Penguin chicks exposed to human visitors experience spike in stress hormone

...e because, unlike a hormone such as adrenaline, it takes several minutes for corticosterone to build up in the bloodstream after a stressful event, such as being captured. Additional blood samples were drawn after 30 and 60 minutes. The same procedures were followed when the chicks were 40 to 50 days old a...

New technique rapidly detects illness-causing bacteria

...ch like with a pregnancy test. The entire process takes only 35 minutes, while traditional gene amplification techniques may take many hours. Promising early results suggest the sensitive method could detect fewer than 100 cells of a pathogen in just half an hour. Nugen's software also compares a target...

MSU researchers receive $4 million grant to uncover gene functions

...s of a chloroplast, the MSU team estimates that it takes only around 4,000 genes to make a functional chloroplast, which is similar to a simple bacterium, rather than the tens of thousands of genes required to make a whole plant. "If we completely understand the chloroplast, it should then be possible to ...

Beauty queens urge girls not to sacrifice their bones

... Osteoporosis Risk Test. Maximum bone development takes place in girls and boys roughly between ages 11-17. By building peak bone mass during this period, young people "invest in their bones" and reduce the risk of fracture later in life, noted Professor Ghassan Maalouf, an IOF Board member from Lebanon w...

AIDS expert says global strategy needed to combat feminization of HIV/AIDS

...mselves and a gender-specific vaccine program that takes into account the different immune responses between women and men. Cultural programs are also needed for reshaping gender roles, such as educating more women about safe-sex practices, use of condoms, lessons on negotiating safe sex, and awareness ca...

Researchers create infectious hepatitis C virus in a test tube

...iruses, HCV cannot replicate by itself; instead it takes over the machinery of a host cell to make copies of itself. Much about the life cycle of HCV remains poorly understood because scientists have been unable to reproduce an infectious form of HCV that they can observe in cell cultures. The method devel...

Device traps, disables harmful bacteria

...trations. "This specific filter has a blower that takes a high volume of air and puts it through a filter that screens bacteria and even smaller particles," said Angenent, a member of Washington University's Environmental Engineering Science Program. " And after the filter there is UV light; if something ...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

... the cell, the invading microbe's genetic material takes over, turning the 'host' cell into a factory to produce more copies of the virus, which then spill out to invade other cells in the body. Scientists had assumed that once a virus begins fusing with a cell's membrane, infection of the host cell was i...

Modification of program enables prediction of gene transcription

...en known to exist before," Brent said. The system takes advantage of the scarcity of the CG sequence, finding so-called CpG "islands" known to be more common near the transcription-start site. It also has a knack for recognizing sequences that indicate splice sites. Over the past two years, TWINSCAN has b...

Genetically engineered animals help in scientific research that may benefit children

"This animal model has the advantage of mimicking in a short time the different stages of chronic kidney disease. The combination of genetic...

Gaining ground in the race against antibiotic resistance

In some cases, there is a tradeoff associated with antibiotic resistance: the bacteria's success in fighting a particular antibiotic can cause it to lose ...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

At a time when setbacks have cast doubt on the future of gene therapy, the results also provide assurance that it can be performed without causing undue harm to patients. The clinical trial, which was conducted at the ...

Tadpole soon to help in the fight against cancer and lymphedema

... Lymphatic vessels can be studied in mice but this takes time and is extremely complex. Moreover, a study of mice only enables the examination of gene per gene, which complicates revealing the combined action between various genetic factors. For efficient research smaller model organisms are used, such as ...

The finding may explain, at least in part, why transmeridian travelers suffer from jet lag, the malaise experienced after crossing several time zones. The new understanding could eventually lead to the development of medi...
