Drug-resistant bugs discovered in animal hospital prompts health warning

Posted by in categories: biotech/medical, health

Pets in a British animal hospital have been found to be harbouring potentially lethal drug-resistant bugs that could be transferred to owners.

Tests by Public Health England (PHE) revealed three cats a dog were colonised by bacteria able to fend off Linezolid, a “last-resort” antibiotic used to treat superbugs such as MRSA (methicillin-resistant Staphylococcus aureus).

No staff or owners are known to have been taken ill as a result, however the agency last night warned veterinary surgeries to enforce proper cleaning practices after this first discovery of its kind.

Go Subterranean With This DARPA Challenge

Posted by in category: robotics/AI

Whether it comes to rescuing people from a cave system or the underground maze of sewers, tunnels and the like that exist underneath any major city, having accurate maps of the area is always crucial to know what the optimal routes are, and what the expected dangers are. The same is true for combat situations, where such maps can mean the difference between the failure or success of a mission. This is why DARPA last year started the Subterranean Challenge, or ‘SubT’ for short.

This challenge seeks new approaches to map, navigate, and search underground environments during time-sensitive combat operations or disaster response scenarios, which would allow for these maps to be created on-demand, in the shortest amount of time possible. Multidisciplinary teams from the world are invited to create autonomous systems that can map such subsurface networks no matter the circumstances.

DNA reveals origin of Stonehenge builders

Posted by in category: biotech/medical

The ancestors of the people who built Stonehenge travelled west across the Mediterranean before reaching Britain, a study has shown.

Researchers in London compared DNA extracted from Neolithic human remains found in Britain with that of people alive at the same time in Europe.

The Neolithic inhabitants appear to have travelled from Anatolia (modern Turkey) to Iberia before winding their way north.

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.

The Simulation Hypothesis: Are We in a Video Game?

Posted by in category: entertainment

A more boisterous scientific and philosophical discourse around the Simulation Theory has been picking up steam ever since The Matrix and The 13th Floor (now classics) came out in 1999.
