Tiny Footprints, Big Discovery: Reptile Tracks Oldest Ever Found in Grand Canyon

Numerous hikers every day pass by the fallen boulder along the Bright Angel Trail in Grand Canyon National Park.

It may otherwise go undetected except for the 28 indentations– sloping footprints left by a little, reptile-like creature about 310 million years earlier– that cover the rock’s extensive surface area.

“It’s the earliest trackway ever discovered in the Grand Canyon in a period of rocks that nobody idea would have trackways in it, and they’re among the earliest reptile tracks in the world,” stated Steve Rowland, UNLV professor of geology who is studying the fossil trackways.

A number of popular tracks in Zion National Park closed indefinitely after storms

ZION NATIONAL FOREST, UT( FOX5) -. Several popular trails were closed in Zion National Park after storms in the area damages treking routes last week.

The routes will remain closed till crew and engineers can repair and re-route them, inning accordance with the release. It was not known for how long repairs will take.

The closed trails, identified to be risky, include:

Angels LandingKayentaUpper Emerald PoolsWest Rim from the Grotto Trailhead to Cabin Springand the back of Lower Emerald Pools Trail

Officials stated the damage was substantial in three areas: Refrigerator Canyon on the West Rim Trail, Kayenta Path and the back of Lower Emerald Pools Trail. Fridge Canyon is an area visitors should go through on their method to or from Angels Landing.

In Fridge Canyon, an area of retaining wall stopped working, triggering an 18 foot space in the trail that is over 5 feet deep. As a result, the West Rim Trail in between Cabin Spring (near wilderness campsite # 1) and the Grotto Trailhead in Zion Canyon is closed. This consists of Zion’s popular Angel’s Landing Trail. Visitors are encouraged to use Observation Point Trail or Covert Canyon Trail as options. The West Rim camping sites are open and accessible from the Lava Point Trailhead.
On Lower Emerald Pools Path, a 20 foot by 10 foot stone that was supporting part of the trail fell, leaving a deep space in the path. 2 big keeping walls underlying and supporting the trail likewise failed. The Lower Emerald Pools waterfall is still visible from the Lower Emerald Pools Trail, however visitors can not stroll behind the waterfall. Riverside Walk or the Pa’ rus Path are suggested as options.
On the Kayenta Trail, numerous large stones fell and totally crushed roughly 50 feet of trail, rendering it unpassable at this time. Upper Emerald Pools Path is likewise closed due to the fact that there is no other way to access the path without treking either Lower Emerald Pools Path or the Kayenta Path which are harmed and closed. Watchman Path is recommended as an option for Upper Emerald Pools Trail and Kayenta Trail.

” While we are examining possible temporary re-routes to open tracks, cliffs and high surface limitation those opportunities,” stated Superintendent Jeff Bradybaugh. “Comprehensive repair will be required prior to some routes can be opened. Offered the engineering and comprehensive repairs needed, it is too soon to estimate when each closed path might once again be open to visitor use.”

Revolutionary Gene-editing Method to Stop AIDS Virus in Its Tracks

Scientists with the Nevada Institute of Personalized Medication at UNLV have crafted a brand-new protein that they believe has actually positioned science much closer to an HIV treatment.

A patent application has actually been filed and testing is underway on the protein– called HT-TALENs (short for HIV-targeted transcription activator-like effector nucleases)– which uses a recently established gene-editing technique to rid the body’s cells of the immunodeficiency virus before it has a possibility to increase and potentially turn into AIDS. Right here’s how it works:

Humans contaminated with HIV have 1 million to 10 million cells harboring copies of HIV DNA. When HIV infects somebody, the virus inserts itself into DNA cells and becomes part of those cells’ long-term plan.

“Existing drugs slow the virus from being produced, but they do not free the body of the HIV DNA,” said NIPM executive director and UNLV professor Marty Schiller. “You’ve got to do away with or damage the hazardous DNA to truly avoid the cells from developing the virus.”

By modifying a frequently made use of plant protein, Schiller’s lab crafted the brand-new HT-TALENs variation. Presented into the body through a common cold virus injection, the protein sticks to the specific portions of DNA packed with HIV and serves as a pair of scissors that cuts or damages it without touching any of the non-infected DNA around it. When the cell repair services itself, the new copy will not include functional HIV.

“This is a way we’re getting at the source of AIDS– not pursuing a downstream event, but going after the actual DNA copy– and ideally stopping virus duplication in its tracks,” Schiller said. “We think it has the prospective to be a cure.”

So far, the scientists have just produced results in petri dishes. They are waiting for patent approval and are getting ready to begin on the next phase of testing this winter season through a partnership with Brigham Young University. If that’s successful, the scientists will proceed to human trials.

Timespan for market usage? Schiller dislikes to speculate, however if all goes well the best-case scenario is seven years.

“It’s going to take a number of years to establish, but I’m quite sure this method ought to work and our objective is to blaze a trail,” he stated.

The protein treatment’s success would be a benefit mentally and financially for patients going through existing HIV drug programs, which can top $15,000 a year.

Human tests would combine the brand-new gene-editing protein therapy with existing treatments. The protein may also be useful in curing other health problems like bird flu.

The method is revolutionary, Schiller stated, thinking about that genes– now extensively utilized for prenatal screening and drug development– seemed a simple dream when referenced in the 1993 movie Jurassic Park.

This task– among about 8 Schiller’s lab is presently dealing with– started about three years back after a weekly meeting of Schiller’s team focused on present research study documents. Schiller understood that the TALEN protein, derived from a wheat pathogen already extensively utilized in the agriculture industry to genetically customize plants, described in one paper may be perfect after a couple of tweaks for use in HIV therapy.

The conclusions were published in the Might problem of the peer-reviewed journal PLoS ONE.

Scientists included students with post-doctoral, graduate, and undergraduate status, as well as some support by a local high school junior. Schiller said co-authorship in a significant publication, specifically on a job of this magnitude, is a major coup for young researchers. In fact, co-lead author Christy Strong, a former post-doctoral student, has actually given that become a UNLV professor. The job motivated the other lead author, undergraduate Horacio Guerra, to switch career paths. He changed majors from a pre-med track to focus on clinical research study. He finished in the spring from UNLV with a bachelor’s degree in biology and is now in the graduate program at University of California, San Diego.
