Orgasmic disorders in women are often combined with low self confidence

Written by Dr. H. P. Bustami
Wednesday, 14 May 2008
Womens sexuality is more complex than in men (Courtesy: photocase.com) More than 20% of women report an inability to get frequently vaginal orgasms when having sex with their partner. Also men often believe that women are less able to have a sexually fullfilled lifes. Often it is indeed the case that in partnerships women suffer from female coital orgasmic infrequencies. The reasons can be quite diverse. Be first to comment this article \| Add as favourites (1) \| Quote this article on your site \| Views: 17 \| E-mail

Why do we sleep?

Written by Thomas Hesselberg
Wednesday, 07 May 2008
Although several hypotheses attempt to explain why we sleep, it remains a scientific mystery. Photo courtesy of Photocase.com. Most of us spend about 7-9 hours of the day in a passive state of unconsciousness. Why do we humans have to ‘waste’ around a third of our lives doing absolutely nothing? This time could surely be better used for something else. However, like everything else in the world that surrounds us, sleep has been subjected to evolutionary forces, so since it is observed universally among animals, its advantages must outweigh the costs of less time available for food and mate searching. We know from ourselves that we definitely need sleep, without it, we become drowsy and our mental and motor faculties lose efficiency. With prolonged sleep deprivation we start to hallucinate and lose grasp of reality. The same effects are seen in animals. However, science cannot yet completely solved the mystery of we have to sleep. In a recent review paper, Emmanuel Mignot from the Howard Hughes Medical Institute looks closer at the hypotheses for why we sleep.

Congress of sensory systems in medical school of Tuebingen, Germany

Written by Dr. H. P. Bustami
Sunday, 04 May 2008
Eyes are our most important sense organs. (Courtesy: Photocase) Smelling, hearing, vision, degustation are sensory systems of the body which usually are considered differently. With the coming congress "Molecular Medicine of Sensory Systems" at the university of Tuebingen, Germany, this will change. Scientists from all over the world will join this meeting from 18 - 20th may 2008 to bring together their findings.

Parasite makes ant resemble a fruit

Thursday, 24 April 2008
The parasite changes the appearance of the ant so it resembles a fruit. On the left is the normal ant and on the right is the infected ant. Photo by Stephen Yanoviak from Current Biology (2008) 18: R294. The evolutionary arms race between parasites and their hosts have been ongoing, almost since the first organisms appeared on Earth. The development of hosts defences including immune, chemical and behavioural defences have forced parasites to develop more and more advanced counter-measures. Some of the most impressive outcomes include parasites, which can affect and control the behaviour and physiology of their hosts. A new addition including a parasitic nematode and an ant has recently been described by scientists from the University of Copenhagen, Denmark.

Largest flower flourishing in botanical garden of Bonn Germany

Written by Dr. H. P. Bustami

Titan arum in the botanical garden of Bonn, Courtesy: University of Bonn, Germany It is the largest flower known on earth and it is rarely to see in botanical gardens world wide: Amorphophallus titanum (Titan arum) - growing naturally in Indonesia in rainforests - now gave the honour to some 10.000 visitors at the botanical garden in Bonn, Germany. Only some 2-3 days the impressive spectacular is lasting. Only 10-15 times since 1937 this giant plant showed its 3 metre flowers.

The crispness of crisps

Written by Thomas Hesselberg
Monday, 14 April 2008
Scientists have found a way to use mechanical tests and fracture properties to measure the crispness of crisps such that these quantitative tests agree with qualitative evaluations from taste panels. Photo courtesy of Photocase.com. Few of us realise how much science is involved in the everyday things that surrounds us. Food has not traditionally been much associated with science in the minds of the consumers or producers. However, this is slowly changing, especially with the recent popularity of molecular gastronomy, which attempts to enhance the taste experience by understanding the physical and chemical transformation of the ingredients that occur during cooking. The taste experience of food, however, is not only due to the chemical flavour and the cooking of the food, but often also depends on the texture. This is especially true of potato crisps, where the crispness often determines the success of the product. Traditionally crispness has been evaluated qualitatively by asking people to taste the crisps and state their opinion. However, there is a significant interest among crisp producers in finding a more objective quantitative evaluation. Scientists have now found a way of associating crispness with the fracture properties of the crisps.

Rainforests clean up our athmosphere from pollution

Written by Dr. H. P. Bustami
Sunday, 13 April 2008
Intact amazonas rainforest in Surinam (Courtesy: MPI of chemistry, Mainz, Germany) Rainforests are the most important factor for the world climate. This has been known all along since several decades. And they are extremely endangered by human activities as well. But now a new and surprising finding has been done by scientists from the Max-Planck-Institute of chemistry, Mainz, Germany. The results which recently have been published in "nature" clearly show that intact tropical rainforests can very effectively cleans up the surrounding athmoshere from pollution. The scientists measured in a widely unpopulated area of Surinam (South America) - with no anthropogenic pollution - the air and calculated with complex computer programs the chemical reactions occuring in the athmosphere above the rainforests.

6th European breast cancer congress in Berlin

breast cancer often affects young women (Courtesy: photocase.com) Breast cancer is still one of the most dangerous and deadly cancer types for women. It is a malignant tumor of the mammary glands of women. Around half a million women died in 2007 from breast cancer world wide according to the World Health Organisation (WHO). In Germany with 25% it is among women the most frequent cancer type. But also men can sicken from breast cancer in rare cases.
