Drink (BBC) Sweetener 'not linked to cancer'  - BBC  The artificial sweetener aspartame is not linked to cancer, according to a report just released by the European Food Safety Authority (EFSA). The European food watchdog undertook an urgent review of the additive following a study, published in 2005, which suggested aspartame was carcinogenic. But a working party said the incidence of tumours could not be linked to the artificial sweetener. The sweetener showed no evidence of genotoxity - the ability to damage DNA. For aspartame, the ADI is set by the European Commission's Scientific Committee on Food (SCF) at 40 milligrams per kilogram of body weight.   
'Cloaking device' idea proposed  - BBC  Nicolae Nicorovici and Graeme Milton propose that placing certain objects close to a material called a superlens could make them appear to vanish. It would rely on an effect known as "anomalous localised resonance". However, the authors have so far only done the maths to verify that the concept could work. Building such a device would undoubtedly pose a significant challenge. The concept is at such a primitive stage that the scientists talk only at the moment of being able to cloak particles of dust - not spaceships. One way to construct a cloaking device is to use a superlens, made of recently discovered materials that force light to behave in unusual ways. Even though light is hitting the speck of dust, scattering of the light is prevented by the cloak which is in close proximity." But they admit the cloaking effect works only at certain frequencies of light, so that some objects placed near the cloak might only partially disappear.

Epstein-Barr Virus Might Kick-start Multiple Sclerosis - Science Daily  Left: Multiple sclerosis is a chronic inflammatory disease of the central nervous system (CNS) thought to be mediated by T cells attacking the insulating myelin sheath of nerve cells. EBNA1-specific T cells (1) or antibodies (2) could falsely recognize and attack CNS auto-antigens, a process called molecular mimicry. Or EBNA1-specific T cells could ramp up the action of auto-aggressive myelin-specific T cells with soluble pro-inflammatory molecules such as interferon-gamma, a mechanism termed bystander activation (3). In addition, latent EBV antigens could sustain the survival of auto-reactive B cells (4), or they could be triggered by auto-antigens that initiate viral replication (5), in turn elevating EBV-specific T cell responses (6). (Illustration: Jan LĂĽnemann)  Researchers have found that patients with multiple sclerosis (MS) carry a population of immune cells that overreact to Epstein-Barr virus. The virus, which causes mononucleosis and may contribute to some cancers, has long been suspected to play a role in MS. However, the mechanism linking the virus to the disease was poorly understood. “The susceptibility to acquire MS is inherited, but environmental insults such as viral infections are thought to trigger the disease.“
