Scientists are reporting that the insect's long, flexible legs have an optimal length that keeps it afloat. |
Treatment Outcomes Highlight Dangers Of Extensively Drug-resistant Tuberculosis | In a retrospective study of 174 tuberculosis patients, patients with extensively-drug-resistant tuberculosis were almost eight times as likely to die as patients with multi-drug resistant tuberculosis. The study highlights the need for optimal management of multidrug resistant cases to prevent the progression to XDR-TB. |
New Decision Model Seeks To Avert Flu Vaccine Mismatch Of 2007-2008 Season | To avoid producing vaccines that treat the wrong strains during flu season, the FDA should consider deferring some of its selections as well as other changes to the vaccine composition, according to a study by two decision analysts published in a journal of the Institute for Operations Research and the Management Sciences. |
Whom Do We Fear Or Trust? | Princeton psychology researchers have developed a computer program that allows scientists to analyze better than ever before what it is about certain human faces that makes them look either trustworthy or fearsome. In doing so, they have also found that the program allows them to construct computer-generated faces that display the most trustworthy or dominant faces possible. |
Acid Rain Reduces Methane Emissions From Rice Paddies | Acid rain from atmospheric pollution can reduce methane emissions from rice paddies by up to 24 per cent according to new research. This is potentially a beneficial side effect of the high pollution levels China - the world’s largest producer of rice - is often associated with. Methane is 21 times more powerful as a greenhouse gas than carbon dioxide. |
Fossil And Molecular Evidence Reveals The History Of Major Marine Biodiversity Hotspots | Experts have described three major marine biodiversity hotspots in the last 50 million years, from the oldest, peaked in southwest Europe and northwest Africa, to the modern Indo-Australian Archipelago hotspot. The birth, evolution and death of such hotspots are a product of ecological processes operating over geological time scales of millions of years. To what extent is human activity speeding the evolutionary process of the focus with the highest level of biological diversity, the coral reef ecosystems? |
Researchers Unveil Vital Key To Cancer | University of Manchester scientists have uncovered the 3-D structure of Mps1 -- a protein that regulates the number of chromosomes during cell division and thus has an essential role in the prevention of cancer -- which will lead to the design of safer and more effective therapies. |
Entomologists Use 'Love Potion' To Detect Hidden Cerambycid Beetles | Pest cerambycids can cause severe damage to standing trees, logs and lumber. How then might they be promptly detected and their numbers swiftly controlled? The new discovery of inexpensive blends of love potions has helped researchers detect several species of pest cerambycid beetles. |
When Neurons Fire Up: Study Sheds Light On Rhythms Of The Brain | Neuroscientists have modeled the random synchronization of neuron activation. The findings expand scientists' understanding of brain rhythms, both reoccurring and random, and shed light on the decades-old mystery of how the brain learns temporal patterns. |
Child Development: Lack Of Time On Tummy Shown To Hinder Achievement | The American Physical Therapy Association is urging parents and caregivers to ensure that babies get enough "tummy time" throughout the day while they are awake and supervised, in light of a recent survey of therapists who say they've noticed an increase in motor delays in infants who spend too much time on their backs while awake. |
West Nile's Targets Uncovered | Screening the entire human genome, scientists have identified several hundred genes that impact West Nile virus infection. |
Wheezing After Early-life Antibiotics | Children who are given antibiotics in their first three months often wheeze at 15 months of age. However, this wheezing is probably more due to the presence of chest infections than to the use of antibiotics. |
Quantum Computers Are One Step Closer | Complex computer encryption codes could be solved and new drug design developed significantly faster because of new research. The reality of a workable quantum computer is one step closer. Researchers have shown for the first time that it is possible to make these computers in silicon rather than a vacuum, which has been the focus of previous research. |
Humans' Response To Risk Can Be Unnecessarily Dangerous | The traffic light ahead of you is turning yellow. Do you gun the engine and speed through the intersection, trusting that others will wait for their green, or do you slow down and wait your turn? Researchers contend that our ancient instincts don't meet the decision-making needs of a modern world. |
Stretchable Silicon Camera Next Step To Artificial Retina | Digital cameras have transformed the world of photography. Now new technology inspired by the human eye could push the photographic image farther forward by producing improved images with a wider field of view. By combining stretchable optoelectronics and biologically inspired design, scientists have created a remarkable imaging device, with a layout based on the human eye. |
Measuring Cancer Therapy Success With Oxygen | Scientists have identified a way to predict very early in the treatment process the outcome of radiation and chemotherapy for cervical cancer patients -- based on oxygen levels within the tumor. |
Alcohol Consumption Declining, According To Results Of New Study | Overall alcohol use -- particularly consumption of beer -- is declining in the US, according to a new study. Researchers examined 50 years of data and found several changes in alcohol intake but no change in alcohol use disorders. Americans are drinking significantly less beer and more wine, while hard liquor use has remained fairly constant. More people now report that they are nondrinkers. |
