Special Announcement

Potential J-1 Visa Issue

Fermilab employees and users who hold J-1 or J-2 visas sponsored by Fermilab should be aware of a potential visa issue. The US Department of State has informed Universities Research Association, Inc. (URA) that after December 31, 2006 when Fermi Research Alliance (FRA) takes over management of Fermilab, URA will no longer be authorized to sponsor J visas. However, the State Department has not yet authorized FRA to continue this sponsorship. It is expected that FRA authorization will occur, but there is the possibility of a gap between the end of URA visa sponsorship and the start of FRA sponsorship.

During this time, J-1 and J-2 visa holders traveling outside the United States need to be aware of the possibility that their visas may not be recognized by immigration authorities when they re-enter the United States after December 31, 2006. Fermilab has notified current J-1 visa holders of this potential issue and can provide them with documentation to attempt to address this problem if it arises. This issue does not affect the holders of other visa types. More information will be provided when it becomes available. Meanwhile, those with questions should contact Borys Jurkiw (x4363 or borys@fnal.gov), or Melissa Clayton (x 3933 or mclayton@fnal.gov).

Special Announcement

New Employment Website

With enormous help from computing expert Jean Reising, the Employment department has revamped the Jobs at Fermilab website to include Employer of Choice awards, employee profiles, and a focus on diversity initiatives. Excerpts are also included from the "Why Work at Fermilab?" online employee survey. Thanks to all who provided comments!

We are also looking to periodically update our employee profiles on the homepage. Please e-mail your nominations for employees who exemplify what it means to work at Fermilab to hsidman@fnal.gov.

We encourage you to view the updated website and provide feedback on the content and ease of use.

Aurora over Aurora?

Dear FT:

I took this photo at about 8 p.m. Thursday night from the E sector of the Main Ring. It was very beautiful--the most brilliant display we saw occurred while I was setting up the camera (of course).

The northern lights are a result from solar activity, and as beautiful as the Aurora is, it is just as damaging to worldwide HF (short wave) communications that rely on the atmosphere to bounce the signals around the world.

Also, the same light can be seen in a particle accelerator. For an example, take a look at this old photograph of the LBL 60-inch cyclotron beam being unleashed into the air.

Alternative theory of gravity explains large structure formation -- without dark matter

In the standard theory of gravity-general relativity-dark matter plays a vital role, explaining many observations that the standard theory cannot explain by itself. But for 70 years, cosmologists have never observed dark matter, and the lack of direct observation has created skepticism about what is really out there.

Lately, some scientists have turned the question around, from "is dark matter correct?" to "is our standard theory of gravity correct?" Most recently, Fermilab scientists Scott Dodelson and former Brinson Fellow Michele Liguori demonstrated one of the first pieces of theoretical evidence that an alternative theory of gravity can explain the large scale structure of the universe.

"To definitively claim that dark matter is the answer, we need to find it," Dodelson explained to PhysOrg.com. "We can do this in one of three ways: produce it in the lab (which might happen at Fermilab, the soon-to-start LHC, or ultimately the International Linear Collider), see a pair of dark matter particles annihilate and produce high energy photons (there are about a half dozen experiments designed to look for this), or see a dark matter particle bump a nucleus in a large underground detector (again, about 10 experiments are looking for this). Until one or more of these things happen, skeptics are still allowed. . After they happen, skeptics will become crackpots."

Safety Tip of the Week

CO: New monitor law

Carbon monoxide (CO) detectors range in price from about $20 to $60. Different models plug into the wall, are connected to the building's power line or run on batteries.

Illinois has a new CO detector law that goes into effect on January 1, 2007. All buildings that use fossil fuel and have sleeping rooms or an attached garage must have an approved, operating CO detector installed within 15 feet of any sleeping area.

CO is produced by the incomplete combustion of fossil fuels such as natural gas, gasoline or wood. Typical sources include heating equipment, cooking apparatus and internal combustion engines. CO is odorless, tasteless and invisible. Symptoms increase with concentration and time. Overexposure is often mistaken as seasonal illness since symptoms include dizziness, nausea, headache, coughing, irregular heartbeat, pale skin, and red lips and ear tips. According to the National Safety Council, 200-300 people die each year in the United States from CO poisoning, while thousands more are sickened. Many victims are overcome in their sleep.

The Illinois State Fire Marshal plans to enforce the new law through anecdotal observations. If a local fire department is called to a home, firefighters will check to see if there are working CO detectors. If not, the homeowner will be given a warning. Firefighters will come back later and issue a citation if the owner still hasn't complied. Violators are subject to a Class B misdemeanor, punishable by up to six months in jail and a $1,500 fine.
