SpaceX Starlink satellites responsible for over half of close encounters in orbit, scientist says
Live Science - 19 Aug 2021 13:12
SpaceX's Starlink satellites are involved in about 1,600 close encounters between two spacecraft in low Earth orbit every week, according to available data. That's about 50% of all such incidents.
Milky Way has a 3,000-light-year-long splinter in its arm, and astronomers don't know why
Live Science - 19 Aug 2021 13:00
Astronomers discovered a 3,000-light-year-long 'break' in the Milky Way's Sagittarius spiral arm, jutting out at a wild angle.
The Brain's 'Prediction Machine' Anticipates the Future When Listening to Music
Neuroscience News - 19 Aug 2021 23:19
When it comes to anticipating how a song will progress, the human brain considers the rhythm and beats that came before.
Too Much Time on a Computer, Watching TV or Other Sedentary Activities Raises Stroke Risk
Neuroscience News - 19 Aug 2021 23:00
Adults under sixty who spend a significant amount of engaged in sedentary activities and less time embarking on physical activity have a higher stroke risk than their more active peers.
Flawed Quality Control in the Brain
Neuroscience News - 19 Aug 2021 21:50
A new mouse line makes the state of protein balance visible in the mammalian brain for the first time, allowing researchers to investigate disorders associated with protein misfolding.
Rattlesnake Rattles Trick Human Ears
Neuroscience News - 19 Aug 2021 21:28
As potential threats approach, rattlesnakes increase the rate of rattling. The switch to a high-frequency mode makes people think the snake is closer to them than it actually is.
Study of East Africans Illuminates New Genetic Factors Underlying Human Faces
Neuroscience News - 19 Aug 2021 21:10
A new genetics study reveals shared genetic sites relevant to facial shapes and features between Tanzanian children and Europeans, suggesting the genetic basis for human face shape is partly shared across different popul...
Delivering mRNA inside a human protein could help treat many diseases
New Scientist - 19 Aug 2021 21:00
It is difficult to get mRNA delivered into any cells other than liver cells but a way of packaging them with an existing human protein might help treat several diseases or conditions
Rattlesnakes use auditory illusion to make us think they are nearby
New Scientist - 19 Aug 2021 21:00
Western diamondback rattlesnakes use their rattles to produce an auditory illusion, creating the sensation that they are far closer than they really are
A Parent's Genes Can Influence a Child's Educational Success, Inherited or Not
Neuroscience News - 19 Aug 2021 20:35
Genetic nurture, the concept that the parent's genes indirectly influence their children by shaping the environment they provide for them, is almost equally important in a child's educational achievement as direct geneti...
Scientists harness human protein to deliver molecular medicines to cells
Science Daily - 19 Aug 2021 20:27
Researchers have developed a new way to deliver molecular therapies to cells. The system, called SEND, can be programmed to encapsulate and deliver different RNA cargoes.
How ions get their electrons back
Science Daily - 19 Aug 2021 20:27
Very unusual atomic states are produced at TU Wien: Ions are created by removing not just one but 20 to 40 electrons from each atom. These "highly charged ions" play an important role in current research. For a long time...
Study of East Africans illuminates new genetic factors underlying human faces
Science Daily - 19 Aug 2021 20:27
A new study of the genetics underlying facial features finds that East Africans have some unique facial genetics and some that are shared with Europeans. The findings add to our understanding of how genetics shape the hu...
Antibodies Block Specific Viruses That Cause Arthritis and Brain Infections
Neuroscience News - 19 Aug 2021 20:11
Chikungunya, and other mosquito-borne alphaviruses are known to trigger brain infections and arthritis in those who contract the infections. Researchers have identified two antibodies that protect animals from diseases c...
A master gear in the circadian clock
Science Daily - 19 Aug 2021 19:43
A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research suggests. The findi...
Varying immune cell levels in canine brain tumors could provide therapeutic targets
Science Daily - 19 Aug 2021 19:43
A new study reveals that high-grade gliomas, or brain tumors, in dogs contained more immune cells associated with suppressing immune response than low-grade gliomas.
