Electrical Current Stemming From Algae

Stanford scientists have harnessed a tiny electrical current from algae cells. They found it at the very source of energy production – photosynthesis - and it may be the first step toward generating high-efficiency bioelectricity that doesn't give off carbon dioxide as a byproduct.

Should human genes be patentable?

This week's question concerns the issue of gene patents. While some in the scientific community believe that human genes should not be exploited for commercial gain, others argue that a patent is a reward for years of expensive research that moves science forward. What do you think? Should human genes be patentable?

Moving Toward a Carbon-based Solar Cell

To make large sheets of carbon available for light collection, Indiana University Bloomington chemists have attached what amounts to a 3D bramble patch to each side of the carbon sheet. The scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, which is a first.

Princeton's Plastics Hold Potential for Lowering Cost of Solar Panels

Princeton University engineers have developed translucent, malleable, and electricity-conducting plastics, which could represent a low-cost alternative to indium tin oxide (ITO) - an expensive conducting material currently used in solar panels.

New Path to Solar Energy Via Solid-State Photovoltaics

Berkeley Lab researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new route to energy production overcomes the bandgap voltage limitation that continues to plague conventional solid-state solar cells.

The Smallest Superconductor in the World

Scientists have discovered the world’s smallest superconductor - a sheet of four pairs of molecules less than one nanometer wide. The Ohio University-led study provides the first evidence that nanoscale molecular superconducting wires can be fabricated, which could be used for nanoscale electronic devices and energy applications.

Is cold fusion possible?

This week's question concerns the concept of cold fusion. Cold fusion refers to the nuclear fusion of atoms at conditions close to room temperature, which (theoretically) has the potential to produce an abundant source of energy at low cost. Once thought of as "junk science," cold fusion is slowly gaining acceptance in the mainstream scientific community. What do you think? Is cold fusion possible?
