2023/6/19
No two hearts beat alike. The size and shape of the the heart can vary from one person to the next. These differences can be particularly pronounced for people living with heart disease, as their hear...
Near-atomic look at three ways to thwart SARS-CoV-2 variants
SARS-CoV-2 virus COVID-19 micro molecule protein
2021/8/6
A structural analysis of llama-derived nanobodies interacting with SARS-CoV-2 describes three mechanisms the microscopic molecules use to disarm the virus and its variants, pointing to new therapeutic...
A Cornell-led collaboration has been awarded a five-year, $3.6 million grant from the National Institutes of Health to explore the ways that the gut microbiome – that mass of microorganisms inside us ...

2021/4/9
Scientists have examined the immune system of an unusual group of mammals, which includes a small South American opossum, to find solutions that evolution has produced to fight disease-causing pathoge...
Tree rings and Iceland's Laki volcano eruption:A closer look at climate（图）
Tree rings Iceland Laki volcano eruption A closer look climate
2021/2/5
By reading between the lines of tree rings, U.S. National Science Foundation-funded researchers at the University of Arizona reconstructed what happened in Alaska the year the Laki Volc...
New study takes comprehensive look at marine pollution and human health（图）
marine pollution human health
2020/12/11
For centuries, the oceans have been viewed as an inexhaustible receptacle for the byproducts of human activity. Today, marine pollution is widespread and getting worse and, in most countries, poorly c...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The results are...

Researchers offer look central engine powering solar flare
2020/7/31
In a U.S. National Science Foundation-funded study published in Nature Astronomy, an international team of researchers has presented a new, detailed look inside the "central engine" of a lar...
Earliest look at newborns' visual cortex shows that babies are hard-wired to see faces and places（图）
Earliest newborns visual cortex shows babies hard-wired faces and places
2020/3/13
Within hours of birth, a baby's gaze is drawn to faces. Now, brain scans of newborns reveal the neurobiology underlying this behavior; in babies as young as 6 days, brains appear to be hardwired for t...

Researchers road aid self-driving cars
2020/3/6
Car companies and researchers have been feverishly working to improve the technologies behind self-driving cars. But so far, even the most high-tech vehicles still fail when it comes to safely navigat...
Another Look at Key Randomisation Hypotheses
linear cryptanalysis key randomisation hypotheses
2019/8/26
In the context of linear cryptanalysis of block ciphers, let p0p0 (resp. p1p1) be the probability that a particular linear approximation holds for the right (resp. a wrong) key choice. The standard ri...
Another look at some isogeny hardness assumptions
post-quantum cryptography isogeny-based cryptography cryptanalysis
2019/8/22
The security proofs for isogeny-based undeniable signature schemes have been based primarily on two isogeny hardness assumptions: that the One-Sided Modified SSCDH problem and the One-More SSCDH probl...
Another Look at Byzantine Fault Tolerance
cryptographic protocols Byzantine Fault Tolerance
2019/7/26
We review several solutions for the Byzantine Fault Tolerance (BFT) problem and discuss some aspects that are frequently overlooked by existing literatures. For example, PBFT and HotStuff BFT protocol...
