Letting the Hua Cat Out of the Bag

October 5th, 2008

Good news from 10-2-08 OSU Media Release:

Dr. Rich Carter is at it again! Working with Hua Yang, an OSU postdoctoral research associate, Carter has developed a new and improved “organocatalyst”. Hua Cat is environmentally friendly, inexpensive and very effective chiral compound (chiral compounds are the basis for about 90% of all new drug development, which by the way is soon to be a $5 billion industry). It provides solubility that’s more than 10 times higher than related compounds now being used. Thusly:

Dr. Carter explains, “This is a comparison image of our invention, Hua Cat, versus a competitor. As you can clearly see, the vial on the top is clear and all of Hua Cat is dissolved. In contrast, the vial on the bottom contains one of our competitors, which is completely insoluble in the same solvent. As our catalyst Hua Cat is completely dissolved, it is much more readily able to catalyze the reaction. In contrast, the competitor is not dissolved and unable to catalyze the reaction.”

Environmental Sleuthing

September 30th, 2008

Why is the air hazy today?

Why aren’t fishing conditions as good as they used to be?

And… what is Dioxin, anyway?

Oregon State University is helping the community understand the answers to these questions through their Community Outreach and Education Program. The Environmental Health Sciences (EHS) Center and the Marine and Freshwater Biomedical Sciences (MFBS) Center present Unsolved Mysteries of Human Health: how scientists study toxic chemicals.

This kid-friendly site gives us an inside look at the methods and instruments that experts use to solve environmental mysteries. One scenario revolves around two such instruments – the gas chromatograph and the mass spectrometer, working in conjunction to detect chemicals in the air. Another scenario describes the flow cytometer, a device that measures cells in liquid.

The goals of the website include increasing student interest in the field of environmental health science, increasing the public’s understanding of environmental health science research, and highlighting current research being performed at the EHS and MFBS Centers.

Oldest Gecko Fossil Ever Discovered!

August 28th, 2008

Approximately 100 million years old, that is:

gecko in amber

This is at least 40 million years older than the oldest known gecko fossil.

Scientists from Oregon State University and the Natural History Museum in London have announced the discovery of the oldest known fossil of a gecko, with body parts that are forever preserved in life-like form after 100 million years of being entombed in amber.

Due to the remarkable preservative power of being embalmed in amber, the tiny foot of this ancient lizard still shows the tiny “lamellae,” or sticky toe hairs, that to this day give modern geckos their unusual ability to cling to surfaces or run across a ceiling. Research programs around the world have tried to mimic this bizarre adhesive capability, with limited success.

Vince!

August 20th, 2008

Vince We’d like to introduce you to Dr. Vince Remcho. He’s our new Associate Dean in the College of Science–everyone is so glad he succumbed to the wooing of his colleagues and has taken on this new role.

He’ll continue to stay busy as a Professor of Chemistry and Professor of Materials Science in our Chemistry Department. (He also holds adjunct appointments in Biochemistry & Biophysics and Industrial & Manufacturing Engineering.)

In all of his free time, Vince is an avid bike commuter. Standard apple-tree kind of thing: his kids have not missed A SINGLE day of bike commuting to school in four years. Not one.

We at Breakthroughs are happy, happy about Vince and we hope you will be, too. Stay tuned for more about (and perhaps from, hint, Vince?) in the future.

Here’s a photo of Vince in his lab. We asked him what he’s up to there… we’ll just quote him because it sounds more natural coming from him:

I am holding a “master”, designed and produced by Myra Koesdjojo (a senior Ph.D. candidate in my group), used for replica molding of a microfluidic or “lab-on-a-chip” device. The master is made using silicon wafer fab technology and consists of a polished silicon wafer onto which a photoresist is spin-coated. The photoresist is then patterned using the piece of equipment I am standing in front of, an IMP SF-100 direct write photolithography system. We then use a thermopneumatic press to transfer the features from the master into plastics such as polymethylmethacrylate (PMMA) and polycarbonate (PC), and layer-p to generate complex 3-D fluidic networks. The finished devices are used for multi-step biochemical and environmental analyses and can also be applied to chemical labeling and synthesis operations.

Vince also wanted us to know that the real story in the lab is driven by the students and proudly shared this group photo. Myra Koesdjojo, mentioned above, is third from the left:

OSU Receives Grants to Study Cellulosic Ethanol

August 19th, 2008

The USDA and Department of Energy recently announced plans to award 10 grants totaling more than $10 million to accelerate research in biomass genomics to further the use of cellulosic plant material for bioenergy and biofuels. Scientists at OSU are to receive two of the grants, totaling $2.4 million.

Assistant Professor of Botany, Todd Mockler says:

“Ethanol made from cellulose, instead of a food crops such as corn, is clearly one direction the future of biofuels is headed. These projects will all lay the groundwork for applied studies in this field, and give us the fundamental knowledge we need to make cellulosic ethanol more efficiently and help it become a working reality.”

Lionfish Population Has Scientists Worried

Another article about Beijing air quality

August 15th, 2008

Pollution levels unclear but a key concern, from USA Today.

Simonich has been taking air samples for the last seven days. She hasn’t finished her analysis and doesn’t have exact figures, but her rough estimate is that pollution levels are between two and seven times higher than in a typical larger American city and six times higher than the average during the 1996 Atlanta Olympics, the Oregon State University researcher says.

The Million Dollar Chair

August 13th, 2008

Having found a butterfly net stashed away in his family’s closet, Harold Rice began collecting butterflies in his early childhood and has been collecting ever since. In his 90’s today, he is still out and about the state looking for butterflies.

Harold’s love of traveling and passion for butterflies is amply illustrated by his personal collection, which contains well over 30,000 specimens from all over the world. Nearly half of this has already been delivered to the Oregon State Arthropod Collection, with the remainder expected in future years. The material is carefully identified and beautifully pinned into wooden glass-topped drawers.

The local entomology community is fortunate to count Harold among its leaders. He remains a member of the Oregon Entomological Society, having attended their first meeting in the 1930’s , and is an active participant in the Pacific Northwest Lepidoptersist group – a group that has been meeting each fall in the Willamette Valley for the last 30 years.

In 1994 Harold, with the help of OSAC director Jack Lattin, established the Harold and Leona Rice Professorship Endowment in Systematic Entomology. This Professorship is helping OSU recruit a top-notch leader in the field of Insect Systematics (the formal biological study of insect biodiversity and evolution). Part of the Rice Professor’s position is to serve as the Director for the Oregon State Arthropod Collection. A new Rice Professor will be announced during the 2008/2009 academic year.

In the picture here, Chris Marshall, Curator & Collections manager for the OSAC, has just presented Harold with an Oregon State University chair. Amused, Harold jokingly refers to the chair as his “million dollar chair.”
