Researchers advance in the development of 'papaya sugarcane'

When the papaya (Carica papaya) is ripening, its cell walls separate, making the tissue softer and more digestible. The cell contents become accessible and the sucrose in the fruit is more easily extracted. Sugarcane roots ...

How birds become male or female, and occasionally both

The highly unusual "semi-identical" Australian twins reported last week are the result of a rare event. It's thought the brother and sister (who have identical genes from their mother but not their father) developed from ...

Gene activity database could spare thousands of mice

A comprehensive database of gene activity in mice across ten disease models, which could significantly reduce animal use worldwide, has been developed by scientists at the Francis Crick Institute, which gives a full picture ...

Keeping genetic engineering localized

Genetic engineering tools that spread genes within a target species have the potential to humanely control harmful pests as well as eradicate parasitic diseases such as malaria.

An important function of non-nucleated sperm

Some animals form characteristic infertile spermatozoa called parasperm, which differ in size and shape compared to fertile sperm produced by single males. Species that have been reported to produce parasperm include snails, ...

Two-step path to shrinking worker bee gonads

The dramatic difference in gonad size between honey bee queens and their female workers in response to their distinct diets requires the switching on of a specific genetic program, according to a new study publishing March ...

When a cell's 'fingerprint' can be a weapon against cancer

A research team led by Nuno Barbosa Morais, group leader at Instituto de Medicina Molecular João Lobo Antunes (iMM) in Lisbon, computationally analysed the expression of marker genes that are associated with a "fingerprint" ...
