A low-testosterone man newly married to a high-testosterone woman might seem destined to be henpecked but a Penn State study found that such a coupling actually produced a marriage where the wife provided better social support for her mate.

Dr. Catherine Cohan, assistant professor of human development and family studies, says, “It’s not necessarily the case that higher testosterone is all bad. Testosterone is related to assertiveness which can be good or bad depending on whether it is m

Study Sheds light on HIV mutation process; May help guide AIDS vaccine development

Scientists in California have provided the first detailed look at how human antibodies, proteins critical for the body’s defense against invading pathogens, may actually drive human immunodeficiency virus (HIV) to mutate and escape detection by the immune system. The findings, reported online March 18 in the Proceedings of the National Academy of Sciences, may be key in efforts to develop an effective

A deactivation of the immune system in patients infected with HIV could be one way to inhibit progression to the immunodeficiency diseases associated with AIDS, researchers from UT Southwestern Medical Center at Dallas and Emory University report.

A study comparing the effects of immunodeficiency virus in humans to its effects in sooty mangabey monkeys, which do not become ill when infected, revealed two major differences in the monkeys’ responses to the infection. The findings could o

The development of a new generation of membranes based on conducting polymers has been the subject of a recent line of research in the Department of New Materials at CIDETEC, in association with the LEIA Technological Centre.

This involves a field of work wherein the excellent advantages presented by electro-dialysis conventional membranes (continuous separation, low energy consumption, ease of combination with other separation processes, absence of additives) are combined with other, highl

Opiates and cannaboids, apart from being drugs, have curative properties. Thus, opiates (morphine, methadone, etc.) have been used for some time as a pain-reducer and many cannaboids have also analgesic properties.

Regarding their curative aspects, it is very important to know the effects produced after a prolonged period of treatment. Carrying out this analysis with opiates and cannabinoids, two important problems arise: given that they are drugs, they create psychological dependency and, i

A biological process using three different types of fungi to control common plant diseases and mite pests has been developed by researchers at the Hebrew University’s Faculty of Agricultural, Food and Environmental Quality Sciences in Rehovot.

Use of these fungi enables crops to overcome such plant diseases and pests without having to apply environmentally-polluting chemicals, said Abraham Sztejnberg, the Hebrew University’s Francis Ariowitsch Professor of Agriculture, a member of the resear
