Brown dwarf: A star-planet hybrid was accidentally discovered thanks to a gas shift

Posted by in category: cosmology

It appears to be experiencing a quasi-spherical mass loss.

Brown dwarfs, which are neither stars nor planets, were first introduced to us 27 years ago. Now it is time to meet a new one because astronomers have discovered a brown dwarf under the Ophiuchus Disk Survey employing ALMA (ODISEA) project.

ODISEA project, which is intended to study the entire population of protoplanetary disks in the Ophiuchus Molecular Cloud, a group of astronomers led by Dary Ruiz-Rodriguez of the National Radio Astronomy Observatory (NRAO) have investigated “SSTc2d J163134.1–24006,” which was initially identified as a faint stellar object.

Researchers construct complex synthetic microbiome

Posted by in categories: biotech/medical, health

This can help engineer microbiome-based therapies in the future.

Researchers at Standford University have built from scratch the most complex and well-defined synthetic microbiome that will help us better understand the connections between the microbiome and human health, a university press release said.

The microbiome is a community of microorganisms that are found to cohabit in a given environment. The human gut has its own set of microorganisms that are markedly different from those on the skin.

These companies operate in strategically important areas such as semiconductors, manufacturing, energy, and minerals.

The Chinese government has selected 8,997 little-known industrial enterprises that will enjoy preferential treatment from central and provincial governments as the country prepares to supersede the technological prowess of the U.S., South China Morning Post.

How Exotic Atoms Can Transform Into Windows Into The Nature Of The Universe

Posted by in category: particle physics

The energy of the vacuum should have a gravitational effect on large atoms. But physicists’ attempts to measure it have puzzlingly come up empty.

Researchers devise a theoretical description of light-induced topological states

Posted by in categories: materials, particle physics

Topological materials that possess certain atomic-level symmetries, including topological insulators and topological semi-metals, have elicited fascination among many condensed matter scientists because of their complex electronic properties. Now, researchers in Japan have demonstrated that a normal semiconductor can be transformed into a topological semi-metal by light irradiation. Further, they showed how spin-dependent responses could appear when illuminated with circularly-polarized laser light. Published in Physical Review B, this work explores the possibility of creating topological semi-metals and manifesting new physical properties by light control, which may open up a rich physical frontier for topological properties.

Most ordinary substances are either , like metals, or insulators, like plastic. In contrast, can exhibit unusual behavior in which electrical currents flow along the surface of the sample, but not inside the interior. This characteristic behavior is strongly connected to topological properties inherent in the electronic state. Furthermore, a novel phase called a topological semi-metal provides a new playground for exploring the role of topology in condensed matter. However, the underlying physics of these systems is still being pondered.

Researchers at the University of Tsukuba studied the dynamics of excitations in zinc arsenide (Zn3As2) when irradiated with a laser with circular polarization. Zinc arsenide is normally thought of as a narrow-gap semiconductor, which means that electrons are not free to move around on their own but can be easily propelled by energy from an external light source. Under the right conditions, the material can show a special topological state called a “Floquet-Weyl semi-metal,” which is a topological semi-metal coupled with light. In this case, the can be carried in the form of quasiparticles called Weyl fermions. Because these quasiparticles travel as if they have zero mass and resist becoming scattered, Weyl fermions can move easily through the material.

Researchers just built a synthetic human gut microbiome. Now they can test it like never before

Posted by in categories: biotech/medical, neuroscience

Standford.

The microbiome is a community of microorganisms that are found to cohabit in a given environment. The human gut has its own set of microorganisms that are markedly different from those on the skin. Over the years, the study of the human gut microbiome has attracted interest after researchers have found it to play a role in neural development as well as response to immunotherapies when treating cancer.

Scientists find “hidden killer” causing cancer deaths

Posted by in category: biotech/medical

Air pollution may explain why non-smokers have been vulnerable to lung cancer, according to scientists’ findings presented at the European Society for Medical Oncology conference in Paris last weekend.

London-based Francis Crick Institute facilitated a study that found car fumes contain fine particulates, also known as PM2.5, with the capacity to awaken dormant lung cell mutations. These particulates can tip the cells into a cancerous state.

Francis Crick Institute Professor Charles Swanton, who presented the findings at the conference and led the study, said that although lung cancer is less likely to occur from air pollution rather than from smoking, patients have no control over the air they breathe.

MD Anderson: Many skin cancer tumors disappear with new therapy

Posted by in categories: biotech/medical, government

Sept. 12 (UPI) — More than six in 10 patients with an advanced stage of a common type of skin cancer saw their tumors nearly or completely disappear when treated with immunotherapy before surgery — results likely to change how physicians target these cancers.

That’s according to the University of Texas MD Anderson Cancer Center, which reported the findings Monday at the European Society for Medical Oncology Congress 2022 in Paris.

Each year, about 1 million people in the United States are diagnosed with squamous cell carcinoma of the skin, and resultant tumors may affect the eyes, ears, nose and mouth.
