Scientist uncovers roots of antibiotic resistance
Bacteria naturally adapt to various environmental stimuli and as they mutate, these changes can make them resistant to drugs that would kill or slow their growth......»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
"Not the end of the world", says data scientist on the big issues
Humanity has made great strides in recent decades: air is cleaner; poverty, deforestation and childhood mortality have fallen; gasoline cars—and maybe coal—are on the way out......»»
Researchers reveal how plants protect themselves from viral infection by regulating deacetylation
In a paper published in Science Bulletin, a team of Chinese scientists demonstrated that TaSRT2 recognized viral protein P153 and induced wheat resistance to CWMV through inhibition of the TaSRT2-mediated deacetylation of H3K9ac and H3K79ac, which ev.....»»
Pear-derived discovery: A genetic mechanism to fortify crops against drought
A recent study has shed light on a critical genetic mechanism that boosts plants' ability to withstand drought. The research uncovers the role of the transcription factor PbERF3, native to wild pears, which works in concert with the protein PbHsfC1a.....»»
Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors" reproduction ability
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought......»»
Climate scientist suggests fast escalation of megastorms like Beryl

Inverse design method improves high-temperature performance of carbide coatings
The hot-end components of high-performance high-speed aircraft need to meet performance requirements such as long service life, wide temperature range oxidation resistance and ablation resistance. This puts forward higher requirements for high-temper.....»»
Fossil places extinct saber-toothed cat on Texas coast
Important scientific finds don't always come in the biggest, buzziest packages. Sometimes new discoveries come in little ugly rocks. Such is the case of a 6-centimeter-wide, nondescript mass of bone and teeth that helped a scientist at The University.....»»
Antibiotic pollution disrupts the gut microbiome and blocks memory in aquatic snails, study finds
Antibiotics prevent snails from forming new memories by disrupting their gut microbiome—the community of beneficial bacteria found in their guts......»»

New study unveils how water dynamics slow down at low temperatures
A scientist at the Institute for Molecular Science has published a study that provides insight into the puzzling phenomenon of dynamic slowdown in supercooled water, an essential step toward understanding the glass transition in liquids......»»
Study shows plant hydraulics create streaming electric potential in sync with biological clock
When plants draw water from their roots to nourish their stems and leaves, they produce an electric potential that could be harnessed as a renewable energy source. However, like all living things, plants are subject to a circadian rhythm—the biolog.....»»
New molecule found to suppress bacterial antibiotic resistance evolution
Researchers from the University of Oxford have developed a new small molecule that can suppress the evolution of antibiotic resistance in bacteria and make resistant bacteria more susceptible to antibiotics. The paper, "Development of an inhibitor of.....»»
Personalized phage therapy heals resistant wounds in Siamese cat
A new study has shown an advance in the treatment of antibiotic-resistant infections in animals. The research, focusing on a 5-year-old Siamese cat Squeaks with a multidrug-resistant Pseudomonas aeruginosa infection post-arthrodesis surgery, marks th.....»»
“Deny, denounce, delay”: The battle over the risk of ultra-processed foods
Big Food is trying to dampen fears about the effects of industrially formulated substances. Enlarge (credit: monticelllo/Getty) When the Brazilian nutritional scientist Carlos Monteiro coined the term “ultra-processed.....»»

On repeat: Biologists observe recurring evolutionary changes, over time, in stick insects
A long-standing debate among evolutionary scientists goes something like this: Does evolution happen in a predictable pattern or does it depend on chance events and contingency? That is, if you could turn back the clock, as celebrated scientist Steph.....»»
Desert locusts" jaws sharpen themselves, materials scientist discovers
Sharks lose teeth all their lives, replacing them in a kind of endless rotating Rolodex, while humans, of course, get only our two sets. Beavers' teeth, notoriously, grow all their lives and have to be worn down to prevent injury......»»
