A new 12-year U.S. study shows the most frequent involve drugs used to stimulate ovaries, but it suggests problems are rarely fatal.
The investment made by Nestle Health Science, a subsidiary of Nestle, will help fund the next stage of development for the startup's CDI treatment.
These findings could shed light on related Alzheimer's protein.
A protein could be a universal therapeutic target for treating human diseases like brain cancer, Ebola, Influenza, Hepatitis and superbug bacteria.
Scientists have created primordial germ cells – cells that will go on to become egg and sperm – using human embryonic stem cells.
One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bacteria is still a puzzle to scientists.
A new instrument could someday build replacement human organs the way electronics are assembled today: with precise picking and placing of parts.
Neuroscientists have proposed that brain cells come in different subtypes that have different properties and responsibilities.
Scientists have found a new way to help Type 1 diabetes patients defend themselves against life-threatening low blood sugar.
Investigators have developed a method for detecting unwanted DNA breaks—across the entire genome of human cells—induced by the popular gene-editing tools called CRISPR-Cas RNA-guided nucleases (RGNs).
Chemists at The Scripps Research Institute have invented a powerful method for joining complex organic molecules that is extraordinarily robust.
Brazilian organizers of the 2016 Olympics are creating a task force to deal with a so-called "super bacteria" discovered in Olympic sailing waters.
Researchers have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations.
Fingerprint examination, though in use for more than 100 years, has until recently undergone surprisingly little scientific scrutiny. Now, a newly published paper provides important new insight into what specific, visual aspects of fingerprint pairs make their analysis more or less difficult.
Despite large international efforts to catalogue the genes that influence the stature of humans, knowledge on genetic determinants of adult body height is still incomplete. Now, DNA-based prediction of taller-than-average body height is feasible, as reported by researchers.
Fingerprints are not the only thing that killers can leave behind — add cat hair to that list. A British university said that its DNA database of British felines helped convict a man of manslaughter, illustrating how the genetic material of pets can be used by crime scene investigators.
A new study reports the first proof of cancer’s ability to fuse with blood, giving cancer the ability to travel and seeding sites of metastasis around the body. The work used DNA fingerprinting of a bone marrow transplant patient with cancer, along with DNA fingerprinting of the patient’s bone marrow donor, to show that metastatic cancer cells carried parts of both genomes, fused together into a hybrid cancer cell.
Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. Researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules.
DNA evidence is invisible and remarkably easy to transfer, making it possible for a sample to be spilled or even planted on a piece of evidence. A researcher has developed a solution that permanently marks DNA samples to prevent contamination.
For 42 years, Muammar Gaddafi ran a ruthless regime in Libya. Although deposed in 2011, one of his sad legacies is a series of mass graves containing an estimated 20,000 human remains. But with this discovery comes a chance to solve decades-old missing person cases. Using forensic DNA identification technologies, scientists employed by the Libyan government will soon begin this process. But first they need the tools and the training.
The Promega PowerPlex Y23 System is now approved for use in laboratories that generate DNA records for the National DNA Index System (NDIS). The PowerPlex Y23 System is a rapid human identification Y-chromosome short tandem repeat (Y-STR) assay for forensic casework, offender databasing, and relationship testing.
For centuries, the fate of the original Otomí inhabitants of Xaltocan, the capital of a pre-Aztec Mexican city-state, has remained unknown. Researchers have long wondered whether they assimilated with the Aztecs or abandoned the town altogether. According to new anthropological research, the answers may lie in DNA.
It was an archaeological hoax that fooled scientists for decades. A century on, researchers are determined to find out who was responsible for Piltdown Man, the missing link that never was. Speculation about who did it rages to this day. Now scientists are marking the anniversary with a new push to settle the argument for good.
Increasing pressure requires labs to find ways to do more with less—analyze more DNA and do so faster and at less expense. To reach those goals, forensics labs need new tools that help them collect more samples, analyze them at higher throughout, and also churn out more accurate results.
One of the overarching trends for Life Sciences has been the need for biocompatible materials and processes. For analytical and diagnostic systems, the word biocompatibility refers to the interaction between any component in the system and the biological sample
