Royal Free Hospital in London will treat a Scottish nurse who has overcome Ebola twice, prior to another ‘late complication’ she suffered from her last infection from the deadly virus.

On Tuesday, the hospital said in a statement that its infectious diseases team is going to conduct the treatment of Pauline Cafferkey. The nurse has undergone treatment for meningitis in last October that she developed from lingering Ebola virus in her system. She contracted the infection for the first time in 2014 when she was in Sierra Leone.

According to the World Health Organization (WHO), in some rare cases, Ebola can endure in the body parts that are not covered by the immune system, like within the eye, in semen, in the brain, or in the spinal cord.

On Tuesday, the US Centers for Disease Control and Prevention (CDC) added two destinations to its list of places facing Zika-related travel warnings.

The CDC has been working with public health officials to monitor for ongoing Zika virus transmission. CDC has placed Trinidad and Tobago and the Marshall Islands into the list of areas with high risk of Zika transmission. The advice given by the CDC is a Level 2 warning that says travelers must ‘Practice Enhanced Precautions’.

The particular regions where Zika virus transmission is ongoing are generally tough to find out and will probably keep on changing with time.

Marine scientists used underwater microphones, known as hydrophones, to capture the sounds of the deep ocean. Some years ago, scientists found some strange noises captured by hydrophones in the Pacific Ocean. The sound was weak and constant during some times of the day, with intensity a few decibels more than the background level and the normal sound level of the ocean. The strange sound had an intensity of 300 hertz and above, which is beyond the sound intensity of whales other marine mammals.

Raccoons are creating a menace offshore British Columbia in Canada due to the elimination of carnivorous predators like local bears, wolves and cougars, which were killed by humans. These predators actually kept a check over the island raccoons, which are capable of causing extreme damages. Domestic dogs are the only natural predators existing on the majority of the islands.

Island raccoons started coming out in broad daylight for strolling and hunting. The population of coastal animals like crabs, worms and fish is decreasing at a shocking rate. Raccoons partially eat crabs and leave the remaining parts. Ecosystem of the island is facing disturbance due to missing large carnivorous predators.

A team of astronomers at the California Institute of Technology claimed to have discovered traces of ninth planet in our solar system. Our solar system comprises many tiny planets, one such example is Pluto, formerly known as ninth planet. However, a celestial body is called a real planet if it is giant and round in shape like other planets in our solar system.

A gene editing tool termed as Clustered regularly interspaced short palindromic repeats (CRISPRs), has the potential to introduce genetic engineering for humans. Scientist Jacob Corn is researching to find a way to put an end to genetic diseases through the help of gene technology. But such a research could lead to many other significant findings that would have broader applications.
