Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Changes in hormonal status have no impact on women's voice parameters

In recent years several studies have suggested that women's voices change at different times over the menstrual cycle, with the tone rising as ovulation approaches. Now a study conducted by researchers at the West Texas A&M University in which women's voices were subjected to computerized acoustical analysis contradicts those findings.

IncP-1 plasmids can transport antibiotic resistance genes between bacterial species

The part of bacterial DNA that often carries antibiotic resistance is a master at moving between different types of bacteria and adapting to widely differing bacterial species, shows a study made by a research team at the University of Gothenburg in cooperation with Chalmers University of Technology. The results are published in an article in the scientific journal Nature Communications.

African-American adults with CVD may benefit from 'sunshine vitamin'

In recent years supplementation with Vitamin D has been shown to reduce the risk of cardiovascular disease in people who are deficient in the vitamin.

Strong bitter taste can cause nausea: Research

Swallow the good, spit out the bad. A new study from the Monell Center highlights the vital role taste plays as the body's gatekeeper. The research shows that strong bitter taste in and of itself can cause people to both report the sensation of nausea and display a pattern of stomach activity characteristic of actual nausea.

Obesity impacts gene clock of cardiovascular system

Obese individuals typically suffer more medical problems than their leaner counterparts. They are more likely to be diagnosed with insulin resistance, diabetes, increased stress hormones, hypothyroidism, and sleep apnea. Researchers at the Georgia Health Sciences University in Augusta have also found the potential for something else, using an animal model.

Study on 'health halo effect'

Jenny Wan-chen Lee, a graduate student in Cornell University's Dyson School of Applied Economics and Management, has been fascinated with a phenomenon known as "the halo effect" for some time.

Tai chi, green tea may help reduce inflammatory diseases in postmenopausal women

C.S. Lewis, the famous author and Oxford academic, once proclaimed "You can't get a cup of tea big enough or a book long enough to suit me." We sip it with toast in the morning, enjoy it with sweets and biscuits in the afternoon, and relax with it at the end of the day.

Takeda, Heptares collaborate to develop new drugs against CNS disorders

Heptares Therapeutics and Takeda Pharmaceutical Company today announced the formation of a two-year drug discovery collaboration focused on a single G-protein coupled receptor that plays an important role in the pathology of central nervous system disorders.

Researchers discover new avenue for hypertension, cardiovascular disease treatment

More than one-third of the world's population suffers from hypertension and cardiovascular disease. The U.S. Agency for Healthcare Quality and Research has reported that Americans spent $29 billion for non-prescription cardiovascular drugs alone in 2008.

Scientists identify novel mechanism to control cancer spread

Saint Louis University researchers have identified a novel mechanism to control the traffic of cells and fluid from tissues to lymphatic vessels. It may be possible to harness this mechanism to fight cancer spread from one organ to another organ and improve the effectiveness of vaccines.

Louisville Chief of Cardiovascular Medicine earns APS' Walter B. Cannon Award

Heart failure affects roughly six million Americans, yet treatment consists of either a heart transplant or the insertion of mechanical devices that assist the heart. This is unacceptable to Roberto Bolli, MD, Chief of the Division of Cardiovascular Medicine at the University of Louisville in Louisville, Ky., which is why he is on a mission to make cardiac stem cell treatment an option for all who must cope with the limitations of a failing heart.

Blueberry polyphenols can reduce obesity

The benefits of blueberry consumption have been demonstrated in several nutrition studies, more specifically the cardio-protective benefits derived from their high polyphenol content.

ASBMB honors Stanford professor with DeLano Award for Computational Biosciences

Stanford University professor Axel T. Brunger has been named the winner of the American Society for Biochemistry and Molecular Biology's inaugural DeLano Award for Computational Biosciences. Brunger will present his award lecture, titled "Towards Structural Biology with Single Molecules" at 9:03 a.m. on Wednesday, April 13, at the Experimental Biology 2011 conference at the Walter E. Washington Convention Center in Washington, D.C.

Symposium to discuss about controversies over politicization of science

Science is playing an increasingly prominent role in many controversial political, religious and socio-economic debates, such as those about embryonic stem cells, genetically modified foods, teaching evolution and climate change.

Scientists discover unknown function of dopamine in brain

A study of the salamander brain has led researchers at Karolinska Institutet to discover a hitherto unknown function of the neurotransmitter dopamine. In an article published in the scientific journal Cell Stem Cell they show how in acting as a kind of switch for stem cells, dopamine controls the formation of new neurons in the adult brain. Their findings may one day contribute to new treatments for neurodegenerative diseases, such as Parkinson's.

New discovery in cancer and gene therapy

DNA's role as the master blueprint of the cell means that even small sequence changes can have catastrophic consequences. For this reason, much of our understanding of cancer development comes from studying how cells copy DNA and repair sequence errors--and how these processes can go wrong.

New insight into acute pancreatitis

Timing is everything. That's especially true when it comes to the activation of enzymes created by the pancreas to break down food. When the timing is right, those enzymes are activated only when they reach the gut, where they get to work releasing and distributing nutrients that we need to survive.
