Blue whale behavior affected by man-made noise

Blue whale vocal behavior is affected by man-made noise, even when that noise does not overlap the frequencies the whales use for communication, according to new research published Feb. 29 in the open access journal PLoS ONE. The whales were less likely to emit calls when mid-frequency sonar was present, but were more likely to do so when ship sounds were nearby, the researchers report. The study was conducted in the Pacific Ocean off the coast of Southern California by Mariana Melcon and her colleagues from University of California San Diego. Blue whale vocalizations ...

Snow leopard diet determined by DNA analysis of fecal samples

Knowledge about animal diet can inform conservation strategy, but this information can be difficult to gather. A new DNA-based method, which analyzes genetic material from feces, could be a useful tool, and researchers have shown its utility to characterize the diet of snow leopards in Mongolia. The full results are reported Feb. 29 in the open access journal PLoS ONE. Analysis of DNA from 81 fecal samples showed that the leopards ate mostly Siberian ibex, followed by domestic goats and wild sheep. Most of the animals eaten were wild (79 %), with a relatively low proportion ...

Triceratops controversy continues

Millions of years after its extinction, Triceratops is inciting controversy about how to classify the ancient animals. New analysis, published Feb. 29 in the open access journal PLoS ONE, suggests that the specimens in question should be classified into two separate groups, Triceratops and Torosaurus, and are not individuals of different ages from the same genus, as others have proposed. The researchers, led by Nicholas Longrich of Yale University, performed detailed morphological and computational analysis of 35 specimens and found evidence that Triceratops and Torosaurus ...

VLT rediscovers life on Earth By looking at the moon

"We used a trick called earthshine observation to look at the Earth as if it were an exoplanet," says Michael Sterzik (ESO), lead author of the paper [1]. "The Sun shines on the Earth and this light is reflected back to the surface of the Moon. The lunar surface acts as a giant mirror and reflects the Earth's light back to us — and this is what we have observed with the VLT." The astronomers analyse the faint earthshine light to look for indicators, such as certain combinations of gases in the Earth's atmosphere [2], that are the telltale signs of organic life. This method ...

Blockade of learning and memory genes may occur early in Alzheimer's disease

A repression of gene activity in the brain appears to be an early event affecting people with Alzheimer's disease, researchers funded by the National Institutes of Health have found. In mouse models of Alzheimer's disease, this epigenetic blockade and its effects on memory were treatable. "These findings provide a glimpse of the brain shutting down the ability to form new memories gene by gene in Alzheimer's disease, and offer hope that we may be able to counteract this process," said Roderick Corriveau, Ph.D., a program director at NIH's National Institute of Neurological ...

Fashion and Breast Augmentation

Some women considering breast augmentation worry that, after having this procedure, styles will change and they will, of a sudden, be out of fashion. It is important to remember that fashions do change. Every year there are new clothing options, often in flattering shapes and colors. What is more likely is that smaller, undefined breasts actually inhibit you form wearing the latest fashions and may completely eliminate many clothing options. Style and fashion are not the same thing. Breast augmentation isn't about fashion, it's about style; your style to be specific. ...

Reawakening neurons: Researchers find an epigenetic culprit in memory decline

In a mouse model of Alzheimer's disease, memory problems stem from an overactive enzyme that shuts off genes related to neuron communication, a new study says. When researchers genetically blocked the enzyme, called HDAC2, they 'reawakened' some of the neurons and restored the animals' cognitive function. The results, published February 29, 2012, in the journal Nature, suggest that drugs that inhibit this particular enzyme would make good treatments for some of the most devastating effects of the incurable neurodegenerative disease. "It's going to be very important ...

Federal Trucking Laws

Victims of truck accidents often find themselves mired in a frustrating and complex legal process when trying to seek compensation. Part of this has to do with the number of parties that may be held accountable in a truck accident. The driver, the trucking company, the personnel who loaded the trailer, and even truck part manufacturers can be held responsible for damages in a truck accident depending on the circumstances. When you hire a truck accident attorney, one of the first things he or she will look for is potential violations of federal trucking laws. The Federal ...

