Here's how to eat after taking antibiotics, according to science

Gizmag news -

If you've ever taken a course of antibiotics, your infection might have cleared, but your gut might take longer to recover. That's because the disease-fighting pills blast all of the bacteria in your gut, whether they're helpful or not, and it can take time for this community to rebuild itself after completing a course of the medication. This can lead to gastrointestinal distress including diarrhea, gas, and other types of stomach upset. A researcher at the University of Chicago (UChicago) likens the effects of antibiotics to a forest fire in the gut and compares your diet to the way in which the ecosystem develops afterwards.

Digital Photography Review news -

Images: DxO, Ilford, Aperture, SmallRig

Happy Saturday, everyone! We've officially made it to the weekend, which means it's time to take a look at new accessories that came out this week. This week was a quiet one gear-wise, but we saw some new film, software updates, a cage from SmallRig and a 60th anniversary photo book. First, though, let's get into the deals.

Deals of the week Photo: Sony

The Sony a7 IV has earned many recommendations from the DPReview team since its launch. It's been picked as one of the best cameras for street photography, the best video camera for photographers and one of the best affordable cameras for sports. It's even more affordable right now, too, selling for $500 off.

Speaking of the Sony a7 IV, SmallRig released a new modular cage for the hybrid camera this week. It offers full protection on all sides, a genuine leather-wrapped handle and an integrated Arca-Swiss plate. It's currently available for purchase in all regions except for the US, where it won't be available until June 7th.

DxO is celebrating its 30th anniversary this year and unveiled a new logo and tagline to celebrate. It also launched Nik Collection 8 this week. The Nik Collection is a series of seven plugins that work with various programs, but can also function as standalone apps, too. The update brought new masking tools, making it easier to go back and forth between Photoshop and Nik Collection while using masks.

The company also updated Nik Silver Efex, its black-and-white editor, with an updated workflow. You can see all of the updates, download a free trial or update your version at the DxO website.

Stock up on new stock Images: Ilford and Hannah Gross

This week brought a new film stock for analog photographers. Ilford released Kentmere Pan 200, an ISO 200 black-and-white film. The company says it offers fine grain and enhanced contrast for shooting in most situations. It's available in 24 exposures, 36 exposures, 35mm bulk lengths and 120 format.

Finally, something a little different. Aperture, a non-profit photography publisher established in 1952, has released the Sixtieth Anniversary Edition of Edward Weston's The Flame of Recognition. The monograph was initially issued as a hardcover in 1965, though some of the work was included in a 1958 edition of Aperture magazine. It brings together sequences of Weston's images with excerpts from his writing to, in his own words, "present clearly my feeling for life with photographic beauty... without subterfuge or evasion in spirit or technique."

The Flame of Recognition covers the rage of Weston's works, including portraits and nudes, to landscapes and still lifes. It's available for purchase now through Aperture's website.

Ancient humans used sunscreen to survive a deadly magnetic pole shift

Gizmag news -

If you ever travel back in time to hang out with Homo sapiens around 41,000 years ago, pack some sunscreen – or better yet, a tailored outfit, and seek out a cave shelter. New research from the University of Michigan suggests that during a cataclysmic polar reversal, our ancestors might have used these things to survive harmful solar radiation. Meanwhile, Neanderthals didn’t seem to get to grips with these innovations and faded out around the same time.

Given the fact that satellites orbit amongst one another at thousands of miles per hour, it's vitally important to know exactly how fast they're going, in order to avoid collisions. A new device offers an improved way of doing so, and it's appropriately named the Spacecraft Speedometer.

Split-axle survival cart transforms into modern prairie wagon camper

Gizmag news -

From the AntiShanty 4XD, to the Ushi Chuck, to the Trail Mod, to the Jayco Crosstrail, we've seen some unique off-road gear-hauling camper trailers, in the past year and a half alone. And still, some designs leap out from the pack and make us look thrice. The Highcountry Unlimited UTV trailer is just that type of design, a big, old towable tub with two axles, a specialized heavy-duty walking beam suspension, and the ability to transform into the closest thing out there to a covered wagon for the contemporary overland explorer.
