What is the hardest thing you think scientists need to do in a lab? Organic chemistry may not be the first thing that comes to mind, but multi-step organic syntheses are easily ranked a top challenge, even among experienced chemists. Nevertheless, computer scientists surprised us again with artificial intelligence (AI) which, despite having less chemistry experience than the average high-schooler, could prescribe recipes with success. … Continue reading AI advises chemists on how to make complex molecules
Since the first exoplanet discovery in the 1990s, scientists have learned of the diverse and abundant nature of exoplanets, having now found more than 3700. With such a large and disparate sample set, ESA (European Space Agency) has set its sights on learning how these planets form and what their chemistry is like. A new telescope, or ‘mission’, ARIEL (Atmospheric Remote-sensing Infrared Exoplanet Large-survey), has … Continue reading ARIEL: Exploring strange new worlds and boldly observing what no telescope has observed before.
In order to feed every human being on the planet by 2050, the world will need to produce far more food. One difficulty farmers face is finding enough fresh water. A group of scientists led by Katarzyna Glowacka, from the University of Illinois, Urbana, may have found a potential way to save farmers water. The group’s technique hinges on the stomata of plants. Stomata are … Continue reading Thirsty Plants: Can plants be genetically modified to need less water?
It’s very easy to disparage fat and fat cells, especially in our weight-conscious culture. However, fat cells might deserve more credit than we give them. Fat cells can help store energy and provide our bodies with insulation. And now, research from Paul Martin’s group at the University of Bristol has shown that fat cells can move around within body compartments to help heal wounds. Researchers … Continue reading Fat cells – Nature’s Band-Aid?
by Jenny Zheng figures by Rebecca Clements With winter soon coming to an end (hopefully), many of us have been plagued by seemingly endless hacking that’s accompanied by phlegm, a type of mucus produced by the respiratory tract. The body starts feeling better after a week of sickness, but even after that “hell-week,” one final foe has to be dealt with: the phlegm. It’s such … Continue reading All About That Mucus: How it keeps us healthy
We cannot predict how long we each live, but can our genes? For as long as longevity has been a desirable good, it has never been equally distributed across humanity, not even within families. The role of heritable traits in longevity is still debated. Previous genomic studies have reported a low heritability for longevity. However, inadequate sample sizes prevent these studies from examining the influence of … Continue reading Crowdsourced Data Helps Scientists Construct the World’s Largest Family Tree
by Sasha Brownsberger figures by Abagail Burrus Everything you have ever touched, seen, or tasted; the air you breathe; the ground on which you stand; and the constituents of your body all consist of a type of matter that is only a fraction of all that is. In light of a series of unexpected discoveries over the past half century, astronomers and physicists have determined … Continue reading Seeing the Invisible: A short history of the scientific evidence of dark matter
