Cattle seem to have an internal compass–one that’s messed up by power lines

July 2009

1 July 2009—Maybe cows are most comfortable—and willing to produce more milk—when their bodies are aligned along a north-south axis. Sound far-fetched?

A team of researchers from Germany and the Czech Republic has already discovered that, all factors being equal, cattle and two species of deer tend to align themselves along a north-south axis using some innate magnetic sense, and that this preferred alignment is disturbed when they graze under high-voltage power lines. In the next step, in their ongoing study of magnetoreception, the researchers hope to learn more about the physiological impact of magnetic fields on these and other animals.

“It could very well be that Earth’s magnetic field has an effect on physiological processes—like brain waves or blood circulation—and that this magnetic alignment could make some bodily processes function better,” says Sabine Begall, a member of the research team headed by Hynek Burda, a professor of zoology at Germany’s University of Duisburg-Essen. “We don’t know. We’re still at a very early stage in our research.”

For their research of magnetoreception and its role in spatial orientation, Burda and his team used satellite and aerial images from Google Earth to analyze cattle in open pastures. When a herd was at least 150 meters away from power lines, the researchers detected a significant alignment of the cattle along the north-south axis. By contrast, images of cattle grazing within 50 meters of high-voltage overhead power lines showed no preferred body alignment.

Interestingly, cows grazing directly underneath east-west power lines tended to align along the power lines, whereas those under lines running north-south, northwest-southeast, or northeast-southwest showed random alignments.

The researchers think they have an answer for the deviation in the east-west alignment: The alternating magnetic field produced by the power lines is perpendicular to the power lines and thus parallel to Earth’s magnetic field. The increased intensity, the researchers assume, could induce a shift in body alignment. A similar phenomenon has been observed in experiments on magnetoreceptive birds.

The magnetic sensing discovery for cattle also applies to roe deer and red deer, which the researchers observed firsthand. The team noticed that herds staying near power lines were randomly aligned and, like cows, had a greater north-south alignment when grazing beyond 150 meters of the cables.

Several species of birds, fish, and insects, as well as some small mammals, such as bats and rodents, are known to have magnetic sensing systems. Now that Burda and his team have shown that larger mammals are also able to sense magnetic fields, the researchers are curious to know why they have this capability and how they use it. Among the possible benefits magnetoreception might hold for herds of cows and deer is an ability to synchronize their direction to graze more efficiently, escape predators more effectively, or just simply feel more comfortable.

It’s not yet known how cattle feel the magnetic field. One theory focuses on magnetite crystals that magnetically receptive trout, mole rats, and pigeons have in their noses, eyes, or beaks. Another is the “radical pair” hypothesis, which involves a light-sensitive molecule called cryptochrome, used by photoreceptors in the eyes to sense blue light. Through cryptochrome, animals may actually be able to see magnetic fields as visual patterns.

In addition to physiological functions, Burda and his team plan to study magnetic alignment across diverse cattle breeds and species and the other factors that may influence it. They also want to look more closely at the possible impact of the geometry of power towers and the flow of electricity, and correlate the behavior of cattle and other animals with the actual measured values of the magnetic fields.

The Effects Of Radiation In The Cause Of Cancer

By Paul Fitzgerald

Cancer is, unfortunately, spreading in the modern society. Nearly all cancer forms are increasing when it comes to incidence, i.e. new cases/year (cf. Hallberg & Johansson 2002a).

It could recently be read in the BBC News that skin cancer is rising in young adults, and Sara Hiom, head of the health information at Cancer Research UK said, when interviewed, that “Non-melanoma cancers are rising at an alarming rate”.

Non-melanoma cancers are rising at an alarming rate. 

More and more research efforts goes into understanding the molecular mechanisms behind these various progressive cancer forms, and much more money is spent on finding new drugs to treat patients. However, oddly enough, very little is spent on understanding the actual causes for cancer.

Among such possible causative agents, more and more focus is nowadays put on modern gadgets, such as mobile telephones and computers, and their chemical and physical emissions, including flame retardants and electromagnetic non-ionising radiation. 

Childhood leukemia was early connected to power-frequent magnetic fields already in the pioneering work by Wertheimer and Leeper (1979), and more recently Scandinavian scientists have identified an increased risk for acoustic neuroma (i.e., a benign tumor of the eighth cranial nerve) in cell phone users, as well as a slightly increased risk of malignant brain tumors such as astrocytoma and meningioma on the same side of the brain as the cell phone was habitually held (Hardell et al. 1999, 2004, 2005; Lonn et al. 2004). 

In addition, a clear association between adult cancers and FM radio broadcasting radiation has been noticed, both in time and location (Hallberg & Johansson 2002b, 2004, 2005a). Initial studies on facial nevi indicates that nowadays also young children can have a substantial amount of these.

If it can be shown that radiofrequent radiation is not correlated with child cancers the current focus on low-frequency electromagnetic fields can continue. If there is also a radiofrequent and/or microwave correlation then this must be considered in future research as well as in today’s preventive work. 

Most recently, Dr. Djemal Beniashvili and other scientists at the Edith Wolfson Medical Center in Holon, Israel, have demonstrated a possible link between exposure to power-frequent electromagnetic fields and breast cancer in elderly women (Beniashvili et al. 2005).  

They compared the breast cancer rates in elderly women from an earlier period (1978-1990) to a more recent period (1991-2003), which has been characterized by a much more extensive use of personal computers (more than 3 hours a day), mobile telephones, TV sets, and other household electrical appliances. They used available medical records extending over a period of 26 years, involving the analysis of more than 200,000 samples. 

Most recently a possible link has been demonstrated between exposure to power-frequent electromagnetic fields and breast cancer in elderly women 

Among the elderly women who developed breast cancer in the first time frame, 20 percent were regularly exposed to power-frequent fields.  

But in the more modern period 51 percent were so exposed, mainly through the use of personal computers. The authors concluded: “There was a statistically significant influence of electromagnetic fields on the formation of all observed epithelial mammary tumours in the second group.”

This represented a more than two-fold increase, which was considered highly significant (cf. Beniashvili et al. 2005). 

Of course, many other environmental factors have changed during the period 1978-1990, but increased environmental exposure to power-frequent fields is among the more conspicuous changes to have taken place. Naturally, there are many aspects of this question that remain to be clarified, and, from a scientific point of view, it is far from conclusively settled.
