Study reveals type 2 diabetes diagnosis spurs cholesterol shifts, alters Ccardiovascular risk

A recent study published in the journal Scientific Reports assessed the associations between the change in total cholesterol (TC) levels after type 2 diabetes (T2D) diagnosis (relative to pre-diagnosis levels) and the risk of cardiovascular disease (CVD).

CVD is the global leading cause of mortality. T2D is a gateway disease to CVD. A study revealed higher coronary heart disease (CHD) and stroke risks in diabetes patients than in non-diabetic individuals. The global prevalence of T2D is expected to exceed 10% by 2030. Therefore, preventing CVD in people with diabetes could be of public health significance.

Hypercholesterolemia is a significant risk factor for CVD, and its adverse effects on CVD could be more evident in individuals with metabolic conditions, e.g., T2D. Diabetes patients may be more susceptible to hypercholesterolemia’s negative impact on CVD risk. Nonetheless, T2D diagnosis often results in positive lifestyle changes helping reduce hypercholesterolemia or CVD risk.

Researchers discover Chinmo, ‘the youth gene’

A new study published on eLife and led by the Institute for Evolutionary Biology (IBE, CSIC-UPF) and the IRB Barcelona, has revealed that the Chinmo gene is responsible for establishing the juvenile stage in insects. It also confirms that the Br-C and E93 genes play a regulatory role in insect maturity. These genes, which are also present in humans, act as a promoter and as a suppressor, respectively, of cancerous processes.

The results of the research, which was carried out with the fruit fly Drosophila melanogaster and the cockroach Blatella germanica, reveal that these genes have been conserved throughout the evolution of insects. Therefore, it is believed that they could play a key role in the evolution of .

Insects that undergo complete metamorphosis, such as flies, go through the following three stages of development: the embryo, which is formed inside the egg; the larva (juvenile stage), which grows in several phases; and the pupa, which is the stage that encompasses metamorphosis and the formation of the adult organism.

Graphene sensor could let you control robots with your mind

Australian researchers have used the “wonder material” graphene to develop a sensor that could enable anyone to control robot technology with their minds.

“The hands-free, voice-free technology works outside laboratory settings, anytime, anywhere,” said co-developer Francesca Iacopi. “It makes interfaces such as consoles, keyboards, touchscreens, and hand-gesture recognition redundant.”

The challenge: Brain-computer interfaces (BCIs) are systems that translate brain activity into commands for machines, usually for medical reasons. A person with a limb amputation can use one to control a prosthetic with their mind, while someone with paralysis could use a BCI to “type” words on a computer screen just by thinking about them.

Elon Musk’s brain implant company Neuralink approved for in-human study

😗😁

Neuralink, Elon Musk’s brain-implant company, said on Thursday it had received a green light from the US Food and Drug Administration (FDA) to kickstart its first in-human clinical study, a critical milestone after earlier struggles to gain approval.

Musk has predicted on at least four occasions since 2019 that his medical device company would begin human trials for a brain implant to treat severe conditions such as paralysis and blindness.

China faces new Covid wave from XBB variant that could peak at 65 million cases a week

So it is confirmed that the new variant of covid 19 virus is here but the actual spike now is in China. But will most likely spread globally much how previous viruses have done. Be sure to be prepared for another pandemic. Anyway what may be the possible cure would be new bioengineering techniques with crispr to eventually be immune to the virus like I have posted in some genetically engineered cells recently were made. But rest assured this could lead to a global pandemic because the current variant is taxing our current vaccination measures.

The country once had some of the harshest Covid restrictions on the planet, but the response from the government and the public is relatively muted this time.

Quantum scientists accurately measure power levels 1 trillion times lower than usual

😗😁

Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures—a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.

Quantum science takes place mostly at using devices called dilution refrigerators. The experiments also have to be done at tiny energy levels—down to the energy level of single photons or even less. Researchers have to measure these extremely low energy levels as accurately as possible, which means also accounting for heat—a persistent problem for .

To measure heat in quantum experiments, scientists use a special type of thermometer called a bolometer. An exceptionally accurate bolometer was recently developed at Aalto University by a team led by Mikko Möttönen, associate professor of quantum technology at Aalto and VTT, but the device had more uncertainty than they had hoped for. Although it enabled them to observe the relative level, they couldn’t determine the absolute amount of energy very accurately.

This electrode-based device helps to restore movement after paralysis

Scientists have found a way to restore the brain and spinal cord interface, developing an implantable device that enables paralyzed patient to stand and walk again.

A spinal cord injury (SCI) can be debilitating for some people, making it difficult for them to walk normally again. Some individuals may take weeks to recover their ability to walk after an injury, while others may take months or even suffer from paralysis.

This is mainly due to the SCI hindering communication between the brain and the region of the spinal cord responsible for limb movement.

LIGO starts its fourth round of searching for gravitational waves and black holes

After three years of upgrading and waiting, due in part to the coronavirus pandemic, the Laser Interferometer Gravitational-wave Observatory has officially resumed its hunt for the signatures of crashing black holes and neutron stars.

“Our LIGO teams have worked through hardship during the past two-plus years to be ready for this moment, and we are indeed ready,” Caltech physicist Albert Lazzarini, the deputy director of the LIGO Laboratory, said in a news release.

Lazzarini said the engineering tests leading up to today’s official start of Observing Run 4, or O4, have already revealed a number of candidate events that have been shared with the astronomical community.

MIT’s New CRISPR-Based Gene-Editing Technique Transforms Cancer Mutation Studies

With the new method, scientists can explore many cancer mutations whose roles are unknown, helping them develop new drugs that target those mutations.

MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.
