Asexual worm quickly adapts to soil contamination

...dapt to stress less easily than sexual species. At present these asexual species are used as test organisms in ecotoxicological risk evaluations. The question now arises as to whether they are suitable for this purpose. The results of this study are important for the development of protection strategies ...

Thymus transplants gives hope to babies with fatal immune disease

...hile researchers ensure that there are no diseases present in the tissue. Strips of tissue are then implanted in the baby's thigh, where they attract a blood supply and begin to act like a thymus gland. Within three to four months, mature T cells begin to appear in the bloodstream. The latest Duke analysi...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...forming Arts and also the University of Iowa) will present some detailed new results from a National Center f...e, MA ( jdkemp@cambridgesoundmanagement.com ) will present a computerized modeling tool that allows architects and acoustical consultants to maximize speech pr...

Herpes infection may be symbiotic, help beat back some bacteria

...nfection. In latent viral infections, the virus is present for the lifetime of the host in a relatively quiescent form that does not cause overt symptoms. While presenting their results, researchers stressed that they did not want to minimize or in any way disregard the human suffering and health risks ca...

The quest for an effective HIV vaccine presents new possibilities, challenges

...hnston and Fauci assert. Vaccines of this type present several complications, however. T-cell-mediated control of HIV infection may not stave off disease forever. Additional human studies would be needed to determine if the vaccine also reduces the spread of HIV. Finally, an HIV vaccine that delays but d...

Bats get the munchies too!

...e Ben-Gurion University of the Negev (Israel) will present data demonstrating this on Sunday 1st of April at the Society for Experimental Biology’s Annual Meeting in Glasgow. The concentration of ethanol rises in fleshy fruits, such as figs and dates, as they ripen. Egyptian fruit bats prefer these fruits...

Detecting poisons in nectar is an odour-ous task for honeybees

...s? Dr Geraldine Wright (Newcastle University) will present data on how toxins in nectar affect a honeybee’s willingness to eat floral nectar on Sunday 1st April at the Society for Experimental Biology’s Annual Meeting in Glasgow. Honeybees are very clever and can learn to associate almost any colour, shap...

Fat overrides effects of vitamin C

... as diet, certainly play a part. Nitrite, which is present in our saliva and is derived from nitrate in our diet, is thought to be a pre-carcinogen for gastric cancer. When it is swallowed and enters the acidic environment of the stomach, nitrite spontaneously forms nitrosating species able to convert a rang...

Individuals and populations differ in gene activity levels, not just genes

...evelopment of humans from our ancient ancestors to present day. The research may also help us understand why some people are more susceptible than others to complex genetic diseases....

Proteasome activator enhances survival of Huntington's disease neuronal model cells

...oteins. When proteins or peptides mutate, they can present major problems to the clearing up of the intracellular environment. In Huntington's disease (HD) the disease provoking mutation in the huntingtin gene eventually causes the cell to build up intranuclear and cellular inclusions of protein-aggregates, ...

Man's best friend lends insight into human evolution

...e Max Planck Institute in Germany, this ability is present in other species as well. As Hare discusses in the April issue of Current Directions in Psychological Science, chimpanzees utilize social cues like eye gaze and face orientation to monitor others' behavior or infer motives of other subordinate or do...

It's never too late to get it back! Aging interrupted

..., healthy humans? says Professor Spindler who will present his results at the Society for Experimental Biology’s Main Meeting in Glasgow on Monday 2nd April. Previous research has show that mice can live up to 40% longer if they simply consume fewer calories, but a highly nutritious diet. Because people a...

Transfusion expert urges wider use of filtered blood

...cording to University of Rochester researchers who present their analysis in the April journal, Transfusion. The practice of removing the white cells from blood is called leukoreduction. But despite the recommendations of two national advisory committees in 10 years that voted in favor of all patients in th...

Ancient genes used to produce salt-tolerant wheat

...wheat line about 35 years ago and are normally not present in any modern wheat." The project began when the CSIRO team used a highly accurate selection method -- based on their understanding of how plants tolerate salt -- to identify wheat varieties that could cope with higher salinity. They were particul...

Scientists genetically engineer tomatoes with enhanced folate content

...ole problem by ensuring that the folate is already present in the food." Will doctors be recommending a healthy dose of salsa for would-be pregnant women anytime soon? Probably not, the researchers say. "It can take years to get a genetically-engineered food plant approved by the FDA," Hanson said. "Bu...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

... approach is that it utilizes a chemical signature present on histones but not DNA. Existing methods to predict enhancers rely on the DNA sequence alone, but these are inadequate because we have an incomplete understanding of the sequence features that identify enhancers. The elucidation of a common histone ...

Row over study puts Korea's scientific community under scrutiny again

...What is indisputable is that Dr Kim's name was not present in the later version of the paper and that in his place as lead author was Dr Cha, his former employer and the head of CHA Health Systems, a "global healthcare enterprise" whose interests include the CHA Stem Cell Institute and several hospitals and ...

Changes in amino acids in the 1918 influenza virus cut transmission

...t subtypes of hemagglutinin called H1 through H16, present in influenza virus strains circulating in birds. H1 and H3 are found today in human influenza viruses. Hemaglutinin helps open the door to the cell to allow the virus to infect. The first step is in this process is the binding of the hemagglutini...

Researchers identify gene involved in dog size

...rticularly exciting because the underlying gene is present in all dogs and other diverse species, including humans,?said Eric Green, M.D., Ph.D., scientific director of the NHGRI Division of Intramural Research. “Discoveries like this illustrate the exciting promise of genomics research for understanding the...

Need oxygen? Cells know how to spend and save

...ells in normal oxygen conditions (what's generally present in normal room air) compared to cells grown in hypoxia. In low oxygen, liver, uterus, lung and colon cells all made COX4-2. The researchers then exposed mice to hypoxia for a few weeks and found that they too showed increased levels of COX4-2. In...
