker measures and records muscle activity and movement associated with swallowing.

The information is then sent wirelessly by a separate unit clipped on the wearer's shirt to software that stores it for later analysis by a doctor.

Successful completion of a swallow requires the precise coordination of more than 30 pairs of muscles of the head and neck, six pairs of cranial nerves, and complex circuitry in the brainstem and several brain areas.

Any disruption in these pathways can result in severe swallowing disorders.

"Our device is unique in that we specifically created it to work well with the small and intricate muscles associated with swallowing events," Lee said.

"The sensor sticker is stretchable and flexible to work well with the skin and curvilinear head and neck shape, while the connected unit has electronic chips and more rigid components," added the Prof.
The sensor stickers are disposable, designed with inexpensive components and meant to be used about 10 times before they are thrown away.

Revolutionary implant helps paralysed patients walk again

A small group of paraplegic patients have once again been able to take steps after researchers implanted a device to electrically stimulate their spinal cords.

Two separate teams of scientists have revealed for the first time that the technique, together with physical training, has allowed three out of the five individuals treated to walk again after losing all voluntary movement below the site of the injury.

“It is incredible to be able to be in there and actually see them taking their first steps,” said Dr Claudia Angeli of Kentucky Spinal Cord Injury Research Centre at the University of Louisville, and a co-author of one of the studies.

“It is an emotional time for the individual [themselves] because it is something that they have been told they are never going to be able to do again.”

In a study published in the New England Journal of Medicine, Angeli and colleagues report that they implanted an array of 16 electrodes in the lower back of four patients, paralysed after mountain bike or traffic accidents several years before.

The device, originally developed many years ago for pain control, was placed below the site of injury, covering regions that send sensorimotor signals to the legs while a battery was implanted in the abdominal wall, allowing the frequency of the stimulation, its intensity and duration, to be tweaked wirelessly.

Electrical activity produced by muscles in the legs was monitored during the sessions.

The approach – called epidural stimulation – works on the principle that there are still some small signals from the brain that cross the site of the spinal cord injury – even though these are not enough on their own to generate voluntary movement.

“We know the spinal cord has the ability to organise very detailed motor activity,” said Angeli.

“But before the injury it was getting commands from the brain and it was getting information from the environment as well.”

The injury, she said, disrupts this.

“The spinal cord is isolated, it potentially still receives information from the environment, but it is losing the big driver, which was the brain.”

Angeli said that it is thought that when the implanted device is turned on, the resulting electrical stimulation raises the excitability of the spinal cord – in a sense making it more alert.

“It is like it is more aware, it actually can listen to that little whisper from the brain that is still there and it can generate the motor pattern,” said Angeli, adding that training to link movements with these signals is crucial.

All four of the individuals had lost all motor control below the site of the injury, although two had some level of sensation.

After implantation of the device and locomotor training, the latter two were eventually able to walk over ground unassisted.

One was able to walk after 81 sessions of stimulation over 15 weeks, although she had to use a walking frame, while the other was able to walk after 278 sessions over 85 weeks, requiring either parallel bars or holding people’s hands. In total he was able to walk just over 90 metres without a break.

The other two individuals became able to stand and sit independently and one was also able to make some stepping motions on a treadmill when supported – however the other sustained a spontaneous hip fracture after one week of training and only began training again a year later.

A separate paper by researchers from the Mayo clinic in Minnesota and UCLA, published in the journal Nature Medicine, also reports success with the same approach.

The team revealed that after 43 weeks of training with the implant a 29-year-old man, paralysed after a snowmobile accident and left with no sensation or voluntary motion below the injury, could walk without help on a treadmill – holding on to the rails – and across the ground, albeit with a moving frame and a little human help to maintain balance. He did not, however, regain sensation in his legs.

Professor Gregoire Courtine from the EPFL research institute in Switzerland, who was not involved in either study, said he welcomed the research. But he said a key problem was that the current applied to the electrodes was continuous, meaning it can only be of low intensity – which may not result in the “whisper” from the brain being heard loudly enough by the legs.

Courtine said he is working to solve this issue by synchronising the electrical stimulation with intended movements – his previous work in monkeys used brain implants to pick up on movement signals from the brain and send them to the legs, bypassing the site of injury and allowing a greater amplification of the signal to produce more robust muscle activity.

Mike Milner, CEO of the Nicholls Spinal Injury Foundation was also cautious, saying while the research looked promising, the charity supports another approach to tackle spinal injury using special cells taken from a patient’s nose, as well as nerve fibres, to patch the site of the injury.

“We are looking for not only a natural, or biological, cure for paralysis – but a permanent one,” he said.

IIT-Kharagpur Engineer Builds Device That Fits On Car Exhaust And Reduces Air Pollution

Many cities across the globe are currently combating air pollution, and automotive vehicles are one of the main reasons for this.

However, now an IIT Kharagpur graduate has created a device to help curb pollution caused by vehicles on the road.

The device is called PM 2.5. Developed by Debayan Saha, who has also been a Global Biodesign Fellow at Stanford University. This device is attached with the exhaust of the vehicle. He claims that one car fitted with PM 2.5 can eliminate pollution released from 10 cars in its vicinity.

He said in a statement, "The technology developed by us uses a combination of electric energy and wave energy to influence the pollutants like PM 2.5 such that they act like a magnet attracting other particulate pollutants from the ambient atmosphere to get attached to it. As they grow bigger in size they become heavy and fall off safely on the ground like soil," 

He further added, "One car on the street can now alleviate the pollution in its immediate environment, and potentially neutralize the pollution emitted from 10 cars in its vicinity. Diving really deep into the problem they found main culprit is not PM 2.5 but its tiny size because of which it can easily enter into our lungs and bloodstream." 

Recent research also revealed that air pollution is fastening the process of memory loss in paople and ageing the brain by 10 years. One of the lead researchers stated, "When it comes to remembering a string of words, a 50-year-old in polluted Chelsea performs like a 60-year-old in Plymouth." 

Recently, Delhi's air quality went down considerably.  Even the Center-run System of Air Quality and Weather Forecasting And Research (SAFAR) advised people of the sensitive category to avoid morning walks and any other outdoor activities. Spike in pollution levels has also considerably risen the respiratory and eye-irritation problems in people.

Saha plans to commercialise this product and is currently in talks with various organisations.
