This advancement represents a potentially important step toward 'personalized' or 'precision' medicine, a relatively new discipline that tailors dietary advice and disease treatment to an individual's own genome sequence. |
| Hidden genes may be tapped for new antibiotics Posted: 11 Jul 2022 10:53 AM PDT Bioscientists learn to trigger 'silent' gene clusters in bacteria that could be rich sources of new antibiotic candidates. |
| Abnormal heart metabolism may predict future sudden cardiac death Posted: 11 Jul 2022 10:53 AM PDT Adults with abnormal heart metabolism are up to three times more likely to experience life-threatening arrhythmias (an irregular heart rhythm), and MRI techniques could be used to detect the condition and predict future sudden cardiac death (SCD), according to a small, but rigorous study. |
| Video game players show enhanced brain activity, decision-making skill study Posted: 11 Jul 2022 10:53 AM PDT Frequent players of video games show superior sensorimotor decision-making skills and enhanced activity in key regions of the brain as compared to non-players, according to a recent study. |
| Hopping space dust makes asteroids look rougher Posted: 11 Jul 2022 10:50 AM PDT When NASA's OSIRIS-REx spacecraft arrived at the asteroid Bennu, scientists discovered something surprising: The asteroid's surface wasn't smooth like many were expecting but was covered in large boulders. Now, a team of physicists think they know why. |
| Preterm birth more likely with exposure to phthalates Posted: 11 Jul 2022 08:18 AM PDT Pregnant women who were exposed to multiple phthalates during pregnancy had an increased risk of preterm birth, according to new research. Phthalates are chemicals used in personal care products, such as cosmetics, as well as in solvents, detergents, and food packaging. |
| Bomb detectors picking up more blue whale songs in Indian Ocean Posted: 11 Jul 2022 08:18 AM PDT The good news is, pygmy blue whales appear to be thriving in the Indian Ocean. But not-so-good is that climate change may be threatening their food sources. |
| Stronger overturning circulation in the Pacific during the last glacial period Posted: 11 Jul 2022 08:18 AM PDT Coral data indicate that the upper layers of Pacific Ocean were more mixed during the last Ice Age than they are today. New research shows that the Tasman Sea in the South Pacific was an important component of the global conveyor belt at that time. |
| Paleobiology: Complex family relationships Posted: 11 Jul 2022 08:18 AM PDT An international team of researchers has managed to classify fossils of one of the most species-rich fish groups into a family tree for the first time. |
| Programmed cell death in cancer cells: Overcoming resistance through paraptosis-inducing compounds Posted: 11 Jul 2022 08:18 AM PDT Inducing programmed cell death (PCD), such as apoptosis, is a widely used therapeutic option for the treatment of cancer. Unfortunately, many cancer cells become resistant to PCDs, and continue multiplying. In a new study, researchers have synthesized new complex-hybrid compounds named triptycene-peptide hybrids (TPHs), which successfully induced a kind of PCD known as paraptosis in Jurkat cells - -a type of lymphocytes. These paraptosis-inducing compounds may revolutionize cancer therapy in the future. |

| Pocket gophers are underground root 'farmers' Posted: 11 Jul 2022 08:18 AM PDT Pocket gophers are known for living solitary, underground lives, eating roots in North and Central American grasslands. Now, researchers have found that pocket gophers keep up with the high energy demands of their burrowing lifestyle by 'farming' roots that grow into their tunnels. They calculate that these roots supply 20 to 60 percent of the gophers' need for daily calories. |
| Friends enjoy being reached out to more than we think Posted: 11 Jul 2022 06:52 AM PDT People consistently underestimate how much others in their social circle might appreciate an unexpected phone call, text or email just to say hello, and the more surprising the connection, the greater the appreciation, according to new research. |
| Nanoparticles can save historic buildings Posted: 11 Jul 2022 06:51 AM PDT Buildings made of porous rock can weather over the years. Now scientists have studied in detail how silicate nanoparticles can help save them. Many historical buildings were built of sandstone. It is easy to work with, but does not withstand weathering well. It consists of sand grains that are relatively weakly bonded to each other. However, it is possible to increase the resistance of the stone by treating it with special silicate nanoparticles. |
| Heart-healthy, lower sodium version of traditional Chinese cuisine lowered blood pressure Posted: 11 Jul 2022 06:51 AM PDT Researchers have created a heart-healthy, lower sodium version of traditional Chinese cuisine that was appetizing, affordable and significantly lowered blood pressure among adults diagnosed with hypertension. The heart-healthy Chinese diet reduced sodium intake in half, from nearly 6,000 mg daily to about 3,000 mg daily, and featured reduced fat, increased protein and carbohydrates, twice as much dietary fiber and increased potassium. People with high blood pressure may benefit from adopting a similar heart-healthy, lower sodium diet. |
| Education system 'neglecting the importance of plants' Posted: 11 Jul 2022 06:51 AM PDT People are becoming 'disconnected from the botanical world' at a time when plants could help solve global environmental problems, warn a group of research scientists. They say the problem has been exacerbated by schools and universities reducing their teaching of basic plant science, including plant identification and ecology. They describe a self-accelerating cycle which risks '...the extinction of botanical education,' where biology is taught predominantly by people with research interests in animal science. |
| Adding salt to your food at the table is linked to higher risk of premature death Posted: 10 Jul 2022 03:59 PM PDT People who add extra salt to their food at the table are at higher risk of dying prematurely from any cause, according to a study of more than 500,000 people. |
| Posted: 08 Jul 2022 09:36 AM PDT Scientists revealed new research based on a cache of fossils that contains the brain and nervous system of a half-billion-year-old marine predator from the Burgess Shale called Stanleycaris. Stanleycaris belonged to an ancient, extinct offshoot of the arthropod evolutionary tree called Radiodonta, distantly related to modern insects and spiders. These findings shed light on the evolution of the arthropod brain, vision, and head structure. |
