The consequence of excessive sleepiness among Americans
A recent research shows that 1 in 5 US complain excessive sleepiness. This is almost 20%. This data increase concerns about public safety and the possibility for misfortunes and damages. The study from Stanford University found out that at this percentage also belongs 11% that report severe sleepiness. The excessive sleepiness is widespread and is much common in the United States than in Europe. Stanford sleep expert Maurice Ohayon, declared that according to a study that was published in 2002 in the Journal Neurology shows that the prevalence of excessive daytime sleepiness in five European countries was about 15 per cent.
Scientists have studied statistics from a representative sample of 8,937 people 18 or older living in Texas, California, and New York. The members were asked by telephone about their sleeping habits, health, sleep problems, and mental disorders.
It is made a step forward in forming a synthetic living cell
A group from the University of Nottingham has taken some significant first steps in order to create a synthetic copycat of a living cell.
Using specific substances such as polymers - long-chain molecules - Dr Cameron Alexander and PhD student George Pasparakis in the University’s School of Pharmacy have constructed capsule-like structures that have properties mimicking the surfaces of a real cell. Experts demonstrate how they have been able to persuade the capsules to talk to natural bacteria cells and transfer molecular information.
According to the scientists, the breakthrough could have a number of prospective medical uses.
That technology could be used for the growth of new targeted drug delivery systems, where the capsules would be used to carry drug molecules to attack precise diseased cells in the body, whereas leaving healthy cells intact, in that way reducing the number of side influences that can be connected with treatments for life-threatening diseases such as cancer.
People are going to “replace” God
This scaring event has happened sooner than predictable. Scientists have managed to synthesize 1.08 million base pair chromosome of a modified Mycoplasma mycoides genome in a non-for profit lab in the US.
Researchers at the J. Craig Venter Institute, made available results that describe the successful building of the first self-replicating, synthetic bacterial cell. The group synthesized the 1.08 million base pair chromosome of a modified Mycoplasma mycoides genome. The synthetic cell is the evidence of standard that genomes can be designed in the computer, chemically made in the laboratory and transplanted into a recipient cell to produce a new self-replicating cell restricted only by the synthetic genome.
Teenager with 4 kidneys is willing to donate them
A girl of 18 years old, Laura Moon, from Whinmoor in Leeds, has four kidneys. All of them are functional and growing naturally. She would like to donate the additional kidneys to people who are helpless without a transplant.
The most interesting fact is that Laura became conscious of her ‘unusual anatomy’ only six months ago when she went to have an ultrasound scan at the Seacroft Hospital in her birthplace of Leeds. The ultrasound scan was to examine stomach pains because of a road accident. She told that she realized that the doctor scanning her hadn’t said anything for a long time. She thought he was going to give her some bad news,but then he said that she has got four kidneys.
Two of Ms. Moon’s kidneys measure 14cm and the other two are 9cm. The doctors who treated her, asked for her agreement to take photos and to show them to University students.
Better treatment in order to combat tuberculosis
According to data published by some experts, more than nine out of ten cases of tuberculosis, which kills 1.8 million people each year, could be averted by 2050 with better testing, drugs and vaccines.
Lesotho Health Minister Mphu Ramatlapeng at discussion in Geneva, where the report was unveiled at the World Health Organisation (WHO) mentioned that nowadays tuberculosis is outmoded.
Some 36 million people infected with TB during 1995-2008 were cured and incidence of the lung-wasting disease has begun to move back, but only by about one percent per year.
It’s registered that he majority of cases, more than 80 percent occur in only 22 countries, including nine in Africa, 11 in Asia, and Russia.
Revealing rates have enhanced over the last 15 years, but nearly 40 percent of active infections in those nations still go untreated.
