A research team has addressed the long-standing challenge of creating artificial olfactory sensors with arrays of diverse high-performance gas sensors. Their newly developed biomimetic olfactory chips (BOC) are able to integrate nanotube sensor arrays on nanoporous substrates with up to 10,000 individually addressable gas sensors per chip, a configuration that is similar to how olfaction works for humans and other animals.
Researchers report that mature oligodendrocytes -- the central nervous system cells critical for brain function -- cling to life following a fatal trauma for much, much longer than scientists knew. The findings suggest a new pathway for efforts to reverse or prevent the damage that aging and diseases such as multiple sclerosis cause to these important cells.
There has been a redistribution in the risk of arterial disease in type 1 and 2 diabetes. The risks of heart attack and stroke have decreased significantly, while complications in more peripheral vessels have increased in relative importance, according to new studies.
Researchers have found that a gut microbiome deficient in Clostridium bacteria could influence bile acid synthesis and hamper glucose metabolism
For his contributions to astronomy, the International Astronomical Union has named an asteroid after Prof. Jayant Murthy. Here’s a quiz on other asteroid names
March 20th is celebrated as World Frog Day. Take this quiz to know more about these fascinating amphibians
Sgr A* possesses 4 million times the mass of our sun and is located about 26,000 light-years - the distance light travels in a year, 9.5 trillion km from Earth.
Martin Rees said space travel should only be for those prepared to accept a "very high level of risk", and it should be paid for privately rather than by the taxpayer
The picture scientists are putting together offers a detailed look at the origins of crucial elements around us, like the calcium in our teeth and the iron in our blood
According to the U.S. Coast Guard, just before the collision, the Dali lost all mechanical power, electronics, and the ability to steer the ship
Researchers say the rice variety’s export potential can be maximised by cultivating it in places where its flavour compounds are expressed the most
The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations discovered in 2021 play a crucial role in controlling the Sun's rotational pattern. The long-period oscillations are analogous to the baroclinically unstable waves in Earth's atmosphere that shape the weather. In the Sun, these oscillations carry heat from the slightly hotter poles to the slightly cooler equator.
Researchers have introduced a new, refined method for analyzing brain signals, enhancing our understanding of brain functionality. This research has the potential to improve treatments for neurological conditions such as Parkinson's disease, pain, epilepsy and depression.
Artificial intelligence (AI) may serve as a future tool for neurologists to help locate where in the brain a stroke occurred. In a new study, AI processed text from health histories and neurologic examinations to locate lesions in the brain. The study looked specifically at the large language model called generative pre-trained transformer 4 (GPT-4).
Researchers can use the light naturally thrown off by biological specimens to better study the different states of stem cells in the nervous system, thanks to a tool brightening their chances for studying the way stem cells age.
Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.
New research finds that not all cattle are the same when it comes to grazing, and knowing that could lead to better animal health and range conditions.
Researchers have found that approved drugs that were originally shown to normalize blood vessels surrounding tumors (to improve drug delivery to cancer cells) can enhance the delivery of anti-microbial medications to kill tuberculosis bacteria residing in the lungs.
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.
