CHAMPAIGN, Ill. — A team of researchers has shown that 8-month-old infants expect objects they identify as animals to have insides. The study appears in the Proceedings of the National Academy of Sciences. University of Illinois professor of psychology Renée Baillargeon, who led the new study with graduate student Peipei Setoh, said that many psychologists have theorized that babies are born with core physical and psychological frameworks that help them navigate the world. For instance, when babies see a self-propelled object, their core physical framework leads them ...

CHAMPAIGN, Ill. — Researchers have transported two endangered freshwater mussel species from Pennsylvania to Illinois in an attempt to re-establish their populations in the western part of the Ohio River Basin. The team of biologists, led by Jeremy Tiemann, of the Illinois Natural History Survey (INHS), traveled to the site of a bridge-replacement project on Pennsylvania's Allegheny River to collect northern riffleshell (Epioblasma rangiana) and clubshell (Pleurobema clava) mussels. The INHS is a division of the Prairie Research Institute at the University of Illinois. The ...

At work on the International Space Station, researchers studying plant and cell growth in space encountered a challenge. Imaging revealed interesting spaceflight-associated root morphologies. They needed to fix the tissues for further study back on Earth, but conventional fixation methods require separate fixatives depending on whether the sample is intended for molecular or morphological study. If the scientists wanted to study how spaceflight affected patterns of gene expression central to morphological patterns of cell growth, they needed a fixation method that would ...

More than one billion people worldwide rely on fish as an important source of animal protein, states the United Nations Food and Agriculture Organization. And while fish provide slightly over 7 per cent of animal protein in North America, in Asia they represent about 23 per cent of consumption. Humans consume low levels of methylmercury by eating fish and seafood. Methylmercury compounds specifically target the central nervous system, and among the many effects of their exposure are visual disturbances, which were previously thought to be solely due to methylmercury-induced ...

The worst impacts of climate change on the world's poorest fishing communities can likely be avoided by careful management of the local environment and investing in the diversification of options for local people, according to the Wildlife Conservation Society and James Cook University. Climate change is already putting pressure on fishers who depend on nature for their livelihoods. In a new study, scientists found large differences in the potential to adapt based on the local mixture of social and environmental characteristics, requiring a variety of management approaches ...

CHICAGO --- A new study shows significant health benefits for uninsured people living under the federal poverty level in the suburbs when they receive access to primary care. Uninsured residents in a suburban collar county of Chicago reported a big improvement in their health status and increased their preventive care and screenings after one year of access to primary care, reports Northwestern Medicine research. The study illustrates the potential benefits of the Affordable Care Act (ACA) implementation and a promising solution to accessible health care for what are ...

BLOOMINGTON, Ind. -- The modern-day tulip tree, state tree of Indiana as well as Kentucky and Tennessee, can trace its lineage back to the time of the dinosaurs, according to newly published research by an Indiana University paleobotanist and a Russian botanist. The tulip tree, Liriodendron tulipfera, has been considered part of the magnolia family. But David Dilcher of Indiana University Bloomington and Mikhail S. Romanov of the N.V. Tsitsin Main Botanical Garden in Moscow show that it is closely related to fossil plant specimens from the Lower Cretaceous period. Their ...

Most of the time, we try to avoid inflicting pain on others — when we do hurt someone, we typically experience guilt, remorse, or other feelings of distress. But for some, cruelty can be pleasurable, even exciting. New research suggests that this kind of everyday sadism is real and more common than we might think. Two studies led by psychological scientist Erin Buckels of the University of British Columbia revealed that people who score high on a measure of sadism seem to derive pleasure from behaviors that hurt others, and are even willing to expend extra effort to make ...

Irritable bowel syndrome patients extensively suffer from chronic visceral hypersensitivity, with involvement of all levels of the brain-gut axis, as well as various neurotransmitters. Chronic visceral hypersensitivity can occur in the periphery, spinal cord and central nervous system, which has been shown to be the main pathophysiological mechanism underlying abdominal pain in patients with irritable bowel syndrome. Acupuncture at Tianshu (ST25) and Shangjuxu (ST37) has been reported to relieve visceral hypersensitivity for irritable bowel syndrome. Xinxin Guo and colleagues ...

