Computer imaging assists with facial reconstructive surgery

...xity angle increased after surgery. These changes brought the patients closer to the normal range for these measurements and angles. “Surgery for facial disharmony requires artistic judgment and objective evaluation,?the authors conclude. “For surgeons who use computer imaging software, analysis of prof...

Cancer researchers add spice to research against rare neuromuscular disease

...ould, producing more VEGF. Ultimately, the work brought about healthier mice whose symptoms were much improved. Chang's team also found that the amount of abnormal clumps in the neurons and spinal cords of the mice was slashed by half, and that VEGF activity in the neurons went up more than four times in ...

Some caterpillers just don't want to grow up

...ct on the ecology of Maculinea butterflies has now brought together the CEH team with theoreticians from the universities of Würzburg and Montpellier to investigate this problem. Together they have compiled various potential adaptive explanations for the evolution of such strategies into a general and quanti...

Map predicting spread of avian flu

...ding that in these regions an epidemic can only be brought to an end by massive culling of susceptible farms. For avian influenza, the analyses show that there are two poultry-dense areas in The Netherlands where epidemic spread is possible, one in the central region and one in the south, close to the Germa...

Bats prey on nocturnally migrating songbirds

...eed exclusively on invertebrates! This finding brought about a heated controversy among bat scientists. Some claimed that eating feathers was no proof of preying upon birds: they suggested that giant noctules could simply, and accidentally, ingest feathers hovering in the air, which are particularly nume...

Researchers create artificial enzyme that mimics the body's internal engine

...nd it's been broadly ignored." Each electron is brought to the enzyme one at a time, Collman said: "It's like a bucket brigade in a Western movie." But the electrons are consumed too fast to study individually, he noted. Therefore, the researchers had to invent a technique that supplied electrons to their...

Scientists discover new life forms in the Arctic Ocean

...uted throughout northern seas. They have yet to be brought into culture, but can be seen using advanced microscopy techniques. "It's a very exciting discovery," comments Dr. Lovejoy. "The ocean covers 70% of planet earth and we are only now coming to appreciate its rich and complex biodiversity." The ot...

New protein inhibitor impedes growth of cancerous cells

...mors. The authors report that BI 2536 has now been brought into use in clinical studies of patients with locally advanced or metastatic cancers in order to address the therapeutic potential of the compound. In the companion paper, Lenart et al. use BI 2536 as a tool to probe the functions of Plk1 in norma...

Navigable nanotransport

...acid on the capsules docks into these sites and is brought into the interior of the cell. Here, the contents of the capsule, such as an antitumor drug or contrast agent, can be released to selectively attack the tumor or to make an unambiguous diagnosis. ...

Natural antibiotics yield secrets to atom-level imaging technique

...lished a number of papers in leading journals, and brought out a book on NMR Spectroscopy of Biological Solids. Ramamoorthy says that this area of research will grow considerably at U-M from implementing plans to set up a high magnetic field solid-state NMR spectrometer facility and an NIH-funded program. ...

Improved predictions of warming-induced extinctions sought

...roughly considered, and that better data should be brought to bear on the problem, especially information from the fossil record of Quaternary ice ages. The authors acknowledge, however, that they do not fully understand why so many species persisted during these ice ages, and caution that some genetic resea...

Rare soft-shell turtle, nesting ground found in Cambodia

...rs also found a nesting ground for the species and brought back eggs that have since hatched. The hatchlings were released into the wild on May 8, together with another adult turtle and additional hatchlings captured by fishermen and handed over to the conservation team. Last observed by scientists in the...

Hexavalent chromium in drinking water causes cancer in lab animals

...ssues and organs." Hexavalent chromium has been brought to the public’s attention in many ways, most notably in the movie "Erin Brockovich." Eleven members from the California Congressional Delegation sent a letter to the NTP Director requesting the NTP conduct the studies. Nominations for studying this ...

The quest for an effective HIV vaccine presents new possibilities, challenges

...proved understanding of how HIV causes disease has brought increased attention to the role that T cells could play in an HIV vaccine by spurring cellular immunity. Numerous animal and human studies have confirmed how important cellular immunity is in the early and later stages of HIV infection, even though t...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...d meters, microphones, and reverberation equations brought about a new level of clarity and similarity in the acoustical environments of disparate locations from Boston concert halls to New York skyscrapers and Hollywood sound stages. Princeton's Emily Thompson ( emilyt@princeton.edu ), a technology histori...

Healthy coral reefs hit hard by warmer temperatures

...diseases among susceptible marine species has been brought to an end," said Don Rice, director of the National Science Foundation (NSF) Chemical Oceanography Program, which funded the research through the joint NSF-National Institutes of Health Ecology of Infectious Diseases Program. For 6 years, the int...

Alien plants attack using 'resource conservation' as weapon, researchers say

...xotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and reducing biodiversity. Invaders thrive best in regions where there is an abundance of materials for growth, such as water, nutrients and light. Biologists have...

'Insulator' helps silence genes in dormant herpes virus

...e suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1. After the initial infection, the virus usually remains in the body, hiding out in nearby nerve cells where the victim's immune defenses cannot reach it, causing no symptoms at all. In order to e...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...chers were surprised to find that the therapy also brought about a nearly 35 percent reduction in permanent structural to joints caused by round and after round of osteoarthritic inflammation. To date, treatment of arthritis is dominated by drug treatments like non-steroidal, anti-inflammatory drugs, COX-...

Antarctic icebergs -- Hotspots of ocean life

... by NASA. At the same time, the wealth of data brought new challenges in how to manage this avalanche of information. “The whole is definitely greater than the sum of the parts, and to answer questions across the different areas from ecology to chemistry and climate, scientists need access to all the dat...
