In a new study, Stanford researchers report that intensifying precipitation contributed one-third of the financial costs of flooding in the United States over the past three decades, totaling almost $75 billion of the estimated $199 billion in flood damages from … Read More

‘Galaxy-sized’ observatory sees potential hints of gravitational waves — ScienceDaily

|

Scientists have used a “galaxy-sized” space observatory to find possible hints of a unique signal from gravitational waves, or the powerful ripples that course through the universe and warp the fabric of space and time itself. The new findings, which … Read More

Measurements of pulsar acceleration reveal Milky Way’s dark side — ScienceDaily

|

It is well known that the expansion of the universe is accelerating due to a mysterious dark energy. Within galaxies, stars also experience an acceleration, though this is due to some combination of dark matter and the stellar density. In … Read More

ALMA captures distant colliding galaxy dying out as it loses the ability to form stars — ScienceDaily

|

Galaxies begin to “die” when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away galaxy. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) … Read More

Unravelling the mystery that makes viruses infectious — ScienceDaily

|

Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus ‘package up’ their genetic code, allowing them to infect cells. The findings, published today (Friday, 8 January) in the journal PLOS Pathogens … Read More

Why crocodiles have changed so little since the age of the dinosaurs — ScienceDaily

|

New research by scientists at the University of Bristol explains how a ‘stop-start’ pattern of evolution, governed by environmental change, could explain why crocodiles have changed so little since the age of the dinosaurs. Crocodiles today look very similar to … Read More

How Earth’s oddest mammal got to be so bizarre — ScienceDaily

|

Often considered the world’s oddest mammal, Australia’s beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes. Now, … Read More

Primordial black holes and the search for dark matter from the multiverse — ScienceDaily

|

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study … Read More

Newly described chemical reaction could have assembled DNA building blocks before life forms and their enzymes existed — ScienceDaily

|

Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our planet. In a study published in the chemistry journal Angewandte Chemie, they demonstrated that a simple compound called diamidophosphate (DAP), … Read More

Dual-acting immuno-antibiotics block an essential pathway in bacteria and activate the adaptive immune response — ScienceDaily

|

Wistar Institute scientists have discovered a new class of compounds that uniquely combine direct antibiotic killing of pan drug-resistant bacterial pathogens with a simultaneous rapid immune response for combatting antimicrobial resistance (AMR). These finding were published today in Nature. The … Read More

Study suggests our brains may be more in tune with each other than we think — ScienceDaily

|

As COVID cases rise, physically distancing yourself from other people has never been more important. Now a new UCLA study reveals how your brain navigates places and monitors someone else in the same location. Published Dec. 23 in Nature, the … Read More

Preliminary results suggest anti-COVID19 nanobodies may be effective at preventing and diagnosing infections — ScienceDaily

|

National Institutes of Health researchers have isolated a set of promising, tiny antibodies, or “nanobodies,” against SARS-CoV-2 that were produced by a llama named Cormac. Preliminary results published in Scientific Reports suggest that at least one of these nanobodies, called … Read More
