Frozen samples are scientists’ gold
Our knowledge of causes and mechanisms of current and future diseases is on ice – not the perpetual ice of the polar caps but artificial ice. It is stored in biobanks at -80 to -160 °C.

Altering the ‘flavor’ of humans could help fight Malaria
A new study by Johns Hopkins researchers suggests that a specialized area of the mosquito brain mixes tastes with smells to create unique and preferred flavors. The findings advance the possibility, they say, of identifying a substance that makes “human flavor” repulsive to the malaria-bearing species of the mosquitoes, so instead of feasting on us, they keep the disease to themselves,…
The BMJ launches series to get the latest trial evidence into practice

‘Open Science’ paves pathway to develop Malaria drugs
Malaria remains one of the world’s leading causes of mortality in developing countries. Last year alone, it killed more than 400,000 people, mostly young children. An international consortium of researchers unveiled the mechanics and findings of a unique “open science” project for malaria drug discovery that has been five years in the making.

Evidence of Zika virus found in tears
Researchers have found that Zika virus can live in eyes and have identified genetic material from the virus in tears, according to a study from Washington University School of Medicine in St. Louis. The research, in mice, helps explain why some Zika patients develop eye disease, including a condition known as uveitis that can lead to permanent vision loss.

Researchers Find Herpes Strain in the Nervous System
There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring back and cause complications not typically associated…

Cardiac records highlight an enigma
Two new studies have focused on the impact of weekend care and discharge on heart patients within the NHS in England. In one, patients suffering atrial fibrillation (AF) who were admitted to a National Health Service (NHS) hospital over the weekend faced a higher risk of dying within five years than patients admitted during normal hours.

Zika: 1.6 million childbearing women are at risk
Research by scientists in the US and UK has estimated that up to 1.65 million childbearing women in Central and South America could become infected by the Zika virus by the end of the first wave of the epidemic. Researchers from the WorldPop Project and Flowminder Foundation at the University of Southampton and colleagues from the University of Notre Dame and University of Oxford have also found…

Antibodies identified that thwart Zika virus
Scientists at Washington University School of Medicine in St. Louis have identified antibodies capable of protecting against Zika virus infection, a significant step toward developing a vaccine, better diagnostic tests and possibly new antibody-based therapies. The work, in mice, helps clarify recent research that also identified protective Zika antibodies but lacked important details on how the…

New Biomarker for cancer immunotherapy?
The Ligand PD-L1 is one of the most important targets for cancer immunotherapy with checkpoint inhibitors. But not all tumors have sufficient quantities of PD-L1 ligands on their surface. Scientists from the German Cancer Consortium (DKTK) have now shown that different types of cancer possess different quantities of PD-L1-Gen copies. Genetic analysis of the PD-L1 gene may in the future help to…

How the brain improves motor control
Adaptation in reaching - gradual improvement of motor control in response to a perturbation - is a central issue in motor neuroscience.However, even the cortical origin of errors that drive adaptation has remained elusive. In a new paper Inoue, Uchimura and Kitazawa have shown that error signals encoded by motor cortical neurons drive adaptation in reaching.

Biotherapeutics strike cancer cell growth
Many drug treatments do not work due to their poor ability to reach their intended targets inside patients’ cells. To address this, researchers at Cardiff University’s Schools of Pharmacy and Pharmaceutical Sciences, and Biosciences have designed a highly efficient method to improve the delivery of therapeutic molecules into diseased cells such as those in stomach cancer, breast cancer and…

The ideal transport vehicle for next-gen vaccines?
Most people recoil at the thought of ingesting E. coli. But what if the headline-grabbing bacteria could be used to fight disease? Researchers experimenting with harmless strains of E. coli — yes, the majority of E. coli are safe and important to healthy human digestion — are working toward that goal. They have developed an E. coli-based transport capsule designed to help next-generation…

Device allows 3D imaging with less radiation
Preliminary tests have demonstrated that a new device may enable existing breast cancer imagers to provide up to six times better contrast of tumors in the breast, while maintaining the same or better image quality and halving the radiation dose to patients. The advance is made possible by a new device developed for 3D imaging of the breast by researchers at the Department of Energy's Thomas…
