London, April 2 : Scientists have created tiny microbial fuel cells by encapsulating yeast cells in a flexible capsule, which can generate power from a drop of human blood plasma, and might one day energize implants such as pacemakers.
According to a report in New Scientist, the cells, developed by a team at the University of British Columbia (UBC) in Vancouver, Canada, can feed on the glucose in human blood.
Washington, April 2 : University of Washington experts have warned that the way modern technology has been breaking people's connections with the natural world may give rise to a major psychological problem.
"We are a technological species, but we also need a deep connection with nature in our lives," said Peter Kahn, a UW developmental psychologist.
Kahn and two of his UW graduate students, Rachel Severson and Jolina Ruckert, explored how humans connect with nature and technological nature.
London, April 2: Archaeological excavations in the ancient region of Baktria in Afghanistan have revealed a unique marble slab with the image of Alexander the Great and a passage of an inscription.
The slab represents an ancient king on a horse heading Macedonian cavalry and Macedonian phalanx at the background.
Washington, April 2 : A new research has shown that for millions of years carbon dioxide (CO2) has been stored safely and naturally in underground water in gas fields saturated with the greenhouse gas, a finding that brings carbon capture and storage a step closer.
Some models predict that CO2 would react with rock minerals to form new carbonate minerals, while others suggest that the gas dissolves into the water.
Real studies to support either of these predictions have, until now, been missing.
Washington, Apr 2 : A research team, including an Indian-origin boffin, has suggested that radiation treatment directly to the ovaries should be avoided in female cancer patients of reproductive age because there is a direct relationship between certain types of radiation therapy and fertility problems.
Radiation therapy to the pelvic region can cause ovarian failure or result in damage that makes the uterus unable to accommodate the growth of a foetus.
These effects are not a great concern to cancer patients past their reproductive years, but due to the growing number of paediatric and young-adult cancer survivors, these effects are increasingly relevant.
Washington, Apr 2 : A new study from University of Cambridge has provided new evidence that the human brain lives "on the edge of chaos", at a critical transition point between randomness and order.
The researchers claim to have identified a mechanism called self-organized criticality, where systems spontaneously organize themselves to operate at a critical point between order and randomness.
This phenomenon might occur from complex interactions in many different physical systems, including avalanches, forest fires, earthquakes, and heartbeat rhythms.
