April 9, 2020 -- The Lancet commentary "Centring sexual and reproductive health and justice in the global COVID-19 response" highlights the detrimental impact of the global COVID-19 pandemic response on sexual and reproductive health and rights (SRHR). The piece emphasizes the threat to SRH services, caused by policies designating these services as non-essential and diverting resources, and calls for vigilance from the SRH community to prevent access to these services from being lost.
Nano-catalysts usually have higher catalytic activity than traditional bulk catalysts. And it is widely acknowledged that the smaller the particle size of the active component is, the higher the activity would be. However, the active component with small size tends to agglomerate or further grow into large particles.

While everybody agrees that our blue planet is rich in water, this observation is at odd, first, with the exploration of other rocky planets, genuinely lacking surface water, and second, with the idea of a giant impact between the proto-Earth and a planetary embryo the size of Mars that created the Moon. Such a catastrophic event should have vaporized any pre-existing water, leaving behind a dry Earth.
One of the major objectives in biology is to understand the factors and mechanisms that have led to the diversification of species on earth. Plant-feeding insects are the most diversified group of organisms on earth, and they account for more than 40% of all insects. There have been numerous studies into the diversification patterns and driving forces looking at host plants, however, interactions with other organisms had yet to be accounted for.

WASHINGTON, D.C., April 10 - Agricultural Research Service (ARS) scientists and their colleagues have discovered a gene that can be used to develop varieties of wheat that will be more resistant to Fusarium Head Blight (FHB), a disease that is a major threat both overseas and to the nation's $10 billion annual wheat crop.
PHILADELPHIA--A prospective "PARP inhibitor" drug that has struggled to show effectiveness in clinical trials against cancers can be structurally modified to greatly increase its power to kill tumor cells, researchers from Penn Medicine report this week in Science.
The team also showed that PARP inhibitor compounds can be "tuned" in the opposite way so that they inhibit PARP-1 enzymes without killing cells, thus potentially making this class of drugs more useful for treating heart disease and other non-cancer conditions where inhibiting PARP-1 is the goal.
Imagine the advances to predictive modeling if you could infer something about how light amplifies colors in a bird's plumage from the way seismic waves propagate through mountain systems.
That's a bit of hyperbole that nevertheless suggests the "beautiful" utility of new mathematical formulas devised by Princeton Professor of Chemistry Salvatore Torquato and sixth-year graduate student Jaeuk Kim of the Department of Physics as they advance our understanding of how different types of waves behave inside materials.
CHICAGO (April 9, 2020): Within a month of the University of California San Francisco (UCSF) Health treating its first patient with coronavirus disease 2019 (COVID-19) on Feb. 3, UCSF surgeons began formulating a plan to respond to the pandemic and help manage the health care system's available resources.
