Israeli scientists have discovered that the SIRT6 protein may extend human life

Israeli scientists have extended the lifespan of laboratory mice by 23 percent with a special protein in a new study that could lay the groundwork for humans to live to 120 years, foreign media reported. Israeli scientists reportedly increased the supply of SIRT6 protein in 250 mice, increasing the life expectancy of subjects by not only 23 percent, but also younger and less susceptible to cancer than the average mouse. SIRT6 proteins “control the rate of aging” but usually decrease…

The number of ticks is likely to soar in most parts of the United States

The number of ticks is likely to soar in most parts of the United States

According to different experts, ticks, a nasty little parasite attached to humans and animals, could be a bigger problem this summer than last year, foreign media Slash Gear reported. Much of the United States has experienced weather that has led to a surge in tick populations, especially in the Midwest states, where tick activity is above average. Ticks are common throughout the United States, but their level of activity each summer depends on the climate: if the winter is mild,…

Noninvasive fluorescence microscopy (DOLI) can provide deep imaging of the brain

Noninvasive fluorescence microscopy (DOLI) can provide deep imaging of the brain

Researchers from the University of Zurich and the Technical University of Zurich in Switzerland have developed a new technique called Diffuse Optical Positioning Imaging (DOLI), which uses it to observe microvascular vessels deep in the brains of living mice at high resolution and without invasiveness. The technology has excellent resolution, can see deep tissue, provides a powerful optical tool for observing brain function, and has broad application prospects in the study of neural activity, microcirculation, neurovascular coupling, and neurodegeneration. The…

Cancer treatment may accelerate cell aging

Cancer treatment may accelerate cell aging

New research suggests that some anti-cancer treatments may accelerate cell aging, and changes in patients’ DNA may lead to greater inflammation and fatigue. The findings were published online by Wiley in cancer, a peer-reviewed journal of the American Cancer Society. Gene activity is often adjusted in life through epigenetic changes or physical modification of DNA but does not involve altering the underlying DNA sequence. Some people may experience epigenetic age acceleration (EAA), putting them at higher risk of age-related diseases…

Scientists have found new ways to stop children from contracting respiratory viruses

Scientists have found new ways to stop children from contracting respiratory viruses

Antiviral peptides (AVPs) consist of three spirals (green) that lock around the virus’s fusion protein (orange) to prevent the virus from entering the cell. Gelman Labs adds unique β amino acids to peptides (purple), which do not interfere with this critical interaction and make peptides more stable. By designing a small protein or peptide that prevents human para-flu viruses from attaching to cells, researchers have improved a method in rodent models designed to help keep children healthy. Human para-flu viruses,…

MagicDNA software helps design more complex DNA robots

MagicDNA software helps design more complex DNA robots

Researchers at Ohio State University have announced the development of new software called MagicDNA. The software is a new development tool that allows scientists to design more complex DNA robots and nano-devices than ever before. The software allows researchers to design ways to combine very small DNA strands into complex structures with components such as rotors and hinges that can be moved to accomplish a variety of tasks. Devices created with the software can perform tasks such as drug delivery…

The latest breakthrough in human monkey hybrid embryos

The latest breakthrough in human monkey hybrid embryos

In 2019, a team led by Spanish scientist Juan Carlos Izpisua successfully bred the world’s first “human monkey hybrid embryo” by injecting human stem cells into monkey embryos using advanced technology. The scheme sparked heated debate at the time and was suspended when the embryo was 14 days old. Now, the “human monkey hybrid embryo” ushered in the latest breakthrough. In a new report published April 15 in the journal Cell, the researchers note that based on previous studies, human…

A new discovery has upended cancer metabolism models over the past century

A new discovery has upended cancer metabolism models over the past century

Tumor cells used to be thought to metabolize at high rates of glucose consumption, but a new finding, published Wednesday in the journal Nature by researchers at Vanderbilt University in the United States suggests that tumor cells themselves are not the culprits, but rather that immune cells (non-tumor cells) called macrophages have higher glucose intake levels. The discovery that different cells in the tumor microlenses use different nutrients, according to their metabolic procedures has upended cancer metabolism models over the…

Neuroscientistes reveal why the brain loves music

Neuroscientistes reveal why the brain loves music

According to a new study published in JNeurosci, communication between the brain’s auditory and reward circuits is what humans find valuable to music. Although there are no obvious biological benefits, humans still like music. Neuroimaging studies have highlighted the similarities between the brain’s reward circuits when dealing with music and other rewards such as food, money, and alcohol. But neuroimaging research is inherently interrelated. Now, in a new study, researchers are trying to determine the causal effects of this circuit…

The number of neurons in the human brain is three times that of chimpanzees and gorillas

The number of neurons in the human brain is three times that of chimpanzees and gorillas

The number of neurons in the human brain is three times that of chimpanzees and gorilla brains! Why is the human brain bigger than the brains of other apes? Writing in the latest issue of Cell, British scientists say they have discovered for the first time, why the human brain is getting bigger — a key molecular switch, ZEB2, or play a key role in it. In the latest study, a team led by Madeleine Lancaster of the MRC Laboratory…
