2 . Suddenly screams echo through the forest as alarmed animals warn each other of a predator’s (食肉动物) approach. Lying on my stomach with my camera in front of me, I’ve been watching a nearby stream for hours, waiting. This may be it!
Yes! A 380-pound lioness steps from the trees, heading towards the stream. She crouches (蹲伏) down to drink. She’s only 50 yards away. She stands up and begins to walk towards me, not knowing I’m there. When she’s just about 20 yards away, I move my camera slightly. I don’t want to shock or panic her. She freezes for a moment, then take a crouching position and continues towards me. I’m thinking, “Uh-oh, I’m about to become cat food!” I’ve approached lions before, but now the lion approaches me.
If I stand up and yell, will she leave? Maybe not. If I stand up and run, will she chase me? Probably! So I decided to stay put.
The lioness comes closer. Now she’s only about four yards from me—the closest distance that still allows me to focus my camera lens. Surprisingly, she lies down, posing like a statue in front of me. This makes me feel very small and humble (卑微的). Then she rolls over and looks at me upside down! She seems a little puzzled and appears to be trying to figure me out —Hmm, are you suitable to be eaten? You don’t look dangerous.
Breathe slowly, I remind myself, with my heart beating fast. I carefully back up my tripod (三脚架) just a bit to focus and shoot the picture. Suddenly, she leaps up. In a flash, she runs away, leaving me overwhelmed with emotion.
Getting this photograph took a long time. I spent two years waiting for a permit to track the extremely rare Asiatic lions in the Gir Forest of India and spent three months on foot searching for them. The experience felt like a gift from the forest.

6 . There’s nothing quite like the rush of recognition that comes from seeing a familiar face. Scientists have found it very difficult to explain how we identify well-known faces — or how that process differs from the way we perceive unfamiliar ones.
They have long known that the brain contains a network of areas that respond selectively to faces as opposed to other kinds of objects like feet, cars, smartphones. They also knew that humans process familiar and unfamiliar faces very differently. For example, we excel at recognizing pictures of familiar faces even when they are shot in poor light or at odd angles. But we struggle to recognize even slightly altered images of the same face when it is unfamiliar to us: two pictures of a stranger we’ve never seen before, for instance, shown from different perspectives or in dim light.
Now researchers at The Rockefeller University have begun to unravel the mystery of how the brain recognizes familiar faces. They turned to macaques (猕猴), close evolutionary cousins whose face processing networks are better understood and more easily studied than our own.
Using functional magnetic resonance imaging (磁共振成像), Landi and Freiwald measured the animals’ brain activity as they responded to pictures of other monkeys’ faces. Those faces fell into three categories: personally familiar ones belonging to monkeys that the macaques had lived with for years; visually familiar ones whose pictures they had seen hundreds of times; and totally unfamiliar ones. For comparison’s sake, they also showed the monkeys pictures of personally familiar, visually familiar, and unfamiliar objects.
The researchers expected the macaque face processing network to respond in much the same way to the first two types of faces. But instead, the entire system showed more activity in response to the long-time personally familiar faces. Faces that were only visually familiar, meanwhile, caused a reduction of activity in some areas.
“The whole network somehow distinguishes personally familiar faces from visually familiar faces,” says Landi.
Even more surprisingly, the faces of animals whom the macaques had known for years caused the activation of two previously unknown face-selective areas.
One is located in a region of the brain associated with so-called declarative memory, which consists of facts and events that can be consciously recalled. The other area lies in a region associated with social knowledge, such as information about individuals and their position within a social class — “a specific form of memory,” Freiwald says, “that is highly developed in primates (灵长类动物), and certainly in humans.”

There’s a longstanding debate on how to reduce emissions in the trucking industry. Germany is testing out a new system — eHighways, which feed electricity to trucks while they drive.
Figuring out how to reduce emissions in the commercial trucking industry is key to the fight against climate change. Because long-haul diesel(柴油机) trucks spend so much time on the road, they disproportionately produce pollutants, greenhouse gases, and contribute to dirty air.
Germany is at the forefront of this fight against truck emissions.
Using wires strung above the highway and a pantograph (current collector) mounted to the top of a truck, Germany’s e Highways use technology similar to that of an electric city bus. The system delivers power directly from the electrical line straight to the truck’s motor.
Adapting the same equipment that is used for driving trains and urban street cars, Siemens, the German electricity company, provided the equipment for the test route — stringing miles of high-voltage electrical cable above the Autobahn.
The eHighway system saves truckers weight and money compared to outfitting trucks with electric batteries — which could be both heavy and expensive. Using overhead wires on the freeway, a truck would only need a big enough battery to drive the short distance from the offramp to its destination. Not to mention, the money trucking companies would save on fuel, their largest cost.
While this system saves money in the long term, stringing thousands of miles of electrical cable above freeways would be costly to German taxpayers. Is it feasible? For now, Germany is just testing it out. The eHighway system has also been tested in Sweden and a 1-mile stretch near Long Beach, California.
It would take 2,500 miles of electrical wiring to accommodate about 60% of German truck traffic. So far, only a couple 3-mile-stretches of highway outside Frankfurt, Schleswig-Holstein, and Baden-Württemberg are equipped with overhead electrical cables. By the end of the year, more than 20 trucks carrying real loads will be using the system. The companies funding the project want to see how the eHighway stretch performs in everyday use.
Building the overhead cables would cost the German government about $5 million dollars per mile. Germany’s Ministry of Environment will compare the results of this project with studies of trucks using electric batteries and hydrogen fuel cells. Based on the data, the ministry plans to decide in three to four years which eco-friendly technology to invest in and support.
“Numerous studies have come to the conclusion that overhead cable trucks, despite the high infrastructure costs, are the most cost-effective option,” the Ministry of Environment said to The New York Times.
No matter which option the ministry chooses, the goal is to create a more environment-friendly future for the commercial trucking industry.
