At 1:03am on Monday 5 December, scientists at the National Ignition Facility in California aimed their 192 beam laser at a cylinder containing a tiny diamond fuel capsule.
That powerful burst of laser light created immense temperatures and pressures and sparked a fusion reaction - the reaction which powers the sun.
The National Ignition Facility (NIF), part of the Lawrence Livermore National Laboratory (LLNL), had done such experiments before, but this time the energy that came out of the reaction, was more than the laser power used to trigger it.

They saw an opportunity during Covid. Their experiences offer lessons for laid-off tech workers who may be thinking about striking out on their own.

A team whose venture-backed startup was inspired by a map they created for trick-or-treaters. A tech-company product manager who decided to quit his job during an eight-state road trip. A website developer who saw an opportunity to help small businesses reach customers online.
These are among the entrepreneurs who created new businesses during the Covid-19 pandemic, a time when the highest number of Americans since at least the mid-2000s took the first steps to launch a new venture.

Instead of sucking planet-warming carbon dioxide from the atmosphere, some scientists are looking to capture it from the oceans.
CLIMATEWIRE | There's a growing consensus among climate scientists that in order to avoid the worst effects of global warming, humanity has to find a way to sequester carbon dioxide — and most efforts to date have focused on removing CO2 from the atmosphere.
But two ongoing efforts — including one from the Massachusetts Institute of Technology — have turned to the oceans, rather than the air. And if successful, the scientists say the process could significantly cut the cost of using carbon capture to fight global warming.

Metagenomic sequencing can help detect unknown pathogens, but its widespread use faces challenges.
On December 18, 2019, Wuhan Central Hospital admitted a patient with symptoms common for the winter flu season: a 65-year-old man with fever and pneumonia. Ai Fen, director of the emergency department, oversaw a typical treatment plan, including antibiotics and anti-influenza drugs.
Six days later, the patient was still sick, and Ai was puzzled, according to news reports and a detailed reconstruction of this period by evolutionary biologist Michael Worobey. The respiratory department decided to try to identify the guilty pathogen by reading its genetic code, a process called sequencing. They rinsed part of the patient’s lungs with saline, collected the liquid, and sent the sample to a biotech company. On December 27, the hospital got the results: The man had contracted a new coronavirus closely related to the one that caused the SARS outbreak that began 17 years before.

When the Sun shines over the landscape at just the right angle, the lunar surface comes alive.
The dynamic interplay of light and shadow across the lunar face is a perpetual source of visual wonder — and, sometimes, puzzlement.
Nearly 40 years ago, Terry Atwood of Shreveport, Louisiana, saw one such display in the crater Hypatia. The feature lies in a tiny promontory of equatorial lunar highland, just south of the Apollo 11 landing site in Mare Tranquillitatis (Sea of Tranquillity). The crater’s name honors Hypatia of Egypt (circa a.d. 370–415), the first woman known to have made a substantial contribution to the development of mathematics.

The first decade of the International Space Station was the decade of construction. The second decade moved from initial studies to fully using the orbiting lab. We have now entered the decade of results.
With more than 20 years of experiments now conducted on the station, more breakthroughs are materializing than ever before.

No “Innovation Show Case Day” do projeto Nextlap, Érica Liberato, consultora em sustentabilidade, falou sobre a evolução dos riscos globais entre 2007 e 2020.
Para a consultora, o conceito de sustentabilidade “foi-se miscigenando ao longo do tempo”, sublinhando que o “tripé” da sustentabilidade, que antes era muito mais setorizada, acabou sendo, ao longo do tempo, “miscigenada”
Érica Liberato destacou a economia donut, que “trabalha com os limites da natureza”. Ou seja “como é que conseguimos evoluir ou crescer, desenvolver a economia dentro dos limites da natureza, mas também abarcando as necessidades sociais dos países e das organizações”, afirmou, explicando que, quando esta teoria foi lançada, “pareceu muito utópico essa ideia”, mas que já existem governos (na Holanda e na Costa Rica, por exemplo), que estão a trabalhar na economia donut.

Para colmatar as atuais lacunas, um novo estudo detalha que a Europa terá de aumentar o seu talento tecnológico feminino em mais de 1,6 milhões, alcançando um equilíbrio de 40/60, até 2027.
Um novo estudo revela que, se a percentagem de mulheres em empregos tecnológicos duplicasse até 2027, o PIB da União Europeia poderia aumentar em até 600 mil milhões de euros.
Segundo o estudo, realizado pela McKinsey & Company junto de mais de 60 milhões de trabalhadores na Europa, apenas 22% das mulheres europeias ocupam cargos tecnológicos em empresas.
