Biology blurs line between sexes, behaviors

Biological sex is typically understood in binary terms: male and female. However, there are many examples of animals that are able to modify sex-typical biological and behavioral features and even change sex. A new study, ...

Algal blue light switch control of electrical excitation in plants

Optogenetics denotes the manipulation of cellular processes by light-based biological techniques. An international research team led by the W├╝rzburg plant scientists Rainer Hedrich, Georg Nagel and Dirk Becker has succeeded ...

Using porous crystals to harvest light

Drawing inspiration from photosynthesis, KAUST researchers have developed a new spin on metal organic frameworks (MOFs) that could help solar cells to gather more energy from the Sun.

Lead poisoning could reduce gene expression in humans

Scientists have unveiled a correlation between high blood lead levels in children and methylation of genes involved in haem synthesis and carcinogenesis, indicating a previously unknown mechanism for lead poisoning.

Molecular forces: The surprising stretching behavior of DNA

When large forces act on a heavy beam, for example, in bridge construction, the beam will be slightly deformed. Calculating the relationship between forces, internal stresses and deformations is one of the standard tasks ...
