Revolutionary biomimetic olfactory chips to enable advanced gas sensing and odor detection

Science Daily - 28/03/2024
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.

Reverse effects of trauma? Older brain cells linger unexpectedly before their death

Science Daily - 28/03/2024
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.

Clear shift in arterial diseases in diabetes

Science Daily - 28/03/2024
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.

Twisted magnetic field observed around Milky Way's central black hole

The Hindu:Science - 28/03/2024
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.

Send robots into space rather than people, says Britain's Astronomer Royal

The Hindu:Science - 28/03/2024
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

Long-period oscillations control the Sun's differential rotation

Science Daily - 28/03/2024
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 introduce enhanced brain signal analysis technique

Science Daily - 28/03/2024
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.

Could AI play a role in locating damage to the brain after stroke?

Science Daily - 28/03/2024
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).

New tool provides researchers with improved understanding of stem cell aging in the brain

Science Daily - 28/03/2024
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.

Artificial reef designed by MIT engineers could protect marine life, reduce storm damage

Science Daily - 28/03/2024
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.

Understanding cattle grazing personalities may foster sustainable rangelands

Science Daily - 28/03/2024
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.

A combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis

Science Daily - 28/03/2024
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.

Astronomers conduct first search for forming planets with new space telescope

Science Daily - 28/03/2024
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.

Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior

Science Daily - 28/03/2024
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.
