Researchers develop new technique to print tri-layered skin equivalents

Chronic wounds are deep and difficult to repair. Often, the top of the injury heals before the bottom, so the wound collapses in on itself. Over time, this can result in scar tissue and reduced skin function.

New nanoparticle adjuvant could lead to more powerful vaccines

A common strategy to make vaccines more powerful is to deliver them along with an adjuvant -; a compound that stimulates the immune system to produce a stronger response.

Daytime eating maintains circadian alignment, prevents glucose intolerance despite mistimed sleep

What are the effects of eating during the nighttime instead of the daytime? New research, focused on a simulation of night shift work, may hold implications for people eating at atypical times -; like those experiencing jet lag, circadian rhythm sleep disorders, or who tend to sleep late during the weekends.

Exposure to cannabis vapor reduces sperm counts and motility in two generations of mice

An intense but short-term exposure to cannabis vapor lowered sperm counts and slowed sperm movement, or motility, not only in the directly exposed male mice but also in their sons.

Creating a Biological Clock in a Test Tube

We speak to researchers from the UC San Diego Center for Circadian Biology about their latest research that led to the development of a biological clock in a test tube.

Integration of digital and molecular data could enable individualized prevention of disease

Analyzing molecular characteristics and their variation during lifestyle changes, by combining digital tools, classical laboratory tests and new biomolecular measurements, could enable individualised prevention of disease.

Researchers identify a new approach to triggering differentiation in acute myeloid leukemia

In the late 1980s, scientists developed a revolutionary approach to treating acute myeloid leukemia (AML), a type of blood cancer. Called differentiation therapy, it amounted to a bona fide cure for many patients.

Fungal network growth in grasses made possible by cell wall remodeling

Scientists now have a deeper understanding of how a fungus develops a symbiotic lifestyle inside grass leaf and why the grass leaf fails to defend itself against the intruder, thanks to research coming from Massey University in New Zealand and the University of Münster in Germany.

Next-generation sequencing for minimal residual disease proven more sensitive than flow cytometry

In pediatric and young adult patients with acute lymphoblastic leukemia (ALL) treated with tisagenlecleucel (Kymriah), DNA sequencing-based detection of residual disease between three and 12 months accurately identified all patients who would eventually relapse, while other methods were less predictive.

Nanoparticles mimicking flu viruses to deliver large biological drug molecules

Nanoengineers from the University of California San Diego recently created a new and potentially efficient means to deliver messenger RNA (mRNA) into cells.

Experts create new software that determines a person’s past infections

Recent research suggested that grouping of pathogen-recognizing proteins on immune T cells might be vital in pinpointing if an individual had an infection in the past.

Scientists test the accuracy of enzymes that copy DNA under weightlessness

Researchers at Queen’s University boarded a modified Falcon 20 aircraft at Ottawa airport on May 22nd, 2019 as part of a scheduled “vomit comet” flight. In this mode of flight, the plane repeatedly climbs in a steep parabola to 8 km, alternating with a freefall descent.
