Kofi Annan, l'ancien secrétaire général de l'ONU et prix Nobel de la paix, est mort à l'âge de 80 ans
The Russian space program gets a lot of credit for flying the first woman in space. In fact, the Soviet Union flew the first two women: Valentina Tereshkova in 1963 and Svetlana Savitskaya in 1982. NASA waited until the space shuttle era before selecting female astronauts, and Sally Ride did not become the first American woman in space until 1983.
However, since Ride broke the US space gender barrier 35 years ago, 50 other American women have flown into space. By contrast, just two other women from Russia have flown into space since then, Yelena Kondakova (1994 and 1997) and Yelena Serova (2014). Two women from China, Japan, and Canada have also flown into space, as well as one woman each from the countries France, India, Italy, South Korea, and the United Kingdom.Widening gap
This disparity seems likely to only widen in the future. Of NASA's last two astronaut classes, in 2013 and 2017, nine of the 20 chosen candidates were women. Of Russia's last two classes in 2012 and 2018, just a single woman, Anna Kikina, was picked. Selected in 2012, Kikina was subsequently expelled from the cosmonaut corps in 2014 for unspecified reasons. After a public outcry, Kikina was reinstated, but it is not clear whether she will ever fly.
In mid-August 2018, Microsoft released the production Version 4.5 of F#, which supports the Span value type from .Net Core to improve code.[ Get started with functional programming, including examples in F#. • Discover 14 excellent reasons to use F#. | Keep up with hot topics in programming with InfoWorld’s App Dev Report newsletter. ]Current version: What’s new in F# 4.5
Span, aka Span<T>, enables the representation of contiguous regions in arbitrary memory. With Span, Microsoft wants F# to have better code generation particularly for byref-like constructions and full parity with .Net Core performance innovations. Interoperability with high-performance code also is a goal.
Palm oil is ubiquitous and is set to become more so over the next few decades. The oil is used in food, cleaning, and beauty products and as biofuel, so demand is set to grow rapidly. With this skyrocketing demand comes a need for the land on which to grow more oil palms—and a threat to the ecosystems currently using that land.
Currently, Southeast Asia is the oil palm hotspot, and the deforestation and ensuing damage in the region have been well publicized. But much of the future expansion may happen in Africa, introducing the likelihood of new conservation problems. A paper published in this week’s PNAS argues that there's a huge overlap between the land where oil palms could be grown and the land that houses the continent’s primates. “Large-scale expansion of oil palm cultivation in Africa will have unavoidable, negative effects on primates,” write Giovanni Strona and his colleagues.Growth in demand, loss in habitat
The tree that provides us with palm oil (which is pressed from its fruit) is a tropical species. Currently, palm oil agriculture uses approximately 20 million hectares. One million hectares (or 10,000 km2) is about half the area of New Jersey; 20 million is about the area of Nebraska. Most of these plantations are in Indonesia and Malaysia.
Wassyla Tamzali : " La condition des femmes dans le monde musulman est une question de volonté politique "
One of the least fun jobs when writing a scientific paper is coming up with a motivation. It should be easy and fun: look at this awesomely cool thing we did—aren’t the results interesting? Instead, we typically have to claim to reveal the secrets of the Universe, cure cancer, or protect the public. Preferably all three at the same time.
A recent paper (PDF) on using Wi-Fi as an environmental sensor has some really exciting results. But my heart shrunk three sizes after reading the following: “Traditional baggage check involves either high manpower for manual examinations or expensive and specialized instruments, such as X-ray and CT. As such, many public places (i.e., museums and schools) that lack of strict security check are exposed to high risk.”
As I said, the research is totally cool. It's just not likely to ever help with security unless molesting people with hip replacements is your version of improved security.
Mylan’s life-saving epinephrine auto-injector EpiPen now has a generic rival, the Food and Drug Administration triumphantly announced.
Teva Pharmaceuticals USA now has FDA approval to market a direct generic competitor of the device, as well as a version for pediatric patients, a generic EpiPen Jr. Both products are used in emergency situations to auto-inject a dose of epinephrine into a person’s thigh to thwart deadly allergic reactions, namely anaphylactic shock.
The approval comes years after Mylan outraged patients and lawmakers by ruthlessly hiking the price of its product by more than 400 percent. Mylan purchased the rights to EpiPen in 2007 and gradually raised the list price from about $50 per auto-injector to slightly over $600 for a two-pack. The move boosted EpiPen profits to $1.1 billion a year. In step, Mylan CEO Heather Bresch saw her salary soar by millions, reaching nearly $19 million in 2015—a point lawmakers hammered her for during a House Oversight committee hearing in September of 2016.
