Migrant labourers tell of being forced to isolate in brutal conditions as Covid wave grips region

Mr Ibori was governor of oil-producing Delta State from 1999 to 2007.

Share Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual materials go from acting like a chunk of gold to acting like a piece of wood as temperatures...

Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Magnetism drives metals to insulators in new experiment: Study provides new tools to probe novel spintronic devices An illustration of two domains (blue and orange) divided by a domain wall (white area) in a material. The magnetic order is designated with organized arrows (electron spins) while the colors represent two different domains (but the same magnetic order). In the material pictured here, the domain walls are conductive and...

Hydrogels are commonly used inside the body to help in tissue regeneration and drug delivery. However, once inside, they can be challenging to control for optimal use. A team of researchers in the Department of Biomedical Engineering at Texas A&M University is developing a new way to manipulate the gel -- by using light.

Lighting up hydrogels A new class of hydrogels leverage light for better drug delivery and regenerative medicine treatment.

(U.S. Salk Institute/Xinhua/Alamy) Researchers from the United States and China announced in April that they had created the first ever human–primate chimeras. Mixing human stem cells with macaque monkey embryos, the scientists produced creatures with cells from both species. The creation of such beings is deeply troubling, and raises questions about wh...
