Adults living with children eat more fat than do other adults

Adults living with children eat more saturated fat — the equivalent of nearly an entire frozen pepperoni pizza each week — than do adults who do not live with children, according to a University of Iowa and University of Michigan Health System study.

The Eocene Epoch: Ancient insects used advanced camouflage

A fossil of a leaf-imitating insect from 47 million years ago bears a striking resemblance to the mimickers of today.

The discovery represents the first fossil of a leaf insect (Eophyllium messelensis), and also shows that leaf imitation is an ancient and successful evolutionary strategy that has been conserved over a relatively long period of time.

Scientists make simulated lunar soil

Life is tough for a humble grain of dirt on the surface of the Moon. It’s peppered with cosmic rays, exposed to solar flares, and battered by micrometeorites–shattered, vaporized and re-condensed countless times over the billions of years. Adding insult to injury, Earthlings want to strip it down to oxygen and other elements for “in situ resource utilization,” or ISRU, the process of living off the land when NASA returns to the Moon in the not-so-distant future.

FDA Says Cloned Meat A-OK

The U.S. Food and Drug Administration (FDA) today issued three documents on the safety of animal cloning — a draft risk assessment; a proposed risk management plan; and a draft guidance for industry. The draft risk assessment finds that meat and milk from clones of adult cattle, pigs and goats, and their offspring, are as safe to eat as food from conventionally bred animals. The assessment was peer-reviewed by a group of independent scientific experts in cloning and animal health. They agreed with the methods FDA used to evaluate the data and the conclusions set out in the document.

Ancient text leads to potential new anti-bacterial

A unique Mayo Clinic collaboration has revived the healing wisdom of Pacific Island cultures by testing a therapeutic plant extract described in a 17th century Dutch herbal text for its anti-bacterial properties. Early results show that extracts from the Atun tree effectively control bacteria that can cause diarrhea, as claimed by naturalist Georg Eberhard Rumpf, circa 1650. He documented his traditional healing methods in the book Ambonese Herbal.

How to really be the biggest loser

I am the statistic – me and the rest of the emergency medicine side show freaks that get bounced on the LAST TEST after passing every other hurdle in a medical career (MCAT, medical school, USMLE 1, 2, 3 and the written board exam).

Device Prevents or Reduces Brain Damage in Infants

The Food and Drug Administration (FDA) today approved a first-of-a-kind medical device for the treatment of babies born with moderate to severe hypoxic-ischemic encephalopathy (HIE), a potentially fatal injury to the brain caused by low levels of oxygen. The Olympic Cool-Cap system is designed to prevent or reduce damage to the brains of these patients by keeping the head cool while the body is maintained at a slightly below-normal temperature. The Cool-Cap is manufactured by Olympic Medical Corporation, a subsidiary of Natus Medical Incorporated of San Carlos, Calif.

3-D scaffold for growing stem cells

Stem cells grew, multiplied and differentiated into brain cells on a new three-dimensional scaffold of tiny protein fragments designed to be more like a living body than any other cell culture system. An MIT engineer and Italian colleagues will report the invention-which may one day replace the ubiquitous Petri dish for growing cells-in the Dec. 27th issue of the PLoS ONE. Shuguang Zhang, associate director of MIT’s Center for Biomedical Engineering, is a pioneer in coaxing tiny fragments of amino acids called self-assembling peptides to organize themselves into useful structures.

Pet owners are sick more often, exercise less than other working-aged people

A common perception is that pet owner is a young person who is full of action, exercises a lot, and actively plays with a pet, particularly with a dog. The reality is different, however. The association of pet ownership and health of working aged Finns (20-54 years of age) was studied at the University of Turku as part of a large research project entitled Health and Social Support (HeSSup). The findings were published in PLoS ONE, the new international online publication of the Public Library of Science.

How does a zebrafish grow a new tail?

If a zebrafish loses a chunk of its tail fin, it’ll grow back within a week. Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of cells and is a very intricate structure. It is the fish version of an arm or leg.

Western wildfires tied to Atlantic surface temps

Western U.S. wildfires are likely to increase in the coming decades, according to a new tree-ring study led by the University of Comahue in Argentina and involving the University of Colorado at Boulder that links episodic fire outbreaks in the past five centuries with periods of warming sea surface temperatures in the North Atlantic.

The Mathematics of Cloaking

The theorists who first created the mathematics that describe the behavior of the recently announced “invisibility cloak” have revealed a new analysis that may extend the current cloak’s powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.

CO2 Emissions Will Shrink Earth’s Outer Atmosphere by 2017

Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth’s outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU).

Extended-Release Invega Approved for Schizophrenia

The Food and Drug Administration has approved Invega (paliperidone) extended-release tablets for the treatment of schizophrenia. Paliperidone is a new molecular entity, which means this medication contains an active substance that has never before been approved for marketing in any form in the United States. Paliperidone is the principal active metabolite of risperidone, a marketed drug for treating schizophrenia.

First-borns get more quality time with parents

First-born children get more quality time with parents than subsequent children, a Cornell study shows. Using data from the American Time Use Survey, Joseph Price, a graduate student in economics at Cornell, found that a first-born child receives 20-30 more minutes of quality time each day with a parent than a second-born child of the same age from a similar family.

Prompting men to have syphilis tests

An innovative social marketing campaign called “Healthy Penis,” which used humorous cartoon strips to encourage gay and bisexual men in San Francisco to get checked for syphilis, was associated with an increase in syphilis tests, according to evaluations published in PLoS Medicine.
