Pauline Cafferkey, a nurse from Scotland who was hospitalized for a third time due to late complication after successfully fighting Ebola, has been discharged, announced Royal Free Hospital in London. Earlier, the nurse has twice recovered from the lethal virus causing serious health issues.

The hospital also announced that the Scottish nurse, who was taken to the hospital last week, is not infectious. It was not the first time when Cafferkey had a meeting with the hospital's infectious diseases team. She had been treated for meningitis in October last year. According to doctors, the nurse developed late complication from Ebola virus in her system.

A new budding study has revealed that the problem of obesity might have an adverse impact on memory. Obese people are likely to have a weaker memory than the thinner counterparts.

Earlier, an experiment was performed by the researchers at University of Cambridge, debating that a loss of memory relating to the recent meals might possibly result in overeating. However, the researchers very specifically pointed out that obesity does not harm other parts of the memory that pertain to things are general knowledge.

Lincoln Seay, who is seven months old, received a heart donation just before the doctors and his parents started losing hope. The Alaskan infant suffered from a rare heart condition since birth and finally had the transplant he needed the most, only a few days prior to what everyone thought were left with Lincoln. The heart transplant took place at Seattle Children’s. Though the baby had a web of tubes and a big enough scar, he was in senses and kicking last week.

To be better prepared for water scarcity in future, researchers are getting help from natural sources, including Namib Desert beetle. They believe a beetle, a cactus and a pitcher plant can tell how to harvest water from atmosphere.

A new study by researchers at Harvard University stated that a new material has been developed on the basis of the Namib Desert beetle’s bumps on its shell which may tell how water can be harvested. The study has been praised by many scientists who believe such methods can help save the world’s areas affected by droughts.

The new method developed by the researchers may tell how to use natural resources to generate water from condensation. The Harvard researchers believe the method could have real world impact.

Small size of wisdom teeth has baffled researchers since long. But now, they have an explanation to prove why there is difference in modern human and hominins’ teeth sizes.

A new study by Monash University researchers suggests that evolution of human was simpler than previously believed. It also showed that it is now easy to predict sizes of teeth missing from prehistoric human remains.

For the study, the researchers analyzed human teeth and hominins fossils to ensure that wisdom teeth follow ‘the inhibitory cascade’ rule, which states that size of a particular tooth depends on the size of the tooth next to it.

Astronomers don’t have direct evidence to prove that solar system has nine planets, and not eight. But, they believe ‘Planet Nine’ could be hiding in dark hurtling around the cosmos. Now, Cassini spacecraft is going to help scientists search the distant world in dark abyss of the outer solar system.

NASA’s Cassini probe, which has been studying Saturn and its natural satellite since 2004, is currently hunting for ninth planet in solar system’s dark regions. Major challenge astronomers are facing while looking for the Planet Nine is the enormous length of a year for the planetary body. Usually, they take two photographs of a space object at different period of time, but in the case of the Planet Nine, they don’t have any image of it.
