Heavens are dimmed for Chandra space telescope
The $2 billion Chandra spacecraft is losing its sight. A mysterious build-up of grease on one of its camera filters is partially obscuring astronomical objects of study. Astrophysicists say the contamination is causing uncertainty in data, but engineers are hoping that heating up the instrument could boil away the grease. (2003-11-05)

An engineered surface unsticks sticky water droplets
The leaves of the lotus flower and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.

Topical use of arthritis drug provides relief for dry eye disease
An estimated nine million people in the United State alone suffer from significant DED. In a new study, researchers from the Massachusetts Eye and Ear show that topical anakinra (Kineret; Amgen Inc.), a recombinant version of human IL-1Ra approved for treatment of rheumatoid arthritis, significantly reduced dry eye symptoms.

New treatment could reduce chronic lung disease in premature babies
A less traumatic way of delivering surfactant, a lung lubricant that premature babies need to help them breathe, could reduce the incidence of respiratory problems they'll have later, Medical College of Georgia physicians say. (2008-04-29)

Uncovering unique properties in a 2-dimensional crystal
When the dry lubricant molybdenum disulfide is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties. The charged quasi-particles offer potential use in new solar cells and other electronic devices that are controlled by light or designed to control light, to study what physicists call (2012-12-03)

Scripps scientists discover 'lubricant' for Earth's tectonic plates
Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth's mantle that may be acting as a lubricant for the sliding motions of the planet's massive tectonic plates. The discovery may carry far-reaching implications, from solving basic geological functions of the planet to a better understanding of volcanism and earthquakes. (2013-03-20)

Indiana U. at APHA: Studies about why men and women use lubricants during sex
Personal lubricants have long been recommended to women to improve the comfort of intercourse and to reduce the risk of vaginal tearing, which can increase risks for STIs and HIV. Public health professionals also recommend the addition of lubricant to condoms during sexual activity. Despite this routine advice, strikingly little is known about situations in which lubricants are used or whether there are any associated vaginal symptoms. These studies provide insight into lubricant use. (2009-11-09)

Taking Truvada 'as needed' can prevent HIV-transmission amongst people at high-risk
In a study into the prevention of HIV transmission, people who took the antiretroviral drug Truvada were 86 percent less likely to contract the disease than those who took a placebo, report the researchers who led the study. (2015-12-01)

First-ever study: lack of critical lubricant causes wear in joints
For the first time, researchers have linked increased friction with early wear in the joints of animals. Work led by Brown University physician and engineer Gregory Jay, MD, shows mice that do not produce the protein lubricin begin to show wear in their joints less than two weeks after birth. This finding not only points up the protective power of lubricin but also suggests that it could be used to prevent joint wear after an injury. (2007-11-06)

A new species of yellow slug moth from China
A new species of the slug moth genus Monema has been described from China. The name refers to the peculiar caterpillars resembling slugs in many of their characteristics. The recent study of the representatives of the Monema genus in China, published in the open access journal Zookeys, records four species in total and a subspecies present in the country.

Computer hard drives perform better, last longer with novel polyester lubricant
A newly developed polymer could help pave the way to faster and longer lasting computers. The polymer, which serves as a much improved lubricant coating for computers' hard disk drives, will be described for the first time at the national meeting of the American Chemical Society in Philadelphia, Aug. 22-26. The research was done at the University of Illinois at Urbana-Champaign. (2004-08-25)

Greenland ice sheet flow driven by short-term weather extremes, not gradual warming: UBC research
Sudden changes in the volume of meltwater contribute more to the acceleration -- and eventual loss -- of the Greenland ice sheet than the gradual increase of temperature, according to a University of British Columbia study. (2010-12-08)

Breast cancer survivors who experience pain during intercourse may benefit from lidocaine
Scientists at Oregon Health & Science University report that breast cancer survivors who experience pain during sexual intercourse, a common side effect of breast cancer treatment, may achieve comfort when liquid lidocaine is applied strategically to prevent pain. Their research was published online today in the Journal of Clinical Oncology. (2015-07-27)

Joint lubricating fluid plays key role in osteoarthritic pain, study finds

Argonne receives cost-shared DOE grants to improve light-vehicle fuel efficiency
Two Argonne-based research-and-development projects have been selected to receive grants from the US Department of Energy as part of an effort to improve the fuel efficiency of light-duty vehicle engines while promoting collaboration between researchers in government labs, universities and industry. (2007-08-30)

Simulations lead to design of near-frictionless material
Argonne scientists used the Mira supercomputer to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. ALCF researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code. (2015-07-21)

NIH researchers uncover clues related to metal-on-metal hip implants
A new study, bringing together an interdisciplinary team of physicians and engineers from the United States and Germany, made a surprising finding about implants used in hip replacement surgery: Graphite carbon is a key element in the lubricating layer that forms on metal-on-metal hip implants. The lubricant has more in common with the lubrication of a combustion engine than that of a natural joint. The study was funded by the National Institutes of Health. (2011-12-22)

Self-healing surfaces
The engineers' dream of self-healing surfaces has taken another step towards becoming reality -- researchers have produced a electroplated layer that contains tiny nanometer-sized capsules. If the layer is damaged, the capsules release fluid and repair the scratch. (2009-08-03)

Keeping an eye on component cleanliness
There are exceedingly strict cleanliness guidelines for components in sectors such as the automobile industry. And yet monitoring of the process for parts purification has been inadequate to date. Fraunhofer researchers have developed a sensor-based measurement system that is integrated directly in the cleaning system, where it registers and analyzes particles caught up in the cleansing fluid. The researchers are presenting their now-marketable innovation at this year's parts2clean. (2013-10-21)
