The Brain Can Reveal Drinking Status Even After Death

The Brain Can Reveal Drinking Status Even After Death

Scientists who use postmortem brain tissue to study alcohol’s effects on brain structure and function will find this research interesting. Phosphatidylethanol (PEth) is an alcohol metabolite and its concentration in whole blood samples is a biomarker of drinking habits. For this study, scientists examined PEth levels in postmortem brains of individuals known to have had alcohol use disorders (AUDs).

Researchers divided 30 postmortem brains into three groups: 10 with AUDs that had positive serum alcohol levels present at the time of autopsy; 10 with AUDs that did not show positive serum alcohol levels at the time of autopsy; and 10 normal brains. PEth levels were measured in the cerebellum and orbital frontal cortex (OFC) regions.

Results showed that PEth was present in the cerebellum and OFC of all brains in all three groups of subjects, including the controls. The AUD group with detectable serum alcohol levels at the time of autopsy had much higher levels of PEth in both brain areas than either the control group or the AUD group whose subjects did not have detectable serum ethanol at autopsy. Thus, the ability to measure PEth levels in postmortem human brains can be helpful in classifying drinking status in individuals with AUDs at the time of death.

One Of The Most Dangerous Pictures Ever Taken - Elephant’s Foot, Chernobyl. This Is A Photo Of A Now
One Of The Most Dangerous Pictures Ever Taken - Elephant’s Foot, Chernobyl. This Is A Photo Of A Now

One of the most dangerous pictures ever taken - Elephant’s Foot, Chernobyl. This is a photo of a now dead man next the ‘Elephant’ Foot’ at the Chernobyl power plant. 

The image distortions in the photo are created by intense level of radiation almost beyond comprehension. There is no way the person in this photo and the person photographing him could have survived for any more that a few years after being there, even if they quickly ran in, took the photos and ran out again. This photo would be impossible to take today as the rates of radioactive decay are even more extreme now due to a failed military experiment to bomb the reactor core with neuron absorbers.  The foot is made up of a small percentage of uranium with the bulk mostly melted sand, concrete and other materials which the molten corium turns into a kind of lava flow. In recent years, it has destroyed a robot which tried to approach it, and the last photos were taken via a mirror mounted to a pole held at the other end of the corridor for a few seconds. It is almost certainly the most dangerous and unstable creation made by humans.  These are the effects of exposure: 30 seconds of exposure - dizziness and fatigue a week later 2 minutes of exposure - cells begin to hemorrhage (ruptured blood vessels) 4 minutes - vomiting, diarrhea, and fever  300 seconds - two days to live

FDA bans antibacterial soaps; “No scientific evidence” they’re safe, effective
Ban applies to soaps with any of 19 chemicals, including triclosan.

As Ars has reported previously, scientists have found that triclosan and other antimicrobial soaps have little benefit to consumers and may actually pose risks. These include bolstering antibiotic resistant microbes, giving opportunistic pathogens a leg up, and disrupting microbiomes. In its final ruling, issued Friday, the FDA seemed to agree. “Consumers may think antibacterial washes are more effective at preventing the spread of germs, but we have no scientific evidence that they are any better than plain soap and water,” Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research (CDER), said in a statement. “In fact, some data suggests that antibacterial ingredients may do more harm than good over the long-term.”

[…]

The ruling does not affect alcohol-based hand sanitizers or wipes, which the agency is reviewing separately. It also does not affect antiseptic products used in healthcare settings.

Physicists Detect Gravitational Waves, Proving Einstein Right

Physicists Detect Gravitational Waves, Proving Einstein Right

On Thursday (Feb. 11, 2016) at 10:30 a.m. ET, the National Science Foundation will gather scientists from Caltech, MIT and the LIGO Scientific Collaboration in Washington D.C. to update the scientific community on the efforts being made by the Laser Interferometer Gravitational-wave Observatory (LIGO) to detect gravitational waves.

But why is this exciting? And what the heck are “gravitational waves”?
