Further, combination therapies appear to prevent the emergence of drug resistance. |
| Universal mechanism of regulation in plant cells discovered Posted: 21 Jun 2021 01:05 PM PDT All plant cells obtain their energy mainly from two organelles they contain - chloroplasts (responsible for photosynthesis) and mitochondria (responsible for the biochemical cycle of respiration that converts sugars into energy). However, a large number of a plant cell's genes in its mitochondria and chloroplasts can develop defects, jeopardising their function. Nevertheless, plant cells evolved an amazing tool called the RNA editosome (a large protein complex) to repair these kinds of errors. It can modify defective messenger RNA that result from defective DNA by transforming (deamination) of certain mRNA nucleotides. |

| Projections of US high-tide flooding show rapid increases and extreme months Posted: 21 Jun 2021 09:37 AM PDT In the mid-2030s, multiple United States coastal regions may see rapid increases in the number of high-tide flooding (HTF) days, according to a new study. The combined effects of sea-level rise and natural fluctuations in tidal range are anticipated to cause tipping points in the frequency of HTF. |
| Targeted therapy could be first line treatment for childhood cancer Posted: 21 Jun 2021 09:37 AM PDT Scientists studying a common childhood cancer have made a major breakthrough which could lead to a cure for some youngsters who would not have survived the condition. |
| Adjuvant-free avian influenza vaccines in the works Posted: 21 Jun 2021 09:37 AM PDT Researchers develop a new avian influenza vaccine using plant-based recombinant protein. |
| A tapeworm drug against SARS-CoV-2? Posted: 21 Jun 2021 09:37 AM PDT Researchers have examined the way in which SARS-CoV-2 reprograms the metabolism of the host cell in order to gain an overall advantage. In their study, the researchers were able to identify four substances which inhibit SARS-CoV-2 replication in the host cell. |
| Microscopy deep learning predicts viral infections Posted: 21 Jun 2021 09:37 AM PDT When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluorescence images from live cells, researchers have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage. |
| Nrf2: The custodian regulating oxidative stress and immunity against acrylamide toxicity Posted: 21 Jun 2021 09:37 AM PDT A study using genetically modified mice shows that a protein called Nrf2 increases the expression of protective genes in the acrylamide-induced toxic response. |
| Cellular mechanisms of early mammary gland development unraveled Posted: 21 Jun 2021 09:37 AM PDT A research group used live tissue imaging for the first time to visualize the emergence of the mammary gland. |
| New modeling technique shows greater likelihood, frequency of urban extreme heat events Posted: 21 Jun 2021 09:37 AM PDT This model addresses the fact that most traditional climate models effectively ignore cities entirely, causing them to underestimate the frequency and severity of urban heat waves. Urban areas make up only 2-3% of the earth's land, so their effect on global models is negligible, but more than half of the world's population lives in urban areas, so their impact is significant. |
| Ancient bones provide clues about Kangaroo Island's past and future Posted: 21 Jun 2021 07:42 AM PDT A study of ancient bones on South Australia's Kangaroo Island has provided new information about the Island's past fauna and an insight into how species may live there in the future. |
| Posted: 21 Jun 2021 07:42 AM PDT A research team discovers that silver (Ag)-based antimicrobials can effectively combat antibiotic resistant Staphylococcus aureus by targeting multiple biological pathways via functional disruption of key proteins and can be further exploited to enhance the efficacy of conventional antibiotics as well as to resensitize methicillin-resistant Staphylococcus aureus (MRSA) to antibiotics. |
