Scratch no more: Gene for itch sensation discovered

...isorders like eczema, or it can stem from a deeper problem such as kidney failure or liver disease. It can be a serious side effect of cancer therapies or powerful painkillers like morphine. For some people, chronic itching can be very disruptive, interfering with sleep or giving rise to scratching that lead...

Researchers discover inherited mutation for leukemia

...enetic and epigenetic alterations when identifying problem genes," he says. CLL is the most common form of adult leukemia, with 15,300 new cases and 4,500 deaths from the disease expected this year in the United States. The leukemia is slightly more common in men than women, and typically strikes people ...

The insect vector always bites twice

... vector-borne diseases has been recognized and the problem is prompting research scientists to take a strong interest. Most of these infections, classified as emerging or re-emerging diseases, are linked to ecosystem changes, climatic variations or pressure from human activities. Malaria, sleeping sickness a...

...oprotection because they are toxic,” he says. “The problem is, if you use lower concentrations, you cannot get true vitrification.” The agents are needed to intercept water so it won’t form ice. Interestingly if small ice crystals form during cooling, they can get larger during de-vitrification, which takes ...

Researchers examine carbon capture and storage to combat global warming

Physicist cracks women's random but always lucky choice of X chromosome

...ystem to our olfactory apparatus. Coming at the problem from the perspective of a physicist Dr Nicodemi has found an explanation for the random selection based on thermodynamics. Research has already shown that at the key moment in this process both X chromosomes are brought close together within the cell...

Exploring the dark matter of the genome

...en notes that one intensively studied and puzzling problem in chromosome biology will benefit enormously from the new findings: epigenetics -- the inheritance of traits and genetic information as controlled by proteins associated with the chromosomes, rather than by DNA sequence. Starting in the 1920s, epige...

Runners -- Let thirst be your guide

...ody water before there’s a significant health risk problem from dehydration, Verbalis says. “So, really, if people just do things in moderation, especially including re-hydrating by drinking, they’re not going to be at risk of either dehydration from excessive sweat losses or EAH from excessive fluid ingesti...

Researchers discover 'acquired' DNA key to certain bacterial infection

... bacterium’s resistance to antibiotics – already a problem – may be increasing. In contrast, the incidence of lung infection in patients with chronic lung diseases and cystic fibrosis is increasing. Understanding the mechanism by how M. avium penetrates the macrophage and infects humans may eventually lea...

3-D ultrasound scanner provides in-depth view of the brain

...he biomedical engineering department at Duke. "The problem is that without 3-D, you could miss something," he said. MRI machines are also expensive and require a dedicated space with special surgical tools that can be used in close proximity to the imagers' powerful magnets. Last year, the Duke team, led ...

Scientists close in on missing carbon sink

...l emissions of carbon dioxide, which is a critical problem in global warming," Stephens says. "This will help us better predict climate change and identify possible strategies for mitigating it." The missing carbon For years, one of the biggest mysteries in climate science has been the question of wh...

...rding to Komorowski. This may also overcome the problem of waste. ‘If you can genetically produce milk without fat then that may turn out to be a very good solution to what might later be a big disposal issue,’ says Komorowski. Producing skimmed and semi-skimmed milk means there is a lot of fat left over....

Mice with a migraine show signs of brain damage

The problem begins as the brain tries to recover from CSD, which throws the proportion of crucial ions like potassium and sodium out of balance, taking away the brain’s ability to function efficiently. This change in the proportion of chemicals gradually sweeps ...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...ms of nitric oxide called SNOs may be the key to a problem that has stumped physicians for years -- why specific drugs for such diseases as heart failure or asthma lose their effectiveness over time. Almost half of all drugs on the market today, as well as many hormone and neurotransmitters, target a spec...