The population of northeastern China has a high incidence of ischemic stroke. Previous studies have shown that intracranial large-artery atherosclerosis is one of the main causes of ischemic stroke, and that the mechanisms are related to inflammation and thrombosis of the affected arteries. A recent study by Lianqiu Min and colleagues from Liaoning Medical University observed the effects of atorvastatin treatment in 89 patients from northeastern China with acute ischemic stroke caused by intracranial large-artery atherosclerosis by measuring changes in the levels of markers ...

Astragaloside IV, the main component of the traditional Chinese medicine astragalus membra-naceus, has been shown to inhibit inflammation, oxidation, and apoptosis, and exerts immu-noregulatory effects. Xiaohong Zhang and colleagues from School of Pharmacutical Sciences, Jilin University investigated whether astragaloside IV could promote the repair of injured sciatic nerve. Denervated sciatic nerve of mice was subjected to anastomosis. The mice were intraperitoneally injected with 10, 5, 2.5 mg/kg astragaloside IV per day for 8 consecutive days. The researchers found that ...

Singapore, 11 September 2013 – By binding multiple molecules of a common leukemia drug with nanodiamonds, scientists from the National University of Singapore (NUS) and University of California, Los Angeles (UCLA) managed to boost the delivery of the drug to leukemic cells and retain the drug within the cells to combat the cancer. This novel discovery, reported for the first time, addresses one of the major challenges in the treatment of leukemia where the cancer cells develop ways to pump drugs out of the body before they can do their job, particularly after they are ...

SYDNEY: A UNSW-led team of astronomers has begun to map the location of the most massive and mysterious objects in our galaxy – the giant gas clouds where new stars are born. Using a telescope at Coonabarabran that narrowly escaped devastation in a recent bushfire, the team identifies the galactic clouds of molecular gas - which can be up to 100 light years across - from the carbon monoxide they contain. "On Earth, carbon monoxide is poisonous – a silent killer. But in space, it is the second most abundant molecule and the easiest to see," says Professor Michael Burton, ...

Researchers at The Mount Sinai Medical Center have developed an innovative system to test how a virus interacts with cells in the body — to see, for example, what happens in lung cells when a deadly respiratory virus attacks them. In the journal Cell Host & Microbe, investigators say such a technique will not only speed basic research into viral biology, it will also help scientists improve vaccine production, generate novel antiviral compounds, and advance the development of viruses that attack cancer cells. "We have a powerful system in place today to investigate ...

CORAL GABLES, FL (September 9, 2013) — Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system. The appearance of this "ultrafast machine ecology" is documented in a new study published on September 11 in Nature Scientific Reports. The findings suggest that for time scales less than one second, the financial ...

Rosemont, Ill. – The American Academy of Orthopaedic Surgeons (AAOS) today released a list of specific tests or procedures that are commonly ordered but not always necessary in orthopaedics as part of the Choosing Wisely® campaign, an initiative of the ABIM Foundation. The list identifies five targeted, evidence-based recommendations that can support conversations between patients and physicians about what care is really necessary. The Academy's list identified the following five recommendations: Avoid performing routine post-operative deep vein thrombosis ultrasonography ...

Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much as half of their body fluids in a single day. Two groups of scientists working on fruit flies, mice and cultured human intestinal cells studied cholera toxin, produced by the highly infectious bacterium Vibrio cholerae. They discovered the toxin exerts some of its devastating effects by reducing the delivery of proteins to molecular junctions that ...

Some of the hottest days and coldest nights in parts of Europe have warmed more than four times the global average change since 1950, according to a new paper by researchers from the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science and the University of Warwick, which is published today (11 September 2013) in the journal 'Environmental Research Letters'. The researchers translated observations of weather into observations of climate change using a gridded dataset of observations stretching back to ...
