Moffitt Cancer Center researchers develop and test new anti-cancer vaccine

Researchers at Moffitt Cancer Center have developed and tested in mice a synthetic vaccine and found it effective in killing human papillomavirus-derived cancer, a virus linked to cervical cancers among others. The research was published in a recent issue of Cancer Immunology, Immunotherapy.

CU-Boulder-led team finds microbes in extreme environment on South American volcanoes

A team led by the University of Colorado Boulder looking for organisms that eke out a living in some of the most inhospitable soils on Earth has found a hardy few.

A new DNA analysis of rocky soils in the Martian-like landscape on some volcanoes in South America has revealed a handful of bacteria, fungi and other rudimentary organisms called archaea, which seem to have a different way of converting energy than their cousins elsewhere in the world.

Overexpression of proteins 14-3-3 related to chemotherapy resistance

Certain proteins, such as 14-3-3, conserve their basic functions of cell cycle control in diverse organisms, from worms to humans. In a study led by Julián Cerón and Simó Schwartz Jr, researchers from the Bellvitge Biomedical Research Institute (IDIBELL) and the Research Institute of Vall d'Hebron (VHIR) respectively, have described germ line functions of par-5, which is one of the two 14-3-3 proteins existing in Caenorhabditis elegans, worms used as experimental model in genetic studies.

Herbivores select on floral architecture in a South African bird-pollinated plant

Floral displays, such as the color, shape, size, and arrangement of flowers, are typically thought to have evolved primarily in response to selection by pollinators—for animal-pollinated species, being able to attract animal vectors is vital to an individual plant's reproductive success. But can herbivores also exert similarly strong selective forces on floral characters? New research on two sister species in South Africa suggests that this may indeed be the case for inflorescence architecture in the rat's tail plant, Babiana ringens.

Smoking negatively affects response to anti-TNF treatment in patients with rheumatoid arthritis

Berlin, Germany, June 8 2012: A new study presented today at EULAR 2012, the Annual Congress of the European League Against Rheumatism, reinforces current thinking that smoking negatively affects treatment response in rheumatoid arthritis (RA) patients treated with anti-tumour necrosis factor (anti-TNF) drugs.

Lung changes are present in nearly half of ACPA positive RA patients at disease onset

Berlin, Germany, June 8 2012: A new study presented today at EULAR 2012, the Annual Congress of the European League Against Rheumatism, shows that lung changes in association with anti-citrullinated protein autoantibody (ACPA) status are a primary manifestation of rheumatoid arthritis (RA).

Rabbit risk score can help rheumatologists identify patients at high risk of infection

Berlin, Germany, June 8 2012: Results of a study presented today at EULAR 2012, the Annual Congress of the European League Against Rheumatism, suggest that the newly developed RABBIT Risk Score, which calculates the risk of serious infections in patients with rheumatoid arthritis (RA) who are treated with anti-tumour necrosis factor drugs (anti-TNFs) or conventional disease modifying anti-rheumatic drugs (DMARDs) is a valid and effective tool for rheumatologists to predict risk of serious infection.

Parasitic plants 'steal' genes from their hosts

New research published today in BioMed Central's open access journal BMC Genomics reveals that the Malaysian parasitic plant Rafflesia cantleyi, with its 50cm diameter flowers, has 'stolen' genes from its host Tetrastigma rafflesiae. Analysis of these genes shows that their functions range from respiration to metabolism, and that some of them have even replaced the parasites own gene activity.

Study sheds new light on role of genetic mutations in colon cancer development

SEATTLE – In exploring the genetics of mitochondria – the powerhouse of the cell – researchers at Fred Hutchinson Cancer Research Center have stumbled upon a finding that challenges previously held beliefs about the role of mutations in cancer development.

For the first time, researchers have found that the number of new mutations are significantly lower in cancers than in normal cells.

U Alberta finds weakness in armor of killer hospital bacteria

There's new hope for development of an antibiotic that can put down a lethal bacteria or superbug linked to the deaths of hundreds of hospital patients around the world.

Researchers from the University of Alberta-based Alberta Glycomics Centre found a chink in the molecular armour of the pathogen Acinetobacter baumannii. The bacteria first appeared in the 1970's and in the last decade it developed a resistance to most antibiotics.

Immune system 'circuitry' that kills malaria in mosquitoes identified

Researchers at the Johns Hopkins Malaria Research Institute have, for the first time, determined the function of a series proteins within the mosquito that transduce a signal that enables the mosquito to fight off infection from the parasite that causes malaria in humans. Together, these proteins are known as immune deficiency (Imd) pathway signal transducing factors, are analogous to an electrical circuit. As each factor is switched on or off it triggers or inhibits the next, finally leading to the launch of an immune response against the malaria parasite.

Scientists discover huge phytoplankton bloom in ice-covered waters

A team of researchers, including scientists from Woods Hole Oceanographic Institution (WHOI), discovered a massive bloom of phytoplankton beneath ice-covered Arctic waters. Until now, sea ice was thought to block sunlight and limit the growth of microscopic marine plants living under the ice.

Floating dock from Japan carries potential invasive species

NEWPORT, Ore. – When debris from the 2011 earthquake and tsunami in Japan began making its way toward the West Coast of the United States, there were fears of possible radiation and chemical contamination as well as costly cleanup.

But a floating dock that unexpectedly washed ashore in Newport this week and has been traced back to the Japanese disaster has brought with it a completely different threat – invasive species.

What does it mean to be cool? It may not be what you think

Do rebelliousness, emotional control, toughness and thrill-seeking still make up the essence of coolness?

Can performers James Dean and Miles Davis still be considered the models of cool?

Research led by a University of Rochester Medical Center psychologist and published by the Journal of Individual Differences has found the characteristics associated with coolness today are markedly different than those that generated the concept of cool.

Notre Dame research shows food-trade network vulnerable to fast spread of contaminants

University of Notre Dame network physicists Mária Ercsey-Ravasz and Zoltán Toroczkai of the Interdisciplinary Center for Network Science and Applications, in collaboration with food science experts, have recently published a rigorous analysis of the international food-trade network that shows the network's vulnerability to the fast spread of contaminants as well as the correlation between known food poisoning outbreaks and the centrality of countries on the network.
