A remarkably high diversity of the wingless long-horned beetles in the mountains of northern Borneo is reported by three Czech researchers from the Palacký University, Olomouc, Czech Republic. Apart from the genera and species new to science, the entomologists report the first case of reproduction by live birth in this rarely collected group of beetles. The study was published in the open access journal ZooKeys.

A doctoral student at the University of Pennsylvania has identified a new species of fossil dog. The specimen, found in Maryland, would have roamed the coast of eastern North America approximately 12 million years ago, at a time when massive sharks like megalodon swam in the oceans.

It's been more than 30 years since the invention of 3-D printing, and yet in some ways the technology is still a frontier of unexplored potential.

Three-dimensional printing -- and additive manufacturing in general -- is the process of depositing material, layer by layer, in patterns determined by computer software, to precisely fabricate a three-dimensional object. The technology has been used to make hip and dental implants, as well as architectural models and aerospace tools, including a socket wrench that astronauts recently printed aboard the International Space Station.

Attosecond light pulses in the extreme ultraviolet have drawn a great deal of attention due to their ability to interrogate electronic dynamics in real time. Nevertheless, to follow charge dynamics and excitations in materials, element selectivity is a prerequisite, which demands such pulses in the soft X-ray region, above 200 eV, to simultaneously cover several fundamental absorption edges of the constituents of the materials.

New research from the University of Pittsburgh School of Medicine suggests two simple ways dermatologists can make patients more comfortable during full-body skin cancer checks: respect patient preferences for the physician's gender as well as whether, and how, they prefer to have their genitals examined. The findings are published online today in JAMA Dermatology.

DENVER - Immunohistochemistry (IHC) is an effective tool that can be used for identifying proto-oncogene 1 receptor tyrosine kinase (ROS1) gene rearrangements and screening patients for the administration of the targeted therapy crizotinib, a small-molecule tyrosine kinase inhibitor.

• Researchers exposed rodents' lung and skin cells to different oxygen concentrations to observe how they react
• Despite popular belief that sensitivity to oxidative stress is associated with a decreased lifespan, the study found this was not the case in the majority of rodents
• Laboratory mouse strains are atypically sensitive to oxidative stress compared to wild mice and may not be a good model for aging research
• Findings offer new opportunities to further investigate how to slow down the ageing process in humans

A new UBC-developed method to isolate cancer cells that have escaped from a tumour could soon pave the way for improved diagnosis and treatment.

The simple process involves a special device that squeezes cells in a blood sample through tiny funnels, which drive the cancer cells and blood cells into separate streams based on differences in their size and softness.

ANN ARBOR, Mich. -- Remember the game Operation? You need to carefully remove the body part without nicking the sides or the buzzer will sound.

Only imagine pulling out the funny bone when it's surrounded by vessels controlling urinary and sexual function. That's the issue when treating prostate cancer.

The prostate is a tiny organ surrounded by critical structures. When radiation treatments deliver dose to any of these structures, it can sometimes lead to problems such as erectile dysfunction and bladder or rectal irritation.

Their successful application of this method to a recently reported, randomised clinical trial on cardiovascular diabetes & ethanol, is outlined in a paper that has just passed peer review on open science publishing platform F1000Research.

An international team of scientists led by researchers from the Lomonosov Moscow State University succeeded to clarify the molecular mechanism of a drug created in Russia and designed to prevent the damaging of cell mitochondria by reactive oxygen species. This work is published in the journal Oxidative Medicine and Cellular Longevity.

In a massive analysis of DNA samples from more than 13,000 U.S. soldiers, scientists have identified two statistically significant genetic variants that may be associated with an increased risk of post-traumatic stress disorder (PTSD), an often serious mental illness linked to earlier exposure to a traumatic event, such as combat and an act of violence.

In what is considered one of the oldest and most important archaeological digs in North America, scientists have uncovered what they believe are the bones of a 13,000- to 14,000-year-old ancient, extinct species of bison at the Old Vero Man Site in Vero Beach, Fla. Archaeologists from Florida Atlantic University's Harbor Branch Oceanographic Institute made this discovery just 10 feet below the ground's surface during the final stretch of the 2016 excavation efforts at the Vero Beach site.

An unprecedented molecular view of the critical early events in gene expression, a process essential for all life, has been provided by researchers at Georgia State University, the University of California at Berkeley and Northwestern University.

The quest for a synthetic heart valve that faithfully mimics the original is a step closer to its goal with the Rice University find that a natural polymer called hyaluronan, one of the chief components of skin and connective tissue, can serve as a versatile template for growing spongiosa, the middle tissue layer in the valve's leaflets.

The tissues in heart valves, which typically work for decades without pause, are some of the strongest and most durable in nature and the options to repair or replace them are limited.
