New vaccine prevents CMV infection and disease in mice

...ich are also found in other herpes viruses such as chicken pox or herpes simplex – have the same or very similar sequence, structure and function whether in human or mouse viruses, and present a novel target for the host’s T-cells to muster forces and attack the virus. Secondly, the vaccine also contains a “...

'Insulator' helps silence genes in dormant herpes virus

...east and chicken, namely the yeast mating loci and chicken globin locus. To see if insulators play a role in silencing viral genes during the latent phase, Zhou and his group studied cells infected with HSV-1. The studies showed that during a latent period, the virus binds to a host protein called CTCF, a...

Eating with our eyes: Why people eat less at unbused tables

...ents at a sports bar where an open buffet featured chicken wings during the Super Bowl; some tables were bused and some were left unbused. To use environmental cues to curb overeating and overdrinking, Wansink suggested that college parties could encourage (or require) fresh plastic glasses for each drink ...

Bypassing eggs, flu vaccine grown in insect cells shows promise

...the production of millions of eggs. Not relying on chicken eggs might also be advisable in case a bird flu pandemic hits chicken flocks hard. The insect-cell technology also simplifies the manufacturing process in another way: A ...

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

...ifferentiate after transplantation in the ears of chicken embryos. The two different approaches - new drugs and stem cell transplants - are important because drug treatments are unlikely to help everyone. For some people with genetically caused hearing disorders, he explained, no drug is likely to hel...

Bird sex is something else

... and mice. In several types of finch and embryonic chicken brain tissue, Z chromosome genes were expressed up to 40% higher in ZZ males than ZW females. This contrasts with findings from the mammal samples, where dosage compensation meant that the male: female ratio of X-linked genes is similar to that of au...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...n their drinking water. One dose should protect a chicken for weeks. Flu is a major problem in the horse racing industry and in domestic horses. It also has very recently become a problem in domestic dogs in the USA and domestic cats are susceptible to H5N1 virus. The Warwick research team has now filed...

The researchers built up layers of their SWNTs to produce a film that is electrically conducting even at a thickness of just a few n...

Scientists find a key to immune system's ability to remember

Making a face: A new and earlier marker of neural crest development

... of biology and development reach far beyond these chicken and eggs." Based on work from the 1940's before molecular tools were available, the neural crest was thought to form by interactions between neural and non-neural cell layers. "We show in this work that neural crest stem cell precursors are design...

Researchers identify human DNA on the fast track

... years separating the evolutionary lineages of the chicken and the chimp. Incredibly, since the human lineage separated from that of the chimp, 18 of the 118 nucleotides have changed. This region "stood out," said Pollard. But what does it do? To find out, Pollard began working with the wet lab, led by Sof...
