Slinky-like 'Hyperlens' Enables Observation of Single Molecules

May 25, 2015 7:00 am | by Univ. at Buffalo | News | Comments

It looks like a Slinky suspended in motion. Yet this photonics advancement– called a metamaterial hyperlens– doesn’t climb down stairs. Instead, it improves our ability to see tiny objects. The hyperlens may someday help detect some of the most lethal forms of cancer.

Good Sound Quality Definition Differs by Culture

May 22, 2015 1:30 pm | by Acoustical Society of America | News | Comments

Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play in in the Grand Canyon, and the sound will crash against the rock walls. The disparity is clear— to the modern listener, the instrument belongs in an auditorium. But, in the past, people sought echoes. The response of audiences and performers to acoustic characteristics is a function of their worldview, and it is as fluid as the environment they inhabit.

Protein-packed Snacks Aid Appetite Control in Teens

May 22, 2015 7:00 am | by Univ. of Missouri | News | Comments

Although eating high-protein, afternoon snacks can aid appetite control in adults, little information exists to guide parents on what types of snacks might benefit their adolescent children. Now, researchers have found that afternoon snacking, particularly on high-protein soy foods, reduces afternoon appetite, delays subsequent eating and reduces unhealthy evening snacking in teenagers.

Contrary to public perception and horrific cases that make headlines, serious mental problems are declining among the nation's youth, and there has been a big rise in how many are getting help, a new study finds. The study is mostly good news: more children and teens are taking mental health medicines than ever before, but more also are getting therapy, not just pills.

Donate Your Body to Science, Without Dying First

May 21, 2015 7:00 am | by Michelle Taylor, Editor-in-Chief | Blogs | Comments

Typically, when someone chooses to donate their body to science, it’s as a cadaver. While cadavers are great learning tools, there’s something to be said for having access to living, breathing humans. Now, a group of scientists has discovered a way to circumvent the “you must be dead first” rule.

Laboratory Equipment’s scientist of the week is Juan Carlos Izpisua Belmonte from the Salk Institute for Biological Studies. He and a team studying a rare premature aging disease, Werner syndrome, have found what they believe to be one of the underlying causes of normal human aging.  

Skipping Meals May Lead to Abdominal Weight Gain

May 20, 2015 3:00 pm | by Ohio State Univ. | News | Comments

A new study in animals suggests that skipping meals sets off a series of metabolic miscues that can result in abdominal weight gain. In the study, mice that ate all of their food as a single meal and fasted the rest of the day developed insulin resistance in their livers. When the liver doesn’t respond to insulin signals telling it to stop producing glucose, that extra sugar in the blood is stored as fat.

Fifty Years of Research Answers the Question of Nature or Nurture

May 20, 2015 9:34 am | by Univ. of Queensland | News | Comments

One of the great tussles of science– whether our health is governed by nature or nurture– has been settled, and it is effectively a draw. A review studied almost every twin study across the world from the past 50 years, involving more than 14.5 million twin pairs. The study revealed, on average, the variation for human traits and diseases is 49 percent genetic, and 51 percent because of environmental factors and/or measurement errors.

Shared Thoughts Lead to Shared Speech

May 20, 2015 7:00 am | by Univ. of Rochester | News | Comments

As social creatures, we tend to mimic each other’s posture, laughter and other behaviors, including how we speak. Now, a new study shows that people with similar views tend to more closely mirror, or align, each other’s speech patterns. In addition, people who are better at compromising align more closely.

Stutterers Have a Hard Time Hearing a Beat

May 20, 2015 7:00 am | by Michigan State Univ. | News | Comments

Stuttering may be more than a speech problem. For the first time, researchers have found that children who stutter have difficulty perceiving a beat in music-like rhythms, which could account for their halting speech patterns.  

'Redesigned' Antibodies May Neutralize HIV

May 20, 2015 7:00 am | by Vanderbilt Univ. | News | Comments

With the help of a computer program called "Rosetta," researchers have "redesigned" an antibody that has increased potency and can neutralize more strains of the AIDS-causing human immunodeficiency virus (HIV) than can any known natural antibody. The find suggests that computer-redesigned antibodies may speed the search for an effective therapy or vaccine for a virus that so far has eluded all attempts to eradicate it.

Cancer Drugs May Treat Down Syndrome, Brain Disorders

May 20, 2015 7:00 am | by Univ. of Michigan | Videos | Comments

A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers have found. They showed that giving the leukemia drugs nilotinib or bafetinib to fly larvae with the equivalent of Fragile X prevented the wild overgrowth of neuron endings associated with the disorder.

Pulsed Electric Fields Can Preserve Milk

May 19, 2015 3:18 pm | by American Friends of Tel Aviv Univ. | News | Comments

Even though much of the population in developing countries is involved in agriculture, food security is virtually out of reach. Often the only resort is to purchase a cow, buffalo or sheep to provide a steady supply of fresh milk, a nutritious staple of a daily diet. But how to preserve it safely? Research has found that short pulsed electric fields can be used to kill milk-contaminating bacteria.

Rodents’ Disease-carrying Threat Predicted by Researchers

May 19, 2015 11:04 am | by Seth Augenstein, Digital Reporter | News | Comments

In the 14th century, Europe was devastated by the Black Death, a scourge spread by rodent populations. Now, a group of 21st century researchers are trying to forecast where rats and mice and other critters are most likely to spread viruses, bacteria, fungi and other illnesses communicable to humans.

Study Explains Nature's Reason for Gender

May 19, 2015 7:00 am | by Univ. of East Anglia | News | Comments

Biologists have long puzzled about how evolutionary selection, known for its ruthless requirement for efficiency, allows the existence of males— when in so many species their only contribution to reproduction are spermatozoa. Now, research has found, when males compete and females choose over reproduction, it improves population health and protects against extinction, even in the face of genetic stress from high levels of inbreeding.

Climate, Migration Mean We’ll Be Sweating the Future

May 19, 2015 7:00 am | by Associated Press, Seth Borenstein | News | Comments

The combination of global warming and shifting population means that by mid-century, there will be a huge increase in the number of Americans sweating through days that are extremely hot. People are migrating into areas— especially in the South— where the heat is likely to increase more, according to a study that highlighted the places where the double whammy looks to be the biggest.

Nanosponges Clean Up MRSA Infections

May 18, 2015 3:00 pm | by UC San Diego | News | Comments

Nanoengineers have developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA, an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA— without the use of antibiotics.
