中国首次火星探测任务命名为天问一号 | 一周看点








The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan (about 340-278 BC), one of the greatest poets of ancient China.


In Tianwen, Qu Yuan raised a series of questions in verse involving the sky, stars, natural phenomena, myths and the real world, showing his doubts about some traditional concepts and the spirit of seeking the truth.


CNSA also unveiled the logo of Chinas planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.


China plans to launch the Mars probe in 2020, aiming to complete orbiting, landing and roving in one mission.





iPhone 12 MAX的效果图泄露


有一篇报告说即将推出的iPhone 12 Pro的外观和缩小版的iPad Pro很像。几天以后,最大版的iPhone 12 Pro,即iPhone 12 Pro Max的CAD设计图泄露了,确认了苹果即将推出的旗舰产品的设计。





The CAD designs come courtesy of the YouTube channel EverythingApplePro and reliable leaker Max Weinbach. Here’s what the CAD designs of the iPhone 12 Pro Max reveal:

YouTube的EverythingApplePro频道上可以免费获得这些CAD图,分享人Max Weinbach也很可靠。以下就是从iPhone 12 Pro Max的CAD设计图上能看到的:

The iPhone 12 Pro Max will be Apple’s largest iPhone ever with a 6.7-inch display.

iPhone 12 Pro Max将会是苹果最大的手机,带有6.7英寸的显示屏。

The design does indeed look like a tiny iPad Pro (or a really big iPhone 5). It features a flat stainless-steel frame as opposed to the rounded frame found on current iPhones.

这个设计的确像缩小版的iPad Pro(或者说是扩大版的iPhone 5)。其特点是有扁平的不锈钢边框,不同于目前苹果手机的圆框。

The bezels on the device will be only 1.55 mm. To put that in perspective, that’s almost 1 mm thinner than the 2.52 mm found on the current iPhone 11 Pro Max.

手机边框只有1.55毫米。说得更明白一点,几乎比现在iPhone 11 Pro Max的2.52毫米的边框薄1毫米。

The overall thickness of the device will be only 7.4 mm, down from the 8.1 mm thickness of the current Pro Max.

手机总厚度只有7.4毫米,比目前8.1毫米厚的Pro Max要薄一点。

The iPhone 12 Pro Max will also come in new colors including light blue, violet, and light orange.

iPhone 12 Pro Max也会出新的颜色,有浅蓝色、紫色和浅橙色。













The London School of Hygiene and Tropical Medicine is working with specially trained dogs to develop a new kind of coronavirus test, one that doesn't require a swab, but just a sniff.


The organization recently discovered canines can detect Malaria infections in humans and they are investigating whether the same is true for COVID-19.


The training began in March and researchers are eyeing six weeks as enough to determine if the dogs are up to snuff.


If the tests go well, these super sniffers could be deployed to screen up to 250 people per hour for the virus.


According to researchers, the dog tests wont replace traditional coronavirus testing but will be used as a supplement since COVID-19 tests are in short supply and results can take hours, if not days to come back.













What were talking about here is something known as a nanolattices - porous structures like the one in the image above thats made up of three-dimensional carbon struts and braces. Due to their unique structure, theyre incredibly strong and lightweight.


Usually these nanolattices are based around a cylindrical framework (theyre called beam-nanolattices). But the team has now created plate-nanolattices, structures based around tiny plates.


This subtle shift may not sound like much, but the researchers say it can make a big difference when it comes to strength.


Based on early experiments and calculations, the plate approach promises a 639 percent increase in strength and a 522 percent increase in rigidity over the beam nanolattice approach.
