What happens to marine life when oxygen is scarce?

Monday July 26th, 2021 08:58:45 PM
In September of 2017, marine biologists were conducting an experiment in Bocas del Toro, off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in hiding, perching on the tops of coral. This observation prompted a collaborative study analyzing what this foggy water layer is caused by, and the impact it has on life at the bottom of the seafloor.

Scientists model 'true prevalence' of COVID-19 throughout pandemic

Monday July 26th, 2021 07:28:55 PM
Scientists have developed a statistical framework that incorporates key COVID-19 data -- such as case counts and deaths due to COVID-19 -- to model the true prevalence of this disease in the United States and individual states. Their approach projects that in the U.S. as many as 60 percent of COVID-19 cases went undetected as of March 7, 2021, the last date for which the dataset they employed is available.

Supernova's 'fizzled' gamma-ray burst

Monday July 26th, 2021 06:48:45 PM
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books -- the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen.

Hubble finds evidence of water vapor at Jupiter's moon Ganymede

Monday July 26th, 2021 05:21:25 PM
Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.

Second COVID-19 mRNA vaccine dose found safe following allergic reactions to first dose

Monday July 26th, 2021 03:39:45 PM

The study looks at a species of softshell turtle, but the results could help to illuminate an important evolutionary process in many species. The research centers on a process known as sex chromosome dosage compensation.

Two types of blood pressure meds prevent heart events equally, but side effects differ

Monday July 26th, 2021 02:21:43 PM
In an analysis of almost 3 million patients taking a single high blood pressure medication for the first time, angiotensin receptor blockers (ARBs) were as good as angiotensin-converting enzyme (ACE) inhibitors at preventing cardiovascular events linked to hypertension, including heart attack, stroke and heart failure. 51 possible side effects and safety concerns were examined: The patients taking ARBs were found to be significantly less likely to develop tissue swelling, cough, pancreas inflammation and bleeding in the digestive tract.

Friday July 23rd, 2021 04:14:56 PM
Researchers have developed a general framework and metadevices for achieving dynamic control of THz wavefronts. Instead of locally controlling the individual meta-atoms in a THz metasurface (e.g., via PIN diode, varactor, etc.), they vary the polarization of a light beam with rotating multilayer cascaded metasurfaces.

Why four-legged animals are better sprinters

Friday July 23rd, 2021 02:53:19 PM
Scientists have studied the characteristics determining the maximum running speed in animals. The model they developed explains why humans cannot keep up with the fastest sprinters in the animal kingdom. Based on these calculations, the giant spider Shelob from 'The Lord of the Rings' would have reached a maximum speed of 60 km/h.

Reverse optogenetic tool developed

Friday July 23rd, 2021 02:53:16 PM
A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers. They used an opsin -- a protein that occurs in the brain and eyes -- from zebrafish and introduced it into the brain of mice. Unlike other optogenetic tools, this opsin is not switched on but rather switched off by light. Experiments also showed that the tool could be suitable for investigating changes in the brain that are responsible for the development of epilepsy.

Investigational magnetic device shrinks glioblastoma in human test

Thursday July 22nd, 2021 08:30:00 PM
Researchers shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy in his own home. The 53-year-old patient died from an unrelated injury about a month into the treatment, but during that short time, 31% of the tumor mass disappeared. The autopsy of his brain confirmed the rapid response to the treatment.

Cattle losing adaptations to environment

Thursday July 22nd, 2021 08:29:57 PM
Researchers have uncovered evidence showing that cattle are losing important environmental adaptations, losses the researchers attribute to a lack of genetic information available to farmers. After examining genetic material stretching back to the 1960s, they identified specific DNA variations associated with adaptations that could one day be used to create DNA tests for cattle -- tests that could tell farmers whether their cattle are suited for one environment or another.
