Proper chromosome segregation into two future daughter cells requires the mitotic spindle to elongate in anaphase. However, although some candidate proteins are implicated in this process, the molecular mechanism that drives spindle elongation in human cells has been unknown, until now! Researchers at the Croatian Ru?er Boškovi? Institute (RBI) have discovered the exact molecular mechanism of bridging microtubules sliding and its role in proper distribution of genetic material during cell division.

Researchers have fabricated a magnetically driven rotary microfilter that can be used to filter particles inside a microfluidic device. They made the tiny turning filter by creating a magnetic material that could be used with a very precise 3D printing technique known as two-photon polymerization.

What will the Earth be like for our children and grandchildren, as temperatures continue to rise? We can be fairly certain of some things: Some regions will become inhospitable, as heat drives their inhabitants away or causes massive declines and changes in their ecosystems. Many other physical, chemical and biological processes will also be affected by rising temperatures that threaten critical ecosystem services such as food production, biodiversity and energy security.

The study found that rebates were associated with increases in out-of-pocket costs for patients by an average of $6 for those with commercial insurance, $13 for Medicare patients and $39 for the uninsured.

In 1943, two scientists named Max Delbrück and Salvador Luria conducted an experiment to show that bacteria can mutate randomly, independent of external stimulus, such as an antibiotic that threatens a bacterial cells' survival. Today the Luria-Delbrück experiment is widely used in laboratories for a different purpose--scientists use this classic experiment to determine microbial mutation rates.

Freiburg researchers find new mechanism for classical behavior of many-particle quantum systems.

Researchers reporting in Advanced Photonics demonstrate the conversion of infrared images to the visible, using ultrathin and transparent semiconductor nanocrystals.

A new article analyzes Chile's transition in 1990 from dictatorship to democracy, the nature of democracy between 1990 and 2019, and the appearance of several social movements geared to expanding this democracy.

Dr. Igor Ivanishin, a postdoctoral researcher in the Harold Vance Department of Petroleum Engineering at Texas A&M University, has firsthand experience with the frustrations of oil production. He spent nine years as a hydraulic fracturing engineer with operating and service companies in Russia. A few years ago, he came to Texas A&M to get his doctoral degree while delving into a reoccurring recovery problem in carbonate reservoirs: why don't they produce oil as predicted?

A group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate elicited durable neutralizing antibody responses to SARS-CoV-2 in pre-clinical research. There were no adverse effects.

Instead of looking at the reasons child welfare caseworkers leave their jobs, Oregon State University researchers examined the common factors among workers who stay in the field, and what makes them feel most satisfied in their work.

Evaluation of three COVID-19 vaccine candidates in 2020-21 during a worldwide pandemic was unprecedented in terms of urgency and scope. Responsibility for the safety, integrity and scientific validity of U.S. trials fell to 12 experts of the federally appointed COVID-19 Vaccine Data and Safety Monitoring Board, who in turn report to an oversight group. This team has now taken the unusual step of publishing details of their review process in The Journal of Infectious Diseases.

For the first time, researchers have used precariously-balanced rocks to set the formal design earthquake motions for a major existing engineered structure--the Clyde Dam, the largest concrete dam in New Zealand.

An underwater archaeologist from The University of Texas at Arlington is part of a research team studying 9,000-year-old stone tool artifacts discovered in Lake Huron that originated from an obsidian quarry more than 2,000 miles away in central Oregon. The obsidian flakes from the underwater archaeological site represent the oldest and farthest east confirmed specimens of western obsidian ever found in the continental United States.

New research from UC Davis suggests that remembering a song in your head is more than a passing nuisance -- it plays an important role in helping memories form, not only for the song, but also related life events.

As threats against female journalists rise, a researcher examines the damage done by the Hollywood trope of the unethical female reporter who trades sex for information.

A new study shows political partisans may engage in greater victim blaming for sexual assault crimes, especially when the members of their political party are accused. The more Republicans and Democrats identified with belonging to their political party and reported feeling defensive when members from their political party are criticized, the more accepting they were of common sexual assault myths and the less likely to perceive sexual assault as a serious issue.

In a new study, North Carolina State University researchers demonstrated they could print layers of electrically conductive ink on polyester fabric to make an e-textile that could be used in the design of future wearable devices.

In 2019, on a small island in coastal South Carolina, biologists discovered an animal migration phenomenon that was difficult to believe. Nearly 20,000 whimbrel were stopping at Deveaux Bank along their migration north -- half the estimated eastern population of the declining shorebird.
