New book explores evolution of human reproduction

Human beings would probably be known as pilosals rather than mammals if Carl Linnaeus had not been a proponent of breast-feeding. For social and political reasons, the famed taxonomist labeled the class of animals to which humans belong with a reference to their practice of suckling their young rather than to their evolutionarily older characteristic of having hair.

This is just one of the hundreds of surprising pieces of information that readers will glean from the far-reaching and fascinating How We Do It: The Evolution and Future of Human Reproduction, a new book by Robert Martin, a member of the University’s of Chicago’s Committee on Evolutionary Biology and curator of biological anthropology at the Field Museum.

UF Scientists Find State Record 87 Eggs In Largest Python From Everglades

GAINESVILLE, Fla. — University of Florida researchers curating a 17-foot-7-inch Burmese python, the largest found in Florida, discovered 87 eggs in the snake, also a state record.

Scientists at the Florida Museum of Natural History on the UF campus examined the internal anatomy of the 164.5-pound snake Friday. The animal was brought to the Florida Museum from Everglades National Park as part of a long-term project with the U.S. Department of the Interior to research methods for managing the state’s invasive Burmese python problem. Following scientific investigation, the snake will be mounted for exhibition at the museum for about five years, and then returned for exhibition at Everglades National Park. (more…)

Insect Glands May Illuminate Human Fertilization Process

Baltimore, MD — Insect glands are responsible for producing a host of secretions that allow bees to sting and ants to lay down trails to and from their nests. New research from Carnegie scientists focuses on secretions from glands in the reproductive tract that help sperm survive and guide the sperm on the trip to fertilize an egg. The gene that controls the development of these glands in fruit flies provides important information about gland development in all insects, as well as potential clues to similar human reproductive glands. Their work is published this month in Current Biology.

When a female fruit fly receives sperm from a male fruit fly, lubricating secretions in her reproductive tract activate the sperm, store it, and guide it to fertilization. Without the aid of these secretions, sperm would not make it to the eggs. Carnegie’s Allan Spradling and Jianjun Sun demonstrated that the gene in charge of regulating the development of fruit fly secretion glands is called Hr39. It encodes a steroid receptor protein.

Turtles’ Mating Habits Protect Against Effects of Climate Change

The mating habits of marine turtle may help protect them against the effects of climate change, according to new research led by the University.

Published on 25th January 2012 in Proceedings of the Royal Society B, the study shows how mating patterns of a population of endangered green turtles may be helping them deal with the fact that global warming is leading to a disproportionate number of females being born.

The gender of baby turtles is determined by the temperature of the eggs during incubation, with warmer temperatures leading to more females being born. Higher average global temperatures mean that offspring from some populations are predominantly female. This is threatening the future of some populations and there are concerns that inbreeding within groups due to a lack of males will lead to health problems. (more…)

*Mobile Application Allows Doctors to Monitor Heart Patients*

BEIJING – 19 Aug 2010: Beijing Goodwill Information and Technology Co., Ltd., a leading provider of electronic cardiogram systems in China, and IBM (NYSE: IBM) announced the launch of the country’s first all-in-one electronic cardiogram management system in China. This system supports smarter healthcare by helping hospitals to analyze patient information generated from electrocardiography (ECG) examination reports to gain real-time insight and better detect cardiovascular diseases with more accuracy. It also empowers doctors to use mobile devices to monitor heart patients.
