The Federal Reserve has revealed that despite interruptions caused by extreme winter storms, the US economy has shown a growth at moderate pace through mid-February. The Fed said that out of the 12 regions, six have reported moderate growth with modest gains seen in most other areas. The Boston district reported that the businesses in its area remained up despite several huge snowstorms.

According to the Fed survey, the consumer spending rose in most of the districts, travel and tourism increased, and manufacturing has shown solid gains with San Francisco region's aerospace companies forecasting a record year.

Research team working on the Anti-Amyloid Treatment in Asymptomatic Alzheimer's Disease (A4) Study have been provided with an extra $8 million so that they can study additional aspects of the disease.

These funds will be helpful to support additional evaluations in a subset of A4 participants. Brain PET scans are the most important ones as they are intended to measure participants' burdens of tau protein deposits.

Researchers have been trying to use oxygen against cancer. A team of researchers have come one step closer in the experiment, which could lead to breakthrough treatment for cancer by boosting the immune sysmte.

As per the novel research, high-dose oxygen would be beneficial in stimulating immune system against cancer. The research, which was carried out on mice, has paved the way for the theory.

Susanna Greer, Director of clinical research and immunology for the American Cancer Society, was of the view that this is a simple approach, which can bring significant improvements and could make cancer therapies better.

According to University of BC scientists, they have figured out why a certain type of fungus is destroying poplar trees. It was found by the researchers that the fungus, Mycosphaerella populorum, makes use of extra genes to produce a toxin.

As per the researchers, this toxin can cause lethal lesions on the leaves, stems and branches of poplar trees. Through genome sequencing, the researchers were able to found the extra genes. The study has been published the Proceedings of the National Academy of Sciences.

As per a recent statement by NASA, researchers at the agency’s Ames Research Center in California were successful in recreating three of the basic chemical building blocks of the genetic material essential for existence and continuance of life on Earth.

The agency informed that the team of researchers was able to reproduce uracil, cytosine, and thymine. These three occur in the genetic information contained in ribonucleic (RNA) and deoxyribonucleic (DNA) acids.

The laboratory where the test was performed had conditions that simulated the extreme environment of space, it said.

Researchers for the experiment placed a sample of ice on a substrate in a chamber at minus 440 degrees Fahrenheit. It was then exposed to high-energy ultraviolet radiation emitted by a hydrogen lamp.

It has been more than 100 years for the establishment of NASA, which was originally formed as the National Advisory Committee for Aeronautics, or NACA, on March 3, 1915. NACA was created after concerns were raised in the US for becoming second in line behind Europe in aviation technology,

With its inception, the field of aeronautics began to make a series of technological advancements. NACA was converted in National Aeronautics and Space Administration, NASA, in 1958 to look into space programs, aeronautics and the advancement of aerospace technology.

Leaders, directors and researchers of NASA were none other than great minds of NACA, including famous space explorers, such as Neil Armstrong, Robert Gilruth, Chris Kraft and many others.
