Align or die: Revealing unknown mechanism essential for bacterial cell division

Posted by in category: materials

A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto “dying to align”: Misaligned filaments “die” spontaneously to form a ring structure at the center of the dividing cell. The study, led by the Šarić group at the Institute of Science and Technology Austria (ISTA), was published in Nature Physics. The work could find applications in developing synthetic self-healing materials.

Research team uses tunable laser to develop straightforward broadband spectroscopy method with Hz-level precision

Posted by in category: particle physics

Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser technology have further enhanced its capabilities. There are two main types of laser spectroscopy: frequency comb-based laser spectroscopy and tunable continuous-wave (CW) laser spectroscopy.

Newly discovered X-ray binary system contains a white dwarf, observations find

Posted by in category: space

Astronomers from the Pennsylvania State University (PSU) and elsewhere have observed an X-ray binary system known as CXOU J005245.0–722844. They detected an X-ray outburst from this binary and found that it harbors a white dwarf star. The findings were presented in a research paper published August 2 on the pre-print server arXiv.

Scientists find oceans of water on Mars. It’s just too deep to tap

Posted by in category: space

Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet’s surface.

New U.N. Cybercrime Treaty Could Threaten Human Rights

A recently adopted United Nations treaty could lead to invasive digital surveillance, human rights experts warn.

By Kate Graham-Shaw

NEW YORK CITY —The United Nations approved its first international cybercrime treaty yesterday. The effort succeeded despite opposition from tech companies and human rights groups, who warn that the agreement will permit countries to expand invasive electronic surveillance in the name of criminal investigations. Experts from these organizations say that the treaty undermines the global human rights of freedom of speech and expression because it contains clauses that countries could interpret to internationally prosecute any perceived crime that takes place on a computer system.

“Alien Biology” Discovered: Bacteria’s Floating Genes Leave Scientists Baffled

Posted by in categories: alien life, genetics, health

Columbia researchers discovered that bacteria can create free-floating, temporary genes outside their chromosomes, challenging the long-held belief that all genetic instructions are contained within the genome. This finding opens the possibility that similar genes could exist in humans, potentially revolutionizing our understanding of genetics and gene editing.

Since the genetic code was first deciphered in the 1960s, our genes have appeared like an open book. By interpreting our chromosomes as linear sequences of letters, akin to sentences in a novel, we can identify the genes within our genome and understand how changes in a gene’s code influence health.

This linear rule of life was thought to govern all forms of life—from humans down to bacteria.

Custom Implants on Demand? Bandages for the Heart? 3D Printing Method Makes It Possible

Posted by in categories: 3D printing, biotech/medical

University of Colorado at Boulder News

In the quest to develop life-like materials to replace and repair human body parts, scientists face a formidable challenge: Real tissues are often both strong and stretchable and vary in shape and size.

A CU Boulder-led team, in collaboration with researchers at the University of Pennsylvania, has taken a critical step toward cracking that code. They’ve developed a new way to 3D print material that is at once elastic enough to withstand a heart’s persistent beating, tough enough to endure the crushing load placed on joints, and easily shapable to fit a patient’s unique defects.

Chemists synthesize plant-derived molecules that hold potential as pharmaceuticals

Posted by in category: biotech/medical

MIT chemists have developed a new way to synthesize complex molecules that were originally isolated from plants and could hold potential as antibiotics, analgesics, or cancer drugs.
