Male infertility caused by a chromosomal "miscount"
During meiosis, errors in chromosome segregation lead to aneuploid gametes (with an erroneous number of chromosomes) which might result in male infertility, spontaneous abortions or affected offspring. This work describes for the first time in human spermatogenesis the...
In vitro fertilisation: enhancing cryopreservation
In the field of in vitro fertilisation, the oocytes used can be either fresh or cryopreserved. The advantages of cryopreservation are evident, but there is also a strong disadvantage: fertilisation efficiency is significantly lower. This work explores a method to...
Fishing lines kill sea turtles
Scientists from CRAM (the Foundation for the Conservation and Recovery of Marine Animals) and the Autonomous University of BArcelona have studied what happens when a loggerhead sea turtle swallows a fishhook. The researchers have reached revealing conclusions: contrary to what could be thought, the hook...
Bioremediation: getting to know the soil cleaners
Nowadays, bioremediation is one of the most viable alternatives for the recovery of contaminated soils. It consists in using biological agents, e.g. plants, that absorb pollutants and incorporate them into their organism. In this work, researchers from the UAB and the...
Invading ants
An important component in the biology of invaders is their expansion rate and pattern, both in time and space. Data on the first invasive stages are extremely difficult to obtain, although an a posteriori analysis of the expansion process is sometimes feasible.
