Climate change impacts stream life

...change on stream macroinvertebrates - animals that can be seen with the naked eye such as crustaceans, snails and larval insects including stoneflies or mayflies. Professor Ormerod, said: "Streams and rivers are likely to be highly sensitive to climate and yet long-term evidence of effects is scarce...

Role of noise in neurons

...sed. Neurons in the cerebral cortex of the brain can have a wiring density of up to 4km per mm3 by using incredibly thin axons as wires, with an average diameter of 0.3 micrometers (1ìm is one millionth of a meter). Although, as in computer chips, this miniaturization economizes on space and energy, it...

This process is called desensitization and can limit the effectiveness of many drugs, such as opiates for pain and adrenaline for asthma, and is further associated with numerous diseases including those of the cardiovascular and pulmonary systems. If activated for a long period of time the recept...

Cancer patients monitor fatigue in real time

...ause of the extreme fatigue," Hacker said. "Cancer can cause fatigue directly or indirectly by spreading to the bone marrow, causing anemia and by forming toxic substances in the body that interfere with normal cell functions.

"If novel drugs can be developed to target tumor heparan sulfate, we might be able to make a leap in cancer-fighting therapies, because several molecules critical to tumor endothelial growth also bind to heparan sulfate," Fuster said. "Altering this binding would allow...

Scientists: As rainfall changes, tropical plants may acclimate

...dreds or thousands of kilometers," Schuur said. "I can visit all of these forest sites in a single day." The scientists analyzed nitrogen isotopes in the soil and leaf samples of four plant species at each site. They learned that drier soils contained more nitrogen in the form of nitrate, while wetter...
