90 New Cases of Measles Reported in U.S. as Outbreak Continues Record Pace

Posted by in categories: biotech/medical, health

The number of new measles cases in the United States rose again this month, the Centers for Disease Control and Prevention said on Monday, bringing the total number to 555 in 2019. This year’s outbreak is on course to be the worst since the country eliminated measles as an endemic disease in 2000.

Health authorities reported 90 additional cases as of April 11, with outbreaks in New York, Washington, California, New Jersey and Michigan, up from 78 the week before. Those cases were largely linked to travelers returning from countries seeing outbreaks of their own, including Israel, Ukraine and the Philippines.

The disease then spread through populations in which large numbers of people are unvaccinated, the C.D.C. said.

African research projects are failing because funding agencies can’t match donor money

Posted by in category: economics

Although African countries appreciate research grants from donor countries, they often chafe at the condition that they bring in their own money in order to be eligible. Some research projects fall by the wayside because African granting agencies simply have no way to provide their share of the money, sometimes called counterfunding, the heads of 15 national science councils in Africa said at a meeting held here on 4 and 5 April.

“Counterfunding,” desired by donor countries, can be 50% of a project’s cost.

Paul Greengard, 93, Nobel Prize-Winning Neuroscientist, Is Dead

Posted by in categories: biotech/medical, neuroscience

Dr. Greengard’s research described how cells react to dopamine, an important chemical messenger in the brain. His work provided the underlying science for many antipsychotic drugs, which modulate the strength of chemical signals in the brain.

“Our work shows the details of how dopamine produces these effects — in other words, what’s wrong in these diseases and what can be done to correct them,” Dr. Greengard said.

Gravitational echo phenomenon will become a key to the new physics, physicist says

Posted by in categories: cosmology, mathematics, neuroscience, physics

Gravitational echoes may be caused by the collision of two black holes, and may indicate that these objects have completely new physical properties. This conclusion was made by RUDN physicists after a series of mathematical calculations. The scientists state that if the existence of the echo phenomenon is confirmed, astrophysicists would have to reconsider their view of compact space objects. The results of the study were published in Physical Review D.

According to the theory of general relativity (GR), any massive object distorts space-time. A similar effect is observed when a heavy metal ball is placed on stretched elastic fabric. The heavier is the ball, the deeper is the depression in the fabric. Similarly, the higher the mass of an object, the more it distorts space-time. Black holes are among the heaviest objects in the universe, and therefore distort space-time the most. When two black holes collide, gravitational waves spread out from the site of collision. They can be compared to rings on the water, or sound waves, but there is one important peculiar feature. Gravitational waves do not propagate spatially—they are themselves the oscillations of space-time.

Gravitational waves from the collision of two black holes decay with time, but on their final stage, they can cause the so-called echo—additional wave scattering. It can be compared to regular acoustic echo. The existence of such gravitational echo has not been confirmed yet, and there are different opinions about its possible source. A RUDN physicist, together with colleagues from the Czech Republic and Russia, assumed that if the existence of gravitational echo is experimentally confirmed, it would be the beginning of the new physics adding to GR.

Astronomers take first, high-resolution look at huge star-forming region of Milky Way

Posted by in categories: particle physics, space

Astronomers from the United States and South Korea have made the first high-resolution, radio telescope observations of the molecular clouds within a massive star-forming region of the outer Milky Way.

“This region is behind a nearby cloud of dust and gas,” said Charles Kerton, an associate professor of physics and astronomy at Iowa State University and a member of the study team. “The cloud blocks the light and so we have to use infrared or radio observations to study it.”

The Milky Way region is called CTB 102. It’s about 14,000 light years from Earth. It’s classified as an HII region, meaning it contains clouds of ionized—charged—hydrogen atoms. And, because of its distance from Earth and the dust and gas in between, it has been difficult to study.

DIY gravitational waves with ‘BlackHoles@Home’

Posted by in categories: computing, cosmology, physics

Researchers hoping to better interpret data from the detection of gravitational waves generated by the collision of binary black holes are turning to the public for help.

West Virginia University assistant professor Zachariah Etienne is leading what will soon become a global volunteer computing effort. The public will be invited to lend their own computers to help the unlock the secrets contained in observed when smash together.

LIGO’s first detection of gravitational waves from colliding black holes in 2015 opened a new window on the universe, enabling scientists to observe cosmic events spanning billions of years and to better understand the makeup of the Universe. For many scientists, the discovery also fueled expansion of efforts to more thoroughly test the theories that help explain how the universe works—with a particular focus on inferring as much information as possible about the black holes prior to their .
