Scientists created lab-grown lungs and transplanted them successfully into pigs

This work represents a considerable advance in the lung tissue engineering field. Following this experiment success, scientists believe they are close to being able to transplant bioengineered lungs into people with life-threatening conditions and make the transplant waiting list a thing of the past.

Scientists developed a new compound to reverse balding, hair whitening and skin damage

In a series of experiments with mice, investigators have used an experimental compound to successfully reverse hair loss, hair whitening and skin inflammation linked by previous studies to human diets heavy in fat and cholesterol. The findings highlight possible pathways for addressing hair loss and skin wounds in humans with medications.

Scientists identify exoplanets where life could develop as it did on Earth

Researchers have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist. Their study proposes that stars which give off sufficient ultraviolet (UV) light could kick-start life on their planets in the same way it likely developed on Earth, where the UV light powers a series of chemical reactions that produce the building blocks of life.

Discovery of a brand new type of lung cells shows promise for curing cystic fibrosis

Scientists discover a new type of lung cells. Specific mutations in these cells appear to cause cystic fibrosis, a multiorgan disease that affects more than 70,000 people worldwide. These new cells serve as promising targets for future treatments against cystic fibrosis.

No clear link yet between brain cancer and electromagnetic fields of modern world devices

Large-Scale research shows no positive association between exposing head to significant amounts of high-frequency electromagnetic fields and primary brain tumours. However, scientists warrant further investigations to analyse any potential risk.

New anti-cancer drugs put cancer cells into permanent sleep

Researchers discovered a new class of drugs that can completely stop tumour cells growth by blocking key genes involved in cancers like blood and liver cancers. Unlike chemotherapy and radiotherapy, this class of drugs causes no damage to healthy cells.

New diagnostic device to detect traumatic brain injuries

Brain traumatic injuries mainly diagnosed through costly and hospital-based CT scan radiations. Researchers have now developed a small device that analyses the level of certain proteins in the blood and allows, using a single drop of blood, to diagnose the possibility of a mild traumatic brain injury. This discovery, will not only free patients from often long waits in the emergency departments but also save on costly medical examinations.

For the first time, ‘Reprogrammed’ stem cells to be tested in people with Parkinson’s

For the first time in the world, researchers will conduct clinical studies transplanting reprogrammed stem cells in the brains of patients with Parkinson’s disease to supplement damaged nerve cells. The team has already tested the process on monkeys, and they found that the movement of the affected animals improved without causing cancer in the brain.

Weight loss easiness found to be dependent on a person’s gut bacteria

A new small study finds that people’s gut bacteria may play a role in determining how easy, or difficult, it is for them to lose weight. The research suggests that people who have more carbohydrate-using bacteria would respond better to a low-carb diet. So, in the future doctors would be able to modify the weight loss plan based on an individual’s gut bacteria; or change the makeup of the gut bacteria using probiotics before instituting a weight loss program. However, the findings need to further confirmation with larger studies.

NASA’s to launch Parker Solar Probe in a human’s first mission to explore the sun

With the aim to understand the influence of solar activity on Earth and other worlds, NASA will launch the Parker Solar Probe spacecraft. It will travel to within 4 million miles of the sun’s surface, confronting brutal radiations and temperature of 1 million degrees F. As the sun is the only star we can visit, this mission will also gather valuable information about how stars work everywhere.
