The Trump administration’s new construction rules could put tens of thousands of workers out of work

WASHINGTON — The Trump administration has proposed new rules for construction, with the aim of reducing the number of jobs lost when construction equipment breaks down.

The proposed rules, the first major policy document from the administration since taking office, call for companies to notify workers of potential equipment failures within 45 days, but they do not require them to pay for repairs.

In addition, contractors must submit quarterly reports detailing their progress on repairs and provide information on how workers can be notified if equipment fails.

Trump also is rolling back a rule that required all construction workers to wear masks when working on sensitive sites.

On Wednesday, the White House released the proposed regulations, which will be available on the Federal Register later this month.

But a senior administration official said the administration’s proposed rules do not mean that workers will be allowed to go to work without masks, but instead that workers would need to get their workers masks and report them to the National Occupational Safety and Health Administration, which oversees safety at construction sites.

In addition to mandating workers wear protective gear, the regulations also include a provision to provide employers with an opportunity to waive the mandatory mask requirement for workers who are sick, injured or on leave, if they are unable to wear the masks.

A similar provision has been in place since the George W. Bush administration, when President Bush ordered that all construction employees wear face masks.

A new way to treat arthritis with a compound made from human cells

Synthetic cells, which mimic the structure of the human body, are now the most widely used treatment for a variety of conditions, including osteoarthritis, multiple sclerosis, and osteoporosis.

But they have a lot of potential drawbacks.

A few years ago, for example, researchers in the U.K. discovered that they didn’t produce enough biofuel to make their artificial skin cells.

Now, a team led by Oxford University researchers is creating the first synthetic skin cell that could potentially make up for this.

They have now published their findings in Nature Nanotechnology.

The team’s synthetic skin cells, made from two types of human cell, have an incredible amount of potential to make artificial skin tissue for various diseases.

For example, the team has already found that it is possible to make synthetic skin tissue from a human fibroblast, which is a stem cell.

And it has shown that synthetic skin can be grown in vitro, which makes it possible to create a functional artificial skin.

However, the synthetic skin is not perfect.

The synthetic cells do not contain the structural information that gives them their properties.

And the cells have not been shown to work in the body.

But the team hopes that the new synthetic skin will be a good step forward in this field, and they plan to test their synthetic skin in the human tissue, tissue culture, and animal models.

A study led by University of California, San Francisco, researchers also published in Nature Methods on March 7 shows that a synthetic skin was able to produce collagen from human keratin.

The researchers also found that the synthetic cells were more efficient at binding to and maintaining connective tissue in mice than the cells made from natural keratin cells.

So the researchers hope that their synthetic cells can be useful for treating diseases that affect connective tissues in people and animals.

The new synthetic cells could also be useful in other fields.

For instance, they could be used to create skin that has properties similar to collagen.

The artificial skin could also help scientists study diseases such as diabetes.

“Our hope is that we can combine the synthetic form of the skin with the natural form of keratin,” said first author Dr. Toni Hoffmann.

“We think we have a new way of looking at the process of creating artificial skin.”

The research was funded by the Wellcome Trust.
