Now,Jah is a professor at The University of Texas at Austin and a space environmentalist.As a
space environmentalist and scientist,Jah is working on solutions to the junk in the skies-a problem
growing more quickly than ever since the late 1990s,with the development in commercial space
exploration launching rockets more often than ever.In 2022,he mapped the human-made objects in
Earth's orbit()and helped launch a satellite and space junk tracker application available to the
public.
About 170 million space pieces are in Earth's orbit,around 35,000 of which are large enough to be
tracked.
"The best solution unfortunately is to transport it to the earth and have it burn up in the
atmosphere,"Jah highlights,but it pollutes the atmosphere in the process.
Despite working in the eye of a growing problem in the skies,Jah is optimistic about the way
forward.“Mother Nature is very resilient(有弾性的).We can see evidence of that,”he says..

Crows are known to be very clever birds.Now a new study showed that they can count out loud
and they may even have the same number recognizing skills as human babies.
Researchers found that crows can produce a specific number of caws()in response to visual
or auditory stimuli(视觉和听觉刺激)，enabling them to count out loud between one and four.The
discovery is the first time that animals have been shown to count by making a number of vocalizations
(发声).
"Producing a specific number of vocalizations with purpose requires a combination of number
recognizing abilities and voice control,"the researchers wrote in the study."Our results show that crows
can flexibly produce a number of vocalizations on purpose.
Many studies have shown that animals,including honeybees,lions,frogs and ants,have a number
sense.Yet none of these provide enough evidence that animals share humans'ability to count out loud.
In the new study,the researchers presented three crows with visual and auditory stimuli.The visual
stimuli is numbers and the auditory stimuli is the sounds of different instruments.
After the training,the birds learned that each stimuli represents a set number of caws between one
and four.After cawing four times for a sound or symbol associated with four caws,for example,the
birds were trained to touch the screen with their mouth displaying them to signal they had finished.If the
crows gave the right number of caws,they were rewarded with a treat.Once they were trained,the
