Scientists at Columbia University’s Mailman School of Public Health developed a system to accurately predict the geographic spread of seasonal influenza in the United States up to six weeks ahead of time.
Holography, like photography, is a way to record the world around us. Both use light to make recordings, but instead of two-dimensional photos, holograms reproduce three-dimensional shapes. The shape is inferred from the patterns that form after light ricochets off an object and interferes with another light wave that serves as a reference. When created with X-ray light, holography can be an…
Using self-sampling followed by HPV testing, more than twice as many women at risk of developing cervical cancer could be identified and offered preventive treatment. This is shown by researchers at Uppsala University in the first randomised study in the world comparing two ways of identifying cervical cancer, published in the British Journal of Cancer.
A powerful genome editing tool can be deployed as an ace DNA detective, able to sniff out DNA snippets that signal viral infections, cancer, or even defective genes. This genetic detective, developed in the laboratory of Howard Hughes Medical Institute (HHMI) Investigator Jennifer Doudna at the University of California, Berkeley, uses the genome-slicing system known as CRISPR. By combining the…
Indiana University researchers have made an important step forward in the design of drugs that fight the hepatitis B virus, which can cause liver failure and liver cancer. It's estimated that 2 billion people worldwide have had a hepatitis B virus infection in their lifetime, with about 250 million -- including 2 million Americans -- living with chronic infection. Although a vaccine exists, there…
No woman should die from cervical cancer. Indeed, cervical cancer is the deadliest, yet most preventable gynecologic malignancy. According to the American Cancer Society, there are 13,000 new cases of invasive cervical cancer leading to 4,100 cancer-related deaths each year in the United States. Unfortunately, many of these deaths could have been prevented with either regular screening with Pap…
A powerful antiviral protein may act as a checkpoint for keeping or ending a pregnancy. When exposed to Zika virus before birth, mouse fetuses with the protein commit cell suicide, while fetuses without it continued to develop. The result, published in Science Immunology, suggests that the protein, a receptor involved in immune cell signaling, plays a role in spontaneous abortions and other human…
Viral infections kill millions of people worldwide every year, but currently available antiviral drugs are limited in that they mostly act against one or a small handful of related viruses. A few broad-spectrum drugs that prevent viral entry into healthy cells exist, but they usually need to be taken continuously to prevent infection, and resistance through viral mutation is a serious risk. Now,…
For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter. The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it…
UV radiation has been known for a long time to be a risk factor for the development of skin cancer. Simultaneous infection with human papillomaviruses (HPV) has also been suspected to promote skin cancer, particularly in organ transplant recipients. Scientists from the German Cancer Research Center (DKFZ) have now been able to show for the first time in a natural system that papillomaviruses…
The WHO European Region is the only region worldwide where the number of new HIV infections is rising. With more than 160 000 people newly diagnosed with HIV across the Region, including more than 29 000 new cases from the European Union and European Economic Area (EU/EEA), this trend continued in 2016. One reason for this worrying trend: over half (51%) of the reported HIV diagnoses happen in a…
In a comprehensive and complex molecular study of blood samples from Ebola patients in Sierra Leone, published in Cell Host and Microbe, a scientific team led by the University of Wisconsin–Madison has identified signatures of Ebola virus disease that may aid in future treatment efforts. Conducting a sweeping analysis of everything from enzymes to lipids to immune-system-associated molecules,…
A novel vaccine against cancer-causing human papillomaviruses (HPV) is intended to help raise vaccination rates especially in developing countries. To this end, scientists from the German Cancer Research Center (DKFZ) in Heidelberg are developing a completely new vaccination concept based on a low-cost vaccine that protects from almost all known oncogenic HPV types. The project has now been…
Each year, public health officials monitor the spread of influenza to identify which flu strains need to go into that year’s vaccines and where outbreaks will occur. But it can be difficult to predict how bad a particular flu season will be until people actually start getting sick. A new flu forecasting tool built by scientists at the University of Chicago aims to make better predictions by…
Recent outbreaks of Zika virus have revealed that the virus causes brain defects in unborn children. But researchers from Washington University School of Medicine in St. Louis and the University of California, San Diego report that the virus could eventually be used to target and kill cancer cells in the brain.
Over recent years, virology, once medicine‘s step-child, moved into the limelight, pushed by impressive progress and pulled by globalisation-induced need for expertise in virus diagnostics and viral epidemics.
The Society for Virology (GfV) which promotes virology through the increase and exchange of research within German speaking countries, as well as via cooperation with other scientific societies, announced this year that a new test can unambiguously confirm the diagnosis of a Zika virus infection – leading to fast diagnosis and identification of an infection.
Saliva is no way to pass a Zika virus infection. According to researchers at the University of Wisconsin–Madison who conducted studies with monkeys, casual contact like kissing or sharing a fork or spoon is not enough for the virus to move between hosts.
A promising Zika vaccine is on its way. Themis Bioscience GmbH (Vienna, Austria), a company specialised in vaccine development, has announced that the firm will receive One milion pounds sterling in funding by the innovation agency of the United Kingdom, Innovate UK, for the further development of this prophylactic vaccine and the conducting of a Phase 1 clinical trial.
A saliva test developed by researchers at the Johns Hopkins Bloomberg School of Public Health nearly matches the performance of a blood test widely used to assess recent or past hepatitis E virus infections, a new study reports. The findings could offer an easier, less expensive alternative to gathering data for studying and eventually treating the disease, which infects an estimated 20 million…
Researchers have found a clue to how the ebola virus may remain in the eyes of patients suffering from uveitis – one of the more serious and common complications of the disease.
Summer colds might seem rare, but people are actually just as likely to catch one in the summer as in the winter.
By developing a new technique for labeling the gene segments of influenza viruses, researchers now know more about how influenza viruses enter the cell and establish cell co-infections - a major contributing factor to potential pandemic development.
Scientists from St. Jude Children’s Research Hospital and Fred Hutchinson Cancer Research Center have developed an algorithm that functions like a Rosetta Stone to help decipher how the immune system recognizes and binds antigens. The research should aid development of more personalized cancer immunotherapy and advance diagnosis and treatment of infectious diseases.
Ebola outbreaks are set to be managed quickly and efficiently – saving lives – with a new approach developed by an international team of researchers, including the University of Warwick, which helps to streamline outbreak decision-making.
