Study uncovering multiple new, unusual bacterial immune defense mechanisms...
Until a decade ago, scientists were not aware that bacteria had complex immune systems - ones that could keep up with the pace of evolution in viruses called phages that infect bacteria. That changed...
View ArticleResearchers identify 'social place cells' in the brain that respond to the...
Whether we're playing a team sport or just strolling with our family through the park, we're continually aware of the positions of those around us - and where each is heading. Scientists have, in...
View ArticleGenetic barcodes are used to quantify crucial populations in a coral reef...
Almost all the wildly varied, colorful fish that populate coral reefs start life as tiny, colorless, tadpole-like larvae. Telling one from the other is nearly impossible - even for experts - and this...
View ArticleMini brains may wrinkle and fold just like ours
Flat brains growing on microscope slides may have revealed a new wrinkle in the story of how the brain folds.
View ArticleHow malaria tricks the immune system
Global efforts to eradicate malaria are crucially dependent on scientists' ability to outsmart the malaria parasite. And Plasmodium falciparum is notoriously clever: It is quick to develop resistance...
View ArticleOdors that carry social cues seem to affect volunteers on the autism spectrum...
Autism typically involves the inability to read social cues. We most often associate this with visual difficulty in interpreting facial expression, but new research at the Weizmann Institute of Science...
View ArticleOff track: How storms will veer in a warmer world
Under global climate change, the Earth's climatic zones will shift toward the poles. This is not just a future prediction; it is a trend that has already been observed in the past decades. The dry,...
View ArticleJuno probe discovers surprising activity in Jupiter's interior
NASA's Juno spacecraft has plumbed the depths of Jupiter, revealing that the planet's famous bands of swirling winds extend thousands of kilometres down. The work is the sharpest glimpse yet into...
View ArticleFaster metabolism makeover—nurturing your gut bacteria
Here's how to take control of your cravings and lose weight for good by improving your gut health.
View ArticlePrinciples for computational design of binding antibodies
The idea of proteins that can be designed on computers for specific functions has been a cutting-edge concept that has stubbornly remained "in the future." New research at the Weizmann Institute of...
View ArticleAn original method of cooling ions could have new and interesting uses
When investigating atoms, scientists face a challenge: At room temperature, individual atoms in a gas have kinetic energy, and fly around at large velocities. Temperature is, in essence, the relative...
View ArticleGenomic recycling: Ancestral genes take on new roles
One often hears about the multitude of genes we have in common with chimps, birds or other living creatures, but such comparisons are sometimes misleading. The shared percentage usually refers only to...
View ArticleAltitude training for cancer-fighting cells
Mountain climbers and endurance athletes are not the only ones to benefit from altitude training - that is, learning to perform well under low-oxygen conditions. It turns out that cancer-fighting cells...
View ArticleScientists find bacteria in pancreatic tumors that metabolize a common drug
To the reasons that chemotherapy sometimes does not work, we can now add one more: bacteria. In a study published today in Science, researchers describe findings that certain bacteria can be found...
View ArticleEat a purple potato if you know what's good for you
Israeli scientists synthesize healthier potatoes and tomatoes in brilliant colors. The technology can also produce unusually hued ornamental flowers.
View ArticleIsraeli gene-crunching firm aims to cut data down to size
The human genome has been mapped, but the genomes of most humans have not – at least not yet. When individual genomes are mapped, the world will have a problem: there is simply not enough space in the...
View ArticleWhat happens at the moving edge of a crack?
It is said that a weak link determines the strength of the entire chain. Likewise, defects or small cracks in a solid material may ultimately determine the strength of that material – how well it will...
View ArticleSelf-assembling protein complexes could provide scaffolding for nanostructures
When hemoglobin undergoes just one mutation, these protein complexes stick to one another, stacking like Lego blocks to form long, stiff filaments. These filaments, in turn, elongate the red blood...
View ArticleThe unexpected role of a well-known gene in creating blood
One of the first organ systems to form and function in the embryo is the cardiovascular system: in fact, this developmental process starts so early that scientists still have many unresolved questions...
View ArticleThe lining of our intestines uses an approach known to business to quickly...
Every time we swallow food, cells that line the intestines must step up their activity in a sudden and dramatic manner. According to a new study by Weizmann Institute of Science researchers, reported...
