The plant pathogen that caused the Irish potato famine in the 1840s lives on today with a different genetic blueprint and an even larger arsenal of weaponry to harm and kill plants.

Researchers from the University of York have demonstrated that the change in cannabis declassification in 2009 has coincided with a significant increase in hospital admissions for cannabis psychosis - rather than the decrease it was intended to produce.
The UK Misuse of Drugs Act (1971) divided controlled drugs into three groups – A, B and C – with descending criminal sanctions attached to each class. Cannabis was originally assigned to Group B, but in 2004, it was transferred to the lowest risk group, Group C.
The search for new drugs, including those for cancer, is set to speed up thanks to a new research technique invented by scientists at the Nanyang Technological University (NTU).
Named the "Cellular Thermal Shift Assay" (CETSA), scientists can now know for sure if a drug had reached its target protein in the body, which is a critical step in determining the effectiveness of most medicines.
IFR microbiologists are reinvigorating a way of battling C. difficile infections that they hope will help overcome the growing problem of antibiotic resistant superbugs in hospitals.
A new computational method for working out in advance whether a chemical will be toxic will be reporting in a forthcoming issue of the International Journal of Data Mining and Bioinformatics.
Persons with Alzheimer's disease are able to manage their everyday activities longer and they suffer from less psychological and behavioural symptoms if the diagnosis is made and treatment begun at a very early phase of the disease, indicates a recent study conducted at the University of Eastern Finland.
The study followed persons with Alzheimer's disease over a course of three years. The study participants were diagnosed either at the very mild or mild phase of the disease and treated within the standard healthcare system.
University of Adelaide research has shown new evidence that dinosaurs were warm-blooded like birds and mammals, not cold-blooded like reptiles as commonly believed.
In a paper published in PLoS ONE, Professor Roger Seymour of the University's School of Earth and Environmental Sciences, argues that cold-blooded dinosaurs would not have had the required muscular power to prey on other animals and dominate over mammals as they did throughout the Mesozoic period.
Cancer survivors were twice as likely to experience severe menopausal symptoms compared to women who have not had cancer, a new Australian study has found.
The study was led by the University of Melbourne and the Royal Women's Hospital Melbourne, with the King Edward Memorial Hospital and the University of Western Australia.
The study was published in Menopause, the Journal of the North American Menopause Society.
(Santa Barbara, Calif.) –– Two types of small beach critters –– both cousins of the beloved, backyard roly-poly –– are suffering localized extinctions in Southern California at an alarming rate, says a new study by UC Santa Barbara scientists. As indicator species for beach biodiversity at large, their disappearance suggests a looming threat to similar sand-dwelling animals across the state and around the world.
No, those are not cars darting along a busy highway. The glowing specks you're seeing in this video (http://bit.ly/110LTfm) are millions of nuclei flowing through the tube-like filaments, or hyphae, of a single fungus cell.
The video was produced as part of a study by UCLA mathematician Marcus Roper's research group that was the first to measure and explain this dynamic movement of nuclei in the cells of a fungus.
Asian Indians are one of the fastest growing ethnic groups in the United States, and roughly half a million people of Indian ancestry live in California — more than any other state. Individuals from this group are strongly predisposed to obesity-related conditions such as diabetes and heart disease, due in large part to physical inactivity, diets low in fruit and vegetables, and insulin resistance.
Montreal, Canada, July 18, 2013 – A study conducted by the team of Dr. Jean-Claude Tardif, Director of the Research Centre at the Montreal Heart Institute (MHI), has led to the discovery of a new approach to treat aortic valve stenosis through the administration of a compound that prevents valve deterioration and can even reverse the progression of the disease. A condition that is characterized by a narrowing of the aortic valve and that affects approximately 150,000 Canadians , aortic valve stenosis is the most common type of heart valve disease in Western countries.
Adrenocorticotropic hormone is recommended worldwide as an initial therapy for infantile spasms. However, infantile spasms in about 50% of children cannot be fully controlled by adrenocorticotropic hormone monotherapy, seizures recur in 33% of patients who initially respond to adrenocorticotropic hormone monotherapy, and side effects are relatively common during adrenocorticotropic hormone treatment.
Crop rotation has been used since Roman times to improve plant nutrition and to control the spread of disease. A new study to be published in Nature's 'The ISME Journal' reveals the profound effect it has on enriching soil with bacteria, fungi and protozoa.
"Changing the crop species massively changes the content of microbes in the soil, which in turn helps the plant to acquire nutrients, regulate growth and protect itself against pests and diseases, boosting yield," said Professor Philip Poole from the John Innes Centre.
Washington, DC (July 15, 2013) – The long-distance relationship has plagued college students and people relocated for work for ages. These relationships are seen as destined to fail, but are they actually creating stronger bonds than a geographically closer relationship? A recent paper published in the Journal of Communication found that people in long-distance relationships often have stronger bonds from more constant, and deeper, communication than normal relationships.
