Forests, carbon sinks cannot make up for delays in decarbonizing the economy, experts argue — ScienceDaily

To stabilize the Earth’s climate for people and ecosystems, it is imperative to ramp up natural climate solutions and, at the same time, accelerate mitigation efforts across the energy and industrial sectors, according to a new policy perspective published today in Science. Among their findings, the researchers warn that a ten-year delay in emissions reductions…

Machinery used in basic cell division does double duty as builder of neurons — ScienceDaily

Researchers at the San Diego branch of the Ludwig Institute for Cancer Research at University of California San Diego have identified an entirely new mechanism underlying the development and structure of the nervous system during embryogenesis. The findings, publishing in the February 28, 2019 issue of Developmental Cell, focus on the dynamic coupling of microtubule…

New method fills critical need to measure large-scale quantum correlation of single photons — ScienceDaily

For the first time, researchers have demonstrated a way to map and measure large-scale photonic quantum correlation with single-photon sensitivity. The ability to measure thousands of instances of quantum correlation is critical for making photon-based quantum computing practical. In Optica, The Optical Society’s journal for high impact research, a multi-institutional group of researchers reports the…

Nicotine may harm human embryos at the single-cell level — ScienceDaily

Nicotine induces widespread adverse effects on human embryonic development at the level of individual cells, researchers report February 28th in the journal Stem Cell Reports. Single-cell RNA sequencing of human embryonic stem cell (hESC)-derived embryoid bodies revealed that 3 weeks of nicotine exposure disrupts cell-to-cell communication, decreases cell survival, and alters the expression of genes…

How prostate cancer becomes treatment resistant — ScienceDaily

The development of effective anti-androgen therapies for prostate cancer is a major scientific advance. However, some men who receive these targeted treatments are more likely to develop a deadly treatment-resistant prostate cancer subtype called neuroendocrine prostate cancer (NEPC). No effective treatment for NEPC exists. Now, scientists from Sanford Burnham Prebys Medical Discovery Institute (SBP) have…

Pan-filovirus T-cell vaccine protects mice from Ebola and Marburg — ScienceDaily

Vaccines that induce protective T-cell responses could protect against members across the filovirus family, according to a study published February 28 in the open-access journal PLOS Pathogens by Tomáš Hanke of the University of Oxford, Bette Korber of the Los Alamos National Laboratory, and colleagues. Developing an effective vaccine against filovirus outbreaks is an important…

Researchers observe an unusual quantum Hall effect in the old three-dimensional material — ScienceDaily

Researchers at The University of Manchester in the UK, led by Dr Artem Mishchenko, Prof Volodya Fal’ko and Prof Andre Geim, have discovered the quantum Hall effect in bulk graphite — a layered crystal consisting of stacked graphene layers. This is an unexpected result because the quantum Hall effect is possible only in so-called two-dimensional…
