- 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.

- 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.
