A new study finds that a small group of microorganisms may be influencing sperm motility.

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.

An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb) kills upwards of 1.6 million people a year, making it one of the leading causes of death by an infectious agent worldwide -- and that number is only growing larger. How, exactly, Mtb evades the immune system isn't yet known, but a collaborative team of researchers recently discovered something surprising: prior exposure to a genus of bacteria called Mycobacterium seems to remodel the first-line defenders in the body's immune system.

A research team has for the first time discovered anomalous meter-sized rocks on the lunar surface that are covered in dust and presumably exhibit unique properties -- such as magnetic anomalies. These findings help to understand the processes that form and change the lunar crust.

Researchers have used DNA origami, the art of folding DNA into desired structures, to show how an important cell receptor can be activated in a previously unknown way. The result opens new avenues for understanding how the Notch signalling pathway works and how it is involved in several serious diseases.

New research has been published that identifies positive steps towards a better understanding of antimicrobial resistance (AMR), specifically in hospital-acquired pneumonia (HAP).

A flagship seven-year study that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater has now been published.

As the home of many beloved snack companies, Pennsylvania values its potatoes. Tasty tubers across the state may face the threat of newly identified pathogen strains, though, according to researchers who made the finding and aim to develop management strategies.

What did people eat on the west coast of Scandinavia 10,000 years ago? A new study of the DNA in a chewing gum shows that deer, trout and hazelnuts were on the diet. It also shows that one of the individuals had severe problems with her teeth.

Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies -- a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys -- target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells.

Scientists have known about a particular organelle in plant cells for over a century. However, scientists have only now discovered that organelle's key role in aging.

A new study is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare.

Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.

Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology.

To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health.

A team of scientists discovered the secrets of cell variability in our bodies. The findings of this research are expected to have far-reaching effects, such as improvement in the efficacy of chemotherapy treatments, or set a new paradigm in the study of antibiotic-resistant bacteria.

Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? In a new study, researchers describe a potential COVID-19 test inspired by bioluminescence. Using a molecule found in crustaceans, they have developed a rapid approach that detects SARS-CoV-2 protein comparably to one used in vaccine research.
