Crash in sea-turtle births stumps ecologists 

The mystery behind a dramatic fall in the number of leatherback sea-turtle (Dermochelys coriacea) hatchlings in the US Virgin Islands remains unsolved, despite the latest efforts of researchers. Rising temperatures and changes in rainfall patterns — the top two suspects — don’t seem to be connected to the decline, according to a study published on 4 October1. The finding contradicts previous work, leaving researchers scratching their heads over what could be happening.

The latest study focused on a nesting beach in the Sandy Point National Wildlife Refuge on St Croix island in the Caribbean Sea. The researchers found that about 74% of the leatherback sea-turtle eggs laid there in 1990 hatched, but that rate had plummeted to 55% by 2010.

The study analysed detailed temperature and precipitation data at these nests over the 20 years, and found no corresponding trend in either climate-change factor that could fully account for the decline. The researchers reported their results in Royal Society Open Science.

Alzheimer's disease is a sort of dementia that causes problems with memory, thinking, and behaviour. Symptoms usually grow at a slow rate and get worse with time, becoming severe enough to interfere with daily tasks. This illness is an irreversible, dynamic cerebrum issue that gradually destroys memory and thinking aptitudes and, in the end, the capacity to complete the simple tasks. 

 And how would you know if you are suffering from Alzheimer's disease??

 You need to have a blood test for Beta-Amyloid that will help you to Predict Alzheimer Disease Risk. Beta-Amyloid is a protein prevalent in Alzheimer's disease. The test could be utilized in avoidance preliminaries to screen subjectively ordinary patients and figure out which ones are in danger of building up the illness.

 Biocompatibility testing is undertaken to find out if the device is suitable before it is used on someone.

 But the question here is what actually is biocompatibility testing??

 Biocompatibility is, by definition, an estimation of how perfect a gadget is with an organic framework. Biocompatibility can be defined as the capacity of a clinical gadget or material to perform with a suitable host reaction in a particular application. The actual purpose behind performing biocompatibility testing is to decide the wellness of a gadget for human use and to see whether utilization of the gadget can have any possibly hurtful physiological impacts. Before performing biocompatibility testing, it is significant for the maker to have a better understanding of the device materials and manufacturing, sterilization and other processes. The general process of biocompatibility testing can be divided into three steps: planning, testing and evaluating the data.  In the planning stage information on the materials used to produce the gadget ought to be gathered. A biological evaluation plan should also be developed which will determine the type of testing that is required. 

 After the testing is successfully done  then any other tests can be undertaken in it. And it can be used for any medical test undergone in it. 

World Population Day – 11 July 2019

United Nation has declared 11th July as world population day in 1989 and since then it is observed as World Population Day every year. Since the announcement of World population Day 25 years have been passed away yet the target of achieving reproductive health and gender equality have not been achieved.

United Nation has recognized that World Population day is an important event for spreading information related to reproductive health issues globally. The internationally celebrated event focuses on spreading awareness on issues like overpopulation, under population along with birth control. The world population is about 7 billion and as per the UNESCO report each year 83 million people are adding to it. As per the UN there are nine standards for uphold the human rights for planning a family

Non-Discrimination: Age, sex, religion, political affiliation cannot restrict family planning service or information.

Available- The countries should ensure that the family planning commodities are available to everyone.

Accessible- It should be accessible to everyone

Good quality –Clear data about family planning should be communicated

Informed decision making- Countries ensure that there are active participation of individuals that includes health issues

Confidentiality and Privacy: Tthe individuals should have the right to privacy of seeking information related to health issues

Participation: The countries must hold an obligation for ensuring informed participation of individuals in decision making regarding family planning.

Each year World population day comes up with a specific theme, like last year the theme was “Family planning is Human right. In 2019, the theme is focusing on healthcare and reproductive awareness.
