  • newNew double-contrast technique picks up small tumors on MRI
    Early detection of tumors is extremely important in treating cancer. A new technique offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue.

  • newStudy reveals first evidence inherited genetics can drive cancer's spread
    Scientists have long struggled to understand what drives a tumor to seed itself elsewhere in the body. New research implicates own pre-existing genetics.

  • A clue as to why it's so hard to wake up on a cold winter's morning
    Do you remember the challenge of waking up on winter's cold, dark days? Neurobiologists have uncovered a clue to what's behind this behavior. In a study of the fruit fly, the researchers have identified a 'thermometer' circuit that relays information about external cold temperature from the fly antenna to the higher brain. They show how, through this circuit, seasonally cold and dark conditions can inhibit neurons within the fly brain that promote activity and wakefulness, particularly in the mo…

  • New urine testing method holds promise for kidney stone sufferers
    An improved urine-testing system for people suffering from kidney stones inspired by nature may enable patients to receive results within 30 minutes instead of the current turnaround time of a week or more.

  • Blood flow recovers faster than brain in micro strokes
    Neurobiologists show that increased blood flow to the brain is not an accurate indicator of neuronal recovery after a microscopic stroke.

  • Cell reproduction dogma challenged
    Meiosis is essential to sexual reproduction. For almost 15 years, it has been commonly held that retinoic acid, a molecule derived from vitamin A, triggers meiosis in mammalian germ cells. Yet new research demonstrates that meiosis in mice begins and proceeds normally even in the absence of retinoic acid. These findings set the stage for new research in the field of reproductive biology.

  • Higher fiber saves lives, but food processing may remove benefits
    Eating more fiber can improve life expectancy for those with diabetes, researchers say. Type 2 diabetes has reached epidemic proportions worldwide, is associated with serious medical complications, and increases the risk of dying from COVID-19.

  • Placentas from COVID-19-positive pregnant women show injury
    In the largest study to examine health of placentas in women who tested positive for COVID-19, findings show placentas from 16 women who tested positive for COVID-19 while pregnant showed evidence of injury, according to pathological exams completed directly following birth.

  • No evidence of benefit for chloroquine and hydroxychloroquine in COVID-19 patients, study finds
    A new study finds that the use of chloroquine or hydroxychloroquine is linked to increased rates of mortality and heart arrhythmias among hospital patients with COVID-19. The authors suggest that these drug regimens should not be used to treat COVID-19 outside of clinical trials and urgent confirmation from randomised clinical trials is needed.

  • First human trial of COVID-19 vaccine finds it is safe and induces rapid immune response
    A study of 108 adults finds that the vaccine produced neutralizing antibodies and T-cell response against SARS-CoV-2, but further research is needed to confirm whether the vaccine protects against SARS-COV-2 infection.

  • No evidence blanket 'do-not-resuscitate' orders for COVID-19 patients are necessary; investigators urge caution
    It's inappropriate to consider blanket do-not-resuscitate orders for COVID-19 patients because adequate data is not yet available on US survival rates for in-hospital resuscitation of COVID-19 patients and data from China may not relate to US patients, according to a new article.

  • Glucose levels linked to maternal mortality even in non-diabetic women
    An elevated pre-pregnancy hemoglobin A1c -- which measures average blood glucose concentration -- is associated with a higher risk of adverse pregnancy outcomes even in women without known diabetes, according to a new study.

  • Algal genome provides insights into first land plants
    Cornell researchers have sequenced and analyzed the genome of a single-celled alga that belongs to the closest lineage to terrestrial plants and provides many clues to how aquatic plants first colonized land.

  • New technology can detect anti-virus antibody in 20 minutes
    Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against SARS-CoV-2, the causative virus of COVID-19.
