As scientists detect plant fluorescence in better detail, they inch closer to helping farmers respond to extreme weather and close in on understanding how carbon cycles through ecosystems.

The colossus iceberg that split from Antarctica’s Larsen C ice shelf on 12 July 2017 is now in the open waters of the South Atlantic near the South Orkney Islands, about 1050 km from its birthplace.

New research has identified the specific brain cells that control how much sugar you eat and how much you crave sweet tasting food

New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.

Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital Basel has now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.

In February 2020, a Covid-19 patient cohort was established at the University and the University Hospital in Basel to prospectively monitor a range of diagnostic means and potential treatments for Covid-19, including the off-label use of hydroxychloroquine and lopinavir/ritonavir.

A research group monitored lopinavir plasma levels in Covid-19 patients. “Considering that substantial inflammation was observed in these patients, and previous studies have shown the inhibition of drug metabolism by systemic inflammation, we had the rationale to investigate the effect of inflammation on lopinavir and hydroxychloroquine plasma levels,” states Professor Catia Marzolini, first author of the study and professor for experimental medicine at the University of Basel.

A Montana State University professor’s research on plant chemistry in the Northern Great Plains and Northern Rockies has been published in Global Change Biology, a prominent journal that promotes exploration of the connections between biological processes and environmental change.

NASA used satellite data to create an animation of Fay’s development and progression over the past few days, showing how the storm organized into a tropical storm.

Biologists from the University of Bayreuth have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish.

NASA’s Aqua satellite revealed better organization and colder cloud top temperatures in Tropical Storm Cristina, indications that the storm was strengthening.

On July 10 at 4:35 a.m. EDT (0835 UTC), the MODIS instrument aboard NASA’s Aqua satellite analyzed Tropical Storm Cristina’s cloud tops in infrared light. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite found that the most powerful thunderstorms were east and south of the center of circulation, where temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 Celsius). These cloud top temperatures had become colder than they were over the previous day. Cloud top temperatures that cold indicate strong storms with the potential to generate heavy rainfall.
