New York waters may be an important, additional feeding area for large whales

Science Daily - 23/09/2021
A new study finds that that some large whale species (humpback, fin and minke whales) use the waters off New York and New Jersey as a supplemental feeding area feasting on two different types of prey species.

Antibody-producing B cells may be 'predestined' for their fates

Science Daily - 23/09/2021
The master regulator behind the development of antibody-producing cells has been identified in a new study. The findings provide new insight into the inner workings of the immune system and may help understand how tissues develop and how certain cancers arise.

Physicists control the flow of electron pulses through a nanostructure channel

Science Daily - 23/09/2021
Particle accelerators are essential tools in research areas such as biology, materials science and particle physics. Researchers are always looking for more powerful ways of accelerating particles to improve existing equipment and increase capacities for experiments. One such powerful technology is dielectric laser acceleration (DLA). In this approach, particles are accelerated in the optical near-field which is created when ultra-short laser pulses are focused on a nanophotonic structure. Using this method, researchers have succeeded in guiding electrons through a vacuum channel, an essential component of particle accelerators.

How tactile vibrations create illusions

Science Daily - 23/09/2021
Among the traditional five human senses, touch is perhaps the least studied. Yet, it is solicited everywhere, all the time, and even more so in recent years with the widespread daily use of electronic devices that emit vibrations. Indeed, any moving object transmits oscillatory signals that propagate through solid substrates. Our body detects them by means of mechanoreceptors located below the skin and transmits the information to the brain similarly to auditory, olfactory or visual stimuli. By studying how mice and humans perceive tactile vibrations, researchers discovered that the brain does not reliably perceive the frequency of a vibration when its amplitude varies. An illusory phenomenon is thereby created, which highlights how far our perception of the world around us can deviate from its physical reality.

Observation of energy-difference conservation in optical domain

Science Daily - 23/09/2021
A research team proposes an efficient experimental platform for non-Hermitian physics research.

Coastal Northeastern US is a global warming hotspot; 2 degrees Celsius of summer warming has already occurred

Science Daily - 23/09/2021
New research reveals not only that the coastal Northeast -- from Maine to Delaware -- is heating faster than most regions of North America, but that this heating is linked to drastic alterations in the ocean and atmospheric conditions over the North Atlantic.

Researchers define chain of events leading to dangerous intestinal disorder in preemies

Science Daily - 23/09/2021
A research team has provided what may be the most definitive view to date of the biological process leading to necrotizing enterocolitis (NEC), a dangerous inflammatory disease that can destroy a premature infant's intestinal lining and causes death in up to a third of the cases.

Intensified water cycle slows down global warming

Science Daily - 23/09/2021
A new study shows that the intensification of global hydrological cycle drives more ocean heat uptake into the deep ocean and moderates the pace of global warming.

Breast cancers: Ruptures in cell nuclei promotes tumor invasion

Science Daily - 23/09/2021
When cells multiply and migrate, they can be compressed and their nucleus may break open. This phenomenon causes DNA damage. Scientists have now shown that this facilitates the spread of cancer cells in breast tumors.

Child abuse and neglect linked to early death in adulthood

Science Daily - 23/09/2021
A new study found that adults who reported experiencing sexual abuse by the age of 16 had a 2.6 times higher risk of dying in middle age -- that is, between 45 and 58 -- than those who did not report sexual abuse.

Ancient DNA analysis sheds light on dark event in medieval Spain

Science Daily - 23/09/2021
Researchers used ancient DNA analysis to identify a member of a population expelled from medieval Spain known as the 'Segorbe Giant'. The results have shed light on the brutal political decision that led to a dramatic change in population following the Christian reconquest of Spain.

Adjusting fatty acid intake may help with mood variability in bipolar disorders

Science Daily - 23/09/2021
Can specific dietary guidelines help people living with bipolar disorders better manage their health? Clinical trial results showed that a diet designed to alter levels of specific fatty acids consumed by participants may help patients have less variability in their mood.

A new method for removing lead from drinking water

Science Daily - 23/09/2021
Engineers designed a relatively low-cost, energy-efficient approach to treating water contaminated with heavy metals such as lead.

Researchers translate insect defense chemicals into eerie sounds

Science Daily - 23/09/2021
Sawfly larvae protect themselves by secreting cocktails of unpleasant, volatile chemicals intended to repel predators, particularly ants. Researchers can assess the effectiveness of these defenses by staging meetups, so-called bioassays, between prey and predator. But entomologist have taken a different approach, translating the secretions' chemical composition into sounds, and measuring how humans react.

Deadly virus’s pathway to infect cells identified

Science Daily - 23/09/2021
Researchers have discovered how Rift Valley fever virus enters cells, pointing the way to new therapies to treat deadly Rift Valley fever.

Therapy using dual immune system cells effectively controls neuroblastoma

Science Daily - 23/09/2021
A newly developed immunotherapy that simultaneously uses modified immune-fighting cells to home in on and attack two antigens, or foreign substances, on cancer cells was highly effective in mice implanted with human neuroblastoma tissue.

Metastatic prostate cancer comes in two forms, which could guide treatment

Science Daily - 23/09/2021
Scientists have identified two subtypes of metastatic prostate cancer that respond differently to treatment, information that could one day guide physicians in treating patients with the therapies best suited to their disease.

Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries

Science Daily - 23/09/2021
Traumatic brain injury (TBI) and other injuries to blood vessels in the brain, like stroke, are a leading cause of long-term disability or death. Researchers have found a possible explanation for why some patients recover much more poorly from brain injury if they later become infected.

How poxviruses multiply

Science Daily - 23/09/2021
Poxviruses have found a unique way of translating their genes into proteins in the infected organism. Scientists of the have been able to gain atomic-level insights into the functioning of the molecular machinery involved in the process.
