Researchers develop technology to tabulate and characterize every cell in the human brain
By combining non-invasive imaging techniques, investigators have created a comprehensive cellular atlas of a region of the human brain known as Broca’s area.
Americans will spend half their lives taking prescription drugs, study finds
An American born in 2019 will spend a larger share of their lifetime taking prescription drugs than being in their first marriage or receiving an education, according to new research. She found that American males will spend approximately 48% of their …
200-year-old DNA helps map tiny fly’s genetic course to new lands, modern times
Researchers have extracted and analyzed DNA from fruit flies housed in museum collections in Lund, Stockholm and Copenhagen. Surprisingly, the researchers found the fruit flies collected in Sweden in the early 1800s were more genetically similar to 21s…
Caution: Content warnings do not reduce stress, study shows
Trigger warnings are designed to help people avoid or emotionally prepare for encountering disturbing content. But those warnings heighten distress rather than alleviate it, a new research analysis shows.
New catalyst could provide liquid hydrogen fuel of the future
Researchers are investigating a car fuel comprised of a liquid that is converted to hydrogen by a solid catalyst. The used liquid is then emptied from the tank and charged with hydrogen, after which it can be used again in a circular system that is fre…
Fresh light shed on mystery of infant consciousness
There is evidence that some form of conscious experience is present by birth, and perhaps even in late pregnancy, an international team of researchers has found.
No universal body image experience in pregnancy
A new study analysing almost 9,400 responses has discovered large variations in how pregnancy can affect women’s perceptions of their body. The research is believed to be the first meta-analysis comparing pregnant women and the general female populatio…
‘A new era in brain science’: Researchers unveil human brain cell atlas
Scientists analyzed more than half a million brain cells from three human brains to identify previously unknown brain cell subtypes. Their research paves the way for understanding how certain brain cell types go awry in brain disorders and diseases.
Human Brain Cell Atlas offers unprecedented look at neuropsychiatric disorders
In a large, multi-institutional effort researchers have analyzed more than a million human brain cells and revealed links between specific types of cells and various common neuropsychiatric disorders.
Over 40 percent of Antarctica’s ice shelves reduced in volume over 25 years
71 of the 162 ice shelves that surround Antarctica have reduced in volume over 25 years from 1997 to 2021, with a net release of 7.5 trillion tons of meltwater into the oceans, say scientists. They found that almost all the ice shelves on the western …
Researchers construct first ‘multiome’ atlas of cell development in the human cerebral cortex from before birth to adulthood
A team of researchers has created the first ‘multiome’ atlas of brain cell development in the human cerebral cortex across six broad developmental time points from fetal development into adulthood, shedding new light on their roles during brain develop…
An electrical switch to control chemical reactions
New pharmaceuticals, cleaner fuels, biodegradable plastics: in order to meet society’s needs, chemists have to develop new synthesis methods to obtain new products that do not exist in their natural state. A research group has discovered how to use an …
Gray whales experience major population swings as a result of Arctic conditions
Dynamic and changing Arctic Ocean conditions have likely caused three major mortality events in the eastern North Pacific gray whale population since the 1980s.
Cell atlases of the human brain
Researchers have created the most comprehensive atlases of human brain cells to date. The studies provide clues on different brain diseases and give hope for medical advancements in the future, such as new cancer drugs.
Coffee and cocoa plants at risk from pollinator loss
Tropical crops such as coffee, cocoa, watermelon and mango may be at risk due to the loss of insect pollinators, finds a new study.
Scientists unveil detailed cell maps of the human brain and the nonhuman primate brain
A group of international scientists have mapped the genetic, cellular, and structural makeup of the human brain and the nonhuman primate brain. This understanding of brain structure allows for a deeper knowledge of the cellular basis of brain function …
Engineered bacteria paint targets on tumors for cancer-killing T cells to see
Synthetic biologists report on a new approach to attacking tumors. They have engineered tumor-colonizing bacteria (probiotics) to produce synthetic targets in tumors that direct CAR-T cells to destroy the newly highlighted cancer cells.
Honey bees may inherit altruistic behavior from their mothers
True altruism is rare behavior in animals, but a new study has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent they inherit it from.
