Heat-stressed cows spend more time standing

Bovine behavior changes as the day heats up

2013-03-12
(Press-News.org) Des Moines, IA – A new study by researchers at the University of Arizona and Northwest Missouri State University shows that standing and lying behavior can predict heat stress in cows.

In a presentation at the 2013 ADSA Midwest Branch / ASAS Midwestern Section Meeting, Dr. Jamison Allen explained that predicting heat stress is vital for keeping cows healthy and productive. Cows will pant, eat less and produce less milk when their core body temperature increases.

Allen said cows prefer standing to lying on hot days. Cows stand to allow more of their surface area to disperse heat into the air. Allen and his colleagues were curious to see if standing behavior could be used to predict core body temperature.

The researchers used two tools to study the relationship between behavior and temperature. They fitted each cow with an intra-vaginal sensor to measure core body temperature. They also fitted each cow with a special leg sensor to measure the angle of the leg and track whether the cow was standing or lying.

After comparing data from cows in Arizona, California and Minnesota, the researchers concluded that standing behavior and core body temperature are strongly correlated. Allen said cows stood for longer bouts of time as their core body temperatures rose from 101 degrees Fahrenheit to above 102 degrees.

"We can predict the animal's behavior to stand according to their core temperature," Allen said.

According to Allen, dairy producers could use standing behavior to improve well being and efficiency in their herds. He said producers could use coolers and misters to target a specific core body temperature. By encouraging cows to lie down, producers will also help their cows conserve energy.

Allen recommended future studies to see how cows respond to different cooling systems. He said researchers could also study cow behavior related to humidity.

Allen's abstract was titled "Effect of core body temperature or time of day on lying behavior of lactating dairy cows." The research was presented Mar. 12 as part of the Animal Behavior, Housing and Well Being Oral Session. ### END

Ruptured aneurysm has lasting impact on quality of life

2013-03-12
Philadelphia, Pa. (March 12, 2013) – Ten years after stroke caused by a ruptured aneurysm of the brain, surviving patients have persistent difficulties in several areas affecting quality of life, reports a study in the March issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The long-term impact of ruptured aneurysms causing subarachnoid hemorrhage (SAH) highlights the need for "survivorship care plans" comparable to those made for long-term cancer ...

The nose's unheralded neighbor

The noses unheralded neighbor
2013-03-12
Pity the poor maxillary sinuses. Those bulbous pouches on either side of the human nose are known more for trapping mucus and causing sinus infections than anything else. They were thought to be an evolutionary relic of our distant past, with little known present value. Yet researchers led by the University of Iowa believe the unheralded maxillary sinuses play a fortuitous, integral role in the shape and function of the human nose, even today. After studying faces of African and European origin, the team has concluded that the maxillary sinuses act as a cushion of sorts, ...

Tickling the brain with magnetic stimulation improves memory in schizophrenia

2013-03-12
Philadelphia, PA, March 12, 2013 – Cognitive impairments are disabling for individuals with schizophrenia, and no satisfactory treatments currently exist. These impairments affect a wide range of cognition, including memory, attention, verbal and motor skills, and IQ. They appear in the earliest stages of the disease and disrupt or even prevent normal day-to-day functioning. Scientists are exploring a variety of strategies to reduce these impairments including "exercising the brain" with specially designed computer games and medications that might improve the function ...

Antibiotic-resistant strain of E. coli increasing among older adults and residents of nursing homes

2013-03-12
Antibiotic-resistant Escherichia coli (E. coli) continues to proliferate, driven largely by expansion of a strain of E. coli know as sequence type ST131. A new study points to hospitals and long-term care facilities (LTCF) as settings in which this antibiotic-resistant strain is increasingly found. The study is published in the April issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. E. coli is the most common gram-negative pathogen, causing both gastrointestinal disease and extraintestinal infections ...

Infants prefer individuals who punish those not like themselves, Yale researchers find

2013-03-12
Infants as young as nine months old prefer individuals who punish those who are not like them, and this seemingly innate mean streak grows stronger in the next five months of life, a study by researchers at Yale University has found. Babies, like adults, prefer individuals who like the same things they do. A new study reports that they want individuals who share their tastes to be treated well by others, but want those whose tastes differ from their own to be treated badly. The study of 200 nine- and 14-month-old infants was published online in Psychological Science, ...

New distance record for 400 Gb/s data transmission

New distance record for 400 Gb/s data transmission
2013-03-12
As network carriers debate the next Ethernet standard—and whether transmission speeds of 400 gigabit per second or 1 terabit per second should be the norm—engineers are working on new measures to squeeze next-generation performance out of current-generation systems. To that end, a team from AT&T has devised a new patent pending technique enabling tuning of the modulation spectral efficiency, which allows, for the first time, 400 Gb/s signals to be sent over today's 100 gigahertz-grid optical networks over ultra-long distances. Spectral efficiency is the information rate ...

Job burnout can severely compromise heart health

Job burnout can severely compromise heart health
2013-03-12
Americans work longer hours, take fewer vacation days, and retire later than employees in other industrialized countries around the globe. With such demanding careers, it's no surprise that many experience job burnout — physical, cognitive, and emotional exhaustion that results from stress at work. Researchers have found that burnout is also associated with obesity, insomnia, and anxiety. Now Dr. Sharon Toker of Tel Aviv University's Faculty of Management and her fellow researchers — Profs. Samuel Melamed, Shlomo Berliner, David Zeltser and Itzhak Shpira of TAU's Sackler ...

Ultra-high-speed optical communications link sets new power efficiency record
2013-03-12
Ultrafast supercomputers that operate at speeds 100 times faster than current systems are now one step closer to reality. A team of IBM researchers working on a U.S. Defense Advanced Research Projects Agency (DARPA)-funded program have found a way to transmit massive amounts of data with unprecedentedly low power consumption. The team will describe their prototype optical link, which shatters the previous power efficiency record by half at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) in Anaheim, Calif. ...

New automated process simplifies alignment and splicing of multicore optical fibers

New automated process simplifies alignment and splicing of multicore optical fibers
2013-03-12
New multicore optical fibers have many times the signal-carrying capacity of traditional single-core fibers, but their use in telecommunications has been severely restricted because of the challenge in splicing them together-- picture trying to match up and connect two separate boxes of spaghetti so that all of the noodles in each box are perfectly aligned. Now, a new splicing technique offers an automated way to do just that, with minimal losses in signal quality across the spliced sections. The method will be described at the Optical Fiber Communication Conference and ...

Penn study: Financial incentives affect prostate cancer treatment patterns

2013-03-12
Philadelphia - According to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania, prostate cancer patients of urologists who own expensive radiation equipment are more likely to receive radiation treatment in lieu of surgery than patients treated by urologists without an ownership stake in the equipment. The study, now available online in the Journal of Urology, found that integrated prostate cancer centers (IPCCs), where urology and radiation oncology practices are combined, use expensive radiation-based treatments at higher rates ...
