A new study offers insights into the powerful anticoagulants contained in the saliva of leeches most often used in medical ...

Discovery Allows 3D Printing of Sensors Directly on Expanding Organs

Mechanical engineers and computer scientists have developed a 3D printing technique that uses motion capture technology, similar to that used in Hollywood movies, to print electronic sensors directly ...

Microbes Might Manage Your Cholesterol

Researchers discover a link between human blood cholesterol levels and a gene in the microbiome that could one day help people manage their cholesterol through diet, probiotics, or entirely new types ...

In a series of experiments using human cancer cell lines, scientists say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel ...

Detecting Antibodies With Glowing Proteins, Thread and a Smartphone

To defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune disease, part of the ...

Nanosponges Could Intercept Coronavirus Infection

Nanoparticles cloaked in human lung cell membranes and human immune cell membranes can attract and neutralize the SARS-CoV-2 virus in cell culture, causing the virus to lose its ability to hijack ...

Immune Properties in Ancient DNA Found in Isolated Villages Might Benefit Humanity Today

Could remnants of DNA from a now extinct human subspecies known as the Denisovans help boost the immune functions of modern humans? An international study represents the first characterizations of ...

Personality Traits Linked to Toilet Paper Stockpiling

People who feel more threatened by COVID-19 and rank highly on scales of emotionality and conscientiousness were most likely to stockpile toilet paper in March 2020, according to a new ...

Unlocking PNA's Superpowers for Self-Assembling Nanostructures

Researchers have developed a method for self-assembling nanostructures with gamma-modified peptide nucleic acid, a synthetic mimic of DNA. The process has the potential to impact nanomanufacturing ...

High Doses of Ketamine Can Temporarily Switch Off the Brain

Researchers have identified two brain phenomena that may explain some of the side-effects of ketamine. Their measurements of the brain waves of sheep sedated by the drug may explain the out-of-body ...

Can Gut Microbiome Alter Drug Safety and Efficacy?

Researchers have developed an approach for studying how the gut microbiome chemically alters oral medications, unlocking possibilities for improving efficacy, reducing side effects, and creating ...

World's First Spherical Artificial Eye Has 3D Retina

Scientists have developed the world's first 3D artificial eye with capabilities better than existing bionic eyes and in some cases, even exceed those of the human eyes, bringing vision to ...

Neuroengineers have created a tiny surgical implant that can electrically stimulate the brain and nervous system without using a battery or wired power ...

First Systematic Report on the Tug-of-War Between DNA Damage and Repair

Scientists have screened almost 163,000 DNA mutations in 2,700 C. elegans roundworms to shed light on DNA damage. The results, published in Nature Communications, lead to the conclusion that mutation ...

New Smart Fabrics from Bioactive Inks Monitor Body and Environment by Changing Color

Researchers developed biomaterial-based inks that respond to and quantify chemicals released from the body or in the environment by changing color. Multiple inks can be screen printed onto clothes or ...

Poison is lethal all on its own -- as are arrows -- and together, they can take down the strongest opponents. Researchers have found an antibiotic that simultaneously punctures bacterial walls and ...

Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times. Now, researchers have ...
