New clues to how sex evolves

...d to the study of meiosis because it is completely transparent and reproduces very efficiently, producing over 200 progeny within a few days. Most C. elegans are hermaphrodites, which have two X chromosomes (XX), while some individuals are males with a single X chromosome (X0). The reproductive organs contain ab...

Weighty viruses

...t. The scattered light can be detected through the transparent surfaces of the ion trap. A portion of the light is sent to a CCD camera, which records the flight path of the trapped particle. The rest of the light goes to a measuring device that precisely analyzes the scattering signal. The scattered light is di...

German researchers develop first non-invasive test to measure skin aging

...er of the skin, called the epidermis, is virtually transparent to infrared light, the infrared laser can reach the dermis with intense pulses of light without damaging the upper layers. By two different quantum processes, collagen and elastin will then respond by glowing blue and green. Currently, dermatologis...

Preliminary study finds holographic imaging system promising for cancer treatment planning

... projected onto a screen spinning inside a 24-inch transparent dome. The screen, spinning at over 900 rotations per minute, forms a detailed, holographic image that can be viewed and manipulated from any vantage point around the 360-degree dome, by any number of users. The study compared radiation treatment ...

Reversing cancer cells to normal cells

... its prolific reproduction, rapid development, and transparent embryo that develops outside the body (making it especially easy to simply watch development), and the fact it develops organs and tissues comparable to those in humans, such as heart, kidney, pancreas, bones and cartilage.) Using the zebrafish ...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

... and Technology (MOST); and CNIC will develop a transparent web service layer for data access. USM will contribute its natural compound database for use in virtual screening for new inhibitors and drug discovery. CNIC will also become the central repository for the project’s research data. The databa...

Living with water scarcity -- world must act now

...ns by the many stakeholders involved in water with transparent sharing of information. "The hope is in realizing the unexplored potential that lies in better water management along with non-miraculous changes in policy and production techniques" says Margaret Catley Carleson, Chair of the Global Water Partner...

Fast and slow -- How the spinal cord controls the speed of movement

...ng larval zebrafish (Danio rerio) because they are transparent and researchers can see their cells. Fetcho and his colleagues injected the fishes?spinal cords with a fluorescent dye, which then lit up when calcium ions flooded in as the nerve cells activated. A confocal microscope with lasers allowed the researc...

Brightening prospects of using fluorescent nanotubes in medical applications

...– the near infrared where skin and other tissue is transparent – that allows the nanotube light to stand out. Nanotubes are made entirely from graphitic carbon, which is non-toxic and, at least so far, experiments that have been done indicate that they do not damage living cells. By comparison, quantum dots,...