Jupiter And Saturn Full Of Liquid Metal Helium | A strange metal brew lies buried deep within giant gaseous planets such as Jupiter and Saturn. A new study demonstrates that metallic helium is less rare than was previously thought, and is produced under the kinds of conditions present at the centers of giant gaseous planets such as Jupiter and Saturn, mixing with metal hydrogen to form a liquid metal alloy. |
Remedial Instruction Rewires Dyslexic Brains, Provides Lasting Results, Study Shows | A new brain imaging study of dyslexic students and other poor readers shows that the brain can rewire itself and overcome reading deficits, if students are given 100 hours of intensive remedial instruction. The study shows that the remedial instruction resulted in a brain activity increase in cortical regions associated with reading, and that neural gains solidified further during the year following instruction. |
Weird Oxygen Bonding Under Pressure Explained | Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor. Now, researchers have found for the first time that under pressure the molecules interact through their outermost electron clouds or "orbitals." |
Stent Grafts: A Better Way To Treat Blunt Trauma Injuries | Endovascular repair -- fixing an injury in a blood vessel from inside that vessel -- is a better option for individuals who receive highly lethal injuries from high-speed collisions or falls (together referred to as blunt trauma) and is shown to save more lives and nearly eliminate paraplegia (the loss of the ability to move and/or feel both legs), a complication of surgical repair for thoracic aortic aneurysms. |
Neurobiologists Discover Individuals Who 'Hear' Movement | Individuals with synesthesia, or cross-activated senses, perceive the world differently from others, with some perceiving numbers or letters as having colors or days of the week as possessing personalities. Now, researchers have discovered a type of synesthesia in which individuals hear sounds when they see things move or flash. The scientists say auditory synesthesia, which had never been identified, may represent an enhanced form of how the brain normally processes visual information. |
How Bacteria Attach To Human Tissues During Infection Process: New Clues | Scientists have helped to reveal more about the way bacteria can attach to human tissues. The researchers studied the way a protein found on the surface of the bacteria Staphylococcus aureus binds to a human protein called fibronectin. Their discovery is an important step in understanding how bacteria attach to the surface of blood vessels during infection. |
Shape, Not Just Size, Impacts Effectiveness Of Emerging Nanomedicine Therapies | In the budding field of nanotechnology, scientists already know that size does matter. But now, researchers have shown that shape matters even more -- a finding that could lead to new and more effective methods for treating cancer and other diseases, from diabetes and multiple sclerosis to arthritis and obesity. |
Metabolic Insight To Illuminate Causes Of Iron Imbalance | New insight into key players in iron metabolism has yielded a novel tool for distinguishing among root causes of iron overload or deficiency in humans, researchers report. While the body needs iron to produce hemoglobin, a substance in red blood cells that enables them to carry oxygen, too much iron can build up and eventually damage organs. |
Context And Personality Key In Understanding Responses To Emotional Facial Expressions | It is well-appreciated that facial expressions play a major role in nonverbal social communication among humans and other primates, because faces provide rapid access to information about the identity and the internal states and intentions of others. New data now suggests that both the social context of a person's facial expression and certain facets of the viewer's personality could affect how our brain interprets the social meaning of someone else's smile or frown. |
Water Is 'Designer Fluid' That Helps Proteins Change Shape | According to new research, old ideas about water behavior are all wet. Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought. |
Why Treatment Isn't Effective For HIV | Researchers have answered a key question as to why antiretroviral therapy isn't effective in restoring immunity in HIV-infected patients. Once a person is infected with the virus, fibrosis, or scarring, occurs in the lymph nodes -- the home of T cells that fight infection. And once fibrosis occurs, T cells can't repopulate the lymph nodes when HIV therapy begins, according to a professor of medicine and principal investigator on the study. |
Switching On First Neutrons At UK's ISIS Second Target Station | The UK's ISIS Second Target Station Project moved a major step closer to completion when the first neutrons were created in the ISIS Second Target Station. ISIS uses neutrons to study materials at the atomic level with a suite of instruments, often described as 'super-microscopes.' By scattering neutrons off sample materials, scientists can visualize the positions and motions of atoms and make discoveries that have the potential to affect almost every aspect of our lives. |
Evaluating Ecosystem Services | Environmental conservation efforts have traditionally focused on protecting individual species or natural resources. Scientists are discovering, however, that preserving the benefits that whole ecosystems provide to people is more economically and environmentally valuable. Ecologists will explore the application of ecosystem services approaches to conservation. |
