Man may have caused pre-historic extinctions

...th dating fossils from the Pleistocene period. The aim is to provide a far more accurate timetable for the extinction of caballoid horses and mammoths and, ultimately, the cause. "This research is exciting because it throws open the debate as to whether climate change or over-hunting may have led to the...

Large-scale genomics project will hunt genes behind common childhood diseases

...the process of detecting gene variations, with the aim of linking them to particular illnesses. The program will focus on some of the most prevalent diseases of childhood ?asthma, obesity and diabetes, among others ?as well as cancer, all of which are thought to involve the contributions of multiple, in...

Taking the wrinkles out of motoneuronal disease

...ssect synaptic mechanisms," Dr Meunier said. "The aim of our lab is to understand the molecular mechanism underlying neuronal communication. The legacy of millions of years of evolution and competition between venomous species has resulted in deadly neurotoxins capable of blocking neuronal communication...

Loosen up, DNA: Leukemia gene changes genetic packaging

... single gene or protein, many companies are taking aim at the way whole sets of genes are packaged in an attempt to turn on or off several genes at a time. It's part of a field known as "epigenetics": Now that the sequence of chemical bases that make up our genes is largely known, scientists are turning ...

Acidity in the brain could hold the key to stroke treatment

...ow the pH of the brain changes over time, with the aim of providing more targeted and effective treatments. Professor Morris said: "Within two to three years we hope to have developed an NMR technique which can be translated into a machine that can image acidity in the brain. "If we can map stroke dama...

Butterfly farming to help save rain forest

...rounding North Rupununi District with the ultimate aim of enhancing the livelihoods of the 5000 individuals in the 16 rainforest communities in the Iwokrama forest through the sustainable development of a low-tech butterfly farming industry. The butterfly farming will be set up as a co-operative within t...

A protein complex that untangles DNA

...ed for repair and the other for untangling. We now aim to study how this works on a molecular level. This will bring us one step closer to the general goal ?a summary of the many mechanisms that collaborate to maintain our genetic stability", says Camilla Sjögren. ...

Blood test predicts success of quitting smoking using the nicotine patch

...ively using saliva or urine samples. "The ultimate aim here is to distinguish smokers who are likely to benefit from a standard dose of nicotine patch from those who may need a higher dose patch or an alternative therapy in order to succeed in quitting," said lead researcher for the study, Caryn Lerman, ...

UCLA scientists strengthen case for life more than 3.8 billion years ago

...en analyzed in a mass spectrometer. Scientists can aim the beam of ions at specific microscopic areas of a sample and analyze them. While critics noted there are ways to make light carbon in the absence of life, Harrison considers those possibilities to be "extremely unlikely," especially in light of a...

MIT 'seeing machine' offers hope to blind

...f the blind read Braille.) Further, bystanders who aim to help - "there are five steps there; it's the third door on the left" - are often wrong, especially people with good vision, Goldring said. "If you are visually challenged, if you see something once using the machine, you remember." Participants e...

Parkinson's disease mechanism discovered

... Current treatments for Parkinson's disease do not aim at protecting the dopamine-producing neurons themselves. Rather, the treatments seek to restore dopamine levels in the brain or to treat symptoms of the disease. Lindquist cautioned that the findings "have not by any means proven that this mechanism...

Radiation-armed robot rapidly destroys human lung tumors

...stem that uses an accurate, precise robotic arm to aim highly focused x-ray beams at the site of a tumor. Currently there are 76 active CyberKnife sites worldwide (with 45 in the US), and an additional 62 scheduled to be installed globally. Recently, the Pittsburgh researchers upgraded their CyberKnif...

First human study confirms that immune cells can be a primary cause of bone loss in gum disease

...ole it plays in inflammatory bone resorption. The aim of this study, which will be published in the September issue of the American Journal of Pathology, was to identify the cellular source of RANKL in the bone resorptive lesions of periodontal disease. An active periodontal lesion is characterized by ...

Creating a window on 'oceans in motion'

...s, scientists and technical experts at the meeting aim to throw open a large, vivid new global window on marine life by expanding worldwide the work of two pioneering North America-based programs that follow the movements of important species using electronic tags.

Pigeons provide clue to solving common problem in heart patients

... a gene is expressed and at what rate. The group's aim was to see if certain transcription factors might be found in altered amounts in the smooth muscle cells of pigeons that are prone to atherosclerosis. They screened 54 different transcription factors and found that one, known as STAT4, was 10 time...

p53, tumor suppression and aging

...n cancer formation, and many anticancer strategies aim to activate p53 in order to curb tumor formation. Mdm2 is a key inhibitor of p53 and therefore an attractive target to modulate p53 activity in cells. However, conflicting evidence exists regarding whether or not p53-mediated tumor suppression comes ...