Skin infection sheds light on immune cells living in our skin

BOSTON, MA—Very recently, researchers discovered an important population of immune cells called memory T cells living in parts of the body that are in contact with the environment (e.g., skin, lung, GI tract). How these "resident" memory T cells are generated was unknown, and their importance with regard to how our immune system remembers infection and how it prevents against re-infection is being studied intensively. Now, a study by a Brigham and Women's Hospital (BWH) research team led by Xiaodong Jiang, PhD, research scientist and Thomas S. Kupper, MD, Chair of ...

Measuring blood flow to monitor sickle cell disease

(Cambridge, Mass.) -- More than 60 years ago, scientists discovered the underlying cause of sickle cell disease: People with the disorder produce crescent-shaped red blood cells that clog capillaries instead of flowing smoothly, like ordinary, disc-shaped red blood cells do. This can cause severe pain, major organ damage and a significantly shortened lifespan. Researchers later found that the disease results from a single mutation in the hemoglobin protein, and realized that the sickle shape — seen more often in people from tropical climates — is actually an evolutionary ...

When continents collide: A new twist to a 50 million-year-old tale

ANN ARBOR, Mich. --- Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau. India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end and why. She conducted a study that led to surprising findings that could add a new wrinkle to the well-established theory of plate tectonics – the dominant, unifying theory of geology. "The exciting ...

China's urbanization unlikely to lead to fast growth of middle class: UW geographer

The number of people living in China's cities, which last year for the first time surpassed 50 percent of the national population, is considered a boon for the consumer goods market. That is based on the assumption that there will be more families with more disposable income when poor farmers from China's countryside move to cities and become middle-class industrial and office workers. But the assumption overlooks a policy from the era of Chinese leader Mao Zedong that restricts the upward mobility of its rural citizens, says a University of Washington geographer. This ...

A 2-pronged attack: Why loss of STAT1 is bad news

The so-called signal transducers and activators of transcription (STATs) are involved in the regulation of cell division but details of their functions remain a matter of conjecture. In the development of breast cancer, the role of STAT1 is particularly interesting as high levels of STAT1 activity are known to be correlated with a better prognosis for breast cancer patients. There is a considerable body of evidence that STAT1 can act to suppress tumour growth in breast cancer but how does it function? Important clues are provided by the latest results of Christine Schneckenleithner ...

Inherited epigenetics produced record fast evolution

The domestication of chickens has given rise to rapid and extensive changes in genome function. A research team at Linköping University in Sweden has established that the changes are heritable, although they do not affect the DNA structure. Humans kept Red Junglefowl as livestock about 8000 years ago. Evolutionarily speaking, the sudden emergence of an enormous variety of domestic fowl of different colours, shapes and sizes has occurred in record time. The traditional Darwinian explanation is that over thousands of years, people have bred properties that have arisen through ...

Legal Protections Against Pregnancy Discrimination in the Workplace

A business executive is passed over for an important assignment after she announces her pregnancy. A single mother is verbally harassed by co-workers about her pregnancy. A waitress is denied extra rest breaks medically needed to help keep her pregnancy-induced high blood pressure under control. An office worker is hired, but the employer changes its mind after finding out she is expecting. All of these situations constitute potentially illegal pregnancy discrimination under federal employment law, and under the discrimination laws of most states. Unfortunately, these ...

Young people face double penalty in a slow job market

The latest official unemployment figures show that unemployment among young people has soared to 22.3 per cent, higher than the recession of the 1990s, while the overall unemployment rate is nine per cent. New research from Understanding Society, a study of more than 40,000 UK households, has examined what is driving this uneven employment pattern and finds that young people suffer from a 'double-penalty' in their attempts to find and keep a job. The rise in youth unemployment figures is due to young people being more likely than older workers to be laid off, thus swelling ...

Social Host Law Hold Adults Liable for Teen Drinking

In 1996, following a graduation party in Massachusetts, an 18-year old boy was involved in a fatal car accident after the car he was driving slammed into a telephone pole. At the time of the accident, the boy's blood alcohol content (BAC) was twice the legal limit for adults of .08. An adult hosted the graduation party, though the adult did not provide the alcohol directly to the minor. And because he did not directly provide the alcohol, the host was acquitted of any wrongdoing. While it was a tragedy, the teenager's death and the subsequent acquittal of the party ...
