Brain Aneurysms are caused when there is a bulge in a blood vessel caused by a weakness in its wall. When blood flows through the weakened vessel, the pressure causes the area to bulge outwards and cause problems in the surrounding regions. They commonly occur in the abdominal aorta and the brain. Aneurysms can affect any number of people, ranging from 1 in 100 to 1 in 20. Since its treatment is difficult, surgery is usually avoided, but in select cases, it becomes a necessity. In a notable research study, a class of cancer-treatment drugs can be used to treat patients with brain aneurysms.

As per statistics, more than 370,000 people die of coronary heart disease annually. The disease refers to a narrowing of the coronary arteries that supply oxygen and blood to the heart. As per latest research reports, a kind of rare gene mutation may prevent major heart diseases. Previously, scientists have abstained from targeting apolipoprotein B (APOB) gene because it carries a risk of fatty liver disease. However, naturally occurring mutation suggests otherwise.
The study was co-led by a researche from the Boston University of Public Health (BUSPH). The study unearths that protein truncating variants in the aforementioned apolipoprotein B (APOB) gene are directly linked [...]
Just 4 years after the mass production of Penicillin began, the world’s first antibiotic-resistant bacteria were discovered. Even today, Antibiotic-resistant bacteria can cause infections that are virtually untreatable, and therefore consequently fatal. A majority of bacterial strands are slowly growing resistant to the use of antibiotics. This may lead to an increase in infections worldwide in the coming years. However, researchers have investigated a category of viruses, known as Bacteriophages which may able to counter the aforementioned bacterial strands.What Are Bacteriophages?

In a world where Neurogenerative diseases affect millions of people worldwide, there is no significant cure that that can effectively help battle such diseases. In India alone, Multiple Sclerosis affects almost 1 million people yearly. As per latest news, Researchers at the University of Maryland School of Medicine (UMSOM) have discovered a skin-related stem cell that can be used in the regeneration of myelin sheaths, which is an integral part of the human nervous system.
Research performed on mice yielded positive results. Restoration of myelin sheaths in mice led them to believe that stem cells could be a much simpler alternative to using embryonic stem cells. Since the [...]
One of the major hurdles for scientists regarding the creation of human organs via 3D printing was the inability to print the complex vascular structure that can transfer nutrients to nearby tissues. Previously, a breakthrough was achieved in the form of a 3D printed heart, and as per recent reports, Bioengineers from the United States have overcome the aforementioned hurdle and have created a hydrogel model of a lung-mimicking air-pocket/sac, which has airways that can deliver oxygen to surrounding blood vessels.
The team was led by bioengineers from Rice University and University of Washington. The 3D printed lung was designed in such a way that it could include independent [...]
Parkinson’s disease was first mentioned in an essay in the year 1817 by Doctor James Parkinson. An estimated seven to 10 million people worldwide have Parkinson’s disease. Also, an estimated 4 percent of people with Parkinson’s are diagnosed before the age of 50, indicating that the disease can be cured at an early stage if a tangible cure exists. When dopamine levels decrease in the central nervous system, it causes abnormal brain activity, leading to the basic symptoms of the disease.
Although the disease is not fatal, it’s symptoms may lead to incidents that may be fatal in the long run. As per recent reports, researchers from Oxford’s Department of [...]
Visits to the dentist are usually cumbersome and expensive, but the latest development from a team of engineers, dentists and biologists from the University of Pennsylvania have designed a crew of microrobots that can be deployed and controlled to remove the buildup of plaque between the teeth and gums. That is right, scraping and scratching with mechanical tools is not the only methods via which dental clean-ups can be performed.
The scientists have developed two different types of robotic systems for entirely varied purposes. One of them works on open surfaces, whereas the other system is designed specifically to operate inside closed spaces. The researchers showcased the [...]
Cellular Biology is one of the hottest fields in medical science right now. Scientists and Researchers are working on techniques to make cellular biology more accessible, and in such an effort, Researchers from the University of Connecticut have used 3D printing technique to manufacture a portable and affordable microscope that can provide high-resolution 3D images of cells, which can be further used to detect diabetes, malaria and other diseases.
Bahram Javidi, the lead of the research team states that the microscope does not require any staining and labels, which will make the microscope easy to use. He further adds that the microscope will would be of extreme convenience [...]
Medical advancements are occurring side-by-side with the progress in science and technology. Recently, using 3D printers, scientists developed a self-healing rubber material, which can be used in objects to make them last a lifetime. In other news, a fully-functioning heart was also printed using a 3D printer. All these achievements make one wonder about the limits of medical science, and for the right reasons, since MIT engineers have engineered tiny micro robots that can help nanoparticles reach unaccessible targets in the human body and administer the necessary drugs.Challenges Faced
One of the biggest challenges while delivering drugs via nanoparticles is the exit [...]
Dementia is one of the most common chronic disorders found in older-aged people, and what’s more, more than 60 percent of people with dementia suffer from Alzheimer’s disease. First discovered in the year 1906, the disease is incredibly complex to diagnose and takes its toll slowly. One of the most common symptoms of Alzheimer’s is short term memory loss. The long-term symptoms of the same are quite serious. For instance, people lose the ability to sustain independent living and have difficulties in assessing the environment. Regulating Alzheimer’s disease may be much easier from now on, as a long term study has suggested that some forms of blood testing can [...]
With one of the highest death rates worldwide, Cancer leads the pack as one of the most dreadful groups of diseases known to mankind. Cancer is referred to as an unwanted growth of cells in a certain organ or a part of the body. The tumours involved are generally of three types. Benign tumours are not cancerous and cannot spread to different parts of the body. Premalignant tumours are not yet cancerous but may develop cancerous traits later on. On the other hand, Malignant tumours can spread to other organs and parts of the body, making them very fatal to the human body. In recent news from the University of Lincoln, scientists have reproduced a synthetic copy of the Anti-tumour [...]
Along with gadget technology that’s making every bit of our surrounding smarter, innovation in the field of medicine has also moved ahead by leaps and bounds. In March, Google disclosed its alliance with Johnson & Johnson to develop advanced robots to assist surgeons with the operation. Today, bringing the fictional medical science to reality, scientists have created tiny nanobots that will swim through your body to deliver drugs.
The nano swimmers are an invention of researchers at Israel Institute of Technology (Technion). This fine, thread-like structure is introduced into a human body to detect diseases and [...]
