Faster, cheaper, better: improved gene therapy tool production

The heart of modern therapy is increasingly personalized and targeted at specific cellular or genetic deficits. This requires gene therapy, in many cases. A new study, published on 19 September 2019 in the journal Nature, describes an improved way to produce purified gene carrier viruses called AAVs cheaply and quickly, from the culture medium.

Forbidden fruit: Scientists venture into “embryoid” manufacturing

After working on stem cells for several years, scientists have now announced that they have found a way to synthesize structures that look like very primitive human embryos. While some hailed the discovery, others questioned the ethical basis of manufacturing synthetic humans.

Early detection method for pinpointing molecular signatures of Lyme disease

When researchers examined the mitochondrial DNA of Ötzi, a man entombed in ice high in the Tyrolean Alps some 5,300 years ago, they made a startling discovery.

Humic substances extracted from coal can help fight viruses

Scientists from Russia demonstrated a novel approach leveraging the combination of high-resolution mass spectrometry and chemoinformatics to identify biologically active molecular components of humic substances extracted from coal, and discovered substances with antiviral activity against the tick-borne encephalitis virus.

Simple technique to choose the sex of offspring by separating X and Y sperm

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study by Masayuki Shimada and colleagues at Hiroshima University, published on August 13 in the open-access journal PLOS Biology. The study was performed in mice, but the technique is likely to be widely applicable to other mammals as well.

Receptor in the uterus can detect sperm molecule, aids in sperm survival

Why does it take 200 million sperms to fertilize a single egg? The single sperm that reached the finished line has successfully survived multiple checkpoints within the female reproductive tract, dubbed as pre-fertilization events. Now, a new study shows that the uterus contains receptors that facilitate sperm survival.

Gay men in China eight times more likely to face social discrimination

A new study highlights the importance of social and emotional support in homosexual men. Young adult gay men in China were found to be eight times more likely to feel rejected and criticized, fueling feelings of interpersonal sensitivity and loneliness.

Rutgers-led study sheds light on the origins of metabolism

A Rutgers-led study sheds light on one of the most enduring mysteries of science: How did metabolism – the process by which life powers itself, by converting energy from food into movement and growth – begin?

Data collected by ESHRE show rise in use of IVF in infertility treatment

The latest annual data collected by ESHRE from European national registries show another rise in the cumulative use of IVF in the treatment of infertility, although success rates after IVF or ICSI appear to have reached a peak, with pregnancy rates per started treatment calculated at 27.1% after IVF and 24.3% after ICSI.
